Recovery and Restart Procedures

Recovery and Restart Procedures

When CICS and the MUF go down, use the following recovery and restart procedures:

1. Run the COMM STATUS function of the CA Datacom/DB Utility (DBUTLTY) to release all threads that are not in in-doubt status.

   Note: For more information, see the CA Datacom/DB DBUTLTY Reference Guide.

2. Bring up the MUF.
3. Warm start CICS.

Before the re-synchronization process for resolving the in-doubt status can start, make certain the following have first been completed:

1. Enable the MUF.
2. Complete a warm start of CICS.
3. Start up CA Datacom CICS Services if DCCOCPR is not in the PLT, DBEC P,STARTUP or DBOC STARTUP.
4. Connect CA Datacom CICS Services to the MUF (or MUFs). If the connect type is not PLT, DBEC I,MUF(??), issue C for connect.

Be aware that if DCCOCPR is not in the CICS PLT or if the DBCSID does not have CONNECT=PLT, Step 3. or Step 4. in the list just shown may have to be done manually with DBOC STARTUP and possibly a DBEC P,CONNECT.
