🖥️Environment Configuration Details:
Operating System: Oracle Linux 8.10 64 Bit
Oracle Single Instance DB : 19c
Oracle Single Instance DB : 19c
DB Name: AUTOUPG
Error Message: DBT-10328 Specified GDB Name (AUTOUPG) may have a potential conflict with an already existing database on the system
Description:
Error while installing Oracle 19c on Oracle Redhat Linux 8.10.
Troubleshooting:
Here, the error ocurred because already the same name database "AUTOUPG" was created in past and was not deleted properly.
Let's try to delete the conflict entry from Central and Local inventory logs.
Central or Global Inventory Location: /u01/app/oraInventory
Local Inventory Location: $ORACLE_HOME/inventory
If DBCA is still throwing the same error even after deleting the conflict entry from both Global and Local Inventory, it usually means some residual configuration or metadata of the database still exists in the Oracle environment. In this case, you need to check a few additional places.
💡 Observation:
Now I remembered that this database had previously been upgraded from Oracle Database 19c to Oracle 26ai Database, but it was not properly deleted from the 26ai ORACLE_HOME. Therefore, the database must be deleted from the 26ai ORACLE_HOME to resolve the issue.
Now, you can see that the conflicting AUTOUPG database entry has been successfully deleted from the Oracle 26ai ORACLE_HOME.
This confirms that the previously existing database configuration associated with AUTOUPG has been properly removed from the Oracle 26ai environment.
🔍 Result:
With the conflicting entry removed, the system will no longer detect the old AUTOUPG database configuration, and you can proceed with the database creation.
