转贴：ORA-01034 ORA-27121 错误
ORA-01034: ORACLE not availableORA-27121: unable to determine size of shared memory segment
Linux Error: 13: Permission denied
主要是因为oracle安装程序没有给oracle这个可执行程序设置正确的setuid。这样设置一下：
$ cd $ORACLE_HOME/bin
$ chmod 6751 oracle
结果类似这样就行了。
$ ls -l $ORACLE_HOME/bin/oracle
-rwsr-s--x 1 oracle oinstall 23352783 Aug 14 2001 /home/oracle/app/oracle/product/8.1.6/bin/oracle

装两个数据库
db1
和
db2,
分别有两个用户
db1user
和
db2user
，分别属于
ORADBA1,ORADBA2,
共同属于
oragroup
安装组。装好两个库后出现如下错误
现象
SQL> connect db2user/db2user@db2
ERROR:
ORA-01034: ORACLE not available

此时
$ ls -alt $ORACLE_HOME/bin/oracle

-rwsrwsrwx 1 oracle1 oragroup 77765688 Sep 7 16:00 /usr/sap3/oracle/product/920/bin/oracle
（原权限是
6751
）
如果把
/usr/sap3/oracle/product/920/bin/oracle
的所有者改成
oracle2
则可以启动
DB2
，但是
DB1
却出现同样错误，无法连接。于是判断是某个文件的权限不对。于是一步一步检查。
看谁拥有内存

没看出什么明显问题。
首先设置
UMAKS 000
在设置
/var/opt/oracle/oratab
为
DB1:/usr/sap3/oracle/product/920:Y
DB2:/usr/sap3/oracle/product/920:Y
再
chown -R oracle1:oragroup $ORACLE_BASE
chmod -R 777 $ORACLE_BASE
chmod 6777 $ORACLE_HOME/bin/oracle
