Drop DBSpace

Posted By: Marcus Haarmann
Date: Friday, 14 October 2011, at 11:02 a.m.

Hi experts,

I want wo drop a dbspace, which we have been using for some byte columns
as blob store.
Now, we added a smartblob space and copied all the values to a blob
column.
The whole table was copied and access to the new table works good.
Old table was dropped now.
We want to free the space for the BLOB dbspace now.
Following situation:
onstat -d update

IBM Informix Dynamic Server Version 11.70.FC3GE -- On-Line -- Up 7 days

So, according to oncheck, only some internal pages are used.

onspaces -d blobdbs
WARNING: Dropping a BLOBspace.
Do you really want to continue? (y/n)y
Cannot drop the Space.
ISAM error: DBspace is not empty

Any idea what to do ? (By the way, Linux 64 bit, Debian 6.0 Ifx
