1. On the OMS host, create a directory to store the logo image file to be used on the EM login page. For example, /u01/oracle/gc_inst/em/EMGC_OMS1/temp

2. Copy the logo image file to the newly created directory. For example, /u01/oracle/gc_inst/em/EMGC_OMS1/temp/custom_logo.png

3. In the newly created directory, create a WEB-INF directory. For example, /u01/oracle/gc_inst/em/EMGC_OMS1/temp/WEB-INF

4. In the WEB-INF directory create a file called web.xml with the following content:

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE web-app PUBLIC
   "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
   "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">
   <web-app>
   </web-app>

5. Login to the Weblogic console. Username by default is weblogic and password is the sysman password.

   URL: https://hostname:port/console

   Example: https://<fully_qualified_host_name>:7102/console

   Note:

   The Weblogic console URL (Admin Server URL) is not the same URL as the Enterprise Manager console. The host and the port are values specified in the AS_HOST and AS_HTTPS_PORT parameters, respectively, in the emgc.properties file. This properties file is available in the Oracle Management Service Instance Base location of the first OMS. For example, /u01/oracle/gc_inst/em/EMGC_OMS1/emgc.properties. The Admin Server URL can also be found in the <EM Home Dir>/install/setupinfo.txt file.

6. Enable ‘http’ port for the Admin Server. This can be done from the Admin Server settings.

   1. From the tree view, expand Environment and then select Servers. Find and click EMGC_ADMINSERVER (admin) in the table.

      Note:

      For multi-OMS deployments, the custom logo image can be hosted on each OMS server. In case an OMS server is not available due to patching or upgrade, the running OMS server can still access the logo image hosted by its own OMS tier. To configure the logo image in this method, deploy the image to each OMS tier, for example, EMGC_OMS1, EMGC_OMS2, EMGC_OMS3 and so on, instead of EMGC_ADMINSERVER.

   2. Settings for EMGC_ADMINSERVER page opens. Go to the General Tab, if not opened already. Select the Listen Port Enabled check box.

   3. Edit the port number as required. The default port number is 7001. The value of Listen Port will be the http port which will be used later to run the emctl command to set the image file.

   4. Click Save. The following message appears at the top of the screen:

      All changes have been activated. No restarts are necessary.

      Settings updated successfully.

7. Click Deployments menu at the left. The Install button is disabled by default.

8. Click Lock & Edit to enable the Install button.

9. In the Deployments screen, click the Install button.

10. Set the path to the directory created from Step 1 ( /u01/oracle/gc_inst/em/EMGC_OMS1/temp).

11. Click Next.

12. In the next screen, accept the default values for the selected options. By default Install this deployment as an application option will be selected.

13. Click Next.

14. In the next screen, select EMGC_ADMINSERVER as the target.

15. Click Next.

16. In the next screen, accept the default values.

17. Click Finish.

    If the application is successfully deployed, the following message appears:

    All changes have been activated. No restarts are necessary.

    The deployment has been successfully installed.

18. Ensure that the status of the web application 'temp' deployed above is in 'Active' state. If not, click Activate Changes on the upper left corner to activate.

19. If the status of ‘temp’ appears as Prepared even after Step 18, select ‘temp’ from the table and click Start.

    Note:

    Ensure that the status of ‘temp’ appears ‘Active’ in the Deployments table.

20. Access the file path to ensure the image appears on the browser screen.

    URL: http://hostname:port/console/<newly created directory>/<logo image filename>

    Example: http://<fully_qualified_host_name>:7001/temp/custom_logo.png

    Both http and https based image location are supported.
