To login to your Oracle account using our supported environment:
statements that you need to enter are in bold. When the prompt SQL> is returned, your Oracle login was successful!
- You need an ssh client. We recommend Putty. For Mac users use the Terminal app.
- Launch your ssh client and open a secured connection to the remote host: remote.eos.ncsu.edu.
- login: <enter your Unity ID>
- Password: <enter your Unity password>
- eos% add oracle11
- eos% sqlplus

Important: We highly recommend users to change their Oracle passwords asap as follows:
Note: (special characters in passwords are allowed except "spaces" or leading/trailing @ symbol.)
Changing password for username
Retype new password:
Retrieve Session Privileges:
- login to your Oracle account
- at the SQL> prompt type:
select * from session_privs;
Retrieve Session Roles:
select * from session_roles;
- ssh to remote.eos.ncsu.edu
- Sqlplus to your oracle account
- execute the utlxplan.sql script as follows:
For more information about Autotrace check Oracle's User's Guide.
The privileges a user can grant include these( On the user's tables, views, and materialized views):
- UPDATE (all or specific columns)
For example, the user JOE gives MOE SELECT access to the NAMES table:
grant select on NAMES to MOE;
MOE can now view all records on NAMES with:
select * from JOE.NAMES;
To revoke access:
revoke select on NAMES from MOE;
The easiest way to export data is by invoking the "exp" utility and then let it prompt you what you want to export. To run the export utility:
- ssh to remote.eos.ncsu.edu
- add oracle
- Execute the exp utility by typing the command: /afs/bp/dist/oracle9i/OraHome1/bin/exp and press <enter>
- user-name: UnityID@orcl
- Password: <enter your Oracle password>
- answer the prompted questions. When asked for the output file, make sure to write the output to a location where you have write permissions such as your own home unity or eos directory.
Note: The import utility, "imp" works similarly as the exp utility.

1) I inserted a new record into a table with the "insert" sql command, but the table doesn't show that record.
Issue the sql command: commit; after your insert statement.
2) How to change my Oracle password?
3) How to move to Another User with Connect
This is the most secured way of doing it. Suppressing the password, the system will prompt you to enter a password.
4) How do I display my user tablespace disk quota?
SQL> SELECT * FROM USER_TS_QUOTAS;
5) How do I connect to the Oracle server from a third party client or development tool?
You will need the Oracle client installed on your PC. The client can be downloaded from Oracle's Web site. Currently our Oracle server is running under version 10g Release 1, so make sure you download a client that is compatible with it. Add an entry to your tnsnames.ora file (this file should be on your hard drive under: \oracle\ora90\network\admin) as follows:
(ADDRESS = (PROTOCOL = TCP)(HOST = orca.csc.ncsu.edu)(PORT = 1521))
(SERVICE_NAME = orcl.csc.ncsu.edu)
Refer to your third-party client or programming tool documentation for further connectivity instructions.
