I am doing some performance monitoring on an 8.1.7 DB on Windoze. I ran the following query;

SQL> select name,value
2 from v$sysstat
3 where name = 'redo log space requests';

NAME                                                                  VALUE
---------------------------------------------------------------- ----------
redo log space requests                                                  27

If the number of 'redo log space requests' is much over zero then I should increase the LOG_BUFFER size in my init.ora, at least that is what I get from RTFM. One question I have is that does the size of the LOG_BUFFER parameter have to be a multiple of the DB_BLOCK_SIZE parameter? I vaguely remember that it shuold be but have not found anything in TFM to verify this.

Thanks,

Dave
