Hi,

Can we change log_buffer parameter online e.g. when all users are working.. ???

What is relation between redo buffer in sga and log_buffer parameter ?


SQL> show sga

Total System Global Area 3758096384 bytes
Fixed Size 1983152 bytes
Variable Size 553655632 bytes
Database Buffers 3187671040 bytes
Redo Buffers 14786560 bytes
SQL>
SQL> show parameter log_buffer

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_buffer integer 14338048
SQL>
SQL>

If the log_buffer parameter is 14 MB then why redo buffer is no as same size e.g.
14 MB
