Patched IB DataPump
IB DataPump is an old and very known utility from CleverComponents used to pump data from several source databases to IB/FB databases. Unfortunately, it isn’t updatet from a long time and has a problem with Firebird 3 servers. A few months ago, it became Open Source, so it was possible to fix this problem.
Norbert Saint Georges was kind enough to compile a new version with the fix and provide a download link at tetrasys.fi/data/ibpump.7z
