Using Multiple Journals with PowerExchange Condense

You can configure the PowerExchange change data capture environment to capture changes from more than one journal. To do this, you need to establish a PowerExchange Condense, or CONDLIB, library for each journal that you want to condense.

If you have multiple journals, or you might have them in the future, copy the supplied CONDLIB as a template before you customize or use it. Each CONDLIB library has its own CAPTPARM member that specifies the journal to be condensed.

A single PowerExchange Listener can be used for multiple PowerExchange Condense jobs and extractions from multiple journals.

Within each CONDLIB library, you must customize the CAPTPARM member to point to the appropriate journal and CONDLIB library.

For example, to run PowerExchange Condense for the first journal, configure the following parameters in condlib
/CFGCOND(CAPTPARM):

DBID=instance1 (This uses the journal in DBMOVER.)
CHKPT_BASENAME=condlib/CHKPT 
COND_DIR=condlib

To run PowerExchange Condense for a second journal, configure the following parameters in a second condlib
called condlib2
/CFGCOND(CAPTPARM):

DBID=instance2                
JRNL=library/journal2 (The journal override.)
REG=(reg1)
REG=(reg2)
REG=(reg3,DB=library/file) 
CHKPT_BASENAME=condlib2/CHKPT 
COND_DIR=condlib2

To run PowerExchange Condense for a third journal, configure the following parameters in a second condlib
called condlib3
/CFGCOND(CAPTPARM):

DBID=instance3 
JRNL=library/journal3 (The journal override.)
CHKPT_BASENAME=condlib3/CHKPT 
COND_DIR=condlib3

Capture registrations can be specified in either the CAPTPARM member or the DBMOVER configuration member but not in both members. If no capture registrations are specified, all capture registrations that specify a Condense Type other than None are included.
