Setting Up on System 2

The following explains what happens when the operator starts the PHONBOOK routine on system 2:

The routine prompts the operator, through a WTOR, to designate PRIMARY, BACKUP, or NOBACKUP.
The operator replies BACKUP.

The task on system 2 issues IXCJOIN as follows:

 SYSTEM2  IXCJOIN  GRPNAME=PHONBOOK,ANSAREA=(R2),ANSLEN=AREALEN,     X
               LASTING=NO,MEMNAME=MEMBER2,GRPEXIT=(R4),              X
               STATEXIT=(R5),MSGEXIT=(R6),USTATE=USTATEB,            X
               STATFLD=(R7),INTERVAL=INTER1,MEMDATA=(R3),            X
               USLEN=LEN,RETCODE=RETURN,RSNCODE=REASON,MF=S

Member 2 is now established as the BACKUP member.

Member 2 issues IXCQUERY to determine if any other members have joined the group yet. At this point, member 1 is active.
Member 2 adds itself and member 1 to member 2's copy of the table.
XCF schedules the group user routine of member 1, notifying member 1 that member 2 is now active. (Member 3 is not active yet, so member 3's group user routine is not scheduled.)
Member 1's group user routine now updates member 1's table (adds member 2).
Member 2 does not attach the DBMGR task because member 2 is not PRIMARY.
Member 2 waits for work.
