Running processes

Now that the core warehouse components are created, let's run them to confirm the setup is correct.

Run the messaging server ds_ms_a if not already.
Right-click the kxw_tp service class in the workspace tree
Click the Run button in the context menu
A dialog will appear
A host must be specified but all other parameters are optional
Click the Run button

Once the service is running, it should appear in your Process Library Status Viewer. The Status column can be filtered for running processes to reduce the list.
Perform the same steps for the other services.
- kxw_rdb
- kxw_lr
- kxw_ihdb
- kxw_hdb
Your Process Library should look similar to this:

More information is available on running service classes.

Service classes

Run warehouse

To run all of the service classes created at once you can use the script provided in the Warehouse Appendix.

This script takes in a CSV which is also provided.
It then runs the startService.sh script against each of the services provided in the csv.
You will need to firstly create a bin and config directory where you have the package checked out.
The startServiceCSV.sh will go in the bin directory.
The system.csv containing your services will be in the config directory.
To then run the script from the bin directory use this command:
```
./startServicesCSV.sh ../config/system.csv
```

You may have to source the delta.profile

The startServicesCSV.sh reads your delta.profile and delta_user.profile. Sourcing the delta.profile manually will export the variables so the script will be able to locate them.

Loading data

There are two typical scenarios for loading data into these processes; batch load from files and realtime streaming. These are discussed in detail in the next two sections.

The filewatcher is used for loading batch data into the system from files. These files can be in a number of format including CSV, JSON and fixed-width binary.

File Watcher

The other is realtime data captured from a feed. In reality, the data will flow in from an external source, but for the purpose of this document, we will mock a feed and pass in dummy data to the system.
