General :: Install Web Service Server On Blade System?
Jun 30, 2011
I need to install a webservice server coding in java & running in JBoss AS onto a blade server with Linux OS. Anybody knows what way to make use all the power of that blade? Or just install it as install on other system? In my point of view, there are two ways I could do: Implement a webservice "server" which accept the incoming request, and then deliver to its "client" webservice. So we would run one instance of server and many instance of client. Other way is just improve the current implementation, accept incoming request and try to use multi-thread as many as possible to maximum the performance of the blade server.
We have done an installation on a blade server (HP) for RHEL4.5.
The server have an HP smart array 2200 controller and during installation it can see the controller and disks just fine.
The installation completes up to the point where the system needs to reboot , however after the reboot it does not start up again and get stuck at the message: "Trying to boot from drive c:"
We used the rescue option to mount the installation and cant find nythign wrong, even with the grub setup (except that it points to hd96 as its primary disk). we tried changing this to hd0 as well but still no luck.
After about 3 installations we are still not having any luck.
I have a IBM BladeCenter HS21 and im planning to load debian lenny.pls let me know it is possible to load debian in ibm blade server.does ibm support debian i386.
both blades are running RedHat 4 (nahant update 4). Blade A returns Linux 2.6.9-42.ELsmp to the uname command and apache starts up without issues. Blade B returns Linux 2.6.9-89.ELlargesmp to the uname command and fails with the following error: Cannot load /opt/httpd/03/modules/mod_access.so into server: /opt/httpd/03/modules/mod_access.so: cannot open shared object file: No such file or directory
I have confirmed that the modules are present (actually a symlink to a valid directory) and have the correct permissions. Why can't I get Blade B to start?
I can login with my other machine to my server but wehen I start hte server it does not fail. seem sto work, but windows see nothing. How to give the passwords to my users?
I have been given a task to install samba server from my local PC in an another PC which is a linux server.The linux server is in my own comapny and i have been given its ip address and root login password.I dont know how to install that samba server from my own PC.
I am using centos 5.5 x85_64 2.6.18-194.3.1.el5 The server is hanging at start up due to the follwoing error
udevd[746] nss_ldap reconnecting to LDAP server (sleeping 4 seconds) udevd[746] failed to bind to LDAP ser er ldap://192.168.0.100 cant contact ldap
It fails and then tries again, and again, each time increasing the sleep time. This is happening before network sercvices are started so ther is no way it can connect to ldap. anyone know a way to fix this problem?
I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
i have a IBM IBM BladeCenter 8677-3RU it currently doesnt have any ISO installed on the chassis since i dont know what to installed into it. The blade has 14 JS21 2 X 2.7GHZ PROCESSORS 2-socket single-core 64-bit PowerPC 970MP
For some reason my Sandisk Cruzer Blade 8GB is not being recognised in Mint 11.It did work for a short period but no longer does so.Is there some command line I can use to search for it ?it simple as I am in the Newby category as far as Linux is concerned.
I'm using pyqt3 for my app and am lost on even how to attempt this task... On a vinyl cutter to have the blade pivot it must be offset from the center of the shaft it's on so say for example a .25mm offset would leave a .25mm unwanted vinyl attachment when the cutting is done. I somehow have to average or extrapolate that .25mm xy coordinate and add it to the hpgl plot file as a PUx,y; command? I have enclosed a simple sample file that has three images in it. In the corresponding hpgl file everything between the PU commands that are starting with PD are the code for that image (star for eg the pu to move to next image and then all PD for the next image and so on, so once the formula or procedure is figured out it can be applied to as many images there are in the file. Placing the new command at the head of each image PD group. Since there are absolute and relative cutters I enclosed the same exact plot for both types as the coordinates on relative can be negative numbers. Only PU and PD commands and a ";" as a command delimiter as sometimes many commands are on one line.The offset variable will come from a spinbox but .25 is good for an example.
My Ubuntu 9.10 Server does not automatically get an ip address at start up and I have to run
Code: sudo dhclient
every time so I it connects to the network, gets an ip etc. This is fine so long as I am physically present. If I am accessing it remotely using SSH and reboot the system there's no way I can connect back again untill someone runs a sudo dhclient on the machine.
No I am trying to add dhclient to startup automatically. I was hoping to put it in /etc/rc2.d but to be able to run the script must be present in /etc/init.d. The dhclient command is located in /sbin
Creating a sym link in etc/init.d to point to /sbin/dhclient hasn't worked for me so far. I can't copy the command to /etc/init.d before running
Code: update-rc.d dhclient default?? How else do I have it run at system start?
I am an intermediate linux user. However, I know nothing about solaris. I am trying to install Debian Sparc on a sun blade 2500 workstation. I was told it should work. I am able to go through the debian installation process but when the box reboots it does not boot into Debian. I have now gone through the debian install process several times and now it saids there are too many primary partitions. I tried a rescue install but it saids there are no partitions installed on disk? What am I doing wrong? I am curious if I need to pass a specific argument at the command line to boot into silo? I cannot find any relevant guidance online about this problem and I cannot believe I am the only one to stumble here.
When trying to install Debian 6.02 from a boot cd, the boot halts with the error message Kernel panic - not syncing: No init found. Try passing init= option to kernel. In looking for a solution I see a great deal about this problem occurring after messy upgrades and the like, but when when booting from a cd downloaded right from the debian website.
I've got 10.04 installed on my Blade 1000 workstation. Installed 6.06 first and worked my way up as per other postings. See attached cookbooks I wrote. Framebuffer is Elite3D-lite, and I have done the afbinit install. Using Xorg w/ Gnome and other windowing software to eliminate the possibility it is Gnome. From what I understand, Ubuntu does not require a custom X11 conf file like OpenBSD.
Current screen output shows large vertical stripes, where the stripes overlay on top of the GNOME desktop. Inside the stripes are the prior boot screen output of Ubuntu 10.04. When the screen saver kicks in, the Gnome desktop disappears, but the blue 10.04 stays visible. Mouse cursor moves across the screen, under each stripe as it goes.
My knowledge of framebuffers is limited. Would this then imply that the framebuffer is not fully "refreshing"? The screen does not provide full width even though the correct OpenBoot monitor configuration is set. Haven't found any mention of this issue from other Ubuntu/Linuxes Sparc users. Attached the X11 log. Looking at the log, I suspect this will need a custom X11 config file.
Im trying to install CACTI EZ on a HP Proliant Blade 460c G6. But im having problem with detecting the hard disk. CACTI EZ installation has the drivers for this and loads the driver itself. But when it now detects for the drive, it has the error "Drive not Found".Do you have bootable CD (iso image) that can load the drivers for Cent OS 5 for HP Proliant Blade 460c G6 server.
dear, in centos / fedora, I can config to start a permanent vnc session by setting the /etc/sysconfig/vncserver file when the system starts. Is there any similar configuration in opensuse which give me a permanent session?
i have added a tomcat startup service using chkconfig. I have set up JAVA_HOME and JRE_HOME as well ass alternatives to point to the correct location.I have an init script in /etc/init.d. When i start the tomcat service using [ /etc/init.d/<x> start ] everything works fine and the environment variables for JAVA_HOME and JRE_HOME are used correctly.Now i added the service <x> using chkconfig --add so that it can start on boot up. But now the service does not use the system environment variable for JAVA and JRE setup by me.Also after complete bootup if i try to start the service using [ service <x> start] the environment variable in the shell are not used. don't want to exclusively declare variables for JAVA_HOME and JRE_HOME in the init script.
I'm trying to produce a alphabetic, non-repetitive list of all System service calls in all c files located in a folder. Here's what I got so far. grep -ow '[A-Za-z]*SYS[$][A-Za-z]*' *.c | sort Which produces all system service calls in alphabetic order I just need to find out how to make it non-repetitive.
i am looking for ideas to set up a calender/ scheduling system (or online service) for a doctor's office to set up patient appointments. i would like to set it up so that only the doctor, technician and receptionist can access it and set up appointments from 3 different computers.
I have been playing with chroot to build packages.I am wondering about the limits or caveats of using chroot to mix operating systems. For example, what should I beware if I use 12.2 and chroot a 13.1 system? Or if I use 13.1 and chroot a 12.2 system? After all, the chroot does inherit some attributes of the parent system.There is the noticeable difference of kernel versions. For that one reason I'm thinking that mixing system versions might be frustrating.
My focus is building packages, not running an alternate operating system or a service such as ssh. I realize that building packages as root in a chroot potentially compromises security but that is not my focus.I am aware that a chroot is not a true virtual system.A virtual machine is an option, but in this thread I'm curious about the limitations of chroot. I find building packages in my virtual machines much slower than actual hardware, even with a dual core. Hence my interest in chroot
