title: Can't finish oracle 11g installation on Ubuntu 16.04 vbox - files not found
body: <p>I have VirtualBox running on Windows 10 host and I created a Ubuntu 16.04 (32-bit) vm where I'm trying to install Oracle 11gR2 (32-bit) database but I can not finish the installation.</p>
  
  <p>The issues I'm having are:</p>
  
  <p>1) at the Prerequisites Check I have a message saying about the value for kernel parameter "semmni" being 0 while it should be 128 (I added such parameter to /etc/sysctl.conf but that was the thing to apparently because the message is still displayed); I check the 'Ignore All' in the wizard so I can move on but...</p>
  
  <p>2) During the installation 'Link binaries' stage (under progress bar it says 'Linking dg4odbc Executables') the process is interrupted by message about a file being missing 'dbhome/rdbms/lib/ins_rdbms.mk'. I can click 'continue' but this only brings another message about another file being missing and that is '/dbhome/precomp/lib/ins_precomp.mk'. If I click 'continue' again I see the first message again.</p>
  
  <p>I tried to google both files but no success - I still know nothing about how to deal with this. Anybody can help?</p>
