We have had file corruption before but never with Oracle. There is a product we use here that uses a priority database that does not do a two phase commit. When the disks fail over during the middle of a write it causes a huge issues. It took the vendor a week with a lot of our assistance to get one of the fab machines back up again. Very costly. They claim that their product is suitable for ServiceGuard as well. NOTE: they are now switching to Oracle as their database.
Just be real careful what you put under ServiceGuard. -----Original Message----- Travis Sent: Thursday, February 07, 2002 1:07 PM To: Multiple recipients of list ORACLE-L Could you explain the file corruption in a little more detail? I cannot imagine how failover would cause file corruption, much less how a properly configured running Oracle instance can get 'absolutely destroyed'. Isn't that the purpose of having Oracle over say a nonlogged, singlethreaded, cheapo db engine...? > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Thursday, February 07, 2002 9:00 AM > To: Multiple recipients of list ORACLE-L > Subject: Re:MC/Serviceguard vs Sun Clusters > > > Rama, > > We did the MC/ServiceGuard thing some years ago.
