HELP - Resource/Performance Monitoring Script - Red Hat Enterprise Linux Server
Hi all,
-------------------------
Linux OS Version/Release:
-------------------------
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
Linux <hostname> 2.6.18-194.8.1.el5 #1 SMP Wed Jun 23 10:52:51 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
I have a server that hosts 30+ Oracle databases. Each database has its own set of scripts that shuts down the database and start the database. Things has been working "smoothly" in the last couple of months until this week.
My log in most cases shows errors like the ones below:
cannot fork [Resource temporarily unavailable]
Connection reset by peer
I am 100% sure that the scripts are not at fault since it has been working with no errors for months. I want to monitor the server for what resource or configurations I have to tweak to get around this problem if possible, am I exceeding my ulimit settings running out of process, out of memory/swap space etc?
I wish I could stay up 24x7 to monitor to monitor the server but I can't. Can anyone please advise if there is any monitoring script available somewhere that I can put in cron to temporarily monitor the server for resource issues, for example memory used/left, swap space used/left, ulimit-num-process used/left, nofiles used/left etc.
Any help/advise/suggestion will be much appreciated. Thanks in advance.

The Adobe Flash Player does not work in my Enterprise Red Hat Linux.
It instructs me to download the Flash Player which I have done. However, it does not install. Do I have a GUI in Red Hat that I can use or do I have to do it via command line.
Would appreciate any help.
Thanks,
