C Postinstallation Oracle Database Vault Procedures

Deploying Database Vault Administrator to a Standalone OC4J Container

You can manually deploy Database Vault Administrator to the following Oracle Application Server Containers for J2EE (OC4J) home:

Follow these steps 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/dv/jlib/dva_webapp.ear" auto-start="true" />
   

   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 special 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. Start OC4J. Before starting OC4J, ensure that the correct environment variables are set.

   For example:

   ORACLE_SID=orcl
   export ORACLE_SID
   ORACLE_HOME=/u00/app/oracle/product/11.2/dv
   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 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.

   See "Starting Oracle Database Vault".

Syntax for Using DVCA -action addlanguages

The syntax for using dvca -action addlanguages is as follows:

dvca -action addlanguages 
  -oh Oracle_home
  -instance Oracle_SID_name 
  -dbname database_name 
  -dbuniquename database_unique_name
  -sys_passwd SYS_password
  -dvsys_passwd DVSYS_password
  -jdbc_str jdbc_connection_string
  -languages language_list
  [-owner_account DV_owner_account_name]
  [-owner_passwd DV_owner_account_password]
  [-acctmgr_account DV_account_manager_account_name] 
  [-acctmgr_passwd DV_account_manager_password]
  [-silent] 
  [-logfile ./dvca.log] 
  [-nodecrypt]
  [-lockout] 
  [-racnode node]

In this specification:

• -action is the action to perform. In this case the action is addlanguages.

• -oh is the Oracle home for the Oracle RAC instance. Provide the ORACLE_HOME path.

• -instance is the name of the database instance. You can confirm this name by querying the INSTANCE_NAME column of the V$INSTANCE view. It specified in the entry for the database instance in the listener.ora file that is on the server.

• -dbname is the database identifier. You can confirm this name by querying the NAME column of the V$DATABASE data dictionary view.

• -dbuniquename is the globally unique name for the database.

• -sys_passwd is the password for the SYS user. If you enter a cleartext password on the command line, then you must include the nodecrypt option. If you omit the password, then DVCA prompts you for it. For better security, Oracle strongly recommends that you omit the password and then enter it interactively when you are prompted.

• -dvsys_passwd is the password for the DVSYS user. If you enter a cleartext password on the command line, then you must include the nodecrypt option. If you omit the password, then DVCA prompts you for it. Preferably, omit the password and then enter the password interactively when prompted.

• -jdbc_str is the JDBC connection string used to connect to the database. Enter the net service name (that is, the SID) as it is listed in the tnsnames.ora file, which is located in the $ORACLE_HOME/network/admin directory. For example:

  -jdbc_str jdbc:oracle:oci:@sales_orders
  

• -languages is the list of languages to be loaded. Provide the list of languages as a string in the following format:

  • UNIX: {"language_1,language_2,language_n"}

  • Windows: {"language_1","language_2","language_n"}

  Oracle Database Vault supports the following languages:

  	en: English	ja: Japanese
  	de: German	ko: Korean
  	es: Spanish	pt_BR: Brazilian Portuguese
  	fr: French	zh_CN: Simplified Chinese
  	it: Italian	zh_TW: Traditional Chinese

  
  

  For example, to load German and Spanish, you would enter the following:

  • UNIX: -languages {"de,es"}

  • Windows: -languages {"de","es"}

• -owner_account is the Oracle Database Vault Owner (DV_OWNER) account name.

• -owner_passwd is the Oracle Database Vault Owner account password. If you enter a cleartext password on the command line, then you must include the nodecrypt option. If you omit the password, then DVCA prompts you for it. Preferably, omit the password and then enter it interactively when prompted.

• -acctmgr_account is the Oracle Database Vault Account Manager (DV_ACCTMGR) user name.

• -acctmgr_passwd is the Oracle Database Vault Account Manager (DV_ACCTMGR) password. If you enter a cleartext password on the command line, then you must include the nodecrypt option. If you omit the password, then DVCA prompts you for it. Preferably, omit the password and then enter it interactively when prompted.

• -silent is the option to run in command line mode. This option is required if you are not running DVCA in an xterm window.

• -logfile is an optional flag to specify a log file name and location. You can enter an absolute path, or enter a path that is relative to the location of the $ORACLE_HOME/bin directory.

• -nodecrypt is the option to read plaintext passwords.

• -lockout is the flag used to disable SYSDBA operating system authentication. (This option is deprecated.)

• -racnode is the host name of the Oracle RAC node on which the action is being performed. Do not include the domain name with the host name.

After you enter the dvca -action addlanguages command and if you omit the passwords, you will be prompted for the passwords of the SYS, DVSYS, DV_OWNER, and DV_ACCTMGR users. For better security, enter the passwords interactively.

Procedure for Adding Languages to Oracle Database Vault

To add languages to Oracle Database Vault:

1. Log in to SQL*Plus as a user who has been granted the DV_OWNER role.

2. Temporarily grant the DV_PATCH_ADMIN role to the user responsible for adding languages (for example, user SYS).

   GRANT DV_PATCH_ADMIN TO SYS;
   

3. Notify this user to use DVCA to add the languages that are needed.

   For example:

   dvca -action addlanguages 
     -oh c:\oracle\product\11.2.0\db_1 
     -instance sales_orders
     -dbname sales_db
     -dbuniquename sales_db14
     -jdbc_str jdbc:oracle:oci:@sales_orders
     -owner_account dbvowner
     -acctmgr_account dbvacctmgr
     -languages {"es","ja"}
     -silent 
     -logfile dvcalog.txt 
   
   Enter SYS password: sys_password
   Enter DVSYS password: dvsys_password
   Enter owner password: owner_password
   Enter DV account manager password: dv_acct_password
   

4. Revoke the DV_PATCH_ADMIN role from user to whom you granted it in Step 2.

   REVOKE DV_PATCH_ADMIN FROM SYS;
