Processes/Jobs

The RDMS web interface allows you to observe certain processes/jobs that you do via the web interface. For that, the Processes/jobs view on the left-side menu can be used. Moreover, this view allows you to observe the status of your Delayed Rules, a concept that will be explained in this section as well.

Processes/Jobs in the Web Interface

If you perform certain operations in the RDMS web interface, these get registered as processes. The status of these processes can be observed here.

Currently, the following operations are visible as processes:

  1. Uploading of data via the web interface
  2. Bundling operations (compress to tar or decompress)
  3. Extraction of metadata
  4. Different steps of the Archiving Workflow

By clicking on a listed process, you can get more details about it.

This shows you, for example, the kind of process and the data on which it was executed. Moreover, every process gets a process number as well as a ID. The ID can be used to correlated the job to a Delayed Rule (see below) if applicable.

Note: Not all jobs are executed as Delayed Rules as will described below. For example the upload operation, is not a delayed rule, but it has a Delayed Rule associated with it that is executed in the background (computation of data checksum).

Delayed Rules

The RDMS is built on top of the data management software iRODS. The iRODS system has the in-built capability to execute certain task when a certain event is registered in the system. This automated tasks are called rules and they can be delayed, meaning being queued and executed in the background even if the user is not logged in anymore.

We use rules at several places in the RDMS, often as delayed rules. Important example of delayed rules are:

  • Automated checksum calculations of your data: If you upload files to the RDMS, a automated checksum calculation for your files with be executed as a delayed rules. This guarantees that all your files have a checksum registered which gives you/us the capability to check the integrity of your data.
  • Bundling/Unbundling via the web interface: If you use the function to compress a folder to a tar archive or to decompress a tar archive, it will be also executed as a delayed rule.

You can observe the status of your rules via the second tab in the processes/jobs view.
