SCHAPI table estimate_compression

Posted By: FRANK
Date: Thursday, 30 April 2015, at 10:55 a.m.

Folks,

IDS12.10 FC4, Redhat Linux

Just curious about the automatic " SCHAPI Estimate Compression..." info
in the online log.

Why did it estimate compression automatically? Really needed ?
Apparently, Informix does not compress tables automatically.

Thanks
Frank
