Prevent overlapping cyclic job executions in ESP Workload Automation

Products

• ESP Workload Automation

Issue/Introduction

High-frequency cyclic jobs (e.g., every 2 minutes) in ESP Workload Automation may overlap if the execution time of a previous generation exceeds the trigger interval. This behavior results in a buildup of queued jobs.

Resolution

ABANDON SUBMISSION coded at lob level will bypass job if previous job is still running.

Example is for a cyclic job to run every 2 minutes between 2am and midnight.

 APPL ######## WAIT                             
 INVOKE '########.ESP.PROCS(#GLOBALS)'          

JOB PBD909M.MIN                                    
  RUN TODAY                                          
  ABANDON SUBMISSION REALNOW PLUS 2 MINUTES          
  IF ESPATIME < '02.00' THEN NORUN TODAY             
  IF ESPATIME > '23.59' THEN NORUN TODAY             
ENDJOB
