CAPT_STATS Parameter

CAPT_STATS Parameter

Controls whether PowerExchange writes ECCR statistics messages to the DTLLOG and DTLOUT data sets and WTO messages to the system operator console when the IMS log-based ECCR finishes processing a SLDS.
IMS log-based ECCR statistics reporting is supported only for the ECCR DTLCCIMX program that works with the DBRC API. PowerExchange supplies the DTLCCIMX program for IMS 10 and later.
The ECCR issues PWX-06153 messages that report the number of inserts, deletes, and updates that were captured for each registration, grouped by SLDS. The WTO messages also notify the system operator that a SLDS was closed and provide capture counts.
Regardless of the CAPT_STATS setting, the ECCR always reports the total number of inserts, deletes, updates, and commits across all of the SLDSs at the end of the ECCR run.
CAPT_STATS_INTVL, CAPT_STATS_TERSE
CAPT_STATS={
N
|Y}
  • N
    . Do not write the ECCR capture statistics messages to the DTLLOG and DTLOUT data sets and WTO capture count messages when the ECCR finishes processing each SLDS.
  • Y
    . Write the ECCR capture statistics messages to the DTLLOG and DTLOUT data sets and WTO capture count messages when the ECCR finishes processing each SLDS.
Default is N.
  • If you do not set the global CAPT_STATS parameter to Y, you can issue to STATISTICS ON command after the ECCR is started to enable statistics reporting for each SLDS.
  • If you also specify the CAPT_STATS_INTVL parameter or run the STATISTICS
    minutes
    , the ECCR also reports the total number of inserts, deletes, updates, and commits for the each interval.
