oracle的一些操作

--查询sql文的内存使用
SELECT S.MODULE,
       S.*
  FROM v$SQLAREA s
 WHERE s.PARSING_SCHEMA_NAME = 'NEW_CLEAN'
   AND S.MODULE = 'httpd.exe'
   AND sql_text LIKE '%FROM SAISYUBASYO_MST%'

-- 变更默认权ˇ
SELECT * FROM dba_profiles WHERE profile='DEFAULT' AND resource_name='PASSWORD_LIFE_TIME';
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
-- 添加用户
ALTER USER new_clean IDENTIFIED BY new_clean;
用sys登入Oracle DB后,下grant create session to UserName;(UserName是登录出错的用户名)

ALTER USER NEW_CLEAN_CUSTOMIZE IDENTIFIED BY NEW_CLEAN_CUSTOMIZE;
grant create session to NEW_CLEAN_CUSTOMIZE;
grant sysdba to NEW_CLEAN_CUSTOMIZE;

UTL_FILE的使用

      1. create directory dir_new_clean_log as 'd:\new_clean\log';
      2. grant read,write on directory dir_new_clean_log to new_clean;
      3. grant execute on utl_file to new_clean;
