        Sets the 'var' directory path
        Parameters:
        varDir - the path to the 'var' directory.

      • setNodeIdentifier

        public void setNodeIdentifier​(String nodeIdentifier)
                       throws CoreEnvironmentBeanException
        Sets the node identifier. Should be uniq amongst all instances that share resource managers or an objectstore.
        Parameters:
        nodeIdentifier - the Node Identifier.
        Throws:
        CoreEnvironmentBeanException - if node identifier is null or too long.

      • getSocketProcessIdPort

        public int getSocketProcessIdPort()
        Returns the port number for the Socket based process id implementation. Default: 0 (use any free port) Equivalent deprecated property: com.arjuna.ats.internal.arjuna.utils.SocketProcessIdPort
        Specified by:

      • setSocketProcessIdPort

        public void setSocketProcessIdPort​(int socketProcessIdPort)
        Sets the port on which the socket based process id implementation will listen. Should be uniq amongst all instances on the same host. A value of 0 will result in a random port.
        Parameters:
        socketProcessIdPort - the port number to bind to.

      • getTimeoutFactor

        public int getTimeoutFactor()

      • setTimeoutFactor

        public void setTimeoutFactor​(int timeoutFactor)

      • getSocketProcessIdMaxPorts

        Returns the maximum number of ports to search when looking for one that is free. Default: 1 Equivalent deprecated property: com.arjuna.ats.internal.arjuna.utils.SocketProcessIdMaxPorts
        Specified by:
        getSocketProcessIdMaxPorts in interface CoreEnvironmentBeanMBean
        Returns:
        the maximum number of ports to try.

      • setSocketProcessIdMaxPorts

        public void setSocketProcessIdMaxPorts​(int socketProcessIdMaxPorts)
        Sets the maximum number of ports the socket process id implemention will try when searching to find one that is free.
        Parameters:
        socketProcessIdMaxPorts - the maximum number of ports to try.

      • getProcessImplementationClassName

        public String getProcessImplementationClassName()
        Returns the class name of the Process implementation to use. Default: "com.arjuna.ats.internal.arjuna.utils.SocketProcessId" Equivalent deprecated property: com.arjuna.ats.internal.arjuna.utils.processImplementation
        Specified by:
        getProcessImplementationClassName in interface CoreEnvironmentBeanMBean
        Returns:
        the name of a class implementing Process.

      • setProcessImplementationClassName

        Sets the class name of the Process implementation to use.
        Parameters:
        processImplementationClassName - the name of a class implementing Process.

      • getProcessImplementation

        public Process getProcessImplementation()
        Returns an instance of a class implementing com.arjuna.ats.arjuna.utils.Process. If there is no pre-instantiated instance set and classloading or instantiation fails, this method will log an appropriate warning and return null, not throw an exception.

        Specified by:
        getPid in interface CoreEnvironmentBeanMBean
        Returns:
