Server Perf Increase

2004-04-21 Thread Kumar
hello list,

  i have high performance dell server. i want to
increase Read_Buffer_Size server variable to 5 MB.

 i have found docs on this in mysql site. like this

mysqld_safe --key_buffer_size=64M --table_cache=256 \
   --sort_buffer_size=4M --read_buffer_size=1M


  where i type that command i am getting status
message as Mysqld is already running.

   how can i change those variables to take effect
permanently.

thanks,
Kumar

You can restart MySQL server with new value of read_buffer_size.
If version of MySQL server = 4.0.3 you can set variable at runtime using SET 
statement:
