oracle触发器执行失败

oracle数据库 使用触发器监控BK_USER_ACTIVE表的增删改操作并将其记录到trig_sql表中
使用的SQL脚本如下：
1.创建trig_sql表用于记录BK_USER_ACTIVE表的增删改操作

create table trig_sql(
         LT DATE not null primary key,
         SID NUMBER,
     　   SERIAL#       NUMBER,
         USERNAME       VARCHAR2(30),
         OSUSER    VARCHAR2(64),
         MACHINE       VARCHAR2(32),
         TERMINAL       VARCHAR2(16),
         PROGRAM       VARCHAR2(64),
         SQLTEXT       VARCHAR2(2000),
         STATUS    VARCHAR2(30),
         CLIENT_IP       VARCHAR2(60)
);

2.创建trig_sql索引

create index idx_time on trig_sql (LT);

3.创建触发器pri_test BK_USER_ACTIVE为要监控的表

create or replace trigger pri_test
  after insert or update or delete on BK_USER_ACTIVE for each row
DECLARE
   PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
  IF inserting THEN
    INSERT INTO trig_sql
        select sysdate,s.SID, s.SERIAL#, s.USERNAME, s.OSUSER,
               s.MACHINE, s.TERMINAL, s.PROGRAM, q.sql_text line,
               'INSERT',
              sys_context('userenv','ip_address')
          from v$sql q, v$session s
         where s.audsid=(select userenv('SESSIONID') from dual)
           and s.prev_sql_addr=q.address
           AND s.PREV_HASH_VALUE = q.hash_value;
    COMMIT;
  ELSIF deleting  then
      INSERT INTO trig_sql
           select sysdate,s.SID, s.SERIAL#, s.USERNAME, s.OSUSER,
                       s.MACHINE, s.TERMINAL, s.PROGRAM, q.sql_text line,
                       'DELETE',
                       sys_context('userenv','ip_address')
             from v$sql q, v$session s
            where s.audsid=(select userenv('SESSIONID') from dual)
             and s.prev_sql_addr=q.address
             AND s.PREV_HASH_VALUE = q.hash_value;
    COMMIT;
  ELSIF updating then
    INSERT INTO trig_sql
         select sysdate,s.SID, s.SERIAL#, s.USERNAME, s.OSUSER,
                     s.MACHINE, s.TERMINAL, s.PROGRAM, q.sql_text line,
                     'UPDATE',
                     sys_context('userenv','ip_address')
           from v$sql q, v$session s
          where s.audsid=(select userenv('SESSIONID') from dual)
           and s.prev_sql_addr=q.address
           AND s.PREV_HASH_VALUE = q.hash_value;
    COMMIT;
   END IF;
END;

SQL执行后对BK_USER_ACTIVE执行增删改操作触发器执行错误信息提示如下图

ORA-04098: trigger 'JIZHANG.PRI_TEST' is invalid and failed re-validation
, Time: 0.071000s

用如下SQL脚本查看触发器执行失败详细信息

select * from SYS.USER_ERRORS where NAME = upper('pri_test');

触发器执行失败详细信息

PRI_TEST TRIGGER 1 10 25 PL/SQL: ORA-00942: table or view does not exist ERROR 0
PRI_TEST TRIGGER 2 5 5 PL/SQL: SQL Statement ignored ERROR 0

网上调查后，个人认定失败是oracle数据库用户权限问题导致（oracle用户继承自角色的权限不包含存储过程，函数，触发器等特殊对象）
网上方案：需要重新对用户显示赋权（trigger相关）
但在网上并没有找到能解决我问题的具体方案。遂发布问答咨询网友，请不吝赐教！
