The file README.TXT states that one should use the following commands to start/stop the Knowledge Center on non-Windows platforms:
> ./bin/startKC.sh > ./bin/stopKC.sh
Unfortunately, the files startKC.sh and stopKC;sh are not present in the subdirectory bin.
Is the beta documentation available online?
The question is being forwarded to Db2 Documentation team and awaiting their input.
