Question: What
does the log_file_name_convert parameter do? Can you
show an example of using log_file_name_convert?
Answer: The log_file_name_convert
parameter changes location of redo log files of the
production database to a different location on the auxiliary
database.
This is used when cloning a database on the same server
where the file name locations will vary. See my notes
on
cloning diifferent directory structure. Also see
db_file_name_convert.
It converts the filename of a new log file on the
primary database to the filename of a log file on the
standby/clone database.
Syntax LOG_FILE_NAME_CONVERT =
'string1' , 'string2' , 'string3' , 'string4' , ...
Where:
string1 is the pattern of the primary database
filename
string2 is the pattern of the standby
database filename
string3 is the pattern of the
primary database filename
string4 is the pattern of
the standby database filename
You can use as many pairs of primary and standby
replacement strings as required.
You can use single or double quotation marks.
The
following are example settings that are acceptable:
log_file_name_convert='/u01/oradata/prod/','/ora1/oradata/aux/','/u02/oradata/prod/','/ora2/oradata/aux/'
