Hi all, I'm writing an application that will process some real-time data I'm ingesting through LDM. This application will run around the clock in the cron, so it needs to be fairly robust. Here's my question - say I ingest a file via LDM. How do I know that file is complete? Does LDM place some sort of lock or other information on the file before it's completed writing? If my application tries to access a file that does not contain all the necessary data (a file that still has yet to be completely transmitted, for example), then I need to have my application not process the file. Does anyone else out there have experience with this? I know there's tricks you can perform, such as checking to see if the file has been modified in the past 30 seconds before opening, etc., etc., but I was just wondering if LDM actually places some sort of information with the file that says "hey, this file isn't done yet". Thanks for any help! Jason -- ---------------------------------------------------------------------------- Jason J.
