CONNECT -TIME FAILOVER ERROR IN ORACLE 10G ENTERPRISE MANAGER

Hi All,
Please can anyone explain why I am getting this error and how to fix it?
I was trying this exercise to create a backup LISTENER to support a connect-time failover in Enterprise manager.The steps were .1)I clicked the Listener's link on Database control page.2)Next I clicked the Net Services Administration link.3)I selected listeners from the Administer drop-down list and clicked Go.
I received the ERROR message that "Listener administration cannot be performed, as this Oracle Home
"/opt/oracle/DB10g" is not a server installation.
Is this normal?
What can I do to fix it?Please help!
Thanks

you are trying to start the listener on the machine that has enterprise manager installed.
Listener executable is available with oracle database software install( enterprise or otherwise).
You will have to pick the listener on a database software install box to configure it

Connecting to Oracle 10G Enterprise Manager console

Hi SDNers,
We've recently successfully upgraded Oracle from 9.2.0.7 to 10G (as part of a Solution Manager 4.0 upgrade) and I'm now interested in getting started with the new Oracle 10G Enterprise Manager (web-based console).
I'm at the point where I have EM up and running, but it is not connecting to our SAP database because it is trying to connect to port 1521, whilst the database uses 1527.
Does anyone know how to change the EM configuration so that it points to port 1527 and therefore connects to the SAP database?
Thanks in advance,
Arwel.

Yep!
Here's a copy of its contents:

Oracle 10g Enterprise Manager Console bug?

I think I have come across a bug in the Oracle 10g Enterprise Manager Console. If I go into my database, then into the schema, select your schema from the list, then tables. Now once your in your tables, find one that you know of and know fairly well, right click it, and select the show dependencies. A small window will open with just that table and its tablespace and user. Select user, database name, profile, then default. If you right click on the "default" and select "show dependencies" a blank blinking window will open and stay stuck in an infinite loop until you kill the application window. I think that this is a cumbersome tablespace issue. Any thoughts?

How to export Oracle 10g Enterprise Manager Grid jobs?

I need to save all current Oracle 10g Enterprise Manager Grid jobs before our migration. We are running Oracle 10.1.0.4 on Solaris 9. How can I save off the jobs to a file and re-import these after our migration into the new Grid server?

Download oracle 10G Enterprise Manager

I would like to download complete Oracle 10G Enterprise Manager. I downloaded one from oracle.com downloads and somehow it is not a complete. In that i do not have Console.
Where i can i download a complete 10G Enterprise Manager?

Which "console" are you referring to?
To download complete OEM is a non-existing concept. OEM is many, many products. You have Grid Control console, DB Control console, AS Control console.... and ta-da the java client console (old style) - as mentioned above install it from 10g Client software cd.

Oracle 10g Enterprise Manager Error

Hi,
I am getting below error when I open the Oracle-10G EM on GUI(Here my OS is Linux ES)
"java.lang.Exception: No Such Target", Any idea wt will be the cause?

Hi Leo,
I have the same issue.
1. I am using stand alone version.
2. "emctl start dbconsole" ran successfully and it said Database Control started.
3. I tried "localhost:5500/em", "MyComputerName:5500/em" and "IP Address:5500/em", all have the same result that after login and refresh, it shows "java.lang.Exception: No Such Target".
Connection to the database was fine. No other problem so far except for this error message.
Thanks for looking into it!

Oracle 10g enterprise manager create directory

Hi,
I am new to using Oracle 10g on Linux and struggle with creating a new directory using the Enterprise Manager "wizard".
I go to Database Instance > Directory Objects > Create Directory objects
and try it with \home\oracle , then test the file system it says directory not available.
pressing OK and continueing with my data dump does not work because I get the error "The directory does not exist"
I wonder why it has not been created?
moreover how do I delete the directory objects. I cant find a delete button using the enterprise manager browser ui ?

Hi EdStevens,
thanks for your reply.
I have heard this "read a book" a thousand times and gues what. I am
reading a book and this is exercise 9.2 and it tells me (as part
of the ultimate learning path) to use the enterprise manager
after I have created the directory with sqlplus.
I also tried the intuitiv DROP DIRECTORY in sqlplus as well but...
the directory does apparently not exist (altough I can see it clearly there in the list).That could be an ownership issue. Who does the directory belong to? who are you logged on as?

Hence I came to the conlusion to create a directory using the good old enterprise manager and it did not work too well either.
whatever I type in there I get file system does not exist. I guess I do something wrong with the PATH written into the textbox right?

Who are you connecting as when you log on to OEM? Try logging on with sysdba authority and you should see some more options available on the directory management page.

what I cant see is a delete button....

Oracle 10g Enterprise Manager

I recently upgraded one of my production databases to Oracle 10g from 9i. Everything was working perfectly. Now when I try to launch Enterprise manager I get "Server Error: Can't connect because of networking problems". I tried to stop and start the dbconsole but I'm getting an "OC4J Configuration Issue" error. The database fine.
Has anyone seen this before?
My server OS is RedHat Enterprise Linux 3.

Viewing Tables in Oracle 10g Enterprise Manager

Hello,
We are running Oracle 10g on a Linux Red Hat platform. We have started the dbconsole listeners to start using Enterprise Manager. The problem we are encountering is that tables that are in our schema are not showing up in Enterprise Manager. We have checked the tables using OEM and they are appearing there normally. The tables not showing were created from an object type. We are able to use DML, DDL on these tables using SQL, iSQLPlus. We appreciate any ideas. Thanks.

Please clarify how did you check the tables in 10g using EM dbconsole.
Please post some screen capture of you login using sqlplus and shown the table is there for example,
%sqlplus test/test1
