Time stamps in the BSDS

The output of the print log map utility shows the time stamps, which are used to record the date and time of various system events, that are stored in the BSDS.

The following time stamps are included in the header section of the report:

SYSTEM TIMESTAMP

Reflects the date and time the BSDS was last updated. The BSDS time stamp can be updated when:

• The queue manager starts.

• The write threshold is reached during log write activities. Depending on the number of output buffers you have specified and the system activity rate, the BSDS might be updated several times a second, or might not be updated for several seconds, minutes, or even hours. For details of the write threshold, see the WRTHRSH parameter of the CSQ6LOGP macro in the WebSphere MQ for z/OS System Setup Guide.

• WebSphere MQ drops into a single BSDS mode from its normal dual BSDS mode due to an error. This can occur when a request to get, insert, point to, update, or delete a BSDS record is unsuccessful. When this error occurs, WebSphere MQ updates the time stamp in the remaining BSDS to force a time stamp mismatch with the disabled BSDS.

UTILITY TIMESTAMP

The date and time the contents of the BSDS were altered by the change log inventory utility (CSQJU003).

The following time stamps are included in the active and archive log data sets portion of the report:

Active log date

The date the active log entry was created in the BSDS, that is, when the CSQJU003 NEWLOG was done.

Active log time

The time the active log entry was created in the BSDS, that is, when the CSQJU003 NEWLOG was done.

Archive log date

The date the archive log entry was created in the BSDS, that is, when the CSQJU003 NEWLOG was done or the archive itself was done.

Archive log time

The time the archive log entry was created in the BSDS, that is, when the CSQJU003 NEWLOG was done or the archive itself was done.
