Oracle 19c pdb open restricted 处理

Oracle 19c pdb open restricted 处理

在CDB下查询受限的PDB：
set lines 200 pages 50000;
col name for a20;
select con_id, name, open_mode, restricted from v$pdbs;

在PDB中查询相关受限的PDB：
select instance_name, logins, status from gv$instance; (v$containers也可以查询)

cdb下更换 pdb restricted 模式：
alter pluggable database pdb_name close immediate instance=all; (all except pdb1)
alter pluggable database pdb_name open read write instance=all;

alter pluggable database PDB$SEED close immediate;
alter pluggable database PDB$SEED open read write;

pdb下更换 pdb restricted 模式：
alter session set container=pdb_name;
alter pluggable database close immediate;
alter pluggable database open;

在受限模式下，可以授予特定用户 restricted session权限用于临时登录，记得revoke。

alter pluggable database pdb_name open read only;
alter pluggable database pdb_name open upgrade;
alter pluggable database pdb_name open read write;
