Deploying a Spacewalk Proxy

By |2018-12-30T15:34:37+00:00January 28th, 2018|How To, Linux, Management, Monitoring, Scripts, Security|0 Comments

This article is about how to deploy a Spacewalk Proxy v2.7 from scratch. A Spacewalk proxy acts as an intermediary between Spacewalk clients and a Spacewalk server. The main purposes of a Spacewalk proxy are to mitigate the loading on the Spacewalk server and to reduce the download times for Spacewalk clients. Typically, it does make sense to roll out Spacewalk proxies on geographically remote sites. This article is based on Deploying a Spacewalk Server and is the continuation of it.

JIRA and Confluence Database Schemas

By |2018-04-28T21:48:09+00:00September 24th, 2017|Confluence, How To, JIRA|0 Comments

Here you can find the database schemas of Atlassian JIRA 7.x and Confluence 6.x. The GUI of JIRA and Confluence does not provide access to everything and does not show everything stored in databases. Sometimes you may get some unknown errors/exceptions in JIRA and Confluence logs, to troubleshoot them effectively you need to dive deeper than the GUI allows. That's why you need to be aware of how the database schema looks like to perform direct queries against a database. Also it is quite useful to extract more details to understand how to improve performance and clean out stale things.
