Interface SasManagementMBean

public interface SasManagementMBean

The SasManagementMBean provides access to the SAS server configuration.

A SasManagementMBean instance always manages the SAS server configuration for the currently active namespace for the client connection. It is not necessary to get a different MBean for different namespaces.

Method Detail

isTracingEnabled

boolean isTracingEnabled()
                  throws ConfigurationException

Determine if the SAS facility is current configured to send trace messages to SAS.

Returns:

true if SAS tracing is enabled, false otherwise.

Throws:

ConfigurationException - if the SAS configuration could not be read.

Since:

Rhino 2.6.0

setTracingEnabled

void setTracingEnabled(boolean sasTracingEnabled,
                       boolean force)
                throws IllegalStateException,
                       ConfigurationException

Enable or disable SAS tracing. When tracing is enabled, the SAS facility sends trace messages to SAS.

Normally the SAS tracing configuration cannot be changed from enabled to disabled while the SLEE state for the current namespace is not STOPPED on any active cluster node. If the force argument to this method is true, the check for current SLEE state is bypassed and the configuration is changed regardless.

Parameters:

sasTracingEnabled - boolean flag indicating whether or not the SAS facility will send trace messages to the configured server.

force - boolean flag indicating whether or not the current SLEE state should be ignored while making the configuration change.

Throws:

IllegalStateException - if SAS tracing is currently enabled, sasTracingEnabled and force were both false, and the SLEE was not stopped on one or more active cluster nodes.

ConfigurationException - if an error occurred updating the SAS configuration.

Since:

Rhino 2.6.0

Parameters:

queueSize - the new queue size.

Throws:
