When any of the operations listed below occurs, you must restart the alternate portion. If you do not restart the alternate portion, it will terminate abnormally when system switchover occurs. You must also restart the alternate BES unit after operation 1 or 3 below occurs.
If the alternate portion terminates abnormally, use the pdstart -q -c command to start it.
When performing the operations listed above, terminate the normal BES unit then restart it. If you do not restart the normal BES unit, it will terminate abnormally when system switchover (or system switchback) occurs. If the normal BES unit terminates abnormally, use the pdstart -q command or pdstart -u command to start the normal BES unit.
To minimize the time required for system switchover, the standby-less system switchover (1:1) facility opens only the RDAREAs needed for full recovery when system switchover occurs; it does not open other RDAREAs. The RDAREA opening trigger attributes in the normal BES unit are listed below:
For details about RDAREA opening trigger attributes, see 15.5 Modifying an RDAREA opening trigger attribute (RDAREA modification).
To minimize the time required for system switchover, the standby-less system switchover (effects distributed) facility opens only the RDAREAs needed for full recovery when system switchover occurs; it does not open other RDAREAs. The RDAREA opening trigger attributes are listed below:
For the RDAREA opening trigger attributes when you use the standby-less system switchover (effects distributed) facility, see the explanations for the pd_rdarea_open_attribute_use and pd_rdarea_open_attribute operands in the manual HiRDB Version 8 System Definition.
