Setting up Change Assistant

Running batch file as service

Mon, 28 Sep 2009 13:03:38 +0100

Yes - I ended up using a ShareWare utility to wrap the agent into a service so it could be auto-started at windows launch without logging in, and also started/stopped at will. Since then, found a useful resource on this: http://www.windowsnetworking.com/nt/atips/atips112.shtml which gives a few different methods for doing this using standard NT tools. - Simon Huggins

There's a good thread on Yahoo groups http://tech.groups.yahoo.com/group/peoplesoft-fans/message/45812 that makes some good points about Change Assistant. - Brent Martin

In the Database Config Page, while setting up the Environment the Old PS_HOME is Disabled. Is there any setup to be done for this to be enabled.

Please Advise.

You asked, "I don’t have a good command to run the agent in the background on NT. If you have one, please share!"

I'm not a PeopleSoft guru, but I'm about to try running the StartAgent.bat file as a scheduled task. After reading your article, yesterday I decided to try this. It appears to work at least on the level of the agent registering with the PSEMHub.

There are some settings I chose to ease administration.
1) Create two scheduled tasks one called PSEMAgentStart and PSEMAgentStop. (Each pointing to the appropriate StartAgent.bat and StopAgent.bat files and working directories).
2) Set each task to run as "System". Hint: don't try supplying a password, system is the computer account and it will handle password changes, etc. for you.
3) (optional) Remove the checkbox next End this task if it runs for more than 72 hours. This allows you to view the job as "running" on the server side, but is really more of an aesthetic than a real indicator of status. If you don't modify this property the task, after 72 hours the task will not show running in the Task Scheduler, but it will continue running the agent. Use "hubURL" from the article to view the status of the PSEMAgent.)
4) Right click the PSEMAgentStart task and choose "Run".

This was tried on Windows Server 2003 SP1 server, but I couldn't verify that CA actually works properly, as I don't know how to test CA client. Maybe someone will be kind enough to verify this works or doesn't work. As I indicated the agent runs and registers with the PSEMHub but beyond that I can't say for sure.

Maybe this will help someone. - Chris Hulsey

That's an interesting question. Unfortunately I'm not aware of anything out of Oracle that documents the communication process. It looks as though communication between the Agents and EMHub occurs via XML over HTTP, so I might speculate that Change Assistant uses XML too. I'm not sure if Change Assistant contacts agents directly or if the EMHub brokers the conversation.

There's certainly no API that I'm aware of. It seems very closed and proprietary. - Brent Martin

Excellent article! I've been looking into using the PSEM framework for other purposes like actually managing the environment from one single console. Are you aware of any info regarding the internals and how the communication between the CA and the EMHub actually happens? Protocols, any API etc that they have made public?

Thanks for a very informative article! - Amr Malik
