六、利用dbca创建oracle数据库
Oracle用户下命令行输入dbca，弹出图形界面
A.注意需要选择asm存放
此处需要考虑到有的时候找不到dgroup1组，需要输入密码创建，总是提示spfile正在使用，此时可以采用关闭+ASM实例（shutdown immediate）,在重试就行了。
B. 注意字符集选择 ： Simplified Chinese ZHS15GBK # /oracle/oralnventory/orainstRoot.sh
# /oracle/product/10.2.0/db/root.sh
[root@L-DB-3-6 db_1]# cd /home/oracle/product/10.2.0/db_1/ [root@L-DB-3-6 db_1]# ./root.sh Running Oracle10 root.sh script...
The following environment variables are set as:
ORACLE_HOME= /home/oracle/product/10.2.0/db_1
Enter the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...
Creating /etc/oratab file...
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
[root@L-DB-3-6 db_1]# cd /home/oracle/oraInventory/ [root@L-DB-3-6 oraInventory]# ./orainstRoot.sh Changing permissions of /home/oracle/oraInventory to 770.
Changing groupname of /home/oracle/oraInventory to oinstall.
The execution of the script is complete
[root@L-DB-3-6 oraInventory]#
3 、常见错误（检查 dbca 的 log 确认原因） A. 输入 dbca 提示 dbca Exception in thread "main" [oracle@centos ~]$ cd $ORACLE_HOME/cfgtoollogs/dbca
[oracle@centos dbca]$ vi trace.log
java.lang.UnsatisfiedLinkError: /u01/app/oracle/product/10.2.0/db_1/jdk/jre/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
确认是缺少libXp.so，解决方法是找到Linux安装盘，安装libXp包，问题解决
[root@oraclebk ~]# yum install libXp
B. 输入 dbca 提示 dbca Exception in thread "main" [oracle@centos ~]$ cd $ORACLE_HOME/cfgtoollogs/dbca
[oracle@centos dbca]$ vi trace.log
提示IP错误，突然想起要export DISPLAY=172.16.4.41:0.0(连上去的客户机)
[oracle@L-DB-3-6 dbca]$ export DISPLAY=172.16.4.41:0.0
[oracle@L-DB-3-6 dbca]$ dbca
zjport:/home/oracle/product/10.2.0/db_1:Y
八、安装完成后，恢复 Oracle /etc/redhat-release 文件。 Red Hat Enterprise Linux Server release 5.2 (Tikanga)
