Cache recommendations for Content Manager OnDemand servers and application groups

Question & Answer


Question

When is cache recommended for a Content Manager OnDemand application group? Should the Content Manager OnDemand cache be used if ad hoc storage of documents is performed in a Content Manager OnDemand server?

Cause

Content Manager OnDemand commands and APIs that perform ad hoc document storage should use magnetic cache for better performance. Depending on the platform, the application group can be set up to migrate to Tivoli Storage Manager (TSM), Object Access Method (OAM), or the Archived Storage Manager (ASM). Loading directly to these archive solutions is supported, but not recommended when using these commands and APIs to do ad hoc storage of documents.

Answer

Content Manager OnDemand application groups that are defined to support ad hoc document storage work best when magnetic cache storage is defined. They should also use an Expiration Type of Segment.

The Content Manager OnDemand server works best when using cache storage for ad hoc document storage requests. The Content Manager OnDemand server uses the cache to append the new documents being stored to the current storage object in the cache. The server performs this append until the maximum storage object size is reached. That larger storage object can be migrated to an archive solution, like TSM, at a later date, if desired. This lowers the overhead and improves performance of the archive solution, by storing fewer objects that are larger in size.

Recommended: Content Manager OnDemand System Log application group should have cache storage defined and the following commands and APIs should use an application group with cache storage defined:

  • ARSDOC ADD command
  • Add Document (ADDDOCOND) command (IBM i only)
  • Content Manager OnDemand OLE control method StoreDoc
  • Java API method ODFolder.storeDocument
 
 

This also includes the use of IBM Content Collector or CommonStore against Content Manager OnDemand because these solutions do ad hoc storage of documents into Content Manager OnDemand.
