Oracle Enterprise Manager Database Control provides a Web-based user interface that you can use to monitor, administer, and maintain an Oracle database, including Automatic Storage Management.
To log in to Oracle Enterprise Manager 10g Database:
Open your Web browser and enter the following URL
http://hostname:port/em
In a default installation, the port number is 1158. If you are unsure of the correct port number to use, look for the following line in the ORACLE_BASE\ORACLE_HOME\install\portlist.ini file:
Enterprise Manager Console HTTP Port (db_name) = port
Note:
The
portlist.ini file if not updated if you change a port number after you install Oracle Database. "Changing the Oracle Enterprise Manager Database Console Ports" explains how to find the Oracle Enterprise Manager Database Control port number in this situationFor example, if you installed the database on a host computer named mgmt42, and the port number listed in the portlist.ini file is 5500, then enter the following URL:
http://mgmt42:5500/em
Enterprise Manager displays the Database Control Login Page.
Log in to the database using the SYSMAN database user account. Enterprise Manager displays the Oracle Database home page.
Use the password you specified for the SYSMAN account during the Oracle Database installation.

SYSTEM_DRIVE:\> sqlplus user_name/password
For example, to log on as SYSTEM using the password welcome, you enter:
SYSTEM_DRIVE:\> sqlplus system/welcome
If you are logging on as SYS, you would need to connect as SYSDBA:
SYSTEM_DRIVE:\> sqlplus sys/welcome as sysdba
To start iSQL*Plus:
Open your Web browser and enter the following URL:
http://hostname:port/isqlplus
If you are unsure of the correct port number to use, check the ORACLE_BASE\ORACLE_HOME\install\portlist.ini file.
Note:
Theportlist.ini file if not updated if you change a port number after you install Oracle Database. "Changing the iSQL*Plus Ports" explains how to find the iSQL*Plus port number in this situationIn the Login window, enter the user name, password, and for the connect identifier, the name of the database to which you want to connect.

Passwords for all Oracle system administration accounts except SYS, SYSTEM, SYSMAN, and DBSNMP are revoked after installation. Before you use a locked account, you must unlock it and reset its password. If you created a starter database during the installation, Oracle Database Configuration Assistant displays a screen with your database information and the Password Management button. Use the Password Management button to unlock only the user names you will use.
If you created a starter database during the installation, but you did not unlock the required account, unlock the account using one of the following methods:
Note:
To permit unauthenticated access to your data through HTTP, unlock theANONYMOUS account.See Also:
Oracle Database Administrator's Guide for more information about:Unlocking and changing passwords after installation
Oracle security procedures
Security best practices
Use SQL*Plus to unlock accounts and change passwords any time after the installation process.
To change a password after installation:
Start SQL*Plus:
c:\> sqlplus /NOLOG
Connect as SYSDBA:
SQL> connect sys/SYS_password as sysdba
Enter a command similar to the following, where account is the user account that you want to unlock and password is the new password:
SQL> ALTER USER account [IDENTIFIED BY password] ACCOUNT UNLOCK;
In this example:
The ACCOUNT UNLOCK clause unlocks the account.
The IDENTIFIED BY password clause resets the password.
To unlock and reset user account passwords with Oracle Enterprise Manager 10g Database:
Log in to Database Control.
Click Administration.
In the Security section of the Administration page, click Users.
Enterprise Manager displays a table containing all database accounts. The Account Status column indicates whether the account is locked and whether the password is expired.
Select the user account you want to modify, then click Edit.
Use the General page of the Users property sheet to change the password and lock or unlock the selected account. Click Help for additional information.
The Oracle Database 10g software identifies a database by its global database name. A global database name consists of the database name and database domain. Usually, the database domain is the same as the network domain, but it need not be. The global database name uniquely distinguishes a database from any other database in the same network. You specify the global database name when you create a database during the installation, or when using Oracle Database Configuration Assistant. For example:
sales.us.mycompany.com
In this example:
sales is the name of the database. The database name portion is a string of no more than 30 characters that can contain alphanumeric, underscore (_), dollar ($), and pound (#) characters. The DB_NAME initialization parameter specifies the database name.
us.mycompany.com is the network domain in which the database is located. Together, the database name and the network domain make the global database name unique. The domain portion is a string of no more than 128 characters that can contain alphanumeric, underscore (_), and pound (#) characters. The DB_DOMAIN initialization parameter specifies the domain name.
The DB_NAME parameter and the DB_DOMAIN name parameter combine to create the global database name value assigned to the SERVICE_NAMES parameter in the initialization parameter file.
The system identifier (SID) identifies a specific database instance. The SID uniquely distinguishes the instance from any other instance on the same computer. Each database instance requires a unique SID and database name.
For example, if the SID and database name for an Oracle database are ORCL, then each database file is located in the ORACLE_BASE\ORACLE_HOME\orcl directory, and the initialization parameter file is located in the ORACLE_BASE\admin\orcl\pfile directory.
The starter database contains one database initialization parameter file. The initialization parameter file, init.ora.xxxxx, must exist for an instance to start. A parameter file is a text file that contains a list of instance configuration parameters. The starter database init.ora file has preconfigured parameters. You do not need to edit this file to use the starter database.
The server parameter file (SPFILE) is created from the initialization parameter file, then the initialization parameter file is renamed. The SPFILE file name is spfileSID.ora and is located in the ORACLE_BASE\ORACLE_HOME\database directory.
You can use Oracle Enterprise Manager Database Control to view the location of the server parameter file and list all of the initialization parameters, as follows:
Log in to Database Control.
Click Administration.
In the Instance section of the Administration page, click All Initialization Parameters.
Database Control displays a table listing the current value of each initialization parameter.
Click SPFile.
Database Control displays a table listing the value of each initialization parameter specified in the server parameter file. The location of the server parameter file is displayed before the table.

An Oracle Database is divided into smaller logical areas of space known as tablespaces. Each tablespace corresponds to one or more physical data files. Data files contain the contents of logical database structures such as tables and indexes. A data file can be associated with only one tablespace and database.
Note:
TheSYSAUX and SYSTEM tablespaces must be present in all Oracle Database 10g release 2 (10.2) databases.Table 5-2 list the tablespaces and data files in the Oracle Database. By default, the data files are located in the ORACLE_BASE\oradata\DB_NAME directory.
Table 5-2 Tablespaces and Data Files
| Tablespace | Data File | Description |

To use Oracle Enterprise Manager 10g Database to view the list of tablespaces currently available in your database:
Log in to Database Control.
Click Administration.
In the Storage section of the Administration page, click Tablespaces.
Enterprise Manager displays a table containing all the tablespaces currently defined for this database instance. For more information about using Database Control to view, modify, and create tablespaces, click Help.

"Managing the Undo Tablespace" of Oracle Database Administrator's Guide
A redo log can be either an online redo log or an archived redo log. The online redo log is a set of two or more redo log groups that records all changes made to Oracle data files and control files. An archived redo log is a copy of an online redo log that has been copied to an offline destination. If the database is in ARCHIVELOG mode and automatic archiving is enabled, then the archive process or processes copy each online redo log to one or more archive log destinations after it is filled.
The starter database and the custom database each contain three redo log files located in the ORACLE_BASE\oradata\DB_NAME directory. Redo log files hold a record of all changes made to data in the database buffer cache. If an instance fails, then Oracle Database uses the redo log files to recover the modified data in memory.
To use Oracle Enterprise Manager 10g Database to view or modify the redo log files for your starter database:
Start your Web browser and log in to Database Control.
Click Administration.
In the Storage section of the Administration page, click Redo Log Groups.
Enterprise Manager displays a table containing the control files currently defined for this database instance.
To view the name and location of the redo log file associated with a particular group, select that group then click View.
For more information about using Database Control to view, modify, and create tablespaces, click Help.

The starter database and the custom database contain three control files located in the ORACLE_BASE\oradata\DB_NAME directory. Oracle recommends that you keep at least three control files (on separate physical drives) for each database, and set the CONTROL_FILES initialization parameter to list each control file.
A control file is an administrative file required to start and run the database. The control file records the physical structure of the database. For example, a control file contains the database name, and the names and locations of the database data files and redo log files.
To use Oracle Enterprise Manager 10g Database to view or modify the control files for your starter database:
Log in to Database Control.
Click Administration.
In the Storage section of the Administration page, click Controlfiles.
Enterprise Manager displays a table containing the control files currently defined for this database instance. For more information about using control files and backing up control files, click Help.
See Also:
"Managing Control Files" of Oracle Database Administrator's Guide for information about setting this initialization parameter valueTwo main Oracle services are automatically started after installation when you create a database:
OracleServiceSID (Oracle Database service)
OracleHOME_NAMETNSListener (Oracle Database listener service)
If you installed Oracle Enterprise Manager Database Control, then the OracleDBConsoleSID service is automatically started. In you configured Automatic Storage Management, the OracleCSService and OracleASMService+ASM services are listed as well. However, other services for networking or other individual components may not automatically start.
