Multiple Encyclopedias

Multiple Encyclopedias support more concurrent use and more concurrent processing. Each Encyclopedia has its own database. Multiple Encyclopedia databases allow you to store information in separate paths. For example, you can separate the storage of:

• Various versions of test models
• Test models and production models
• Models representing conceptually different information
• Models different groups work on
• Models with different security requirements

Note: In multi-encyclopedia installations on one system, the character set must be the same for all encyclopedias that are controlled by a message dispatcher, when the encyclopedias are on the same system. Each server/utility inherits its language information from the Message Dispatcher's execution environment. An environment variable, such as NLS_LANG, can have only one value in an environment, and it must be correct for all encyclopedia databases using that variable. The same is true for servers that are spawned from IEFRDS if more than one encyclopedia is being handled remotely. In this case, the environment is inherited from IEFRDS.
