一个Oracle Application Container的示例
2023-12-13 03:39:51
本例基本涵盖了Oracle Multitenant功能中application container的以下内容:
- 创建application container/root
- 创建application PDB
- 创建application SEED
- 在application root中安装application
- 在application root中升级application
- 同步application
整个过程如下
创建application container/root
create pluggable database app1_root as application container
admin user admin identified by Welcome1
roles=(connect);
alter session set container=app1_root;
alter pluggable database open;
创建两个application PDB:
create pluggable database app1_pdb1
admin user admin identified by Welcome1
roles=(connect);
alter pluggable database app1_pdb1 open;
create pluggable database app1_pdb2
admin user admin identified by Welcome1
roles=(connect);
alter pluggable database app1_pdb2 open;
创建application SEED:
create pluggable database as seed
admin user admin identified by Welcome1;
alter pluggable database app1_root$seed open;
alter pluggable database app1_root$seed close immediate;
alter pluggable database app1_root$seed open read only;
安装application,版本1.0:
alter session set container=app1_root;
alter pluggable database application APP1_USER_APP begin install '1.0';
create user user1 identified by Welcome1 container=all;
alter pluggable database application APP1_USER_APP end install '1.0';
两个application PDB与application root同步应用:
alter session set container=app1_pdb1;
alter pluggable database application APP1_USER_APP sync;
alter session set container=app1_pdb2;
alter pluggable database application APP1_USER_APP sync;
升级应用到2.0:
alter session set container=app1_root;
alter pluggable database application APP1_USER_APP begin upgrade '1.0' to '2.0';
grant create session to user1;
alter pluggable database application APP1_USER_APP end upgrade to '2.0';
其中一个application PDB与application root同步应用:
alter session set container=app1_pdb1;
alter pluggable database application APP1_USER_APP sync;
测试:
SQL> connect user1/Welcome1@//localhost/app1_root
Connected.
SQL> connect user1/Welcome1@//localhost/app1_pdb1
Connected.
SQL> connect user1/Welcome1@//localhost/app1_pdb2
ERROR:
ORA-01045: user USER1 lacks CREATE SESSION privilege; logon denied
可以看到,只有同步了应用的PDB具有连接权限。
