Helper for accessing /Operations

/Operations section is VO and setup aware. That means that configuration for different VO/setup will have a different CS path:

  • For multi-VO installations /Operations/<vo>/<setup> should be used.

  • For single-VO installations /Operations/<setup> should be used.

In any case, there is the possibility to define a default configuration, that is valid for all the setups. The Defaults keyword can be used instead of the setup. For instance /Operations/myvo/Defaults.

Parameters defined for a specific setup take precedence over parameters defined for the Defaults setup. Take a look at Operations - Section for further info.

To ease accessing the /Operations section a helper has been created. This helper receives the VO and the Setup at instantiation and will calculate the Operations path automatically. Once instanced it’s used as the gConfig object. An example would be:

from DIRAC.ConfigurationSystem.Client.Helpers.Operations import Operations

ops = Operations(vo="dirac", setup="Production")
#This would check the following paths and return the first one that is defined
# 1.- /Operations/dirac/Production/JobScheduling/CheckJobLimits
# 2.- /Operations/dirac/Defaults/JobScheduling/CheckJobLimits
# 3.- Return True

print(ops.getValue("JobScheduling/CheckJobLimits", True))

It’s not necessary to define the VO if a group is known. The helper can extract the VO from the group. It’s also possible to skip the setup parameter and let it discover itself. For instance:

from DIRAC.ConfigurationSystem.Client.Helpers.Operations import Operations

ops = Operations(group="dirac_user")
