How to speed up file transfer between Z/OS-Agents and AIX- or Windows-Agents

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

The file transfer of a 280 MB file between Z/OS-Agents and any other System Agent needs about 11 to 13 minutes. This definitely too long, compared to other existing third party solutions.

 

Environment

Release : 12.0 Component : AUTOMATION ENGINE AGENTS

Cause

HOST Characteristics Parameters set for synchronous and asynchronous file transfer are not set properly. 

Resolution

1. In the configuration files of both involved agents set

sendBufferSize and recvBufferSize to 2MB  (maximal 4 MB can be taken).

2.Change the values within UC_HOSTCHAR_* Variable assigned to these agents :
FT_ASYNC_QUIT_MAX / FT_ASYNC_QUIT_MIN / FT_ASYNC_QUIT_NUM
to:
60 / 0 / 60

Save the VARA and restart both Agents

Additional Information

If the problem still persists applying these changes, activate the following trace levels on both agents:

-- tcp/ip=2

-- file_transfer (Windows Agent) or ft_debug=3

-- memory=1

Run file transfers jobs in both direction and provide the trace and logs from both agents.

Provide as well the RunIDs of both transfers.
