DataDirect IDMS Extensions OCA-MQ
MQSeries messaging software enables business applications to exchange information across over
thirty different operating system platforms in a way that is straightforward and easy for programmers to implement. MQSeries provides assured, once-only delivery of messages.
Product Description
DataDirect's IDMS Extension OCA-MQSeries enables CA-IDMS programs to use IBM's MQSeries middleware product. At the heart of MQSeries is the Message Queue Interface (MQI), an easy to use high level programming interface that allows applications to communicate transparently across the various platforms that make up your enterprise-wide computing environment.
Key Features
- Full support for all MQI calls
- Trigger Monitor
- High performance, multi-threaded architecture
- Supports for Cobol, ADS/Online, PL/I and Assembler languages
Full API Support
OCA-MQSeries supports all Message Queue Interface (MQI) calls. The interface program can be invoked using either a static CALL or a dynamic LINK (or TRANSFER). All functionality is supported including Two-Phase Commit, with the use of the optional OCA-Commit component.
Managing communications made easy
A solution to the problem of managing an increasingly complex web of communications is to get applications to work in a non-serial, asynchronous manner. Rather than talking directly to each other, they communicate transparently through a common third party : MQSeries. MQSeries sits between the application and the network to iron out system differences.
Transparent communication across various platforms
At the heart of MQSeries is the Message Queue Interface (MQI), an easy to use high level programming interface that allows applications to communicate transparently and easily across the various platforms that make up your enterprise-wide computing environment.
Perfect integration with Internet and Intranet
MQSeries can be used by your CGI scripts and Java applets, servlets and applications to transfer information or send requests to your IDMS system. All the data sent by programs using MQSeries is garanteed to eventually make it to IDMS. Applications can then be initiated automatically using a Trigger Monitor to process the data. Data can even be converted between ASCII and EBCDIC automatically. That is why it integrates perfectly with your Internet/Intranet strategy.
The Trigger Monitor: An attentive listener
A Trigger Monitor is an application program that listens to a Trigger Queue (also called Initiation Queue). MQSeries can be instructed to send a special message to a Trigger Queue when data is available in an application queue. The Trigger Monitor reads that message, which contains the name of the program that should be initiated, and starts the requested task. Multiple instances of the Trigger Monitor can be used to listen to any number of Trigger Queues.
Performance
OCA-MQSeries has been designed to take advantage of multiprocessing. Almost all of the additional cycles required by socket calls are executed by OS subtasks. This means that the additional workload can be shared between all the processors in the partition.
All programming languages
Because the OCA-MQSeries interface program can be invoked either statically or dynamically, all programming languages supported by IDMS can be used including ADS/Online.
