Re: reliability?

by "Kevin Cherkauer" <invalid_address@[EMAIL PROTECTED] > May 7, 2008 at 01:31 PM

I just tried this on recent builds of the next-to-be-released 10.00, 11.10,

and 11.50 versions (currently these are numbered 10.00.xC9, 11.10.xC2W3, 
11.50.xC2; of course these numbers might change and my posting this is no 
guarantee from IBM that these will necessarily be released...), and it 
worked correctly on all of them. All of these were on 64-bit x86 Linux.
The 
same query also worked against a regular table on all of them. (sysmaster 
tables are not normal tables -- they are what we call pseudotables. The
code 
to access them produces them out of thin air, or rather out of the
contents 
of memory on the fly, so it's possible for some things to be broken for 
particular sysmaster tables that work correctly for other sysmaster tables

and normal tables.)

This has the flavor of a bug that has already been found and fixed in
later 
fixpacks. I will ask the optimizer team if they know of any such fix
having 
been done.
