On the netca configuration pages, select the default
listener named LISTENER with a protocol of TCP and the default port number of 1521.
Database Credentials
In Figure A-4, you provide the initial passwords for the administrative user accounts. After the
installation, be sure to create at least one account with DBA privileges to use instead of SYS or
SYSTEM for day-to-day administrative tasks.
If you wish to use different passwords for the SYS, SYSTEM, DBSNMP, and SYSMAN accounts,
you can do that on this window; later in the installation, after the database has been created, you
will have the opportunity to change the passwords for all of the approximately 40 user accounts
created in a typical installation.

Storage Options
The database can use a number of different methods for storing datafiles, control files, and redo
log files. If you have the extra memory to dedicate another database instance for managing disk
space, choose ASM. An instance to manage ASM is fairly lightweight; typically, it will use no
more than 100MB of RAM, and only enough disk space for an SPFILE. If you are in a Real
Application Clusters environment and you don??™t have a cluster file system available (such as
OCFS), then choose Raw Devices.
