I am attempting to isolate the identification attributes of an individual block. Prior to multitenant, this was easy to do using the RDBA to get the file and block. However, in a PDB, the RDBA does not tell me how the root container identifies the block either by the file number at the root level or by the container ID.

I've done a lot of digging and debugging and can't figure out how the root container identifies a block or where it might be in the block header. Any help would be appreciated.
