Name	Description
Test Data Source	Tests the connection pool in the data source by reserving and releasing a connection from it. If the pool configuration attribute TestConnectionsOnReserve is enabled, the acquired connection is also tested as part of the reserve operation. MBean Attribute: JDBCDataSourceRuntimeMBean.testPool

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
Name	The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration. MBean Attribute: JDBCDataSourceRuntimeMBean.Name
Partition	The list of domain partitions in which the JDBC data source is available.
Type	The type of data source: Generic, GridLink, UCP, Proxy, or Multi Data Source.
Resource	The resource type of the data source.
Scope	Specifies if the data source is accessible within the domain, a partition, or a resource group template.
Server	The server on which the data source is deployed.
Instances	The name of this instance. MBean Attribute: JDBCOracleDataSourceInstanceRuntimeMBean.InstanceName
ONS	The ONS client associated with this data source.
State	The current state of the data source. Possible states are: Running - the data source is enabled (deployed and not Suspended). This is the normal state of the data source. This state includes conditions when the database server is not available and the data source is created (creation retry must be enabled) or when all connections have failed connection tests (on creation, on reserve, or periodic testing). Suspended - the data source has been disabled. Shutdown - the data source is shutdown and all database connections have been closed. Overloaded - all resources in pool are in use. Unknown - the data source state is unknown. MBean Attribute: JDBCDataSourceRuntimeMBean.State
Active Connections Average Count	Average number of active connections in this instance of the data source. Active connections are connections in use by an application. This value is only valid if the resource is configured to allow shrinking. MBean Attribute: JDBCDataSourceRuntimeMBean.ActiveConnectionsAverageCount
Active Connections Current Count	The number of connections currently in use by applications. MBean Attribute: JDBCDataSourceRuntimeMBean.ActiveConnectionsCurrentCount
Active Connections High Count	Highest number of active database connections in this instance of the data source since the data source was instantiated. Active connections are connections in use by an application. MBean Attribute: JDBCDataSourceRuntimeMBean.ActiveConnectionsHighCount
Connection Delay Time	The average amount of time, in milliseconds, that it takes to create a physical connection to the database. The value is calculated as summary of all times to connect divided by the total number of connections. MBean Attribute: JDBCDataSourceRuntimeMBean.ConnectionDelayTime
Connections Total Count	The cumulative total number of database connections created in this data source since the data source was deployed. MBean Attribute: JDBCDataSourceRuntimeMBean.ConnectionsTotalCount
Current Capacity	The current count of JDBC connections in the connection pool in the data source. MBean Attribute: JDBCDataSourceRuntimeMBean.CurrCapacity
Curr Capacity High Count	Highest number of database connections available or in use (current capacity) in this instance of the data source since the data source was deployed. MBean Attribute: JDBCDataSourceRuntimeMBean.CurrCapacityHighCount
Enabled	Indicates whether the data source is enabled or disabled: true if the data source is enabled. false if the data source is disabled. MBean Attribute: JDBCDataSourceRuntimeMBean.Enabled
Failed Reserve Request Count	The cumulative, running count of requests for a connection from this data source that could not be fulfilled. MBean Attribute: JDBCDataSourceRuntimeMBean.FailedReserveRequestCount
Failures To Reconnect Count	The number of times that the data source attempted to refresh a database connection and failed. Failures may occur when the database is unavailable or when the network connection to the database is interrupted. MBean Attribute: JDBCDataSourceRuntimeMBean.FailuresToReconnectCount
Highest Num Available	Highest number of database connections that were idle and available to be used by an application at any time in this instance of the data source since the data source was deployed. MBean Attribute: JDBCDataSourceRuntimeMBean.HighestNumAvailable
Leaked Connection Count	The number of leaked connections. A leaked connection is a connection that was reserved from the data source but was not returned to the data source by calling close(). MBean Attribute: JDBCDataSourceRuntimeMBean.LeakedConnectionCount
Num Available	The number of database connections that are currently idle and available to be used by applications in this instance of the data source. MBean Attribute: JDBCDataSourceRuntimeMBean.NumAvailable
Num Unavailable	The number of connections currently in use by applications or being tested in this instance of the data source. MBean Attribute: JDBCDataSourceRuntimeMBean.NumUnavailable
PrepStmt Cache Access Count	The cumulative, running count of the number of times that the statement cache was accessed. MBean Attribute: JDBCDataSourceRuntimeMBean.PrepStmtCacheAccessCount
Prep Stmt Cache Add Count	The cumulative, running count of the number of statements added to the statement cache. Each connection in the connection pool has its own cache of statements. This number is the sum of the number of statements added to the caches for all connections in the connection pool. MBean Attribute: JDBCDataSourceRuntimeMBean.PrepStmtCacheAddCount
Prep Stmt Cache Current Size	The number of prepared and callable statements currently cached in the statement cache. Each connection in the connection pool has its own cache of statements. This number is the sum of the number of statements in the caches for all connections in the connection pool. MBean Attribute: JDBCDataSourceRuntimeMBean.PrepStmtCacheCurrentSize
Prep Stmt Cache Delete Count	The cumulative, running count of statements discarded from the cache. Each connection in the connection pool has its own cache of statements. This number is the sum of the number of statements that were discarded from the caches for all connections in the connection pool. MBean Attribute: JDBCDataSourceRuntimeMBean.PrepStmtCacheDeleteCount
Prep Stmt Cache Hit Count	The cumulative, running count of the number of times that statements from the cache were used. MBean Attribute: JDBCDataSourceRuntimeMBean.PrepStmtCacheHitCount
Prep Stmt Cache Miss Count	The number of times that a statement request could not be satisfied with a statement from the cache. MBean Attribute: JDBCDataSourceRuntimeMBean.PrepStmtCacheMissCount
Reserve Request Count	The cumulative, running count of requests for a connection from this data source. MBean Attribute: JDBCDataSourceRuntimeMBean.ReserveRequestCount
JDBC Driver	The driver class name of the JDBC driver used to create database connections. MBean Attribute: JDBCDataSourceRuntimeMBean.VersionJDBCDriver
Wait Seconds High Count	The highest number of seconds that an application waited for a connection (the longest connection reserve wait time) from this instance of the connection pool since the connection pool was instantiated. This value is updated when a completed getConnection request takes longer to return a connection than any previous request. MBean Attribute: JDBCDataSourceRuntimeMBean.WaitSecondsHighCount
Waiting For Connection Current Count	The number of connection requests waiting for a database connection. MBean Attribute: JDBCDataSourceRuntimeMBean.WaitingForConnectionCurrentCount
Waiting For Connection Failure Total	The cumulative, running count of requests for a connection from this data source that had to wait before getting a connection and eventually failed to get a connection. Waiting connection requests can fail for a variety of reasons, including waiting for longer than the ConnectionReserveTimeoutSeconds. MBean Attribute: JDBCDataSourceRuntimeMBean.WaitingForConnectionFailureTotal
Waiting For Connection High Count	Highest number of application requests concurrently waiting for a connection from this instance of the data source. MBean Attribute: JDBCDataSourceRuntimeMBean.WaitingForConnectionHighCount
Waiting For Connection Success Total	The cumulative, running count of requests for a connection from this data source that had to wait before getting a connection and eventually succeeded in getting a connection. MBean Attribute: JDBCDataSourceRuntimeMBean.WaitingForConnectionSuccessTotal
Waiting For Connection Total	The cumulative, running count of requests for a connection from this data source that had to wait before getting a connection, including those that eventually got a connection and those that did not get a connection. MBean Attribute: JDBCDataSourceRuntimeMBean.WaitingForConnectionTotal
