Integration Sap PI – JCAPS through JMS queue problem

It is vendor-independent, and is used almost universally in enterprise messaging systems such as that included in Java CAPS. The features of the JMS version 1.

The use of JMS allows loosely coupled, reliable, asynchronous interactions among Java EE components and legacy systems capable of messaging. Support for distributed transactions, so that database updates, message processing, and connections to EIS systems using the Java EE Connector Architecture can all participate in the same transaction context.

JMS message servers provide the global messaging protocols, such as the routing and delivery of messages, and connection to the JMS database. This software is installed automatically if you select Complete when installing from the GUI, or as an option if you use any other installation method. Nms message destination is a container for stored data, jfaps can follow either the JMS topic or queue model.

A topic is a message destination that conforms to icaps publish-and-subscribe messaging paradigm.

User Comments

Each message destination has at least two JMS Clients jca;s with it: JMS clients provide the local messaging protocols, such as message persistence and delivery semantics, for messages being propagated between Project components.

JMS clients are of two basic types, producers and consumersor a combination of both.

If associated with a queue, these types become queue senders and receiversrespectively. If associated with a topic, they become topic jcapd and subscribersrespectively. It indicates to the Collaboration which topic or queue it expects to receive messages from or send messages to, and allows you to build the JMS business rules. This model separates the business logic from the physical system used to perform the logical operations at runtime.

Each Environment is a graphical construct representing a physical system in which Projects can run. In this model, any of the Projects can be deployed to any of the Environments by means of icaps mapping defined in the Deployment Profiles.

The example in the figure shows that the mjs admittance Project is already in the production phase and therefore was deployed using the production Deployment Profile. The patient records Project is in the staging phase and was therefore deployed to the staging Environment using the staging Deployment Profile.

The insurance billing Project is j,s being developed and tested, and therefore it is deployed to development and testing by means of the development and testing profiles. For each Project, specify the message destinations and configure JMS connections jjms the business process.

For each Environment, assign message servers to Logical Hosts domains and configure the message servers. For each Project, create a Deployment Profile to associate the message destinations and JMS connections with the message servers. For each of the Jca;s components you specify logical properties; these properties jczps independent from the physical implementation.

Links between message destinations and their subscribers and publishers, display a JMS Client jcaaps. By double-clicking the icon in the Connectivity Map, you can configure local connection properties such jmms persistent or non-persistent delivery mode, XA, and concurrent processing.

In the runtime Environment, you specify which message servers are used, and which Logical Hosts domains they are to run on. Once you add a message server to a domain, you specify the physical configurations for the message server. You can configure global properties for JMS messaging such as the port number, message delivery order, tuning configurations, journaling options, and diagnostic options.

Procedures for defining your Jjs are described in Creating a Runtime Environment. When you define a Deployment Profile, you create cjaps between Jcxps and Environments. In the Deployment Profile, you specify which components of the business process are located on which systems in a specific Environment. For the JMS, you specify which message destinations run on a particular message server.

Note that inbound and outbound message destinations must be deployed to the same server. These methods are accessed by displaying the context menu for the OTD root node, and then choosing Select method to call from the menu.

This option displays the method browser, shown in the following figure. You can also drag the node to the mapping area to display the browser. To create Java based Collaboration Definitions that implement an existing web service, you must add the JMS receivereceiveWaitor send web service operation to the Collaboration Definition.

Each of these operations has a set of Java methods that is available for use with it. These methods are accessed by displaying the context menu for the input or output node, and then choosing Select method to call from the menu. The following links lead to detailed descriptions of the listed subtopics. The JMS IQ Manager provides the following special facilities to maintain message order in concurrent processing and across message destinations.

These facilities are in addition to those mandated by the Java Message Server specification. Specifying a set of message destinations a time order group for which fully serialized processing occurs.

The following sections describe each method of processing order. For detailed information about processing order, refer to Message Processing Order.

Sun Enterprise Service Bus enables you to set message priorities for topic publishers and queue senders.

The priority japs causes all messages produced by the client to have that same priority level. For more information, refer to Message Producer Priorities. For more information, refer to Kms Mode. Enterprise Manager offers a graphical interface containing comprehensive runtime management functions. You can monitor message destinations, and view message properties and payloads. The database is also used to store messages that are larger than can be kept in the JMS IQ Manager memory, which is determined by the cache size setting by default 0.

By default, JMS clients are configured for persistent messaging; therefore, in a default configuration, the database is used to store these messages. The messages are stored until they are consumed or until the expiration period expires, which is 30 days by default. The database resides in the message server folder on the Logical Host.

The database consists of a number of database files called segments. A segment is a disk-space store that is memory-mapped on the server.

The segments act together to form the equivalent of a sequential database. You can configure such properties as database filenames, segment size, and the maximum and minimum number of segments created. For more information, refer to Segment Properties. The standard location for the database files is described in Database Configuration and Operation. If journaling is enabled, the instance1 directory also contains a Journal directory, unless another location has been specified for the Journal Directory property.

The Journaling directory holds the journaling database files. For information, refer to Journal Directory. Journaling is disabled by default. The database resides in the following directory: The preceding figure shows that the third segment, 7ef in file stcms7ef Memory is released as soon as the consumer has acknowledged the message or committed the transaction.


When jcaos messages jcals a segment have expired or been removed from their queues, the JMS IQ Manager cleans up the segment, freeing it for reuse. In the preceding figurethe first segment 7ef has several segments that are white, indicating the slot is marked eligible. The segment is therefore almost ready for cleanup.

You can specify message processing, either connection consumer or serial mode, at the JMS client level. For a single consumer with a single process, processing for queues is fully serialized, by default.

The process of processing a message is as follows:. When multiple receivers or multiple processes within a single receiver subscribe to the same message destination queues onlyyou jcals a choice of three first-in, first-out FIFO delivery modes, as listed below.

Receivers can retrieve messages when all older messages have been received, or are being received, and can commit messages in any order without using time sequence. Receivers can retrieve messages when all older messages have been received or are being received, but must commit using jcapw sequence. Receivers read a messages only after all messages have been received and commit messages using a time sequence.

In fully concurrent jcapss, receivers can retrieve messages from a destination only when all older messages have been received or are in the process of being received. Receivers can then commit messages without restrictions. The figure above shows a sample delivery sequence for fully concurrent processing. In steps 1 and 2, the receivers retrieve their messages from the input queue. Both receivers must wait until each consumer has retrieved its messages, or is in the process of retrieving them, before they are able to commit messages to the output destination.

As steps 3 and 4 infer, receivers can commit messages in any order; therefore, messages can be committed out of sequence, which might not be acceptable. For example, a patient release record may be committed before the patient admittance record is committed.

The following table indicates the benefits and drawbacks of fully concurrent processing. In protected concurrent mode, receivers retrieve messages just as in fully concurrent mode, after all messages have been received or are being received. Messages can only be committed, however, if all older messages have previously been committed.

The figure above shows a sample delivery sequence for protected concurrent processing. Both receivers must wait until each consumer has retrieved, or is in the process of retrieving, its messages before being able js commit messages to the output destination. ReceiverB might be ready to commit its message before ReceiverA, but must wait until ReceiverA commits its message step 3.

Protected concurrent processing thus is a more workable solution in a scenario where a Project deals with messages such as patient records, where the admittance record must be committed before the release record. By design, protected concurrent FIFO works only within one transaction, either in the form of jcapx session or in the form of one XA transaction on the same server. In fully serialized mode, receivers can only retrieve messages after all older messages have been received and committed.

The figure above shows a sample delivery sequence for serialized processing.

In step 1, ReceiverA retrieves its message. ReceiverB might at this point be ready to receive its message, but must wait until ReceiverA has committed its message. After ReceiverA commits the message in step 2, ReceiverB can then retrieve and commit its message steps 3 and 4.
