Hi, How to Change sysdistrib tables extent size during creation of a database or instance itself? FYI.Checked already sysmaster.sql.
VERSION INFORMATION!!!! In the latest versions of IDS 11.50 you can set the default extents for the engine in the ONCONFIG file then when you create the database the catalog tables will have larger extents. Art Art S.

You can change the next exent size anytime, either immediately after the database is created or anytime thereafter. Take care.

Yeap, but it will only obey the new sizes after table re-creation, like the manuals says, right? There´s not a "on-the-fly" way to do it, unless rebuilding the entire table, I read. Regards.

NEXT SIZE takes effect immediately but only affects new extents, so, if you already have stats in the database for 10000 columns and you drop the distributions and recreate them, if the table is fragmented it will stay that way, yes, but if you create a new database with no distributions yet (or are about to add distributions for many new tables so that new extents are likely) then setting NEXT SIZE larger will help prevent new fragmentation of the table. I don't remember if you are permitted to use the new 11.50 reorg features on catalog tables, and you didn't post your version info 8-(, but it may be worth a try if you have a later release of 11.50 to reorg sysdistrib to get it down to one or two extents.
