Oracle 12c中如何自動啟動PDB Pluggable Database

PDB Pluggable Database是12c的一個重要的新特性, 但是對於CDB中的PDB,預設啟動CDB時不會將所有的PDB帶起來,這樣我們就需要手動alter pluggable database ALL OPEN;

[Oracle@clouds ~]$ sqlplus "/as sysdba"

SQL*Plus: Release 12.1.0.2.0 Production on 星期四 3月 31 08:52:31 2016

串連到:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Partitioning, Automatic Storage Management, OLAP, Advanced Analytics
and Real Application Testing options

SQL> select open_mode from v$database;

OPEN_MODE
--------------------
READ WRITE

SQL> alter pluggable database bidb1 open;

插接式資料庫已變更。

SQL> alter pluggable database bidb2 open;   

插接式資料庫已變更。

SQL> select con_id,name,open_mode from v$pdbs;

    CON_ID NAME                          OPEN_MODE
---------- ------------------------------ ----------
        2 PDB$SEED                      READ ONLY
        3 BIDB1                          READ WRITE
        4 BIDB2                          READ WRITE

--或是直接啟動所有pluggable資料庫

SQL> alter pluggable database all open;

可以通過添加Trigger的形式來定製化startup時自動將PDB OPEN

使用SYS使用者建立如下觸發器即可:
CREATE TRIGGER open_all_pdbs
  AFTER STARTUP
  ON DATABASE
BEGIN
  EXECUTE IMMEDIATE 'alter pluggable database all open';
END open_all_pdbs;
/

這樣,在oracle 12c database 的cdb啟動後,pdb也會自動啟動了。
