Introduction
The Client Application Protocol (CAP) interface has been removed from Release 22.0. CAP is no longer supported in 22.0 and up and thus this must be disabled post upgrade to 22.0 to prevent connection attempt and OCS errors, illustrated by alarms such as “A CAP connection has been terminated between the Open Client Server and Application Server 1.2.3.4” or bwOpenClientServerASConnFailed".
After upgrading the Application Server and Xtended Services Platform to 22.0 there may be CAP alarms displayed on both the AS and XSP.

Resolution
Disable the CAPProxy on all deployed servers as this is no longer supported in 22.0. It is recommended to do this in the same maintenance window as the upgrade.
XSP_CLI/Applications/OpenClientServer/CAPProxy> get
enabled = true
serverPort = 2206
numConnections = 1
XSP_CLI/Applications/OpenClientServer/CAPProxy> set enabled false
*** Warning: BroadWorks needs to be restarted for the changes to take effect ***
After the change has been applied the server will require OpenClientServer to be restarted. If CAPProxy is disabled prior to the upgrade OpenClientServer does not need to be restarted as it will be restarted during the upgrade.
$ restartbw OpenClientServer
