LOG_FILE_NAME_CONVERT does not work for SRL(Standby redo log) when RMAN Duplicate is performed with Standby as target for Cascade Standby Database creation

(Doc ID 2399265.1)

Last updated on MAY 28, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.2 and later
Information in this document applies to any platform.

Symptoms

When RMAN duplicate is run from the standby as target to create a cascade standby RMAN creates datafiles for the new cascade standby as per the db_file_name_convert but is not able to convert the values for log files as per the parameter log_file_name_convert for SRL (Standby redo log file), though it works for ORL.



If the cascade standby is on the same host then it overwrites the log files of the target standby database.

Following is the error RMAN logs at the end of duplicate:

When duplicated from the Primary database as target it worked fine

In this scenario the standby and the cascade standby are in the same host.

Changes

 No changes made. Tried creation of cascade standby from the standby database as target.
