Enterprise Manager - Question

[muckley]

To whoever can help........

We have since installing Enterprise Manager created three new instances. Now whatever we do we cannot get them to appear in EM. We have tried refreshing the node option and this seems to make no difference whatsoever. If we use DBA studio as a standalone we can add them to the tree no problem, but using the OEM server they dissapear again.

Any help would be gratefully accepted.

Regards,

Simon.

Hi

You can try the steps below

This usually happens if the following files are corrupted

snmp_ro.ora
snmp_rw.ora

The above files are located in

$ORACLE_HOME/network/admin

and also if any of the files located in the following folder are corrupted

$ORACLE_HOME/network/agent

The Problem occurs in Windows NT/2000 while executing
Discovery Node as it depends on Oracle Intelligent Agent and
if any of the above files are corrupted for whatsever reason
follow the steps below

1) Stop the Oracle Intelligent Service using services Icon
2) Delete the following files

snmp_ro.ora
snmp_rw.ora

which are located in the following folder

$ORACLE_HOME/network/admin

3) Delete all files from the following directory

$ORACLE_HOME/network/agent

Do not delete any other folder in the above directory

4) Restart Oracle Intellingent Service from the services Icon
When you restart the service it will recreate all the above files in the corresponding folder

Invoke Oracle Enterprise manager and select Discover Nodes

Let me Know how it goes

Hello

you gottta to ensure that intelligent agent is running on the node where you r running the databases.

use this to know wheather intelligent agenbt is running on the nodes

lsnrctl

lsnrctl>dbsnmp_start

Guys,

Thanks for your help.....there are definately no entries in snmp_ro.ora ,snmp_rw.ora for the new instances we created. I have a feeling that intelligent agent is not running. Using dbsnmp_start does not seem to make any difference.....and I cannot find it in my services list.......is there anything else i can do to confirm its status or start it up.

Many Thanks ,

Simon.
