Create Configuration File for AutoUpgrade

To use AutoUpgrade to complete the upgrade, you first create a configuration file with AutoUpgrade from the new release Oracle home.

In the following example, the AutoUpgrade utility is run using the parameter sample_config_file. This parameter generates a configuration file in the home of the user running AutoUpgrade that you can edit to provide environment paths and settings and upgrade preferences for the upgrade. To generate the configuration file (config), you run AutoUpgrade from the new release Oracle Database home using the sample_config_file parameter, and specify an output file name.

In this example, user oracle navigates to the location of an earlier release Oracle home, which in this case is Oracle Database 12c Release 2 (12.2):

cd /u01/app/oracle/product/12.2/

Next, the Oracle user starts AutoUpgrade from the Oracle Database 19c Oracle home, and creates a configuration file in its user home directory, /home/oracle:

java -jar /u01/app/oracle/product/19/rdbms/admin/autoupgrade.jar -create_sample_file config
Created sample configuration file /home/oracle/sample_config.cfg

After you create the configuration file, open it up in your preferred text editor, and modify parameter settings as needed for your environment.

cd /
vi sample_config.cfg
