Installing Cognos 10.2 on RedHat

If you get the following error when installing Cognos on RedHat:
$ ./issetup                                                                                                  
./issetup: error while loading shared libraries: libXm.so.4: cannot open shared object file: No such file or directory

It means that you do not have the 32bit libraries for OpenMotif. (see this link: http://www-01.ibm.com/support/docview.wss?uid=swg21612290)

To fix this, install openmotif.i686 package:
[root@rhel-server-64-x86-64 ~]# yum install openmotif.i686                                                   
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
