Grid control on virtual environments

We have a fairly small grid control setup, currently all components sit on one physical machine.
We are looking to put the latest version of grid control, application+database layers on single virtual machine.
I'm aware of Oracles' support policy to VMWare virtual environments but am just wondering if anyone has had any experience of this or has any recommendations either way as to whether this is viable plan.
Thanks for any input.

I ran it on a Production VMWare-Linux environment: no issues. Now I am running production under VMWARE-Windows: also no issues.
The only problem Oracle support can make if you run into a new bug. They can say that you first have to prove the bug also exists in a non VMWare environment. The change that will ever happen is small. And even then you can temporarely V2P your server.

Grid Control 12c and high availability databases

Hello,
In the context of high availability databses, my configuration is as follow:
2 AIX servers on 2 sites with shared storage -> Site1 and site2.
During normal operations databases are on site1. In case of disaster, databases can fallover on site2.
On my Grid Control, 2 agents are installed: One for AIX on site1 and one for AIX on site2.
Databases have been discovered on AIX:site1
Listener is a virtual address and can also fallover.
What are the possibility on the grid side ?
Do I have to discover also the databases on site2 ?
Actually, Listener is seen down on the site who has not the databases.
Is there a way to only configure the Listener virtual address on the Grid ?
Regards

Hi,
Basically you have to relocate the targets to the new agent (the one installed on site2). I haven't done that, but I expect to work fairly easy and smooth. Refer to the following section of Cloud Control 12c manual:
Configuring Targets for Failover in Active/Passive Environments

How to figure out server has capacity to install OEM 10 Grid control

How to figure out server has capacity to install OEM 10 Grid control
Hi Experts
I have HP_UX 11.11 server which has 1 instance on it with version 10.2.0.1.0.
Now I would like to install Grid control with a separate instance for repository.
I was told I would need 2 GB Ram for OMS and 2 GB Ram for instance.
Now how do I figure out if my server has enough resources from Ram perspective
Following is output from top and vmstat
1. for top it says 3045556K free , now is this free memory virtual(real +swap) or real?
2. as per top I only have free 3GB(3045556K) , so does that mean I can not have OMS & repository on
this server ?
3. In vmstat I see free memory as 762335
in man it says free - Size of the free list
what does this mean, how much is my free meemory ?
4. For OMS I read - It is a J2EE application that is installed and deployed using Oracle
Application Server
Now when I look at top I see these processes
0 ? 26521 oasadm 152 20 1517M 1141M run 3:49 2.53 2.52 java
0 ? 3377 oasadm 152 20 1657M 1276M run 54:49 1.88 1.88 java
Does oasadm user means Oracle application server ? If yes does it mean I will not
need 2GB for OMS ?

how much is my free meemory ?Do you have kmeminfo command installed?
4. For OMS I read - It is a J2EE application that is
installed and deployed using Oracle Application Server
s oasadm user means Oracle application server ? If
yes does it mean I will not need 2GB for OMS ?Even if that java vm is an instance of Oracle AS (OC4J), the Grid Control installs a separate instance of AS. The choice to install OMS app to any existing AS home does not exist in any version I know.
Find out what more is running on the box and how much resources (i.e. RAM) those apps are configured with.

After adding a logical standby database through Grid Control for a RAC database, I noticed sometime later the Data Guard configuration disappeared from Grid Control. Not sure why but it is gone. I did notice that something went wrong with the standby creation but i did not get much feedback from Grid Control. The last thing I did was to view the configuration, see output below.

Has any body come across a similar issue?
Thanks,

Any resolution on this?
I just created a Logical Standby database and I'm getting the same warning (WARNING: No credentials available for target ...) when I do a 'Verify Configuration' from the Data Guard page.
Everything else seems to be working fine. Logs are being applied, etc.
I can't figure out what credentials its looking for.

EM10gR2 Grid Control / Change Management Pack does not support TYPE objects

I wonder any Oracle EM10gR2 Grid Control users, implementing Oracle Change Management Pack, have used it for the release and proper packages management.
Issue1 - On an EM console / Web GUI the DDL comparison and synchronization is not supported at all. Implementing it @ customer it appeared that we have to install a 10g Java Client in order to use the code comparison and sync functionalities.
Issue2 - and this is more serious - it appears that even with Java client in use, you cannot compare or sync objects related to TYPE or TYPE BODY data types. The comparison simply hangs.
Asked help from support, they mentioned an ER from 8i and logged a new ER for 10g/11g. That is surprising especially as the doc (http://download.oracle.com/docs/html/A96679_01/toc.htm) about code comparison does not exclude the TYPE objects from the supported options.
Any fellow DBA running to a same problem? What solutions & recommendations might you have?

Hi Mugunthan,
Can you provide links to any tutorial or example (screenshots) of using Setup Manager to transfer something between two environments (say Users or DFFs)?
Thanks,
Gareth

Functions: Oracle VM Manager vs. Grid Control Oracle VM Management Update

Hello guys,
i have seen both tools .. and i have to say that some really basic functions are missing in the Oracle VM management addon for Grid Control 10.2.0.5 .. just some examples:
- Renaming virtual machines (because of the prefix syntax is not very useful)
- Adding ISOs as CD/DVD after removing them one from the profile (until now you need to know the whole path to the DVD, even if the ISO is registered in the repository)
- Renaming image files (for example the disks of the VMs .. this would be very helpful in case of cloning machines)
- List the VNC port for the running VMs
All these features are available under the VM Manager (except the renaming file part) ... do you know when this will be implemented or is the Oracle VM management update already "finished" in its functions.
Regards

Hi,
You can manage your Oracle VM environment using Oracle Enterprise Manager 12c. Using Oracle Enterprise Manager 12c you can discover Oracle VM Servers, discover storage servers and file systems, create and edit server pools, set up networks and create storage repositories.
for more information, look at this URL.
I hope this can help you

Grid Control : Change Management Across Non-Prod and Prod

All,
I had some questions with regards to Grid Control Implementation Architechture on Prod and Non-Prod Env's
The best practice is to configure a production Grid Control (GC) environment to monitor only production targets. This prevents nonproduction targets from adversely impacting a production environment.Another issue could be the compliance policy where in the production systems are to be isolated from Non-Production Environments.
If this is the case then we have to have 2 GC environments , 1 for Prod and 1 for Non-Prod. In such a scenario how well can we do change management (Version control ) across the Non-Prod and Prod Environments ?
To be more specific
How is version control managed for Oracle builds if we have separate GC for Prod and Non-PROD? (Change Management pack / Configuration Management Packs are there but what is the real depth of these? )
Change management for the Oracle Environments from DEV -> Test -> Pre-Production-> Production? We aim to have consist build across the environments can we achieve this if the GC is managed by Different OMS/OMR and if we have 2 separate environments how do we sync the GC environments managing PROD/NON-PROD after a change?

This is feature is not there in 10.2
This situation can be avoid by chagning the 9i port to 1522
or install the GC on diffrent box

Installing Oracle10g Grid Control - - - management service hostname

Oracle 11g R1 RHEL 4 64bit
Grid Control 10.2.0.4
HI All,
I am installing the Oracle agent and when I get to the 'Specify Oracle Management Service Location' screen it asks for the 'Management Service Host Name'. Is this the same as my database server hostname? I'm not sure what to put here. When I do put the database server hostname in, then it says it can't locate port 4889 on that server. However, if you keep going through the install everything succeeds in the end. BUT, when I go to the link http://<management_service_hostname>:4889/em then nothing shows up. I am new with grid control. Anyone have any ideas?
Thanks.

Great. Thanks for your reply Bobcatalog!
Now I just want to get this all cleared up before I proceed with the installation. So here is what I am thinking of doing and please tell me if I am wrong, missing something or should do it another way.
1. Install OEM Grid Control 10.2.0.3 on a new host (server) which has nothing on it (i.e. no Oracle products - - - clean host) and then patch it to 10.2.0.4.
- I will use the create new database option, which will create the EM Repository database
- I will (or it will) install the OMS as well as the OMA (Oracle management Agent)
(Question: Should I install OEM Grid Control on just a regular filesystem or use ASM with it? I heard that there are issues with using ASM. If it will increase my chances of failure, then I will stay away from it...even though all our environments (DEV, PROD, QA) use ASM.
2. Install the OMA agent on each of the database servers (which are called 'targets') that I want to monitor.
And that is all that I will need to do, correct?
Thank you.

Grid Control showing excessive amount of disk utilization.

Hi Folks,
I understand that Oracle doesn't support their products 100% on non Oracle VMs, but I thought I might take a stab at it.
I decided to stick with a simple installation of Oracle Grid Control running on a Windows 2003 R2 32 bit os, here are the steps I took.
1. Run Guest OS Windows 2003 R2 32 bit on a Windows 2008 x64 running Hyper-V (Yes I know why not EL5 running XEN, long story)
2. Install Grid Control with Database and Agent versions 10.2.0.2.1
3. Patch agent and oms to 10.2.0.5.0
4. Some minor issues, but managed to get by those.
- First off EM Website shows down, got to take a look at that, probably need to fix the beacon, not sure!
Problem:
- Grid shows that the host running em is over 100% disk utilization.
- According to Metalink this is a known bug in Windows 2000 Performance Counters (not 2003?)
- More specially Microsoft KB article Q310067.
- Metalink Doc Id: 303788.1
- Note, I'm running 2003 on a Hyper-V Guest, so anything can go wrong!
The specific error is:
Metric               Disk Device Busy (%)
Disk Device               0 C:

More info:
- Guest is running on a Dual Quad Core Xeon System with 16 GB of RAM
- Guest has dedicated 4096MB of ram
- Guest has dedicated 2 CPUS
- Guest is configured with a Virtual Disk (specifically partition c:\) to be on local Hyper-V disk array
- Windows 2008 Hyper-V host disk array is in a RAID 5 configuration running 10k SAS drives
- Windows 2008 Hyper-V host utilization is literary at most 5% (current is 1%)
- Windows 2008 Hyper-V disk utilization according to graphs is showing 100KB/s usage (less than 1%)
Temporary solution is to turn off the metric, but not sure if that's such a good idea.
- Note that 11g EM and 10g EM running on Hyper-V server had the same issue.
- Note that 11g EM and 10g EM running without visualization had no issues.
Any thoughts?

It may be related to Bug 8677212: BACKUP INFORMATION FOR SOME DATABASES SHOWS INCORRECTLY
Although bug info says it for HP-UX, I've also seen the same problem on Grid Control 10.2.0.5 running on Solaris.
You may want to apply 10.2.0.5.4 Grid Control Patch Set Update (PSU) [ID 1139563.1] to fix it.

Grid Control 10.2 and Port 1521

I'm installing Grid Control on a HPUX box that has three Oracle Financials environments, and four non-financials databases. During the install, I'm asked to run a script as root. On that same screen, it says "in order to successfully install the product, any applications other than the 10g database listener running on port 1521 must be stopped". I have a 9i DB running on 1521 - for our PROD Financials. I stopped the install of the grid, not wanting to mess anything up.
My questions - is there a way to specify a different port for the Grid control? Is anybody else in the same situation as me here? What do you guru's recommend I do? I'm thinking I should install the grid control on a separate box.
Thanks...cjj

This is feature is not there in 10.2
This situation can be avoid by chagning the 9i port to 1522
or install the GC on diffrent box

Creating standby database through Grid Control.

Hi,
I want to know if source database which we term as primary database goes down during Db creation process when given option of "Perform a live backup of primary database" during Add standby wizard in Grid Control. Please let me know if people have already tested it in their environments.
I appreciate you all for looking into my forum.
Regards,
Gaurav

No, one of the options for performing this task is to create from a Live db.
A couple of things to note here:
You must be using spfile
If you are not using the default port of 1521 then you must also have the local_listener parm set
I recommend using the "db_unique_name" option to make it easier to manager in OEM (for the target name)
Hope this helps,
Landon

Is 10g Grid Control compatible with database 11g R2?

Hi all,
I've searched the certificaction matrix for Grid Control in Metalink and it shows the last compatible version of database to create the repository is 11.1 also I don't know if it could monitor a 11.2 database...
If I try installing it the usual way I get an error of invalid version and if I use the silent mode, I get stuck always on an error, so I suppose, for the moment, it's impossible.
Any of you have had some experiences like mine?? I planned to use it for administering Data Guard...

if it could monitor a 11.2 database... It can monitor, at least the basic functions,I added a 11gR2 database to the monitored targets (more exactly the agent discovered it properly). New features (and there some for dataguard,too) aren't yet covered. And it's not supported. 10g isn't very specific,I'm talking about the latest release 10.2.0.5 running on Windows Server 2003,not sure about lower versions.
Because of the lack of official support, I wouldn't yet include 11gR2 databases in production environments.

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.

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...

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

Will the agent 10.2.0.3 work with Grid Control 10.2.0.1
Yes.

Trouble with 10g after Installing Grid Control

Main problem: after installing Grid Control and rebooting, I can no longer access my databases.
I have 10g installed on a fairly decent Windows XP machine. It was running okay, but I had two Oracle database instance processes running at 200mb of RAM each (of a total of 1 GB of RAM), so it was a bit bogged down, as is to be expected when running Oracle as a server on Windows.
I then installed Grid Control, which seemed to go okay, and another database as well. But once the install completed, and I gained access to the Grid Control version of the OEM for the first time, that's when things got wacky. Connecting to any OEM instance started taking anywhere from 2-10 minutes, everything was bogged down considerably, etc. I tried shutting everything down and rebooting, but now things are worse. OEM is timing out and not finding servers, listener is timing out, etc. I've tried manipulating a few things in Net Manager (I noticed that my LISTENER section didn't seem to contain any data at all, and my databases weren't listed in there either) with no result.
I've also had trouble with "host credentials" and being able to administer the databases within the OEM, even after implementing a fix I had found to add my user name to a "log on as batch job" local security policy.
Finally, I noticed that after installing Grid Control, when I run "sqlplus", I now see "Oracle91 Enterprise Edition" instead of the "Oracle10g" it used to show (and I never had anything but 10g installed on this machine!).
Here's what happens when I try to access my dBs:
-When I try to launch the OEM connected to any of the 3 databases I created (which were previsouly running), the browser just times out with "page cannot be displayed".
-When I run "emctl start <ANYTHING>" I get file/path not found errors, and a file path with both forward and backward slashes (starting after the "agent" directory):
C:\oracle\product\10.1.0\agent/<...etc.>
-When I try to test a connection to a service in Net Manager, I get this error:
ORA-12557: TNS:protocol adapter not loadable
I had to manually add my listener info and databases info(under Service Naming) in Net Manager, but everything appeared fine in Oracle Directory Manager (unfortunately, that doesn't help much, since this is just a general info tool).
I am nothing near a DBA and my knowledge is limited, so I apologize for not being more consise, but I'd be glad to elaborate if someone could tell me what they need to know.
Thank you,
John

Yes; thank you both. Although I had 1 GB physical and 1.5 GB virtual memory configured, running Grid Control seemed to completely kill all available resources.
I have removed GC and its related database and applications, and I can again conncet to my databases via Database Control. Thank you.
By the way, another issue has arisen, seemingly in the aftermath of installing GC: my OEM Database Control instances now time out after about 60 seconds, logging me out each and every time. I have cookies enabled, but this doesn't seem to be the trouble. Is there a Web setting somewhere that will kick users out of the instance at timed intervals?
