Products

• DSERIES- SERVER
• CA Workload Automation DE - System Agent (dSeries)

Issue/Introduction

CA WA DE Desktop Client is unable to connect to DE server.

Environment

CA Workload Automation DE: Any
OS: Any

Cause

The Desktop Client requires several ports to complete the connection between client and server.

Resolution

DE has four ports that are used for client and agent connections.  These ports must be opened for the client and agent to be able to connect.  

Open the following default ports from Desktop client machine to dSeries (DE) server:

7500
7507
7598
7599

Note: If different service ports are were used during install, thenthey may be obtained from the tracelog in the logs directory.

For Linux/UNIX, run the following grep commands to list the ports used by DE server.

grep "CA WA Server RMI" tracelog.txt 
(Instance) rmi.export.port=7598 : CA WA Server RMI Export Port
(Instance) rmi.registry.port=7599 : CA WA Server RMI Registry Port

grep "CA WA Server Manager Port" tracelog.txt 
(Instance) manager.inputport=7507 : CA WA Server Manager Port

grep "CA WA Desktop Client Port" tracelog.txt 
(Instance) clientsession.listenport=7500 : CA WA Desktop Client Port

For Windows, use the findstr command to get the ports from tracelog.

findstr /C:"CA WA Server RMI" tracelog.txt

findstr /C:"CA WA Server Manager Port" tracelog.txt
findstr /C:"CA WA Desktop Client Port" tracelog.txt
