I am proposing moving from the mainframe to Linux. Problem is that I am not aware of a scheduling product that is available to handle the production code. Currently using CA7. Is there anything out there that accomplishes the same thing? As you can tell, I am NEW to Linux!

View 5 Replies View RelatedThis is my first time to set up a production web server and I got some few questions on our migrations:
1. Our website from the Web Hosting company already gaining 5000000 hits/month and 35000 unique visitors/month, problem is we only have 2x4mb dedicated line here in the office and one IBM x3650 m3 for our LAMP, you think guys its enough to handle that kind of traffic if we start moving our web server here in the office?
2. If I register www.example.com to GoDaddy for example, do I still need to setup a DNS (BIND) server on our side?
3. This is my current Apache config:
Apache/2.2.3 (CentOS) DAV/2 mod_fcgid/2.3.6 mod_auth_kerb/5.1 PHP/5.1.6 mod_python/3.2.8 Python/2.4.3 mod_ssl/2.2.3 OpenSSL/0.9.8e-fips-rhel5 mod_perl/2.0.4 Perl/v5.8.8 with PHP eAccelerator.
Anything to share to increase the performance of the web server?

Please let me know the complete details of a procedure of upgrading a kernel in a production environment?
I have been trying to figure this out for a long time now and can't seem to get it to work. I have three serial ports I need to communicate with. The first one works, but the other two, which have identical product and vendor IDs, do not. This is what I have so far under /etc/udev/rules.d/10-local.rules/

View 2 Replies View RelatedI have played around a little bit with CGROUPS and the fair group scheduler ( using kernel version 2.6.31). When you have CGROUPS in a flat structure, with only one layer from the root-cgroup, everything works as you might expect when setting the cpu.shares parameter, i.e. a fraction of the total. But when I experimented with having deeper levels of CGROUPs it did'nt make any sense sometimes. For example, I had one CGROUP with the maximum number of shares (260000 something) , and two childgroups with quite little shares, 5000. Then I created some cpuhogging processes ( while(1); ) and put most of them in childgroups and one in the parentgroup. The logical thing would be if the parentgroups single process took almost all CPU-time, as it had the maximum number of shares, but instead the processes in the childgroups got the most CPU-time.
I have tried to figure out how it works by looking at the source code, but I can't really understand it. How does the hierarchical structure of the cgroup-tree interact with the flat aspect of it, i.e. siblings? Or do I misunderstand the whole concept?

View 2 Replies View RelatedI've been trying to understand issues that occur during a uClinux distribution build (so I can include such issues in a module I'm writing for students). My process has been to work through errors that occur due to missing packages, then remove the distribution and build it again to uncover what happens.One thing I notice is different sets of warnings within each iteration of making a new build. From the document here (URl...it states, "A typical warning involves a variable being used before its value has been set."
So my question: is there a way to verify that the issue throwing the warning has been resolved by the end of the make build?And, is running make build again an option or could this cause problems within the build directories or image?
We have setup a High Available Cluster on two RHEL 5.4 machines with Redhat Cluster Suite (RHCS) having following configuration.
1. Both machines have Mysql server, Apache web server and Zabbix server.
2. Mysql database and web pages reside in SAN.
3. Active machine holds virtual IP and mounted shared disk.
4. We have also included a script in RHCS which takes care of starting Mysql, Apache and zabbix server on the machine which turns active when cluster switches over.
The above configuration holds good if Active machine goes down as a result of hardware failure or Reboot. What if, If any one service say Apache/Mysql/zabbix running on active hangs or become unresponsive.How can we handle this scenario ? Please advice.

View 2 Replies View RelatedI recently installed another harddrive into my Arch Linux computer. The first time I booted up all worked fine. The next time I restarted my computer though I was greeted with a /dev/sda2 not found error.

cwrsync is a great tool for synching "My Documents" to a network drive in Windows. However it uses a portion of cygwin to do this which uses forward slashes instead of back slashes. So, a manually typed command like the following works great: rsync -r --delete --exclude "My Pictures" "/cygdrive/c/Documents and Settings/demo/My Documents/" /cygdrive/j
However, you cannot put a variable like %userprofile% in this as it comes out like this (and is unrecognized): rsync: change_dir "/cygdrive/C:Documents and Settingsdemo/My Documents" failed: No such file or directory (2)
