oem find node, but not database

Hi

I set a database and oem on my NT using Oracle 8.1.7.
OEM can find the node on which I run my Oracle
instance, but when I click on the node, no database
is shown.

Anyone can help me out?

Thanks,

did you try refeshing the node and see what it says:

If your agent is not running it can't show up your database and should show up error saying agent might not be running.

check typing at the prompt of node(box)

$lsnrctl dbsnmp_status

If your agent is running okay on the server, check the following file (on the server) --

oracle_home\network\agent\services.ora

This should have a list of all the services, your agent is listening to (your database service should be listed there)

agent is running, while my service.ora is empty.

How to config service.ora file?

Thanks,

Go to box and see any seervices are running by typing in

$lsnrctl status

If no services, agent will not show up any services. Agent will check tnsnames.ora/listener.ora for services and double checks with oratab. If none defined it says it can't find any ..

OK,

Now I have service.ora file under network\agent directory,
and I restart agent using both Service control and dbsnmp_start. But when I check agent status using
dbsnmp_status, it says:
The subagent is not started.

BTW, lsnrctl status returns
one service on my Oracle instance
And I can connect user/passwd@service_name.

How to start the agent???

Thanks,

I had a similar problem on one 8i database on NT...it will start the agent but will not show any services listed. I tried fooling it by manually updating the services.ora and other related files like snmp_ro.ora in network\admin directory but it didn't work.

I guess I ended up reinstalling the Agent. But I will be watching this thread to see if somebody has a real solution to this problem.

Did you try starting agent using dbsnmp_start. What happened when you try to start dbsnmp agent ? If not try

lsnrctl dbsnmp_start

< dbsnmp_status, it says:
The subagent is not started>>


I don't know what this error means but I get this error on all the servers when I run "dbsnmp_status" from "lsnrctl" but the agents work fine everywhere and monitor all the databases !

sreddy,

Yes I tried:

lsnrctl
status -- OK, I can see service for my Oracle instance
dbsnmp_status
The subagent is not started.
dbsnmp_start -- No error message at all
dbsnmp_status
The subagent is not started.

I also tries to use service control to start/stop
agent/listener/service.

Not luck.

Iam afraid that you might need to reinstall agent. As a final check can you check


$TNS_ADMIN/log/dbsnmpc.log
/dbsnmpw.log
/nmiconf.log


And see anything you can find....


Whats your NETWORK ADMIN(TNS_ADMIN) set to ? which version if you have multiple versions.

One more thing I want you to verify is if you have installed two different versions of Oracle (or Oracle Agents) on that server.

For example on one of my NT servers I have two versions installed (8.0 and 8.1.5)
They both have their own agents and their own sets of listener etc files.

From OEM when I try to monitor 8.0 databases I need to make sure that the 8.0 agent is running. It does not work with the 8.1.5 agent.
