[comp.databases] Bugs in Oracle 6.0.x constraints on VMS 5.1

When migrating from 6.0.28 to 6.0.29 we discovered a bug in Oracle's
handling of multi-line constraints under VMS in export/import files.

If your constraint clause extends over multiple lines, the exported
file can't be imported.  The export file contains a '\n' in the
constraint confusing the import process.  Of course, we didn't dis-
cover the problem until *after* the tables had been destroyed to make
way for the re-imported data...

Oracle Technical Support was helpful in tracking down the problem, but
finding and repairing the bogus byte was tedious and laborious (you
never really think about how big a 100MB file is, until you have to sift
thru it...).

Oracle has escalated the problem but they estimate a fix is still at
least 1 month away.

If you need additional information, contact Oracle, or, you can
drop me a line.
