M204.2304  Reset not allowed​,​ CHKPTIMR PST not active

A RESET DKUPDTWT from zero to a non-zero value was attempted. However the CHKPTIMR PST was not attached during Model 204 initialization. Since nonzero settings of DKUPDTWT require use of the CHKPTIMR PST, the RESET command cannot be performed.

System manager response: The CHKPTIMR PST is attached during Model 204 initialization under either of the following circumstances:

  • DKUPDTWT > 0
  • CPTIME > 0 and the X'01' bit of RCVOPT is on, the CHKPOINT stream is successfully opened, and sufficient pseudo subtasks are available (see NSUBTKS).

If you require the ability to change DKUPDTWT from zero to a nonzero value after initialization, then one of these conditions must be met during initialization.
