Problem: WebSphere Portal installation from a mounted directory fails during profile creation
Issue
You attempt to install IBM WebSphere Portal v8.5 from a mounted directory and the installation fails during profile creation. You are using the silent install option along with a response file.
Resolution
From the command line, use the UNIX command nohup. This command ignores the SIGHUP signal and allows the installation to complete successfully. The syntax is:
nohup ./install.bat -options {responsefile_path}
