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.
In
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).
Procedure
To migrate from conversion mode (from Version 8 or Version 9) to new-function
mode:
- Migrate from conversion mode (from Version 8 or Version 9) to
enabling-new-function mode (from Version 8 or Version
9).
- Run the installation CLIST with the ENFM option. During
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.
If
you migrated from Version 8, the CLIST also
generates job DSNTIJNX.
- 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.
- Run installation job DSNTIJEN.
Avoid updates to
the DB2 catalog and directory while job
DSNTIJEN is running.
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.
- 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.
- 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.
