This request count is kept in the HTTPConnection // object. The request count is incremented everytime a request comes through // a client connection, and is decremented everytime a response is sent back // to the client. // // Before the ShutdownService shuts down the CIMServer, the request count is // checked to determine if there are any outstanding CIM requests being // processed. If there are no requests outstanding, the CIMServer will be // shutdown. If there are requests outstanding, the ShutdownService will // wait periodically until the requests are all processed or until the // timeout expires before shutting down CIMServer. // /////////////////////////////////////////////////////////////////////////////// */ class PEGASUS_SERVER_LINKAGE ShutdownService { public: /** Terminate the ShutdownService */ static void destroy( void ); /** Construct the singleton instance of the ShutdownService and return a pointer to that instance. */ static ShutdownService* getInstance(CIMServer* cimserver); /** Shutdown CIMOM. @param requestPending Boolean indicating whether the shutdown was initiated through a synchronous CIM request (true) or not (false). */ void shutdown(Boolean force, Uint32 timeout, Boolean requestPending); void shutdownCimomServices(); Boolean waitUntilNoMoreRequests(Boolean requestPending); protected: static pegasus_internal_identity _id; static ModuleController * _controller; static ModuleController::client_handle *_client_handle; private: static ShutdownService* _instance; static CIMServer* _cimserver; static Uint32 _shutdownTimeout; // // This is meant to be a singleton, so the constructor and the // destructor are made private. // /** Constructor. */ ShutdownService(CIMServer* cimserver); /** Destructor. */ ~ShutdownService(); void _shutdownCIMServer(); void _resumeCIMServer(); void _sendShutdownRequestToService(const char * serviceName); void _shutdownProviders(); void _initTimeoutValues(Uint32 timeoutParmValue); }; PEGASUS_NAMESPACE_END #endif /* Pegasus_ShutdownService_h */
