WebJCL Maintainence

WebJCL was originally developed to save the last 5 job submissions for convienence sake. In the end this was never adequately implemented with MongoDB and instead ALL submissions are saved. After awhile it runs out of memory/disk on small vps.

Instructions on how to backup/clear the database

(Optional Backup) Open up a SSH tunnel to the host with mongodb

# Make the remote mongo instance appear on the localhost
ssh -N -L 27017:localhost:27017 ssh-hostname

# Dump the entire mongodb to $PWD/dump
mongodump

Drop the database

# Inside the mongo shell
    
use WebJCL
db.dropDatabase()

Alternative if the above doesn't work

# Run the following on the host which contains mongodb

# Stop mongodb EX:
sudo service mongodb stop

# Delete database files
rm -rf /var/lib/mongodb

# Start mongodb EX:
sudo service mongodb start
