Hi Craig; We have written our own session app in perl... It uses /tmp/SUNWut to get the stationid and card. It then queries a mysql db to see what options to pass to uttsc. It sets up 2 utactions, and then runs uttsc. It does not use utwho or utsession.
I'm not especially comfortable changing utprodinfo based on the comments on the website that there is a risk things won't work. Any thoughts on this? As to java... We're using jdk 1.6.20. I believe it already has a larger default heap size than 1.4. We're not trying to solve a specific problem, but implement best practice proactively. That said, we had hellish problems in utauthd in linux (rhel5). We'd tuned the java params and worker threads per docs, and while I don't believe that caused the problems, I'm all too aware of how bad my life gets when 500 users stop being able to login and hotdesktop (which each user usually does once every 15 minutes) if utauthd stops working, and don't want to do anything that would even remotely risk that.

I really hate the package checks we do. I need to file an RFE to stop that. While I understand that we are being cautious, the kiosk session couldn't even start if the packages weren't installed. Maybe check on system bring up, but not for every single user. Java is another one we need to issue some updated guidance on...In 1.5+ I believe we should be giving it the client option if we are not already. The other question since you mention performance and stability, what is currently happening? Is it unstable? Slow? Devin Nate wrote: > Thanks Craig...
