问题描述：
客户一套单机10.2.0.5 on Linux , 我给了打了最后的PSU： 20299014(10.2.0.5.19)。 然后再dbca建库， 按以前11g的经验，是不需要再运行“ @catbundle.sql psu apply”
后面客户反应exp导数有报错：

原因分析：
在MOS找了一下，只有一个类似的，但版本对不上。不过它给了我思路，这个问题可能是打PSU引进来的。
查看数据库的PSU情况, dba_registry_history记录竟然是空！这跟11g不一样。看来10g打完PSU后，dbca建库还是要其他步骤要做。

Bugs fixed:
alter session set nls_timestamp_format = "yyyy-mm-dd hh24:mi:ss.ff";

解决方案：
按mos的说明，我们来执行“ @catbundle.sql psu apply”

alter system set java_jit_enabled =FALSE
