Method Detail

enableSymmetricActivationStateMode

void enableSymmetricActivationStateMode(int templateNodeID)
                                 throws InvalidStateException,
                                        InvalidArgumentException,
                                        ConfigurationException

Enable the symmetric activation state mode.

When the symmetric activation state mode is enabled, a template node ID must be specified. Services and resource adaptor entities on other cluster nodes will be activated and/or deactivated as needed so that they match the state of the template node. While the symmetric activation state mode continues to remain in force, services and resource adaptor entities are activated and deactivated across the cluster in unison, and per-node state operations for these components can no longer be used.

The activation state of the SLEE itself (STOPPED or RUNNING) is always configurable on a per-node basis.

Parameters:

templateNodeID - the node ID of the node to base the activation state of any other cluster nodes on. This node doesn’t have to be a current cluster member, but it must have some per-node state already in existence.

Throws:

InvalidStateException - if the symmetric activation mode is already enabled, or if the mode cannot currently be set because a service or resource adaptor entity that needs to be in the ACTIVE state is currently STOPPING on some cluster node.

InvalidArgumentException - if an invalid node ID is specified or if the specified node has no per-node activation state.

ConfigurationException - if some other error occurs while trying to enable the mode.

disableSymmetricActivationStateMode

void disableSymmetricActivationStateMode()
                                  throws InvalidStateException,
                                         ConfigurationException

Disable the symmetric activation state mode.

While the symmetric activation state mode is disabled, services and resource adaptor entities may have different activation states on different cluster nodes.

Throws:

InvalidStateException - if the symmetric activation state mode is already disabled.

ConfigurationException - if some other error occurs while trying to disable the mode.

isSymmetricActivationStateModeEnabled

boolean isSymmetricActivationStateModeEnabled()
                                       throws ConfigurationException

Determine if the symmetric activation state mode is currently enabled.

Returns:

true if the symmetric activation state mode is currently enabled, false otherwise.

Throws:

ConfigurationException - if an error occurs while trying to determine the current mode.
