Code:
[root@borg ~]# ps -ef | grep pmon
oracle   26079     1  0 18:31 ?        00:00:03 ora_pmon_borg
root     28679 28619  0 23:05 pts/2    00:00:00 grep pmon
Set $ORACLE_SID="borg" instead of "BORG" and now we are getting somewhere:

Code:
[oracle@borg root]$ sqlplus '/ as sysdba'

I'll change all the BORG references to borg and see if that makes a difference. More on this tomorrow. Thanks for the help so far.
