Adding a Chunk

Posted in 2007

Summary

joe.connolly asked whether the offset when adding a chunk to a raw device is in pages or kilobytes. Dale Gilbert, Keith Simmons and Martin Fuerderer all answered kilobytes. Martin gave the rule: input to commands and onconfig is in kilobytes, while output such as onstat is in pages. Solved.

I was wondering, when you add a chunk to a dbspace that is already using part of the raw device and need to specify an offset is the offset expressed in pages or kilobytes? Thanks

The rule of thumb is: when talking to the OS use KB when talking to the engine use pages. So use KB when adding a chunk -----Original Message----- From: informix-list-bounces@iiug.org [mailto:informix-list-bounces@iiug.org] On Behalf Of joe.connolly@gmail.com Sent: Thursday, April 19, 2007 7:31 AM To: informix-list@iiug.org Subject: Adding a Chunk I was wondering, when you add a chunk to a dbspace that is already using part of the raw device and need to specify an offset is the offset expressed in pages or kilobytes?

Hi, kilobytes. The general rule is: - input is in kilobytes (for commands and in onconfig file), - output (e.g. onstat) is in pages.
