REXX server/Java client

Postby moral » Thu Aug 16, 2012 2:03 pm

Hi everyone
First I'm sorry for my english.
I'm new in mainframe environment but day by day I learn new things. Now I'm learn about REXX and find Redbook: "Implementing REXX Support in SDSF".
In this book is chapter about server in REXX and desktop client in JAVA. In this book the REXX server use a UNIX System Services too create a multitasking environment but in my comapny we haven't UNIX. Is ane other way to write that server? Is possible write JAVA client which can browse data set, SDSF, send e-mail or I'm a dreamer.
I do not expect the ready solution I only ask about the pointers where to look for.

Do you have access to OMVS - the zOS equivalent of unix? It would most likely be a menu option somewhere or issue command OMVS on a command line.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

I checked what you ask. I write the OMVS in command line end i see USER:/SYSTEM/tmp:>

Hello and welcome to the forum,

REXX can interact with SDSF without using USS/OMVS or Java.

What do you want your REXX to do? If you explain your goal, someone may have a suggestion.
Hope this helps,

Hi
I try write a client/server system.
REXX server on mainframe/JAVA client on windows.
Client send request to the server and server corresponds to client, ex. client request a list of member or output SDSF.
P.S.
I have problem with connection between hercules emulator and windows.

Hello,

I suspect that you should be using a "real" mainframe and not something running under Hercules. . .

Which operating system are you running on Herecules?

Now I'm learn about REXX and find Redbook: "Implementing REXX Support in SDSF".
This is written for the mainframe, not the emulator . . . Well, as far as i know.
Hope this helps,
d.sch.

I use emulator only for test. I have real mainframe in work. On Hercules I running z/OS.

Hello,

I suspect you will have a better testing experience if you use the real mainframe for this testing.

There is a strong possibility that if you get something running on Hercules, it will not work the same on the real mainframe.

Just a thought. . .
Hope this helps,

What do you want your REXX to do?


Chapter 10 of that fine manual describes two programs and seems to provide the source as well. There are various examples that can be strung together to make the server program. I think the poster just wants to get that sample program running.

create a multitasking environment but in my comapny we haven't UNIX

It seems like there is some confusion in terminology... you do not need a separate UNIX system. Unix System Services is part of z/OS. And it seems like you can issue OMVS command, so you should be able to issue the rexx SYSCALLS function as shown in the Redbook.
