Hi
I have installed oracle on my c:\ drive and created database for example of name 'abc'.
now when i go to sqlplus editor and create
a table 'customers' and i do desc command i see all its columns,the question is: is that table 'customers' now in that database 'abc'?
How do i know that?is there a sql statement to show me all tables in that database 'abc'?(sample code plz).
I'm sure i can create many databases too other than 'abc' ...is that right?
To connect to 'abc' is database url should be like the following:
"jdbc racle:thin@localhost:1521:abc"
is that right?
Thanks for your time.

Hi all
I'm trying to create new domain with weblogic other than the default(mydomain),the problem is when i start weblogic as soon as gets to the point where to load the configuration file it exits completly.
When i check "all domain configuration"in the console i see that the new damain is active=false
is not as mydomain active=true.
please any help with that,here are my scripts to start weblogic:
startWebLogic.cmd

@rem WebLogic Server. This variable must point to the
