Logon problem with oracle management server

I have problem with Oracle Management Server when I connect to the OMS message comes
The exception (java.lang.NullPointerException) occurred.
if any body have any idea pls tell us

Hi,
Oracle has changed the Enterprise Manager from version 1.5 to 2.0 .
With the new Oracle8i dataase server another service has been added.
If you want to user the OEM you have to install The Managment Server.
The Managment server has its own user and privileges and is recommended when using OEM.

Has anyone had the similar problem?
There is another problem with the MS2. I created boot.properties and seems it does not affect because the start still asks for the username and the password.
I have done the same with MS1 without the problem.

Hi Jose,
To Disable SSL communication for NodeManager do the following:
Step1). Open the *"nodeManager.properties"* file from *<WL_HOME>\common\nodemenager* (Example Location : C:\bea103\wlserver_10.3\common\nodemanager ) directory and change the value of SecureListener property to false:
SecureListener=false
Step2). Login to AdminConsole and then
AdminConsoleHome--->Machines --><Your_MachineName> (Click here)--->NodeManager (Tab)---> Select the type as "Plain" from the combo box (by default it will be SSL)
Step3). Restart the NodeManager ....better if you follow Step4) as well...
Step4). Please Enroll your NodeManager as described in the Step8) of the following Link: http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/

Problem with oracle report server

Dear All
I have deployed Oracle application server 10g forms & report services on win 2003 server.
but problem is that after some interval report is getting hanged and not opening on web browser,
If i restart the report server then it will come very fast.
As i am new to this field Can anybody tell me how can i investigate the problem of report server.
Your reply would be greatly appreciated.
Thanks

you can modify the report engine in EM console, you can put one or more JVM for this as well that it have expiration day, this will be helpful, because you can put an iddle time, so when the engine get it, it will be restarted, as well max of process again will be restarted.
Greetings.

Logon problem with Oracle AS Adapter for SAP R/3

Dear All
I am getting below error, when trying to test the SAP Adapter. As seems from the message, its a credential problem, but the same user id/password works fine when using SAP Logon Gui Front-end client.
Any help/pointers highly appreciated.

Further inputs/thoughts,
1. This must be a very basic, can it be because my user id/password does not have sufficient privilege?
2. I am using adapters_10131_win32.zip downloaded from Oracle, installed only SAP Adapter and then trying to connect using Adapter Application Explorer.
Regards.

Thank you veyr much Manoj for your reply. I just tried it now buit no fruits.
I wonder if it can really be due to privileges given to my account, which allows to connect thru SAP Front-end but does not allow to connect by any other means. I can not think of any other possible reason.

Deployment Manager Error with Oracle Weblogic Server 10.3.1

I have installed Identity Manager 9.1.0.2 (patch upgraded from 9.1.0.1) on OEL 5.3 64bit and Weblogic 10.3.1
Database:Oracle 11gR2 (remote machine).
**I am aware that IM 9.1.0.2 is not certified on Weblogic 10.3.1 (it is only certified on 10.3),
The installation was successful and OIManager is up and running. Able to create Users, Resources etc. as well.
As part of configuring OIM Connectors tried to Import .xml file using Import option from Deployment Management section as below and the following error was displayed.
"Either your session timed out or you are trying to access a page without logging in".
Did all workarounds like enabling java, changing browsers, restarting machine etc as per the below discussion but in vain.
Deployment Manager Error with Oracle Weblogic Server
Can any one suggest any workaround or solution for this problem.
Or atleast can any one confirm there is no Identity manager available on this date which is compatible with 10.3.1? and cannot be continued further.
Thanks in Advance
Sudheer
Edited by: SudheerPrabhala on Oct 20, 2009 1:26 AM

You are facing this issue because you're using a non certified combination.
Other folks who tried to use OIM in 10.3.1 ended up in the same problem you're facing.

Problem starting the Oracle Management Server service

Hi
I have configured the Oracle Management Server (since I need to use the Jobs functionality) in an Oracle 9i home installed in my desktop. Then I have tried to put the service to work; it always starts and stops at once; the message also states that some services are automatically shutted down when they are not in use...
Also, I noticed that I cannot use the typical option when creating the repository for OMS because it does not accept the domain my computer is in (dgsaude.min-saude.pt) since it seems to be an invalid domain name...
I am a little under pressure here...Please help

Thank you very much; I will take a look at documentation; anyway, just a question I am in doubt about..the tasks I need to automate have to do with deleting the contents of some local tables, then run some SqlPlus queries to fill those tables again (I run them locally by using a database link to another database); final tables will be connected to an www site and refreshed. As I have understood, I can do this using DBMS_JOBS (for which, I think, I would need to learn some PL/SQL...) or configure the OMS to do it (which, as you said, can be a bit of a pickle in the start...). Given the situation, which one of these tools would you advise me to use?
Thank You
Andre

I have problem with Adobe ColdFusion Server Manager.

I have a problem with Adobe ColdFusion Server Manager when you log on and connect to the server. An advantage of the settings do not load.

When I see others screen cuts of CF Server Manager here:
http://www.coldfusionjedi.com/index.cfm/2009/10/21/Quick-example-of-Diff-within-the-ColdFu sion-Server-Manager
http://forta.com/blog/index.cfm/2009/7/6/Simplified-ColdFusion-Server-Management
the Errors View button display’s the yellow ! sign. Without a better guide I just thought that is a normal button icon until I noticed Charlie comment earlier in the thread and I thought hold up that is not normal.
As it is when I press Errors View I get “no error” which might be because there is none or just simply not giving meaningful details as per some other CF Server Manager limitations previously noticed in other threads on forum here.
I just hope some of that helps the original post to do with the display of the settings on left side. Maybe a better look at the error might help? Does anything get logged in CFadmin UI > Debugging & Logging > Log Files that relates to issue?
Regards, Carl.

Error while starting Oracle Management server service

Hi all,
We are about to administer our database using Oracle Enterprise manager. For that we have configured OEM in a Test PC and tried to connect our database.
First i have logged in to OEM Console with Sysman login id using the default password "oem_temp" and it prompts me to change the password, also i have changed the password as "xxxxx" and i have come out of OEM console and tried to relogin using the changed password.
i got the message as invalid login or password or
check for the availablity of Management server service"
i found that the service Oracle Management server which was previously running is not running now and i tried to restart that manually.
On doing that i got a message as
"Error 1053: The service did not respond to the start or control request in a timely fashion"
Would any one of u help me to solve this problem.
Thanks in advance..

Hi-- could you please describe your administrative domain?
I need to know the operating systems on each of the
clients and the OSB admin server. Also, does 'obtool' CLI
tool work? Do any of the machines act as an apache webserver
for another application? Is there any other backup service
running on any of the machines?
thanks,
Judy
I noticed that when re-installing the OSB without the
Administrative Server (only Media Server and Client)
I got no errors at all (but still cannot connect from
another Administratice Server to my machine)

What's the name of my Oracle Management Server?

I have just completed a new installation of Oracle 9i DB Ver 9.01 along with the related Oracle Management Server. I can log into the Oracle Enterprise Manager OK, but I can't log in to the Oracle Management Server.
The problem is that the login requires me to provide the name of the Management Server, and I don't recall ever being asked to assign a name to the Management Server during the installation process.
The names relevant to my database installation are:
Host server name: Tower100
Database name: TOWER
Service_Name: Tower.LinFamily
Repository DB Name: TowerRep
Repository SID: TowerRep
I have tried all these names, and they don't work. I have tried logging using the user names 'system' and 'RepAdmin' (the user name I assigned for the repository), and they don't work.
I have looked through the installation documentation and I can't find anything on this subject.
I would appreciate any help on this problem. Thanks.
Tony Lin

David,
Thanks for your response.
Yes, I am running Win2000 Server. I checked Component Services and verified that both Management Server and Agent are processes set in automatic mode and started.
David, my problem is that logging in to Management Server requires me to enter the Name of the Management Server. What is the "Name" of my Management Server? I don't understand what this means as I do not recall ever being asked to name my Management Server when I installed it.
The names relevant to my database installation are:
Host server name: Tower100
Database name: TOWER
Service_Name: Tower.LinFamily
Repository DB Name: TowerRep
Repository SID: TowerRep
Are any of these the "Name" of my Management Server?
I have tried all these names, and they don't seem to work.
Also, when you say the default account name, do you mean the account "SERVICE" with the default password?
Tony Lin
Tony,
If you installed on Windows then you will want to make sure that the Management Server and Intelligent Agent services are started in the Services Control Panel first.
Otherwise if you are using a UNIX server, you may need to start the mangement server manually. Here is a script I use to automate the startup process on Solaris:
http://www.dotcomsolutionsinc.net/products/installgen/sol_901_32bit_files/installgen_sol901_12_.html
From the Enterprise Manager Console login window you can click on the icon to the right of the Management Server field, click on the Add button, then enter the hostname of the management server to add it.
If the Management server is running, then you should be able to log in using the default account the first time, then create your administrator accounts.

Oracle Management Server Service not created

Hello,
I created a Management Server Repository using OEMCA and an existing SID. According to the details displayed at the end of the wizard I assume that the process was finished successfully:
(NT-Service OracleOraHome81 ManagementServer is started...
Disconnect from oms@instancename....
Returning to connection system@instancename...
Process finished.
Yet the Oracle Management Server Service can not be found in SERVICES in the control panel...and therefore can't be started manually.
I have OS-Administrator Privileges.
I use Oracle 8.1.7 on WinNT.
Any help would be greatly appreciated.
Thanx

Hello,
I too am an Ashford University student, and I have received the same error. However, I have found a couple workarounds that allow me to do pretty much everything except view my degree progress (for that I use Chrome on my iMac).
****CAUTION: THE FOLLOWING PROCEDURE COULD RESULT IN LOSS OF DATA****
First, back up your iPad in iTunes (if you do not know how to do this, then do not proceed until you do). Second, quit Safari (double-tap the home button so that the multi-task bar appears at the bottom of the screen, then swipe until you see Safari, then press and hold the Safari icon until the 'X' appears, finally press the 'X' to quit the App) Third, make sure Safari is configured as follows:
Settings > Safari >
Java Script "ENABLED"
Block Popups "OFF"
Accept Cookies "ALWAYS"
Reset Safari:
Settings > Safari >
Clear History
Clear Cookies
Clear Cache
Restart your iPad by holding the Home and Sleep buttons until the Apple Logo appears (immediately let go of both buttons or else you will put your iPad into recovery mode). Accessing the Ashford Student portal should now work.
