Class MQQueueManager


  • public class MQQueueManager
extends MQManagedObject
    The MQQueueManager class provides a connection to a WebSphere MQ queue manager.

    An MQQueueManager object (and any queues or processes accessed through it) can be shared between multiple threads, but be aware that access to the WebSphere MQ queue manager itself is synchronized, so that only one thread can communicate with it at any one time. A call to MQQueue.get()specifying CMQC.MQGMO_WAIT(for example) will therefore block any other threads attempting to make WebSphere MQ calls using the same MQQueueManager until the get completes.

      • MQQueueManager

        public MQQueueManager(java.lang.String queueManagerName)
               throws MQException
        Creates a connection to the named queue manager.

        The host name, channel name and port to use during the connection request are specified in the MQEnvironmentclass. This must be done before calling this constructor.

        The following example shows a connection to a queue manager "MYQM", running on a system with host name "fred.mq.com". 

         <CODE>
 MQEnvironment.hostname = "fred.mq.com"; // host to connect to
 MQEnvironment.port = -1; // port to connect to.  If not set, this
 // defaults to 1414 for WebSphereMQ Client connections.
 MQEnvironment.channel = "channel.name"; // the CASE-SENSITIVE name of the SVRCONN channel
 // on the queue manager
 MQQueueManager qMgr = new MQQueueManager("MYQM");
 </CODE>

        If the queue manager name is null or blank, then a connection is made to the default queue manager.

       MQMessage message)
         throws MQException
        Places or publishes a single message onto a queue or topic without having to create an MQQueue or MQTopic object first.

        When used to place messages to a queue allows you to omit the queue manager name, put message options, and alternative user ID. When used to publish messages to a topic allows you to omit the topic string, put message options and alternative user ID.

        The destinationName parameter will adopt different meanings depending upon the destination type being specified in the type parameter.

        The default options used for unspecified parameters may alter depending upon the destination type specified.

        Note that the default syncpoint is CMQC.MQPMO_NO_SYNCPOINT for all platforms.

        Parameters:
        type - The options used to control the specified destination type. Valid values are: Only one option should be specified - the values must not be combined by addition or using the bitwise OR operator.

        These options may be expanded later to include new destination types such as multicast addresses, etc.

        destinationName - The name of the queue or topic onto which to place or publish the message. Depending upon the value of the type parameter this parameter will adopt different meanings:
        • If CMQC.MQOT_Q is specified the destinationName parameter directly maps to the queue name - i.e. MQOD.ObjectName.
        • If CMQC.MQOT_TOPIC is specified the destinationName parameter directly maps to the topic object - i.e. MQSD.getObjectName() (the topic object ObjectName property is left blank).
        message - The message to send. Properties within the message may be altered as a result of placing or publishing the message to a queue or topic. It is therefore marked as both an input and output parameter.
        Throws:
        MQException - If the call fails.

                  java.lang.String alternateUserIdArg)
                    throws MQException
        Establishes access to a WebSphere MQ queue on this queue manager in order to get or browse messages, put messages, inquire about the attributes of the queue, or set the attributes of the queue.

        If the queue named is a model queue, then a dynamic local queue is created. The name of the created queue is held in the name field of the returned MQQueue object.

        Parameters:
        queueName - name of queue to open.
        openOptionsArg - options which control the opening of the queue. As inquire and set options are automatically added to the options provided, there is no need to specify these explicitly. The valid options are: If more than one option is required the values can be combined using either the '+' or '|' operator. See WebSphere MQ Application Programming Reference for a complete description of these options.
        queueManagerName - name of the queue manager on which the queue is defined. A name which is blank, or which is null, denotes the queue manager to which this object is connected.
        dynamicQueueName - name of the dynamic queue to be created. This parameter is ignored unless queueName specifies the name of a model queue. If it does, this parameter specifies the name of the dynamic queue to be created. A blank or null name is not valid if queueName specifies the name of a model queue. If the last non-blank character in the name is an asterisk (*), the queue manager replaces it with a string of characters which guarantees that the name generated for the queue is unique at the local queue mananager. Asterisk is only valid in positions 1 to 33 of the dynamicQueueName parameter.
        alternateUserIdArg - if CMQC.MQOO_ALTERNATE_USER_AUTHORITY is specified in the openOptions parameter this parameter specifies the alternate user ID to be used to check the authorization for the open. If CMQC.MQOO_ALTERNATE_USER_AUTHORITYis not specified, this parameter can be left blank (or null).
        Returns:
        the MQQueue that has been successfully opened.
        Throws:
        MQException - if the open fails.

        Establishes access to an WebSphere MQ queue on this queue manager using default queue manager name and alternative user ID values.
        Parameters:
        queueName - the name of the queue to open.
        openOptionsArg - options which control the opening of the queue. See accessQueue(String, int, String, String, String) for more information.
        Returns:
        an MQQueue that has been successfully opened.

      • accessTopic

        public MQTopic accessTopic(java.lang.String topicName,
                  java.lang.String topicObject,
                  int openAs,
                  int options)
                    throws MQException
        Establishes access to a WebSphere MQ topic. The MQTopic object may be opened for either publication or subscription depending upon the value of the openAs parameter. The value dictates the use of the options parameter - this may map to the equivalent CMQC#MQOO options for publication or the equivalent CMQC #MQSO options for subscription.

        The options specified allows the MQTopic object to be used to get or browse messages, put messages, inquire about the attributes of the topic, or set the attributes of the topic.

        An MQTopic object cannot be used for both publication and subscription simultaneously. Therefore, the constructor creates an MQTopic object for publication OR subscription using the supplied topic name (topicName) and topic object ( topicObject).

        The full topic name is given by the concatenation of the preceding two parts. A part exists if the first character of the field is neither a blank nor a null character. If both parts exist a ?/? character is inserted between them in the resultant combined topic. If only one of these parts exist it is used unchanged as the topic. These parts are concatenated in the order they are listed below.

        • The value of the TOPICSTR parameter of the topic object named in topicObject.
        • topicName, if the length provided for that string is non-zero.
        If there are wildcards in the topicName, the interpretation of those wildcards can be controlled using the wildcard options specified in the options parameter.

        When creating an MQTopic for subscriptions, the store (MQQueue) will be managed and owned by the queue manager. This constructor can therefore only be used to create a managed subscription.

        Parameters:
        topicName - The topic string to publish or subscribe against. The topicName parameter directly maps to the ObjectString field of the MQSD (see MQSD.getObjectString(). The full topic name used is the combination of the topicObject and topicName parameters.
        topicObject - The name of the topic object as defined on the local queue manager. If this property is specified in combination with a non-zero length topicName, then the specified topicName is appended to the topic string contained in the topic object with a separator character. It is the full topic string which is published or subscribed against.

        The parameter is both an input and output parameter. Upon successful completion of the method the closest matching administrative node is located within the topic hierarchy and returned. The contained topic object may therefore differ to that originally specified.

        openAs - Indicates whether the topic is being opened for either publication or subscription. The parameter may contain one of the following valid options: The topic object may only be opened for either publication or subscription. Specifying more than a single option will result in an error condition.
        options - Options that control the opening of the topic for either publication or subscription. The following options are valid: If more than one option is required, the values can be added together or combined using the bitwise OR operator. See the WebSphere MQ Application Programming Reference for a fuller description of these options.

        However, upon opening the topic for subscription the following valid options are shown below. If more than one option is required, the values can be added together or combined using the bitwise OR operator.

        If none of these options are specified, then CMQC.MQSO_CREATE + CMQC.MQSO_ALTER is assumed. Other valid options are also available.

        Upon opening a topic for subscription, the constructor can only cater for a managed, non-durable subscription. The following options are therefore enforced:

        Returns:
        An MQTopic object that has been successfully opened.
        Throws:
        MQException - If the call fails.

                    throws MQException
        Establishes access to a WebSphere MQ topic. The MQTopic object may be opened for either publication or subscription depending upon the value of the openAs parameter. The value dictates the use of the options parameter - this may map to the equivalent CMQC#MQOO options for publication or the equivalent CMQC MQSO options for subscription.

        If either CMQC.MQOO_ALTERNATE_USER_AUTHORITY or CMQC.MQSO_ALTERNATE_USER_AUTHORITY is specified in the options parameter, the alternateUserId parameter is used to check for the necessary authorization.

        The options specified allows the MQTopic object to be used to get or browse messages, put messages, inquire about the attributes of the topic, or set the attributes of the topic.

                    throws MQException
        Establishes access to a WebSphere MQ topic. The presence of the subscriptionName parameter indicates that this constructor may be used for opening the topic for subscriptions only. The options parameter therefore always maps to the equivalent CMQC #MQSO values.

        If the CMQC.MQSO_ALTERNATE_USER_AUTHORITY is specified in the options parameter, the alternateUserId parameter is used to check for the necessary authorization.

        The options specified allows the MQTopic object to be used to get or browse messages, inquire about the attributes of the topic, or set the attributes of the topic.

        The constructor creates an MQTopic object for subscription using the supplied topic name (topicName) and topic object (topicObject).

        The full topic name is given by the concatenation of the preceding two parts. A part exists if the first character of the field is neither a blank nor a null character. If both parts exist a ?/? character is inserted between them in the resultant combined topic. If only one of these parts exist it is used unchanged as the topic. These parts are concatenated in the order they are listed below.

        • The value of the TOPICSTR parameter of the topic object named in topicObject.
        • topicName, if the length provided for that string is non-zero.
        If there are wildcards in the topicName, the interpretation of those wildcards can be controlled using the wildcard options specified in the options parameter.

        When creating an MQTopic for subscriptions, the store (MQQueue) will be managed and owned by the queue manager. This constructor can therefore only be used to create a managed subscription.

        Parameters:
        topicName - The topic string to publish or subscribe against. The topicName parameter directly maps to the ObjectString field of the MQSD (see MQSD.getObjectString(). The full topic name used is the combination of the topicObject and topicName parameters.
        topicObject - The name of the topic object as defined on the local queue manager. If this property is specified in combination with a non-zero length topicName, then the specified topicName is appended to the topic string contained in the topic object with a separator character. It is the full topic string which is published or subscribed against.

        The parameter is both an input and output parameter. Upon successful completion of the method the closest matching administrative node is located within the topic hierarchy and returned. The contained topic object may therefore differ to that originally specified.

        options - Upon opening the topic for subscription the following valid options are shown below. If more than one option is required, the values can be added together or combined using the bitwise OR operator. If none of these options are specified, then CMQC.MQSO_CREATE + CMQC.MQSO_ALTER is assumed. Other valid options are also available.

        The constructor can only cater for managed subscriptions. The following options are therefore enforced:

        altUserId - If CMQC.MQSO_ALTERNATE_USER_AUTHORITY is specified in the options parameter, this parameter specifies the alternate user identifier that is used to check for the required authorization to complete the operation.

        If CMQC.MQSO_ALTERNATE_USER_AUTHORITY is not specified, this parameter can be left blank (or null).

        subscriptionName - This field is only required if the options parameter specified CMQC.MQSO_DURABLE, but if provided will be used by the queue manager for CMQC.MQSO_NON_DURABLE as well.

        For a CMQC.MQSO_DURABLE subscription it is the means by which you identify a subscription to resume it after it has been created, if you have either closed the handle to the subscription or have been disconnected from the queue manager.

        If altering an existing subscription using the CMQC.MQSO_ALTER option, the subscription name cannot be changed

        Returns:
        An MQTopic object that has been successfully opened.
        Throws:
        MQException - If the call fails.

                      int openOptionsArg,
                      java.lang.String queueManagerName,
                      java.lang.String alternateUserIdArg)
                        throws MQException
        Establishes access to a WebSphere MQ process on this queue manager in order to inquire about the process attributes.
        Parameters:
        processName - name of the process to open
        openOptionsArg - options which control the opening of the process. As inquire is automatically added to the options specified there is no need to specify it explicitly. Valid options are: If more than one option is required the values can be combined using either the '+' or '|' operator.
        queueManagerName - name of the queue manager on which the process is defined. A name which is entirely blank or null denotes the queue manager to which this object is connected.
        alternateUserIdArg - if CMQC.MQOO_ALTERNATE_USER_AUTHORITY is specified in the openOptions parameter, this parameter specifies the alternative user ID to be used to check the authorization for the open. Otherwise this parameter can be blank or null.
        Returns:
        an MQProcess that has been successfully opened.
        Throws:
        MQException - if the open fails.
