IBM DB2 9 Fan User Manual


 
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
(Default = SAPR3)
- define R/3 installation userid (superuser) for z/OS (zLinux uses linux root user)
- define userid <sid>adm and groupid SAPSYS to run z/OS System Central
Services (zLinux uses linux user <sid>adm and linux group sapsys)
- define DB2 Connect Userid (for Java it is sap<sid>db, it is recommended that
the user be created without a TSO segment and without an expiration date)
- define userid with DB2 SYSADM authority for installation tasks (only needed for
installation)
- define superuser to start SAPOSCOL and SAPCCMSR under USS
Review the SAP Security Guide for all of the necessary security settings for DB 2.
5. Test FTP and job submission between the application server and z/OS using the
DB2 SYSADM userid created above in step 4. * Pre-Install Check*
6. Setup UNIX System Services parameters by modifying
SYS1.PARMLIB(BPXPARMxx) , including the Physical File System definition for the
TCP/IP communication protocol stack. Integrated INET is recommended over Common
INET. See Sample BPXPRMxx in Section X. SAP Central Services can run under USS
as well as the programs saposcol and sapccmsr.
7. z/OS no longer supports compatibility mode dispatching priorities. A WLM Goal
Mode configuration is required , in particular for the DDF workload since that is where
the SAP enclaves will be created via the DB2 DDF address space. The WLM
configuration and setup is described in the SAP Planning Guide for SAP NetWeaver for
IBM DB2 UDB for z/OS.WLM Workload attributes include: SAP work process type
(dialog, batch, update, etc.), <SID>, host name, ABAP Report, and transaction code.
8. Place the JES Scheduler Work Area (SWA) above the 16MB line:
JES2 - SWA=ABOVE on JOBCLASS(STC)
in SYS1.PARMLIB(JES2PARM)
JES3 - Initialization parameter CIPARM (Converter/Interpreter
Parameter List) defined to place SWA above the line.
