Preparing z/OS

  • _____ Target system hardware and software requirements, including required maintenance in Preventive Service Planning (PSP) bucket, are met.
  • _____ UNIX System Services is active with minimum required BPXPRMxx values or better.
  • _____ The /tmp directory has at least 20 MB of free space.
  • _____ The full dataset names of required system datasets are specified.
    Table 1. Dataset names.

    Use the following table to specify dataset names of required system datasets.

    Item Dataset name In LPA or link list?
    SCEERUN    
    SCEERUN2    
    SIEALNKE    
    SCLBDLL2    
  • _____ System exits (IEFUSI) do not restrict WebSphere Application Server for z/OS address spaces to less than 1024 MB.
  • _____ The TSO segment default region size for WebSphere Application Server for z/OS installer and administrator TSO user IDs is at least 768 MB.

Preparing the sysplex

  • _____ The target system is configured as a monoplex or into a multisystem sysplex. (Record sysplex name above.)
  • _____ System logger is configured.
    Table 2. System logger configuration.

    Use the following table to specify the system logger configuration.

    Should the application servers reside in a coupling facility or DASD-only log streams?                                         
    If a coupling facility, specify the structure name  
    SMS data class (for log datasets)  
    SMS storage class (for log datasets)  

Preparing JES2 or JES3

  • _____ The system proclib for application server cataloged procedures is specified.
    Table 3. System proclib for application server cataloged procedures.

    Use the following table to specify the system proclib for application server cataloged procedures.

    System proclib for application server cataloged procedures                                         
  • _____ JES2 exit EXIT06 or JES3 exit IATUX03 do not prevent use of REGION= value on JOB or EXEC statements for WebSphere Application Server for z/OS address spaces.
  • _____ Spool space is added if necessary.

Preparing Resource Recovery Services

  • _____ The RRS cataloged procedure is present in system proclib.
    Table 4. RRS cataloged procedure present in system proclib.

    Use the following table to specify the RRS cataloged procedure present in system proclib.

    Procedure name:                                         
  • _____ The RRS dispatching priority is set using SYSSTC or other means.
  • _____ The RRS cataloged procedure name is defined as a subsystem name in IEFSSN00. The subsystem name must match the cataloged procedure name.
  • _____ The RRS log streams are set up.
  • _____ RRS starts successfully.

Preparing Security Server (RACF®)

  • _____ If multiple security databases are in use, a plan is in place to provide database consistency.
