Use of staticCreatePrototypeResource method during Resource configuration

Question

Does anyone know when the staticCreatePrototypeResource method of an adapter is called? I am trying to create a custom adapter that accepts various different modules to actually do the provisioning. The problem I am having is making the prototypeXML dynamic.
I know that the prototypeXML is used to store the resource in the repository. I assumed during a creation that the prototypeXML was obtained and populated upon submission of the Resource Wizard form. However, I have put some trace with my custom adapter and that does not seem to be the case.
Instead the staticCreatePrototypeResource method seems to only get called once, upon the first load of the Resource web page. The xml must then be cached someplace and used during the creation process. I am trying to determine if there is any way around this.
Thanks,
Pete

I wouldn't kill the Presentation Services as it might look like the system is down which is not true. A possible way could be to use a repository variable. We use this method to prevent users from seeing new data as our ETL process is loading it. You could have a repository variable called batchrunning. You would then have an Init Block that refreshes this variable every 5 minutes or so. The Init Block could select a value from a table where you store the status of your batch. Then you would add this variable to all facts as a filter in the RPD like this: where batchrunning = 0. When you are updating the DB you would first change the value on your status table to 1. Once the variable is refreshed all new queries will fail since batchrunning is not equal to 0. Once the ETL process is finished, you would set the status table back to 0, the BI Server would refresh the variable and all the queries will start to work again.
If you prefer to shutdown services then I suggest you shutdown the BI Server as at least the users will be able to get to the Web Server and it won't look that bad.
