Column Display Related Tasks Related Topics

This page displays a variety of statistics about the performance of the entity EJB. Use the runtime information for tuning and debugging the EJB.

#### Column Display

You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.

The following table lists all of the data points that you can display in columns on this page.

Name | Description
--- | ---
Machine | The WebLogic Server host computer (machine) on which this server is meant to run. If you want to use a Node Manager to start this server, you must assign the server to a machine and you must configure the machine for the Node Manager. You cannot change this value if a server instance is already running. MBean Attribute: `ServerMBean.Machine` Changes take effect after you redeploy the module or restart the server.
Server | An alphanumeric name for this server instance. (Spaces are not valid.) The name must be unique for all configuration objects in the domain. Within a domain, each server, machine, cluster, JDBC connection pool, virtual host, and any other resource type must be named uniquely and must not use the same name as the domain. The server name is not used as part of the URL for applications that are deployed on the server. It is for your identification purposes only. The server name displays in the Administration Console, and if you use WebLogic Server command-line utilities or APIs, you use this name to identify the server. After you have created a server, you cannot change its name. Instead, clone the server and provide a new name for the clone. MBean Attribute: `ServerMBean.Name` Changes take effect after you redeploy the module or restart the server.
EJB Name | Provides the ejb-name for this EJB as defined in the ejb-jar.xml deployment descriptor. MBean Attribute: `EntityEJBRuntimeMBean.EJBName`

Waiter Current Count | Provides a count of the number of Threads currently waiting for an available bean instance from the free pool. MBean Attribute: `EjbPoolRuntimeMBean.WaiterCurrentCount`
Access Total Count | Provides a count of the total number of times an attempt was made to get an instance from the free pool. MBean Attribute: `EjbPoolRuntimeMBean.AccessTotalCount`
Miss Total Count | Provides a count of the total number of times a failed attempt was made to get an instance from the free pool. An Attempt to get a bean from the pool will fail if there are no available instances in the pool. MBean Attribute: `EjbPoolRuntimeMBean.MissTotalCount`
Destroyed Total Count | Provides a count of the total number of times a bean instance from this pool was destroyed due to a non-application Exception being thrown from it. MBean Attribute: `EjbPoolRuntimeMBean.DestroyedTotalCount`
Cached Beans Current Count | Provides a count of the total number of beans from this EJB Home currently in the EJB cache. MBean Attribute: `EJBCacheRuntimeMBean.CachedBeansCurrentCount`
Cache Access Count | Provides a count of the total number of attempts to access a bean from the cache. The sum of the Cache Hit Count and Cache Miss Count may not add up to the cacheAccessCount in a running server because these metrics are retrieved using multiple calls and the counts could change between the calls. * MBean Attribute: `EJBCacheRuntimeMBean.CacheAccessCount`
Cache Hit Count | Provides a count of the total number of times an attempt to access a bean from the cache succeeded. The sum of the Cache Hit Count and Cache Miss Count may not add up to the cacheAccessCount in a running server because these metrics are retrieved using multiple calls and the counts could change between the calls. MBean Attribute: `EJBCacheRuntimeMBean.CacheHitCount`
Cache Miss Count | Provides a count of the total number of times an attempt to access a bean from the cache failed. The sum of the Cache Hit Count and Cache Miss Count may not add up to the cacheAccessCount in a running server because these metrics are retrieved using multiple calls and the counts could change between the calls. MBean Attribute: `EJBCacheRuntimeMBean.CacheMissCount`
Activation Count | Provides a count of the total number of beans from this EJB Home that have been activated. MBean Attribute: `EJBCacheRuntimeMBean.ActivationCount`
Passivation Count | Provides a count of the total number of beans from this EJB Home that have been passivated. MBean Attribute: `EJBCacheRuntimeMBean.PassivationCount`
Lock Entries Current Count | Provides a count of the number of beans currently locked. MBean Attribute: `EJBLockingRuntimeMBean.LockEntriesCurrentCount`
Lock Manager Access Count | Provides the total number of attempts to obtain a lock on a bean. This includes attempts to obtain a lock on a bean that is already locked on behalf of the client. MBean Attribute: `EJBLockingRuntimeMBean.LockManagerAccessCount`
Waiter Total Count | Provides the current number of Threads that have waited for a lock on a bean. MBean Attribute: `EJBLockingRuntimeMBean.WaiterCurrentCount`
Timeout Total Count | Provides the current number of Threads that have timed out waiting for a lock on a bean. MBean Attribute: `EJBLockingRuntimeMBean.TimeoutTotalCount`
Transactions Committed Total Count | Provides a count of the total number of transactions that have been committed for this EJB. MBean Attribute: `EJBTransactionRuntimeMBean.TransactionsCommittedTotalCount`
