Either you can build a new package with a command to remove the URL from the workstation, and assign it to the concerned workstations.
runchannel <URL of the channel> -remove
Or you can build a script to run the tuner commandline from a central location ( like the BBCA console server),for removing the concerned channel.
There are several methods to fix your issue.
- Subscription Policy
you can either delete the channel or use the updateFrom feature
- Tuner Profile
you can use the marimba.subscribe property with channel parameters
- Use Adil's suggestions
- Use a custom channel (requires Java programming) that uses the Tuner's public API to clean up
