统计信息收集的途径

关于CBO和系统收集信息的操作

使用analyze 收集统计信息
Analyze Statement
The ANALYZE statement can be used to gather statistics for a specific table, index or cluster. The statistics can be computed exactly, or estimated based on a specific number of rows, or a percentage of rows:

ANALYZE TABLE employees COMPUTE STATISTICS;
ANALYZE INDEX employees_pk COMPUTE STATISTICS;

ANALYZE TABLE employees ESTIMATE STATISTICS SAMPLE 100 ROWS;
ANALYZE TABLE employees ESTIMATE STATISTICS SAMPLE 15 PERCENT;DBMS_UTILITY

使用DBMS_UTILITY收集对象或者数据库的统计信息

EXEC DBMS_UTILITY.analyze_schema(‘SCOTT’,’COMPUTE’);
EXEC DBMS_UTILITY.analyze_schema(‘SCOTT’,’ESTIMATE’, estimate_rows => 100);
EXEC DBMS_UTILITY.analyze_schema(‘SCOTT’,’ESTIMATE’, estimate_percent => 15);

EXEC DBMS_UTILITY.analyze_database(‘COMPUTE’);
EXEC DBMS_UTILITY.analyze_database(‘ESTIMATE’, estimate_rows => 100);
EXEC DBMS_UTILITY.analyze_database(‘ESTIMATE’, estimate_percent => 15);DBMS_STATS

使用DBMS_STATS收集对象或者数据库的统计信息
The DBMS_STATS package was introduced in Oracle 8i and is Oracles preferred method of gathering object statistics. Oracle list a number of benefits to using it including parallel execution,
long term storage of statistics and transfer of statistics between servers. Once again, it follows a similar format to the other methods:

EXEC DBMS_STATS.gather_database_stats;
EXEC DBMS_STATS.gather_database_stats(estimate_percent => 15);

EXEC DBMS_STATS.gather_schema_stats(‘SCOTT’);
EXEC DBMS_STATS.gather_schema_stats(‘SCOTT’, estimate_percent => 15);

EXEC DBMS_STATS.gather_table_stats(‘SCOTT’, ‘EMPLOYEES’);
EXEC DBMS_STATS.gather_table_stats(‘SCOTT’, ‘EMPLOYEES’, estimate_percent => 15);

EXEC DBMS_STATS.gather_index_stats(‘SCOTT’, ‘EMPLOYEES_PK’);
EXEC DBMS_STATS.gather_index_stats(‘SCOTT’, ‘EMPLOYEES_PK’, estimate_percent => 15);This package also gives you the ability to delete statistics:

EXEC DBMS_STATS.delete_database_stats;
EXEC DBMS_STATS.delete_schema_stats(‘SCOTT’);
EXEC DBMS_STATS.delete_table_stats(‘SCOTT’, ‘EMPLOYEES’);
EXEC DBMS_STATS.delete_index_stats(‘SCOTT’, ‘EMPLOYEES_PK’);Scheduling Stats

快速刷新物化视图

确认当前操作的实例名

select instance_name,status from v$instance;
select instance_name,status from gv$instance;

确定当前用户的索引类型以及分布情况
select index_name,index_type,status,table_name from user_indexes;

select sid,event,p1,p2 from v$session_wait;

oracle 创建可快速刷新的物化视图

1.创建测试基表
drop table lgc_mv;
create table lgc_mv (id number,
name varchar2(30),
loc varchar2(30),
dep_id number,
sal number);

insert into lgc_mv values(1,’luda’,’hz’,101,5555);
insert into lgc_mv values(2,’luya’,’hz’,102,6666);
insert into lgc_mv values(3,’shaoshan’,’bj’,103,7777);
insert into lgc_mv values(4,’xiaxian’,’xm’,104,5355);
insert into lgc_mv values(5,’langyu’,’hz’,105,5556);
insert into lgc_mv values(6,’sushan’,’wrmj’,106,5457);
insert into lgc_mv values(7,’hens’,’bj’,107,5337);

insert into lgc_mv values(8,’join’,’bj’,107,10240);

drop table sales
create table sales (id number,
name varchar2(30),
dep_id number,
salary number);

insert into sales values(1,’luda’,101,5555);
insert into sales values(2,’luya’,102,6666);
insert into sales values(3,’shaoshan’,103,7777);
insert into sales values(4,’xiaxian’,104,5355);
insert into sales values(5,’langyu’,105,5556);
insert into sales values(6,’sushan’,106,5457);
insert into sales values(7,’hens’,107,5337);
insert into sales values(8,’hludss’,107,6889);
insert into sales values(9,’yasil’,105,7993);

oracle
alter table lgc_mv rename cloumn hob_id to sal;

explain plan set statement_id=’sales’ for select * from sales;
select * from table(dbms_xplan.display);
explain plan set statement_id=’lgc_mv’ for select * from lgc_mv;

2。创建物化视图

alter system set query_rewrite_enabled=true scope=spfile;
alter table lgc_mv noparallel;

查找当前用户拥有的物化视图和状态
SELECT mview_name, refresh_mode, refresh_method,
last_refresh_type, last_refresh_date
FROM user_mviews

drop materialized view lgc_info_mv;

————-测试时候就这样的：
create materialized view lgc_info_mv
parallel
build immediate
refresh complete
enable query rewrite as
select a.dep_id,sum(sal) sum_salary
from lgc_mv a,sales b where a.id=b.id
group by a.dep_id;
————————————-
create materialized view lgc_info_mv
parallel
build immediate
refresh complete
enable query rewrite as
select a.dep_id,sum(sal) sum_salary,count(sal),count(*)
from lgc_mv a,sales b where a.id=b.id
group by a.dep_id;

创建dbms_mview.explain_mview包所需求的表
@?/rdbms/admin/utlxmv.sql
分析物化视图
exec dbms_mview.explain_mview(‘lgc.lgc_info_mv’);
查找分析物化视图分析结果
SELECT capability_name, possible, SUBSTR(related_text,1,8)
AS rel_text, SUBSTR(msgtxt,1,60) AS msgtxt
FROM MV_CAPABILITIES_TABLE
ORDER BY seq;
清除数据
TRUNCATE TABLE mv_capabilities_table
分析后创建基物化视图在对应的表上。
DROP materialized view log on sales;
DROP materialized view log on lgc_mv;

CREATE MATERIALIZED VIEW LOG ON SALES WITH ROWID,SEQUENCE
(id,name,dep_id,salary) INCLUDING NEW VALUES;

CREATE MATERIALIZED VIEW LOG ON LGC_MV WITH ROWID,SEQUENCE
(id,name,loc,dep_id,sal) INCLUDING NEW VALUES;

这时候就要根据里面的东西调试了~一个快速刷新的视图需要根据explain的调试才能知道~~~

4月21号小记

7月份就要考OCM了
最近一直有点忙，但是还是比较容易分心
老婆马上来杭州了，看着口袋那么拮据，往后的日子怎么办·这OCM真要人命，一下去了几万块。

虽然报名时候就考虑到了今年会过得很拮据，但是真的拮据来了还是有点不适应~~~

加把努力！！！

Rac 常用管理命令 一

关于oracle rac的操作命令 — 开发人员熟悉版本

rac的备份不只是数据的备份，也要对ocr以及voting进行备份，所以rac的备份概念和传统的数据库概念并不一样

这篇文档主要讲解oracle RAC的操作文档和实际的备份以及恢复概念，

1.环境
公司的oracle RAC
铁甲人linux 5.5版本
oracle 10201 database
oracle cluster 10201

节点：

node1 ip 231
node2 ip 232

主机：
windows xp sp3 241

2.确定oracle rac服务状态的命令

主要分为4种
crsctl gsdctl onsctl srvctl

（1）crsctl —- 谨慎操作，一般情况不允许做这个操作，除非crs出问题需要重启
这个命令主要用来启动和关闭集群服务

示例：

[root@node1 ~]# crsctl stop crs
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
[root@node1 ~]# crsctl start crs
Attempting to start CRS stack

测试crs，确定集群服务运行健康状态：
ORACLE@node1:/oracle/product/10.2.0/db_1/dbs>crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

（2）crs_ 系列
这系列的命令可以在CRS_HOME中找到，在公司的环境中我没有设置CRS_HOME变量，具体路径为：
/oracle/product/10.2.0/crs/bin

实例：
一：crs_stat -t的命令主要确定oracle rac的全部服务状态

ORACLE@node1:/home/oracle>crs_stat -t
Name Type Target State Host
————————————————————
ora.ldrac.db application ONLINE ONLINE node1
ora….c1.inst application ONLINE ONLINE node1
ora….c2.inst application ONLINE ONLINE node2
ora….SM1.asm application ONLINE ONLINE node1
ora….E1.lsnr application ONLINE ONLINE node1
ora.node1.gsd application ONLINE ONLINE node1
ora.node1.ons application ONLINE ONLINE node1
ora.node1.vip application ONLINE ONLINE node1
ora….SM2.asm application ONLINE ONLINE node2
ora….E2.lsnr application ONLINE ONLINE node2
ora.node2.gsd application ONLINE ONLINE node2
ora.node2.ons application ONLINE ONLINE node2
ora.node2.vip application ONLINE ONLINE node2

ORACLE@node1:/home/oracle>crs_stat -help
Usage: crs_stat [resource_name […]] [-v] [-l] [-q] [-c cluster_member]
crs_stat [resource_name […]] -t [-v] [-q] [-c cluster_member]
crs_stat -p [resource_name […]] [-q]
crs_stat [-a] application -g
crs_stat [-a] application -r [-c cluster_member]
crs_stat -f [resource_name […]] [-q] [-c cluster_member]
crs_stat -ls [resource_name […]] [-q]

示例
ORACLE@node1:/home/oracle>crs_stat -ls
Name Owner Primary PrivGrp Permission
—————————————————————–
ora.ldrac.db oracle oinstall rwxrwxr–
ora….c1.inst oracle oinstall rwxrwxr–
ora….c2.inst oracle oinstall rwxrwxr–
ora….SM1.asm oracle oinstall rwxrwxr–
ora….E1.lsnr oracle oinstall rwxrwxr–
ora.node1.gsd oracle oinstall rwxr-xr–
ora.node1.ons oracle oinstall rwxr-xr–
ora.node1.vip root oinstall rwxr-xr–
ora….SM2.asm oracle oinstall rwxrwxr–
ora….E2.lsnr oracle oinstall rwxrwxr–
ora.node2.gsd oracle oinstall rwxr-xr–
ora.node2.ons oracle oinstall rwxr-xr–
ora.node2.vip root oinstall rwxr-xr–

二： crs_start 这个命令和crsctl start crs 是一样的功能
crs_start 是用来启动集群所有服务的
，命令格式 ：

crs_start -all 启动全部服务
crsctl start/stop resources 启动和关闭资源服务

三 gsdctl gsd控制器 The Global Services Daemon = GSD

关闭 gsdctl stop

PS : 关闭服务可以参考一下命令
[oracle@node1 ~]$ crs_stop ora.ORCL.ORATEST.cs
Attempting to stop `ora.ORCL.ORATEST.cs` on member `node2`
Stop of `ora.ORCL.ORATEST.cs` on member `node2` succeeded.
[oracle@node1 ~]$ crs_stop ora.node1.ASM1.asm
Attempting to stop `ora.node1.ASM1.asm` on member `node1`
Stop of `ora.node1.ASM1.asm` on member `node1` succeeded.
[oracle@node1 ~]$ crs_stop ora.node1.LISTENER_node1.lsnr
Attempting to stop `ora.node1.LISTENER_node1.lsnr` on member `node1`
Stop of `ora.node1.LISTENER_node1.lsnr` on member `node1` succeeded.
[oracle@node1 ~]$ crs_stop ora.node1.ons
Attempting to stop `ora.node1.ons` on member `node1`
Stop of `ora.node1.ons` on member `node1` succeeded.
[oracle@node1 ~]$ crs_stop ora.node1.vip
Attempting to stop `ora.node1.vip` on member `node1`
Stop of `ora.node1.vip` on member `node1` succeeded.
[oracle@node1 ~]$ crs_stop ora.node2.gsd
Attempting to stop `ora.node2.gsd` on member `node2`
Stop of `ora.node2.gsd` on member `node2` succeeded.
[oracle@node1 ~]$ crs_stop ora.node2.ons
Attempting to stop `ora.node2.ons` on member `node2`
Stop of `ora.node2.ons` on member `node2` succeeded.
[oracle@node1 ~]$ crs_stop ora.node1.gsd
Attempting to stop `ora.node1.gsd` on member `node1`
Stop of `ora.node1.gsd` on member `node1` succeeded.

相反启动服务可以用 crs_start 如上只需要把stop改成start就可以了。

四： ASM的使用

在orcale用户下输入

asmcmd
就可以进入asm的介质管理平台

输入help就可以列出一系列操作解释

下一篇： srvctl 的使用 —- 这个是rac常用的管理工具
