PH02608: CICS API TRANSFORM DATATOJSON COMMAND REMOVES ACCESS TO CURRENT CHANNEL DFHAHC-V1

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In a CICS Web Service, an EXEC CICS TRANSFORM DATATOJSON is
  issued with CHANNEL('DatatoJson'). After the command, the
  CURRENT channel is changed to datatojson which effectively
  removes access to DFHAHC-V1.
  Without access to Channel DFHAHC-V1 the application logic can't
  access web service containers and therefore can't send a
  response.
  

Local fix

• Remove EXEC CICS TRANSFORM DATATOJSON command.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: The current CHANNEL at a LINK level     *
  *                      program is changed by an EXEC CICS      *
  *                      TRANSFORM DATATOJSON command.           *
  ****************************************************************
  A WEB Service application provider is LINKed to with CHANNEL
  DFHAHC-V1.
  A new user CHANNEL is created followed by an EXEC CICS
  TRANSFORM DATATOJSON passing the new CHANNEL in the CHANNEL
  parameter.
  During the data transformation the current CHANNEL is changed
  to the new CHANNEL, making CHANNEL DFHAHC-V1 inaccessible at
  that LINK level.
  

Problem conclusion

• DFHEIML and DFHMLJS have been changed to prevent the current
  CHANNEL being changed by an EXEC CICS TRANSFORM DATATOJSON
  or JSONTODATA command.
