Attempting to install ehealth on Windows server fails at the Database creation stage with the following error: 

Wed 18:12:38 Unable to add Oracle Listener for D:/oracle/Oracle.11.2 
nhCreateDb FAILED: log file is FAR TOO SMALL (624 vs 15000+ lines): 

Even after performing the steps highlighted in TEC1264456 the reinstallation still fails with the same error.


eHealth 6.3.2 and above.


A previous installation of eHealth (either standalone, distributed or failover) has not been entirely removed.

Manually search for all eHealth and Oracle related keys under:


Take a backup and then delete these eHealth and Oracle keys.
