Selecting a Database Instance

From the Available Databases table, select the database that you want to upgrade.

Usage Tips

When you use this page to select a database to upgrade, consider the following notes:

• You can select only one database at a time.

• If you are running Database Upgrade Assistant (DBUA) from a user account that does not have SYSDBA privileges, then you must enter the username and password credentials to enable SYSDBA privileges for the selected database.

• After you click Next, DBUA displays a dialog as it gathers critical information about your database. This may take a few minutes, depending upon the amount of data that is in the database, as well as the current load on the database.

Troubleshooting Tips on Microsoft Windows Systems

If you are using Windows and you do not see the database you want to upgrade, then make sure that the database service is present in the Services control panel:

1. From the Windows Start menu, select Settings > Control Panel > Services.

   OR

   From the Windows 2000 or Windows XP Start menu, select Control Panel > Administrative Tools > Computer Management > Services and Applications > Services.

2. For single instance databases, verify that the service for the database is present in the Services control panel.

   The service for a single instance database is of the form OracleService<DBNAME>. For example, the service for the single instance starter database ORCL is called OracleServiceORCL.

3. For Oracle Real Application Clusters (Oracle RAC) databases, verify that the services for the database instances are present in the Services control panel on the corresponding nodes of the database instances.

   A service for an Oracle RAC database instance is of the form OracleService<INSTANCENAME>. For example, the service for an instance of the Oracle RAC starter database ORCL1 is called OracleServiceORCL1.

Troubleshooting Tips on UNIX and Linux Systems

If you are using a UNIX system and you do not see the database that you want, then make sure that an entry with the database name exists in the /var/opt/oracle/oratab file.

If you are using a Linux system, then ensure that the database entry exists in the /etc/oratab file.

For an Oracle RAC database upgrade, ensure that an entry with the database name exists in the /var/opt/oracle/oratab file on all the nodes of the cluster databases.
