How to Convert An Image-Based Guest To An LVM-Based Guest
1. using sqlplus with no login name
sqlplus /nolog
Should set $ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server
2. startup db
sqlplus /nolog
connect / as sysdba
startup
exit
3. shutdown db
sqlplus /nolog
connect / as sysdba
shutdown immediate
exit
4. enabling remote http connection
EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
5. change password:
ALTER USER SYS IDENTIFIED BY newpassword;
ALTER USER SYSTEM IDENTIFIED BY newpassword;
6. connect remote oracle server with sqlplus
connect sys/123@10.1.1.8/XE as sysdba
7. data file type:
root@fs:/usr/lib/oracle/xe/oradata/XE# ls -ltr
total 1078224
-rw-r----- 1 oracle dba 104865792 2007-08-12 16:07 users.dbf
-rw-r----- 1 oracle dba 20979712 2007-08-12 16:45 temp.dbf
-rw-r----- 1 oracle dba 450895872 2007-08-12 22:30 sysaux.dbf
-rw-r----- 1 oracle dba 356524032 2007-08-12 22:38 system.dbf

SYSTEM
This tablespace is automatically created when Oracle Database XE is installed. It contains the data dictionary, which is the central set of tables and views used as a read-only reference for the database. It also contains various tables and views that contain administrative information about the database. These are all contained in the SYS schema, and can be accessed only by user SYS or other administrative users with the required privilege.
SYSAUX
This is an auxiliary tablespace to the SYSTEM tablespace, and is also automatically created upon installation. Some database components and products use this tablespace. The HR sample schema is also stored in the SYSAUX tablespace.
TEMP
This tablespace stores temporary data generated when processing SQL statements. For example, this tablespace is used for sort work space. The TEMP tablespace is specified as the default temporary tablespace for every user.
UNDO
This is the tablespace used by the database to store undo information.
USERS
This tablespace is used to store permanent user objects and data. In Oracle Database XE, USERS is the assigned default tablespace for all users except the SYS user, which has the default permanent tablespace of SYSTEM.
8. create your own db;
