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

Issue/Introduction

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

Cause

The Desktop Client requires the RMI ports to complete the connection between client and server.
By default the DE RMI ports are 7598 and 7599.  They should be opened on the DE servers.

Environment

CA Workload Automation DE: Any
OS: Any

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. 

Note: If the service ports are not known then they 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
