10g升级至11g后数据库无法启动的问题解决

今天升级数据库碰到一个很郁闷的问题，把10g的数据库升级到11g以后，结果有一个改动，需要重启数据库，就敲了shutdown immediate，结果再startup,数据库竟然起不来了。

$ORACLE_HOME,$ORACLE_SID等等变量都没有问题。

sqlplus / as sysdba

SQL> startup ORA-01012: not logged on

反复试了好几次，都是这样。这是准生产环境，汗马上就下来了。

1.sqlplus / as sysdba

SQL*Plus: Release 11.2.0.2.0 Production on Mon Sep 23 19:44:01 2013

Connected. ---这个登录信息貌似也少了点什么，

2.单纯敲sqlplus，直接报了ORA-01089的错误。

sqlplus

SQL*Plus: Release 11.2.0.2.0 Production on Mon Sep 23 19:44:30 2013

Enter user-name: system Enter password: ERROR: ORA-01089: immediate shutdown in progress - no operations are permitted Process ID: 0 Session ID: 0 Serial number: 0

3.通过nolog方式登录，结果一startup就开始报错了。。。。

> sqlplus /nolog

SQL*Plus: Release 11.2.0.2.0 Production on Mon Sep 23 19:47:26 2013

SQL> conn / as sysdba

Connected to an idle instance. SQL> startup ORA-01012: not logged on

4.最后再没办法了，只能startup force了。没想到这库一下子活过来了。

SQL> conn / as sysdba Connected to an idle instance. SQL> startup force ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance ORACLE instance started.

测试登录也正常，万幸万幸。

SQL> exit

----------------------------问题根源---------------------------

因为后续的操作，需要重启数据库，结果停了库之后，再启，竟然又出现了上面的情况

mos上说，

CAUSE

An orphaned shared memory segment belonging to the ORACLE_SID still exists from a previous instance startup.

我看没有其他的进程，只有监听还起着。

> ps -ef|grep PETAEM

oraaems1 28843 20949 0 09:00 pts/1 00:00:00 grep PETAEM

停了监听之后，启停就正常了。

> lsnrctl stop LISTENER_PETAEM1

其实关于ORA-01012的问题原因有很多，有的可能是Process不足，有的可能是有一些进程没关掉。
