Updating the CLIST defaults input member: job DSNTIJXZ

Before you run the CLIST to migrate to Db2 13, update an existing Db2 13 subsystem, or install Db2 13 using the settings of an existing Db2 13 subsystem, update your defaults input member.

Before you begin

  • Ensure that you have configured Resource Recovery Services (RRS).

  • Start of changeOptionally, you can generate an editable configuration file where you can specify values that you want to use for configuration parameters that cannot be discovered from an existing Db2 environment. For more information, see Generating a current and valid DSNTIDxx defaults input member.End of change

  • Before running the DSNTIJXZ job, you might need to bind or refresh the package and plan for the DSNTXAZP program. The necessary bind commands are in installation job DSNTIJSG.

  • If the DSNTXAZP job action to be used is UPDATE_APPL_DEF, UPDATE_IRLM, UPDATE_LOG, or UPDATE_ALL, ensure that the following requirements are met:

    • SYSOUT data sets for started tasks are available:
      • JOBCLASS(STC) OUTPUT must be set to YES
      • OUTCLASS(x) OUTPUT must be set to PRINT or PUNCH, where x is the JOBCLASS(STC) MSGCLASS value
    • The load library with the enhanced DSNTXAZP module resides in an APF-authorized library.
    • If you plan to invoke DSNTXAZP from a TSO CALL command, you must add DNTXAZP to the AUTHPGM and AUTHTSF sections of IKJTSOxx.

  • For the following DSNTXAZP job actions, ensure that each user ID who executes DSNTXAZP has, at a minimum, the following access to JES SPOOL data sets:

    • UPDATE_APPL_DEF: READ access to the JES SPOOL JESMSGLG data set of the Db2 started task (ssidMSTR) where the DSNHDECP module name is specified.
    • UPDATE_IRLM: READ access to the JES SPOOL JESJCL data set of the IRLM started task (IRLMPROC - the IRLM startup procedure name) where the IRLM startup options are specified.
    • UPDATE_LOG: READ access to the JES SPOOL JESJCL data set of the Db2 started task (ssidMSTR) where the BSDS names are specified.
    • UPDATE_ALL: READ access to the JES SPOOL data sets listed above for the UPDATE_APPL_DEF, UPDATE_IRLM, and UPDATE_LOG actions.
  • Start of changeFor the DSNTXAZP job actions, UPDATE_JAVA or UPDATE_ALL, ensure that each user ID who executes DSNTXAZP, has at minimum, read access to the files and members in the JAVAENV, JAVAENVV, and JVMPROPS parameters.End of change

About this task

The DSNTIDxx defaults input member contains, the subsystem parameter settings, buffer pool settings, and other settings from an existing subsystem. It is used as input during your migration, update, or installation.

You can use job DSNTIJXZ to create an updated defaults input member, DSNTIDxx, which contains most of the settings from your current subsystem. Running this job reduces the effort of manually comparing settings in your current DSNTIJUZ job with the values that are defined in the defaults input member.

Procedure

To update the CLIST defaults input member:

  1. Obtain the correct version of the DSNTIJXZ job.
    • If you are preparing to migrate to Db2 13, use the Db2 12 DSNTIJXZ job on Db2 12 to create an updated migration input member for the Db2 13 installation CLIST.
    • If you are preparing to update an existing Db2 13 subsystem or install Db2 13 using the settings of an existing Db2 13 subsystem, use the Db2 13 DSNTIJXZ job to create an updated input member.
  2. Configure and run job DSNTIJXZ.
    • If you are preparing to migrate to Db2 13, specify as input your existing Db2 12 DSNTIDxx member. This member is the one that was created when you installed or migrated to Db2 12. If you do not have this member, specify as input the Db2 12 DSNTIDXA member, or the DSNTIDXB member if you use SAP.

      For Db2 data sharing, verify that job DSNTIJXZ runs on the data sharing member that you are preparing to migrate and that the input to job DSNTIJXZ is the DSNTIDxx member for that data sharing member.

    • If you are preparing to update an existing Db2 13 subsystem or install Db2 13 using the settings of an existing Db2 13 subsystem, specify as input your existing Db2 13 DSNTIDxx member. This member is the one that was created when you installed or migrated to Db2 13. If you do not have this member, specify as input the Db2 13 DSNTIDXA member, or the DSNTIDXB member if you use SAP.
    Job DSNTIJXZ uses the DSNTXAZP tool to create a copy of the specified DSNTIDxx member and update it with the current subsystem parameter settings, buffer pool settings, and other installation settings. For more information, see DSNTXAZP tool.
    Important: The DSNTXAZP tool does not update the DSNTIDxx CLIST input member with current settings for the following parameters or panel fields. Update the values as you complete the CLIST, or modify the values directly in the DSNTIDxx member:
