查询DBA在系统中的打补丁信息

1. select * from ad_patch_drivers          /*查看已经打了哪些Patch*/

2. select * from ad_patch_runs             /*查看打patch的时间，目录等信息*/

3. select * from ad_patch_driver_langs /*查看patch的语言*/

4. 查询补丁名称、语言、打Patch的开始时间、打Patch的完成时间：

SELECT driver.driver_file_name 补丁名称,

       lang.language 语言,

       TO_CHAR(run.start_date, ‘RRRR-MM-DD HH24:MI:SS‘) 开始时间,

       TO_CHAR(run.end_date, ‘RRRR-MM-DD HH24:MI:SS‘) 完成时间

  FROM ad_patch_runs         run,

           ad_patch_driver_langs lang,

           ad_patch_drivers      driver,

           ad_applied_patches    applied

WHERE run.patch_driver_id = driver.patch_driver_id

    AND driver.applied_patch_id = applied.applied_patch_id

   AND lang.patch_driver_id = driver.patch_driver_id ORDER BY 3,4,1,2

--可以统计打Patch的时间，有利于对产品环境的打Patch预计时间和计划安排。
