Strange....    As a test can you replace your hard-coded toppic name with something like ${tableName} or just try a different hardcoded string and see if that gets you further along. Not saying that's a solution, but trying to eliminate causes.   Also, you mentioned you've implemented other flows already. Could it be that the topic name BUBB-MX_ALL_SOFT is already taken in your kafka cluster and thats why goldengate handler can't create the topic (though I would expect it to just write to the existing topic, instead of throwing an error).    I also found this on Oracle site that may have your answer. You'll need an Oracle account to look if there is a solution though. https://support.oracle.com/knowledge/Middleware/2512462_1.html   Could this also be an encoding or trailing character issue in the props file between Unix and AIX?   Overall this sounds like a GoldenGate error that may be better answered by Oracle community.     Regards, Alex ...
