Configuring Enterprise User Security for an Oracle database primarily involves creating directory objects to store enterprise user and database information. For some implementations, it can also require creating special network configuration files (ldap.ora
) that enable your databases to locate the correct directory server on the network.
While Oracle Enterprise Manager is your primary tool for both configuring Enterprise User Security and for administration tasks, this chapter introduces all the available tools, in the following topics:
Enterprise users are database users whose identities are stored and centrally managed in an LDAP directory, such as Oracle Internet Directory. Table 3-1 provides a summary of Enterprise User Security configuration and management tasks and the tools to complete them. The tool names are links to sections that describe them.

Oracle Internet Directory Self-Service Console is a tool based on Delegated Administration Services. This is a self service application that allows administrated access to the applications data managed in the directory. This tool comes ready to use with Oracle Internet Directory.
The Oracle Identity Management Guide to Delegated Administration discusses Delegated Administration Services and the Oracle Internet Directory Self-Service Console tool.
Oracle Net Configuration Assistant is a wizard-based tool with a graphical user interface. Its primary uses are to configure basic Oracle Net network components, such as listener names and protocol addresses, and to configure your Oracle home for directory server usage. The latter use is what makes this tool important for configuring Enterprise User Security.
If you use Domain Name System (DNS) discovery (automatic domain name lookup) to locate Oracle Internet Directory on your network, then this assistant is not necessary. Note that using DNS discovery is the recommended configuration. See Oracle Internet Directory Administrator's Guide for information about this configuration.
Before you can register a database with the directory, you must do either one of the following two tasks:
Configure DNS discovery of Oracle Internet Directory on your network.
See Also:
Oracle Internet Directory Administrator's Guide for information about DNS server discoveryIf DNS discovery is not configured on your network, then use Oracle Net Configuration Assistant to create an ldap.ora
file for your Oracle home.
Your database initially uses the ldap.ora
file to locate the correct Oracle Internet Directory server on your network. This configuration file contains the hostname, port number, and identity management realm information for your directory server.
Once database registration is complete, the realm is ascertained through the database DN stored in the database wallet.
To start Oracle Net Configuration Assistant:
(UNIX) From $ORACLE_HOME
/bin
, enter the following at the command line:
netca
(Windows) Choose Start, Programs, Oracle-HOME_NAME, Configuration and Migration Tools, Net Configuration Assistant
After you start this tool, you will be presented with the opening page shown in Figure 3-1.
Choose the Directory Usage Configuration option on this page, click Next, and choose the directory server where you wish to store your enterprise users. Then, click Finish to create a properly configured ldap.ora
file for your Oracle home.

Database Configuration Assistant is a wizard-based tool used to create and configure Oracle databases.
Use Database Configuration Assistant to register a database with the directory. In that process, Database Configuration Assistant creates a distinguished name (DN) for the database and the corresponding entry and subtree in Oracle Internet Directory.
To start Database Configuration Assistant:
(UNIX) From $ORACLE_HOME
/bin
, enter dbca
at the command line:
(Windows) Choose Start > Programs > Oracle - HOME_NAME > Configuration and Migration Tools > Database Configuration Assistant

Security administrators use Oracle Wallet Manager to manage public key security credentials on Oracle clients and servers. The wallets it creates can be read by Oracle Database, Oracle Application Server 10g, and the Oracle Identity Management infrastructure.
To start Oracle Wallet Manager:
(Windows) Select Start, Programs, Oracle-HOME_NAME, Integrated Management Tools, Wallet Manager
(UNIX) At the command line, enter owm
.
The orapki
command line utility enables administrators to manage wallets, certificate revocation lists, and other public key infrastructure (PKI) elements from the command line. It can be used inside scripts, enabling administrators to automate many routine PKI tasks. The orapki
commands enable you to do the following tasks:
Enterprise User Security employs Oracle Enterprise Manager to administer enterprise users, administrative groups, enterprise domains, and enterprise roles stored in Oracle Internet Directory. You can use the Web-based user interface provided by Enterprise Manager Database Control or Enterprise Manager Grid Control to administer Enterprise User Security.
Enterprise users are users provisioned and managed centrally in an LDAP-compliant directory, such as Oracle Internet Directory, for database access. Enterprise domains are directory constructs containing databases, enterprise roles (the access privileges assigned to enterprise users), and proxy permissions (which enable enterprise users to connect to databases as other users).

Chapter 1, "Introducing Enterprise User Security" for a discussion of Enterprise User Security administrative groups, enterprise domains, enterprise roles, enterprise users, shared schemas, and user-schema mappingsUse the following steps to access the Enterprise User Security link in Oracle Enterprise Manager Database Control or Grid Control:
Enter the URL for Database Control or Grid Control in a browser window. For example:
https://mydbhost:1158/em
Log in as an administrative database user.
Click the Server tab. Under the Security section, click Enterprise User Security.
Note:
If you are using Enterprise Manager Grid Control, then you would need to navigate to the target database page before you can access the Server tab for the database.The Oracle Internet Directory Login page appears.
Enter the distinguished name (DN) of a directory user, who has administrative privileges for the identity management realm, in the User field. Enter the user password in the Password field. Click Login.
The Enterprise User Security page appears.
User Migration Utility is a command-line tool that enables you to perform bulk migrations of database users to Oracle Internet Directory where they are stored and managed as enterprise users. This tool performs a bulk migration in two phases: In phase one, it populates a table with database user information. During phase two, the database user information is migrated to the directory.
This tool is automatically installed in the following location when you install an Oracle Database client:
$ORACLE_HOME/rdbms/bin/umu
The basic syntax for this utility is as follows:
umu parameter_keyword_1=value1:value2
parameter_keyword_2=value parameter_keyword_3=value1:value2:value3 ... parameter_keyword_n=value
Note that when a parameter takes multiple values, they are separated with colons (:).
