First off hello everyone. I had to find somewhere to get help.

I recently performed an install of Oracle 8i into a new home on Solaris 2.6


All went well and everything is still working.

However I have noticed that all the executables exist twice. The second instance has a zero on the end and is the original.

What happened


lsnrctl
lsnrctl0
dbsnmp
dbsnmp0

I just don't get it. Has anyone seen this happen before. It's clearly just a waste of space. Or is it?
