Hi
We are looking into options of having an MQinterface on AS400 From the MQSeries manuals we can have the interface written in bothe RPG as well as Java.
Can any one pls let me know which programming language will be the best among two for having the interface (RPG vs Java) on AS400.
Performance will be the criteria
Thanks and Regards

What kind of skillset/background do people have who will code/maintain this?

Hi Kiran
Thanks for the reply, We have both kind of skill sets with us but expertise on Java on AS400 is comparitively on lower side when compared to RPG on AS400.
but our strong RPG resources have less knowledge on MQ. We had built Java MQ interface for other environments (Unix, WinNt, mainframe uss environments) not on AS400.
The reason I am looking into this is , I feel having an RPG interface would be much faster, and from the display screen I could directly invoke an RPG interface and put the messages into queue , the message can be constructed on the fly aswell as 2 fold process (to file/db and then route it to queue). In Java the interface can put the message in only in the 2 fold process
Looking at the above options pls provide your suggestions
Thanks in advance
Thanks and Regards

I've worked atleast on one project on 400 with MQ. To start with we tried to use Java(thats what my skillset is). I was told that the only way to invoke a java program on 400 is by first invoking a unix subshell, and then the java program. I don't know if that's the only way to do it. This obviously was not what we wanted. I was unfamiliar with RPG. We instead used C programs, which were way too fast compared to the java programs(Believe it or not, 100 times faster, because of that unix subshell overhead). I'd suggest you to use RPG if possible(unless there is a better way to invoke java programs).
Especially if you use triggered apps, and trigger type every for a considerable volume of messages, java programs become a p-in-a.
On the other hand, I don't know how extensive RPG APIs are, development efforts will be relatively easier in Java because of the number of APIs available. But if performance is the key, java will not be an option on My list. |
