When installing Oracle 11gR2 on Solaris, you may get this warning when run ./runInstaller and the installation may hang at 86% and never complete.
If you install Oracle via putty and Xming, then you should install Xming-font and configure the file fonts-dir in Xming installation dir.
Edit file C:\Program files\Xming\fonts-dir and add the lines:
C:\Program files\Xming\fonts\TTF
C:\Program files\Xming\fonts\misc
C:\Program files\Xming\fonts\75dpi
Edit file C:\Program files\Xming\fonts-dir and add the lines:
C:\Program files\Xming\fonts\TTF
C:\Program files\Xming\fonts\misc
C:\Program files\Xming\fonts\75dpi
Note: with Windows 64bit, to make sure it works well, when installing Xming please make sure that the installation directory is C:\Program files\Xming, not C:\Program files (x86)\Xming.
After installing Xming-font, run ./runInstaller again the warning may appear in your putty console but it's ok. The installation will pass 86% and run Oracle configuration assistant.
