  • Closed as program error.

Error description

  • Communications Server for Windows
    ---------------------------------
    When a program is run on an API Client system and issues a
    SLI_CLOSE call, that call gets converted to an ABEND and
    triggers an UNBIND with sense code 08A00002 sent to the host
    application. This does not happen when the same program is run
    directly on the server.
    
    When a program is run on an API Client system and issues a
    SLI_BID call, that call may sometimes be returned with
    lua_message_type=0x41 (LUA_INVALID_MESSAGE_TYPE) instead of the
    correct message type. This does not happen when the same program
    is run directly on the server.
    

Local fix

Problem summary

  • The SLI application runs on the Remote API Clinet wait on the
    BID, where the CS/Windows server terminate the session with BID
    outstanding and never post the BID to application.
    

Problem conclusion

  • API Client module make the close type as ABEND, where there is a
     BID outstanding, which drives UNBIND instead of RSHUTD. Now, if
     there is a BID outstanding then the SLI_CLOSE will be
      consider as normal close, which drives RSHUTD.
    

Temporary fix

  • csnia.dll
