GLYPH<SM590000> Document: With this expiration type, a document at a time is deleted from the application  group. Data that is stored in archive storage is deleted by the storage manager based on  the archive expiration date. Storing documents with an expiration type of Document  causes the expiration process to search through every document in the segment to  determine whether the expiration date was reached, which results in long processing  times.  When the  arsmaint  expiration process is run, data is deleted only from the application group if  the upper threshold for the size of the cache storage is reached. By default, the cache  threshold is 80%. A lower threshold can be forced by the expiration command parameters.  Unless a reason exists to clear cache, leaving data in cache improves retrieval performance.  By using the advanced storage management settings (Figure 5-11), you can adjust the size of  the load object and determine when report data, indexes, and resources are migrated to  archive storage. The Object Size parameter determines the size of a storage object in kilobytes (KB). Content  Manager OnDemand, by default, segments and compresses stored data into 10 MB storage  objects. The default of 10 MB is the most commonly used object size value.  Important:  Be careful when you change the value for Object Size. Setting the value too  small or too large can adversely affect load performance. However, increasing this value  might be necessary if you load large files and run out of Object IDs during the loading  process. Note:  The object size that is defined here must be equal to or larger than the size of the  compressed storage objects that are defined in any application that is assigned to the  application group.
