Concepts : Propagating and Non-propagating Files : Transfer of Other Data

Files such as ISODRAFT and external PLOT files are not propagated automatically by the Global daemon. However, there is a mechanism in the daemon to allow such files to be transferred to and from neighbouring locations.

The daemon uses environment variables to define import and export directories for other data files. At a location, there is a single directory to receive data imported from other locations; and a set of export directories, one per neighbouring location, from which data can be exported to those locations.

For the current project, the import directory at a location is defined by variable %IMPORT%; the export directory for neighbouring location ABC is defined by variable %EXP_ABC%, etc. If these variables are defined at each location, then the daemon will automatically transfer files in these directories from one Satellite to another during scheduled updates (or when the UPDATE ALL command is used). Files can only be transferred between neighbouring locations, and this method cannot be used to send files to/from off-line locations.

For example, myfile has been produced at Satellite AAA and is needed at neighbouring location BBB. The user at AAA must make sure that myfile has been placed in directory %EXP_BBB%. During the next scheduled update with BBB, this file will be sent to BBB, and received in directory %IMPORT% at location BBB. A user at BBB can then use myfile. If myfile is to be sent on to other locations, it will need to be copied into the export directories at BBB for those locations.
