UPDATE GLOBAL_NAME SET GLOBAL_NAME = '';注意：生产环境不要随便执行哦，特别是像我这种小白！
如果把GLOBAL_NAME 修改为空的，或者存取GLOBAL_NAME的数据块发生损坏就会报[18062]的错误，如下
SQL> startup
ORACLE instance started.
Total System Global Area 422670336 bytes
Fixed Size 1344616 bytes
Variable Size 318770072 bytes
Database Buffers 96468992 bytes
Redo Buffers 6086656 bytes
Database mounted.
ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-00600: internal error code, arguments: [18062], [], [], [], [], [], [], [],
[], [], [], []

模拟实验
1.查看global_name的值
SQL> select * from global_name;
GLOBAL_NAME
--------------------------------------------------------------------------------
NODE3
2.把 global_name 值做修改
SQL> UPDATE GLOBAL_NAME SET GLOBAL_NAME = '';
1 row updated.
SQL> commit;
Commit complete.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.

二、解决方法：
1) 启动数据库到 Mount状态
SQL> conn / as sysdba
Connected to an idle instance.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 422670336 bytes
Fixed Size 1344616 bytes
Variable Size 318770072 bytes
Database Buffers 96468992 bytes
Redo Buffers 6086656 bytes
Database mounted.
2) 查找oracle进程的pid
[root@node3 ~]# ps -ef | grep LOCAL | grep -v grep
oracle 2562 2517 0 15:09 ? 00:00:00 oraclenode3 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
2562
3)这个 PID是 2562 是下面要使用的GDB
[root@node3 ~]# gdb $ORACLE_HOME/bin/oracle 2562

(gdb) break kokiasg
Breakpoint 1 at 0x14d5f20
(gdb) continue
Continuing.
这一步会一直停在这里
6) 打开一个新的窗口打开数据库
SQL> alter database open
这一步会hang住不动
这时候gdb会输出以下内容
Breakpoint 1, 0x00000000014d5f20 in kokiasg ()
7) 打开一个新的窗口，用sqlplus登录
SQLPLUS / as sysdba
SQL> select status from v$instance;
STATUS
-----------
OPEN
SQL > update global_name set global_name = 'NODE3';
1 row updated.
SQL > commit;
8)打开一个新的会话，连接到sqlplus查看GLOBAL_NAME:
SQL> select * from global_name;
GLOBAL_NAME
----------------------
NODE3
9) Kill GDB 的会话然后退出
(Gdb) kill
Kill the program being debugged? (y or n) y
(Gdb) quit
重启数据库成功
SQL> startup
ORACLE instance started.
Total System Global Area 839282688 bytes
Fixed Size
Variable Size
Database Buffers
Redo Buffers
Database mounted.
Database opened.
这个时候最开始hang住的会话会看到如下错误
alter database open
