IXG278I

group

Explanation
System logger issued an asynchronous ARCHRCAL request
to recall a migrated data set for a log stream. When "STAGING" appears
in the message, the recall is for a log stream staging data set; otherwise
the recall is for a log stream offload data set.
In the message
text:group
is the name of the log stream group for the MIGRATED DATASET task
in system logger that issued the asynchronous data set recall request
(either PRODUCTION or TEST).
logstream
is the log stream name.
staging
is the word STAGING or null.
dsname
is the log stream data set name.

System action
After issuing the ARCHRCAL, system
logger waits for the data set to be recalled. When DFSMShsm (or an equivalent function)
responds with the recall results, system logger continues with the
recall operation. The system logger MIGRATED DATASET task handler
for the identified log stream group continues with DFSMShsm requests
unless the limit for that group has been reached. For the PRODUCTION
group MIGRATED DATASET task, up to 24 asynchronous recall requests
can be outstanding. For the TEST group MIGRATED DATASET task, up to
8 asynchronous recall requests can be outstanding.
If
the maximum recall requests are reached for the group, the
MIGRATED DATASET task is considered busy, and the system logger task
monitor will track progress. If no progress is detected, the system
issues messages IXG271I and IXG272A. While the task is in this busy
state, subsequent migrated data set requests the system does not process
for group until one of the following occurs: One of the current recall requests completes.
System logger is specifically requested to stop waiting from either
a reply to action message IXG272A or through the SETLOGR FORCE,NORECall,DSName=datasetname
command.

If the maximum recall requests are not yet
reached for the group, but at least one of the recall requests
is satisfied within 30 seconds, system logger issues message IXG281I
that indicates data set recall requests are pending.

Operator response
None.

System programmer response
If system logger recall
requests are delayed, check for IXG271I, IXG311I messages in the system
log. If these messages appear and the data set has not yet been recalled,
determine if DFSMShsm is
functioning properly. You can use the DISPLAY LOGGER,STATUS,RECALLS
command can be used to display all the outstanding data set recalls
requested by Logger. Consider responding to messages IXG272E or IXG312E.
SETLOGR FORCE,NORECall,DSName=datasetname command to cause system
logger to stop waiting for a particular request.

User response
None.

Programmer response
None.
