Increasing Maximum Web Service Requests in Oracle APEX 18.1

While running our final tests of APEX Office Print (AOP) 18.1 we hit "ORA-20000: Issue calling Main AOP Service (REST call: ): ORA-20001: You have exceeded the maximum number of web service requests per workspace."

When you login into the Internal Workspace and navigate to a workspace, there's a setting for  Maximum Web Service Requests. The default value is 1000 requests per 24h (rolling window).

If you know that AOP has next to hundreds of server tests, also around 500 automated tests through APEX, we hit this limit after the second full run. After setting the value to 20000, we are able to continue our final testing :)

I guess the chances are small you will hit the limit in a normal APEX app, but if you do, it's easy to fix by setting a higher value for your workspace.
