Right and you could script this like this:
connect "SYS"/"&&sysPassword" as SYSDBA (this prompts for the password)
set echo on
spool C:\oradba\DropDBNAME.log

shutdown immediate;
startup restrict mount;
drop database;
EXIT


and if you saved this in a file like DropDATABASE.sql you could call it in a command script like this:
SET ORACLE_SID=LIMSME
C:\oracle\Ora10\bin\sqlplus /nolog @C:\oradba\DropDATABASE.sql

Can anyone recommend the top Network Management program for a small IT service company like mine? Does anyone use Kaseya.com or GFI.com? How do they compare to these guys I found recently: N-able N-central remote management
? What is your best take in cost vs performance among those three? I need a good advice please... Thanks in advance!
