Ubuntu安装Oracle XE

Web console management
- If you have installed OracleXE database on remote *nix server, you can easily setup a ssh tunnel in order to gain access to a web administration console (since web console is bound to loopback device and therefore unavailable outside to the network):

$ ssh oracle-xe-server -L 8081:localhost:8080

While keeping this proces running (or keep it on background via `screen` or `nohup`), you may now login to Oracle XE web administrations console on your local computer: :8081/apex/. Please notice that your ssh daemon on your local computer should allow TCP forwarding: AllowTcpForwarding yes in your sshd configuration file.
SQL Remote connection management
- By default OracleXe installation does not allow sql network connections to your XE database. To enable it, logon to web management console and enable "Remote connections": "Administration->enable "Available from local server and remote clients"-> press "Apply Changes". The same procedure can also be done from the commandline:

$ sqlplus -S system/password@//localhost/XE EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
EXIT;
/
!

If your SQL client uses a Oracle Instant client installation, the SQL connection can be obtained by entering:

[atrakic@adm2-43 ~]$ sqlplus username/password@//oraclexe.hostname.or.ip//XE

If somewhat connection is refused (due to firewall restrictions) you can use same ssh trick as done previously:

where your sql connection should be like this:

atrakic

User management
Add user
- In order to add single sql user with non-dba privilages to OracleXE execute following commands:

You can run this SQL script with:

Alternatively use web managment console to add new Oracle XE users accordingly.
Delete user
- For deleting a sql users from OracleXE use web management console or execute following commands from the commandline:

ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/
可在命令行创建表空间。
