DSNT567I Enter values for activating Db2 function levels after initial migration to V13R1M100

System action

For a z/OSMF-driven migration of a Db2 subsystem or the first member of a data sharing group to Db2 13, the CLIST produces two sets of z/OSMF workflows and variable files:

• DSNTIWMS and DSNTIVMS for initial migration to function level 100 (V13R1M100)
• DSNTIWMN and DSNTIVMN for activating function levels.

The CLIST also produces a single set of JCL templates in the prefix.NEW.SDSNSAM2 for use by both workflows. To support sharing of the JCL templates, the settings for the function level, default application compatibility level, and the precompiler SQL level are handled as z/OSMF variables rather than constants.

For initial migration to function level 100 (DSNTIWMS and DSNTIVMS), the z/OSMF variable for the function level is always set to V13R1M500, the z/OSMF variable for the default application compatibility level is set to the migration input setting, and the z/OSMF variable for the precompiler SQL level is always set to V13R1M100.

For activating function levels after migration to V13R1M100 (DSNTIWMN and DSNTIVMN), the z/OSMF variables for the function level, the default application compatibility level, and the precompiler SQL level are set from the values entered on DSNTIP00.
