Oracle Database 12c: What happens during CDB startup if one the PDB has a media problem? - Continue

During Oracle Day 2014  (February 05, 2014, which was held in Baku/Azerbaijan), I met with my friends and had a conversation about several topics. I asked to my friend Teymur Hajiyev, what happens during CDB startup if one the PDB has a media problem? He said, CDB must open without a problem. But you need to open PDBs manually. In other words, by default PDBs in mount mode, you need call alter pluggable databases all open. After Oracle Day, Teymur shared his tests in here.  and faced the same issue. But he is wrote : If you apply PSU1 on 12c, you will not meet with such problem, CDB will skip opening problematic PDB and will open other PDBs. I will share my tests on patched database. I applied PSU1 to my database server:   Installation and configuration Patch 17552800 - 12.1.0.1.2 Patch Set Update My test environment as below: [oracle@oel62-ora12c /]$ export ORACLE_SID=prmcdb [oracle@oel62-ora12c /]$ sqlplus / as sysdba SQL*Plus: Release 12.1.0.1.0 Production on Wed Feb 1
