Intelligent Agent startup with LINUX

Can anyone tell me how to start the enterprise manager intelligent agent for an Oracle 8.1.6 database under LINUX?

The command to start the intelligent agent on Linux is ./lsnrctl dbsnmp_start. The should be executed from the $ORACLE_HOME/bin directory.

8.1.7 Intelligent Agent on Redhat Linux 6.2

Hello,
Can anyone help?
My OEM fails to discover a Redhat Linux node but I can manually configure it (so the node address must be OK). When I check that the agent is running (lsnrctl dbsnmp_agent) it says that the db subagent is already running. If there is something obvious, I've probably missed it because I'm relatively new to both Oracle and Linux/Unix. Any clues, please?

I found this reply on Oracle Metalink and it worked for me (looks like agent on Linux for some reason does not use default ports:
On IA nodes, edit the snmp_rw.ora file and add the following lines :
DBSNMP.ADDRESS = (ADDRESS=(PROTOCOL=tcp)(HOST=<ip-address>)(PORT=1748))
DBSNMP.SPAWNADDRESS = (ADDRESS=(PROTOCOL=tcp)(HOST=<ip-address>)(PORT=
1754))
where <ip-address> is the IP-Address of the node to be discovered.
Note: ports 1748/1754 must be open for the OMS to communicate with the Agent.
The OMS starts communication on ports 1748 and 1754 to get the discovery
information from the Intelligent Agent.
The ports 1748 and 1754 are dedicated for the Intelligent Agent, and should
not be used by any other program.
Ports used by the Intelligent Agent:
++++++++++++++++++++++++++
During the discovery phase, the Communication Daemon OMS
will contact the Intelligent Agent via the ports 1748 and 1754 and retrieve
the discovery information.
Port 1748 is used for the basic communication, while the port 1754 is
used for file transfer. The communication is always initiated from the
Communication Daemon or OMS towards the Intelligent Agent.
The ports are hardcoded in the Intelligent Agent and should not be altered
in any way. The ports are referenced in the snmp_rw.ora file as:
dbsnmp.address=(address=(protocol=tcp)(host=somehostname)(port=1748))
dbsnmp.spawnaddress=(address=(protocol=tcp)(host=somehostname)(port=1754))
The meaning of the dbsnmp.address and dbsnmp.spawnaddress are solely to
determine the resolution path for the Enterprise Manager framework to get
in touch with the Intelligent Agent, and should not be used to specify
other ports.

Oracle Intelligent Agent Startup Error

Whenever I try to startup the Oracle Intelligent Agent on my DB server I get
the error:
could not open emtab at /var/opt/oracle/emtab.
I am using Oracle9iR2 and have installed the complete package. I did a
search of the HD and this file does not exists anywhere..which explains why
it was not found! does anyone know what I must do to resolve this problem?
can I just ignore this error???
Note: I only want to run the agent, the EM database is not installed on this machine but a seperate machine in another location.
Thanks in advance,
Steve,

No, just the 9i R2 database + EM, we don't use AS. Maybe I can just ignore this error?? Sometimes I notice oracle gives errors which are in fact just warnings or information. not very helpful as you never know. Not sure if I can ignore this or not.
Thanks,

agent installed.
I would like to monitor the database via OEM and
try to plan jobs etc.
I have problems to discover for services inside OEM (NT-Side)
I got the error Failed to find node address"
Who can shortly explain what must be configured.
Or has somebody configuration Files which will work ?

You mast start the intelligent Agent on the LINUX Box
lsnrctl dbsnmp_start
During the FIRST Startup the Agent generates its config files
(snmp_ro.ora,snmp_rw.ora) itselve....
You should complete your network configuration (LISTENER.ORA,
TNSNAMES.ORA and ORATAB (all in lower case within unix)) befor
starting the Agent the first time...

OEM 9i Supporting 10g Intelligent Agents

Hello.
We currently use OEM 9.2.0.1 for monitoring and tracking of our 9i database instances. I want to add in our application server when we go live with iAS 9.0.4.1. We're currently running 1.0.2.2, which of course is well behind the times. Will the 10g iAS Intelligent Agent communicate with a 9i EM? If so, are there any limitations, or special considerations I need to take into account? Thanks.

Nope. Totally different architectures.

Dicovering Intelligent Agent on Linux fails with VD-4565

I try to discover an Intelligent Agent 8.1.5 running on a Linux server with an Oracle 8.1.5 DB from an Oracle Enterprise Management Server 2.1. We just upgraded from OEM 2.0.4 to 2.1 and I had no problem with the Linux agent under 2.0.4.
After starting the Agent on the Linux server the SERVICES.ORA and SNMP_RO.ORA files contain the information about the services running on the server. When I start the Discovery Wizard it fails with the error 'Discovery Failed:VD-4565:The agent of the node is already being deleted'.
Then I stoped the agent and all service on the Linux server and did the following. I removed the SID_LIST entry from the LISTENER.ORA file and used the LOCAL_LISTENER init.ora parameter for the database. I know that the agent needs the SID_LIST to discover the database services, but I just wanted to give it a try. After restarting the database, listener and agent the SERVICE.ORA and SNMP_RO.ORA files did not contain any service information as expected. I tried to discover the agent again from the OEM 2.1 console and everything seemed to work fine. No errors this time. The Linux node was added to Nodes folder in the Navigator tree, but for sure no database or listener.
Therefore I put the SID_LIST back into the listener.ora file and restarted the listener and agent. The service information were included in SERVICES.ORA and SNMP_RO.ORA file again. So I tried a Refresh Node from the OEM console and the error VD-4565 showed up again.
Does anyone have any idea what's going on an how I can manage a Linux database from an OEM 2.1 console?
Any help is appreciated.
Thanks

Hello Peter,
I, alas do not have the answer for you. But... your symptom is EXACTLY LIKE MINE!!I was running OEM 2.0.4 and Oracle on a linux box (unfortunately, today I did something wrong and blew the database away!!!, I do not want to tell you how many hours I spend getting the database up, connected and communitcating with Windows NT box running OEM!) I made the switch from 2.0.4 to 2.1, and everything quit. More or less. I fixed my tnsnames.ora file on the NT side. That allowed me to connect. I got the Agent (sortof) running on the linux box and then I could discover the linux host computer name and domain, but it would not find ANY database. Although I could connect from the linux box, the nt box using oem (direct to db), sqlplus, and Access odbc!!! All listeners were there, etc. I did check the snmp*.ora files, and they would not discover anything (linux side) even though the LISTENER was listening, and tnsnames were naming and instances were instancing. My guess is yet another bug.
Sorry for long reply. Now I will RELOAD THE ENTIRE DATABASE AND APP AGAIN!! I so far have been totally unable to run on the liux side, net assist and net easy config, but I could sucessfully bypass those apps by correctly using and configuring initSID.ora, etc and the other *.ora files.
Eric

Any assistance would be greatly appreciated.

I don't think the Intelligent Agent is included with the developers release -
check the directory where it's supposed to be, I think you'll find it's not there.
You only need IA to start/stop the database from oem and schedule jobs.
I use OEM to control my instance and run performance packs etc, IA isn't needed for this.

Linux Intelligent Agent - OEM cannot discover node

Hi,
I have a Linux AS 2.1 Server with a Oracle 9.2.0.1 Database running. I have 2 Oracle Management Servers ... one is running on this running on the Linux AS 2.1 Server and another on Solaris 9i.
When start the OEM on the Linux Server and try to discover the Databases on the Linux Server themselves then everything goes fine. When I am trying to discover the databases on the Linux Server from the OEM running in Solaris it does not work.
The Solaris box has connection to the Linux Server and the repository for the Solaris OEM runs on the Linux Machine.
When I go back to the OEM on the Linux Machine then I can discover the Solaris box.
To come to a boddom line here: Whatever I do I am not able to discover the databases on the Linux AS Server besides from the OEM directly running on this box.
Is that a bug in the Linux Intelligent Agent ? If yes is there a Patch to fix that ? Or is there a work around.
Please let me know if you have any idea.
Thanks Marcus

Ok I figured it out .... the problem is/was the entry of the Loopback Interface entry in the etc hosts:
127.0.0.1 dbserver localhost.localdomain localhost
The Intelligent Agent listens to the Loopback Interface now. All incoming requests from and OMS will of course get a timeout because the IP address of the server is 10.1.0.10 .
You have 2 options now:
1. Change the entry in the /etc/hosts below to localhost and add an entry to the /etc/hosts file:
127.0.0.1 localhost localhost.localdomain localhost
10.10.0.1 dbserver
Restart the Intelligent Agent and any OMS in your network should be able to discover the note.
2. In the snmp_rw.ora file you can bind the Intelligent Agent with the following entries to an specific hostname and/or port:
DBSNMP.HOSTNAME = <hostname or ip address>
DBSNMP.CS_BASE_PORT = <port number>
If you start up Agent now you will see in the nmiconf.log file error messages like that:
Warning: No Listener found for SID db01. db01 will be skipped
Warning : No Listener found for SID db02. db02 will be skipped
Warning : No Listener found for SID db03. db03 will be skipped
Warning : No Listener found for SID omsrep. omsrep will be skipped
This is because the Agent looks up in the tnsnames.ora file or whatever you name resolution is and finds the connect descriptors still withe the old name. So all entries in the tnsnames.ora file have to be changed.

INTELLIGENT AGENT PROBLEM RECOVERY ON NT

제품 : ORACLE SERVER
작성날짜 : 1997-12-16
The Oracle Intelligent Agent 7.3.3 on NT is self-configuring and
requires TCP/IP fully configured on the NT system.
The Agent's startup algorithm:
When the agent is started, the startup process reads the LISTENER.ORA,
TNSNAMES.ORA and NT REGISTRY. It compares the values stored in each location.
If any discrepencies exist, the agent service will either not start
or service discovery will not occur.
Starting the Intelligent Agent:
1. Verify the Sqlnet configuration files are correct:
- All sid entries in the LISTENER.ORA must have valid TCP/IP service
descriptors defined in the TNSNAMES.ORA file.
- The TNSNAMES.ORA should not contain service descriptors for local
sides not defined in the LISTENER.ORA file.
- TCP/IP must be fully configured on the system.
2. NT 4.0: Click on START->SETTINGS->CONTROL PANEL->SERVICES.
Highlight the service ORACLEAGENT. Click on the START button.
NT 3.51: Find the MAIN program group.
Click on CONTROL PANEL->SERVICES.
Highlight the service ORACLEAGENT. Click on the START button.
***NOTE: If the 7.3.3 agent will not start, verify the OEM version
is not 1.4.
If the version is 1.4, install the 8.0.3 Intelligent Agent.
Agent troubleshooting tips:
1. Verify TCP/IP is configured correctly.
- At a dos prompt, type HOSTNAME.
This is the actual configured TCP/IP HOSTNAME of the system.
- Verify the hostname resolved by the agent. The DBSNMP.ADDRESS
parameter in the ORANT/network/snmp_rw.ora contains this
information.
If the file does not contain the actual hostname, TCP/IP is not
properly configured on the system or the network.
2. Correcting TCP/IP configuration problems:
- Edit the WINNT\system32\drivers\etc\hosts and lmhosts files.
(*NOTE: If these files have never been used, only sample files will
exist in the directory. Either rename or copy the .sam files
to just the file name with no extention.)
- Follow the example below (replace the information in brackets
with the actual host information for that system.):
HOSTS file:
<122.111.111.111> <hostname>
LMHOSTS file:
<122.111.111.111. <netbios name or hostname> #PRE
- Delete the ORANT\network\agent\*.q and SERVICES.ORA files.
(*NOTE: The *.q files hold information about jobs and events.
Do not delete these files without first removing all jobs
and events registered against this agent.)
- Delete the $ORACLE_HOME\network\admin\SNMP_RO.ORA and
SNMP_RW.ORA files.
- Restart the agent at a DOS prompt:
NET START ORACLEAGENT
3. Check the NT EVENT VIEWER->APPLICATIONS->LOG for any errors
starting the DBSNMP process.
4. Check the ORANT/NETWORK/LOG/NMICONF.LOG file for other possible
errors.
5. If using NTFS, check permissions to the \orant\network directory
structure.

OMS and Intelligent Agent not seeing databases

I am running Oracle9i on a Solaris box and trying to set up OMS on a PC. I managed to get the intelligent agent started on the Solaris box but now when I do a node discovery, all that I can see is the HTTP servers and they say that they are stopped. How do I see the databases so I can schedule jobs on them?

If databases are not discovered, you could have a problem with any of the following files.
listener.ora
oratab ( UNIX/Linux)
Microsoft Registry (Windows)
1. Check the $ORACLE_HOME\network\agent\log\nmiconf.log for warnings or errors.
2. Verify the database sid exists in the listener.ora file. When the Agent parses the listener.ora, it looks for the "sid_list=...." section. If this section is missing, the Agent will not discover the database.
3. Verify the database sid exists in the oratab or Microsoft Registry. (In some cases, the sid is case sensitive.)
4. Stop and Restart the Agent. NOTE: This step is necessary because the Agent will only parse the files during startup.
5. Check the services.ora file and verify the Database services now exists in the file.
6. Refresh the Node through the EM Console.

OEM Repository and Intelligent Agent

How many OEM repository and Intelligent Agent do I need to have to schedule a unique job on three of the 4 databases I have?

Has Anyone gotten the Intelligent Agent to work???

I have Oracle installed and all is well except for a few minor
problems that I think the Intelligent Agent will solve. Has
anyone gotten this to work on RedHat 6.0 with Oracle
Enterprise Edition 8.0.5.1??? I was able to get it to work
under Oracle8 SE, but I need EE for the ConText Cartridge.
I have gotten to the point where I can get the dbsnmp process
running, but OEM cannot talk to it.
Please help

I'm having the same problem. Does anyone out there have a
solution?
I am running RedHat Linux 6.0 straight out of the box. The only
change I made was to set the kernel parameters according to the
release notes and recompile the kernel.
P.S. Oracle deserves our thanks for providing free developer
licenses to so many of its products, but this is the buggiest
install I've ever seen in my 12 years of working with their
products. Didn't anyone from Oracle test the install? This
problem and the zero length libnjni8.so file are the real
doozies.
I've followed the release notes and installation guide to the
letter and have found several documentation / distribution bugs
that should have leapt out at the first person who tried it.
