installer permits installation in nfs directory

[Chris Tjepkema]

The install directory is expected to be somewhere under the trafodion userid’s HOME dir. Unfortuantely, this isn’t enforced. So, the installer should be changed to enforce this (as opposed to checking for an NFS disk). Perhaps prompt for only a sub-directory unders HOME to install to. The installer already checks and doesn’t allow the trafodion userid’s HOME dir to be on an NFS disk.

Installer permits installs to nfs mounted /home
Removing with the uninstaller is not very successful. See bottom of this email.

We have both stdout_dtm_0 and stdout_dtm_1

And in $HOME/logs, we have logs for both nodes…

At the end of the command below, we still have trafodion files in $SQ_HOME…
