Oracle 9i and backup exec 9.1

I am trying to get backup exec 9.1 to backup a oracle 9i database but I keep running into the same problem. The job fails because it can’t find the directory. I looked on veritas’s website and they say that the archiving mode on the database needs to be set however the instructions that they give don’t work, neither do oracles. Once I use the shutdown command in SQLPlus, SQLPlus freezes. I usually close that screen and go back through SQLPlus via cmd. After the shutdown, your supposed to use the “startup mount” command however I keep getting the error “ORA-12560: TNS:protocol adapter error”. If anyone can, please help.
