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.NameServer The server on which the data source is deployed.
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.ActiveConnectionsAverageCountActive Connections Current Count The number of connections currently in use by applications.
MBean Attribute:
JDBCDataSourceRuntimeMBean.ActiveConnectionsCurrentCountActive 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.ActiveConnectionsHighCountConnection 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.ConnectionDelayTimeConnections Total Count The cumulative total number of database connections created in this data source since the data source was deployed.
MBean Attribute:
JDBCDataSourceRuntimeMBean.ConnectionsTotalCountCurrent Capacity The current count of JDBC connections in the connection pool in the data source.
MBean Attribute:
JDBCDataSourceRuntimeMBean.CurrCapacityCurr 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.CurrCapacityHighCountEnabled Indicates whether the data source is enabled or disabled:
trueif the data source is enabled.
falseif the data source is disabled.
MBean Attribute:
JDBCDataSourceRuntimeMBean.EnabledFailed Reserve Request Count The cumulative, running count of requests for a connection from this data source that could not be fulfilled.
MBean Attribute:
JDBCDataSourceRuntimeMBean.FailedReserveRequestCountFailures 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.FailuresToReconnectCountHighest 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.HighestNumAvailableLeaked 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.LeakedConnectionCountNum 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.NumAvailableNum Unavailable The number of connections currently in use by applications or being tested in this instance of the data source.
MBean Attribute:
JDBCDataSourceRuntimeMBean.NumUnavailablePrepStmt Cache Access Count The cumulative, running count of the number of times that the statement cache was accessed.
MBean Attribute:
JDBCDataSourceRuntimeMBean.PrepStmtCacheAccessCountPrep 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.PrepStmtCacheAddCountPrep 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.PrepStmtCacheCurrentSizePrep 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.PrepStmtCacheDeleteCountPrep Stmt Cache Hit Count The cumulative, running count of the number of times that statements from the cache were used.
MBean Attribute:
JDBCDataSourceRuntimeMBean.PrepStmtCacheHitCountPrep 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.PrepStmtCacheMissCountReserve Request Count The cumulative, running count of requests for a connection from this data source.
MBean Attribute:
JDBCDataSourceRuntimeMBean.ReserveRequestCountState 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.StateJDBC Driver The driver class name of the JDBC driver used to create database connections.
MBean Attribute:
JDBCDataSourceRuntimeMBean.VersionJDBCDriverWait 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
getConnectionrequest takes longer to return a connection than any previous request.MBean Attribute:
JDBCDataSourceRuntimeMBean.WaitSecondsHighCountWaiting For Connection Current Count The number of connection requests waiting for a database connection.
MBean Attribute:
JDBCDataSourceRuntimeMBean.WaitingForConnectionCurrentCountWaiting 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.WaitingForConnectionFailureTotalWaiting For Connection High Count Highest number of application requests concurrently waiting for a connection from this instance of the data source.
MBean Attribute:
JDBCDataSourceRuntimeMBean.WaitingForConnectionHighCountWaiting 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.WaitingForConnectionSuccessTotalWaiting 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
