ONUNLOAD, ONLOAD Questions

I am trying to use onunload to unload a 13 gig database to tape. We use the CA Unicenter tape management software and I receive errors whenever I try to write to a CA mounted tape. The error I receive is Informix error No 16 which says that the mount device is busy. In the Unix log I get the message: CAITAPED_F_0141000143 Not yours. I can successfully write to a CA mounted tape using ontape, dd and tar. I was able to write to tape using onunload at the database level when I totally took CA tape management out of the picture, but this is not a workable solution for our production environment. Second question: I am trying to copy the data from our database from one informix instance to a second instance on a separate test box. The database spans multiple dbspaces which consist of multiple chunks. Is there a way to direct the onload utility to put the tables in all the right dbspaces when onunloading and onloading at a database level? All I see in the documentation is an option to specify one dbspace for the database. The dbspace issue is even a problem if I want to onunload a database and later restore it to the same database. I really like to hear how others are using onunload / onload successfully to move fairly large databases across environments. S. Athey sathey@bepc.com
