Updating encrypted data using MigrateEncryptedInfo (server offline)
You can change the merchant key and update the encrypted data using the command line tool, MigrateEncryptedInfo. This utility supports two ways of specifying the values of the merchant keys. One is to provide the actual values of the old and new merchant keys as command line arguments. The other is to retrieve the values through the Key Locator Framework.
Note:
- If you want to consider an option with a minimal downtime, see Updating encrypted data using MigrateEncryptedInfo (server online).
- You can now run the MigrateEncryptedInfo utility in a development environment as long as the server is offline.

space to autoextend with maxsize unlimited. From an SQLPlus prompt,
enter the following command:
