Cache

The Cache page of the Administration perspective offers an overview of and information on all items currently stored in the system's cache which is specially useful when setting up the system's server input buffer size.

The information called from the database is stored in the server input buffer and can be accessed quickly when required. This improves the system's performance as it is less time-consuming than repeatedly calling the database.

Note :Keep this in mind when specifying the maximum size of the server input buffer in the Processes and Utilization page. The value depends on the memory that is available on your computer. For more information, see Processes and Utilization.

Cache List

The following columns are displayed by default:

• Name

  Area of the server input buffer:

  • SCRIPT (scripts)

  • VARA (variables)

  • MQMEM (message queues)

  • ODOC and XREQ (Automic Web Interface)

  • USER (user lists)

  • OBJECT_IDNR (object codes)

  • OBJECT_NAME (object names)

• Threshold value

  Limit for the cache's memory release, specified in the server properties.

  Data is stored in the cache until the maximum size has been reached, in which case the server deletes entries that are no longer required. The cache's maximum size is ignored if it is not possible to remove data.

• Current size

  Cache size currently used

• Items

  Number of cache entries

• Active

  Whether caching is active or not

• Calls

  Number of input buffer calls

• Hits

• Hit ratio (%)
