Upgrading the OAR batch system
==============================

This part explains the important issues when upgrading the OAR Bach system from 2.4.x to 2.5.x.

Updating the Perl admission rules
---------------------------------

Due to a perl module renaming, you need to update the perl module name used in
the admission rules. Here are the correspondance :

     - oarstat_lib        -> OAR::Stat
     - oarnodes_lib       -> OAR::Nodes
     - oarapi_lib         -> OAR::API
     - oarconf_lib        -> OAR::Conf
     - oario_lib          -> OAR::IO
     - oarsub_lib         -> OAR::Sub
     - oar_Tools          -> OAR::Tools
     - oar_Version        -> OAR::Version
     - window_forker      -> OAR::WindowForker
     - ping_checker       -> OAR::PingChecker
     - oar_hulot          -> OAR::Modules::Hulot
     - Judas              -> OAR::Modules::Judas
     - resource_tree      -> OAR::Schedulers::ResourceTree
     - gantt_hole_storage -> OAR::Schedulers::GanttHoleStorage

The OAR default values
----------------------

Please take a look on the default oar.conf (in the
/usr/share/doc/oar-common/exemples/). Some default values has changed.

Upgrading the sql database scheme
---------------------------------

Before restarting the OAR server, you need to upgrade your database scheme.
This can be done, with the following instruction (don't forget to make a copy
of your database before):

      oar-database --setup
