Starting an IMSplex

Starting an IMSplex involves starting required CSL components, such as SCI and OM, starting the IMS control regions, and starting any other optional IMSplex components, such as CSL RM, CSL ODBM, IMS Connect, and so on.

The following briefly summarizes starting an IMSplex:

Procedure

  1. Start all SCIs.
  2. Start all OMs.
  3. If using a resource structure, start CQS.
  4. If using RM, start all RMs.
  5. Start all IMS control regions with the following parameters:
    • CSLG= parameter specified on the control region execution or the DFSPBxxx member of the IMS PROCLIB data set.
    • Parameters specified in the DFSDCxxx member of the IMS PROCLIB data set if you do not want to use the defaults:
      • RCVYSTSN
      • RCVYFP
      • SRMDEF
    • OCMD and CSLT parameters specified in the DFSVSMxx member of the IMS PROCLIB data set.
    • Parameters specified in the DFSCGxxx member of the IMS PROCLIB data set:
      • CMDSEC
      • IMSPLEX
      • NORSCCC
      • OLC
      • OLCSTAT
    • Appropriate parameters specified in the BPE and CQS PROCLIB member data sets.
  6. Start any other optional IMSplex components, such as ODBM and IMS Connect.
  7. If you use a SPOC, you can log on to TSO, allocate the appropriate files to the TSO user ID, and issue the DFSSPOC command from ISPF option 6.
