Constructor Detail

JDBCConnectionPoolVital

public JDBCConnectionPoolVital(java.lang.String vitalKey,
                               VitalSignProperties properties)

Creates the vital sign. This method must pass-through to the super-class so the vital sign can be auto-loaded.

Method Detail

hasChildInstances

public boolean hasChildInstances()

This vital sign has child instances to collect measurements.

Overrides:

hasChildInstances in class VitalSign

See Also:

VitalSign.hasChildInstances()

getConnectionPoolRuntimeMBean

public weblogic.management.runtime.JDBCConnectionPoolRuntimeMBean getConnectionPoolRuntimeMBean()

Retrieves the runtime MBean for a named execute queue

getCurrentMeasurement

protected AbstractVitalMeasurement getCurrentMeasurement()

Takes a measurement of the vital sign at the current moment and returns it to the caller. This method should be implemented by subclasses that are automatically called by the vitals manager on a periodic basis. The default implementation in this superclass is to return null, leaving the implementation to a subclass.

Overrides:

getCurrentMeasurement in class VitalSign

Returns:

the current measurement for this vital sign or null if no implementation

basicGetMaximumMeasurement

public AbstractVitalMeasurement basicGetMaximumMeasurement()

Returns the maximum theoritical value of the vital sign.

Overrides:

basicGetMaximumMeasurement in class VitalSign

Returns:

the current measurement for this vital sign or null if no implementation

getPoolName

public java.lang.String getPoolName()

Returns the poolName. Pool name is a unique key and can therefore be used as the child vital key.

refreshChildInstances

public void refreshChildInstances()

Looks at all the registered JDBC connection pools and activates children for each one currently applicable.

Overrides:

refreshChildInstances in class VitalSign

See Also:

VitalSign.refreshChildInstances()
