9.2.1 Designing HiRDB file system areas for RDAREAs
(1) Design for improved reliability
- HiRDB file system areas for RDAREAs must be created on a server machine where the following servers are defined:
- Dictionary server
- Back-end server
- HiRDB file system areas for the following RDAREAs can be created only on a server machine where a dictionary server is defined:
- System RDAREAs
- Data dictionary LOB RDAREAs
- Registry RDAREA
- Registry LOB RDAREA
- HiRDB file system areas for the following RDAREAs can be created only on a server machine where back-end servers are defined:
- User RDAREAs
- User LOB RDAREAs
(2) Design for improved performance
- You should create separate HiRDB file system areas for the following types of RDAREAs:
- System RDAREAs
- Data dictionary LOB RDAREAs
- User RDAREAs
- User LOB RDAREAs
- Registry RDAREAs
- Registry LOB RDAREAs
- You should create HiRDB file system areas for system files on separate hard disks separately from the ones used for HiRDB file system areas for RDAREAs. In this way, you can distribute input/output operations when collecting a synchronization point dump, thereby reducing the amount of time required to collect the synchronization point dump.
