Adding new parameters to SYS1.PARMLIB(IGDSMSxx)

To include RLS support in your system, specify the required parameters in the IGDSMSxx member of SYS1.PARMLIB.

  • Specify RLSINIT(YES); otherwise, SMSVSAM does not initialize automatically when you IPL MVS™. Alternatively, you can start SMSVSAM using the VARY SMS,SMSVSAM,ACTIVE command.
  • Specify a value for the deadlock detection interval with the DEADLOCK_DETECTION parameter.
  • Specify time intervals for the creation and synchronization of VSAM RLS SMF records with the CF_TIME and SMF_TIME parameters.
  • Specify the maximum size of the SMSVSAM local buffer pool with the RLS_MAX_POOL_SIZE parameter.
