DBCHCL calculates the value of Open-requests as follows:

Open-requests is the number of calls to DBCHCL for Connect function
  + the number of calls to DBCHCL for RunStartUp function
  + the number of calls to DBCHCL for Initiate Request function
  + the number of calls to DBCHCL for Initiate with Protocol-function function
  + the number of calls to DBCHCL for Command function
  the number of calls to DBCHCL for End Request function
  • The calculation does not keep track of End Request parcels as received by the client nor does it keep track of the return code from the call to DBCHCL.
  • The application must explicitly close a request with an End Request function in order to have Open-requests decremented.
