Notes

If you are positioning a system log file to be automatically extended in a HiRDB file system area on a regular file, allocate sufficient free space on the disk on which the HiRDB file system area is being created.
If the HiRDB file system area is extended as system log files are automatically extended, HiRDB initializes the extended area, increasing the disk input/output load.
Swapping to a system log file being extended might require some time. In such a case, reassess the value specified for the pd_log_swap_timeout operand or the -t option of the pdlogswap command.
When the current file is being extended, the HiRDB file system area is locked during extension, and as a result system log input/output might require some time.
