is it possible (and relatively easy) to add a remote agent for another system.
We are running an IBM mainframe using VSE/ESA operating system
can we write an agent that can at least handle the basic start jobs and return status

You can use universal version of 24x7 Remote Agent written in Java. If your system supports JDK or JRE version 1.4 or later you got everything you need to run this agent. As with other agents you can use to run/monitor jobs, get exits codes, get standard and error outputs, transparently access remote files and so on. For more info and to download trial version please visit http://www.24x7automation.com/download/ra_server_eval/ra_eval.htm

Note that 24x7 Remote Agents for non-Windows platforms are now called 24x7 Remote Automation Servers.

thanks
but if the system does not support java at all, as ours does not, this
would be difficult. If we implement the calls in the system would that work?

I am not sure I know what you mean by "the calls in the system?"

I see two possible options right now:
1. If you can write a C program sending and receiving TCP packets over a TCP/IP connection then you can probably convert code of existing AIX agent.
2. (preferred) If you got DB2 you can probably write a stored procedure to dynamically execute programs specified as in procedure parameters and return status code and possible error messages.

If option 2 is available then you don't need to write any agents. Just create the mentioned stored procedure and call it from 24x7 using IBM's ODBC driver for DB2 installed on the computer running 24x7.
For more info see http://www-306.ibm.com/software/data/db2/vse-vm/support.html

Hope this helps.
