Oem Agent not starting anymore..

This morning I noticed a database down in our OEM application. I also received an email from the inicident, so I decided to look into this problem. I found a sollution very quick. It seemed the dbsnmp password of the target database was not valid anymore. So I changed the password in OEM, configured the target again en the problem was solved...

But then the agent stopt running and was producing al lot of errors like ..

EMAgent exited with signal 6

EMAgent is Thrashing. Exiting watchdog

oem agent Segmentation Fault

Could this have something to do with the password reset I did before ? I looked into the log/trace files but could not find anything special, except these errors. I decided to change the dbsnmp password again and not to change it in OEM, so the agent could not connect to the target. This time the agent started.

Chekcing the target again, I found the follwoing when executing sqlplus as system...

ORA-28002: the password will expire wuthin 7 days.

The target is a 11g database, could this be the problem ? I decided to edit the 'DEFAULT' profile.

alter profile default limit password_life_time unlimited;

Changed the system password back to is't previous value (so nothing changed...) and everything was fine.
The target is up and running in OEM..

Oracle E-Business Suite R12 with OEM10G

After configuring the Oracle EBS 11.5.10 environment in OEM10G, it was time to also configure the new Oracle EBS R12 environment in OEM10G. Before I could configure R12 in OEM10G, I first had to upgrade the Oracle Applications plugin for EM10GR3. I downloaded the patches p5489352_R12_LINUX.zip and installed this patch on the OMS_HOME and in the local AGENT_HOME's (11i and R12 agent). For R12 also patch p5843357_R12[1].OAM.A_R12_GENERIC.zip was installed...After applying the patch, my first 11.5.10 configuration didn't work anymore, so I had to rediscover both R12 and 11i again. After rediscovering both environments, I was able to drop the old 11i target. So, now I have both environments in OEM10G. The services to be monitored look a little bit different for R12, because of the 10g iAS...Also OAM is integrated into OEM10G, so you can drill down into the EBS R12. How to configure R12 and 11i with the new Oracle Application plugin is documented in a Getting Started.pdf (can be downloaded from Metalink). So, now I am ready to monitor....
