Figure 2-28 DMCONFIG File Entry


DMCONFIG File Entry

  1. The CPI-C application program MIRRCPIC is invoked using environment start-up specifications.
  2. The MIRRCPIC client requests cminit to establish conversation attributes and receive a conversation id that will be used on all other requests on this conversation. The remote server and service are named in the CPI-C side information entry MIRRSIDE.
  3. The cmallc request initiates the advertised service mapped to MIRRORSERV in the DM_LOCAL_SERVICES section of the DMCONFIG file.
  4. The cmsst request prepares the next send request by setting the send type to CM_SEND_AND_PREP_TO_RECEIVE.
  5. The cmsend request immediately sends the contents of obuffer to the ATMI service in the tpsvcinfo->data buffer and relinquishes control to the mirrorserv service.
  6. The cmrcv request receives the contents of the odata returned on the ATMI tpreturn service, and notification that the conversation has ended with the return code value of CM_DEALLOCATED_NORMAL.
