BSDS problems

For background information about the bootstrap data set (BSDS), see the WebSphere MQ for z/OS Concepts and Planning Guide.

This section describes the following BSDS problems:

• Error occurs while opening the BSDS

• Log content does not agree with the BSDS information

• Both copies of the BSDS are damaged

• Unequal time stamps

• Out of synchronization

• I/O error

Normally, there are two copies of the BSDS, but if one is damaged, WebSphere MQ immediately changes to single BSDS mode. However, the damaged copy of the BSDS must be recovered before restart. If you are in single mode and damage the only copy of the BSDS, or if you are in dual mode and damage both copies, use the procedure described in Recovering the BSDS.

This section covers some of the BSDS problems that can occur at startup. Problems not covered here include:

• RECOVER BSDS command errors (messages CSQJ301E - CSQJ307I)

• Change log inventory utility errors (message CSQJ123E)

• Errors in the BSDS backup being dumped by off-load (message CSQJ125E)

For information about the above problems, see the WebSphere MQ for z/OS Messages and Codes manual.
