We uncovered a Stata bug where the application will overwrite output with zero byte content when you reach maximum quota. Please be aware of your quota status and expected output size before running a Stata job. HMDC has submitted a bug report to Stata and their developers are working on a fix.
Yes, but access is limited to within the RCE only. Create or log in to your NX session and navigate to phpmyadmin.hmdc.harvard.edu. Log in to phpMyAdmin using your database credentials. Make sure the proper host is selected in the drop down. If you don't know your host, check the email that was sent to you when you requested the database.
When running an RCE Powered Application -- for example an RCE Shell -- you have the opportunity to reserve a requested amount of system memory. Unfortunately, the Java JRE is not aware of the resource limit you have set, and will try (and fail) to grab as much of the system memory as is free.
The commands below will help you exit an RCE job from a terminal if the application window has disappeared, or you need to exit it and do not have access to your NX session. This can be accomplished by using an ssh client and connecting to rce.hmdc.harvard.edu, or opening a terminal window in the RCE.
