Hi ,

We have an old Grid setup on but we now we want to have a complete new setup on on a completely different server. My doubt is what should we do with the existing agents on the target databases which are getting monitored on the old Grid environment. Should we delete the existing agents , if Yes can somebody help me on that.

If yes there is any other approach for that , kindly help me on this.

And also , is the kernel parameter values mandatory to specify in the /etc/sysctl.conf

rmem_default = 262144
rmem_max = 262144
wmem_default = 262144
wmem_max = 262144

The reason being this is our Sysadmin has told that they are not getting set while installing .

Kindly suggest on this .

1. Install new OMS with version on new server
2. Upgrade target agent (if required as I suppose is also supported with OMS)
3. reconfigure agent with new OMS

Agent reconfiguration steps:
1. stop agent
2. go to $agent_home/sysman/config
3. take backup of file emd.properties
4. edit emd.properties and change new OMS name (new server name) in place of old OMS. Mainly 2 parameters need to change in file are REPOSITORY_URL and emdWalletSrcUrl.
5. remove old logs...

rm -r $agent_home/sysman/emd/state/*
rm -r $agent_home/sysman/emd/collection/*
rm -r $agent_home/sysman/emd/upload/*
rm $agent_home/sysman/emd/lastupld.xml
rm $agent_home/sysman/emd/agntstmp.txt
rm $agent_home/sysman/emd/blackouts.xml
rm $agent_home/sysman/emd/protocol.ini

6. clear agent state
7. secure agent again if required
8. start agent


Yes, these kernel parameter values are mandatory to specify in the /etc/sysctl.conf
