I was a newbie with Virtualbox and Enteprise Manager 12C with OEL6 (64-bit) was quite a new combination, so what can go wrong…?
You could do the following:
The metric 'swap utilisation (%)' on the node where Grid Control resides, shows permanently a very hig value. Red Hat Linux, 64-bits, 32GB RAM, 4GB swap. Adding 4GB to the swap-file solved the problem.
After installing and configuring application server, the agent on that server started to sent messages like 'The number of active connections is ..' . But.. there are no connections yet on the system (as far as I know)! Grid Control (OMS + agent) = 10.2.05, application server 10.1.2.0.2
Grid Control is calling >> “Difference between OMS system time and Agent system time is 121 mins and has exceeded the critical threshold 120 mins”
The system time runs too fast on a (Suse) Linux-based (kernel 2.6) virtual machine, while the ntp has been configured. There are a lot of documents […]
Short one this time, all in favour of getting my green ‘pie’ in Grid Control management server.
Grid Control: 10.2.0.5. Discoverer: 10.1.2.x
In Grid Control, after upgrade to 10.2.0.5, a Discoverer target shows down in the list, while it’s functioning quite well.
It seemed an old bug (Grid Ctrl 10.1.04) is still not […]
After installing Oracle Application Server 10.2.0.2, with corresponding OID, Grid Control 10.2.0.5 gave me the obove mentioned error, and the the item OID gave a 'metric collection error'. To fix the metric collection error downloaded and applied Patch 5686191 on top of OID product.This is a sql-script to run against the OID-repository.
Platform: application server 10.1.2.0.2 on Suse Linux 9. Grid Control agent 10.2.04.
All components within the application server are up, but the home page of Grid Control showing it down.
Underlying cause: bug in discovering ports by the agent. Agent discovering process gets Forms url Port from < HOME_IAS>/10.1.2/forms/server/target2add.xml. But this port […]
Agent (10.2.0.4) crashes – on a site (64-bit) with many databases (10.2.0.3) a lot, intermittently – , too many open files, emagent.trc gives ‘health check’ error
Agent gave messages – in the past – like this:
Number files opened by Agent is 1140.
These files appeared to be the $ORACLE_HOME/dbs/hc<instance>_.dat which is […]
On my Grid Control management-server (Suse Linux, OMS version 10.2.0.4) a very large number of <defunct> processes arose what eventually caused the OMS not to respond anymore.
Looked like this:
oracle 16932 15961 0 Mar03 ? 00:00:00 <defunct>
oracle 16987 15961 0 Mar03 ? 00:00:00 <defunct>
oracle […]
Redelijk gedoe met versies. Basis: Suse Linux 9, 32-bits. Agents op Suse Linux: versie 9 en 10, 64-bits.
