CHNGTPRSLVTM, Mupip will change tp_resolve_time from xxxx to yyyy because expected EPOCH or EOF record was not found in Journal File zzzz.
MUPIP Information: At startup, backward recovery/rollback internally computes a time called the tp_resolve_time which is until when backward processing will be performed across journal files of all regions. During backward processing it is possible in very rare cases that recovery does not see an EPOCH record or an EOF record as the last record in the journal file of those regions that had not been updated for quite a long time. In such cases recovery reduces the tp_resolve_time further by taking into account the timestamp of the last journal record. This effectively causes further backward processing but is necessary for a clean recovery. A CHNGTPRSLVTM message is printed whenever such journal files are encountered by backward recovery.
Action: None necessary
