During this time, in order to provide customers with a perfect disaster, it has been testing 9i Data Guard,
Tested the way Logical LGWR, there are a lot of strange mistakes, so they replace it into the way of Physical LGWR, there are some unbelievable places in the middle, so they replace them with the most primitive Physical Arch. This method itself DataGuard has no problem, but there is a wait for CheckPoint Not Complete in the Alertlog of the Primary library. It can be seen that all live children will be handed over to the Arch process.
Fortunately, I solved the problems in Physical LGWR, so finally, it is a trick, but this time makes me a relatively good understanding of 9i Data Guard's configuration and application. It is also a good thing. A pile.
During this time, the problems and solutions of Data Guard have basically been written here, and it is a summary of a summary for their work.
Finally, I still have to say, I love Oracle DBA's work :)
