Explanation
This message indicates that the coupled XRC session
indicated on message ANTQ8200I is not currently interlocked with the
other coupled sessions associated with the master session indicated
on message ANTQ8246I. The timestamp represents
the amount of time that this local session requires to be interlocked
with the other coupled interlocked local sessions. If the timestamp is
within 10 seconds (ahead or behind) of the master journal timestamp,
the coupled data mover sessions will achieve interlock status by temporarily
halting updates on the sessions that are ahead. Updates will be resumed
when interlock status is achieved.
The timestamp value will
have one of the following definitions:
- +aa:aa:aa.aaaaaa
- The consistency time of this session is ahead of the master journal
time for other coupled sessions, which would prevent it from being
recovered to a consistent time with those sessions. The time shown
is the difference between the session consistency time and the master
journal time.
- -bb:bb:bb.bbbbbb
- The journal time of this session is behind the master journal
time for other coupled sessions, which would prevent it from being
recovered to a consistent time with those sessions. The time shown
is the difference between the session journal time and the master
journal time.
System action
XRC functions are active.
System programmer response
This message is issued for a non-interlocked
session if all of the following are true:
- An update has been made to at least one active volume in the session
and the update has been journaled (that is, the session has a journal
time).
- At least one update has been applied for the session to secondary
volumes (that is, a session consistency time exists).
- The session does not indicate the volume status of AVS, ERR, or
SYM on message ANTQ8304I.
You might need to take special steps to achieve interlock
status for this session. In order for a session to become interlocked,
both of the following conditions must be met (issue the XQUERY MASTER
command to determine these conditions):
- No interlocked session associated with the master session must
have a session status of END, SUS, or UNK.
- The master session must not be in HOLD status.
See z/OS DFSMS Advanced Copy Services for
examples of XQUERY command output. See previously issued ANT error
messages and their associated return codes and reason codes to determine
the appropriate actions that allow you to get a session into interlock
status.
