If you still have problems contact Rational Customer Support. This document is divided up into two sections. General introduction discussing what happens when the Synergy session starts. A list of commonly seen problems (and some not so commonly seen) and possible solutions. Information about 'ccm start' command In order to start a Synergy session in a distributed installation, several different Synergy processes need to consistently identify which host they are on, find each other, and successfully communicate. In order to make the later sections clearer, let’s first introduce the main processes involved in starting a session. In broad terms the relevant Synergy processes are as follows: UI: a session's user interface process. This can be a Graphical UI or Command Line Interface session Engine: a session's engine process sqlexecd: database server network daemon. (Relevant for release 4.5 Servers on UNIX only, It is obsolete since release 5.0) Objreg: object registrar daemon Router: router daemon/ service ESD: engine startup daemon (optional).(Relevant for release 6.2 and newer) In addition, we will make r

To enable x forwarding, you have two ways: with the openssh package of Cygwin with putty 3.1 - With openssh Make sure you have the openssh package installed. Launch Cygwin/X In an X terminal, you can run the following in an X terminal: $ ssh -Y username@remote_hostname_or_ip_address where the Y parameter enables trusted X11 forwarding.
