Active log data set status

The BSDS records the status of an active log data set as one of the following:

NEW

The data set has been defined but never used by WebSphere MQ, or the log was truncated to a point before the data set was first used. In either case, the data set starting and ending RBA values are reset to zero.

REUSABLE

Either the data set has been defined but never used by WebSphere MQ, or the data set has been off-loaded. In the print log map output, the start RBA value for the last REUSABLE data set is equal to the start RBA value of the last archive log data set.

NOT REUSABLE

The data set contains records that have not been off-loaded.

STOPPED

The off-load processor encountered an error while reading a record, and that record could not be obtained from the other copy of the active log.

TRUNCATED

Either:

• An I/O error occurred, and WebSphere MQ has stopped writing to this data set. The active log data set is off-loaded, beginning with the starting RBA and continuing up to the last valid record segment in the truncated active log data set. The RBA of the last valid record segment is lower than the ending RBA of the active log data set. Logging is switched to the next available active log data set, and continues uninterrupted.

or

• An ARCHIVE LOG function has been called, which has truncated the active log.

The status appears in the output from the print log map utility.
