| =head1   db2install 
 | |
| 
 | |
|  This postscript installs and sets up db2 on a client machine, usually a Service Node
 | |
|  or a login node. This script can only be used to automatically install an
 | |
|  AIX 6.1 or 7.1,  or a Linux Redhat5 or Redhat6 Client. 
 | |
|  Note: the db2 code must be in a mountable directory  defined by the
 | |
|  db2installloc attribute in the site table.
 | |
|  The perl-DBD-DB2 code should have been installed during the xCAT install from 
 | |
|  the AIX or Linux xCAT deps package for AIX6.1 or 7.1 or Redhat5 or Redhat 6.
 | |
|  More information can be obtained from the xCAT http://xcat.svn.sourceforge.net/viewvc/xcat/xcat-core/trunk/xCAT-client/share/doc/xCAT2SetupDB2.pdf.
