We have a problem connecting to a database that we have not seen before, and I am wondering if any else has encountered it. OS: Windows2003 32-bit Database Version: 9.2.0.8 Only one Oracle Home on the box There are six databases running on this server. We can connect to five of them just fine. When setting ORACLE_SID to the problem SID, and trying "Connect sys as sysdba" we get "ORA-12546: TNS:permission denied" When we do "Connect sys@sidname as sysdba" it connects fine. Why would one database have a problem when the others all work?
