Environment

Release : 9.4, 9.4.1

Component : APPLICATIONS MANAGER

Cause

This issue is due to the Agent expecting to find a number of "Shared" parameters in the Master's awenv.ini, but is not present.

 

Resolution

Edit the $AW_HOME/site/awenv.ini or %AW_HOME%\site\awenv.ini (Windows) on both the Master and Remote Agent, and add the following lines to the bottom of the file.

[shared]
sshdserver_portrange=50000:50010
cmd_w_updatemaster=_AW_HOME_/exec/dr_agent.bat
cmd_u_updatemaster=_AW_HOME_/exec/dr_agent.sh

Save and restart both master and agent.
