Executor: HiRDB administrator

Unloading system log files means that the pdlogunld command is entered to unload system log files that are waiting to be unloaded. If this step is skipped, there will be no system log files that are eligible to be swapped in (swappable target status files) and HiRDB will terminate abnormally.

HiRDB provides a facility, called the automatic log unloading facility, for unloading system log files automatically.

This section assumes that the reader is familiar with the system log unloading operations.
