I am facing error "ORA-12518: TNS:listener could not hand off client connection" while using 10G R2 XE edition on Win 7 64bit.
I know XE is 32bit, my OS is 64bit but it was working properly till last week when I had to format my system. Now its not working.
I know there have been similar discussions on this topic, but none resolution worked for me.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
