IXG317E

z/OS MVS Setting Up a Sysplex

Explanation
System logger is alerting operations that the log
stream primary storage consumption has exceeded the imminent threshold.
This message was issued as per the WARNPRIMARY log stream specification
and the MONITOR LSPRIMARY CONSUMPTIONALERT parmlib policy specification.
In
the message text:curusage
Is the current percentage of the log stream primary storage medium
in-use.
imminentpct
Is the log stream alert threshold, which is the log stream primary
(interim) storage consumption percentage 2/3 between the HIGHOFFLOAD
value and 100% full (rounded down to the nearest whole number).
logstream
Name of the log stream.
strname
For a coupling facility log stream, the name of the structure
associated with the log stream. For a DASD-only log stream, the value
will be "NOT APPLICABLE".

System action
System logger continues accepting new IXGWRITEs
for the log stream. Message IXG317E will be deleted when system logger
detects after an offload activity the log stream usage drops 5% or
more below the imminent imminentpct value.
If
an offload is delayed due to a secondary storage inhibitor, system
logger may issue messages IXG310I, IXG311I, IXG312E, and/or IXG271I,
IXG272E. If the primary storage resource becomes full, system logger
will no longer accept new IXGWRITEs for the log stream and message
IXG318E will be issued. 

Operator response
Notify the System Programmer

System programmer response
        Check the log stream and structure resources, if appropriate. Issue the following logger
          command and check the message IXG601I
          output.D LOGGER,C,LSN=logstreamname,D

        When the log stream duplexing option is listed as "DUPLEXING: STAGING DATA SET" in the
          display output, then also check the staging data set detail lines to see if the resource
          constraint stems from the data set being at or near full.

        For a CF structure based log stream, also issue the following XCF command and check the
          message IXC360I output to show details of the specified logger
          structure.D XCF,STR,STRNAME=logger_structure

System programmer response
        Check on the total and in use counts as well as the percentage full values for the CF
          structure entries and elements in the message IXC360I usage into portion of the display
          output.

        Check for any conditions in the installation that may be preventing the offload from
          proceeding. Monitor for messages IXG310I, IXG311I, IXG312E, IXG271I, IXG272E or other
          offload related messages.
