Additional Changes in OBPM deployment (.ear)
- Open the OBPM deployment (ear) and navigate to PMEJB.jar file. Open PMEJB.jar file and navigate to META-INF folder. You will find ejb-jar.xml file. Modify this file by adding following additional tags.
  <message-driven> <ejb-name>CacheEvictTopicMDBBean</ejb-name> <activation-config> <activation-config-property> <activation-config-property-name>topicMessagesDistributionMode</activation-config-property-name> <activation-config-property-value>One-Copy-Per-Server</activation-config-property-value> </activation-config-property> <activation-config-property> <activation-config-property-name>distributedDestinationConnection</activation-config-property-name> <activation-config-property-value>EveryMember</activation-config-property-value> </activation-config-property> </activation-config> </message-driven>
  
  Sample file attach for reference. Note ejb-jar.xml file already contain few configurations with respect to MultiEntityManagerWrapper, please do not remove the same.
- Since PMEJB.jar is getting reference in few additional jar and war present in OBPM deployment, Also, modify those files by adding ejb-jar.xml. Below is list of additional files from deployment and their respective folder where we need to copy ejb-jar.xml.
  
  Please note, this ejb-jar.xml will be different than attached in point number 1. Use one attach given below for reference.
