Configuration for multiple curators

We’d like to use Pathway Tools in a way that allows for multiple people to curate the same PGDB. How does one do that?

If you plan to have multiple curators update a PGDB, there are several possible ways to configure their usage of Pathway Tools.

First, we recommend that each PGDB that will be curated be stored in a single relational database management system (RDBMS). Oracle and MySQL are the two RDBMSs currently supported by Pathway Tools. All PGDBs can be stored within one DBMS server.

This configuration allows multiple curators to access and update the PGDB in parallel. The Pathway Tools that they run will access the DBMS through network queries.

Curators can run and access Pathway Tools in several possible ways:

  • A separate instance of Pathway Tools can be installed on each curator’s workstation.
  • Curators can access a single shared instance of Pathway Tools via X-Windows. For example, a curator could run an X-window desktop on their Windows-NT computer, with Pathway Tools running on a separate Unix computer, and the Pathway Tools windows are transmitted via the network to the Windows-NT desktop.
    Each simultaneous Pathway Tools user on the Unix computer will require 300-500MB of RAM.
  • Curators with NFS access to a Pathway Tools instance can each run Pathway Tools on their own workstation, but can access a single Pathway Tools installation. This option is probably the optimal one since it requires only a single installation of Pathway Tools, yet it allows each curator to run Pathway Tools on a separate computer.
