Question about Grid Control Agents on a Veritas Cluster (or any cluster)

Hi, I'm seeking advice on how to setup Grid Control agents on a Veritas Cluster.
My cluster is made up of two Sun M4000 servers running Solaris 10 x64 (node1 and node2), and 8 virtual hosts setup to fail between the nodes. Each of these virtual hosts has several mount points from a SAN, and contain Oracle 9 and 10 homes as well as databases. The versions are 9.2.0.8 and 10.2.0.3.
I have a full grid control agent install on each node to mount points that don't fail over to the other nodes. These agents monitor the nodes themselves.
Now for my question, is it better to do full intalls of the grid agent in each virtual host or to use the "emctl deploy agent" from the full installs already on node1 and node2 to the virtual hosts? Or is there some other, better way to do this.
Either method results in 9 grid control agents on a node if all the virtual hosts are on that box. I've experimented with both agent deploys and installs a bit and found that the cpu usage goes though the roof with that many agents on one server. Maybe I don't have them configured correctly, but every now and then they spike cpu usage to 100%, and these servers have 8, dual core processors in them with 32GB of RAM.
Thanks for any tips!
Currently, my setup looks something like this, if it helps:
ORANODE1...........................................ORANODE2
user: oracle..........................................user: oracle
full agent install....................................full agent install
VirtualHost1
user: ora_user1
Oracle 10G Home
repository database
OMS install
full agent install
VirtualHost2
user: ora_user2
Oracle 9i Home
production database
full agent install
VirtualHost3
user: ora_user3
Oracle 9i Home
production database
full agent install
VirtualHost4
user: ora_user4
Oracle10g Home
production database
full agent install
VirtualHost5
user: ora_user5
Oracle10g Home
production database
full agent install
VirtualHost6
user ora_user6

full agent install
VirtualHost7
user: ora_user7
Oracle10G Home
production database
full agent install
VirtualHost8
User: ora_user8
Oracle10G Home

full agent install

Will the agent 10.2.0.3 work with Grid Control 10.2.0.1
Yes.

Security concern about grid control agent

I am planning for grid control rollout. Our system administrator is concerned about
security of grid control agent. For example, I do not know the Oracle password,
I sudo to Oracle after login as myself.
What are the options do I have ? I have told my system admin that
other companies use "oracle" - the database sysdba/software owner as agent owner.
But my system admin think this is a big security risk since he has to tell me the
oracle password

In more explicit terms, what is the security concern you have?
Specifically, I do not see what you mean by the sentence:
when I install grid control agent as "oracle", I provide "oracle "password in order
to run job on our unix server.By "oracle" are you referring to the Oracle Software owner account, by which the Database and/or EM software was installed?
Please explain how the job is related to installation of management agent. If you are talking about running jobs after installation, when agent is configured and running, where and how exaclty are you required to enter "oracle" password?

Question about Grid Control Installation

Hello,
I have two instances of 12i VISION apps with rdbms database 11i running on two different linux systems. I wanted to install 11g grid control to get familiar with the utility.
Do I need to do the install on one of these linux machines or can I install it on a windows client?
I need some help please.
A/A

Hello,
I would suggest install grid control on separate server from rdbms, apps or even client machine
Cheers

Thanks. I do have all of the Templates under Resources in my Virtual Server Pool. However, none of them appear under the Software Components tab. Should they?Not necessarily.
If not, what is the difference between the two? Why don't they appear as Software Components?Software Components = stored in the Grid Control Software Library
Server Pool Resources = stored in the Server Pool's /OVS/seed_pool
So, the Software Components shows you templates that have been stored in Grid Control and these templates can be deployed to any of your server pools (you can have multiple server pools). Once this happens, you'll see the template in both locations. It's a little counter-intuitive, I admit. If you're used to VM Manager, then the Server Pool Resources is the same as what you'd see in VM Manager. Then Grid Control adds the central Software Components option as well.
Does that make sense?

Grid Control agent install fails

Hi all,
I'm trying to install Oracle Grid control agent on linux machine and getting the following error:
./runInstaller

: Success
My /tmp has 1.5 GB of free space so that's really not the issue here. I know that the installation goes well if I use the Universal Installer that comes bundled with 10G RDBMS, but on machines with Oracle 8.1.7.4-9.2.0.5 I wouldn't like to update OUI's because of this issue. Anyone having this problem/solution?
Br,
Anssi

The issue is not about silent install or temp or root.
I have installed Agent on Linux without issues after I read closely the oracle requirements on linux.
Make sure you read oracle linux requirement, there is a patch you need to download that will create proper setting for oracle on linux.
Try look for Application Server 10g installation guide, this patch is documented for Application Server 10g on linux.
The patch will create oracle.sh file that linux will run each time user oracle is activated.
If you still get problem let me know through forum or direct.
Thanks
George

Allow grid control agent to connect to a database as sys with no listener

Hi
I have a database which I would like to monitor using the 10g grid control agent.
the agent and DB are on a Unix Box
The database has a listener, but because it is part of a contingency system we keep the listener shut down
my question is:
Is it possible to configure the agent to connect to a Database (as sysdba) without the listener for that database running?
Regards
Graham
Edited by: Grahambo on May 14, 2009 5:41 AM

No its is not possible if listener is not running

Installing Grid Control Agent and GC repository on UNIX

Hello,
Could You please explain me If I should install Grid Control Agent as separate OS user (different than existing oracle database), or should I place it in ORACLE_HOME of oracle database . I'm not sure how to separate binaries of Agent and Database server.
Moreover same goes to GC repository, should I install it as separate user or in ORACLE_HOME of existing database.
I'm looking for best practise suggestions.
Regards.
p.s.
All Is about the newest versions of the software.

Hello,
Could You please explain me If I should install Grid
Control Agent as separate OS user (different than
existing oracle database), or should I place it in
ORACLE_HOME of oracle database . These are two completely separate things. You o not need to use a new OS user to use a different ORACLE_HOME.
I'm not sure how to separate binaries of Agent and Database server.If you install the whole grid control setup, you put it into a new ORACLE_HOME and the install will give you separate OMS, Agent and database subdirectories.
Make sure the new ORACLE_HOME is from any existing ORACLE_HOME.
Moreover same goes to GC repository, should I install
it as separate user or in ORACLE_HOME of existing
database.Why?
I'm looking for best practise suggestions.Given the special DB initialization parameter requirement, and assuming you do not want to put the repository on a RAC database, I think the best practice is to
1) install Grid Control on it's own machine;
2) install it using the 'complete OMS and Repository' default install
3) add OMS on additional machines as needed for the load.
4) Follow the suggestions in http://download-east.oracle.com/docs/cd/B16240_01/doc/em.102/e10953/toc.htm

RHEL4U4 EM64T Grid Control agent install issue

I've installed a 2 node Oracle 10G R2 RAC on RHEL4 U4 EM64T and it is working fine on Dell PE2850 servers. But I couldn't get the grid control agent installed on these RHEL4U4 EM64T PE2850 servers. The OMS server is running 32 bit Oracle 10g R2 on RHEL4. The issue is with the OMA (agent) install on EM64T and I've tried several different options (local install and push from the OMS server). I end up with the following error. Any feedback is appreciated. Thanks.

Got warnning in Grid control agent deployment

I met the the error message '
PROBLEM : The host name in /etc/hosts is not proper.
WARNING : Check complete. The overall result of this check is: Failed <<<<
RECOMMENDATION : Please verify the hostname is /etc/hosts and the start the installation. '
while I deploy Grid Control agent.
My /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.0.191 ms191.ranfone.com ms191
192.168.0.153 main
ms191 is my OMS SERVER host. main is the target that I want to deploy agent.
I know the hosts should be configured like this .
ip hostname.domain host
however I don't have a domain name . is it neccessary?
Thanks for your kind help.

I have modified my /etc/hosts file and the problem is solved.
and I don't think the localhost.domain line should be commented.
if so, the listener can't start successfully.
anyway. thanks for you reply.

Grid control agent for Solaris 10 x86-64

Are there any estimated release dates for a Solaris 10 x86-64 version of the grid control agent?

This is what I get from the SR...
"Date of availability for the Oracle Management Agent on Sun x64 Solaris 10 is Planned, but not yet available. Estimated date of release has not yet been disclosed. Sorry, there is no further information."
So it's possible to run a database on Solaris 10 x86-64 but there's no grid control agent. Lovely.

Reconfiguing Grid Control Agent on Solaris 8.

I would like to know if I change my IP and Hostname on my Solaris 8 server if I can reconfigure my grid control agent or do I have to reinstall the agent all together?

Hi, i have a machine with 2 IPs and each IP has it's own name registered on DNS. One is the same as hostname and the other one is used as service name for occasion when the production must be moved to another machine with different IP. In that case service name and service IP remains the same.
Is there a way to configure agent on the service IP instead the one registerd with hostname? Or perhaps change hostname in GC configuration to service name?
Because now, i have a situation that listener is listening on interface with service IP, and GC agent can't discover it.
Any help is welcome. thanx.

Configuration of grid control agent 11g

Hello guys,
I have problem with configuration of Grid control agent 11g. Root cause of the problem is that target machine is in DMZ Zone. So there is lack of ports enabled. Other agents I've been installed works properlly.
The one I am talking is able to upload data, but in case of configration I get error message: "Error occurred while getting information for the specified target. Possible reasons include: the target doesn't exist; connection to the target failed."

Configuring the Firewall to Allow Incoming Communication From the Management Service
While the Management Agents in your environment must upload data from your managed hosts to the Management Service, the Management Service must also communicate with the Management Agents. As a result, if the Management Agent is protected by a firewall, the Management Service must be able to contact the Management Agent through the firewall on the Management Agent port.
By default, the Enterprise Manager installation procedure assigns port 1830 to the Management Agent. However, if that port is occupied, the installation may assign an alternate port number.
After you determine the port number assigned to the Management Agent, you must then configure the firewall to allow incoming HTTP or HTTPS traffic (depending upon whether or not you have enabled Enterprise Manager Framework Security) on that port.
As I said already port 1830 was enabled. I did it because I saw that agent status - attached also here.
In case anybody know please tell me who to determine the port assigned to the Mangement Agent...

Grid control agent and data guard in mount mode

Hello,
I would like to know how you manage your data guards when you do not have the license for active data guard with the grid control agents. The standby database is in mount mode, so the agents cannot query the database.
What do you guys do in such cases? Remove the agent? Or wait till a switchover?
