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)
结果今天早上客户那边反馈应用有报ORA-29548错
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; 37 38 -- Add a row in registry$history to indicate this script was run. 39 40 EXECUTE IMMEDIATE 'insert into registry$history 41 (action_time, action, namespace, version, id, comments) 42 values(SYSTIMESTAMP, ''jvmpsu.sql'', ''SERVER'', 43 ''11.2.0.4.221018OJVMPSU'', 0, ''RAN jvmpsu.sql'')'; 44 45 END IF; 46 47 EXECUTE IMMEDIATE 'alter system set java_jit_enabled = ' || :jitstate; 48 49 END; 50 / BEGIN * 第 1 行出现错误: ORA-01843: 无效的月份 ORA-06512: 在 line 8

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)
