One thing, I haven't done the bounce. I thought that this was a dynamic parameter. I will get permission to bounce this db in a sec. Btw, Allen, it is a posting from you in 2006 that I was following. I see that you had the same problem the. I guess that that makes you the expert on the topic. -Claudia -----Original Message----- From: Allen, Brandon [mailto:Brandon.Allen@xxxxxxxxxxx] Sent: Monday, September 29, 2008 4:47 PM To: Claudia Zeiler; oracle-l@xxxxxxxxxxxxx Subject: RE: db_file_multiblock_read_count How do you know you're "being ignored"? Just because it shows a value of 128 doesn't mean your "reset" isn't working - maybe 128 is the value that Oracle is coming up with? Try this: select isdefault from v$parameter where name = 'db_file_multiblock_read_count'; If it's not the default, you might want to try this: alter system reset db_file_multiblock_read_count scope=spfile sid = '*'; Then bounce your instance and check again.
