Ubuntu Servers :: Ubuntu Server Vs. Oracle Enterprise Linux?
Oct 15, 2010
Having been a long-time Linux supporter, it was a no-brainer for me to push Linux as the OS when it was time to move my company's website(s) from an external host to an internal server. My company ponied up the bucks for an HP Proliant DL180 G5 server (this was about a year ago) upon which I installed Slackware 12.1 (I kinda default to Slackware, although in the past I've also used RedHat on the server and openSUSE on the desktop).
Well, it's now time to upgrade the OS on the server. Perhaps I'm a little late to the game on this, but I just recently found out about Oracle Enterprise Linux 5.5. Bad Oracle ju-ju aside, it looked to be a very good and stable server distro, especially when you consider the availability of Oracle support for it. So I've since installed OEL to a non-production server and have been testing it out.It looks to be a good match for my needs.
However, since installing OEL on my test server I've installed Ubuntu Desktop 10.10 on my home desktop (a 1.86ghz Intel Core 2 Duo HP xw4400 workstation) and in a VirtualBox VM on my work desktop (a 3.2ghz Intel Core i3 iMac) and... holy crap, it's the best desktop Linux I've ever had the pleasure of using. It will certainly replace Slackware as my default "go-to" Linux distro. Which has made me wonder about the Ubuntu Server offering and if it might not be a better fit for my webserver in the same way that Ubuntu Desktop is a better fit for my workstation.
Unfortunately, I don't have the time to pull down another server distro, install it, and test it unless I'm reasonably certain that it's going to give OEL a run for its money. So I turn to the forums and the knowledge of the users who frequent them: is Ubuntu Server a strong enough contender to OEL that I should take a more serious look at it? Or, like I'm hearing about the latest Ubuntu Netbook edition, would it not be worth my time if I'm happy with OEL so far?
I'm trying to configure DNS on Oracle Enterprise Linux 5.4 - Kernel 2.6.18-128.el5. When I restart the named service, I'm not getting any errors. But service is showing Failed. What could be the reason?
I have installed Redhat Enterprise Linux Server 5 on my laptop. I want to install Oracle 10g database on RHEL5 server. I want to know whether any additional rpm's need to install before installing the Oracle 10g.
I want to enable the communication b/n ibm tsm server and ESX server . for that reason i want instal /etc/init.d/vsftpd in my sys. But iam unable to find the link which can provide me this software [/COLOR].
We are in the process of testing SLES 10 SP1 installation, onto a new system.
Initially the installation got failed at the start giving following error :
"Could not find the SUSE Linux Enterprise Server 10 Installation CD. Activating Manual setup program."
What is interesting to notice is , if we use SLES 10 SP2 to boot the system upto the Installation menu and then replace the CD with SLES 10 SP1 media, the installation proceeds as normal without any error.
Not sure that could be the problematic thing over here. Does it mean with SP1 , no cdrom/cd or hard disk gets detected ?
I am trying to install guest additions on Oracle Enterprise Linux Update 5. Whenever I try to the run VBoxLinuxAdditions-x86.run script I get the following problem:
erifying archive integrity.All good. Uncompressing VirtualBox 2.0.0 Guest Additions for Linux installation. VirtualBox 3.0.6 Guest Additions installation install the build and header files for your current Linux kernel. The current kernel version is 2.6.18-164.el5PAE Problems were found which would prevent the Guest Additions from installing. correct these problems and try again. I also tried yum install using the following commands without any luck:
yum install kernel-devel kernel-headers-`uname -r` Following are the package information of my kernel-devel and headers: > rpm -q kernel-devel kernel-devel-2.6.18-164.el5 > rpm -q kernel-headers kernel-headers-2.6.18-164.el5
I have been spending a couple of hours already on how to fix this but I still couldnt get to install this.
I have several hosts running either TinyCore or Oracle Enterprise Linux that are using DHCP to get their IP addresses and other network configuration.I'd like to use DHCP to pass in some other information, but I don't know how to get DHCP options, including custom options, in a CLI script.
I am going to install Oracle RAC on two Servers, With shared SAN storage (Servers and Storage is IBM) OS = RHEL 5u5 x64 bit
And we used multipathing mechanism and created multipathing devices. i.e. /dev/mapper/mpath1. Then I created raw device /dev/raw/raw1 of this /dev/mapper/mpath1 Block device as per pre-reqs for Oracle Cluster. Every thing looks good, But we faced the performance issue as under.
when we run command : #dd if=/dev/zero of=/dev/mapper/mpath1 bs=1024 count=1000 the writing rate is approx. 34 MB/s But If we run command #dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=1000 the writing rate is very slow like 253 KB/s
I'm try to download Evaluation Red Hat Enterprise Linux Desktop 6 from Red Hat but It shows.Existing Evaluation Subscription. It appears that you have already activated an evaluation of 30-day Unsupported Evaluation Red Hat Enterprise Linux (Up to 2 Sockets).Please contact sales for more information.
Currently I am installing oracle 10g release 2 with Red hat Linux 4.I am getting the following error.
Exception Name: MakefileException
Exception String: Error in invoking target 'ntcontab.o' of makefile '/home/oracle/oracle_10.2/network/lib/ins_net_client.mk'. In forum I saw this kind of post and I did all the steps, then also getting the error.
I hav successfully installed RHEL5.1 on my system. I downloaded flash player from Adobe website. I chose RPM from the download type. Now, I can find an icon on my GUI for the flash player. When I right-click the icon and click on "Open with software installer", I was able to install flash player. Even the system showed that the software has been installed. But still when I issue the command rpm -qi flash the output says that flash is not installed.
Is there any correct way to install the rpm package. I even tried to install using rpm -ivh <flash player pkg name> even that did'nt work... I have another query... where does the package gets installed when I download RPM's or any other software from the internet.. I want to know the path where the pkgs will be sotred...
My application is installed on root of RH enterprise 5 and is run via user on the same machine. This need ssh without password from the user.
i do the following : 1. run ssh-keygen in .ssh directory of the user. 2. copy the id_rsa.pub as the authorized-keys in the root's .ssh directory 3 chmod 600 to the authorized_keys 4.restart the machine 5. login from the user and ssh SER ( SER is the entry in the /etc/hosts with the ip address of the machine) 6 It still prompt for the password
How can i ssh from the user to the machine without password.

have Unix and Windows experience. So will need some hand-holding.Need help getting my wireless network to work on my newly installed Oracle Linux on Dell laptop.Not sure what wireless card is installed, or it's mac address (though I can boot into windows and get that info I don't want to - it'll be kind of a let down if I can't fix it all thru Linux).Install has detected a Broadcom wired card, but not the wireless. Funny thing is that it detected the Bluetooth
I have some Oracle (Unbreakable|Enterprise) Linux systems, mostly running v5.4. I'd like to migrate them to CentOS 5.4 (or 5.5... I'm not picky about that).Is it as simple as updating the repo files in /etc/yum.repos.d, and issuing 'yum upgrade', or is there further magic involved?
I am looking for some monitoring tools (such as disk usage,memory usage, cpu,etc) for my linux machines. I came across two tools, cacti and splunk.Which one is better ? It will be nice if you can also let me know the reason.
I have read just about every page about the UEC project, and I now know everything about it, except... WHAT IT DOES! I can't seem to find a coherent example of what it does. To the best of my understanding, it runs a virtual machine across multiple servers. Allowing the VM to use the RAM, CPU, and HDD resourced on all servers involved.
