Error description

• They receive DFHII0209 - unable to parse a request header,
  and DFHAC2236 for transaction CIRR and abend AII2 in program
  DFHIIRRS term ????.
     The problem is in the way that CICS parses a GIOP request
  looking for service context information. The GIOP request has
  a field saying how many service contexts there are and then
  following this are the service contexts themselves. Each service
  context has a fullword id and length followed by the data. Each
  service context is aligned on a fullword boundary. CICS looks at
  each service context in turn bumping on the pointer to the next.
  If at the end of processing the service requests the pointer is
  past the end of the buffer holding the GIOP request, the
  service_context_error is raised and CICS bypasses further
  processing (including setting the asserted id).
  The problem in this case is that the last service context in
  the buffer only has two bytes of data. When we bump the pointer
  to the next full-word boundary we now are past the end of the
  buffer.
     Trace entry =002066= in TAPR.PMR13218.B031C724.CICSTRAC.FULL
  shows the buffer we are processing. There are 6 service contexts
  starting at X'90'. The buffer is X'84A' bytes long. The last
  service context is at +X'840'. After processing the following
  algorithm is used to bump the pointer.
  msg_ptr=msg_ptr+offset(contextData)+(((context_length+3)/4)*4);
  So, msg_ptr=X'840'+X'8'+(((2+3)/4)*4) which gives a grand total
  of X'84C' (pointing past the end of the buffer).
  The problem is in iirh_set_service_context_ptrs. We need to add
  code to handle the case when the last service context has less
  than 4 bytes of data.

  ****************************************************************
  An attempt to invoke an EJB deployed in a CICS CORBASERVER fails
  with message DFHII0209 and a transaction abend AII2. An
  exception trace entry II 0214 SERVICE_CONTEXT_ERROR is written.
  
  This failure occurs during parsing of the service contexts sent
  in a GIOP 1.2 request from a partner ORB. You may see this
  failure when you invoke a CICS EJB from an application installed
  in WebSphere Application Server for z/OS v5.1.

Problem conclusion

• DFHIIRH has been changed to correctly parse the service contexts
  in a GIOP 1.2 request.
