Job DSNTIJIN

During installation, job DSNTIJIN defines VSAM and non-VSAM data sets for Db2.

DSNTIJIN performs the following tasks:
  • Defines three non-VSAM data sets for the Db2 sample objects:
    • prefix.DBRMLIB.DATA
    • prefix.SRCLIB.DATA
    • prefix.RUNLIB.LOAD
  • Defines the VSAM clusters for the bootstrap data sets.

    Each bootstrap data set (BSDS) consists of a VSAM key-sequenced data set. You defined the BSDS names during the ISPF tailoring session

  • Defines the VSAM clusters for the active log data sets.

    You specified up to 93 primary active log data sets during the ISPF tailoring session (NUMBER OF LOGS field on installation panel DSNTIPL). You might also have requested dual logging to generate two copies of each active log data set. Consequently, job DSNTIJIN can define up to 186 active log data sets. If you specified that DSNTIJIN is to create fewer active log data sets, then after installation, you can run the DSNJU003 utility to add additional active log data sets to the BSDS.

  • Defines the VSAM clusters for the task list data set of the administrative task scheduler.
  • Defines the VSAM clusters for the Db2 directory.
  • Defines the VSAM clusters for the Db2 catalog.
  • Invokes the LISTCAT command of access method service so that you can verify that the VSAM definitions were successful.
  • Creates control intervals based on the value you specified in VARY DS CONTROL INTERVAL on panel DSNTIP7. If you specified YES, Db2 creates 4-KB, 8-KB, 16-KB, and 32-KB control intervals as appropriate in the AMS DEFINE CLUSTER commands for the Db2 catalog and directory data sets. If you specified NO, these data sets are created using a fixed control interval of 4-KB.
