• python interface( See ecflow.ZombieAttr)

• text interface ( See Definition file Grammar)

  zombie             ::=  "zombie" >> `zombie_type` >> ":" >> !(`client_side_action` | `server_side_action`) >> ":" >> *`child` >> ":" >> !`zombie_life_time`
  zombie_type        ::=  "user" | "ecf" | "path" | "ecf_pid" | "ecf_passwd" | "ecf_pid_passwd"
  child              ::=  "init" | "event" | "meter" | "label" | "wait" | "abort" | "complete"
  client_side_action ::=  "fob" | "fail" | "block"
  server_side_action ::=  "adopt" | "delete | "kill"
  zombie_life_time   ::=  unsigned integer( default:  user(300), ecf(3600), path(900)  ), the server poll timer runs every 60 seconds, hence this is the effective minimum value
  Where:

     ecf_pid                -  PID miss-match, password matches. Job scheduled twice. Check submitter

     ecf_pid_passwd - Both PID and password miss-match. Re-queue & submit of active job?

     ecf_passwd        - Password miss-match, PID matches, system has re-cycled PID or hacked job file?

     ecf                      - Two init commands or task complete or aborted but receives another child cmd

     ecf_user             - Created by user action

     ecf_path            - Task not found. Nodes replaced whilst jobs were running

  
  

• --alter command(dynamic)
       ecflow_client --alter add zombie <zombie-attribute>  <path>
       ecflow_client --later delete zombie < ecf | path | user>  <path>
  However note, the effect will only be seen, when the child command, makes the next attempt to communicate with the server.

...

Example: For tasks under suite “s1” add a zombie attribute, such that job that issues the child commands( event, meter, label) never blocks: (not strictly needed as this is the default behaviour from release 4.0.5 onwards)

• python

  s1 = ecflow.Suite('s1')
  child_list = [ ChildCmdType.label, ChildCmdType.event, ChildCmdType.meter ]
  zombie_attr = ZombieAttr(ZombieType.ecf, child_list, ZombieUserActionType.fob, 300)
  s1.add_zombie(zombie_attr)
  

• text

  suite s1
     zombie ecf:fob:label,event,meter:

• alter
       ecflow_client --alter=add zombie "ecf:fob:label,event,meter:"  /s1

...

• python

  with ecflow.Suite('s1') as s1:
     with s1.add_family("critical") as crit :
        child_list = [ ]  # empty child list means apply to all child commands
  
        for crit.add_zombie(ZombieAttrzombie_type in (ZombieType.ecf, child_list, ZombieUserActionType.fail, 300))
        crit.add_zombie(ZombieAttr(ZombieType.path, child_list, ZombieUserActionType.fail, 300))
  ZombieType.path,ZombieType.user,ZombieType.ecf_pid,ZombieType.ecf_passwd,ZombieType.ecf_pid_passwd):
           crit.add_zombie(ZombieAttr(ZombieType.userzombie_type, child_list, ZombieUserActionType.fail, 300))
     

• text

     suite s1
       family critical
         zombie ecf:fail::
         zombie path:fail::
         zombie user:fail::
         zombie ecf_pid:fail::
         zombie ecf_passwd:fail::
         zombie ecf_pid_passwd:fail::

• alter
      ecflow_client --alter=add zombie "ecf:fail::"    /s1
      ecflow_client --alter=add zombie "path:fail::"  /s1
      ecflow_client --alter=add zombie "user:fail::"  /s1

              ecflow_client --alter=add zombie "ecf_pid:fail::"  /s1

              ecflow_client --alter=add zombie "ecf_passwd:fail::"  /s1
