使用sid方式直接访问pdb(USE_SID_AS_SERVICE_LISTENER)

发表于 2025 年 2 月 17 日 由 惜分飞

有些应用,因为特殊原因,需要通过sid来访问数据库,在pdb环境中原则上都是通过服务名访问的,可以通过一定的监听配置实现使用pdb名的sid来访问该pdb
在pdb0中创建u_test用户并授权

ORA-00069: cannot acquire lock — table locks disabled for xxxx

ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-00069: cannot acquire lock -- table locks disabled for HR_XXX_01

关于ORA-00069错误解释

[oracle@xifenfei.com ~]$ oerr ora 00069
00069, 00000, "cannot acquire lock -- table locks disabled for %s"
// *Cause: A command was issued that tried to lock the table indicated in
//         the message. Examples of commands that can lock tables are:
//         LOCK TABLE, ALTER TABLE ... ADD (...), and so on.
// *Action: Use the ALTER TABLE ... ENABLE TABLE LOCK command, and retry
//          the command.

尝试lock表,直接hang,强制终止

SQL> alter table XFF.HR_XXX_01 enable table lock; 



^Calter table XFF.HR_XXX_01 enable table lock

HR_XXX_01                          246424 1073742359

发现报错表的flags和其他表不一样(其他表为1073742353,而报错表为1073742359),对于这种情况官方给出来的解决方法,关闭库,确保没有任何额外会话连接上来
ora-00069

因为本身要重启库维护,直接把库启动到upgrade模式进行操作
