In Response To: Re: Informix platform migration advice needed (Eric Rowell)

Thanks Eric.

I have over 900 tables in each database, in 6 databases. Most of my
DB's are between 3-5 Gigabytes each. The databases are exactly alike
because we have 5 Undergraduate colleges and 1 Graduate college with
their own ERP database, and we share the ERP application between the 6
institutions. The one database has about 40Gb because of all the
meticulous transaction auditing done by one of the colleges. The
problem that I'm running into is all of the views that point to each of
the databases, dbimport bombs because the SQL statement creating the
view to a table in a database that hasn't yet been imported. So, the
import dies before completing.

I though of editing the dbimport SQL script and plucking out all the
create view commands, and putting them in a separate SQL script after
each of the 6 databases have loaded their table data. But that's a lot
of work.

Thanks again Eric for any best practice advice.

Sincerely,

Jonathan Smaby

I'm not sure why you had so much trouble with dbexport/dbimport since
the
files are text. How where the files transfered between the two systems?
Are there pk/fk relationships that could be messing with the dbexport?

I have heard great things about Art's Programs but haven't used them.

How big is this database? Is it worth just scripting it out using
"unload"
for the first test?

As for the backup tools being used... Sorry out of luck there.

Good Luck,

Eric B. Rowell
