I asked the DB2 dba to verify that the "schema.tablename" exists in the production database. He said that it did, and also that the production server is still running V7.1. The server is targeted to be upgraded this Sunday, so I'm wondering if the upgrade will resolve this problem.
The DBA also asked me if there was some way that I could verify what tables I can see on the Notes side. I've used the LSX Catalog method to take a look at tables and stored procedures in Sybase previously, so hopefully I can do the same with DB2.
