We recently had an experience on an Oracle Autonomous Database where our production instance started giving us lots of errors saying:
ORA-20001: You have exceeded the maximum number of web service requests per workspace. Please contact your administrator.
After some investigation, I found a couple of interesting blog posts by Dimitri Gielis and Scott Wesley that seemed to address this exact issue.
However, on the Autonomous DB these pages are not available. So the questions become: Can we change this parameter? and if so, how and where?
To view the current value of MAX_WEBSERVICE_REQUESTS, we can execute the following query that uses the get_parameter function.
