Problem resolution guidelines
RCF directly invokes several IMS utilities, as required, to perform processing needed during recovery processing:
DFSULTR0, the IMS log recovery utility
DBFDBDR0, the IMS MSDB recovery utility
DSPURX00, the IMS DBRC recovery control utility
If an error is encountered that prevents further processing (such as, failure of DFSULTR0 or DBFDBDR0), the RCF informs the MTO and terminates abnormally. The MTO should use IOF, SDSF or an equivalent to examine the report generated by the failing utility. After corrective action is taken, the IMS system can be restarted.
DSPURX00 errors cause RCF to issue an RCF2512 message and pause to allow the MTO to review the DSPURX00 messages via SDSF. The MTO must reply to the WTOR to allow RCF to continue processing.
Note
BMC recommends that either all or none of the databases in an IMS system be registered with DBRC.
