OTL Syntax
DiagCom.CloseComChannel(ComChannelVariable);Description
OTX CloseComChannel activity is used for the Diagnosis Runtime System to announce that an open communication channel that all relevant resources can be released and closed.
|
Important: Long-time running procedures should note that the OTX runtime will close open ComChannels (see GetComChannel) solely via the CloseComChannel activity! This has an impact on the long-time stability of the runtime environment. To avoid memory leaks, ComChannels should not be opened implicitly, like
ExecuteDiagService(CreateDiagServiceByName(GetComChannel("LL_AirbaUDS","",false), "DiagnServi_ReadDataByIdentECUIdent"), ...);because the resources cannot be released until the completion of runtime execution. Better use: ComChannel comChannel = GetComChannel("LL_AirbaUDS","",false);
DiagService diagService = CreateDiagServiceByName(comChannel, "DiagnServi_ReadDataByIdentECUIdent"));
ExecuteDiagService(diagService, ...);
...
CloseComChannel(comChannel);For the short-dated execution of procedures, this is of minor importance! |
|
|
Important: Please note that the use of a shared ComChannel can bring the OTX runtime system in an undefined state and that is this case is not validated at design time! |
