Explanation
RRS has detected a log data loss
as the result of connecting to a new version of the named log stream.
The log stream version changed because the log stream definition
in the LOGR policy for the named log stream was deleted and then redefined.
In
the message text:
- lstype
- One of the following log streams:
- MAIN UR
- The RRS MAIN.UR log stream.
- DELAYED UR
- The RRS DELAYED.UR log stream.
- RESTART
- The RRS RESTART log stream.
- RM META DATA
- The RRS RM Meta Data log stream.
- lsname
- The name of the log stream.
- oldlsversion
- The version of the log stream that RRS expected to connect to.
The identifier is the GMT timestamp created when the log stream was
defined.
- newlsversion
- The version of the log stream that RRS connected to. The identifier
is the GMT timestamp created when the log stream was defined.
System action
The system action depends on which log stream
encountered the version mismatch.
- MAIN UR
- Each resource manager that might have had data in the MAIN.UR
log stream is marked as having potentially lost log data. During resource
manager restart, RRS issues a unique return code to inform the resource
manager of the possible data loss.
RRS initialization continues.
- DELAYED UR
- Each resource manager that might have had data in the DELAYED.UR
log stream is marked as having potentially lost log data. During resource
manager restart, RRS issues a unique return code to inform the resource
manager of the possible data loss.
Additionally, RRS marks all
UR state log entries in the MAIN.UR log as heuristic mixed, and it
issues message ATR219I whenever it marks URs as heuristic mixed during
log takeover processing.
RRS initialization continues.
- RESTART
- Each resource manager that might have had data in the RESTART
log stream is marked as having potentially lost log data. During resource
manager restart, RRS issues a unique return code to inform the resource
manager of the possible data loss.
RRS initialization continues.
- RM META DATA
- No action is taken against the RM Meta Data log and RRS initialization
continues.
RRS issues message ATR209I whenever it marks
a resource manager as having lost log data.
Operator response
Inform your system programmer.
System programmer response
Check the hardcopy log to see if
messages ATR209I and ATR219I were issued as a result of this error.
Follow the system programmer response for whichever additional message
that was issued.
