SYSSTAT statistics for buffer writes?
Date: Wed, 25 Feb 2009 10:44:09 +0100
I need to create a statistics overview for reads vs. writes on a 10gR2 database. Desire is, to compare "session logical reads" ('The sum of "db block gets" plus "consistent gets". This includes logical reads of database blocks from either the buffer cache or process private memory.' by 10g documentation) with its counterpart in writing. I don't want to gather information about phyiscal IO.
My first attempt was to use "db block changes", but obviously it misses blocks created by INSERT operations (' <...> this statistic counts the total number of changes that were part of an update or delete operation that were made to all blocks in the SGA. <...> ').
Is there any idea how I can cover ALL blocks changed AND created?
Thanks a lot in advance and best regards,
Mit freundlichem Gruß
