APAR status

  • Closed as program error.

Error description

  • If you issued CONNECT statement multiple times without any
    DISCONNECT or CONNECT RESET between them, DB2's registry
    variable DB2TCP_CLIENT_RCVTIMEOUT would be set to 0 ever since
    the 2nd time of CONNECT statement.
    
    This problem only happens when both DB2TCP_CLIENT_RCVTIMEOUT and
    DB2TCP_CLIENT_CONTIMEOUT are enabled.
    

Local fix

  • 1. Starting from the 2nd CONNECT statement, issue DISCONNECT or
    CONNECT RESET statement prior to CONNECT statement.
    2. Use DB2TCP_CLIENT_RCVTIMEOUT only, do not use registry
    variable DB2TCP_CLIENT_CONTIMEOUT.
