channel_state values

Value Allocate Fetch Description
Active ok ok -
Inactive ok - Allocate jobs to the channel but do not start transfers.
Drain - ok Channel must be emptied: finish current transfers but do not allocate new ones.
Halted ok - Same as Inactive but should be used e.g. by monitoring scripts to signal a problem (while Inactive is set by the administrator for maintenance). It is disable by default.
Stopped - - No job allocation, no new transfers started (transfer agent should not even start).
Archived - - The channel does not exist anymore (but the entry in the table must be kept).


Stores the permissions for a VO on a channel.

column description comments
channel_name the name of the channel -
vo_name The name of the VO -
channel_share The percentage of the channel resources associated to the VO See description.
channel_limit The limit (i.e. cap) in the number of concurrent transfers for this VO It's an absolute number
channel_vostate The VO specific state (ON/OFF/PAUSE) See description.


For a couple CHANNEL_NAME / VO_NAME the CHANNEL_SHARE value has the following meaning:
  • The value does not exist: the VO cannot use the channel. The VO is anyway authorized to use another channel.
  • 0: it is possible to allocate but not to start new jobs. Deprecated: better use CHANNEL_VOSTATE.
  • > 0: it is possible to allocate and to start new jobs.


Value Allocate Fetch Comments
ON ok ok -
OFF no, allows fallback ok like drain
PAUSE ok - -
DENY no, does not allow fallback ok (if jobs are present, allow draining the channel) used to deny a VO the permission to execute transfers between a site/cloud and another
