DSNP007I csect-name - EXTEND FAILED FOR data-set-name. RC=reason-code CONNECTION-ID=connection-id, CORRELATION-ID=correlation-id, LUW-ID=logical-unit-of-work-id = token

Explanation

Extension failed in control section DSNPmmmm of the data space manager (DSM). The data-set-name value identifies the data set that is being extended. The reason-code value is the reason code, which indicates why the extend process failed. The connection-id, correlation-id, and logical-unit-of-work-id values identify the user or application that encountered the problem. Correlation identifiers begin with '0nn', where nn is a number that identifies system agents.

When the logical-unit-of-work-id value is '*' (asterisk) the thread does not have a LUWID. If the logical-unit-of-work-id value is not '*', the logical-unit-of-work-id value is a logical unit of work identifier (LUWID) that is assigned to the thread, followed by an '=' (equal sign) and a token value, which can be used in place of the LUWID in any Db2 command that accepts the LUWID value as input.

Messages that have the same connection-id, correlation-id, and logical-unit-of-work-id values relate to the same user. This situation makes it possible to scan a number of DSNP-prefixed messages and group activities involving a given user.

System action

The DSM terminates its actions associated with this extend request. Higher level functions might terminate if they cannot continue without a successful extend. In this case, additional console messages and/or SQL codes are produced. In other cases, higher level functions might be able to resolve the space need without the extend, so they continue normally.

Operator response

See Operator Response for message DSNP001I for this information.

System programmer response

The following sources of information are available to help determine the cause of the failure:
  • See the Programmer Response for message DSNP001I.
  • Analyze the reason-code value in conjunction with the console messages.
  • The reason code might apply to the data set identified in the message or to another data set that is needed for the extend process. If the reason code indicates a data set access failure, the console messages indicate the data set name. For example, if the RC indicates 'resource unavailable', console messages identify the resource that is unavailable. Most likely, the message is DSNT500I.
  • Retrieve diagnostic information from the output of the DISPLAY DB...RESTRICT or DISPLAY UTIL(*)... commands.
