Symptoms

See EDR Generation issue when splitting a 4 node cluster (Server1, Server2, Server3, Server4) into two smaller clusters with 2 nodes each Server1 + Server2 and Server3 + Server4.


The splitting was done as follows:

Cluster1
Name: WLNG_Cluster
Nodes: IP_Server1:PORT_Server1, IP_Server2:PORT_Server2

Cluster2
Name:WLNG_Cluster_Second
Nodes: IP_Server3:PORT_Server3, IP_Server4:PORT_Server4

Both clusters belong to the same Coherence Cluster: WLNG_Coherence_Cluster

By Default the HA-Domain creates the JMS-modules:
WLNGEDRResource
WLNGJMSResource
WLNG_ATJMSResource

Added the corresponding modules for the new cluster:
Second_WLNGEDRResource
Second_WLNGJMSResource
Second_WLNG_ATJMSResource

The issue is that the EDRs are not generated for requests that reach Server3  and Server4 .
For each request to Server 3 or 4 the following error is observed:

Checking the JNDI tree of each server and it can be seen that for Server1 and Server2 the object com.bea.wlcp.wlng.edr.at.atEdrLog is present whereas for Server3 and Server4  it isn't.
