- Executor: HiRDB administrator
The pdlogunld command is used to unload into an unload log file the information needed for database recovery. In the event of an error in the database, the database recovery utility uses this unload log file to recover the database.
The HiRDB administrator must ensure than any file in unload wait status is unloaded.
- Automatic log unloading facility
- Normally, an unload log file is created by using the pdlogunld command to unload the system log files. This process can be automated by using the automatic log unloading facility. For details on the automatic log unloading facility, see 3.8 Using the automatic log unloading facility.
- Note
- If the system switchover facility is being used, create an unload log file on a shared disk (character special file).
- When an unload log file is created as a regular file, it must be shared by the primary and secondary systems. Therefore, in the case of HP-UX, JFS must be installed.
