Common __init__ method for all Agents. All Agent modules must define: __doc__ __RCSID__ They are used to populate __codeProperties

The following Options are used from the Configuration: - /LocalSite/InstancePath - /DIRAC/Setup - Status - Enabled - PollingTime default = 120 - MaxCycles default = 500 - WatchdogTime default = 0 (disabled) - ControlDirectory control/SystemName/AgentName - WorkDirectory work/SystemName/AgentName - shifterProxy ‘’ - shifterProxyLocation WorkDirectory/SystemName/AgentName/.shifterCred

It defines the following default Options that can be set via Configuration (above): - MonitoringEnabled True - Enabled True if Status == Active - PollingTime 120 - MaxCycles 500 - ControlDirectory control/SystemName/AgentName - WorkDirectory work/SystemName/AgentName - shifterProxy False - shifterProxyLocation work/SystemName/AgentName/.shifterCred

different defaults can be set in the initialize() method of the Agent using am_setOption()

In order to get a shifter proxy in the environment during the execute() the configuration Option ‘shifterProxy’ must be set, a default may be given in the initialize() method.

execute()

This is the main method of the agent. It gets the sites from the Database, calculates how many threads should be started and spawns them. Each thread will get a site from the queue until it is empty. At the end, the method will join the queue such that the agent will not terminate a cycle until all sites have been processed.
