9.2.5 Designing HiRDB file system areas for list RDAREAs
(1) Design considerations
- A list is used to store temporary intermediate results of search processing.
- Create a HiRDB file system area for list RDAREAs on the same back-end server that contains the base table.
(2) Design for improved performance
- You should create HiRDB file system areas for list RDAREAs on a separate hard disk separately from the ones used for the following HiRDB file system areas. In this way, you can distribute input/output operations when searching a list, thereby reducing the processing time.
- HiRDB file system areas for user RDAREAs
- HiRDB file system areas for user LOB RDAREAs
- HiRDB file system areas for work table files
