DFS2489I ERE VSO LOG RECORD ERROR
Explanation
Restart log processing encountered a VSO DEDB area log record that did not match any area known to the restarting system. This problem happens during emergency restart, XRF tracking, XRF takeover, or Fast Database Recovery processing,
The log record should contain the VSO DEDB area name and a time stamp. The presence of the log record signifies that area updates, which were committed before the logged time, were written to DASD before failure. Based on this log record, restart log processing can ignore updates that were written to DASD, but without a valid area name it cannot determine which updates to ignore and which to process.
In most cases restart can tolerate this error, although performance might be degraded. A subsequent log record might correct the problem (that is, might show which updates were written to DASD for the area), otherwise restart does additional REDO processing.
If this problem recurs, IMS restart
can run out of resources to track VSO area updates. If this happens,
any affected areas are stopped and marked recovery needed
.
In addition to this message, some diagnostic information is output. Although this error does not terminate IMS, the information has the same format as output from abend 1026.
This message and the accompanying diagnostic information are issued a maximum of three times. Message DFS2686I is issued at the end of emergency restart and shows the total number of times the error condition was detected.
System action
Restart continues.
System programmer response
During local emergency restart of XRF takeover, no action is required. If the problem occurs during XRF tracking, restart the XRF alternate to relieve resource shortage and performance degradation.
Problem determination
1, 5, 11, and a memory dump of the restarted system after restart finishes.
