Customers affected: All Information Exchange customers using Expedite/CICS for MVS (OS/390 and z/OS platforms).

Note: The information in this technical bulletin should be read by all Expedite/CICS customers who plan to upgrade their present version of Expedite/CICS with the latest modification level.

This Technical Bulletin describes the modifications in Expedite/CICS. These modifications include the following:

• Recompilation of the original base product using Enterprise COBOL for z/OS V3R4, and CICS TS V2.2
• Elimination of the DUPREC condition
• Elimination of the "Invalid TCPIP port" condition
• Elimination of unused temporary storage queues
• Recognition of duplicate entries on the Translate table screen
• Cleanup of erroneous trace data
• Miscellaneous changes in support of business requirements
• An updated EXPCSDUP JCL job to define DCT entries with RDO

The original base product has been recompiled using Enterprise COBOL for z/OS V3R4, and CICS TS V2.2. The following updates are also included:

• During peak periods of activity when clients are sending data, recent network changes and improvements in processor speed have periodically allowed a DUPREC condition to occur for the EXPSDAT file. When the DUPREC condition occurs, the following messages may be produced and at times, a loop may occur.
  
  In the EXPTCPIP log
  
  EXPOTISO 0000000000000000FAILURE ON EZASOKET RECV CALL
  
  In the EXPLOG1 log
  
  EXPOTISO HI127 TCP/IP RECV CALL FAILED.
  
  
  Changes have been made in managing keys and records within Expedite/CICS to reduce the likelihood of the DUPREC condition.
  
  
• Occasionally, the following error appears in the EXPTCPIP log due to some garbage characters being passed in the TCP-START command.
  
  In the EXPTCPIP log
  
  EXPOTISO 0000000800000016INVALID TCPIP PORT
  
  Changes have been made to clear the storage areas that are used to build the TCP-START command so that any additional garbage characters will not be processed.
  
  
• With TCP/IP connectivity, there was an occasional Temporary Storage Queue getting created and left in CICS.
  
  A change was made to prevent this TSQ from being created.
  
  
• On the translate table screen, a change was made to indicate when a duplicate entry is on the same screen.
  
  
• A change was made to clean up some erroneous tracing data that appeared in the EXPLOG1 or EXPDTRCA/B trace queues, when using TCP/IP connectivity.
  
  
• Miscellaneous changes regarding copyrights, etc. were made due to business requirements.
  
  
• There is an updated EXPCSDUP JCL job to define DCT entries with RDO.
