IV z/OS Software Preparation 1. Review Software Checklist in Installation Manual. REQUIRED • z/OS 1.6* or higher with the following components installed: UNIX System Services, DFSMS, TCP/IP, LE370, DFSORT • JES2 or JES3 • z/OS Security Server (RACF V 2.
**Documentation and sample scripts for TSA are available from IBM. If the customer chooses an equivalent product they take full responsibility for configuring and testing that product with mySAP.
4. Define the necessary users via RACF definitions (review the SAP Security Guide for IBM DB2 UDB for z/OS) : - define z/OS groupid <SCHEMA> as this will be the creator of all DB2 objects (Defau.
9. Configure the TCP/IP protoco l for GB Ethernet : A. Define the z/OS I/O configuration for the OSA-Express Card: - Define channel path ID for OSA-Express channel with type=OSA - Define OSA-Express control unit with type=OSA - Define 2 OSA-Express devices - Define Unit Addresses for the Control Unit (2 Devices for LCS (D118,D119) B.
SAPCL as per Chapter 4 of the SAP Planning Guide for SAP NetWeaver for IBM DB2 UDB for z/OS. These processes run under Unix System Services (USS). 17. For z/OS V1.
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.
- 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 .
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. The procedures are used for Database administration and replace the FTP submission of JCL streams used in previous releases.
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.
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.

XVI DB2 Backup/Recovery Notes (OSS Note 83000) NOTE: The procedures described here are applicable to DB2 Version 8. Version 8 provides two new utilities for backup and point in time recovery that provides a more robust solution that is less prone to errors, and reduces recovery time and labor time.
Recover to prior point in time - A recovery of all tablespaces, indexspaces, DB2 catalog, and DB2 Directory to a previous log RBA (three ways to acomplish this) - Conditional Restart to recover to any.
- Recover to a prior point in time corresponding to the time of FlashCopy - Reset volumes using FlashCopy, including BSDS and logs - Restart DB2 - Use transaction SM13 to resolve R/3 units of work - Recover to a prior point in time using FlashCopy + logs - Reset volumes using FlashCopy , but use current BSDS and active logs.
DB2 Version 8 Enhancements DB2 Version 8 enhances the SAP backup and recovery process by providing two new system utilities for system level backup and a point in time recovery for the entire SAP system. These are the BACKUP SYSTEM and RESTORE SYSTEM.
XVII SAP Automation And High Availability Solution 1. The following OSS Notes shoul d be reviewed : 569996 (Redbook Updates) 524816 2. Indicate at the time of the sizing that the SAP Central Services instance will run on z/OS, since this will affect the processing and memory requirements.
XVIII SAP A pplication Server on zLinux Considerations 1. Review the latest version of OSS Note 81737 for the supported Linux distribution. 2.
