This section discusses the design considerations for HiRDB file system areas in which RDAREAs are to be created.
Table 9-1 Allocation of HiRDB file system areas to improve performance
Type of HiRDB file system areas | File to be allocated |
---|---|
HiRDB file system area for system RDAREAs | Character special file |
HiRDB file system area for dictionary LOB RDAREAs | |
HiRDB file system area for user LOB RDAREAs | |
HiRDB file system area for user RDAREAs that store frequently updated tables or tables primarily subject to retrieval of small amounts of data | |
HiRDB file system area for user RDAREAs that store tables with a large amount of data that are primarily subject to retrieval of all entries or retrieval of large amounts of data by key using the cluster key (but with data that is rarely updated) |
