Hi Mark,
Could you elaborate on WebLogic config you are using for RAC?
- Is it configured using WebLogic multi-datasources?
- Do you use WebLogic XA transactions? Does WebLogic datasource re-
tries transaction on reconnect?
- What are the patched you mentioned (perhaps, you have the reference
to the WebLogic support docs)?
Cheers,
Alex

We've been testing FSF with 10.2.0.2 and my co-DBA discovered a bug
that can cause a split-brain to occur. I don't remember the exact
circumstances, but the fix is in 10.2.0.4 which is driving us to
apply that patchset. Our FSF testing with 10.2.0.4 has been going
very well. If you use WebLogic, it will handle a failover but it
requires a patch depending on what version you use. I've been doing
new 10.2.0.4 builds with RAC and Data Guard with FSF for a new
customer. No issues so far.

Hi all
Anyone's using data guard fast-start failover ?
What are the experiences ?
What about split brain?
Does it interfere heavily with normal database activities?
Any other comments?
Thank you in advance,
