Starting the Adabas Log-Based ECCR

Starting the Adabas Log-Based ECCR

The Adabas log-based ECCR can run as a started task or batch job. Usually, the Adabas ECCR runs as a started task. Sample JCL for the ECCR PROC is supplied in the ECCRADA member of the RUNLIB library. When you ran the XIZZZ998 job during installation, that job copied the contents of the ECCRADA member to the
xxx
AD1EC member of the PROCLIB library, where
xxx
 is the PowerExchange Agent prefix.
Before starting the ECCR started task, perform the following tasks:
  • Create capture registrations for your Adabas change data sources.
  • Verify that the PowerExchange ECCR DBID parameter value that is specified in the ADAECRP1 member of the RUNLIB library matches the collection identifier in the Adabas capture registrations. If you use condense processing, also verify that this same DBID value is specified in the CAPTADA1 member of the RUNLIB library.
  • Verify that the specified Adabas DBID is active.

Syntax

To start the Adabas ECCR as a started task, use the MVS START (S) command: 
S 
xxx
AD1EC
The
xxx
 variable is the three-character value that you specified for the
PowerExchange Agent/Logger Prefix
 value when you ran the MVS Installation Assistant. Default is PWX. The value
xxx
AD1EC is the name of the PROCLIB member that contains the ECCR started task JCL.

Usage Notes

Review the following usage notes:
  • You must start one ECCR for each Adabas DBID or Nucleus to which PowerExchange requires access for change data capture.
  • The ECCR, PowerExchange Logger, and PowerExchange Agent must all run on the same MVS system, except in a sysplex environment that uses Post-Log Merge processing.
  • When the ECCR starts, it evaluates the PCAT data set to detect any new archived PLOG entries for capture processing. Thereafter, the ECCR checks for new PLOG entries whenever the wait period that is defined in the NO_DATA_WAIT or NO_DATA_WAIT2 parameter of the ADAECRP1 member elapses.
  • The PowerExchange ECCR terminates with return code 8 if Adabas capture registrations do not exist.
  • The first time you start the ECCR, you must perform a cold start. For more information, see the
    PowerExchange CDC Guide for z/OS
    .
  • To confirm that the PowerExchange ECCR connected to the PowerExchange Logger, review the messages in the EDMMSG data set.
