Script to find Apache, Java, Jinitiator, Forms version and JVM details for Oracle E-Business Suite 11i

It can be a real pain finding out what version of Apache, Java, JInitiator, Oracle forms etc E-Business Suite 11i / 11 is using. You can do it by hand but here’s a quicker way – with a handy script that Oracle provide. You can get it from My Oracle Support by searching for article ID 466890.1.


NB: You’ll still need to cross-reference the versions of forms and apps you find with the expected versions on My Oracle Support by looking at the readmes and what-not for each patch and/or patchset.


Still beats doing it all by hand though.

How to Get your .Net Framework 4 C# application to use a proxy (with NTLM Authentication)

 I’d been working on an .net framework application that accessed a web resource internal to my organisation – ie, on the internal network where I work. There was no need to use a proxy. Then all of a sudden I was asked to re-write the code for this application to enable it to use a proxy (one that did NTLM authentication) as the resource was being scrapped and we were to buy other resources and access it over the web [via our proxy].

Here’s how I did it. Call this function from your class at a point before it starts making http requests and you should be okay. NB: this code works on our wholly Microsoft Windows network with NTLM authentication everywhere including the proxy server.

This works for me. Haven’t tried it with anything other than IE + XP + IAS though.

Best of luck.

static void setProxy()
{
    WebProxy proxy = (WebProxy)WebProxy.GetDefaultProxy();
    if(proxy.Address != null)
    {
        proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
        WebRequest.DefaultWebProxy = new System.Net.WebProxy(proxy.Address, proxy.BypassProxyOnLocal, proxy.BypassList, proxy.Credentials);
    }
}
I think this was the final code snippet.. Anyway, Give it a blast and let me know how you get on if you want to. Feel free to leave a comment. If you like it then link to it, if you don’t then tell a colleague.. 🙂

At What Speed is my HBA operating?

If you use Redhat Enterprise Linux (5.4 in my case) and you want to know what speed your HBA is operating at then check out the link below for details on how to do it. That pesky systool command raises is useful little head once more.

Microsoft’s Windows Vista – Actually, It’s erm, alright

My new shiny work laptop has arrived with Windows Vista Business premium (I think!)  pre-installed. After everything I’d read in the press and on-line I feared the worst but much to my surprise its actually working quite well. Quelle Horreur. Mind you, it came with Vista Service Pack 2 installed and all I’ve done is let Windows Update run its merry course. Shock horror, its been quite stable, performance has been pretty good. The laptop isn’t over-specked either so its pretty good performance came as a definite surprise. the most difficult thing for me to get to grips with is the control panel – ie, adding/removing software, sorting out other bits and bobs and what not. I borrowed the Missing Manual for Vista which soon got me cruising. An excellent book and a not-so-bad-at-all operating system.

What to do when your Norton Internet Security Subscription Expires: Save some money, that’s what (Don’t renew directly from Symantec..)

My subscription for Norton Internet Security expired yesterday. Normally I’d log in and buy a subscription for another year directly from Symantec. I say normally because this year I am skint and I really need to watch my pennies.So instead i did something a little different. Instead of paying £39.99 online to Symantec I tootled round to my nearest computer store – in my case PC World (www.pcworld.co.uk) – and bought a three license copy of Norton Internet Security for £24.99 (UPDATE: £23 as of September 19th 2011). Hmm, but did you have to reinstall the software I hear you ask. No. I merely clicked on the Renew Subscription button (or whatever it was actually called) and when prompted for a license code i entered the license code from my brand spanking new £24.99 copy. The code was accepted and I got 12 months of antivirus action only I saved £15.01 in the process. Good eh?! I reckon the journey there and back must have cost me around £2. Go on, save yerself some cash.

Be sure to check out the savings first. If you can’t get a cheap copy at your local software shop/store then renewing online is probably the best option for you.

My First Ever Install of TSM Client 6.2.1 on Redhat Enterprise Linux (5.5 32Bit)

For the first time ever I was given the pleasure/task of installing TSM on a couple of the servers I’m responsible for. Our TSM chap had only ever installed the client on Windows so was no help to me whatsoever. I also found IBM’s documentation quite poor – though their Redbooks are okay. Anyway, a few details for you. This is TSM Client 6.2.1 (32bit) running on Redhat Enterprise Linux 5.5. The hardware platform is IBM x3650 with 64GB of RAM. NB: I’m going to use a script to backup TSM so I won’t be setting up the scheduler. Here’s how it went down..

  1. Create a directory to house the TSM tarball and rpms. My
    directory of choice is /root/TSM

[root@myServer ~]# mkdir TSM

[root@myServer ~]# cd TSM

  1. Acquire your TSM installer/tarball/rpms and transfer to
    it/them to /root/TSM using the tool of your choice – be it
    ftp/sftp/scp/cp or whatever other means you have a your disposal.
    I used scp from our master TSM server.

[root@myServer ~]scp tsm@tsmserver:/tsm/6.2.1.0-TIV-TSMBAC-LinuxX86.tar

  1. Untar the TSM client tarball

[root@myServer ~]tar -xf 6.2.1.0-TIV-TSMBAC-LinuxX86.tar

  1. Lets have a look-see what files we have…

[root@myServer TSM]# ls -al

  1. Install the rpms. We need All of the 32bit rpms except for
    TIVsm-HSM.i386.rpm. We’re going to use yum to do
    the install because, well, firstly because I like it and secondly
    it’ll sort out your package dependencies for you.

  1. Now I’ll do a very basic configuration of TSM – please not I will not be setting up the scheduler!

[root@myServer TSM]# cd /opt/tivoli/tsm/client/ba/bin/
[root@myServer bin]# ls -al dsm.*.smp
-r–r–r– 1 root bin 782 Apr 28 2010 dsm.opt.smp
-r–r–r– 1 root bin 971 Apr 28 2010 dsm.sys.smp
[root@myServer bin]# cp dsm.opt.smp dsm.opt
[root@myServer bin]# cp dsm.sys.smp dsm.sys

  1. Edit your dsm.sys file and make it look like the text below – note that I’m using the default port (1500), my TSM Server is 172.24.1.10 – It doesn’t have a DNS entry yet.. – and my TSM Node is called myServer. Change these to suit your environment.

SErvername TSM_A

COMMMethod       TCPip

TCPPort   1500

TCPServeraddress  172.24.1.10

Passwordaccess generate

TCPNodelay        YES

TCPBuffsize       32

TCPWindowsize     64

TXNByteLimit      25600

Nodename  myServer *bogus server name

InclExcl  /opt/tivoli/tsm/client/ba/bin/inclexcl.list

  1. Edit your dsm.opt file and make it look like the text below. My server has only local disk to I’ve set
    Domain to ALL-LOCAL.

SErvername TSM_A

Domain ALL-LOCAL

Subdir YES

  1. Create the include/exclude file (this is completely empty at the moment. Edit this file according to your needs).

[root@myServer bin]# touch inclexcl.list

  1. Connect to the TSM Server for the first time. When Prompted for your “user id” (which should be the same as your NodeName as defined in dsm.sys). Enter your password whenprompted and you should be the proud recipient of a tsm> prompt

[root@myServer bin]# dsmc

  1. Run your first backup. You don’t have to do this but as you’ve installed the backup client you may as well. It’s worth checking with your TSM admin people if it’s ‘safe’ to perform a backup right now.

  1. When you’re finished type ‘quit’ at the tsm prompt to exit out of the TSM client.

tsm>quit

And there you have it. My first ever encounter with a TSM client.I hope you found this useful…

A simple Kickstart File I thought I’d share with you

I recently took delivery of 18 servers each of which required a basic operating system installed and not much else – except for a /oracle filesystem creating. I thought i’d share the kickstart file with you plus one or two other things I needed to do to get kickstart working properly.

  1. setup a webserver to serve the kickstart files. I used IIS: I created a folder to contain the kickstart files on my webserver (D:\kickstart) and create a virtual directory (within an existing site) which pointed at that directory. permissions on the folder and virtual directory were set to read only with no script access.
  2. create the kickstart file (server1.ks) as detailed at the end of this post and save it in d:\kickstart on my webserver
  3. make sure the webserver is started..
  4. boot my server with an install DVD in it (I used an IBM RSA/IMM and mounted an iso image which presented itself to my server as a cd/dvd-rom). Make sure the server boots from the DVD!
  5. At the boot: prompt type linux ip=172.24.1.3 gateway=172.24.1.1 dns=172.24.1.2 netmask=255.255.255.0 ksdevice=eth0 ks=http://your.serv.er/kickstart/server1.ks ksdevice=eth0   NB: your settings will reflect the network settings in your kickstart file!
  6. Sit back and wait.. and your server will build – though on occassion I would be asked to ‘okay’ the disk configuration. Ultimately the process took about 10-15 minutes for me. Joy. If your server can’t find the kickstart file make sure the web server is up and the ethernet port you connect to is eth0 – unfortunately connecting up the other ethernet ports in your server to your switch is the quickest way to determine eth0, especially if you have a load of ethernet ports in your server. Or you can set ksdevice= to eth1, eth2 etc if you are gifted with lots of ethernet interfaces and have the time for re-editing kickstart files and rebooting ad nauseum.
Here’s the contents of my Kickstart file.. the limitations of the blogger.com column makes some lines spread across two or more lines. Please be aware of this if you copy any of the text below.

How To Get The WWID of an HBA with Redhat Enterprise Linux

A bit of a problem presented itself to me the other day. A colleague called me on my mobile and asked me what the WWN of the first HBA in one of our servers was (He pointed out to me that the label on the HBA with this number on it was unreadable). Well, i don’t know about you but i don’t commit that kind of information to memory. So, what to do.. I scratched my head, had a coffee, nosed around the internet for a while and eventually stumbled across this solution.. here goes.. oh, I should tell you the Linux we use is Redhat Enterprise Linux 5.5 ..

Start a terminal sesson on your server as root.


type systool -vc fc_host


you should get some output like this:

Class Device = “host1”


Class Device path = “/sys/class/fc_host/host1”


fabric_name = “0x100000051e36281c”


issue_lip =


node_name = “0x2000001b328709b2”


port_id = “0x018680”


port_name = “0x2100001b328709b2”


port_state = “Online”


port_type = “NPort (fabric via point-to-point)”


speed = “4 Gbit”


supported_classes = “Class 3”


supported_speeds = “1 Gbit, 2 Gbit, 4 Gbit”


symbolic_name = “QLE2462 FW:v5.03.02 DVR:v8.03.01.04.05.05-k”


system_hostname = “”


tgtid_bind_type = “wwpn (World Wide Port Name)”


uevent =

[…SNIP]

Anyway, the line you’re after is the port_name. If you chop ‘0x’ from the front of the port_name value you are left with the WWID/Number of your HBA. It’ll look more like a WWID if you insert a ‘:’ after every second character. So for me 0x2100001b328709b2 becomes 2100001b328709b2 which then becomes 21:00:00:1b:32:87:09:b2.

Voila, you have a WWID.
