IXG318E

z/OS MVS Setting Up a Sysplex

Explanation
Log stream primary storage consumption for the
log stream has reached the 100% in use point, meaning it is considered
full. For a CF structure based log stream, this message can also be
issued when the CF structure element pool space allotted to this log
stream is within the MAXBUFSIZE (maximum size of one log block) range
of reaching 100%.
This message was issued as per the WARNPRIMARY
log stream specification and the MONITOR LSPRIMARY CONSUMPTIONALERT
parmlib policy specification.
In the message text: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 will reject new IXGWRITE requests
for the log stream until space can be made available in the primary
(interim) storage medium. Warning message IXG316E for this same structure
or warning message IXG317E for this log stream will be deleted by
the system.
If interim storage space becomes available, log
data writes may be honored.
When the constraint condition is
relieved, meaning when the log stream primary (interim) storage consumption
appears to be at least 5% less than full after an offload activity,
then after a slight time delay message IXG319I will be issued and
the system will delete message IXG318E.
If an offload is delayed
due to a secondary storage inhibitor, system logger may issue messages
IXG310I, IXG311I, IXG312E, and/or IXG271I, IGX272E.

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

        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 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.
