Hi guys,

I have an installation of RAC 10.2.0.2 x86-64 in a RH-EL 4.4. This installation is in production. When I install the Oracle Agent Grid Control 10.2.0.2 in all nodes, the job is finalized successfully and agent is started successfully.
After a few moments, the message above is displayed in emagent.trc and agent is crashed.

[oracle@node01 log]$ tail -f emagent.trc

Hi all

I have exactly the same probelm on a 4-Node RAC Cluster. After restarting the nodes, everything is shown green in Grid Control and a few hours later, there is the message "Agent unreachable" for all RAC nodes.

I'm running Enterprise Linux 4 U5, Oracle 10.2.0.1 and agent 10.2.0.3.


Thanks for any help !


cheers

Did you create another ORACLE user and GROUP for agent installation?Try it with the existing user.

OK, I've got the solution:

Important is the message about too many open files. This is caused by operating system running out of open file handles limit (default for linux is 1024).

You need to increase the file descriptor soft limit per shell to 4096 from default 1024.

# vim /etc/security/limits.conf

#oracle soft nofile 1024
oracle soft nofile 4096
oracle hard nofile 65536


After that, the agent works fine, without problems.
