RHBA-2017:1683 - Bug Fix Advisory

Topic

Updated spacewalk-backend, spacewalk-schema, and satellite-schema packages that fix two bugs are now available for Red Hat Satellite 5.6.

Description

Red Hat Satellite is a systems management tool for Linux-based infrastructure. It allows for provisioning, monitoring, and remote management of multiple Linux deployments with a single, centralized tool. The spacewalk-backend packages contain the code for the python code that manages the server side of the client-to-satellite-server communication paths.

This update fixes the following bugs:

• A previous fix to prevent double counting systems caused a performance degradation during registration for a Satellite with a large number of registered systems. With this update, the restriction has been reverted and the performance degradation no longer occurs. (BZ#1445406)
• Under heavy load, reactivating systems and deleting systems at the same time could cause a database deadlock. This behavior has been corrected. (BZ#1459964)

All users of Red Hat Satellite are advised to upgrade to these updated packages, which fix these bugs.

Solution

Application of this errata involves updating the database schema.

For general instructions on the database schema upgrade, consult the following document first: https://access.redhat.com/site/articles/273633
