Configuring the Adabas ECCR JCL

Configuring the Adabas ECCR JCL

You can run the Adabas ECCR as a started task or batch job. PowerExchange supplies a sample PROC for running the ECCR as a started task.
The sample ECCR PROC is in the ECCRADA member of the RUNLIB library. The XIZZZ998 installation job copies the ECCRADA member to the PowerExchange PROCLIB library as
xxx
AD1EC. The
xxx
variable is the
PowerExchange Agent / Logger Prefix
value that you specified in the
z/OS
Installation Assistant.
To configure the PROC for your environment, you must customize some of the DD statements in the PROCLIB(
xxx
AD1EC) member and the ADARUN parameters in the RUNLIB(ADACARD1) member.
You must configure a separate Adabas ECCR for each Adabas database from which you capture change data.
  1. In the RUNLIB(ADACARD1) member, verify that the ADARUN parameters reflect the correct settings for your environment.
    For example:
    ADARUN DB=
    dbid
    ,DE=3390,SVC=249,PROG=ADASEL
    The
    dbid
    variable is the database ID.
  2. In the PROCLIB(
    xxx
    AD1EC) member, complete the following steps:
    1. Customize the following DD statements for the data sets that the ECCR started task requires:
      //DTLCACFG DD DISP=SHR,DSN=&RUNLIB(ADAECRP1) //DTLADKSD DD DISP=SHR,DSN=&HLQVS..DBdbid.PCAT //DDASSOR1 DD DISP=SHR,DSN=adabas.ASSOR //DDDATAR1 DD DISP=SHR,DSN=adabas.DATA //DDWORKR1 DD DISP=SHR,DSN=adabas.WORK
    2. If you plan to capture changes from Adabas spanned records, enter the the PARM=(ADA82) option in the EXEC statement:
      EXEC PGM=DTLCCADA,PARM=(ADA82)
      If you do not specify this PARM value, PowerExchange does not capture changes from the source files that include spanned records.
  3. In the RUNLIB(ADAECRP1) member, verify that the Adabas ECCR DBID parameter value is correct.
    The DBID value must match the collection identifier that is specified in the registration group that includes the capture registrations for the CDC sources.
  4. If you use PowerExchange Condense, verify that the DBID parameter in the RUNLIB(CAPTADA1) member is correct.
    The DBID parameter must match the collection identifier that is specified in the registration group.
