PowerExchange Express CDC for Oracle Ability to Read Copies of Archived Redo Logs

PowerExchange Express CDC for Oracle Ability to Read Copies of Archived Redo Logs

Effective in PowerExchange 10.1, you can configure PowerExchange Express CDC for Oracle to read change records from archived redo logs that have been copied to an alternate file system.
Use this feature in the following situations:
  • You do not have the authority to access the Oracle archived redo logs directly.
  • The archived redo logs are written to ASM, but you do not have access to ASM.
  • An aggressive archived log retention policy is in effect on the database server, which causes the archived logs to not be retained long enough.
To configure PowerExchange Express CDC to read copies of archived redo logs, set the MODE parameter to ARCHIVECOPY in the READER statement of the PowerExchange Express CDC for Oracle configuration file, pwxorad.cfg. Then specify the name of the base directory that contains the copies of the archived redo logs in the new DIR parameter. Optionally, use the new FILE parameter to filter the copies of the archived logs that reside under the base directory.
For more information, see the "Express CDC for Oracle" chapter in the
PowerExchange CDC Guide for Linux, UNIX, and Windows
