ECC5 installation: Error msg during Post Processing Oracle DataBase

Hello Gurus:

I had installed Java and Oracle DB on C: drive which installed successfully.

I was installing SAP on D: drive. This msg came up.It happened after five hours of final installation when it goes stage by stage in the final run.

Switched to User:trbadm

Working directory changed to C:\ProgramFiles\sapinst_instdir\ECC_50_ABAP_NUC\DB

Installation had to be aborted.

Can you kindly provide a fix for it what can be possibly wrong?
