  No support for global transactions for IMS to WebSphere
  Application Server applications using WOLA even when running
  IMS with RRS=YES
  

Problem conclusion

• Support is added to WOLA to propagate and assert the RRS
  transaction context from IMS to WebSphere Application Server.
  The IMS application has to have called the WOLA Register API
  (BBOA1REG) and requested transactions support. The target WAS
  application server must have the environment variable
  'ola_rrs_context_propagate' defined and set to 1, or true. The
  IMS environment must be running with RRS=YES. With this, IMS
  to WebSphere Application Server global transactions are now
  supported.
  
  APAR PM63912 is currently targeted for inclusion in
  Fix Packs 8.0.0.4 and 8.5.0.1 of WebSphere Application
  Server.
