DSNP021I csect-name EXTEND NOTIFY FAILED FOR data-set-name, SC=ssssssss, NOTESC=nnnnnnnn, CONNECTION-ID=xxxxxxxx, CORRELATION-ID=yyyyyyyyyyyy, LUW-ID=logical-unit-of-work-id=token
Explanation
This is an internal error. The connection ID, correlation ID, and logical-unit-of-work ID (LUW-ID) identify the user or application that encountered the problem.
An LUW-ID of '*' indicates that the thread does not have an LUW-ID. If the LUW-ID is not an '*', the value is a logical-unit-of-work-id that is assigned to the thread followed by an '=' sign and a token value, which can be used in place of the logical-unit-of-work-id in any Db2 command that accepts the logical-unit-of-work-id as input.
Messages that have the same connection ID, correlation ID, and LUW-ID relate to the same user. This makes it possible to scan a number of DSNP-prefixed messages and group activities involving a given user. Correlation IDs beginning with '0nn', where 'nn' is a number, identify system agents.
If message DSNT376I was received before message DSNP021I, the notify request failed because of a timeout condition.
System action
The current SQL statement or the unit of recovery that issued the request might be terminated.
Problem determination
Obtain the console sheet and a dump. A GTF trace might also be required.
If you suspect an error in Db2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.
