V DB2 Preparation 1. Install DB2 subsystem. A separate ICF catalog is recommended for each DB2 subsystem based on the High L evel Qualifier for DB2 datasets. the ICF Catalog should contain only the catalogued objects for a single DB2 subsystem. However, with DB2 V8 and DB2 9 the recommendation is to have two ICF Catalogs, one for each Copy Pool. Th[...]

- recommended production initial definitions for DSNDB07 for an initial installation (each should be on a separate volume) : (4) 4K TableSpaces @ 200 cylinders each (2) 32K TableSpaces @ 200 cylinders each , Total = 1200 cylinders 5. Define archive log environment . If archiving to DASD, create a SMS storage group and configure enough DASD to maint[...]

10. Install the Control Center Stored Procedures required by SAP as described in described in Chapter 3 of the SAP Database Administration Guide for SAP NetWeaver on IBM DB2 UDB for z/OS.

15. Establish and test DB2 Backup/Recovery Procedures. These procedures should include a combination of DB2 and non-DB2 utilities in order to handle various recovery scenarios. In addition, DB2 V8 provides two new utilities for providing DB2 controlled system wide backup and a point in time recovery. These are the BACKUP SYSTEM and RESTORE SYSTEM ([...]

16. The recommendation is to develop a DB2 system libraries configuration that allows each DB2 subsystem to be migrated to a new level of DB2, or DB2 maintenance, individually. For instance, if this is a DB2 data sharing group, you want to migrate members one at a time. The system libraries include SDSNLOAD, SDSNEXIT, SDSNMACS, SDSNSPFP, etc. The R[...]
