Oracle Solution for Error ora-16023

ORA-16023: system string destination cannot be the same as session string destination

What triggered the Error:

An attempt to change the first specified LOG_ARCHIVE_DEST_n (n = 1...10) parameter produced a destination that duplicates the session destination value of the second specified LOG_ARCHIVE_DEST_n parameter. This error can occur when setting a non-NULL value with the ALTER SYSTEM command. Or, this error can occur when setting a NULL value with ALTER SESSION command, because then the associated system destination value may appear as a duplicate.

What should we do to fix it:

Specify a different destination value for the first specified LOG_ARCHIVE_DEST_n parameter.
