问题
I am trying to create to connect with oracle sqlplus. When I login with:
User: sys as sysdba
Pass:
It says Connected to an idle instance.
And when I try to create a table, it gives the error
ORA-01034: Oracle not available
Process ID: 0
Session ID: 0 Serial number: 0
Why is it not creating the table?
回答1:
First - and most importantly:
Only use the SYS account for DBA work. Never use it for "regular" work (e.g. creating tables) - use a dedicated regular user account for that.
Secondly: "connected to an idle instance" means Oracle was not started. So as you are already connected as sysdba (again: which you should only do for DBA tasks) you need to start Oracle using the command
startup
in SQL*Plus.
Then log off, log in with a regular user and create your table.
For details see the manual:
- Startup Command
- Administrator's Guide
