Oracle Enterprise Manager Database Control is not working properly
Hello!
I have a problem with Oracle Enterprise Manager Database Control, the web console. When I open the browser, instead of showing the login window, it shows the window where three arrows, the database instance, the listener, and the conection, that are red and down.
However they are working correctly, the database is up and working, but the EM doesn't show anything else.
Is there a way to make it work again?
Thanks!
The Enterprise Manager has lost sync with the database.
The only way I know to do this remotely is to tell the OEM to shut down and/or bring up the database - twice. It'll try and fail and perhaps eventually reset it's pointers.
I'd really like Oracle to create a 're-sync to actual state' URL ... there must be an easy way, such as flushing the collected metrics or something.

Oracle Enterprise Manager Database Control VS Grid Control
What is difference of Oracle Enterprise Manager Database Control and Oracle Enterprise Manager Grid Control?
How I can install it manually?
ThanksWhat is difference of Oracle Enterprise Manager Database Control and Oracle Enterprise Manager Grid Control?
How I can install it manually?Dbcontrol is for single database as Grid control is for multiple databases.Dbcontrol has limited features than Grid control that goes beyond database administration to monitor other targets that include Operating system and application servers, web application, High availability (data guard) configurations. Database control comes with oracle server license but Grid control is a separate product it required separate license. If you want to use basic features then you can turn off the licensed packs in Grid control and use free product.
Install Grid Control as doc:http://download.oracle.com/docs/cd/B16240_01/doc/em.102/e10953/installing_em.htm -
Oracle Enterprise Manager Database Control
Please help me.
Here's oracle installing step:
1. Install Oracle 11g software with "Advance" option. I just install software without creating a Data base at this time.
2. Create a Data base with DBCA
I couldn't see the Oracle Enterprise Manager Database Control at "Services " window while
"Chapter 3: Getting Started with Oracle Enterprise Manager" says that:
This chapter introduces you to Oracle Enterprise Manager Database Control. The Oracle Universal Installer installs Oracle Enterprise Manager Database Control when you install the Oracle software. Enterprise Manager Database Control provides a Web-based interface that you can use to manage your Oracle instance and database.
Thank in advance!Hi,
You didn’t create a Database that’s why you don’t have Oracle Enterprise Manager Database Control.
Create Database with DBCA and you will get an option “Configure database with Enterprise manager” (step 5).
At the end of DB creation you will get a link for Oracle Enterprise Manager Database Control.
Browse the link to open EM Database control.
If you choose to create DB with Oracle installation then you will get Oracle Enterprise Manager Database Control.

Enterprise Manager Grid Control - SSH not working on Windows
Hi,
We tried the below steps to install EM Grid control on our Windows servers.
• Oracle Application Grid Control with Oracle Management Agent has been installed successfully on Server1.
• As part of prerequisites for Agent installation using Agent Deployment Wizard, we have installed Cygwin in both the boxes – SOA box (Server2) and Grid control box (Server1) for SSH communication. However, the agent installation failed and the service in SOA box failed to start. We tried re-installation of Cygwin but unable to bring up Cygwin service.
• We have installed SOA suite in another box (Server3) and then installed Cygwin. Cygwin installation was successful and all previous issues were resolved.
However, SSH communication is getting failed because of the error "User Authentication failed on remote nodes:Server3. Either the provided username and password is incorrect or Password Authentication is disabled for the sshd daemon on the remote nodes. To enable Password Authentication set the property PasswordAuthentication to "yes" in the SSHD Configuration File (sshd_config) on the remote nodes".
We are able to achieve SSH communication when we manually try it through Cygwin Bash Shell.
Any pointers in resolving this would be highly appreciated.
regards,
Satyajith
Edited by: 817555 on Dec 12, 2010 10:11 PMI couldn't get to work either so I left the ssh configuration out and went on with 'silent' installation which worked like a charm and oem discovered it right away. Be sure change the parameters according to your environment in 'additional_agent.rsp' file and use that to run the silent installation. You may have to add one additional parameter manually about agent home location, look in the documentation for the exact parameter name. Hope this helps, Viral.

Hello everybody i use Oracle Database EE 11.2.0.4 with DG.
In those cases i need to get Enterprise Manager Database Control running against DB with no RAC and no DG i perform the following steps:
I Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects:
DECLARE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
ELSE
EXECUTE IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
END IF;
END LOOP;
END;
DROP USER mgmt_view CASCADE;
DROP ROLE mgmt_user;
DROP USER sysman CASCADE;
After that i run
emca -config dbcontrol db -repos recreate
But what should i do in cases i have 2 servers working (primary and standby) under DG rules?Hi ,
It is not possible to monitor/administer a Logical or Physical Standby database, i.e Data Guard, using Enterprise Manager Database Control. This is primarily due to the fact that Database Control is designed to monitor 1 database and a Data Guard environment, by definition, includes more than 1 database.
If you attempt to run emca against a standby Database, you will get an error like (i.e. ORA-01219: database not open).
Database Control, can, of course, be used to monitor the current Primary database (with no ability to administer or monitor Data Guard related functionality). In such a case, when failover occurs Database Control must be reconfigured to run on the new Primary database using the commands detailed in Note 278100.1 How To Drop, Create And Recreate DB Control In A 10g Database, section C. Recreate/ReConfig DB Control, Option 2. Recreate the DB Control Configuration Files and Repository.
Enterprise Manager Grid Control or Cloud Control provides the functionality for viewing, monitoring, and administering primary and standby databases in a Data Guard configuration.
Reference: Is it Possible to Configure Database Control for a Logical or Physical Standby Database? (Doc ID 315116.1)
You can use EM 12c cloud control to monitor and manager Standby DB effectively

Backup problems from Enterprise Manager Database control
I'm having a problem with performing backups from EM DB Control on two of my Oracle 10g 10.2.0.4 systems. When I configure and submit any backup job from EM (either online or offline), the following happens:
- When the job is due to run a Pre backup task has status of 'Scheduled'
- Prebackup task completes and status changes to 'Succeeded'
- Backup task appears with status of 'Scheduled' and value of started time within the next minute
- Status of backup task never changes from 'Scheduled', and the started time keeps updating to the current time
- This goes on indefinitely until I abort the job
At the moment I have scheduled tasks configured to run an RMAN job every night, but I need to get this working through Enterprise Manager Database control. Please help!
Something else which has happended on one of these systems is that after applying some Microsoft Critical updates the database control service would not start. The only way I could find to resolve this was to recreate the Enterprise Manager repository. Could there be a link here at all?
Cheers,
StrakI think Rodney may have the cause, because the database has been copied. I have looked in every property file I can think of, and then all the rest anyway, and there is no reference to the old host name. And I have ralready e-installed EM using emca -config -dbcontrol db. And I'm definately on the correct port.
So it must be held internally in the database. I've seen partial instructions on deleting the EM repository in the database & java files, does anyone have a full set I can use ? Once that is done, does emca reinstall everything ?
Many thanks, Duncan -

How do I create a new emkey for Enterprise Manager Database Control?
I do have a copy of my old key but it is no longer good because I reinstalled the repository with these commands:
emca -repos drop ...
emca -repos create ...
Oh, and where is emctl "documented".
I poked around in some book-index links and with the search engine.
I could not find anything.

Oracle 9.10 Database Configuration Assistant not working
I have installed Oracle 9i Enterprise Edition on Windows XP, Pentium 4 and everything installed successfully but after installation, when I click on Database Configuration Assistant, nothing happened, no error displayed, mouse flashed for a while as loading something then came normal.
