\"wl-gold\"<\/a>IT Services has just launched a brand new project aimed at improving the resilience of WebLearn. The project which started in June 2014 and will run for 9 months aims to improve the infrastructure that supports the WebLearn architecture.<\/p>\n

WebLearn is now classified by the University as a Tier 1 service. This means that it is essential to the business of the University and must suffer from minimal unplanned downtime.<\/p>\n

Even though the reliability of WebLearn has been very good of late, there are still improvements that can be made. WebLearn runs in a physical cluster of 4 machines: one\u00a0 back-end server which hosts the MySQL database and SOLR search platform and a further 3 worker nodes which host the rest of WebLearn.<\/p>\n

There have been a couple of occasions when a problem with SOLR has put a strain on the back-end server and caused the database to run slowly – to an end user, this makes WebLearn appear sluggish with slow response times.<\/p>\n

On other occasions, we have noticed ‘runaway threads’ on one of the worker nodes – to an end user who is using this node, again, the service will appear to be labouring.<\/p>\n

The objectives of WeRP are that robustness and recovery time should be improved, this will result in less unplanned downtime for users and should also give overall faster response times.<\/p>\n

Certain kinds of problems will be able to be identified quicker and users will be less inconvenienced when there is a problem as it will be easier and quicker to take a node out of services in order to repair a problem. Improved monitoring & access to logs will allow both IT Services to diagnose past issues and respond to user queries.<\/p>\n

The project is at a very early stage and is still in the planning phase – keep an eye on this blog for updates of progress as an when they happen.<\/p>\n","protected":false},"excerpt":{"rendered":"
