Commands for Controlling DB2 ECCR Processing

Commands for Controlling DB2 ECCR Processing

You can control the DB2 ECCR either by issuing MVS MODIFY commands to the ECCR. You can also change configuration statements in the REPL2OPT DD file and then issue the REFRESH command or restart the ECCR.
The following table summarizes the MVS MODIFY commands that you can use to control the DB2 ECCR:
Command
Description
DISPLAY
Prints statistics reports on ECCR activity.
QUIESCE
Stops the DB2 ECCR after all in-flight UOWs for the ECCR complete and the ECCR sends the change records to the PowerExchange Logger.
REFRESH
Refreshes the ECCR after you update configuration statements in the REPDB2OP member in the RUNLIB library or after you add, edit, or delete capture registrations for DB2 source tables. The refresh operation activates the new DB2 ECCR options and registration changes for change data capture. You can refresh the DB2 ECCR only while it is active.
The REFRESH command ignores any changes that you make to the CA NAME statement in the REPL2CTL data set and to the IFI306 and START statements in the REPL2OPT data set. The REFRESH command is equivalent to stopping the DB2 ECCR and then restarting it with the START WARM statement.
URID
Lists the DB2 URIDs for the DB2 subsystem or data-sharing group to which the DB2 for z/OS ECCR is connected.
Other DB2 ECCR MODIFY command are primarily for use by Informatica Global Customer Support. For more information, see the
PowerExchange Command Reference
.
You can also use the MVS START and STOP commands to start and stop the ECCR started task or job. The STOP command stops the DB2 ECCR immediately without waiting for in-flight UOWs to complete or for change records to be sent to the PowerExchange Logger. Informatica recommends that you use the QUIESCE command instead.
