Hi all,

We're looking at how we should launch CS-Studio BOY screens on beamlines and machine, and have the following requirements:
1) If an IOC has a database template instance from a motor version 6-5, the screens for that IOC should come from motor 6-5.
2) One insertion device may have all its IOCs pointing at motor 6-5, but another may be at 6-4 or 6-2.
3) A user may want to launch sets of screens for many insertion devices at the same time.

The same is true for beamlines, front ends, and other technical areas: a user may start at a high level screen, and drill down to a different version of the motor screen depending which IOC that component is on.

For EDM we simply launched a new EDM for each insertion device with its own search path, but doing the same with CS-Studio would be quite resource hungry. We have had more than 20 instances of EDM running at once, and I wouldn't like to do the same with java virtual machines.

We have come up with a proposal that would work for us:
* Create a project for each insertion device (and beamline etc.) with soft links to the versions of each support module it uses
* Run a command that tells the current running CS-Studio to import that project to the user's workspace and run a screen within it
* We could then have one CS-Studio instance, and let each user have their own workspace, but manage the locations of the projects within it ourselves

The eclipse navigator file structure would look like this:

workspace/ # located in user's home directory
  CSS/
  ID1/     # Eclipse project pointing to /dls_sw/.../ID1/2-0
    motor/ # Soft link in /dls_sw/.../ID1/2-0 pointint to /dls_sw/.../motor/6-5
  ID2/     # Eclipse project pointing to /dls_sw/.../ID2/3-0
    motor/ # Soft link in /dls_sw/.../ID1/3-0 pointint to /dls_sw/.../motor/6-2

Has anyone else done anything similar? How do other sites launch CS-Studio BOY screens?

Thanks,
Tom Cobb
