General upgrade instructions for a factory

These instructions assume that you are only upgrading the factory. If you need to upgrade more components, it may involve additional steps. Upgrading a factory can be done in two ways:

  • Installing the new glideinWMS code in a separate directory, and create a new configuration tree.
    The configuration file (glieinWMS.xml) of the existing configuration tree may be used as a base for the new one; only the glidein_ name needs to be changed. See the configuration page for more defaults.
  • Overwrite the glideinWMS installation and run: factory_startup upgrade config.xml.
    If getting the code from CVS, a cvs update -r version will update the code.
    Running 'upgrade' overwrites all files in the glidein submit directories including rewriting the configuration file. If you use 'reconfig', this will only upgrade the files with factory configuration information so some of the scripts may not get updated.

Which option you choose is really up to you; the second one is easier, but the first one is cleaner and easier to revert back.

Warning: Check the revision history before doing this. Not all versions are compatible. For example, changes to a factory configuration file may not allow you to reuse an old glideinWMS.xml.

Upgrading from v2+ to v3+

We normally don't recommend major version upgrades as there are significant changes to the configuration files and content in the working directories.

Starting v3.1, glideinwms provides tools to convert v2.7 config files and rrds to v3.1 equivalent. See below for detailed steps to upgrade factory and frontend.

    prompt$ ./convert_frontend_2to3.sh
    Usage: convert_frontend_2to3.sh <options>
    where <options> are:
    -s <path>             : path to top directory glideinWMS source
    -i <frontend-2.xml>   : v2 frontend.xml
    -o <frontend-3.xml>   : v3 frontend.xml

    prompt$ ./convert_factory_2to3.sh
    Usage: convert_factory_2to3.sh <options>
    where <options> are:
    -s <path>               : path to top directory glideinWMS source
    -i <glideinWMS-2.xml>   : v2 glideinWMS.xml
    -o <glideinWMS-3.xml>   : v3 glideinWMS.xml

    prompt$ ./convert_factory_rrds_2to3.sh
    Usage: convert_factory_rrds_2to3.sh <options>
    where <options> are:
    -c <glideinWMS.xml>   : full path to the v3 glideinWMS config file
    

The upgrade process is not fully automated and involves few steps. NOTE: Please back up your configurations (they can be a reference for any customizations you have done) when reinstalling the services.

Upgrading from v1+ to v3+

We do not support upgrading from v1+ to v3+. There are too many changes between these versions and reinstallation of ALL services is required.
