Hi SunRay Users; For the Oracle folks - about a year ago, we deployed SRSS on Linux and it completely fell over. RHEL 5 deployment, fully supported everything - due to our SLA's we don't do anything but best practice. Based on the threads about GDM, I'm suspicious the massive failures we saw are related to this.
Since then we moved to Solaris 10, which has been rock solid. We're gun-shy of GDM, Linux, and Solaris 11, based on those massive failures and large costs to our organization. The consequence to the failure then was that we had to credit our customers $50,000, real cash, due to SLA misses; it was not a fun time at all - an average of 20 hours downtime per week for 3 weeks for most users. We routinely put >300 greeter sessions, 150 uttsc kiosk sessions, on a single SRSS box. We have 2 SRSS boxes. My request is that SRSS be tested and able to scale to some limit which is high enough to be obscene, or documented by Oracle. Be it 25, 50, 100, 250, 1000... we don't entirely care, just need to know. I don't get a very "warm" feeling while watching people having to recompile GDM with custom/ unsupported/ seemingly unknown patches for supported Oracle deployments in order to avoid crippling problems (aka 26D's) in any environment larger than a lab.

In the meantime, I'll investigate getting gdm for b130 recompiled with MAX_CONNECTIONS=100. I'll also have to do the same for OEL 5.6. Setting workers to 32 /etc/opt/SUNWut/auth.props has helped some.
