OMS unable to reach host in 10g grid control

Greetings Gurus:
I installed oracle 10g grid control r2 and agent on a windows xp machine. on another windows xp machine i installed the agent. i am able to see the host in grid control on the machine with the grid control installed but cannot see the remote machine with only the agent installed. i have reloaded and uploaded, started and stopped the agent using emctl and opmnctl without any issues(this is on the remote machine) but still cannot see the remote host. when i try to secure the agent on the remote machine i get the following:
Requesting an HTTPS Upload URL from the OMS... Failed.
The OMS is not set up for Enterprise Manager Security.
I am fairly new at using grid control and standby database and have had a torrid time trying to fix this problem. your assistance would be greatly appreciated

*1. Stop dbconsole*
emctl stop agent
OR
emctl stop dbconsole
*2. Secure it*
emctl secure dbconsole sysman_pwd agent_reg_pwd
*3. Start dbconsole*
emctl start dbconsole
*4. After some time when the dbconsole starts check the status*
emctl status

Unable to connect to Database using Grid Control

Hi,
I am attempting to connect to my Oracle Linux Machine which has 2 databases FROM my 10g Grid control which is on a Windows XP 32 bit.
Although I can login to the actual linux box with the host and database credentials ; I cant use the same to login to the database using Grid control.
I have tried testing the connection using Grid Control >> Preferences >> Preferred Credentials >> Host ; but its just not recognizing the credentials as correct.
When I attempt to startup the database using the host and DB credentials : ERROR MESSAGE : <servername> : <servername> comes up.
My agent on linux box is up. My Listener is running fine.
On my Grid control .. i have the DB, OMS, and Agent running as well.
Any inputs on this issue, I'd appreciate very much.

Thanks for your reply.
Under Hosts on the Main Grid Console Home Page >> "server3.sam" Status shows UP. This server houses my 2 databases. But when I click on Databases >> it shows Instance DOWN.
Status
Failed
Details Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
I have verified that my lsnrctl status is good on the linux box. My target agent is up and running on it as well.
So I try to start the STARTUP button >> I enter the HOST Credentials of the Linux box and the Database credentials which I use "SYS" (in upper case - just in case that mattered) and choose SYSDBA ;
Error Message
server3.sam: server3.sam
I created a new dba account and try to login ... dont seem to work ; I tried using SYSTEM account and even altering my sys and system passwords .. all turn out negative.
And the ANSWER to your question ---> Grid Control >> Preferences >> Preferred Credentials >> Database Instance >> corresponding to my database name ; I enter my sysdba username / password AND the host username / password of my Linux box >> TEST >> which also turns out negative.
This entry is auto filled in since I "checked" the box "Save as Preferred Credential"; initially when I tried to start the DB using the STARTUP button.
By the way, my Win XP doesnt really have a password set under User accounts.
Any suggestions please ?

Oracle 10g Grid Control Installation On RedHat Advanced Server 3.0

I am planing to install Enterprise Manager 10g Grid Control Release 1 (v10.1.0.3)
on RedHat Advanced Server 3.0. The agent I am trying to download is showing version 10.1.0.4.1. I am not sure iof this agent is going to work with (v10.1.0.3). Pl. let me know if someone has performed this installation. Do I need to apply any patch on OEM and agent.
Thanks
Raj

Actually, entirely the other way around, unless you like seeing errors in your OMS.
OMS must be at at least the same patch level as the communicating agents.
10.1.0.3 agent against a 10.1.0.4 OMS = OK
10.1.0.4 agent against a 10.1.0.3 OMS = Bad mojo
Download the 10.1.0.4.1 patchset from Metalink and update your OMS, or stick with the 10.1.0.3 agent if you've no access to metalink.

Installing Enterprise Manager 10g Grid Control Using an Existing Database

I want to install Enterprise Manager 10g Grid Control 10.2.0.3 using an existing database. This database is RAC 10.2.0.2. and I use it as Infrastructure Metadata Repository.
I is said in Oracle documentation that SYSMAN schema has to be dropped, thus Database console repository has to be dropped. As far as I understand after Grid Control installation I will not be able to use Database console for my RAC 10.2.0.2 Infrastructure Metadata Repository database. I will be able to use only Grid Control for this database.
Am I right? Could you give me any advice about Installing Enterprise Manager 10g Grid Control Using an Existing Database?
Thank you.

Error - when creating a standby database with EM 10g Grid Control

Hi,
I am experiencing some problems when I want to create through the EM 10g Grid Control a standby database from a allready existing db. At step 2 when the files should be generated and copied to the other system, I am always getting the error that there isn't enough disk space on the other system. This can't be because there is at least 30GB free and the installer is asking for less than 1GB. I was searching the whole internet for a solution to this issue, but there was just nothing that could help me out with that point...
Has someone an idea at this point? Thanks for helping...
I am working on a Windows 2003 Server - Enterprise Edition for every system (Grid Control, Primary DB and Standby DB).
Best regards,
Patrick.

Check that filesystem space using GC under targets>hosts on which you are trying to create standby. Do you have any specific error message from GC ? If GC shows proper size under host filesystem section then there shuld be no such problem. Double chk ur locations too.

Trying to install OEM 10g Grid Control agent on Windows Server 2008 x64

Received the following when trying to install OEM 10.2.0.2 for Windows 32 bit. I believe Windows 64 bit version does not exist. I have installed this on 2003 x64 in the past.

10g Grid Control Installation/configuration on RAC

Hi Experts,
I am new to RAC and I need your help.
I need to configure 2 node RAC and install/configure Oracle 10g Grid control (High Availability) on HP-UX Itanium servers. Is there any good document or link?
Thank You all in advance
Bell

Hi Bell,
Here is the link for the 10gR5 Grid Control Installation Guide: http://download.oracle.com/docs/cd/B16240_01/doc/install.102/e10953/toc.htm
Considering the GC repository is a RAC database you will be performing the "+Using an Existing Database+" installation type.
I would highlight the below part of the documentation:
To view a list of certified Oracle Database, see Document ID 412431.1 on My Oracle Support (formerly Metalink).
If you want to use a RAC database, which is configured on a virtual host, as the existing database, then refer to Document ID 561441.1 on My Oracle Support (formerly Metalink).

Maintainance Calendar in 10g Grid Control

Hi All,
We are using Oracle 10g Grid Control and with Agent Version : 10.2.0.3.0 , OMS Version : 10.2.0.3.0 and Protocol Version : 10.2.0.2.0.
I heard that we can plan something like the maintainance calendar for generating reports to check any invalid objects,rebuilding indexex, generate statistics in Grid Control. I tried all the options and all the tabs but I could not find how to go on with that.
Can somebody help me on this.
Raj

How to setup DISK SPACE alert on OEM 10g Grid Control...

Gurus,
I am trying to setup DISK SPACE notification / alert thru OEM 10g Grid Control, but so far no luck.
Can someone help/guide me on how to achieve this?
Please advice.
Thanks & Regards,
Kartik

Those two links don't say anything about "DISK SPACE ALERT" I already know how to setup notification. I suppose you are talking about Filesystem Space Available (%)
If you need to setup an alert (Notification) then i suppose you need to setup an notification rule.
Yes, these notes do not have the key word "DISK SPACE ALERT" you are looking for, but if you go through the first note CLEARLY and COMPLETELY, you should find your answer.
And he has given an example for Filesystem space available in this note, which is what you are looking for.(I think so)
Say for Disk Space, you create a notification rule for target hosts and have metric "Filesystem Space Available (%)" defined in that rule.
If you aren't talking about notifications and just want to setup an filesystem space available metic, then follow this note:

Error while installing Oracle 10G Grid control in RHEL

I was installing Oracle 10G Grid control in RHEL. Got the following error. Any idea what this means and what is the remedy?
=======================================
Output generated from configuration assistant "Oracle Net Configuration Assistant":

I saw this once but I forgot how I solved it. I believe that I made a softlink to the libc.so.6 from another libc. Have a look on Metalink, becauses I've got the idea for my solution there.

I need to install Enterprise Manager 10g Grid Control Release 2 on Solaris 10 x86 platform.
I found out the following link where I can download the software:
http://www.oracle.com/technology/software/products/oem/index.html
Howerver it seems that there isn't any download for my platform. Does anybody know where can I find the software?
How can I configure EM Grid Control on that platform if I don't have the software. Does anybody know a manual installation and configuration method?
King regard and thank you

That means it is not yet available for 10.2, but it is for 10.1

Oracle Enterprise Manager 10g Grid Control Release 5

Hi All,
Has anyone here already using Oracle Enterprise Manager 10g Grid Control Release 5? Currently we are using Release 2 of Oracle Enterprise Manager as a package upon installation of Oracle 10g. Curious about Release 5 I want to try it out in our Dev Environment. But before making any changes. I would like to ask guidance from you.
Upon installation does it needs Operating System Patches, Packages etc.? Currently we are using AIX 5L Based Systems (64-Bit) and 10g for Database. Is this a complete installation or Just an upgrade?
