Understanding Cache Maintenance

To improve the overall performance of transactions, AAF implements rowset cache, which is used for populating the information on AAF objects, such as terms, implementations, contexts, subject areas and so on. Data caching occurs when AAF objects are added and updated. However, with caching in place, sometimes the system may not pick up all updates that are made to existing objects.

To avoid missing updates, AAF provides an application engine (AE) process that, when run, clears rowset cache.

Maintain Cache Page

Use the Maintain Cache page (EOCF_CLR_CACHE) to run the cache maintenance AE process.

Cache maintenance is a two-step process. First, perform a synchronization check on the types of cached objects you selected. When the process instance completes successfully, load the cached objects. When the loading process is also completed successfully, reboot the application server and web server, clear all caches, and check to make sure that modified AAF objects have in fact been updated in the system.

Note: You need to sign into the PeopleSoft system in the same language that was used to run the cache maintenance process to view any AAF object updates that occurred as a result of the process.

Check Synchronization

Select to run a synchronization check on the types of cached objects that are selected in the Cached Object Types group box. This is the first part of the cache maintenance process.

Bulk Load

Select to load the selected types of cached objects to the system. This is the second part of the cache maintenance process.

Examine Cache

Click to start the cache maintenance (EOCF_DCACHE) process (for either Check Synchronization or Bulk Load) in Process Scheduler. Both the link and the current status of the actual process instance are available on this page.

Options

If you wish to run the process periodically, select the applicable server and frequency for its run schedule.

Results Page

Use the Results page (EOCF_CLR_RESULTS) to review the cache maintenance process result.

Use this page to review the EOCF_DCACHE AE process result. The counts or status of fixed cache objects is stored in the EOCF_CLR_STATS table.
