Oracle 建立触发器把某个存储过程镶到内存中 提高运算效率

创建该存储过程

SQL>@...\dbmspool.sql

查看该包是否创建

SQL>desc dbms_shared_pool

创建触发器

SQL>conn hr/hr;

SQL>CREATE OR REPLACE TRIGGER "HR".HR_START_TR AFTER

STARTUP ON DATABASE

begin

sys.DBMS_SHARED_POOL.KEEP('HR.ADD_JOB_HISTORY');

end;

授权给HR

grant execute on dbms_shared_pool to HR;

在关闭数据库之前验证内存中是否有add_job_history

select owner,name,type from v$db_object_cache

where owner='HR' and type='PROCEDURE';

重启数据库 再次查看下内存中是否有该存储过程

select owner,name,type from v$db_object_cache

where owner='HR' and type='PROCEDURE';
