What’s new with Oracle database 12.1.0.2.190416 versus 12.1.0.2.190716

There are a couple of undocumented spare parameters changed to named undocumented parameters, this is quite normal to see.

With the Oracle database version 12.1.0.2.190416 patched to 12.1.0.2.190716 on linux, the following things have changed:

And here are the differences in symbols (c functions).

The most notable thing to see are:
– almost no functions removed, it is normal to see a bigger number of functions to vanish.
– quite a lot of functions that are added are related to krsr*, kernel redo standby/dataguard remote file server.
– version 12.2 up to version 19 has had an addition of a huge amount of functions related to little cms, but it seems version 12.1 did not get this addition.
