10g RAC巡检脚本

 ===========================SRVCTL============================

1.列出配置的所有数据库
srvctl config database

2.显示指定集群数据库的所有服务
srvctl config service -d GDTV

3.查看所有实例和服务的状态
srvctl status database -d GDTV

 

4.查看单个实例的状态
srvctl status service -d GDTV -s <service_name>

5.特定节点上节点应用程序的状态
srvctl status nodeapps -n DBSERVER1
srvctl status nodeapps -n DBSERVER2

6.列出RAC数据库的配置
srvctl config database -d GDTV

7.显示节点应用程序的配置 —（VIP、GSD、ONS、监听器）
srvctl config nodeapps -n DBSERVER1 -a -g -s -l
srvctl config nodeapps -n DBSERVER2 -a -g -s -l

=========================================进程检查==================
8. Oracle进程检查

Ps –ef |grep ora_

9. CRS进程检查

ps -ef | grep oracm 

$ps –df |grep d.bin

       应有：crsd.bin ocssd.bin evmd.bin

crsctl check crs

crs_stat –t

crs_stat –ls

=================alert.log====================================

8.查看各个instance的alert.log

 

=====================instance 配置参数========================

9.查看spfile.ora  查看profile

====================参看监听状态==============================

1.集群中所有正在运行的实例

SELECT
inst_id
, instance_number inst_no
, instance_name inst_name
, parallel
, status
, database_status db_status
, active_state state
, host_name host
FROM gv$instance
ORDER BY inst_id;

INST_ID INST_NO INST_NAME PAR STATUS DB_STATUS STATE HOST
-------- -------- ---------- --- ------- ------------ --------- -------
1 1 orcl1 YES OPEN ACTIVE NORMAL rac1
2 2 orcl2 YES OPEN ACTIVE NORMAL rac2

SELECT inst_id, instance_name, host_name, VERSION, TO_CHAR (startup_time, 'yyyy-mm-dd hh24:mi:ss') startup_time, status, archiver, database_status FROM gv$instance;

 

2.检查参数
show paramter

3.检查SGA和PGA

show sga
select name ,value/1024/1024/1024 from gv$sysstat where name like '%pga%';
select name ,value/1024/1024/1024 from v$sysstat where name like '%pga%';

 

4.检查查询服务器的运行模式和数据库安装选项
   set linesize 200
   select * from v$option;

5.用户检查
col temporary_tablespace for a21
select username,account_status,default_tablespace,temporary_tablespace,created from dba_users;

select a.username , a.temporary_tablespace "Temporary Tablespace" , b.contents
from dba_users a , dba_tablespaces b
where a.temporary_tablespace=b.tablespace_name
and b.contents <> 'TEMPORARY';

6、控制文件检查

col name for a60
select * from v$controlfile;

7、无效对象检查
   col OBJECT_NAME for a24
SELECT owner , object_name, object_type,status ,LAST_DDL_TIME  FROM dba_objects WHERE status like 'INVALID';

8、表空间和数据文件检查

1）数据文件
col file_name for a56
set linesize 300
select file_id,file_name,tablespace_name,autoextensible from dba_data_files;

select count(*) from v$datafile;

show parameter db_files

select name from v$datafile
union
select member from v$logfile
union
select name from v$controlfile
union
select name from v$tempfile；

SELECT file#, ts#, NAME, status, BYTES / 1024 / 1024 size_mb FROM v$datafile UNION ALL SELECT file#, ts#, NAME, status, BYTES / 1024 / 1024 size_mb FROM v$tempfile;

2）表空间
set linesize 300
col tablespace_name for a16
SELECT upper(f.tablespace_name) "tablespace_name",
       d.Tot_grootte_Mb "tablespace(M)",
       d.Tot_grootte_Mb - f.total_bytes "used(M)",
       round((d.Tot_grootte_Mb - f.total_bytes) / d.Tot_grootte_Mb * 100,2) "use%",
       f.total_bytes "free_space(M)",
       round(f.total_bytes / d.Tot_grootte_Mb * 100,2) "free%",
       f.max_bytes "max_block(M)"
FROM      
    (SELECT tablespace_name,
            round(SUM(bytes)/(1024*1024),2) total_bytes,
            round(MAX(bytes)/(1024*1024),2) max_bytes
      FROM sys.dba_free_space
      GROUP BY tablespace_name) f,
      (SELECT dd.tablespace_name, round(SUM(dd.bytes)/(1024*1024),2) Tot_grootte_Mb
       FROM   sys.dba_data_files dd
      GROUP BY dd.tablespace_name) d
WHERE d.tablespace_name = f.tablespace_name    
ORDER BY 4 DESC;
 

表空间的空间使用情况

SELECT   df.tablespace_name, COUNT (*) datafile_count,
ROUND (SUM (df.BYTES) / 1048576) size_mb,
ROUND (SUM (free.BYTES) / 1048576, 2) free_mb,
ROUND (SUM (df.BYTES) / 1048576 - SUM (free.BYTES) / 1048576, 2 ) used_mb,
ROUND (MAX (free.maxbytes) / 1048576, 2) maxfree,
100 - ROUND (100.0 * SUM (free.BYTES) / SUM (df.BYTES), 2) pct_used,
ROUND (100.0 * SUM (free.BYTES) / SUM (df.BYTES), 2) pct_free
FROM dba_data_files df,
(SELECT   tablespace_name, file_id, SUM (BYTES) BYTES, MAX (BYTES) maxbytes FROM dba_free_space GROUP BY tablespace_name, file_id) free
WHERE df.tablespace_name = free.tablespace_name(+) AND df.file_id = free.file_id(+)
GROUP BY df.tablespace_name ORDER BY ；

表空间可用性检查
select tablespace_name,status from dba_tablespaces;

临时表空间使用情况和性能检查

SELECT tablespace_name, extent_management, block_size, initial_extent, next_extent, min_extents, max_extents, pct_increase FROM dba_tablespaces WHERE CONTENTS = 'TEMPORARY';
SELECT username, default_tablespace, temporary_tablespace FROM dba_users;

    select tablespace_name,initial_extent,next_extent,max_extents,pct_increase,extent_management,status from dba_tablespaces order by  extent_management;

     select tablespace_name,EXTENT_MANAGEMENT,SEGMENT_SPACE_MANAGEMENT from dba_tablespaces;
