Kevin,
I would not use replication for U2 for 6x. I was given the mandate to use
then IBM replication at a company I used to work for, and it didn't work.
It wasn't on problem, but a whole hosts of problem. I set up two test boxes
four different times and tested it. The 4th time I had 30 people from then
IT staff (I was part of the staff then) hammer on it. Then we went live.
It worked for 4 days then crashed the whole system. Then it worked for a
few hours. Then, it kept crashing (hanging the servers). We had to pull it
out. We were on Unidata, but it's the same code base.
I can only say that if you want to go ahead with it, find someone who's
using it successfully, and find out what environment they're in, version,
ect. It's based on Unix and has different issues on different O/Ss. But,
personally, I'd try RFS first, or write your own. That's what we ended up
doing. And it worked. We used triggers and hammered the system 24/7.
There were some issues, but we worked them all out, and we're able to
process millions of transactions per day. What we ended up doing is finding
all the weak spots in Unidata and avoiding them. The biggest weak spot was
locks. The system couldn't hanldle the million+ locks per day. I went to
double buffering, avoiding locks (an old GUI technique!). Also, I had to
convert types of records to hex, and the UD hex conversion is slow. It's
amazing what works in UD and scales, and what doesn't. To write one's own
takes time and is expensive. I think that using mirrored drives is
better!!! RFS???

Subject: [U2] Unidata 6.1 Replication
Is replication solid and functional in Unidata 6,1? Anyone using it with
roaring success?
