	QPR ProcessAnalyzer models can be loaded automatically into the server memory already when the ~~server~~ starts. When models are large and loading takes a long time, it's useful to ~~pload~~ the models in advance. The automatic loading can be switched on in the '''Model properties''' dialog (available in the models list in the header) in the '''Details''' tab by ~~changing~~ the '''Load Model on Startup''' checkbox.		QPR ProcessAnalyzer models can be loaded automatically into the backend server memory already when the system starts (e.g. after software update). When models are large and loading takes a long time, it's useful to load the models in advance. The automatic loading can be switched on in the '''Model properties''' dialog (available in the models list in the header) in the '''Details''' tab by selecting the '''Load Model on Startup''' checkbox.

	~~For~~ models ~~that~~ are ~~set~~ to ~~load automatically on~~ server ~~startup~~, ~~you also need to set~~ the ~~'''Drop Unused Model After''~~ setting ~~to a large value to make sure that it remains in~~ the ~~memory even if it's~~ not ~~used (e~~.~~g. ''100.00:00:00'')~~.		It's possible to control how many models are loaded at the same time, to limit how much server capacity the model loading can use. The default value is two models at the same time. To change this setting, see the [[PA_Configuration_database_table\|PA_Configuration table]]. This setting only affects the model loading on startup (not model loading initiated by users). If loading of a model fails, the loading continues with the next model.

If loading of a model fails, the loading continues to the next model.		Model loading is also started, when running a calculation for the model. When a calculation, that initiated a model loading, is cancelled, model loading is still continued. If a calculation is waiting for a model loading to complete, and model loading is cancelled, an error is returned to user waiting for the calculation.
