Code:
The syntax of the command is a bit tricky. For example: ln -s oldfile newfile links the
previously existing oldfile to the newly created link, newfile.

in your case there are no newfile name you must put it.

radsqlrelay

RADSQLRELAY(8)						     FreeRADIUS helper program						    RADSQLRELAY(8)

NAME

       radsqlrelay - relay SQL queries to a central database server

SYNOPSIS

       radsqlrelay [-?]  [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path

DESCRIPTION

       radsqlrelay  tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) data-
       base, even if the database has extended downtime.

       The SQL logfile is created by the rlm_sql_log module. The module must be configured in the radiusd server before you can use radsqlrelay.

OPTIONS

       -?     Print usage help information.

       -d sql_driver
	      Driver to use: mysql, pg, oracle.

       -b database
	      Name of the database to use.

       -f file
	      Read password from file, instead of command line.

       -h host
	      Connect to host.

       -u user
	      User for login.

       -P port
	      Port number to use for connection.

       -p password
	      Password to use when connecting to server.

       -1     One-shot mode: push the file to database and exit.

       -x     Turn on debugging.

       file_path
	      The pathname of the SQL logfile to use.

NOTES

   Oracle driver
       The command "radsqlrelay -d oracle -b db.domain.tld sql-relay" reads the database description stored in $TNS_ADMIN/tnsnames.ora:

       db.domain.tld =
	 (DESCRIPTION =
	   (ADDRESS_LIST =
	     (ADDRESS = (PROTOCOL = TCP)(HOST = db.domain.tld)(PORT = 1521))
	   )
	   (CONNECT_DATA =
	     (SERVICE_NAME = <DB SID>)
	   )
	 )
