Compatibility between code pages is used for accurate data movement when the Informatica Sever runs in the Unicode data movement mode. If the code pages are identical, then there will not be any data loss. One code page can be a subset or superset of another. For accurate data movement, the target code page must be a superset of the source code page.Superset - A code page is a superset of another...

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,...

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 processing: 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...

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.

Configure the session to partition source data. Install the informatica server on a machine with multiple CPU’s.

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.

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...

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

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...

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.

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 flexible U can export objects into repository and import objects from repository.when...

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...

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:...

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...

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...

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...

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...

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,...

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...

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.
