DDS nodes display in Joining status and Campaigns do not run

SA-88049

Summary



After installing WebLogic Security patch implementing JEP 290, the Decision Data Store (DDS) nodes display in the Joining status in Pega Designer Studio Decisioning Infrastructure landing page. As a result, Campaigns do not execute.


Error Messages



Message in the WebLogic Server logs:

<Info> <java.io.serialization> <localhost.localdomain> <DDSServer_1> <DSM init service: DDS.Default> <<anonymous>> <> <6870ae16-8236-45ad-8e88-bdf93b703a50-00000014> <1567007075984> <[severity-value: 64] [rid: 0:42:4] [partition-id: 0] [partition-name: DOMAIN] > <BEA-000000> <ObjectInputFilter REJECTED: class java.rmi.server.RemoteObject, array length: -1, nRefs: 6, depth: 3, bytes: 169, ex: n/a>


Steps to Reproduce

  1. Install WebLogic Security patch.
  2. Restart all the nodes.


Root Cause



A third-party product issue.
The Application server Security patch contains the implementation of the JDK Enhancement Proposal JEP 290: Filter Incoming Serialization Data blocking JMX local traffic on Cassandra port (default port is 7199). Therefore, the Pega Engine is unable to determine the Cassandra Run status.



Resolution



Make the following change to the operating environment:

Include the below arguments to the Application server Start JVM options:


-Dweblogic.oif.serialFilterMode=combine
-Dweblogic.oif.serialFilter=java.rmi.server.RemoteObject
