Migrating your DB2 subsystem to new-function mode

After you migrate your DB2® subsystem to conversion mode (from Version 8 or Version 9), you must complete the migration to DB2 10 new-function mode by migrating the catalog.

About this task

Important: After you begin enabling-new-function mode (from Version 8 or Version 9), you cannot fall back to the previous release.

Start of changeIn a data sharing group, you complete this task only one time on a single member. Other members can be active when you complete this task, but all active members must be running in DB2 10 conversion mode (from Version 8 or Version 9). End of change

Procedure

To migrate from conversion mode (from Version 8 or Version 9) to new-function mode:

  1. Migrate from conversion mode (from Version 8 or Version 9) to enabling-new-function mode (from Version 8 or Version 9).
    1. Run the installation CLIST with the ENFM option. Start of changeDuring enabling-new-function mode (from Version 8 or Version 9) processing, the CLIST generates installation jobs DSNTIJCS, DSNTIJEN, DSNTIJES, DSNTIJNF, DSNTIJNG, and DSNTIJNH, and customizes the DB2 10 IVP jobs.End of change

      Start of changeBegin DB2 Version 8 to DB2 10 migration informationIf you migrated from Version 8, the CLIST also generates job DSNTIJNX.End DB2 Version 8 to DB2 10 migration informationEnd of change

    2. Create the following copies for backup purposes:
      • An image copy of the DB2 catalog and directory, using your site's backup and recovery procedure. You cannot use this image copy to do a point-in-time recovery of the catalog and directory table spaces, because of table space attribute changes during enabling-new-function mode.
      • Optional: A full DFDSS backup of the DB2 subsystem.
    3. Run installation job DSNTIJEN. Start of changeAvoid updates to the DB2 catalog and directory while job DSNTIJEN is running. End of change
      Important: Job DSNTIJEN converts DB2 to enabling-new-function mode (from Version 8 or Version 9), from which you cannot fall back. Do not run DSNTIJEN until you are certain that you will not need to fall back.
      After job DSNTIJEN finishes, catalog migration is complete. You can then run job DSNTIJNF to move the subsystem to new-function mode.
  2. Complete enabling-new-function mode (from Version 8 or Version 9) processing. For details, see Completing enabling-new-function mode (from Version 8 or Version 9) processing.
  3. Migrate from enabling-new-function mode (from Version 8 or Version 9) to new-function mode. For details, see Migrating from enabling-new-function mode (from Version 8 or Version 9) to new-function mode.
