Problem summary
**************************************************************** * USERS AFFECTED: All DB2 11 for z/OS users migrating to DB2 * * 12 for z/OS. * **************************************************************** * PROBLEM DESCRIPTION: Toleration of fallback from DB2 12 for * * z/OS. * * * * In a Data Sharing environment, required * * for coexistence of DB2 12 for z/OS with * * DB2 11 for z/OS. * **************************************************************** * RECOMMENDATION: * **************************************************************** This APAR must be applied to all members of a data sharing group and DB2 11 started on all members before one of the members can be started with DB2 12 to migrate the DB2 catalog. Non-data sharing DB2 subsystems must also run with this APAR before attempting to migrate to DB2 12. This APAR allows fallback to DB2 11 after a migration to DB2 12 and also allows release coexistence in a data sharing environment. Refer to the DB2 12 publications for procedures for migration and then subsequent fallback to DB2 11.
Problem conclusion
Temporary fix
Comments
The purpose of this APAR is to allow fallback from DB2 12. Refer to the chapters 'Falling back' and 'Remigrating' in the DB2 12 Installation Guide for this procedure. ++HOLD COMMENT FOR RELEASE B10, TYPE ACT: After applying this PTF, you need to re-assemble and linkedit DSNHDECP to pick up the changes in DSNARIB. Under DB2 data sharing, if each member of the group has its own DSNHDECP module then you need to repeat the steps below for each member. These are the steps to update DSNHDECP: (1) Create a separate job containing only the DSNTIZP and DSNTIZQ steps from the job DSNTIJUZ previously edited by the install CLIST. (2) Re-assemble and linkedit the DSNHDECP load module by running your newly created job to produce a new DSNHDECP. (3) Stop and start your DB2. Additional Keywords: DB2MIGV12/K
