When OpenTP1 restarts to recover all transactions, it can determine the managed transactions based on journals.
The pre-online transaction recovery facility acquires the information about undetermined transactions from the resource manager specified in the -m option in the trnstring definition command in the transaction service definition. Then the facility recovers the transactions before OpenTP1 goes online when OpenTP1 starts (regardless of normal start or restart).
When you use this facility, recovery processing is repeated at the interval specified in the trn_start_recovery_interval operand in the transaction service definition. Recovery processing is repeated until there is no information left about undetermined transactions from the resource manager. Therefore, OpenTP1 goes online only when there is no information about undetermined transactions from the resource manager.
To use this facility, use the trnlnkrm command to re-register resource managers in the OpenTP1 system and specify -m option in the trnstring definition command in the transaction service definition. For details, see the description about the transaction service definition in the manual OpenTP1 System Definition.
