8.11. Clearing Broker and Management Console Application Cache

In production mode, Rails caches certain values on the broker for faster retrieval. Clearing the broker and Console cache allows the retrieval of updated values. The number of files in both caches will increase over time, until eventually the system will run out of inodes. This can be harmful to your system.
Performing Regular Cache Maintenance

Creating a cron job to regularly clear the cache at a low-traffic time of the week is useful to prevent your cache from reaching capacity. Add the following to the /etc/cron.d/openshift-rails-caches file to perform a weekly cron job: 

# Clear rails caches once a week on Sunday at 1am
0 1 * * Sun root /usr/sbin/oo-admin-broker-cache -qc
0 1 * * Sun root /usr/sbin/oo-admin-console-cache -qc

Manually Clearing the Cache

Alternatively, you can manually clear each cache for an immediate refresh. Clear the broker cache with the following command: 

# oo-admin-broker-cache --clear
Copy to Clipboard Toggle word wrap
Clear the Management Console cache with the following command: 
# oo-admin-console-cache --clear
Copy to Clipboard Toggle word wrap
