Table 1-2 provides a list of the log files of most interest to you. How Do I Know If the Upgrade Is Successful? Of course, if you watch the DBUA to completion, then you will know the upgrade is successful (and that you can patiently outwait a very boring bit of screen output). The DBUA will provide you with the screen seen in Figure 1-3 which indicates success. After you click on OK, the DBUA will display the Upgrade Results page. html This is a summary of what the DBUA intends to upgrade. This HTML file is displayed by the DBUA before the upgrade begins.
In other cases, you are going to have to restore the database that failed to migrate yourself. In the DBUA interface, the last screen will give you an option to recover your database if there was an error on the DBUA. However, as in our earlier example, if the power went out and the DBUA session ended as a result, you no longer have that option. This is one reason I just prefer to do a manual backup/restore. DBUA does place all the files used to backup/restore your database into the logging directory.
Re-Run the Upgrade In the case of an error during a manual upgrade, you can often re-run the upgrade. Simply follow these steps: 1. Correct the problem. 2. Shutdown the database (shutdown immediate). 3. Restart the database with the startup upgrade command. 4. Re-start the upgrade process from step 9 in Table 1-4. After You Upgrade to Oracle Database 11g Once the upgrade script has completed the upgrade, you are almost done! Now we need to perform some post-upgrade steps to check the upgrade status and complete the process.
