If SharePlex is installed on any port other than the default of 2100, use the -p option to specify the port number.
ora_cleansp should be with -r option.
To run ora_setup with default port: 2100
On OS command prompt, cd to full path of the SharePlex bin subdirectory.
To run ora_setup with non-default port: 9000 (as example)
Make sure that the ORACLE_HOME and ORACLE_SID is set in the windows environment variable before starting sp_cop service.
c:\ ora_cleansp <DB username>/<password> -r<port>
NOTE: Make sure the vardir path prompted is for the port mentioned in the ora_cleansp command.
