数据库打patch建议设置nls_language为英文

发表于 2023 年 12 月 3 日 由 惜分飞

昨晚给客户11.2.0.4打比较新的psu和ojvm patch(主要为了修复安全扫描漏洞)
20231203185616

结果今天早上客户那边反馈应用有报ORA-29548错
ORA-29548
该错误比较明显应该是和java有关系,在本次变更中最大可能就是ojvm有关系,查看ojvm的postinstall.sql执行日志,发现如下问题

 34  -- Check the validity of JAVAVM and let the registry be updated accordingly.
 35  
 36      initjvmaux.validate_javavm;

确认JServer JAVA Virtual Machine组件无效,很可能是ojvm的postinstall.sql执行失败有关系,而引起这个失败的原因是由于“ORA-01843: 无效的月份”,根据经验,引起这个问题的可能是由于win汉语环境中日期/时间的显示格式导致

SQL> select sysdate from dual;

SYSDATE
--------------
03-12月-23

设置为英文格式显示

SQL> alter session set nls_language='American';

Session altered.

SQL> select sysdate from dual;

SYSDATE
------------
03-DEC-23

重新执行postdeinstall和postinstall脚本之后,组件状态恢复正常,软件功能也恢复正常

自此提醒由于oracle 环境语言默认显示的问题导致某些patch不能正常打成功,建议在执行数据库patch或者升级之时,把数据库语言环境调整为英文nls_language=’American’,以避免本次出现的不必要的麻烦(以前由于大部分客户没有是使用jvm这个功能组件因此没有暴露该问题)
