Hi,
Just done a fresh install on a "vrigin" Windows 2008 (32 bit) server of 11G XE. All appears to work fine can access via the web front end, connect to Apex etc.
I want to upgrade the Apex to latest version so need to run some scripts from SQLPlus .. can't connect, get the error message in the title.
Have done exactly the same install and procedure on Windows 7 laptop and Windows 2008 (64 bit server) with no issue ... any ideas why this install would be different ??
