Explanation
A failure might prevent system logger
from using the preferred duplex mode for log stream logstream based
on the log stream definition and on the failure dependency of the
log stream coupling facility list structure.
This
might have been caused by an attempt to offload coupling facility
resident data to DASD or an attempt to delete or allocate a staging
dataset during the commit phase of a structure rebuild.
In the
message text:
- logstream
- The name of the log stream that the request failed for.
- duplexmode
- One of the following:
- STAGING DATA SETS
- System logger is using staging data sets to duplex coupling facility
resident log data despite the fact that local buffers may be used
based on the failure dependency of the coupling facility that the
log stream data resides in.
- LOCAL BUFFERS
- System logger is using local buffers to duplex coupling facility
resident log data despite the fact that Staging Data Sets may be used
based on the failure dependency of the coupling facility that the
log stream data resides in.
- text
- One of the following:
- STAGING DATA SETS MAY NOT BE THE PREFERRED MODE OF DUPLEXING
- LOCAL BUFFERS MAY NOT BE THE PREFERRED MODE OF DUPLEXING
- STAGING DRXRC ALSO BEING USED FOR DISASTER RECOVERY
System action
Duplexing of log stream data for log stream logstream will
be done in the mode specified by duplexmode. The
additional text might also indicate that DRXRC-type staging data set
duplexing for disaster recovery (on a secondary or remote site) log
stream duplexing might be in effect along with primary site local
buffer duplexing.
