Using the General Configuration Section of the DAC

This chapter describes the General Configuration section of the Director Administration Console (DAC), the section that allows you to view and modify settings that control the general behavior of your exteNd Director application. Topics include:

For more information For information about running the DAC, see About the Director Administration Console.

General

The General page displays information about your application. For example, it displays the datasource name for the database in which exteNd Director tables are stored, as well as the build numbers for the subsystems:

cdDACGeneralConfiguration

Logs

exteNd Director provides a logging facility that writes information in one of several standard logs. After you set up logging, you can use the DAC to set or reset the level of detail for each standard log element:

cdDACLogs

Various levels of detail determine how much information is written to the log. A value of 0 means no messages are logged, and a value of 5 means all messages are logged.

For more information about setting up logging and detail levels, see Logging Information.

Cache

exteNd Director can use a built-in server-side cache to store reusable, temporary data to optimize performance. An optional Cache Coordinator allows the cache to work within a server cluster. This section describes:

Cache Settings

The Cache Settings section of the Configuration panel allows you enable or disable the content cache and set the size of the resources the Cache Manager can control:

cdDACCacheSettings

You can use the Save button to temporarily change the in-memory cache settings. To change the settings permanently, modify the config.xml of the Framework service and redeploy the application.

For more information, see Working with Data Caches and Cache Statistics

Cache Holders

The Cache Holders section of the Configuration panel allows you to flush cached objects from all server-lifetime cache holders, or any specific cache holder:

cdDACCacheHolders

These cache holders are used internally to cache exteNd Director subsystem data for server cluster environments. Click the dropdown list button to see a list of cache holders.

NOTE: These caches are flushed automatically by the system based on how frequently data is used. You can use the Flush option if you have a specific need to flush selected caches or all caches manually.

For more information, see server-lifetime caching.and Using the Cache Coordinator.

Cache Coordinator

The Cache Coordinator section of the Configuration panel displays the Cache Coordinator parameters set at deployment time:

cdDACCachedCoordinator

This section applies only if you are running in a server cluster.

For more information, see Using the Cache Coordinator.

Cache Statistics

The Cache Statistics section of the Configuration panel displays the current state of the content cache:

cdDACCacheStatistics

There are three cache containers implemented in the Cache Manager:

Object cache container
Memory cache container
Disk cache container

For more information, see Working with Data Caches.

Here is a description of the statistics:

Cache statistics item	Description
ContentCache.Object.currentSize:	The number of objects currently stored in the object cache.
ContentCache.Memory.currentSize:	The current total size (bytes) of objects stored in the memory cache. If this item is 0, the memory cache is not being used. it
ContentCache.Disk.currentSize:	The current total size (bytes) of objects stored in the disk cache. If this item is 0, the disk cache is not being used. it

If your portal application uses only the object cache container, you can check ContentCache.Object.currentSize and, if necessary, increase the maximum object size in the cache configuration to allow better performance. That value is defined in the config.xml of the Framework service:

  ContentCache.Object.maxSize

NOTE: To make a persistent change to this value, you must redeploy the application. A change you make from the DAC lasts only until the application server restarts.
