The DBA view dba_jobs_running isn't as useful on a RAC because it uses v$lock instead of gv$lock, so it only shows the jobs running on the instance you're logged in to. Here is a RAC version of dba_jobs_running.
/* RAC dba_jobs_running */
select v.SID, v.id2 JOB, j.FAILURES,
LAST_DATE, substr(to_char(last_date,'HH24:MI:SS'),1,8) LAST_SEC,
THIS_DATE, substr(to_char(this_date,'HH24:MI:SS'),1,8) THIS_SEC,
v.INST_ID instance
from sys.job$ j, gv$lock v
where v.type = 'JQ' and j.job (+)= v.id2
;
