Linux操作系统上安装oracle 10g，在启动dbca的时候报 Exception in thread "main" 错误，详细内容如下：

[oracle@centos ~]$ dbca
Exception in thread "main"
[oracle@rac1 ~]$

经检查dbca的log如下：

[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

注意标记为红色的行，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。

安装过程如下：

[root@centos Server]# rpm -Uvh libXp-1.0.0-8.1.el5.i386.rpm
warning: libXp-1.0.0-8.1.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing... ########################################### [100%]
1:libXp ########################################### [100%]

安装完成后，检查libXp包状态

[root@centos Server]# rpm -qa|grep Xp
libXpm-3.5.5-3
libXp-1.0.0-8.1.el5
