Automatic resource status changes

Content Engine sets a new resource status for a storage area in response to a storage area condition. The status changes occur in accordance with the following table:

Previous resource status Storage area condition New resource status
    Online Offline
    Open Closed Standby Full
  New storage area
     
Standby No Open storage area
     
Open Closure date passed  
   
Count maximum exceeded      
Size maximum exceeded      

Offline storage area conditions
Content Engine checks for the following conditions when adding content to a storage area:

All these conditions cause Content Engine to change the resource status from Open to an offline status. For example, upon detecting the count maximum exceeded condition, Content Engine changes the resource status from Open to Full. (While an offline condition exists, you can directly change the resource status to some other offline status but not to the Open status.)

Online storage area conditions
Content Engine sets the resource status to Open for a newly created storage area. Thereafter, Content Engine changes the resource status of a storage area to Open in the following circumstances:

For example, suppose the storage areas X, Y, and Z have a status of Standby, and all documents have been assigned a storage policy that specifies these three storage areas. When attempting to add content for the first document, Content Engine randomly selects one of the storage areas--such as X--and changes the status of X to Open. For the current document in question, Content Engine adds content to area X. For subsequent documents, Content Engine continues to add content to area X until the status of X changes for any reason. (The reason might be that a user has made the status become Closed by taking X offline, or that Content Engine has changed the status to Full because the count maximum exceeded condition is now true for X, and so on.) Of the remaining storage areas with a status of Standby, Content Engine again randomly selects one of the storage areas--such as Y--and changes the status of Y to Open. For the current document in question, Content Engine adds content to area Y. For subsequent documents, Content Engine continues to add content to area Y until the status of Y changes for any reason.

When a storage policy has multiple storage areas with a status of Open, Content Engine randomly distributes new content among these areas for purposes of load balancing. For more information on storage policies and load balancing, see About storage policies.
