I've installed Oracle on a Unix machine, and tried to setup a database on it. This was all scripted, so it's hard to find out where it went wrong.

Now, the Oracle processes are running, but I can't log in to sqlplus.

There's an error in the database create logfile, saying
ORA-01857: not a valid time zone
Undoing the database creation. Please wait...

The timezone on the machine is Mideast/Riyadh.

Can anyone help???????
