perform() - Start administrative actions

Function:	BcAdminProxyCluster.perform()
		Starts a given action for the proxy cluster.
Parameters:
	bc_object (BcObject of type BcObjectType.PROXY_CLUSTER).
		Proxy cluster for which the action is to be started.
	action (String)
		Action that is to be started for the specified proxy. Possible values are (see BcDef.ACTION_xxx in the MC-CLI-JavaDoc)
		check-adm	Checks the proxy cluster's administration status.
		check-avail	Checks the proxy cluster's execution status.
		restart	Terminates and restarts the proxy cluster.
		save	Saves the changes that have been made for this proxy cluster in the current session.
		start	Starts the proxy cluster.
		stop	Terminates the proxy cluster.
		update-config	Enters the saved changes in the configuration of the proxy cluster.
	params (kw)
		Dictionary with the key-value pairs for the parameters that are to be passed to the specified action. If action=start, stop, restart or update-config, then the following key-value pair can be specified in the dictionary params:
		key =	value =
		all-components	BcDef.BOOL_TRUE / BcDef.BOOL_FALSE
		container	BcDef.BOOL_TRUE / BcDef.BOOL_FALSE
		communication-service	BcDef.BOOL_TRUE / BcDef.BOOL_FALSE
		force-start	BcDef.BOOL_TRUE / BcDef.BOOL_FALSE (only possible for action=restart)
		lu62gateway	BcDef.BOOL_TRUE / BcDef.BOOL_FALSE / BcDef.COLDSTART (only possible for action=start)
		The following meanings apply: key="all-components“ Specifies whether the action should be performed for all components. key=container Specifies whether the action should be performed for the container of the proxy cluster. key=communication-service Specifies whether the action should be performed for the communication service of the proxy cluster. key=force-start Specifies whether the components of the proxy cluster that are not currently running should also be started. key=lu62gateway Specifies whether the action should be performed for the openUTM-LU62 Gateway of the proxy cluster. value=BcDef.BOOL_TRUE The specified action should be performed for this component of the proxy cluster. value=BcDef.BOOL_FALSE The specified action should not be performed for this component of the proxy cluster (default). value=BcDef.COLDSTART The specified action should be performed as a cold start for this component of the proxy cluster (only permitted for action=start and key=lu62gateway).
Return:	(BcObject of type BcObjectType.ACTION). Contains all information about the started action and all its subactions. To obtain more detailed information, you can call a function of the BcAdminAction module with this object as parameter. None if the action was not started (e.g. if there is nothing to save on a save action).
Exceptions:	BcParameterException, BcObjectException, BcToolException
Note:	In the case of action=start, stop, restart, it may first be necessary to perform an authentication for all proxies as otherwise the action cannot be started for the proxies. If the key-value pair all-components, BcDef.BOOL_TRUE is specified in params for the actions start/stop/restart/update-config then other keyvalue pairs are ignored.
Example:	... import BcAdminProxyCluster ... clstr_obj=BcAdminProxyCluster.getObject("BCCluster") bcaction=BcAdminProxyCluster.perform(clstr_obj,"stop") ...
