OpenTP1s both in the running system and the standby system are to be started as with those using no system switchover facility. The user must start both OpenTP1s.

The startup procedure differs depending on the contents specified in the system environment definition (mode_conf).

The user should preferably specify AUTO or MANUAL1 so that OpenTP1s will automatically start after abnormal termination. AUTO or MANUAL1 must be specified depending on the operation procedure because of the difference in starting after activation of the OS.

However, to use OpenTP1 in the standby system for postprocessing, for example, determination of an undecided transaction or management of the integrity of the database, for OpenTP1 in the running system, you need to specify the -U option in the dcstart command. In this case, do not specify automatic start.

Caution

If you specify AUTO or MANUAL1 for the mode_conf operand in the system environment definition, OpenTP1 starts automatically when it ends abnormally. In this case, you cannot use OpenTP1 in the standby system for postprocessing. If you want to use OpenTP1 in the standby system for postprocessing, stop OpenTP1 and then specify the -U option in the dcstart command to execute OpenTP1. For details about starting OpenTP1 in the standby system by specifying the -U option in the dcstart command, see the manual OpenTP1 Description.
