Good morning all,
Our test database is a single node db in Sun Microsystems Inc. (SunOS 5.10). The database version is 10.2.0.4. We have an oem agent (10.2.0.4) installed in this db server communicate with a 10g grid control. Everything is working fine. Now we are trying to migrate this db server under 11g grid control. So what we did is installing new version of agent (10.2.0.5) into a different directory and configure this agent to talk to 11g grid control. So basically we have two agents installed in this db server. One is 10.2.0.4 agent which is talking to 10g grid control and another agent 10.2.0.5 which is talking with 11g grid control. Although both agents are running but we experience some issues: First, we noticed that all listeners in the server are in “Status Pending” in 11g grid control but actually all listeners are up. Second, a notification rule has been setup in 11g grid control to monitor one db instance and I purposely set the threshold very low so I can receive the alert email. But the all the alert emails actually comes from 10g grid instead of 11g where I set threshold very low. I am not sure how agent works internally so I am not sure if multiple agents will ever be work in one db server. Does anybody have any thoughts on this? Any insights to share?
Greatly appreciate your help!
You not there are most of the things about a target which are stored locally on the target rather than on the GC itself. For example, if you set t matrix value for a database target, it is stored on the database itself whether you use 10g or 11g GC . Here in your case, i think your both GC are fighting together to monitor a single target which is configured on both and i think it will not be supported (you can confirm from MOS). So my advise will be to configure your targets with only one GC (either 10g or 11g)
