Refer the initiating bug in SailFin
"I am unable to create Connector Connection Pool using SailFin admin gui, when
Connector Module is deployed only on cluster.Steps to reproduce
1) Deploy the connector module on Cluster (it should be deployed only on
cluster not on DAS).
2) Try creating the Connector Connection Pool using admin gui. It will throw
some wierd errors on gui.
Please note that this works if you deploy using asadmin command. Also this
problem cannot be replicated if Connector Module is deployed on DAS and cluster
both. It should be deployed only on cluster to replicate this problem."
Enable the resource-adapter (connector) for DAS and create the pool. Once the
pool is created, disable connector and pool for DAS.
