How do I reformat v$session.osuser? - weblogic

Question

I am trying to set up an Oracle WebLogic Datasource for my job. But every time I try to connect to the database, I get this error:
Connection test failed.
Message icon - Error Connection property: format error: Property is 'v$session.osuser' and value is 'Yann (Intern)'
I tried changing my username to "YannIntern" to remove the special characters, but the error is still the same and it also happens when I try to use Oracle SQL Developer. How can I stop the format error?

Answer 1

Java reads this from the user.name property which defaults from the os username. However, this can be overriden by setting -Duser.name=Yann
Here's an example in sqlcl
SQL> select sys_context('userenv', 'os_user') from dual;
SYS_CONTEXT('USERENV','OS_USER')
------------------------------------
klrice
<<< a short command to set java properties >>>
<<< which is the same as a -D property >>>
SQL> set property user.name kris
Setting user.name to kris (klrice)
SQL> #connect-klrice
Connected.
SQL> select sys_context('userenv', 'os_user') from dual;
SYS_CONTEXT('USERENV','OS_USER')
----------------------------------
kris
SQL>

Answer 2

Same happened to me, I have parenthesis in my computer's name. I spent a lot of time researching but finally, I have the solution (I created an account just to answer this haha). To solve this you have to:
-Go to the folder location where you installed SQL Developer.
-Then go to: \ide\bin\ide.conf
-At the end add the following line:
# Custom VM Option
AddVMOption -Duser.name=<YourUsername>
-Save the file, and restart SQL Developer, you will be able to connect and avoid that error message.
