OEM GRID CONTROL CONNECTION ERROR

Hi everyone,
After installing oracle enterprise manager grid control and the installation was succesful, i got the following error while trying to connect i.e
While trying to retrieve the URL: http://crmdbts1.mtbplc.com:4889/em
The following error was encountered:
Unable to determine IP address from host name for crmdbts1.mtbplc.com
The dnsserver returned:
Name Error: The domain name does not exist.
This means that:
The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.
Your cache administrator is unknown.
Kindly help out to resolve this issue, what could have gone wrong?
expecting your replies soon.
++Let the knowledge sharing continue in building a better and stonger oracle community forum++

Problem is probably DNS. Ask your network admin to put an ip address to your Fully Qualified domain name crmdbts1.mtbplc.com.
In the meantime, if you are trying to connect from your workstation, you can enter an entry in your hosts file e.g.
192.165.80.9 crmdbts1.mtbplc.com

Hi,
We have installed OEM Grid Control 11g on a Linux Suse 10 machine (which will act as a middleware/gateway machine to the database hosted on the remote machine.)

Error while installing OEM Grid Control

I am getting error while installing OEM Grid control (with existing database) at OMS Configuration. So, I cancelled the installation and deleted all databases and started the instal again. I am still getting an error at OMS configuration.
I am trying to read through the threads here to see if anyone has solved it. I see a lot of threads on this topic but not sure how you guys resolved it.
Can anyone help here.
In the oracle installer, I see the message : The c:\oraclehomes\agent10g\cfgtoollogs\configToolfailedCommands" script contains all commans that failed, were skipped or cancelled ....
--in this file, all I see is:
rem Copyright (C)1999, 2006 Oracle
oracle.sysman.emcp.agent.AgentPlugIn
How should I proceed
Thanks

OEM GRID CONTROL REMOTE INSTALLATION

Hello Good People,
I am trying to install OEM GRID CONTROL. I have a two RAC node (AIX 5L). I don't have acces to the server so my only option is remote installation.
I was able to ftp the file into a directory on the server but it will not unzip, (error: couldn't find 10g.zp or 10g.ZIP). I uploaded the file as binary.
Okay, I will like to install from my laptop, (xp) using the DVD that I have. I went through the documentation steps below:
1. Make sure that the remote access software is installed and running on the remote and local computers.
2. On the local computer, share the DVD drive.
3. On the remote computer, map a drive letter to the shared DVD drive. You would use the remote access software to do this on the remote computer.
Through the remote access software, run Oracle Universal Installer on the remote computer. You access Oracle Universal Installer from the shared DVD drive.
I am confuse with step 2 downward. How can I map a drive in UNIX or why should I? I am connected to the sever by Telnet.
Any direction or suggestion will be appreciated. Please note that all I want is to remotely install GRID CONTROL on my server from the DVD that I have.
Thanks for your help.......

Based on further researched I discovered that the problem is due to the fact that I don't have an X-Window client install on my local machine. I just install a free trial version (30days). OUI finally started and went through the various checks. Although, the check passed I couldn't continue. It is saying missing some files. I will post the erros messages from the log in a while.
Thanks

Linux OEM Grid Control 10.2.0.1.0 installation issue

Just a heads up to anyone installing Linux OEM Grid Control 10.2.0.1.0
If you are doing a full install, the "product specific prerequisite checks" page will show an error on the following packages even if you have them installed.
compat-libstdc++-296-2.96-132.7.2 (failed)
libstdc++devel-3.4.3-22.1 (failed)
openmotif-21-2.1.30-11 (failed)
Note that the installation works fine if you ignore the "missing" prerequisites. I believe the check itself is flawed. The openmotif check should be openmotif21-**** (extra hyphen incorrect in check - the old install was openmotif, now openmotif21), the libstdc++ needs a hypen added before the devel, and the compat-libstdc++ has yet another issue.
This is something the developers at oracle will have to fix.
Steve

Yes, you must download and install the 10.2.0.1 version and then patch it up to the 10.2.0.4 version.
http://www.oracle.com/technology/obe/obe10gem/install/index.html
The above link shows you the install routine when using a new database, the steps for the existing database are only slightly different, all you need are the connection details for that existing database and you should be ok.
As for taking full backups of the Grid Control repository, I know many choose not to, space is always a big concern, but this depends on how critical your repository is to you. If you need it for the auditors, well then I'd suggest acquiring some more hard disks to up your space.

Add WebLogic Domain to OEM Grid Control

On a host, say x, i have installed OEM grid Agent Version: 11.1.0.1.0. The host is listed on OEM grid control. On this host i have a weblogic domain version 10.3.3. Now i am trying to add this weblogic domain to OEM 11g grid control which is on a different host.
It gives the following error
Error: Failed to connect to agent x:3872
Failed to connect to agent x:3872. Reason: java.net.UnknownHostException: x.
Only an agent 11.1 or later can be used for finding targets.
How can i solve this?

bummer.. any response? I'm getting the same error now, and the documentation isn't all that clear gasp

How to install OEM Grid Control R2 on RHEL AS4 (AMD64/EM64T)

Hi all,
I was able to install the Oracle Application Server (Infrastructure and BI and Forms) successfully on the another machine with the same specs. The application I installed on the 64-bit machine is a 32-bit Oracle Application Server.
Now, I tried to install the OEM Grid Control R2 (another 32-bit Oracle Software) on an identical 64-bit machine but had no luck. Ran linux32 bash before trying the install.
I always get the error "error in invoking target 'dm_on ioracle' of makefile 'OH/db10g/rdbms/lib/ins_rdbms.mk".
Please help me/guide me in this install if it is at all possible.
Thanks and regards,
Mike

Did you read the installation docs?
Did you look up trying to do this on metalink before proceeding?

Are you doing the Grid Control installation into a new Oracle Home? I would try a fresh installation...Typically, the installation itself is fairly straightforward..

Install of OEM Grid Control on 10g RAC

Hi,
I try to install OEM Grid Control 10.1.0.3 on a 10G 10.1.0.2 database with ASM and RAC installed, on windows.
At the step of choosing the product to install, i would like to choose 'OEM GC using an existing database' or 'Additional management service 10.1.0.3', but it fails.
The reason is 'you cannot install OEM on a hardware cluster'.
I have no idea how to resolve that, do i have to change my RAC installation ?
thank you for your answer,
Isabelle

To install on RAC, you install using an existing database and then specify the sid/hostname for ONE instance in the RAC.
Once the management repository has been sucessfully installed and the mid-tier is up, you can edit emoms.properties to modify the JDBC url the application uses to connect to the database to be RAC aware.
The are a number of pre-installation requisites for an existing database to be used as a destination for a repository installation, there are both documents on metalink on the subject and the basic installation guide references pre-requisites for existing databases.

Adding Database in OEM Grid Control 11g

Dear All,
I have install silently oem agent 11g in a solaris system. The installation was successful and agent is up and running.
But the thing is I can't add this client and its database in my OEM Grid Control interface. When I try to add the target it shows the bellow error
Information
You cannot add a host target from Enterprise Manager Grid Control.
To add a host target, install the Oracle Management Agent on the host computer you want to manage. When the Management Agent begins communicating with the Oracle Management Service, the Management Agent target and the Host target will appear in the list of targets.
My Question is how i can the target's agent can communicate with OMS agent? and How this target can be incorporated?

You install management agents on the host and point the URl to the grid control OMS and it will automatically discover the host and databases
It is in the documentation.

Deploying oem grid control to e bussiness suites

We have installation of EBS R12, the AMP pack for EBS system is installed on the and already running. Now we want to use oem grid control to manage the EBS suites.

The documentation says agent needs to installed on the database tier and application tier and then discovered by the oem
Any idea on how to install the agent on the tier?

OEM Grid control 10.2.0.1 installation using existing database 10.2.0.3

Hi,
I am planning to install oem grid control 10.2.0.1 using existing database 10.2.0.3 for storing repository on HP_UX 64 bit PARISC.
Can it be possible, If not whats the reason and what issues it may arise.
If it possibel can anyone explain me the correct steps and is it compulsory to take full backup(we cant take ful backup bcoz space issues)

Yes, you must download and install the 10.2.0.1 version and then patch it up to the 10.2.0.4 version.

The above link shows you the install routine when using a new database, the steps for the existing database are only slightly different, all you need are the connection details for that existing database and you should be ok.

Enabling security for OEM Grid Control 11g fails

Hi Experts,
One of my Customer is referring the below command to secure OMS and it fails.
emctl secure oms [-sysman_pwd <sysman password>] [-reg_pwd <registration password>] [-host <hostname>] [-slb_port <slb port>] [-slb_console_port <slb console port>] [-reset] [-console] [-lock] [-lock_console] [-secure_port <secure_port>] [-upload_http_port <upload_http_port>] [-root_dc <root_dc>] [-root_country <root_country>] [-root_email <root_email>] [-root_state <root_state>] [-root_loc <root_loc>] [-root_org <root_org>] [-root_unit <root_unit>] [-wallet <wallet_loc> -trust_certs_loc <certs_loc>] [-wallet_pwd <pwd>] [-key_strength <strength>] [-cert_validity <validity>] [-protocol <protocol>]
The error message as below.
Securing OMS... Started.
<May 31, 2011 4:40:31 PM CEST> <Warning> <Security> <BEA-090504> <Certificate chain received from <hostname of the actual node running OEM> - <IP of the hostname of the actual node running OEM> failed hostname verification check. Certificate contained <SLB hostname> but check expected <hostname of the actual node running OEM>
Securing OMS... Failed
The brief background of the wallet creation is as below.
The actual certificate and CSR is created using openssl with a config file openssl-oemgc.cnf. This is according to customer organization's policy and how the production signed certificates have to be requested. The CN is indeed <SLB hostname>. The used syntax was:
openssl req -new -keyout <SLB hostname>.key -out <SLB hostname>.csr -config openssl-oemgc.cnf
The config file content can be referred in the service request.
Following the guide on
http://download.oracle.com/docs/cd/E21764_01/web.1111/e13749/utils.htm#ADMRF151
the certificates were imported into a java keystore 'identity.jks'. And the certificate chain was imported in a java keystore 'trust.jks'.
With these customer has followed note 1278609.1 to configure these keystores in WLS. The certificates show up fine without errors in the browser when opening the WLS console.
Then according to notes 1116717.1 customer has created an Oracle wallet. Then he copied that wallet to an old 10g oracle application server and opened the wallet with 'owm' and saved it. Then he has copied the wallet to the new Oem Grid Control and opened it with'owm' (this now succeeds) and saved it with SSO. This is the wallet that customer is using while trying to secure the OMS.
Service Request: 3-3731274961
Any input is highly appreciated.
Thanks

OEM Grid control 10g on Linux

Hello,
I have installed OEM grid control 10g and able to connect to the console via the sysman user id.
I am trying to configure email notification, but though I put all credentials properly I am not able to receive any emails.
I was looking at Oracle documentation and it says....
The SMTP server is the name of the mail server (for examplemail.acme.com).
For Linux, the SMTP server must be the local host name.Use the fully qualified host name (including domain
Does the smtp server need to on the localhost ? can't it work with a smtp server on a different host than the grid control box ?
Any advice will be much appreciated.
S.

The smtp service doesn't need to be on the host you installed grid control, Grid control can use any smtp server as long as it can reach it.

Gokhan
