CSAPI

CSAPI exposes update functionalities to the Configuration.

Most of these functions can only be done by administrators

class DIRAC.ConfigurationSystem.Client.CSAPI.CSAPI

Bases: object

CSAPI objects need an initialization phase

__init__()

Initialization function

addCEtoSite(siteName, ceName, optionsDict=None)

Adds a new CE to a site definition in the CS. A CE normally has queues, so addQueueToCE should be called after this one.

Parameters

• siteName (str) – FQN of the site (e.g. LCG.CERN.ch)

• ceName (str) – FQN of the CE (e.g. ce503.cern.ch)

• optionsDict (dict) – optional dictionary of options

Returns

S_OK/S_ERROR structure

addGroup(groupname, properties)

Add a group to the cs

Parameters

• groupname (str) – group name

• properties (dict) –

  dictionary describing group properties:

  • Users

  • Properties

  • <extra params>

Returns

S_OK, Value = True/False

addHost(hostname, properties)

Add a host to the cs

Parameters

• hostname (str) – host name

• properties (dict) –

  dictionary describing host properties:

  • DN

  • Properties

  • <extra params>

Returns

S_OK, Value = True/False

addQueueToCE(ceName, queueName, optionsDict=None)

Adds a new queue to a CE definition in the CS.

Parameters

• ceName (str) – FQN of the CE (e.g. ce503.cern.ch)

Returns

S_OK/S_ERROR
