People, I made some progress. I found a blog with a hint which probably fixed my problem: http://www.dbazine.com/blogs/blog-cf/chrisfoot/blogentry.2005-09-17.7657940139 There is one other parameter in emd.properties that may cause a few problems. If your agent NEVER successfully uploads data after installation, check the TIMEZONE parameter in the emd.properties file. It is usually the last parameter in emd.properties. When our agent's time zones didn't match the time zone in the management server's configuration file, we weren't able to establish a successful connection between the agents and the management service. So if you have agentTZRegion=America/New_York in the agent's emd.properties file, you'll prevent a lot of headaches if you use the same time zone in the management server's emd.properties configuration file. We don't have any servers in different time zones, but there is a wealth of information contained in the 10G Grid Control documentation to help those that do. What I do know is that when the time zones didn't match, we couldn't make a connection. On my host, the values for agentTZRegion did not match. For the agent I have this: agentTZRegion=US/Pacific For OMS I had this: agentTZRegion=GMT For OMS I now have this: agentTZRegion=US/Pacific After I made the changed I bounced oms with this: emctl stop oms emctl start oms Then I bounced the agent. Then I did: bash-3.1$ bash-3.1$ bash-3.1$ emctl upload agent Oracle Enterprise Manager 10g Release 10.2.0.1.0. Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved. --------------------------------------------------------------- EMD upload completed successfully bash-3.1$ bash-3.1$ That was encouraging. I checked status: bash-3.1$ bash-3.1$ bash-3.1$ emctl status agent Oracle Enterprise Manager 10g Release 10.2.0.1.0. Copyright (c) 1996, 2005 Oracle Corporation.

And I nosed around in alerts and found a bunch of new alerts which had been bottled up in Agent alert queue. And I check my e-mail, and I had a bunch of new e-mail alerts. So the smell of some progress is sweet. But... I have no idea how this POS software ended up in this hole and I don't have much of a clearer picture of how it works. Anyway EM-GC is functioning in my lab and maybe it will stay stable for another 10 minutes. ...Peter http://GoodJobFastCar.com
