To use Oracle9i RAC, specify the -r option in the trnstring definition command in the transaction service definition and suspend the recovery of OpenTP1 transactions. To enable the -r option in the trnstring definition command, you need to specify "OPS_FAILOVER=T" as an open character string.

When the -r option is specified in the trnstring definition command, the system suspends the responses from the resource manager, locking the transaction recovery process. Therefore, increase the number of transaction parallel recovery processes (value specified in the trn_recovery_process_count operand) for the number of resource managers specified in the -r option in the trnstring definition command. If you do not increase the number of transaction parallel recovery processes, transaction recovery processing may be affected.

If an error occurs in a resource manager during startup processing or online processing while transaction recovery is suspended, the transaction recovery is delayed until the error in the resource manager is corrected.

You can change or delete the -r option in the trnstring definition command in the transaction service definition at restart. For details, see the description about the system service definition and the definitions that can be changed at restart in the manual OpenTP1 System Definition.
