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.
