public interface JDBCOracleDataSourceInstanceRuntimeMBean
extends RuntimeMBean
extends RuntimeMBean

Runtime MBean for monitoring a JDBC GridLink Data Source instance.

Method Summary
`int`	`getActiveConnectionsCurrentCount()` The number of connections currently in use by applications.
`int`	`getConnectionsTotalCount()` The cumulative total number of database connections created in this instance since the data source was deployed.
`int`	`getCurrCapacity()` The current count of JDBC connections in the connection pool in the data source for this instance.
`int`	`getCurrentWeight()` The current weight of the instance.
`String`	`getInstanceName()` The name of this instance.
`int`	`getNumAvailable()` The number of database connections currently available (not in use) in this data source for this instance.
`int`	`getNumUnavailable()` The number of database connections that are currently unavailable (in use or being tested by the system) in this instance.
`long`	`getReserveRequestCount()` The cumulative, running count of requests for a connection from this instance.
`String`	`getSignature()` The signature that uniquely identifies the instance.
`String`	`getState()` The current state of the instance within the data source.
`boolean`	`isAffEnabled()` The value from the latest load-balancing advisory `aff` flag for a GridLink data source instance.
`boolean`	`isEnabled()` Indicates whether the instance is enabled or disabled: true if the instance is enabled. false if the instance is disabled.

Method Detail

getInstanceName

String getInstanceName()

The name of this instance.

Returns:: The instance name.

getSignature

String getSignature()

The signature that uniquely identifies the instance.

Returns:: The instance signature.

getCurrentWeight

int getCurrentWeight()

The current weight of the instance.

Returns:: The current weight of instance.

getActiveConnectionsCurrentCount

int getActiveConnectionsCurrentCount()

The number of connections currently in use by applications.

Returns:: Current total number of active connections.

getReserveRequestCount

long getReserveRequestCount()

The cumulative, running count of requests for a connection from this instance.

Returns:: The cumulative count of requests for connections from this instance.

getConnectionsTotalCount

int getConnectionsTotalCount()

The cumulative total number of database connections created in this instance since the data source was deployed.

Returns:: The cumulative total number of JDBC connections created in this instance.

getCurrCapacity

int getCurrCapacity()

The current count of JDBC connections in the connection pool in the data source for this instance.

Returns:: The current pool capacity of this instance.

getNumAvailable

int getNumAvailable()
