By default the copy uses port 2501. But this may not always be allowable, if another process is using that port or if there is a firewall environment that only has selected ports open for use by programs like copy. This solution delves on way to use alternate port for copy other than the default port 2501.
General information.
You can launch copy on a different port as below:
On source
sp_ctrl>set param SP_OSY_PORT <port #>
On target
sp_cvtrl>stop launcher
sp_ctrl>set param SP_OSY_PORT <port #>
sp_ctrl >start launcher
Then run copy from source. Henceforth it will use the port specified by the parameter SP_OSY_PORT until it is changed again. Do not use the port # currently used by this Shareplex instance.
