在一套DB服务器上运行DBCA 命令，报错：
[Oracle@game_db ~]$ dbca
Exception in thread "main"
[oracle@game_db ~]$
[oracle@game_db ~]$ exportDISPLAY=1921.68.3.189:0.0
[oracle@game_db ~]$ dbca
Exception in thread "main"
几年都没有遇到这种问题了，起初以为是DISPLAY变量的问题，设置以后也不行，查看了一个DBCA的log 日志：
[oracle@game_db scripts]$ cd $ORACLE_HOME/cfgtoollogs/dbca
[oracle@game_db dbca]$ ls
trace.log
[oracle@game_db dbca]$ tail -50 trace.log

原因很明显，少包了：
libXp.so.6: cannot open shared object file:No such file or directory
验证一下包：
[oracle@game_db dbca]$ rpm -qa|grep libXp
libXpm-devel-3.5.5-3
libXpm-3.5.5-3
将libXp 包打上：
[root@game_db Server]# ll
-rwxrwSrwx 1 root root 22996 2007-07-26libXp-1.0.0-8.1.el5.i386.rpm
-rwxrwSrwx 1 root root 15262 2007-07-26libXp-devel-1.0.0-8.1.el5.i386.rpm
[root@game_db Server]# rpm -ivh libXp*.rpm
warning: libXp-1.0.0-8.1.el5.i386.rpm:Header V3 DSA signature: NOKEY, key ID 37017186

libXp-1.0.0-8.1.el5

在次DBCA 成功：
[root@game_db ~]# xhost +

[root@game_db ~]# su - oracle
[oracle@game_db ~]$ exportDISPLAY=192.168.3.189:0.0
