Hello folks, I am relatively new to Cognos Administration. Can someone post steps installing Cognos on Linux server?

Thanks!!

Hi,

The Installation and Configuration Guide covers Windows, unix and Linux installs:

Cheers!

Thanks MF! I am aware of the installation guide..However after doing some research online, I noticed that the installation on Linux is not as simple as Windows and that there are additional steps we need to do in Linux which are not completely covered in the IBM guide, hence the request for steps if any members have done an Linux installation.

Yes, the installation on linux box is little difficult than windows. Specially when you are installing it on remote server. When my team installed it on linux, i was part of it but couldn't do much on that. They faced many problems. We were installing it on redhat linux by accessing it via putty. you may need X window software to do this. Also 32 and 64 bit version might create some problem. you need to carefully choose the version your machine can support. Then your config files including cogstartup.xml will need to be modified. Sometimes you might run out of memory if server space is low. Lots of things you might encounter and need to take in consider. So plan accordingly, it might take a month to install and run it fully even you dedicate yourself completely to it. There is no simple and straight forward steps for installing cognos. If you complete this successfully, it will be a great learning for you. Good luck.

Thanks Deepak! Installation on linux is a pain.. :( We do use VNC viewer and are installing it on Redhat Linux. I will post how the upgrade goes once its completed.

I have to disagree with this...

Installation is quite easy when you have
- experienced linux administrator (understands X11 window system, 32bit/64bit, environment variables, ulimit and other basic things)
- experienced cognos architect: Understands at what parts of cognos are always 32bit (these days the cognos installation itself is always 64bit)
- someone who knows and understands the database libraries that are needed

"Classic" pitfalls are, at least with oracle:
- not using 32bit oracle client libraries when using Cognos Classic query mode
- not using 32bit apache httpd when using 32bit cognos gateway modules
  (the OS defaults to 64bit apache httpd)
- not setting ulimit high enough (ulimit -n 65536 will save you from many weird problems)
- not using 64bit java

Linux is quite nice when you have to have multiple different versions of cognos using multiple different database client versions that must be isolated from each other. Or when you must do the installation as an user with no administrator rights . Nothing that can't be done using windows, just easier...

Wonderful post! Thank you!!! :)

Hi,

I agree if we have both architect it is easy. But in my example , i have experience in installing in windows but not in linux. So i have to see the IBM guide, In this scenario it does not give complete details. Also i am in need to install in silent mode. Cutomer is not allowing GUI.  They are asking Cognos admin has to explore the linux and install. In this case , i am in need of silent installation steps or some guidance. does any one has come across this ?

I just finished Cognos BI deployments on RHEL 7 x86_64 and PPC64  Architectures.  Where exaclty are you stuck in your deployment?
