Updating the Database - Requestor is the PRIMARY Member

In this scenario, a user on system 1 wants to add a name to the database, causing the following events to occur:

Member 1 checks the user states in the table to determine which member is PRIMARY.
Member 1 determines that it is the PRIMARY member.

Member 1 creates a work element, places it on its own work queue, and issues to send the work element to the PRIMARY member (in this case, itself).

      IXCMSGOX  MEMTOKEN=MEM1TKN,MSGBUF=RECORD1,MSGLEN=LENMSG        X
         MSGCNTL=REQUPD,TARGET=MEM1TKN,RETCODE=RETURN,              X
         RSNCODE=REASON,MF=(E,MSGOLSTD)

The message user routine for member 1 gets control. The routine checks the message control information and determines that this is a request to update the database.
Member 1's message user routine creates a work element to prepare to receive the message.

Member 1's message user routine issues IXCMSGIX to read in the message.

      IXCMSGIX   MSGTOKEN=TOKENMSG,MSGBUF=(R3),RETCODE=RETURN,       X
            RSNCODE=REASON,MF=(E,MSGILSTD)

Member 1's message user routine places the work element on the DBMGR's work queue, and posts the DBMGR.
When the DBMGR is done with the work, it issues IXCMSGOX to the requesting member (member 1 in this case) stating that the work is completed, deletes the request from DBMGR's work queue, and updates member 1's status field.
```
      IXCMSGOX   MEMTOKEN=MEM1TKN,MSGBUF=RECORD1,MSGLEN=LENMSG       X
            MSGCNTL=GOODRC,TARGET=MEM1TKN,RETCODE=RETURN,           X
            RSNCODE=REASON,MF=(E,MSGOLSTD)
```
When member 1's message user routine again gets control, the routine determines that the message control information contains GOODRC, indicating a successful update.
Member 1 returns the results of the operation to the caller.
Member 1 deletes that request from its own work queue.
