It said that the single data file is split into chunks, the chunks are distributed among various file servers, and the application might modify one or more (but not necessarily all) of the chunks, meaning that each chunk might have a different modification date/time. The system will then base its decision on deleting the complete file by figuring out the most recent modification date/time among all the chunks of the file, across all the relevant servers, and comparing that with the time-to-live value. It's not a simple expiration date on one file located in one location, but a more complex network-oriented operation. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
