Re: Error: dbspace chunk

To initialize Informix you must be user informix and the environment variables must be correct. Please refer to my responses below.

If not, how do I determine the correct value? Basically you can have the same values for DBSERVERNAME and INFORMIXSERVER. Why are you using /etc/profile? > > > 2. The Rootdbs!

Remember in Unix that directory permissions have an impact on what you can do with the files under that directory even if you have all the permission for a file. You'd be better off for now to create the files in the INFORMIXDIR directory, that is if this directory has the correct permissions for informix. And then change the ROOTPATHto point to that file. > > > 3. What is the minimum size of a rootdbs? The minimum size is dependent on several factors the size of your physical log, logical log, number of logical logs, plus system tables. If your using the defaults I would probably stick with 100 MB to be safe. > > > Thank you all for your responses > > Jerry.
