ORACLE 19c 使用内联外部表看报警日志内容

郑全

比如想看PROD4库的报警文件，

1.建立PROD4实例的报警文件目录
  create directory trace_dir as '/u01/app/oracle/diag/rdbms/prod4/PROD4/trace';

2.使用内联外部表读出报警文件内容最近50条记录，最新的在最前面
  SYS@PROD4> WITH alert_tab AS (
  2    SELECT rownum rn,message
  3    FROM   EXTERNAL (
  4             (
  5              message varchar2(500)
  6             )
  7           TYPE ORACLE_LOADER
  8           DEFAULT DIRECTORY trace_dir
  9           ACCESS PARAMETERS
10           (
11                  FIELDS TERMINATED BY ','
12                  MISSING FIELD VALUES ARE NULL
13                  (message
14                   )
15           )
16           LOCATION ('alert_PROD4.log')
17           REJECT LIMIT UNLIMITED
18        )
19    order by rn desc
20  )
21  select message from alert_tab where rn <50;
