IBM CICS Resource adapter downgrades from XA to LocalTransaction datasource in JBoss

Solution In Progress - Updated -

Environment

  • Red Hat JBoss Enterprise Application Platform 6.3.3
  • IBM CICS 7.5.0.4-p750-004-140807

Issue

  • An XA capable resource adapter is treated as a local transaction datasource as evidenced by
WARN  [com.arjuna.ats.arjuna] (default-threads - 46) ARJUNA012140: Adding multiple last resources is disallowed. Trying to add LastResourceRecord(XAOnePhaseResource(LocalXAResourceImpl@<#>[connectionListener=<#> connectionManager=<#> warned=false currentXid=< formatId=<id>, gtrid_length=<n>, bqual_length=<n>, tx_uid=<tx_id>, node_name=1, branch_uid=<branch id>, subordinatenodename=null, eis_name=java:/jdbc/<ds name> > productName=<product> productVersion=<version> jndiName=java:/jdbc/<jndi name>])), but already have LastResourceRecord(XAOnePhaseResource(LocalXAResourceImpl@<#>[connectionListener=<#> connectionManager=<#> warned=false currentXid=< formatId=<#>, gtrid_length=<#>, bqual_length=<#>, tx_uid=<tx id>, node_name=1, branch_uid=<branch id>, subordinatenodename=null, eis_name=java:/eis/<name> > productName=<product> productVersion=unknown jndiName=java:/eis/<jndi name]))

Resolution

The config-property <config-property name="xaSupport">off</config-property> should be over-ridden in the deployment descriptor (using on). Notice that by default it is off:
