C Postinstallation Oracle Database Vault Procedures

Deploying Database Vault Administrator to a Standalone OC4J Container

You can manually deploy Database Vault Administrator to the Oracle Application Server Containers for J2EE (OC4J) home, which by default is in the $ORACLE_HOME/oc4j/j2ee/home directory.

To manually deploy Database Vault Administrator:

1. Edit the file $ORACLE_HOME/oc4j/j2ee/home/config/server.xml. Enter the following line just before the last line that reads, </application-server>:

   <application name="dva" path="Oracle_home_dir/dv/jlib/dva_webapp.ear" auto-start="true" />
   

   Replace Oracle_home_dir with the relative or direct path to the Oracle home directory. (You cannot enter the $ORACLE_HOME environment variable.)

   For example:

   <application name="dva" path="/u00/app/oracle/oracle/product/dv12/dv/jlib/dva_webapp.ear" auto-start="true" />
   

2. Edit the file $ORACLE_HOME/oc4j/j2ee/home/config/http-web-site.xml. Enter the following line just above the last line that reads, </web-site>:

   <web-app application="dva" name="dva_webapp" root="/dva" />
   

3. Edit the file $ORACLE_HOME/oc4j/j2ee/home/config/global-web-application.xml. Search for <servlet-class>oracle.jsp.runtimev2.JspServlet</servlet-class>. Uncomment the following lines after this:

   <init-param>
      <param-name>main_mode</param-name>
      <param-value>justrun</param-value>
   </init-param>
   

4. Create the following directory:

   mkdir -p $ORACLE_HOME/dv/jlib/sysman/config
   

5. Create the database connection configuration file, emoms.properties, in the configuration directory that you just created. Add the following lines to the file:

   oracle.sysman.emSDK.svlt.ConsoleMode=standalone
   oracle.sysman.eml.mntr.emdRepRAC=FALSE
   oracle.sysman.eml.mntr.emdRepDBName=oracle_sid
   oracle.system.eml.mntr.emdRepConnectDescriptor=TNS_connection_string
   

   Follow these instructions:

   • For an Oracle RAC environment, set oracle.sysman.eml.mntr.emdRepRAC to TRUE.

   • For oracle.sysman.eml.mntr.emdRepConnectDescriptor, you can use an alias from $ORACLE_HOME/network/admin/tnsnames.ora. Alternatively, you can use the following syntax:

     oracle.sysman.eml.mntr.emdRepConnectDescriptor=
       (DESCRIPTION\=
         (ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP) (HOST\=HOSTNAME)(PORT\=PORT))) 
         (CONNECT_DATA\=
            (SERVICE_NAME\=ORACLE_SID))
     

6. Ensure that the correct environment variables are set.

   For example:

   ORACLE_SID=orcl
   export ORACLE_SID
   ORACLE_HOME=/u00/app/oracle/product/11.2
   export ORACLE_HOME
   LD_LIBRARY_PATH=$ORACLE_HOME/bin:$ORACLE_HOME/lib:$ORACLE_HOME/jdbc/lib
   export LD_LIBRARY_PATH
   PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH
   export PATH
   

   Set the LD_LIBRARY_PATH variable to use the OCI-based JDBC libraries.

7. Start OC4J using the following syntax:

   $ORACLE_HOME/jdk/bin/java -Djava.awt.headless=true -DEMDROOT=$ORACLE_HOME/dv/jlib -jar $ORACLE_HOME/oc4j/j2ee/home/oc4j.jar -userThreads -config $ORACLE_HOME/oc4j/j2ee/home/config/server.xml
   

After you complete these steps, you can start Database Vault Administrator. The HTTP port defaults to 8888 for this environment. Use the following syntax for the URL:

http://hostname:8888/dva

Deploying Database Vault Administrator to the Database Console OC4J Container

To manually deploy Database Vault Administrator to the Database Console OC4J container:

1. Stop Oracle Database Console.

   • UNIX: Go to the $ORACLE_HOME/bin directory and run the following command:

     ./emctl stop dbconsole
     

   • Windows: In the Administrative Services, select the Services utility, and then right-click the OracleDBConsolesid service. Select Stop from the menu.

2. Create a backup copy and then open the $ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_service_name/config/server.xml file.

3. Add the following line before the </application-server> element:

   <application name="dva" path="$ORACLE_HOME/dv/jlib/dva_webapp.ear" parent="default" start="true" />
   

   On Windows systems, replace $ORACLE_HOME with the absolute path to your Oracle Database home.

4. Create a backup copy and then open the $ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_service_name/config/http-web-site.xml file.

5. Add the following line before the </web-site> element:

   <web-app application="dva" name="dva_webapp" load-on-startup="true" root="/dva" shared="true"/>
   

6. Restart Oracle Database Console.

   • UNIX: Go to the $ORACLE_HOME/bin directory and run the following command:

     ./emctl start dbconsole
     

   • Windows: In the Administrative Services, select the Services utility, and then right-click the OracleDBConsolesid service. Select Start from the menu.

After you complete these steps, you can start Oracle Database Vault Administrator by using the following URL:

https://hostname:port/dva

For example:

https://myserver:1158/dva

If you are unsure of the port number, open the ORACLE_HOME/host_sid/sysman/config/emd.properties file and search for REPOSITORY_URL. In most cases, the host name and port number are the same as Oracle Enterprise Manager Database Control.

Enabling Oracle Database Vault Administrator Accessibility Mode

Oracle Database Vault Administrator takes advantage of user interface development technologies that improve the responsiveness of some user operations. For example, when you navigate to a new record set in a table, Oracle Database Vault Administrator does not redisplay the entire HTML page. However, this performance-improving technology is generally not supported by screen readers. To disable this feature, and as a result, make the Database Vault Administrator HTML pages more accessible for disabled users, use the following procedure.

To enable the display of an entire HTML page:

1. Locate the uix-config.xml configuration file.

   By default, the uix-config.xml file is in the following directory:

   $ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/em/em/WEB-INF 
   

2. Open the uix-config.xml file using a text editor and locate the following entry:

   <!-- An alternate configuration that disables accessibility features  -->
   <default-configuration>
     <accessibility-mode>inaccessible</accessibility-mode>
   ...
   </default-configuration>
   

3. Change the value of the accessibility-mode property from inaccessible to accessible.

4. Save and close the uix-config.xml file.

5. Restart Database Vault Administrator.

   See "Starting Oracle Database Vault".

Providing Textual Descriptions of Database Vault Administrator Charts

The Monitor page of Database Vault Administrator displays security policy data in a chart. However, charts do not convey information in a manner that can be read by a screen reader. To remedy this problem, you can configure Database Vault Administrator to provide a complete textual representation of each chart. By default, support for the textual representation of charts is disabled. When textual description for charts is enabled, Database Vault Administrator displays a textual representation of the chart data.

To enable the textual representation of charts:

1. Locate the web.xml configuration file.

   To locate the web.xml file in a Oracle Database 10g installation, change directory to the following location in the Oracle home:

   $ORACLE_HOME/dv/jlib/dva_webapp/dva_webapp/WEB-INF/
   

2. Open the web.xml file with your favorite text editor and locate the following six lines of the file:

   <!-- Uncomment this to enable textual chart descriptions
   <context-param>
   <param-name>enableChartDescription</param-name>
   <param-value>true</param-value>
   </context-param>
   -->
   

3. Remove comments from this section by deleting the first line and the last line of this section so that the section consists of only these four lines:

   <context-param>
   <param-name>enableChartDescription</param-name>
   <param-value>true</param-value>
   </context-param>
   

4. Save and exit the web.xml file.

5. Restart Database Vault Administrator.
