GGUS – Global Grid User Support


This is the GGUS change implementation process. For general information see the GGUS documentation pages.

'Change implementation process' GGUS system consists of 3 instances: development, test and production. All changes including patch installation for the OS are done on development instance first. In the next step changes are propagated to the test instances for intensive testing by GGUS team and by users from the communities if necessary. In case no problems occure on test instances changes are scheduled for installation on production instances.

'Software version and patch installation' GGUS software is under control of a version control system. For installation all changes are packaged in rpm files which are installed using package manager yum. This allows to keep control on the installed patches and roll back easily in case of unexpected problems after a change.
