If you're not already, I'd recommend using JPackage RPMs. You may even want to add the "Red Hat Developer Suite v.3 for RHEL4" channel in RHN which includes JPackage tomcat5 (5.0 IIRC). Then put your webapps in /var/lib/tomcat5/webapps/ and you're ready to go. If you don't already have it, you need to first install java-1.5.0-sun-devel or another RPM with proper Provides (from Red Hat Extras channel or build your own). Alternatively you can write a shell script that uses runuser to switch to the proper user.

My understanding is that you need a license for every single computer you install RHEL on. It is not the installation really, but in order to use/receive their updates in binary form legally, you must have the appropriate number of licenses. I believe that there is a discounted price available for HPC compute nodes as well. > I am talk specially about RHEL 5.0 or further official release. thanks Another viable option is CentOS . CentOS is a rebuild of RHEL from sources that Red Hat provides in accordance to the GPL, and because they are a true open source company. CentOS takes great care to provide the closest thing you can get to RHEL without buying RHEL. I have been using it for years, both personally and professionally and I've never once had a problem with it. If I am putting software on a system that requires RHEL for support (i.e. Oracle, WebSphere, etc.) I buy RHEL. If I am building a machine that I use for network scanning, interesting uses of apache that Red Hat won't support, or testing machines, I use CentOS. There is no formal CentOS support, but the mailing list is very active. I suppose you could also contact a company that provides commerical support for CentOS as well. Hope this helps.

Message-ID: All- I checked the archives for the past 18 months and didn't see anything related to this, so I thought I would ask for some help. I'm looking for any recommendations people have for good classes/training for Linux performance monitoring and tuning. A couple different companies appear to offer a RH442 "Enterprise System Monitoring and Performance Tuning" class. Does anyone on the list have experience with that class? It looks like Red Hat uses Unitek, but I see there is a least one other company (Netwind Learning Center) that's also offering the same course. Are either of those companies recommended (or to be avoided)? Anyone have a particularly positive experience with an instructor for that class, so that I should try get the same instructor? We have mainly RHEL here, a little 2.1 remaining but mostly 3-5 at this point, so it's fine if the class is tailored toward Red Hat -- it's not a requirement, though. If there's another class out there that would be better, I would love to know about it. I'm not an RHCE, but I have 17 years of experience managing UNIX systems, and a few years of experience managing Red Hat systems in a production environment. There are plenty of areas in system administration where I'm strong, but I've never been particularly strong in the performance monitoring and tuning area, and I would like to change that. I'm also toying with the idea of going for RHD236 "Kernel Internals" instead, since I'm a casual though comfortable C programmer, and a deeper understanding of the Linux kernel would certainly be beneficial for performance monitoring. Feedback and recommendations would be much appreciated, Tim -- Tim Mooney Tim.Mooney at ndsu.edu Information Technology Services (701) 231-1076 (Voice) Room 242-J6, IACC Building (701) 231-8541 (Fax) North Dakota State University, Fargo, ND 58105-5164 From jwang at dataseekonline.com Sat Jan 26 00:01:31 2008 From: jwang at dataseekonline.com (John Wang) Date: Fri, 25 Jan 2008 18:01:31 -0600 Subject: Starting services the right way.

In-Reply-To: References: Message-ID: <479C8BA2.6060507@hp.com> Hi Tim, The RH442 Red Hat class is part of the RHCA (Red Hat Certified Architect) track; I found it to be a very good overview of performance tuning in general, and of tuning RHEL specifically. There are also a number of good texts on the subject, including the two described in the Linux Journal article at http://www.linuxjournal.com/article/8516.
