Oracle - 10.2.0.4 OS - SUSE10 Platform - IBM zSeries mainframe The decision was made recently to install the 11g R2 client on our application servers. I installed it, set up the tnsnames and tested connections to all databases using SQL*Plus. No problems at any step. Problems arose when they couldn't start the application using the thick client, only the thin client. Due to the way our application was written, the thin client allows non-printable characters into the tables that the application cannot then pull back out. They chose to ignore my advice that they thoroughly test and verify what was being affected. Customers are complaining about "corrupted" data. The word I get is "we don't have time to fix the app, fix oracle." Many people at the company are under the impression that 11g R2 client is strictly a thin client. Is that true? How do you determine that? -- Sandy Transzap, Inc.
