log_file_name_convert tips

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/'
