Thanks - I had not noticed the "deleteActions" in the docs I had found.

I used their example as a template.  If I attempt to display all the completed actions, the JVM will core. :-(

I am an absolute beginner with Python/Perl/etc.. (I decided to be sysadmin and not a developer for a reason ;-)

The example below will work, but if I attempt to use the section now commented out, it will fail.  I will probably need to open a case and ask them how to run sql against the DB to clear out the entries.

#!/usr/bin/env python
import xmlrpclib

SATELLITE_URL = "http://rhnsat01.corp.company.com/rpc/api"
SATELLITE_LOGIN = "satadmin"
SATELLITE_PASSWORD = "password"

client = xmlrpclib.Server(SATELLITE_URL, verbose=0)

key = client.auth.login(SATELLITE_LOGIN, SATELLITE_PASSWORD)

# CHANGE THINGS AFTER THIS LINE
list = client.schedule.listArchivedActions(key)
for record in list:
   print record.get('id')

#list = client.schedule.listCompletedActions(key)
#for record in list:
#  print record.get('id')
  #client.schedule.cancelActions(list)

# CHANGE THINGS BEFORE THIS LINE
client.auth.logout(key)

Thanks again for your assistance and advice.

I modified the approach (slightly).  If I was to build an array with all 116,000 actions, or attempt to, using the entire stack - it would still create a JVM core. 

So, I did the following:

#!/usr/bin/env python
import xmlrpclib
import time

SATELLITE_URL = "http://XXX/rpc/api"
SATELLITE_LOGIN = "XXX"
SATELLITE_PASSWORD = "XXX"client = xmlrpclib.Server(SATELLITE_URL, verbose=0)

key = client.auth.login(SATELLITE_LOGIN, SATELLITE_PASSWORD)
