由ORA-01502: index 'SYS.I_DEPENDENCY1'导致的ORA-01092

想做个AWR报告,结果提示SQL_ID但是我出的是普通报告没有针对某个SQL，就退出了。退出后不能连接Oracle，打开其他之前连接的session想重启，immediate不行错误如下
SQL> shutdown immediate
ORA-24324: service handle not initialized
ORA-01041: internal error. hostdef extension doesn't exist
就用了abort。重启后还是不能open，重启Linux后还是不能open。报告

ORA-01092 ORACLE instance terminated. Disconnection forced  
Cause :The instance connected to was terminated abnormally, probably due to a SHUTDOWN ABORT. The current process was forced to disconnect from the instance.  
Action :Contact the database administrator to determine when the instance is restarted. Attempt to reconnect after the instance is running again.

idle> startup nomount
ORACLE instance started.
idle> alter database mount;
Database altered.
idle> alter database open;
alter database open

ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced

 

检查alert检查trc结果如下

幸好只是个测试库，要是生产就疯了，问题是我没有动系统的任何视图啊，怎么会出现这个错误？

随后查看alter还是一样的错误，然后试图关闭

又回到了最初的错误。找到了从linux平台killoracle进程的方法
终止与ORACLE_SID有关的所有Oracle过程。
用ipcs –pmb命令来识别所有占用的RAM内存片断。
用ipcrm -m 命令来从UNIX中释放占用的RAM内存。
只对Non-AIX：用ipcs -sa命令来显示占用标记，用ipcrm –s命令来释放该实例的占用标记。
创建单一命令来终止与挂起（hung）的数据库实例有关的Oracle过程是很简单的。在下面的例子之中，我们用ps指令来识别Oracle过程，然后用 awk程序来获取Oracle过程的过程ID（process ID，PID）。然后，我们把过程ID输入到UNIX的kill命令之中。
root> ps -ef|grep $ORACLE_SID| grep -v grep|awk '{print $2}'|xargs -i kill -9 {}   
在终止所有Oracle过程之后，我们可以用ipcs –pmb指令来检查占用的内存并清除数据库所占用的内存。我们首先显示出数据库服务器上所有占用内存：
root> ipcs -pmb
IPC status from /dev/kmem as of Mon Sep 10 16:45:16 2001
T      ID     KEY        MODE     OWNER  GROUP  SEGSZ  CPID  LPID

m   24064 0x4cb0be18 --rw-r----- oracle    dba 28975104  1836 23847
m       1 0x4e040002 --rw-rw-rw-   root   root    31008   572   572
m       2 0x411ca945 --rw-rw-rw-   root   root     8192   572   584
m    4611 0x0c6629c9 --rw-r-----   root   root  7216716  1346 23981
m       4 0x06347849 --rw-rw-rw-   root   root    77384  1346  1361
在这里，我们看到Oracle只拥有一个ID=24064的RAM内存。下面的命令将会释放这个内存片断：
root> ipcrm -m 24064

2.建立表空间然后exp/imp
oracle-> exp sys file=/tmp/etmcdb.dmp log=/tmp/etmcdb.dmp full=y BUFFER=64000

3.RMAN异地异机恢复

3.1 全库恢复-错误肯定还是一样，因为sys试图丢失了，就当练习了，做一遍
先将DBID设置的和生产库一样
RMAN>set DBID=12345678
RMAN>connect target /;
RMAN>startup force nomount;
RMAN>restore controlfile from  ‘/u02/oradump//SCMDB/backup/current/XXX.controlfile.XXX’;
RMAN>alter database mount;
RMAN>restore database (这里注意空间问题，回滚段需要很多空间)
RMAN>recover database using controlfile until cancel;(这里的不完全恢复根据实际情况确定)
这里可能会报错，没关系，你看日志号完全应用完了就可以了，继续往下做。
RMAN>alter database open resetlogs;

3.2 单表空间恢复

直接把表空间下的两个DBF考回
SQL> startup

Total System Global Area 1073741824 bytes
Fixed Size                  1223540 bytes
Variable Size             662701196 bytes

ORA-01110: data file 4: '/u01/oradata/ETMCDB/ETMCDB_data.dbf'

目前还没有找到好的恢复方法，RMAN单独表空间恢复？
