Informatica Faq's

7. What is the maplet? Maplet is a set of transformations that you build in the maplet designer and U can use in multiple mappings

8. What is a transformation? It is a repository object that generates, modifies or passes data
can U improve session performance in aggregator transformation? Use sorted input

29.What r the types of lookup? Connected and unconnected

35.How the informatica server sorts the string values in Ranktransformation?

When the informatica server runs in the ASCII data movement mode it sorts session data using Binary sortorder.If U configure the seeion to use a binary sort order,the informatica server caluculates the binary value of each string and returns the specified number of rows with the higest binary values for the string

36.What r the rank caches?

During the session ,the informatica server compares an inout row with rows in the datacache.If the input row out-ranks a stored row,the informatica server replaces the stored row with the input row.The informatica server stores group information in an index cache and row data in a data cache

37.What is the Rankindex in Ranktransformation?

The Designer automatically creates a RANKINDEX port for each Rank transformation. The Informatica Server uses the Rank Index port to store the ranking position for each record in a group. For example, if you create a Rank transformation that ranks the top 5 salespersons for each quarter, the rank index numbers the salespeople from 1 to 5:

38.What is the Router transformation?

A Router transformation is similar to a Filter transformation because both transformations allow you to use a condition to test data. However, a Filter transformation tests data for one condition and drops the rows of data that do not meet the condition. A Router transformation tests data for one or more conditions and gives you the option to route rows of data that do not meet any of the conditions to a default output group.

If you need to test the same input data based on multiple conditions, use a Router Transformation in a mapping instead of creating multiple Filter transformations to perform the same task

39.What r the types of groups in Router transformation? Input group Output group

The designer copies property information from the input ports of the input group to create a set of output ports for each output group

Two types of output groups

User defined groups

Default group

U can not modify or delete default groups

40.Why we use stored procedure transformation? For populating and maintaining data bases

42.What r the types of data that passes between informatica server and stored procedure?

3 types of data

Input/Out put parameters

Return Values

Status code

43.What is the status code?

Status code provides error handling for the informatica server during the session.The stored procedure issues a status code that notifies whether or not stored procedure completed sucessfully.This value can not seen by the user.It only used by the informatica server to determine whether to continue running the session or stop

44. What is source qualifier transformation?

When U add a relational or a flat file source definition to a maping,U need to connect it to

a source qualifer transformation.The source qualifier transformation represnets the records

that the informatica server reads when it runs a session

45.What r the tasks that source qualifier performs?

Join data originating from same source data base

Filter records when the informatica server reads source data

Specify an outer join rather than the default inner join

specify sorted records

Select only distinct values from the source

Creating custom query to issue a special SELECT statement for the informatica server to read

source data

46. What is the target load order?

U specify the target loadorder based on source qualifiers in a maping.If u have the multiple

source qualifiers connected to the multiple targets,U can designatethe order in which informatica

server loads data into the targets

47.What is the default join that source qualifier provides?

Inner equi join

48. What r the basic needs to join two sources in a source qualifier?

Two sources should have primary and Foreign key relation ships

Two sources should have matching data types

49.what is update strategy transformation ?

This transformation is used to maintain the history data or just most recent changes in to target


50.Describe two levels in which update strategy transformation sets?

Within a session. When you configure a session, you can instruct the Informatica Server to either treat all records in the same way (for example, treat all records as inserts), or use instructions coded into the session mapping to flag records for different database operations.

Within a mapping. Within a mapping, you use the Update Strategy transformation to flag records for insert, delete, update, or reject.

51.What is the default source option for update stratgey transformation?

Data driven

52. What is Datadriven?

The informatica server follows instructions coded into update strategy transformations with

in the session maping determine how to flag records for insert,update,,delete or reject

If u do not choose data driven option setting,the informatica server ignores all update strategy

transformations in the mapping

53.What r the options in the target session of update strategy transsformatioin?




Update as update

Update as insert

Update esle insert

Truncate table

54. What r the types of maping wizards that r to be provided in Informatica?

The Designer provides two mapping wizards to help you create mappings quickly and easily. Both wizards are designed to create mappings for loading and maintaining star schemas, a series of dimensions related to a central fact table.

Getting Started Wizard. Creates mappings to load static fact and dimension tables, as well as slowly growing dimension tables.

Slowly Changing Dimensions Wizard. Creates mappings to load slowly changing dimension tables based on the amount of historical dimension data you want to keep and the method you choose to handle historical dimension data.

55. What r the types of maping in Getting Started Wizard?

Simple Pass through maping :

Loads a static fact or dimension table by inserting all rows. Use this mapping when you want to drop all existing data from your table before loading new data.

Slowly Growing target :

Loads a slowly growing fact or dimension table by inserting new rows. Use this mapping to load new data when existing data does not require updates.

56. What r the mapings that we use for slowly changing dimension table?

Type1: Rows containing changes to existing dimensions are updated in the target by overwriting the existing dimension. In the Type 1 Dimension mapping, all rows contain current dimension data.

Use the Type 1 Dimension mapping to update a slowly changing dimension table when you do not need to keep any previous versions of dimensions in the table.

Type 2: The Type 2 Dimension Data mapping inserts both new and changed dimensions into the target. Changes are tracked in the target table by versioning the primary key and creating a version number for each dimension in the table.

Use the Type 2 Dimension/Version Data mapping to update a slowly changing dimension table when you want to keep a full history of dimension data in the table. Version numbers and versioned primary keys track the order of changes to each dimension.

Type 3: The Type 3 Dimension mapping filters source rows based on user-defined comparisons and inserts only those found to be new dimensions to the target. Rows containing changes to existing dimensions are updated in the target. When updating an existing dimension, the Informatica Server saves existing data in different columns of the same row and replaces the existing data with the updates

57.What r the different types of Type2 dimension maping?

Type2 Dimension/Version Data Maping: In this maping the updated dimension in the source will gets inserted in target along with a new version number.And newly added dimension

in source will inserted into target with a primary key

Type2 Dimension/Flag current Maping: This maping is also used for slowly changing dimensions.In addition it creates a flag value for changed or new dimension

Flag indiactes the dimension is new or newlyupdated.Recent dimensions will gets saved with cuurent flag value 1. And updated dimensions r saved with the value 0

Type2 Dimension/Effective Date Range Maping: This is also one flavour of Type2 maping used for slowly changing dimensions.This maping also inserts both new and changed dimensions in to the target.And changes r tracked by the effective date range for each version of each dimension

58.How can u recognise whether or not the newly added rows in the source r gets insert in the target ?

In the Type2 maping we have three options to recognise the newly added rows

Version number


Effective date Range

59. What r two types of processes that informatica runs the session?

Load manager Process: Starts the session, creates the DTM process, and sends post-session email when the session completes

The DTM process. Creates threads to initialize the session, read, write, and transform data, and handle pre- and post-session operations.

60. What r the new features of the server manager in the informatica 5.0?

U can use command line arguments for a session or batch.This allows U to change the values of session parameters,and mapping parameters and maping variables

Parallel data processig: This feature is available for powercenter only.If we use the informatica server on a SMP system,U can use multiple CPU's to process a session concurently

Process session data using threads: Informatica server runs the session in two processes.Explained in previous question

61. Can u generate reports in Informatcia?

Yes. By using Metadata reporter we can generate reports in informatica

62.What is metadata reporter?

It is a web based application that enables you to run reports againist repository metadata

With a meta data reporter,u can access information about U'r repository with out having knowledge of sql,transformation language or underlying tables in the repository

63.Define maping and sessions?

Maping: It is a set of source and target definitions linked by transformation objects that define the rules for transformation

Session : It is a set of instructions that describe how and when to move data from source to targets

64.Which tool U use to create and manage sessions and batches and to monitor and stop the informatica server?

Informatica server manager

65.Why we use partitioning the session in informatica?

Partitioning achieves the session performance by reducing the time period of reading the source and loading the data into target

66.To achieve the session partition what r the necessary tasks u have to do?

Configure the session to partition source data

Install the informatica server on a machine with multiple CPU's

67.How the informatica server increases the session performance through partitioning the source?

For a relational sources informatica server creates multiple connections for each parttion of a single source and extracts seperate range of data for each connection.Informatica server reads multiple partitions of a single source concurently.Similarly for loading also informatica server creates multiple connections to the target and loads partitions of data concurently

For XML and file sources,informatica server reads multiple files concurently.For loading the data informatica server creates a seperate file for each partition(of a source file).U can choose to merge the targets

68. Why u use repository connectivity?

When u edit,schedule the sesion each time,informatica server directly communicates the repository to check whether or not the session and users r valid.All the metadata of sessions and mappings will be stored in repository

69.What r the tasks that Loadmanger process will do?

Manages the session and batch scheduling: Whe u start the informatica server the load maneger launches and queries the repository for a list of sessions configured to run on the informatica server.When u configure the session the loadmanager maintains list of list of sessions and session start times.When u sart a session loadmanger fetches the session information from the repository to perform the validations and verifications prior to starting DTM process

Locking and reading the session: When the informatica server starts a session lodamaager locks the session from the repository.Locking prevents U starting the session again and again

Reading the parameter file: If the session uses a parameter files,loadmanager reads the parameter file and verifies that the session level parematers are declared in the file

Verifies permission and privelleges: When the sesson starts load manger checks whether or not the user have privelleges to run the session

Creating log files: Loadmanger creates logfile contains the status of session

70. What is DTM process?

After the loadmanger performs validations for session,it creates the DTM process.DTM is to create and manage the threads that carry out the session tasks.I creates the master thread.Master thread creates and manges all the other threads

71. What r the different threads in DTM process?

Master thread: Creates and manages all other threads

Maping thread: One maping thread will be creates for each session.Fectchs session and maping information

Pre and post session threads: This will be created to perform pre and post session operations

Reader thread: One thread will be created for each partition of a source.It reads data from source

Writer thread: It will be created to load data to the target

Transformation thread: It will be created to tranform data

72.What r the data movement modes in informatcia?

Datamovement modes determines how informatcia server handles the charector data.U choose the datamovement in the informatica server configuration settings.Two types of datamovement modes avialable in informatica

ASCII mode

Uni code mode

73. What r the out put files that the informatica server creates during the session running?

Informatica server log: Informatica server(on unix) creates a log for all status and error messages(default name: pm.server.log).It also creates an error log for error messages.These files will be created in informatica home directory

Session log file: Informatica server creates session log file for each session.It writes information about session into log files such as initialization process,creation of sql commands for reader and writer threads,errors encountered and load summary.The amount of detail in session log file depends on the tracing level that u set

Session detail file: This file contains load statistics for each targets in mapping.Session detail include information such as table name,number of rows written or rejected.U can view this file by double clicking on the session in monitor window

Performance detail file: This file contains information known as session performance details which helps U where performance can be improved.To genarate this file select the performance detail option in the session property sheet

Reject file: This file contains the rows of data that the writer does notwrite to targets

Control file: Informatica server creates control file and a target file when U run a session that uses the external loader.The control file contains the information about the target flat file such as data format and loading instructios for the external loader

Post session email: Post session email allows U to automatically communicate information about a session run to designated recipents.U can create two different messages.One if the session completed sucessfully the other if the session fails

Indicator file: If u use the flat file as a target,U can configure the informatica server to create indicator file.For each target row,the indicator file contains a number to indicate whether the row was marked for insert,update,delete or reject

output file: If session writes to a target file,the informatica server creates the target file based on file prpoerties entered in the session property sheet

Cache files: When the informatica server creates memory cache it also creates cache files.For the following circumstances informatica server creates index and datacache files

Aggreagtor transformation

Joiner transformation

Rank transformation

Lookup transformation

74.In which circumstances that informatica server creates Reject files?

When it encounters the DD_Reject in update strategy transformation

Violates database constraint

Filed in the rows was truncated or overflowed

75. What is polling?

It displays the updated information about the session in the monitor window. The monitor window displays the status of each session when U poll the informatica server

76. Can u copy the session to a different folder or repository?

Yes. By using copy session wizard u can copy a session in a different folder or repository.But that

target folder or repository should consists of mapping of that session

If target folder or repository is not having the maping of copying session ,

u should have to copy that maping first before u copy the session

77. What is batch and describe about types of batches?

Grouping of session is known as batch.Batches r two types

Sequential: Runs sessions one after the other

Concurrent: Runs session at same time

If u have sessions with source-target dependencies u have to go for sequential batch to start the

sessions one after another.If u have several independent sessions u can use concurrent batches

Whch runs all the sessions at the same time

78. Can u copy the batches? NO

79.How many number of sessions that u can create in a batch? Any number of sessions

80.When the informatica server marks that a batch is failed?

If one of session is configured to run if previous completes and that previous session fails

81. What is a command that used to run a batch? pmcmd is used to start a batch

82. What r the different options used to configure the sequential batches? Two options

Run the session only if previous session completes sucessfully. Always runs the session

83. In a sequential batch can u run the session if previous session fails?

Yes.By setting the option always runs the session

84. Can u start a batches with in a batch?

U can not. If u want to start batch that resides in a batch,create a new independent batch and copy the necessary sessions into the new batch

85. Can u start a session inside a batch idividually?

We can start our required session only in case of sequential batch.in case of concurrent batch

we cant do like this

86. How can u stop a batch? By using server manager or pmcmd

87. What r the session parameters?

Session parameters r like maping parameters,represent values U might want to change between

sessions such as database connections or source files

Server manager also allows U to create userdefined session parameters.Following r user defined

session parameters

Database connections

Source file names: use this parameter when u want to change the name or location of

session source file between session runs

Target file name : Use this parameter when u want to change the name or location of

session target file between session runs

Reject file name : Use this parameter when u want to change the name or location of

session reject files between session runs

88. What is parameter file?

Parameter file is to define the values for parameters and variables used in a session.A parameter

file is a file created by text editor such as word pad or notepad

U can define the following values in parameter file

Maping parameters

Maping variables

session parameters

89. How can u access the remote source into U'r session?

Relational source: To acess relational source which is situated in a remote place ,u need to

configure database connection to the datasource

FileSource : To access the remote source file U must configure the FTP connection to the

host machine before u create the session

Hetrogenous : When U'r maping contains more than one source type,the server manager creates

a hetrogenous session that displays source options for all types

90. What is difference between partioning of relatonal target and partitioning of file targets?

If u parttion a session with a relational target informatica server creates multiple connections

to the target database to write target data concurently.If u partition a session with a file target

the informatica server creates one target file for each partition.U can configure session properties

to merge these target files

91. what r the transformations that restricts the partitioning of sessions?

Advanced External procedure tranformation and External procedure transformation: This

transformation contains a check box on the properties tab to allow partitioning

Aggregator Transformation: If u use sorted ports u can not parttion the assosiated source

Joiner Transformation : U can not partition the master source for a joiner transformation

Normalizer Transformation

XML targets

92. Performance tuning in Informatica?

The goal of performance tuning is optimize session performance so sessions run during the available load window for the Informatica Server.Increase the session performance by following

The performance of the Informatica Server is related to network connections. Data generally moves across a network at less than 1 MB per second, whereas a local disk moves data five to twenty times faster. Thus network connections ofteny affect on session performance.So aviod netwrok connections

Flat files: If u'r flat files stored on a machine other than the informatca server, move those files to the machine that consists of informatica server

Relational datasources: Minimize the connections to sources ,targets and informatica server to

improve session performance.Moving target database into server system may improve session


Staging areas: If u use staging areas u force informatica server to perform multiple datapasses

Removing of staging areas may improve session performance

U can run the multiple informatica servers againist the same repository.Distibuting the session load to multiple informatica servers may improve session performance

Run the informatica server in ASCII datamovement mode improves the session performance.Because ASCII datamovement mode stores a character value in one byte.Unicode mode takes 2 bytes to store a character

If a session joins multiple source tables in one Source Qualifier, optimizing the query may improve performance. Also, single table select statements with an ORDER BY or GROUP BY clause may benefit from optimization such as adding indexes.

We can improve the session performance by configuring the network packet size,which allows

data to cross the network at one time.To do this go to server manger ,choose server configure database connections

If u r target consists key constraints and indexes u slow the loading of data.To improve the session performance in this case drop constraints and indexes before u run the session and rebuild them after completion of session

Running a parallel sessions by using concurrent batches will also reduce the time of loading the

data.So concurent batches may also increase the session performance

Partittionig the session improves the session performance by creating multiple connections to sources and targets and loads data in paralel pipe lines

In some cases if a session contains a aggregator transformation ,u can use incremental aggregation to improve session performance

Aviod transformation errors to improve the session performance

If the sessioin containd lookup transformation u can improve the session performance by enabling the look up cache

If U'r session contains filter transformation ,create that filter transformation nearer to the sources

or u can use filter condition in source qualifier

Aggreagator,Rank and joiner transformation may oftenly decrease the session performance .Because they must group data before processing it.To improve session performance in this case use sorted ports option

92. What is difference between maplet and reusable transformation?

Maplet consists of set of transformations that is reusable.A reusable transformation is a

single transformation that can be reusable

If u create a variables or parameters in maplet that can not be used in another maping or maplet.Unlike the variables that r created in a reusable transformation can be usefull in any other maping or maplet

We can not include source definitions in reusable transformations.But we can add sources to a maplet

Whole transformation logic will be hided in case of maplet.But it is transparent in case of reusable transformation

We cant use COBOL source qualifier,joiner,normalizer transformations in maplet.Where as we can make them as a reusable transformations

93. Define informatica repository?

The Informatica repository is a relational database that stores information, or metadata, used by the Informatica Server and Client tools. Metadata can include information such as mappings describing how to transform source data, sessions indicating when you want the Informatica Server to perform the transformations, and connect strings for sources and targets.

The repository also stores administrative information such as usernames and passwords, permissions and privileges, and product version.

Use repository manager to create the repository.The Repository Manager connects to the repository database and runs the code needed to create the repository tables.Thsea tables

stores metadata in specific format the informatica server,client tools use

94. What r the types of metadata that stores in repository?

Following r the types of metadata that stores in the repository

Database connections

Global objects



Multidimensional metadata

Reusable transformations

Sessions and batches

Short cuts

Source definitions

Target defintions


95. What is power center repository?

The PowerCenter repository allows you to share metadata across repositories to create a data mart domain. In a data mart domain, you can create a single global repository to store metadata used across an enterprise, and a number of local repositories to share the global metadata as needed

96. How can u work with remote database in informatica?did u work directly by using remote


To work with remote datasource u need to connect it with remote connections.But it is not

preferable to work with that remote source directly by using remote connections .Instead u bring that source into U r local machine where informatica server resides.If u work directly with remote source the session performance will decreases by passing less amount of data across the network in a particular time

97. What r the new features in Informatica 5.0?

U can Debug U'r maping in maping designer

U can view the work space over the entire screen

The designer displays a new icon for a invalid mapings in the navigator window

U can use a dynamic lookup cache in a lokup transformation

Create maping parameters or maping variables in a maping or maplet to make mapings more


U can export objects into repository and import objects from repository.when u export a repository object,the designer or server manager creates an XML file to describe the repository metadata

The designer allows u to use Router transformation to test data for multiple conditions.Router transformation allows u route groups of data to transformation or target

U can use XML data as a source or target

Server Enahancements:

U can use the command line program pmcmd to specify a parameter file to run sessions or batches.This allows you to change the values of session parameters, and mapping parameters and variables at runtime.

If you run the Informatica Server on a symmetric multi-processing system, you can use multiple CPUs to process a session concurrently. You configure partitions in the session properties based on source qualifiers. The Informatica Server reads, transforms, and writes partitions of data in parallel for a single session. This is avialable for Power center only

Informatica server creates two processes like loadmanager process,DTM process to run the sessions

Metadata Reporter: It is a web based application which is used to run reports againist repository metadata

U can copy the session across the folders and reposotories using the copy session wizard in the informatica server manager

With new email variables, you can configure post-session email to include information, such as the mapping used during the session

98. what is incremantal aggregation?

When using incremental aggregation, you apply captured changes in the source to aggregate calculations in a session. If the source changes only incrementally and you can capture changes, you can configure the session to process only those changes. This allows the Informatica Server to update your target incrementally, rather than forcing it to process the entire source and recalculate the same calculations each time you run the session.

99. What r the scheduling options to run a sesion?

U can shedule a session to run at a given time or intervel,or u can manually run the session

Different options of scheduling

Run only on demand: server runs the session only when user starts session explicitly

Run once: Informatica server runs the session only once at a specified date and time

Run every: Informatica server runs the session at regular intervels as u configured

Customized repeat: Informatica server runs the session at the dats and times secified in the repeat dialog box

100 .What is tracing level and what r the types of tracing level?

Tracing level represents the amount of information that informatcia server writes in a log file

Types of tracing level



Verbose init

Verbose data

101. What is difference between stored procedure transformation and external procedure transformation?

In case of storedprocedure transformation procedure will be compiled and executed in a relational data source.U need data base connection to import the stored procedure in to u'r maping.Where as in external procedure transformation procedure or function will be executed out side of data source.Ie u need to make it as a DLL to access in u r maping.No need to have data base connection in case of external procedure transformation

102. Explain about Recovering sessions?

If you stop a session or if an error causes a session to stop, refer to the session and error logs to determine the cause of failure. Correct the errors, and then complete the session. The method you use to complete the session depends on the properties of the mapping, session, and Informatica Server configuration.

Use one of the following methods to complete the session:

· Run the session again if the Informatica Server has not issued a commit.

· Truncate the target tables and run the session again if the session is not recoverable

· Consider performing recovery if the Informatica Server has issued at least one commit

103. If a session fails after loading of 10,000 records in to the target.How can u load the records from 10001 th record when u run the session next time?

As explained above informatcia server has 3 methods to recovering the sessions.Use performing recovery to load the records from where the session fails

104. Explain about perform recovery?

When the Informatica Server starts a recovery session, it reads the OPB_SRVR_RECOVERY table and notes the row ID of the last row committed to the target database. The Informatica Server then reads all sources again and starts processing from the next row ID. For example, if the Informatica Server commits 10,000 rows before the session fails, when you run recovery, the Informatica Server bypasses the rows up to 10,000 and starts loading with row 10,001.

By default, Perform Recovery is disabled in the Informatica Server setup. You must enable Recovery in the Informatica Server setup before you run a session so the Informatica Server can create and/or write entries in the OPB_SRVR_RECOVERY table.

105. How to recover the standalone session?

A standalone session is a session that is not nested in a batch. If a standalone session fails, you can run recovery using a menu command or pmcmd. These options are not available for batched sessions.

To recover sessions using the menu:

1. In the Server Manager, highlight the session you want to recover.

2. Select Server Requests-Stop from the menu.

3. With the failed session highlighted, select Server Requests-Start Session in Recovery Mode from the menu.

To recover sessions using pmcmd:

1.From the command line, stop the session.

2. From the command line, start recovery

106. How can u recover the session in sequential batches?

If you configure a session in a sequential batch to stop on failure, you can run recovery starting with the failed session. The Informatica Server completes the session and then runs the rest of the batch. Use the Perform Recovery session property

To recover sessions in sequential batches configured to stop on failure:

1.In the Server Manager, open the session property sheet.

2.On the Log Files tab, select Perform Recovery, and click OK.

3.Run the session.

4.After the batch completes, open the session property sheet.

5.Clear Perform Recovery, and click OK.

If you do not clear Perform Recovery, the next time you run the session, the Informatica Server attempts to recover the previous session

If you do not configure a session in a sequential batch to stop on failure, and the remaining sessions in the batch complete, recover the failed session as a standalone session.

107. How to recover sessions in concurrent batches?

If multiple sessions in a concurrent batch fail, you might want to truncate all targets and run the batch again. However, if a session in a concurrent batch fails and the rest of the sessions complete successfully, you can recover the session as a standalone session.

To recover a session in a concurrent batch:

1.Copy the failed session using Operations-Copy Session.

2.Drag the copied session outside the batch to be a standalone session.

3.Follow the steps to recover a standalone session.

4.Delete the standalone copy.

108. How can u complete unrcoverable sessions?

Under certain circumstances, when a session does not complete, you need to truncate the target tables and run the session from the beginning. Run the session from the beginning when the Informatica Server cannot run recovery or when running recovery might result in inconsistent data.

109. What r the circumstances that infromatica server results an unreciverable session?

The source qualifier transformation does not use sorted ports

If u change the partition information after the initial session fails

Perform recovery is disabled in the informatica server configuration

If the sources or targets changes after initial session fails

If the maping consists of sequence generator or normalizer transformation

If a concuurent batche contains multiple failed sessions

110. If i done any modifications for my table in back end does it reflect in informatca warehouse or maping desginer or source analyzer?

NO. Informatica is not at all concern with back end data base.It displays u all the information
that is to be stored in repository.If want to reflect back end changes to informatica screens,

again u have to import from back end to informatica by valid connection.And u have to replace the existing files with imported files

111. After draging the ports of three sources(sql server,oracle,informix) to a single source qualifier, can u map these three ports directly to target?

NO. Unless and until u join those three ports in source qualifier u cannot map them directly
