Error in discoverer 9i desktop

Question

Hi all,
I am using discoverer 9i (9.0.2 to be specific) on windows 2000. I have created a few users and each user has his own EUL. coming to the problem, some users I have created get the error "unable to connect to database" after logging into discoverer desktop and when they are trying to create a new report. The usernames, password and conect string are correct as I am able to connect to sql with the same details.
Also, when they try to re-open a saved workbook, they receive a message "unabel to load eul item. Do you want to continue?"
can anybody help me with this problem.
thanks and regards,

Hmm
Are you sure the user has been a) granted access to the End User tool and b) has access to the business area(s) concerned?
Are you trying to access Desktop on the same machine as Administrator? If so, they should use the same registry settings. If not and the users only have a copy of Desktop is it possible that the registry could have become corrupt in the Discoverer area?
Is the user a local administrator on the machine? If not then Discoverer will be unable to edit the registry and will be unable to set the default EUL. Let's assume the answer is yes - the user is a local administrator.
When the user connects you say you see blank for the default EUL. This would explain why the user sees no business areas / items. Therefore, let's try assigning a manual default. To do this you will need the following information to hand:
1. Username as keyed into Discoverer - Eg. MSMITH
2. The EUL they are to connect to - E.g. EUL_US
3. The TNS entry they select in the database box - E.g. PROD
Here's a workflow:
1. From the Start button, select Start | Run
2. In the Run dialog box, type REGEDIT and click the OK button
3. Expand the folder called HKEY_CURRENT_USER
4. Navigate to the folder HKEY_CURRENT_USER
| Software | Oracle | Discoverer 9 | Database
5. Click on the folder called Database
6. In the right hand window you should see an ab entry called AEUL_MSMITH_PROD? The words MSMITH and PROD correspond to the username and TNS connection
7. If this entry does exist but the entry in the column called Data is incorrect or has nothing, proceed to step 10
8. If the entry AEUL_MSMITH_PROD does not exist, right-click in the column called Data and from the pop-up select New | String Value.
9 You will see an entry called New Value #1 - replace this with AEUL_MSMITH_PROD (replacing MSMITH with the real username and PROD with the TNS entry - both in uppercase) and press the Enter key on the keyboard.
10. Right-click on AEUL_MSMITH_PROD and from the pop-up select Modify.
11. In Value Data type the name of the EUL you want the user to connect to by default (in uppercase). E.g. EUL_US
12. Click the OK button
13. Close Regedit and launch Discoverer Desktop
Does this help?
