DB version: 12c till 19c
OS : Oracle Linux, RHEL 7.x
I am new to working in multitenant architecture.
As a DBA, when I want to do some admin tasks in a PDB, I connect to the root container as SYS first and then I issue the following command to 'connect' to the PDB.
alter session set container=pdb3;
I have done basic stuff like user management, adding datafile, etc after connecting to the PDB using the above mentioned ALTER SESSION SET CONTAINER method. It seems to be working fine. But, then again, I am new to working in a multi-tenant architecture.
Hence, I would like to know if there are any risks in following the above method, in any special circumstances.
