Chunk Size Questions

Posted in 2003

Summary

Geezer From The Freezer asked what units the size and free columns in the onstat chunk listing use. Neil Truby replied they are pages, while the utilities that create chunks take sizes in KB. Fernando Nunes added that the engine reports in pages, normally 2KB on Unix. Solved.

How big are the actual sizes supposed to be?

You need to go on a course, or RTFM a bit more, don't you?! The quantities given are in pages. Confusingly, the utilities you use to create the chunks require you specify the sizes in kbytes. -- Neil Truby t:01932 724027 Director m:07798 811708 Ardenta Limited e:neil.truby@ardenta.com "Geezer From The Freezer" <Geezer@Freezer.com> wrote in message news:3F3B930F.8D70E12A@Freezer.com... > > How big are the actual sizes supposed to be? > Doesn't say if it's bytes, KBytes or anything > > > Chunks > address chk/dbs offset size free bpages flags pathname > 17a2a790 2 1 0 1024000 967901 PO- /telelogic/DATA/DATA2 > 17a2b830 2 1 0 1024000 0 MO- /informix/rootdbs2.mir > 17a2b3d0 16 2 0 250000 3 PO- /informix/disk2-a-5 > 17a53710 16 2 0 250000 0 MO- /informix/disk2-b-5
