Chunk Not empty
Posted in 2005
Topics: Storage & Space Management, Server Administration
Hi,
I am trying to drop a dbspace (named conversion). That dbspace originally was
consisted from 10 chunks (conv_dat.000 to conv_dat.009). I have dropped
successfully up to conv_dat.005 chunk.
When I try to drop conv_dat.004 chunk
(using the onspaces -d conversion -p E:\\\\IFMXDATA\\\\ol_prime\\\\conv_dat.004 -o 0 -y
command)
I get the following error message
' Chunk conv_dat.004 can't be dropped (Chunk is not empty)'
Giving the oncheck -pe command and isolating the refercnces about the
conversion dbspace I get the following output:

It seems that something occupies (conversion:'informix'.TBLSpace) 50 pages
from the chunk BUT I don't know what.
Before start dropping chunks I have dropped all the tables on the conversion
dbspace using a script that the table creator give to me in order to delete
them.
Any advices?
Thanks in Advance

Hi
Sergios,
those 50 pages are tblspacetblspace pages, there was a
bug where the drop didn't work as the chunk contains
tblspace extended pages even when the chunk has no
user table pages. I think this is your problem.
The best thing to do is open a case with tech support
they will be able to drop that chunk and also will
tell you what IDS version has a fix for this problem.
Regards
esteban.-
