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
