Troubleshooting the ORA-65096 Error
If you encounter the ORA-65096 error, follow these steps to troubleshoot the issue:
Step 1: Check the Name
The first step is to check the name you are trying to use. Make sure that the name is not already in use by another user or role. Check the Oracle documentation to ensure that the name you are trying to use is a valid identifier.
Step 2: Check for Reserved Words
If the name you are trying to use is a reserved word, you will need to choose a different name. You can find a list of reserved words in the Oracle documentation.
Step 3: Check for Special Characters
Make sure that the name you are trying to use does not contain any special characters. Only letters, numbers, and underscores are allowed in user and role names.
Step 4: Check the Character Set
Make sure that the character set you are using is supported by Oracle Database. If you are using a character set that is not supported, you may encounter the ORA-65096 error.
Step 5: Check the Quoting
If you are using quotes to enclose the user or role name, make sure that you are using the correct type of quotes. Oracle Database supports both single and double quotes, but you must use the same type of quotes to open and close the name.
