Description
Technical Field
The invention relates to the technical field of WEB application, in particular to a system and a method for controlling JMS message process distribution under a WAS cluster.
Background
The WAS (WebSphere Application Server) is part of the WebShperse product and is responsible for Application integration functions. The container serving as the websphere application program is operated and started, and the application developed based on the websphere middleware service function is maintained and executed in the container.
Referring to fig. 1, an architecture for intercepting, dispatching and processing external request messages by an application system under a WAS cluster is exemplarily shown. As shown in fig. 1, a message request of an external system enters a message queue inside the system through an interface, each WAS member in the WAS cluster has a JMS message listening process, and once a message is found in the message queue, a message processing application in the WAS server is triggered and subsequent logic processing is performed. This is the JMS message processing mode of the currently common WAS cluster architecture.
Referring to this example, it should be noted that the messages in the message queue can simultaneously trigger the JMS message listening processes on all the WAS members to read the messages from the message queue, and which WAS the JMS of the WAS read the message first starts the message processing application by whom, and the other JMS processes are empty. However, when there are multiple messages in the message queue at the same time, because the above mechanism is that multiple listening processes are polling, it is able to implement concurrent processing of message requests at multiple WAS servers. However, there are at least two disadvantages to this existing generic message handling model: the message process distribution cannot be realized in a differentiated manner, and the message process distribution cannot be optimized.
For example, the existing model cannot support the following two scenarios or requirements effectively:
for differentiation, if a certain type of message request is expected to be processed only on certain WAS member servers, for example, only a certain type of message is expected to be processed only on WAS1 and WAS2 but not on WAS3, the differentiation processing mode cannot be realized by the prior art.
For optimization, if it is desired that a certain message request be processed on a relatively idle WAS server, for example, a certain message can be processed on both WAS1 and WAS2, but WAS2 server resources are more idle and so processing on WAS2 servers can be specified rather than WAS1, which has not been possible in the prior art.
Therefore, a technical solution for realizing differentiated and optimized WAS cluster architecture JMS message distribution control, which can overcome the above disadvantages, is needed.

It should be noted that although several modules of the JMS message process distribution control system under the WAS cluster are mentioned in the above detailed description, such partitioning is merely exemplary and not mandatory. Indeed, the features and functionality of two or more of the modules described above may be embodied in one module according to embodiments of the invention. Conversely, the features and functions of one module described above may be further divided into embodiments by a plurality of modules.
For a clearer explanation of the JMS message process distribution control system under the WAS cluster, a specific embodiment is described below.
Fig. 3 is a schematic diagram of a JMS message process distribution architecture under the WAS cluster according to an embodiment of the present invention. Comparing fig. 1 and fig. 3, compared with the prior art, the present invention is provided with a message distribution control table, a process start controller and a message process monitor.
For the message distribution control table, referring to table 1, an exemplary message distribution control table is shown.
Table 1 message distribution control table
| Message type | Allowing node names to run | Maximum number of passes | Number of available processes | Resource idleness ratio |
| AA | WAS1 | 5 | 3 | 0.60 |
| AA | WAS2 | 6 | 2 | 0.33 |
| AA | WAS3 | 4 | 2 | 0.50 |
| BB | WAS1 | 5 | 4 | 0.80 |
| BB | WAS2 | 5 | 1 | 0.20 |
| CC | WAS2 | 6 | 3 | 0.50 |
| CC | WAS3 | 6 | 3 | 0.50 |
Wherein, each item in the message distribution control table is explained as follows:
1. message type: different types of messages are cached in the message queue, such as a debit request class, a credit request class, a statistical query request class, a notification class and the like, which can be analyzed in the messages, and through maintenance of a control table, which type of messages run on which WAS nodes can be controlled, so as to realize differential control of message distribution.
2. Allow run node name: as shown in fig. 3, the WAS node name under the WAS cluster includes: WAS1, WAS2, and WAS 3.
3. Maximum number of passes: on each WAS node, configuring the maximum allowable running process number for each message type to accurately control the maximum resource usage of a certain type of message on a certain node.
4. Number of available processes: the number of processes that can be run by each WAS node for each type of message is embodied. The available process number is the maximum process number-the running process number.
5. Resource idle rate: the available process number/maximum process number is the resource idle rate, and the parameter can be used for judging the busy and idle condition of one WAS node resource, so as to realize the optimization of message distribution.
For the process start controller:
referring to FIG. 4, a logic diagram of a process start controller according to an embodiment of the invention is shown. As shown in fig. 4, after the JMS reads the message from the message queue, the "process start controller" is called first, with the message type and the running node as parameters.
Different from the prior art, the invention does not directly call the message processing application program, but judges whether the message processing application program is started or not by the internal logic processing of the progress starting controller, and the local message processing program can be started by the progress starting controller only if the process starting controller meets the starting condition.
If the JMS acquired message does not accord with the starting condition of the node, the message is not processed, and the JMS of the node which accords with the condition is waited to process.
For a message progress monitor:
referring to fig. 5, a logic diagram of a message progress monitor according to an embodiment of the invention is shown. As shown in FIG. 5, in order to avoid modification or intrusion of the apparatus of the present invention to normal application logic, the number of available processes is monitored by the "message process controller", and the "message distribution control table" is maintained at the same time, instead of maintaining the message distribution control table when the application program is finished.
Specifically, every n milliseconds (n available parameter maintenance) is performed, the message process monitor on the WAS is started, the message processing process of the node is queried through the own command (such as ps) of the operating system, the number of the message processing processes is counted, the number of available processes and the resource idle rate are calculated according to the running number and the maximum number of processes in the message distribution control table, and the data are recorded in the message distribution control table.
Having described the method of the exemplary embodiment of the present invention, next, a method of controlling distribution of a JMS message process under a WAS cluster of the exemplary embodiment of the present invention is described with reference to fig. 6.

step S606, if the resource idle rate is maximum, subtracting 1 from the available process number of the current node, and starting the message processing application process to process the request message;
step S607, if the request message is not in the message queue or the resource idle rate is not the maximum, the request message is put back to the message queue;
step S608, obtaining a list of message processing application processes of which the current node is in operation, and counting the number of the message processing application processes according to message types;
and step S609, updating the number of available processes and the resource idle rate in the message distribution control table according to the number of the message processing application processes.

Wherein the message types include at least: debit request class, credit request class, statistical query request class, and notify class.
In an embodiment, the detailed procedure of updating the message distribution control table in step S609 is as follows:
step S6091, calculating the number of available processes according to the number of the message processing application processes: N-M-P; wherein M is the maximum process number; p is the number of message processing application processes; n is the number of available processes;
step S6092, calculating to obtain the resource idle rate according to the available process number: r is N/M; wherein, P is the resource idle rate.

and calculating to obtain the resource idle rate according to the number of available processes: r is N/M; wherein, P is the resource idle rate.
5. A JMS message process distribution control method under WAS cluster is characterized in that the method comprises the following steps:
acquiring a request message and putting the request message into a message queue;
calling a JMS message interception process in the WAS cluster to intercept the message queue, and acquiring the message type and the operating node name of the request message;
accessing a message distribution control table by taking the message type as a screening condition to obtain a WAS node list allowing the message type to run;
judging whether the current node is in a WAS node list allowing the message type to run;
if so, judging whether the resource idle rate of the current node is the maximum; if the resource idle rate is maximum, subtracting 1 from the number of available processes of the current node, and starting a message processing application process to process the request message;
if the request message is not in the message queue or the resource idle rate is not the maximum, the request message is placed back to the message queue;
acquiring a message processing application process list of a current node in operation, and counting the number of message processing application processes according to message types;
and updating the number of available processes and the resource idle rate in the message distribution control table according to the number of the message processing application processes.
6. The method for controlling distribution of JMS message processes under a WAS cluster according to claim 5, wherein the message distribution control table stores message types, the allowed operating WAS node names corresponding to each message type, the maximum number of processes, the number of available processes, and the resource idle rate.
7. The method of controlling the distribution of JMS message processes under a WAS cluster according to claim 6, wherein the message types at least include: debit request class, credit request class, statistical query request class, and notify class.
8. The method of claim 6, wherein updating the number of available processes and the resource idleness in the message distribution control table according to the number of message processing application processes comprises:
calculating to obtain the number of available processes according to the number of the message processing application processes: N-M-P; wherein M is the maximum process number; p is the number of message processing application processes; n is the number of available processes;
and calculating to obtain the resource idle rate according to the number of available processes: r is N/M; wherein, P is the resource idle rate.
9. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein the processor implements the method of any of claims 5 to 8 when executing the computer program.
10. A computer-readable storage medium, characterized in that the computer-readable storage medium stores a computer program which, when executed by a processor, implements the method of any of claims 5 to 8.
