DEV, TST, and PRD instances on IonMan

There are three different workflow instances on IonMan:

• PRD - Production, the default instance.
• DEV - Development, only used by developers
• TST - Testing, used to validate changes made to the DEV instance

When you connect to IonMan, you will see "[PRD]" at the end of your prompt. This means that the tools you are using will be the production versions. It also means that the $JOBS environment variable evaluates to /data/PRD/jobs

Submitting Jobs to the various instances

Each instance has it's own file share available for job submission:

• \\ionman.chem.indiana.edu\jobs (production)
• \\ionman.chem.indiana.edu\DEVjobs (development)
• \\ionman.chem.indiana.edu\TSTjobs (testing)

You may also access these directories from UNIX:

• /data/PRD/jobs
• /data/TST/jobs
• /data/DEV/jobs

Switching your current instance

If you would rather be using the DEV tools, you can switch instances using the "*switch*" command. The syntax is unusual, but simple:

. switch DEV

You really do need that "." with a space afterwards in the beginning. This tells your shell to import that script into your current environment, rather than running it inside of a subshell.

Migrating code between instances

If you are a developer, you may be called to migrate code from DEV to TST, and eventually TST to PRD. Doing so is pretty easy. This migrates the current DEV code to TST:

sudo rsync -vac --delete /data/DEV/bin/ /data/TST/bin/
sudo chmod -R 755 /data/TST/bin

When run, it will give you a list of what files were removed, and which were added or changed.
