After you have updated the database software, you can use the Database Manager GUI to make sure that the database instance recognizes the new software version.
1. Update the database software.
2.
Start the database
instance.
The first time the Database Manager is started after update of the database
software, it automatically adjusts the kernel parameters of the database
instance to this new version.
3. To update the system tables, choose Instance ® Configuration ® Upgrade System Tables.
The Database Manager creates a copy of the parameter file each time a parameter is changed.
UNIX:
<independent_data_path>/config/<database_name>.<running_number>
Microsoft Windows:
<independent_data_path>\config\<database_name>.<running_number>
<running_number>: Version of the copy, starting with 01
If parameter errors occur, the operation can be undone by restoring the original parameter file. To do this, use the Database Manager CLI program to copy the file <database_name>.<running_number> (copy of parameter file) back to <database_name> (active parameter file).
