Just create the dbspaces in the duplicate db with same name and pointing to the same named chunks. Then in offline mode itself, copy the production db chucks to the duplicate db chunk location and overwrite them. Then try bringing the Informix online.
I tried the copying all the chunks in duplicate except for the one having sysmaster db, but on initializing, it gave sanity error. When I copied all the chunks, there was no error and it recongnized all the dbs as on the production system.
thanks for the suggestions. I have tried copying in the chunk files in various trials (sysmaster (rootdbs) appears to be the bad one) but I've not had any luck in being able to retrieve any data from the chunk file I need to. Informix complains about the new chunk and tries to right the ship. In some cases Informix does get back to a sane level but cannot read the chunk that doens't fit. Whne I try to look at our db, I get errors like:
Validating database jnic
ISAM error: TBLspace does not exist
I've looked at a couple of ways to relink but nothing has worked so far.
Again thanks for the suggestions. I realized from the beginning this might be a lost cause.
