SIS locking up / network issue?
Well, I have another issue I'd like ideas on:
Our new student information system (Star Student) has been recently installed and runs on Oracle, using 3 different servers. We access the system through a web browser, though the servers are hosted in our network. (They can be accessed from outside the school system as well). The system uses the Java plugin and requires no higher build than 6 update 7 (of the JRE I believe).
To make a long story somewhat shorter, the program locks up at various times of the day, for various users. I have Star's support team looking at the server logs to see if there is anything noted on that end of things. We recently rolled out new XP machines to admin staff, and some of these users are noticing this lock up issue; however, not all users of Star with these new computers are experiencing it.
I'm very weak in the network troubleshooting area (as is the rest of our staff) and would love any advice on how to troubleshoot this area. I either need to pinpoint the problem or be able to conclusively rule this out as a problem; many higher-up staff believe this to be a network problem as we have had sporadic network issues in the past.
Alternatively, I may be able to run to Java console logger to see if the program is throwing any Java errors. The users don't report any errors coming up; the program simply freezes.
Aside from whatever the servers may suggest (and any Oracle troubleshooting ideas couldn't hurt), what else can I do? Would a packet sniffer (like Snort?) be an idea?
Thanks as always.
