Oracle Data Guard Encryption

Oracle Database Tips by Donald Burleson


2008 Update - For a complete treatment of the topic of Oracle security on the web, see these books and resources:


Real Time Apply

If a delay is defined on a destination, with the DELAY attribute, and Real Time Apply is used, the delay is ignored.

When, for any reason, the apply service is unable to keep up, the apply service will automatically go to the archive log files as needed. It will also try to catch up and go back to reading the current standby redo log file as soon as possible.

Authentication and Encryption

Data Guard log transport services can now use authenticated network sessions to transfer redo data between the members of a Data Guard configuration. If the Oracle Advanced Security option is also installed, using encryption can increase security further and integrity checksums on network transmission of redo data.

Authentication is now required for all redo shipments. The remote_login_passwordfile parameter must be set to SHARED or EXCLUSIVE mode at all sites in the configuration. The password for SYS must be identical at all databases.

In order to enable encryption of the redo information, follow these requirements:

  • Install Oracle Advanced Security option at both the primary and standby database.

  • Set up the appropriate sqlnet.ora parameters as documented in the Oracle Advanced Security manual to allow Oracle Net to encrypt and integrity checksum the redo traffic shipped to the standby.

Oracle documentation should be consulted for information on setting up the encryption.

The above text is an excerpt from the book: Oracle Data Guard Handbook
