Oracle job 管理
SVRMGR> select * from dba_jobs;
初始化相关参数job_queue_processes
alter system set job_queue_processes=39 scope=spfile;//最大值不能超过1000 ;job_queue_interval = 10 //调度作业刷新频率秒为单位
DBA_JOBS describes all jobs in the database.
USER_JOBS describes all jobs owned by the current user
1 select job,what,to_char(last_date,'yyyy-mm-dd HH24:mi:ss'),to_char(next_date,'yyyy-mm-dd HH24:m),interval from dba_jobs where job in (325,295)
2 select job,what,last_date,next_date,interval from dba_jobs where job in (1,3);
查询job的情况。
show paramter background_dump_dest.
看alter.log 和trace

请问我如何停止一个JOB
SQL> exec dbms_job.broken(1,true)
PL/SQL 过程已成功完成。
SQL>commit //必须提交否则无效
启动作业
SQL> exec dbms_job.broken(1,false)
PL/SQL 过程已成功完成。
停其他用户的job
SQL>exec sys.dbms_ijob.broken(98,true);
SQL>commit;
============================
exec dbms_job.broken(:job) 停止
exec dbms_job.broken(186,true) //标记位broken
exec dbms_job.broken(186,false)//标记为非broken
exec dbms_job.broken(186,false,next_day(sysdate,'monday')) //标记为非broken,指定执行时间
exec dbms_job.remove(:job);删除
exec dbms_job.remove(186);
commit;
把一个broken job重新运行
三、查看相关job信息
1、相关视图
dba_jobs
all_jobs
user_jobs
dba_jobs_running 包含正在

3oracle数据库的字符集更改
A、oracle server 端 字符集查询
select userenv(‘language’) from dual
其中NLS_CHARACTERSET 为server端字符集
NLS_LANGUAGE 为 server端字符显示形式
B、查询oracle client端的字符集
$echo $NLS_LANG
如果发现你select 出来的数据是乱码,请把client端的字� ......
导出Oracle数据库结构
1.方法一:直接写sql语句
//获取一个SCHEMA下的所有建表和建索引的语法,以scott为例:
spool portal_schema.sql
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name)
from USER_TABLES u;
SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name)
from USER_INDEXES u;
spool off;
2. ......
解决办法:
1.使用Oracle用户登录系统,在CMD中启用SQLPLUS
2.sqlplus /nolog
3.SQL> connect /as sysdba
Connected.
4.SQL> alter user system account unlock;
User altered.
锁定账号方法:
