PM73494: ECI_ERR_INVALID_DATA_LENGTH is returned when flowing a 32767 byt e COMMAREA to IPIC connected CICS servers.

CICS Transaction Gateway for Multiplatforms V7.2.0 Fix Pack 4

APAR status

• Closed as program error.

Error description

• When an ECI request with a 32767 byte COMMAREA is sent to an
  IPIC connected CICS server, return code -1
  ECI_ERR_INVALID_DATA_LENGTH is received.
  

Local fix

• Use 32766 byte COMMAREAs or IPIC channels and containers
  support.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of CICS Transaction Gateway and IPIC connected CICS
  servers.
  ****************************************************************
  PROBLEM SUMMARY:
  When sending ECI requests to IPIC connected CICS servers, CICS
  TG was incorrectly restricting the maximum COMMAREA length to
  32766 bytes. The maximum usable size of a COMMAREA when using
  the IPIC protocol is 32767 bytes.
  ****************************************************************
  

Problem conclusion

• CICS TG has been changed to allow a maximum COMMAREA length of
  32767 bytes to be flowed over IPIC connections. ECI requests
  specifying COMMAREAs longer than 32767 bytes will continue to
  receive ECI_ERR_INVALID_DATA_LENGTH. This change does not
  affect non-IPIC protocols.
  

Temporary fix
