The Oracle Internet Directory (OID) is an LDAP v3 compliant directory that is used to look up information. The Single Sign-On application uses OID to authenticate users for example. OID places information into Realms and this screen is asking you to define a default Realm for OID to store users, groups and policies. Recommend that you accept the suggested name space unless you wish to specify a namespace for your organization such as dc=mycompany,dc=com. Click Next to proceed to the Database Identification screen, as seen in Figure 3-9.

The Database Identification screen defines the SID and Global Database Name for the OracleAS Metadata Repository database. The requirements for these items are the same as any Oracle database. The SID is a unique name for the database. The default (which is used in the example) is “asdb”. In prior releases it defaulted to “iasdb”. The Global Database Name is normally the SID followed by the server’s domain name. In the example I used asdb.proxitec.com however some of the examples in this book used iasdb.localdomain.com. The Global Database Name is not an address but the full name of the database instance. It is used in connecting to the database and with database links. Recommend that you use asdb with your own domain name. Select next to continue to set the sys and system passwords.
This screen allows you to set the SYS and SYSTEM passwords for the Metadata Repository database. Note that the passwords must meet minimum requirements, containing both letters and numbers. Write them down! There are a lot of passwords in Oracle Application Server 10g. Click Next to proceed to the Database File Location screen, shown in Figure 3-10.
