• Whether audit trail collection is inherited by the switchover target system is determined from the termination mode of the switching HiRDB. If the switching system is restarted, the status before system switchover is inherited. If the switchover target system terminates normally, it follows the specification of the pd_audit operand.
• If the system switchover facility is used in the monitor mode, an audit trail is collected when system switchover occurs and the standby HiRDB system (the standby unit for a HiRDB parallel server configuration) is started. An audit trail is not collected when system switchover occurs in server mode.
• If system switchover occurs due to an error, HiRDB does not correctly collect the audit trail before the switchover.

If the pdplgrgst command is used to register, delete, or upgrade plug-ins with HiRDB, HiRDB uses the pdplgrgst command extension to issue the following SQL statements:

• CREATE statements for functions, abstract data types, or indexes provided by the plug-ins
• DELETE statements for the plug-in definition information stored in the dictionary tables
• DROP statements for functions, abstract data types, or indexes provided by the plug-ins

If audit events are set for these SQL statements, an audit trail is collected for these SQL statements using the pdplgrgst command extension.

An audit trail is not collected for pair volumization (disk duplexing). Use the OS's auditing facility to audit pair volumization.
