The VAST Platform installer deals with three kinds of files: read-only files, read-write files which can be shared and files specific to a user. The first are termed program files, the second sharable files and the last private files. The installer places read-only product files and shareable files into distinct directory trees as described below for use by several users. Environments copies and creates files private to a particular user.

The installer places the read-only product files into a specific directory tree accessible by many users. The root directory of VAST Platform program files (varoot) is

The team administrative tools – emadmin and emsrv -- are installed in <varoot>/bin.

Because it is a read-write file, the library (code repository, mgr1000.dat) is placed in a shared location (mgrroot) which defaults to:

The System Administrator may move the library to another location with appropriate permissions - all client ini files must then be updated to reflect the new location.

The library (mgr1000.dat) is not shared by the 32-bit and 64-bit installers.

Since development environments belong to a single user, they must be placed in a directory to which an application programmer has read/write access. By default, this directory (envroot) is: /home/<username>/Instantiations/VASTPlatform, where /home/<username> is the user’s home directory.

The Environments tool helps you to set up a development environment (including image, ini and other user modifiable files) in a directory under envroot whose name you choose.

The Environments tool is included with each installation. These two Environments tools share private files like the data (Environments.dmp) file, so changes made by one copy of Environments will show up in the other.
