Re: Is there a maximum tape size for archives, logs?

Informix places a 2TB (terabyte) limit on archive tape size (at least for tbtape/ontape - can't remember what onarchive does). However, some OS flavors may cause problems with archives over 2GB in size. My understanding of the problem is that the OS counts the amount of data that is written between a single open and close of the tape device, and that when this value exceeds the limitations of the counter (2GB for a signed long, or possibly 4GB if they use unsigned long), the OS returns an error, which of course results in tbtape/ontape returning an error. Sorry, can't tell you which flavors of OS do what.
