(1) Design for improved reliability
- The amount of space required for a HiRDB file system area for work table files must be greater than the total size of the work table files to be created in the area. For details about the sizes of work table files, see 18. Determining Work Table File Size.
- A HiRDB file system area for work table files must be created at the server machines where the following servers are defined:
- Dictionary server
- Back-end server
(2) How to check the peak capacity
You can use the following command to obtain the peak capacity of a HiRDB file system area for work table files:
- pdfstatfs -d name-of-HiRDB-file-system-area-for-work-tables
- -d
- Specifies that the maximum utilization value for the allocated HiRDB file system area is to be displayed. The peak capacity display that is output is this value. The maximum utilization value is cleared by entering the following pdfstatfs command:
- pdfstatfs -c name-of-HiRDB-file-system-area-for-work-tables
- -c
- Specifies that the maximum utilization value for the allocated HiRDB file system area is to be cleared to 0.
