Explanation
An error is detected for device
device_number running
under XRC session
session_id. The XRC session has
been active under storage control session
session_number.
The reason code for the error is given by
reason_code,
as follows:
- Reason
- Description
- 3
- The number of entries in the cache has exceeded the supported
limit. The current limit is 16K entries.
- 4
- The subsystem storage cache is overcommitted. The XRC session
is canceled.
- 5
- The storage control has encountered an internal error. The XRC
session is canceled.
System action
XRC functions for volumes under this storage control
are ended.
System programmer response
This error can occur as a result of
several configuration problems, as follows:
- Verify that the journal and control data sets are set up correctly.
See z/OS DFSMS Advanced Copy Services for
additional details.
- Verify that secondary volume I/O activity can be supported by
the configuration. Verify that the secondary volumes are attached
to storage controls with sufficient NVS, and that DASD fast write
is active.
- Verify that the storage control cache size is adequate to support
the primary volume update rate.
- Verify that the host configuration can support the XRC activity.
You might need to allocate more expanded storage to support the XRC
work load.
If all configuration conditions appear to be correct,
search problem reporting data bases for a solution for the problem.
If no solution exists, contact the IBM® Support
Center. Provide the system log and SVC dumps of the ANTAS000 and any ANTASnnn address
spaces that are active. To determine which address spaces
are active, enter the console command DISPLAY A,ANTAS*. If an
XRC error is indicated in the system log, also provide pertinent SYS1.LOGREC
information.
