A change has been made in V11.2.3 to simplify determining which transaction logs are required for a restore to use this restore point. The restore point file naming has been updated to include the log number of the checkpoint that the restore point references.
The new formatting is as follows:
RSTPNT_CHKPNT.L#######.YYYYMMDD.HHMMSS.FCS
RSTPNT_NO_CHK.L#######.YYYYMMDD.HHMMSS.FCS
Where ####### is the transaction log number of the associated checkpoint.
Note: This is a Compatibility Change due to the new naming of restore point files.
