TBresynch command

The state data for the TBresynch command portion of the OTMA message prefix is mapped by the TMAMHDR DSECT of the DFSYMSG macro.

The TBresynch command is sent by the client to IMS if the client decides it is ready to receive REQresynch from IMS. The TBresynch command can be issued in the following two situations:
  • The client has received an ACK message after sending REPresynch with stop and wait for TBresynch to IMS.
  • The client may request a TBresynch with IMS at any time after the initial nondeferred resynchronization has completed for this tpipe.
