Queries

[akash]

Hi,

I heard about this group. I just moved to Tandem tachnology. liked it
very interesting. I have few queries which I am not able to find it
NTL site.
1. Is it possible to call a Java Program (running in OSS Unix-tandem)
through COBOL program (running in Guardian-tandem).

2. How to include and use IPC in COBOL (running in Guardian-tandem) to
send/use by Java (running in OSS Unix-tandem).

3.Can we invoke any Tacl program/OSS Unix shell script thru stand
alone COBOL (running in Guardian-tandem).

If anyone of you can help me, it would be great.

Thanks
Akash.

There are at least two ways to do this, maybe more.

One way is to use TCP/IP. That is pretty simple on the Java side, using standard Java libraries. On the COBOL side, it would be a little more difficult -- you would have to use ENTER TAL "xxxx" to call the various system procedures needed to do TCP/IP communications in the Guardian environment.

Another way is to use Guardian interprocess I/O. There is a Tandem-specific Java library known as jToolkit, which includes something named "Pathway API for Java", which provides the ability to read and reply to messages on $RECEIVE. It is possible to give a Guaridan process name to an OSS process, so when you start the OSS Java program, you can give it a process name that the COBOL program can communicate with as it would to any other server process.

See the second method I mentioned in the answer to the previous question.

Yes, you can start a process using either the low-level Guardian procedures (PROCESS_LAUNCH_ or PROCESS_SPAWN_) or the COBOL-specific library called the Saved Message Utility. I think the Saved Message Utility can create only Guardian processes, so to use it to run an OSS shell script, I imagine you would run the OSH program with the appropriate parameters to get it to run the OSS script.

If the above clues still aren't enough for you to find the information you need in the manuals, write again and ask a more specific question about what you are trying to do, and one of us probably can help further.
