Answer:
Hi !

Well, the informix way would be a

onspaces -d ccm -p /ccmchunk/ifmx01_ccm_4.dbs -o 0

Then the chunk file should be disconnected from the informix
body and rm does the rest.

Informix will only allow to do that, if the chunk is "clean" and
removel of the chunk will not mess up db integrity.

What I do not know exactly is, if there is any CM stuff, who tries
to control the informix things, too.
I will check it in my poor test environment

Regards,

Mert

To the best of my knowledge ccmsrv expand is not reversible. Your best bet is to ensure all databases are backed up then do a ccmsrv delete followed by ccmsrv create to put you back where you were.

Hi Guys,

Thank for the help


Hi Mert Vuraldi,

Yes the command work. Thank for the help.

setting the environments....
INFORMIXDIR, INFORMIXSERVER, and PATH to point to the correct installation.
The command syntax is....
onspaces -d ccm -p /ccmchunk/ifmx01_ccm_4.dbs -o 0
Most important make sure the chunk is empty. Run onstat -D to confirm.
