Resetting a lost oc4jadmin password

A common question is how do I change the oc4jadmin password when I don't already know it? If you have access to the application owner's UNIX account its quite easy. But note that it does require a restart of the 10g application server. Since you've lost the password I'm hoping that you're on a development system, so restarting the application server shouldn't be a big deal for you.

1. Start by locating the correct Oracle home, let's assume that it's .../10gas/10.1.3 for our example
2. Do a quick check to see that it has the "home" OC4J instance running in it as shown here

   oracle@myhost > /oracle/10gas/10.1.3/opmn/bin/opmnctl status
   
   Processes in Instance: demo.myhost
   ---------------------------------+--------------------+---------+---------
   ias-component                    | process-type       |     pid | status
   ---------------------------------+--------------------+---------+---------
   OC4JGroup:default_group          | OC4J:bixmlpserver  |   17003 | Alive
   OC4JGroup:default_group          | OC4J:bianalytics   |   17002 | Alive
   OC4JGroup:default_group          | OC4J:bijmx         |   17001 | Alive
   OC4JGroup:default_group          | OC4J:home          |   17000 | Alive
   ASG                              | ASG                |     N/A | Down
   HTTP_Server                      | HTTP_Server        |   16999 | Alive

   
   
3. Now edit the .../10gas/10.1.3/j2ee/home/config/system-jazn-data.xml
4. Search for the keyword "oc4jadmin" to locate the following stanza:
   

       <user>
        <name>oc4jadmin</name>
        <display-name>OC4J Administrator</display-name>
        <guid>4FE81440BD2911DBBF8EED2D8B2D4B8C</guid>
        <description>OC4J Administrator</description>
           <credentials>{903}YD4N1akwPa8FxfnwvqTAT76FCx62bGsfU8Kzd2p+IJQ=</credentials>
    </user>
   

   
   
5. Change the content of the credentials tag to something like this:
   

   <credentials>!mynewpassword</credentials>
   

   Note the exclamation mark at the beginning of the new password. It marks the entry as a non-encrypted password value.
   
6. Save the file


7. Use .../10gas/10.1.3/opmn/bin/opmnctl to restart the OC4J apps server


8. Login to the applications server as the oc4jadmin user to verify that your new password works
   
9. If you check the system-jazn-data.xml file after the restart you should see that your edit has been replaced by an encrypted version of the password
