### Support Tools Installation
Before installation of the APS Data Management System a number of tools need to be installed on the server nodes. The __DM__ system depends on tools such as Java, Python, Postgresql, MongoDB, ZeroMQ, etc. A set of scripts have been established which will download, build (when necessary) and install these tools for use with the __DM__ system. While it is possible to install most of these tools using more conventional means (e.g. RPM on Linux) the install scripts provided here builds and installs these tools specifically for use with the __DM__ system.
For the purposes of this tutorial, we will are creating two nodes which will contain different pieces of the __DM__. One node will be referred to as the data-storage node. This will contain the data storage web service and the Postgresql database which conatains the user database. The second node will be reffered to as the exp-station node. This node will provide the cat web service (a catalog of the stored data), the daq web service (provides a way to move collected data) and the proc web service (provides a means to process data).

The subdirectory paths will be constructed from beamline name, experiment name and a path specified by the user in the transfer setup.

You should at this point have a directory installed which has both the _Data Manangement_ and _support_ software installed. After doing the installs described above there should be a number of other directories as well such as etc, log and var. We are now going to walk through changes needed in the etc directory which will allow us to interact with the system.
1. source the file _etc/dm.setup.sh_. For now, this will be done on both nodes. This defines a number of environment variables and modifies the path to include, in particular, a number of commands beginning with __dm-__ which interact with the underlying system to add/modify users, experiments, upload and daq (both to move files) and workflows and processes (to define & monitor processing of the collected data). Normally, you will only do this on exp-station since most operations will be done there.
