More data can be saved into Near Term History (NTH) VSAM data sets with OMEGAMON XE for DB2 PE/PM on z/OS V5.1.0

Troubleshooting


Problem

The former versions of OMEGAMON DB2 PE/PM support a maximum of 10 NTH VSAM data sets.

Symptom

The former versions of OMEGAMON DB2 PE/PM support a maximum of 10 NTH VSAM data sets.

Resolving The Problem


Version 5.1.0 of OMEGAMON XE for DB2 DB2 PE/PM now supports a maximum of 20 NTH VSAM data sets. This doubles the amount of NTH data for display.

Because the ICAT dialog supports the definition and creation of the first 3 VSAM data sets, you will have to define the additional VSAM data sets by editing two generated members:

1)
The ICAT generated member COPTssid in your run-time library "hlq.RKD2PAR" contains the NTH definition including the VSAM data set names. Just extend the H2DATASET parameter with the additional amount of VSAM data set names - up to 20 are allowed, for example:

      H2DATASET(
      D01SYS.KO2.V510.RTE.RKD2VS01
      D01SYS.KO2.V510.RTE.RKD2VS02
      D01SYS.KO2.V510.RTE.RKD2VS03
      ...
      D01SYS.KO2.V510.RTE.RKD2VSnn
      )

2)
The ICAT generated member/job ALLOCDS in your run-time library "hlq.RKD2SAM" contains the DEFINE CLUSTER definitions for the VSAM data sets, replicate for each added VSAM data set, edit, adjust the size, and execute the job, for example:
      LISTC -
      ENTRIES('D01SYS.KO2.V510.RTE.RKD2VSnn') -
      NAME
      IF LASTCC GT 0 THEN DO
      SET LASTCC = 0
      SET MAXCC = 0
      DEFINE CLUSTER -
      (NAME(D01SYS.KO2.V510.RTE.RKD2VSnn) -
      CYLINDERS(x 0) -
      STORCLAS(SMS) -
      SHAREOPTIONS(2,3) -
      LINEAR)
      END


Finally stop and restart your OMEGAMON started task.
