Unequal time stamps

Symptoms
WebSphere MQ issues the following message:
CSQJ120E +CSQ1 DUAL BSDS DATA SETS HAVE UNEQUAL TIME STAMPS,
           SYSTEM BSDS1=...,BSDS2=...,
           UTILITY BSDS1=...,BSDS2=...

The possible causes are:

System action
WebSphere MQ attempts to resynchronize the BSDS data sets using the more recent copy. If this fails, queue manager startup is terminated.
System programmer action
None.
Operator action
If automatic resynchronization fails, carry out these steps:
  1. Run the print log map utility on both copies of the BSDS, compare the lists to determine which copy is accurate or current.
  2. Rename the down-level data set and define a replacement for it.
  3. Copy the good data set to the replacement data set, using Access Method Services.
  4. If applicable, determine whether the volume containing the down-level BSDS has been restored. If it has been restored, all data on that volume, such as the active log data, is also down-level.

    If the restored volume contains active log data and you were using dual active logs on separate volumes, you need to copy the current version of the active log to the down-level log data set. See Recovering logs for details of how to do this.
