I'm developing an app that requests data from an external Oracle DB via a WAN connection. The Oracle DB is SLOW to return the data. Depending on the data being requested, the response time varies from 3 minutes to 20 minutes. Here's an algorithm I'm planning on developing. I need suggestions with Step 3
Step 1 - Delete the local copy of the previous Oracle export file (tab-delimited).
Step 2 - Send request to Oracle server for new file (using BAT/CMD file combo).
Step 3 - Wait for 60 seconds.
Step 4 - Check for the presence of the new export file.
Step 5 - Is the file there? Advance to Step 6. If not, return to step 3.
Step 6 - Import the file.
