17.20 Operation when using the updated-row columnizing facility in a cold standby configuration

For details about the updated-row columnizing facility, see 11.18 Using the updated-row columnizing facility (maintaining the retrieval performance for column store tables). This section provides notes on using the updated-row columnizing facility in a cold standby configuration.

The status of the updated-row columnizing facility (whether the facility is enabled or disabled) is maintained after a host switchover occurs.
If a host switchover occurs when the updated-row columnizing facility is enabled, the maintenance processing is performed after the host switchover is completed.
If you leave the updated-row columnizing facility enabled without handling any errors related to that facility, the maintenance processing that is performed after the host switchover is complete will result in an error, and an error message will be output.
If no maintenance processing is performed for 24 hours consecutively, the KFAA51277-I message is output. However, the monitoring timer is reset when a host switchover occurs. Therefore, if no maintenance processing is performed for 24 hours consecutively again after a host switchover occurs, the KFAA51277-I message is output again.
When a host switchover occurs, the processing that starts I/O control of files used by the updated-row columnizing facility is performed on the host that becomes the new active system. If this processing fails, the maintenance processing that is performed after the host switchover is complete will result in an error.
