Isn’t that a nice error message:
Tue Jan 22 05:47:15 2008
Propagation Schedule for (AFC999DDA45.LAJK, AFC999DDA45_REMOTEDB) encountered following error:
ORA-00000: normal, successful completion
You can find such error messages in your alert log followed by an ORA-600 (internal error).
And of course it helps you a lot! 😉 But fortunately the propagation name is also written out. So you have at least one evidence.
