Unable to start a Business process <policy_name>.bsp policy

Problem:

Unable to start a Business process <policy_name>.bsp policy. All the links within the policy are greyed out.  (See figure 1 below.)

You may experience this issue if you're installing CEP for the first time, if you're deploying a second instance of CEP, or if the lax.nl.java.option.additional= line in your ATPNODE.lax file was edited after installation.

Solution:

1. Back up the file [AP_HOME]/localhost/ATPNODE.lax.
2. Use the Vi text editor to open ATPNODE.lax for editing.
3. Find this line:

    lax.nl.java.option.additional=

4. Add the following to the end of the line:

   -Djava.awt.headless=true

   If the line includes existing settings, insert the new text after them. For example, if yours includes -server, then specify:

   lax.nl.java.option.additional=-server -Djava.awt.headless=true

5. Save the file.
6. Restart the CEP Server (ATPNODE process). See the AutoPilot M6 Installation Guide for details.
7. Check the business process to verify whether the business process flow has started. It should look like figure 2 below.
