Grid control 10.2.0.3 with DB 10.2.0.4

Hi,
I have installed Oracle Enterprise Manager Grid Control 10.2.0.3 with new database along with the installation.
I also have a Existing database 10.2.0.4 in another server.
1. How can I upgrade my Grid control 10.2.0.3 to 10.2.0.4?
2. How can I monitor/Connect my Existing database 10.2.0.4 from Grid Control 10.2.0.3?
Is it possible to monitor database 10.2.0.4 from Grid Control 10.2.0.3 which is lower version?
Kindly provide the exact document/steps to do the above activities.
Regards,

Thanks for All for replying.
*1. How can I upgrade my Grid control 10.2.0.3 to 10.2.0.4?*
I have upgraded the Grid Control Agent and OMS from 10.2.0.3 to 10.2.0.4
When we upgrade the OMS which also upgrade the Repository database.
Apply the patchset p3731593_10204_Linux-x86-64.zip (Which comes with Grid_Control_10.2.0.4.0_Linux-x86-64.zip)
su - oracle
cd 3731593/Disk1
./runInstaller (Run two times for Agent and oms upgrade)
Agent upgrade_
During upgrade
Specify Home Details: Select the Agent Home to upgrade Grid Control Agent.
Ex: /u01/app/oracle/OracleHomes/agent10g
OMS upgrade+
Specify Home Details: Select the oms home to upgrade oms
Ex: /u01/app/oracle/OracleHomes/oms10g
*2. How can I monitor/Connect my Existing database 10.2.0.4 from Grid Control 10.2.0.3?*
Install Grid Agent on the existing database server 10.2.0.4
Download Linux_x86_64_Grid_Control_agent_download_10_2_0_4_0.zip from OTN http://www.oracle.com/technology/software/products/oem/htdocs/agentsoft.html

Installing EM Grid Control 10.2.0.3 with Database 10.2.0.3 On RHEL4 U3 & U4

Note: This is not an official document, it discusses Oracle Enterprise Manager Grid Control (EMGC) installation on Redhat Linux Update 3 & Update 4 with new database NOT with an existing database. Both OS Updates were installed with FULL PACKAGE INSTALLATION option. Oracle Universal Installer creates the database automatically before creating the EMGC repository.
•     For Linux the base version of the EMGC is 10.2.0.1 and for Windows platform it is 10.2.0.2.
•     The database release is 10.1.0.4 with EMGC 10.2.0.1.
•     When installed it creates three Oracle Homes: 1) db10g (database), 2) oms10g (Oracle Management Service), and 3) agent10g.
Course of Action:
To get to Oracle EMGC 10.2.0.3:
•     Install EMGC 10.2.0.1
 Upgrade Oracle Home oms10g to 10.2.0.3.
 Upgrade Oracle Home agent10g to 10.2.0.3.
To get to Oracle Database 10g 10.2.0.3:
•     Oracle Database 10g 10.1.0.4 will get installed by the OUI automatically
 Upgrade Oracle Database 10g to 10.2.0.1 in new Oracle DB Home.
 Upgrade new Oracle DB Home to 10.2.0.3.
====================================
Installing EM Grid Control 10.2.0.1:
====================================
To install EMGC 10.2.0.1 download all the three files: Linux_Grid_Control_full_102010_disk1.zip, Linux_Grid_Control_full_102010_disk2.zip, Linux_Grid_Control_full_102010_disk3.zip from http://www.oracle.com/technology/software/products/oem/htdocs/linuxsoft.html.
If you have unzipped all the downloaded zip files in separate directories then the very first error message slammed at your face after starting the installation will be something like “OUI-10133: Invalid Staging Area. There Area No Top Level Components”. All you have to do is to unzip all the three files in the single directory (Metalink 395030.1).
After unzipping all the files in the same directory follow the steps that are given on the follow URL.
http://www.oracle.com/technology/obe/obe10gemgc_10202/install/install.htm
BUT the problem is that you will be punched with few other error messages during the installation that will terminate the installation. The WORKAROUND is given below.
There are three stages of the installation by OUI:
1.     Installation of EM Repository Database 10.2.0.1.
2.     Installation of EM Grid Console 10.2.0.1.
3.     Installation of Agent 10.2.0.1.
The first stage completes without any problem and on the OUI you will see: Oracle Enterprise Manager Repository Database 10.2.0.1.0 installed. While installing the Grid Console, during copying files for "Oracle Application Server 10g 10.1.2.0.2" at 90% OUI will pop up an error message "An error occurred during runtime." You will see lines similar to the following lines in the installation log files.
INFO: Calling Action SpawnActions10.1.0.3.0 Spawn

INFO: Exception thrown from action: Spawn
Exception Name: RuntimeException
Exception String: An error occurred during runtime.
Exception Severity: 0
Problem:
There is a bug which is still being worked on by the DEV : Bug 5203165 : Abstract: CANNOT EXECUTE ../oms10g/bin/OracleAs_Relink_Patch.sh AT INSTALL
Note that this is an unpublished bug, not viewable via Metalink. The bug apparently occurs only on RHEL4 (32bit) Update 2 and Update 3 (I faced the same thing in Update 4 as well).
Workaround:
•     Leave the error message as it is and change the execution permission of the script OracleAS_Relink_Patch.sh.
$ chmod +x /u01/app/oracle/product/10.2.0/oms10g/bin/OracleAS_Relink_Patch.sh
•     Now press Retry on the error message pop up window. The installation will resume.
On the same stage while linking at 90% one another error message will pop up “Error in invoking target 'install' of makefile '/u01/app/oracle/product/10.2.0/oms10g/sqlplus/lib/ins_sqlplus.mk'”.
Problem:
Hitting bug : 5203194 :Abstract: RELINK FAILS ON 10.2 GC INSTALL -LIBCLNTSH.SO: UNDEFINED REFERENCE TO NNFGTABLE
Bug is not published in Metalink. As per the description: Installing 10.2.0.2 Grid Control on RHEL4 Update 2 or Update 3 (I faced the same thing in Update 4 as well). This generates an error in the linking phase. The error is generated while attempting to relink sqlplus.
Workaround:
•     Stop installation of all components.
•     Restart the installation and pick the option to resume the installation.
•     This allows the installation to complete.
If by any chance you press continue instead of stopping the installation you should get ready for the garbage OUI is going to throw at you:
Error in invoking target 'install' of makefile '/u01/app/oracle/product/10.2.0/oms10g/network/lib/ins_net_client.mk'

Upgrading EM Grid Control 10.2.0.1 to 10.2.0.3:
====================================
I hope after installing EMGC 10.2.0.1 you are still intending to upgrade it..... :-D Now for that download GridControl_10.2.0.3_Linux.zip from http://www.oracle.com/technology/software/products/oem/htdocs/linuxsoft.html and follow the README.txt file included with the upgrade patch. Before starting the upgrade you will probably have to apply a patch (4329444) on the existing database (10.1.0.4). Anyway, its one of the prereq that you have to complete.
For upgrade follow the steps given on the following URL.
http://www.oracle.com/technology/obe/obe10gemgc_10203/patching/patching.htm
•     Keep one thing in mind that you will have to apply the above mentioned patch twice. Once for oms10g home and once for agent10g home.
•     Stop all the EMGC related services.
•     When applying the patch to a particular home change the ORACLE_HOME to that home. E.g. when applying the patch on the oms10g home:
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/oms10g
and for agent10g home:
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/agent10g
====================================
Upgrading Database from 10.1.0.4 to 10.2.0.1:
====================================
Download the file 10201_database_linux32.zip from http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201linuxsoft.html.
•     Shutdown all the EMGC related services, the listener, and the database.
•     Start the installation of 10.2.0.1.
•     Since 10.2.0.1 is a base release that is why you cannot install it in the existing Oracle Home i.e. in db10g. You have to define a separate Oracle Home for the new installation say db10gR2.
•     During the installation it will ask you to upgrade the existing database 10.1.0.4 to 10.2.0.1, click YES.
•     Hopefully the installation will go just fine.
====================================
Upgrading Database from 10.2.0.1 to 10.2.0.3:
====================================
Download the file p5337014_10203_LINUX.zip from http://metalink.oracle.com.
•     Shutdown all the EMGC related services, the listener, and the database.
•     Start the installation of 10.2.0.3.
•     During installation it will ask for the Oracle Home, give the new Oracle Database Home i.e. db10gR2 and proceed.
•     Hopefully the installation will go just fine.
•     Start the database, listener, and all the EM GC related services:
o     $ORACLE_HOME/../oms10g/bin/emctl start em
o     $ORACLE_HOME/../agent10g/bin/emctl start agent
o     $ORACLE_HOME/../oms10g/opmn/bin/opmnctl startall
•     Try accessing the EMGC through the browser http://xyz.abc.com:4889/em
•     You will see two Oracle databases in the EMGC, the old one, 10.1.0.4 and the new one 10.2.0.3. Don’t worry it will not bother you at all. It will only occupy a GB or so. Though, you can remove it through OUI.
Congratulations!!!! you have now Enterprise Manager Grid Control 10.2.0.3 with Database 10.2.0.3 on RHEL 4 Update 3.
You can repeat the same exercise for RHEL4 Update 4 as well, but during pre-installation checks you will get 1 warning that:
Checking for compat-libstdc++-296-2.96-132.7.2; found Not found. Failed <<<<
Checking for libstdc++devel-3.4.3-22.1; found Not found. Failed <<<<
Checking for openmotif-21-2.1.30-11; found openmotif-2.2.3-10.RHEL4.5. Failed <<<<
Actually, these packages are already there in the OS but the higher versions. It is evident from the above messages that first it “founds” the package but due to the version conflict it says that “Not found”. All you have to do is click on the check box next to warning, it will change to User Verified or something. Now press Next and follow the same steps that we followed for Update 3.

The quicker way is to use sofware only method to install 10204 oms and dirctly use 10203 datbase directly as a oms repository.

Patching new install of Grid Control 10.2.0.1 with 10.2.0.4 fails

I just installed 10.2.0.1 Grid Control including standard repository. I want to install 10.2.0.4 patch. After successful installation, I shut down OMS and attempt to run the patch 3731593 which is the 10.2.0.4 patch. Only the listener and repository are running. OUI pops up a message box saying there are background dbms jobs currently running and to wait for them to complete. Message suggests I execute SQL procedure emd_maintenance.remove_em_dbms_jobs to stop all running jobs. This results in message 'emd_maintenance.remove_em_dbms_jobs' must be declared error. It says try select count(*) from dba_jobs_running run_job (etc) which I run and it shows 1 job is running. How do I stop this job? I tried rebooting and then just restarting the DB and listenener and the error remains. Still says 1 job is running and I can't install the patch!
The standard DB installed with GC 10.2.0.1 is 10.1.0.4. Do I need to patch that first to a later version? Should I just give up and uninstall and start with a fresh install of a later version of the database and then install Grid Control using an existing DB? I want to use this for provisioning.
thanks for any helpful hints.
Carolyn

Hi Carloyn,
I have recently installed grid control, and its all fine.
I would say you uninstall everything
Install again 10.2.0.1
at the time of patching make sure everything is shutdown, agent, oms and repository
It will be fine.
to upgrade the repository database from 10.1.0.4 to 10.2.0.3 is optional. I have not yet upgraded it, my argument is that oracle docs says that the upgrade is optional and if it would have been important, oracle would have incorporated the upgrade.
So I would say, leave it alone.
I would also say that installing database first and then gc might not be a very good idea.
feel free to contact me at [email protected]

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..

Configuring Grid Control on 10g R2

Hi
Current Envt : Oracle 8.1.7/Win NT.
We are going migrate to 10g R2 ,
In the current 8i environment, we have a EM database which manages RMAN backups of a couple of Other databases.
And we monitor these backup jobs through this Enterprise Manager 2.2.
Also, using this OEM 2.2, iam able to monitor all the existing databases .
Coming to 10g R2 (10.2.0.1)
i realized that Enterpise Manager (web based) is only for a single instance.
And i read some where that 10g Grid Control would be helpful for multiple databases.
and how to access the Grid Control..and configure multiple databases on it.
Currently, i installed Grid Control 10.1.0.5 by giving the path as
E:\app\oracle\product\10.2\em_1
However, iam not able to figure as how to bring up the Grid Control.
I wanted to know if someone can provide the steps on how to install (if i have been doing anything wrong ?
Whether while installing i have to give the same $ORACLE_HOME as with the database ?
I also tried the same way as regular DBcosole ie., http://localhost:port/em
In addition, while creating the DB using DBCA, i selected the Grid Control Option.
Please suggest as how to proceed further.
Thanx

See comments below:
Coming to 10g R2 (10.2.0.1)
i realized that Enterpise Manager (web based) is only
for a single instance.Database control is for single instance and it gets when you install the database provided you pick the option to install it.
And i read some where that 10g Grid Control would be
helpful for multiple databases.Grid Control is the only way to manage multiple dbs.
and how to access the Grid Control..and configure
multiple databases on it.
Currently, i installed Grid Control 10.1.0.5 by
giving the path as
E:\app\oracle\product\10.2\em_1Install Grid Control on a separate server preferably one dedicated to management only. Then on each database server, you'll need to install an agent for OMS to talk to the target database.
However, iam not able to figure as how to bring up
the Grid Control.
I wanted to know if someone can provide the steps on
how to install (if i have been doing anything wrong
Whether while installing i have to give the same
$ORACLE_HOME as with the database ?Install as I said above. In a separate home if you want to install it on a server that has your target database.
I also tried the same way as regular DBcosole ie.,
http://localhost:port/em
You probably didn't install the DBconsole.
>
In addition, while creating the DB using DBCA, i
selected the Grid Control Option.
For this option to work, you need to have Grid Control operational. First start with selecting only DBConsole...this way you can manage your database. After you get Grid Control installed and the agent is working properly, you can stop the DBConsole service and use Grid Control to manage your target database.

1st attempt to install GRID CONTROL

I am on an HP-UX ITANIUM box and have been told by Oracle to install the general HP-UX Grid Control installation. After reviewing the documentation and from my last class I learn that ORACLE MANAGEMENT SERVICE must first be installed. I have waded through the listed downloads to the following pages:
www.oracle.com/technology/software/products/oem/index.html
and
www.oracle.com/technology/software/products/oem/htdocs/hpsoft.html
both pointing to OEM 10g Grid Control r2 for HP-UX with a README attached.
I have downloaded the 6 HPUNIX_Grid_Control_full* zip files and went to read the indicated README hoping to see installation instructions or at the least WHERE on the HP to place these files - README goes to an ORACLE NOT FOUND page.
Can anyone assist me in obtaining the installation instructions?

Thank you
Ravi Rangas (Oracle Business Development Consultant) assured me that the Oracle Enterprise Manager 10g Grid Control Release 2 (10.2.0.1) for HP-UX (six HPUNIX zip files) found at www.oracle.com/technology/software/products/oem/htdocs/hpsoft.html were the downloads to use for HP-UX ITANIUM.
I executed the installer and when it reached the point "Linking "oracle Net Required Support Files 10.1.0.2.0" errors began to generate from the make files (example: warning: the file no.o is from an incompatible architecture). This tells me that the install set I was assured would work on ITANIUM in fact will not.
Do you have a recommendation on the correct HP-UX ITANIUM installs?

A possible bug for Grid control?

Hi, Dear all,
We installed Grid control 10.2.0.1 on Redhat Linux R3 with existing database(10.2.0.4).
During the installation, we succeeded for repository creating but failed at OMS Configuration.
When I start oms in cmd line, I got the following error: the repository database can not be connected.
The description for the environment:
1. OMS server and repository database are installed on the same server, on which HA is used.
2. There are two floating IP on this machine,
IP | server name | used for |
xx.xx.xx.124 | cnsz030318 | oms server |
xx.xx.xx.80 | oem.db.paci.com.cn | repository database |
3.When we installed the oms with OUI, the repository server we input is oem.db.paci.com.cn
The problem we found:
During the installation, the repository was created successfully. But it failed at OMS configuration.
The error we got: the repository database can not be connected.
there are two lines in emoms.properities which seems strange:
oracle.sysman.eml.mntr.emdRepServer=oem.db.paic.com.cn
oracle.sysman.eml.mntr.emdRepConnectDescriptor=(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=cnsz030318.db.paic.com.cn)(PORT\=1535)))(CONNECT_DATA\=(SID\=oem10g)))
The emdRepServer is what we have input on OUI:oem.db.paic.com.cn. But for the connectDescriptor, it is changed to "cnsz030318.db.paic.com.cn", which does not exist at all!.
Now, we have worked around this problem by adding "cnsz030318.db.paic.com.cn" in the /etc/hosts.
But my question is, why the connectDescriptor set the HOST\ as cnsz030318.db.paic.com.cn? Why does it not use the name we input in OUI (oem.db.paic.com.cn)?
Maybe it is a bug for Grid control?

Did you install with "Use existing database" or "Use new database"?
I recommend that you use fully qualified domain names only!

Oracle 10.2 Grid Control – Adding Database residing on different hosts

I used to work with Oracle 9.2 Enterprise Manager. Now I have installed Oracle 10.2.0.2 Grid Control on Windows 2000. I want to do database administrator from Oracle Grid Control for Oracle 9i, Oracle 10.1 and 10.2 databases. I do not want to install any agents on my database servers because they are production servers,
All of I am interested in to have nice user interface of Oracle 10g grid control, so I can do database administration such as adding a database file, looking at database users, sessions etc. I was able to do all of that with Oracle9i enterprise manager. IN Oracle9i EM, one can manually add a database instance if it cannot be discovered using an agent. Is it possible to do that in Oracle 10g grid control?
When I start Grid Control, go to targets tab and then database tab and want to add a database, it asks for host name. When I enter hostname (which is accessible from the network), it says host not found. Is an agent required on the host before Grid Control can recognize it. In Oracle 9i enterprise manager, there was an option to manually add a database (i.e. automatic discovery was not successful), is it possible to do that with Oracle 10g grid control.

Over the years, working with Oracle, I've found tremendous value in reading the docs. You might find similar value doing that too.
The only issue you seem to have is an unwillingness to learn the architecture and concepts behind the product you are trying to install. You get rid of the error by deleting the entry and doing it correctly.
There is no way to drop a brick on your foot and not have it hurt. <g>

Grid Control and Ora-12557 error

Hello, I'm trying to install the Oracle DataGuard in my work. I have two server with these features:
2 Processors Intel Xeon 2.8 GHz
4 GB Ram
6 SATA hdd 250GB (Raid 5)
for each server. Actually, only one server have the database production, and the another server I have for testing purpose. I must be have a high availability system. I want to build an Oracle RAC system, but I think that I need an external storage (something like SAN, or fibre channel or iSCSI). Well, I assumed that I don't create a Oracle RAC because I do not have the hardware requirements. Then, I thougth use Oracle DataGuard. For that, I have one server in one building and another server in another building like a standby database. If a server fail, then I use the another.
I decided to create Oracle DataGuard configuration. I installed windows 2003 server standard edition in my server for test purpose, and then I installed the Oracle Database 10 g with my database. After I installed the Oracle Grid Control with a new database for repository. Well, when the installation of Oracle Grid Control was completed, I didn´t connect to my database because sqlplus show me an error (Ora-12557). Before I install the Oracle Grid Control I can connect perfectly with my database, but after that I can not connect any time.
Anyone can help me, please????

After formatting (clean server)
1. Install grid control Repository and Management Server
2. Patch it to the latest version (10.2.0.3)
3. Install agent on your other server ,see that you should be able to communicate, check for propert username/password settings.
4. Install your first database , lets say you install it on the same machine with grid
Check for ports/etc and see its in a working order
5. From Grid control ,create your standby on another machine , grid required no interfearance from user once some pre-requisits (you should be able to ping/ftp) on the host.
there are number of possibilites for meeting your requirements, keep refering installation guide where possible.

Grid control switchover issue

Hi,
I have carried out the following
a 10g database install on 2 servers
enabled dataguard between them so I have a primary and a standby database.
I then installed Grid Control onto each server using the opetion to install into an existing database. this worked.
On the standby server opmnctl is shutdown and the database is a PHYSICAL STANDBY.
when I do a dataguard switchover I see the standby database is now the primary. I restart opmnctl and go to the web browser to look at Grid Control.
The issue I have is that Grid Control, even though it is on the standby server, points to the primary server. How can I change this behaviour
When I first started Grid Control I had to perform the following actions
[oracle@griddg bin]$ ./emctl status emkey
Oracle Enterprise Manager 10g Release 3 Grid Control
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
Please enter repository password:
The Em Key exists in the Management Repository, but is not configured properly or is corrupted in the file system.
Configure the Em Key by running "emctl config emkey -repos".
[oracle@griddg bin]$ ./emctl config emkey -repos
Oracle Enterprise Manager 10g Release 3 Grid Control
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
Please enter repository password:
The Em Key has been configured successfully.
after this gridcontrol was able to start but points to the wrong host.

hi,
the steps I took are as follows
1 - precreate a database on the primary and standby.
2 - configure the tnsnames and listener files so that the databases can talk to each other
3 - create a standby control file from the primary database.
4 - copy all database files from the primary to the standby
5 - copy the standby controlfile to the standby
6 - start the primary database
7 - start the standby database but only mounted, check database_role from v$database; it should be physical standby
8 - install Grid Control on the primary server with the option to install onto an existing database. Complete this installation.
9 - Install Grid Control onto the standby server with the option to install onto an existing database. Complete the installation and then carry out an 'opmnctl stopall'
10 - all being well Grid Control should now show both hosts and databases.
11 - create a dataguard configuration from within GC
The standby database cannot be discovered correctly in GC and this must be because it is in a mount state, not sure what to do about this. This then meant that I had to carry out a switchover from the command line. I am just testing this now and will post back when complete.

Grid Control 10gR2 on RHEL4 x86-64

I've been asked to install Grid Control on a RHEL4 box with a 64bit architecture. Is this at all possible as I've not found any documentation or forum threads to support this?

I've been asked to install Grid Control on a RHEL4
box with a 64bit architecture. Is this at all
possible as I've not found any documentation or forum
threads to support this?I was just in class last week for Grid Control at Oracle HQ (Belmont, CA). We had 6 Customers and 9 Oracle employees. There was someone there from the Oracle on Demand site that was very good.
Three things I can say:
1) Apply the 10.2.0.2 patchset and follow the instructions exactly as the doc says. This was very helpful and has been recently posted on OTN.
http://www.oracle.com/technology/obe/obe10gemgc_10202/patching/patching.htm
2) Do attempt to upgrade the DB from 10.1.0.4.0 to 10.2.0.2.0. After sometime the database will become corrupted.
3) Everything, but the OMS is supported on 64-bit RHEL 4. Even though the 32-bit binaries are there, it might work, but you more than likely will struggle to get it to work.
There was an Acct. Rep there from the eastern office and he said that the 64-bit version of EM(GRID) will be coming out in 11g (~12-18months) and will not be backported.
We have our install on 32-bit RHEL 4 on 64-bit hardware. Not a popular choice, but it will give you an upgrade path in a couple of years.

Install grid control agent 10.2.0.5 on VM Server?

Hi:
I'm using Enterprise Manager Grid Control 10.2.0.5 with the Virtual Server extensions and it is working fine. However, I've noticed that my Virtual Server machine (dom0 -- not the guests) does not show as a host on my Targets tab.
One drawback to this is that I've tried to import the templates that already exist in my Seed Pool into the Software Components tab of my Virtual Servers tab. It has an option to find a Host, but the only hosts lists are those that have Grid Control agents on them.
Is this expected behavior?
Would it be beneficial to install the Grid Control 10.2.0.5 agent on my VM Server 2.1.5 so that I can load the templates into the Software Components tab?

pasinc wrote:
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?

Oracle Grid Control 10.2.0.3 can´t configure databases

I installed the Grid Agent (10.2.0.5) in host1 for monitoring the database (10.2.0.5) inside him. I did the same in host2, that has Agent (11.1.0.1) and Database (11.2.0.2). Both Agents are pointing to the same Grid Control Management Server.
Grid control has a separated server with Grid Control OMS and Agent installed (10.2.0.3).
This host1 was added to the grid control target hosts, and the database too. The secure option is disabled.
First Problem: metrics collection error in Grid Control for database target.
My Solution: Deconfigured the Oracle DBControl in host1 and host2 (it was configured with a local repository) dropping the repository, and I used | emca -config agent | to create a link to the agent in local machine.
New state: Now the OEM show the targets apparently been monitored. When a target fall down the OEM send allerts normally.
Second Problem: When I click in a host, database, listener, or any of the targets, intending the log in the instance it take about 5 minutes and returns: "No Response from Application Web Server There was no response from the application web server for the page you requested. Please notify the site's webmaster and try your request again later. "
My solution: I didn´t find one. HELP!
For coincidence, all databases actually monitored (8) are 10.2.0.4 or down. All of these can be managed by click in target names by OEM. Could it be the version of the new databases?

Hello.
We already have Grid Control 10.2.0.4 and just installed AD4J 10.2.0.4. This version of AD4J is not integrated with Grid Control, and can be setup on any server by unzipping the downloaded file (no installer). I did find the installation/configuration documentation lacking, but worked through it with a little help from Oracle Support.
The AD4J console has the look and feel of Grid Control, but is totally separate app with its own Apache server, etc.

OMS error during install Grid control 10gR2 on Windows 2003

He,
I get this error during install Grid control 10gR2 on a new server win2003.
"oracle.sysman.emcp.agent.AgentPlugIn"
What I see in forums is that I have to stop my listener and continue my installation.
But I still have the same error !!
Can you please help?
Many thanks

There are some guidelines here:
Subject:      OracleAS Install Error When Configuring AS Console Agent - "oracle.sysman.emcp.agent.AgentPlugIn has failed"
     Doc ID:      Note:386308.1
The solution stated is "Check the contents of the hosts of file and ensure that every entry is correct. All hostname / ip addresses have to be valid."
When installing AS 9i R2 there was an issue with the names, those were supposed not to hava a hypen, so may be something was inherited from those kernels.
There is another metalink note that document hosts issues:
Problem: AgentCA: Grid Control Release 2 install fails with java.lang.Exception: 6 during Agent Configuration Assistant

JBOSS Plugin for Grid Control 10.2.0.5

Hi,
I have configured two 4.2.2 JBOSS instances in our 10.2.0.5 grid control. In one JBOSS instance the application is deployed as an EAR file and in the second the application is deployed as a WAR file. The JBOSS instance using the EAR file does not show our EAR file under the Applications link in Grid Control, whereas the JBOSS instance with the WAR file correctly shows our WAR file in the applications link.
Are there any restrictions with the JBOSS plugin and EAR files?
Thanks
Mark

If you have DNS to resolve the host name and ip-address of the OMS server from the agent server thats ok. And the same goes for resolving the host name and ip-address of the OMS server from the server where the agent is installed.
You say it works now. So you have DNS working, and the OMS - agent connections work fine? Right? No need to add extra entries in the hosts files.
The note should probably say: if you don't use DNS then you should add the entries in the hosts file.
