TERMINATE Command

Terminates the CICS/VSAM ECCR that is running in the CICS region. The ECCR stops capturing change data from all VSAM source data sets immediately and then disconnects from the PowerExchange Logger for z/OS. Messages that indicate the number and type of changes captured since the data sets were last opened are written to EDMMSG data set.

Also dynamically removes the PowerExchange exit programs that run at the CICS task-related user exit point and global use exit points that PowerExchange uses for CICS/VSAM CDC.

Use the EDMC TERM command only at the direction of Informatica Global Customer Support. Use of this command to terminate PowerExchange change data capture can cause data loss or other unexpected results if the exit points within the CICS region that the Power Exchange CICS/VSAM ECCR uses are also in use by other exit programs. Instead, let CICS request that the ECCR initiate its termination when you shut down the CICS region.

Syntax

Use the following command syntax:

EDMC TERMINATE

Short form:

EDMC TERM

Example Output

The following example output results from a TERMINATE command:

PWXEDM172809I Change Capture counts for EDM.ABC.EDMVES04: Insert=0, Update=20, Delete=0
PWXEDM172809I Change Capture counts for EDM.ABC.EDMVES03: Insert=10, Update=0, Delete=0
PWXEDM172809I Change Capture counts for EDM.ABC.EDMVES05: Insert=20, Update=0, Delete=0
PWXEDM172841I EDM ECCR ECCRCT41 disconnected from EDM Logger A10L, Log RBA=X'0000019EAA160000'
PWXEDM172818I Left XCF group 'A10L' as member 'ECCRCT41'
PWXEDM172829I EDM ECCR sent 50 records to Logger A10L (50 change records)

The PWXEDM172809I message is not displayed for a source data set if the Insert, Update, and Delete counts are all 0.

Usage Notes

Before you issue the EDMC TERM command, quiesce the CICS region.

If you terminate the CICS/VSAM ECCR while transactions on data sources are updating VSAM data sets that are registered for change data capture, change data loss is likely to occur.

CICS/VSAM CDC uses exit programs defined at multiple CICS global exit points to capture changes to VSAM data sets. The INIT command causes the exit programs to be dynamically added, and the TERM command causes the exit programs to be dynamically removed. If other exit programs are active at the same global exit points on the system where the CICS/VSAM ECCR runs, change data capture problems can occur if the CICS/VSAM CDC exit programs get control in the improper order.
