Best Practice to use File Triggers and VIP(F5 load balancer) on CA Workload Automation ESP Edition

Products

• ESP Workload Automation

Issue/Introduction

We are working on a project that will require 100+ file triggers and the setup uses a VIP (F5 load balancer).

Environment

CA WA ESP Edition Z/OS

Resolution

We recommend that:
- Install PTF RO94300:
PROBLEM DESCRIPTION:                                                     
If an agent cluster is used for File_Trigger jobs, the agent name used   
in the message sent to delete a file trigger entry to the agent contains 
the agent cluster name instead of the name of the agent actually         
monitoring the files. Accordingly, when a File_Trigger job is being      
completed, a delete file trigger message may be sent to a wrong agent    
causing file trigger entries to never be deleted. This causes agent      
initiators on the right agent not being released and eventually stops    
the agent from accepting new requests. This fix corrects this problem.   
                                                                         
- Increase RETRYINTERVAL (like the whole cycle of the round robin) for related agents in AGENTDEF table, so that ESP will not send duplicate requests.
