Executor: HiRDB administrator

The system log file record length can be changed. The record length must be 1,024, 2,048, or 4,096 bytes. The system log size can be reduced by selecting a short record length.

The current record length can be determined by executing the pdlogls command.

Notes

• The same record length must be set for all system log files.
• If you have selected 2048 or 4096 as the record length for the system log files, specify the selected record length in the pd_log_rec_leng operand. A system log file cannot be opened if its record length does not match the length specified in the pd_log_rec_leng operand.
• Changing the system log file record length also changes the following:
  The total size of all system log files
  The size of shared memory used by the unit controller
  For details about how to estimate these sizes, see the HiRDB Version 9 Installation and Design Guide.
