I'm having soo many issues with deploying my WOApp on an Xserve.
The Xserve has a gig of mem, 3 hd's (2 mirror'd raid, 1 data backup)
Mac OS X Server 10.2 (Jaguar) [out-of-the-box (no updates)]
WO5.1 [out-of-the-box (no updates)]
FrontBase (FrontBase Info Center says: v3.6.10, SQL92 says: DB VERSION =
3.5a, FB VERSION = 3.6.10)
Currently: 8 instances
Here are only SOME of my issues:
1. My app became unresponsive. Doing 'lsof -I' I found over 140 CLOSE_WAIT
states on the one bad instance. Someone said Adaptor re-build with code
change that closes channel. Ok, well, it didn't seem to make too much
difference, I still get lots of CLOSE_WAITs, perhaps not over 140, but still
lots.
2. I have a utility function that will fetch 15 thousand or so records and
create 15 thousand records. I run this on my dev machine (a G4 tower with
768meg of mem) in direct-connect mode and it runs through without stopping.
I run this same thing on the Xserve in direct-connect mode and it keeps
telling me I run out of memory. What gives? How do I check my VM usage?
Can I do it without altering my app? I found postings that suggest -mm and
-mx command-line args. I put these on the WOApp command-line and there's no
difference. I can't even tell if it's taking effect. I know I might be
programming in-efficiently, but shouldn't I be able to simply increase
memory size?
3. If I want (or need to) how can I update (software-update) the OS from
command-line?
4. How do I really check how much memory I have (I know have a gig, but
'top' gives me weird memory numbers)
5. Someone mentioned FrontBase deadlocks possibly causing the CLOSE_WAITs
when deploying multiple instances of a WOApp. I modified my connection
string accordingly and I still don't get performance results.
Well, I'm having a bad deployment experience. Firstly I wish I had direct
help from people who have deployed this particular configuration (all I get
is what seems like hearsay from someone who knows about WO5.1 and someone
else who knows about FrontBase and someone else who knows about Xserve, but
nobody with all pieces the same and no definitive expertise). All I know is
that my customer is a tiny company that can't afford the WO deployment
support from Apple iServices. And the customer now thinks WO5.1 was the
wrong choice because all he sees are JavaException pages with out-of-memory,
or application not available, or no instance available, or session expired
messages.
So, a big cry for help!

ps. Can't Apple make this software any easier?
