4. Application group
An application group contains the storage management attributes of and index fields for the data that you load into OnDemand. When you load a report into OnDemand, you must identify the application group where OnDemand will load the index data and store the documents. An application group is a collection of one or more OnDemand applications with common indexing and storage management attributes. You typically group several reports in an application group so that users can access the information contained in the reports with a single query. All of the applications in the application group must be indexed on at least one of the same fields, for example, customer name, account number, and date.

Storage set:
A storage set contains one or more storage nodes that can be used by several application groups that have the same archive storage requirements. For example, a storage set can be used to maintain data from different application groups that must retain documents for the same length of time and require the data to be kept on the same type of media. Different storage sets can be created to handle different data retention requirements. One storage set can be set up to maintain data on cache-only storage, and another can be set up to point to archive storage to maintain data for three years on optical …show more content…
The database manager also maintains the OnDemand system tables that describe the applications, application groups, storage sets, folders, groups, users, and printers that you define to the system. You should periodically collect statistics on the tables in the database to optimize the operation of the OnDemand database.
Storage manager: The OnDemand cache storage manager maintains a copy of documents, usually temporarily, on disk. The cache storage manager uses a list of file systems to determine the devices available to store and maintain documents. You typically define a set of cache storage devices on each object server so that the data loaded on the server can be placed on the fastest devices to provide the most benefit to your users.
For multiplatform and z/OS, the cache storage manager uses the arsmaint command to migrate documents from cache storage to archive media and to remove documents that have passed their life of data
