Ensuring a successful Cognos Business Intelligence server connection in a high availability environment

In a high availability environment, you must have at least one event processor (EP) installed with the Cognos® Business Intelligence server.

About this task

Important: Before you reinstall or upgrade IBM® Control Center to V6.1 or run configCC again, back up the cogstartup.xml file for each EP. If you do not back up the cogstartup.xml file, then the file is overwritten. If you have EPs that do not have the Cognos Business Intelligence server, then you must ensure a successful server connection or you can receive connection errors in your environment. For more information, see Troubleshooting Cognos Business Intelligence server.

To ensure a successful Cognos Business Intelligence server connection in a high availability environment:

Procedure

Stop your EP.
Go to the <Installation directory of your EP>/Cognos/configuration folder.
Open cogstartup.xml
Go to the element <crn:parameter name="internalDispatcher"> and set the child value the same as the <crn:parameter name="externalDispatcher"> element, including the port number.
Go to the element <crn:parameter name=contentManagers" opaque="true">.

Add all of the Cognos Business Intelligence server instance URLs to the child element <crn:value xsi:type="cfg:array">. The URLs must be in the same order on each of the Cognos Business Intelligence servers. Before you add the other URLs, the cogstartup.xml might appear like the following example:

<crn:parameter name="contentManagers" opaque="true">
           <crn:value xsi:type="cfg:array">
            <crn:item xsi:type="xsd:anyURI">URL:port number/p2pd/servlet</crn:item>
           </crn:value>
         </crn:parameter>

After you add the other URLs, the cogstartup.xml might appear like the following example:

<crn:parameter name="contentManagers" opaque="true">
           <crn:value xsi:type="cfg:array">
            <crn:item xsi:type="xsd:anyURI">URL:port number/p2pd/servlet</crn:item>
            <crn:item xsi:type="xsd:anyURI">URL:port number/p2pd/servlet</crn:item>
           </crn:value>
         </crn:parameter>

Restart your EP. Ensure that you start your EPs in the exact same order as they are listed in the cogstartup.xml file. Start the second EP only after the Cognos Business Intelligence server on the first EP is successfully started.

What to do next

Complete the same steps for the rest of your EPs in your environment.
