Re: Create 12c or 18c database in traditional architecture

Hey,

agreed, these are annoyances and we try to capture as much as possible in our s/lrgs. Clearly we missed this. This should work when executed in the context of PDB. I didn’t see any bugs logged against this, so I’ve filed bug 28571259 and routed it to the code owner for follow up.

As an FYI, both short and large regressions are run in a Multitenant in both single tenant and multitenant topologies. We still run a small number of regressions against non-CDBs.

thanks,
jpm

So it is not only the application and the DBA scripts that have to be tested. The whole tools covering the whole development life-cycle as well.
