DFR3726W THE LATEST MSDBCP IS NOT FOUND, THE OLDER ONE IS USED FOR RECOVERY.

Explanation
 The MSDB checkpoint data set that
has the latest Fast Path checkpoint ID
cannot be found. Normally, this does not happen, because IMS updates the Fast Path checkpoint ID
after it has confirmed that the checkpoint data set has
been written successfully.

System action
 If MSDB=O is specified, MSDBCPx DD statements written in the data set
specified by the MSDBOUTn DD statement will contain the older MSDB checkpoint data set name in the later pair.

User response
 Check the MSDB checkpoint data set list,
and if necessary, confirm the status of the data set.
