Requirements for a MSSID installation


To perform a multiple subsystem (MSSID) installation for Db2 subsystems, you must meet the following requirements:


  • The Db2 subsystem that you choose during an MSSID installation must use the same version of Db2 as the Db2 subsystem on which you performed the initial installation of the product.
  • The products or components that you installed must be able to share BMC product libraries.
  • The MSSID options are not available for the following BMC products and components:

    Product or component

    Notes

    BMC Execution Component for z/OS (DBC)

    DBC does not require deployment. A single installation allows for the required unique SSIDs for each started task. Creating a unique DBC$PARM member for each LPAR enables running multiple DBC started tasks in the sysplex.

    BMCSORT

    None.

    PACLOG

    None.

    User Interface Middleware (UIM) server

    You typically use one UIM server for each z/OS system. The UIM server is a part of the following solutions:

    • BMC Database Performance for DB2
    • BMC System Performance for DB2
    • BMC AMI Database Administration for Db2
    • BMC Performance for DB2 SQL
  • Db2 subsystem characteristics must be similar for all Db2 subsystems in the MSSID model. Installation parameters for subsequent subsystems cannot differ significantly from the initial installation process, with the following exceptions (as applicable to the products that you selected):
    • Job card information
    • Library name for the generated batch jobs
    • DB2 LOAD and EXIT library names
    • Storage group (STOGROUP) names
    • VSAM catalog (VCAT) names
    • APF-authorized library name
    • Installation option names
    • POF
