A couple of tables were set up for generating data to the target database. When attempting to use Datamaker, the application crashes as soon as it starts writing the data to target without giving any error.
TDM all supported releases
There was space in the Target connection name which was crashing Datamaker.
Correcting the name and removing the space character, resolved the issue.
Always double-check your connection profile values. Spaces have proven troublesome in the past on many occasions. The next is simple mis-spellings.
