oracle巡检脚本

oracle 日常维护工作内容(1). 每天对ORACLE数据库的运行状态,日志文件,备份情况,数据库的空间使用情况,系统资源的使用情况进行检查,发现并解决问题。

(2). 每周对数据库对象的空间扩展情况,数据的增长情况进行监控,对数据库做健康检查,对数据库对象的状态做检查。

====================每天工作====================1.(1).确认所有的INSTANCE状态正常.登陆到所有数据库或例程,检测ORACLE后台进程:$ps –-ef|grep ora(2). 检查文件系统的使用（剩余空间）。

如果文件系统的剩余空间小于20%，需删除不用的文件以释放空间。

对于业务交易生产系统和数据库日志归档目录,当空间不足,请急时清理.$df -h(3). 检查日志文件和trace文件记录alert和trace文件中的错误.连接到数据库服务器cd 到bdump目录,通常是$ORACLE_BASE/admin/<SID>/bdump‘tail’命令来查看alert_<SID>.log文件如果发现任何新的ORA- 错误,记录并解决(4). 检查数据文件的状态记录状态不是“online”的数据文件，并做恢复。

Select file_name from dba_data_files where status=’OFFLINE’(5). 检查表空间的使用情况SELECT SUM(bytes) / (1024 * 1024) AS free_space, tablespace_nameFROM dba_free_spaceGROUP BY tablespace_name;SELECT a.tablespace_name,a.bytes total,b.bytes used,c.bytes free,(b.bytes * 100) / a.bytes "% USED ",(c.bytes * 100) / a.bytes "% FREE "FROM sys.sm$ts_avail a, sys.sm$ts_used b, sys.sm$ts_free cWHERE a.tablespace_name = b.tablespace_nameAND a.tablespace_name = c.tablespace_name;(6). 检查剩余表空间SELECT tablespace_name, SUM (blocks) AS free_blk,TRUNC (SUM (BYTES) / (1024 * 1024)) AS free_m,MAX (BYTES) / (1024) AS big_chunk_k, COUNT (*) AS num_chunks FROM dba_free_spaceGROUP BY tablespace_name;(7). 检查数据库性能，记录数据库的cpu使用、IO、buffer命中率等等使用vmstat,iostat,glance,top等命令====================每周工作====================(1). 监控数据库对象的空间扩展情况根据本周每天的检查情况找到空间扩展很快的数据库对象,并采取相应的措施alter tablespace 表空间名add datafile '/u1/oradata/userdata_002.ora' size *m;(2). 检查无效的数据库对象SELECT owner, object_name, object_typeFROM dba_objectsWHERE status = 'invalid';(3). 检查不起作用的约束SELECT owner, constraint_name, table_name, constraint_type, statusFROM dba_constraintsWHERE status = 'DISABLED' AND constraint_type = 'P' ;(4). 检查无效的triggerSELECT owner, trigger_name, table_name, statusFROM dba_triggersWHERE status = 'DISABLED';====================每月的工作====================(1). 检查表空间碎片根据本月每周的检查分析数据库碎片情况,找到相应的解决方法(2). 寻找数据库性能调整的机会比较每天对数据库性能的监控报告,确定是否有必要对数据库性能进行调整(3). 数据库性能调整如有必要,进行性能调整(4). 提出下一步空间管理计划根据每周的监控,提出空间管理的改进方法============================================================================|| ★★★Oracle DBA 日常管理★★★||============================================================================目的：这篇文档有很详细的资料记录着对一个甚至更多的ORACLE 数据库每天的，每月的，每年的运行的状态的结果及检查的结果，在文档的附录中你将会看到所有检查，修改的SQL和PL/SQL 代码。

Oracle巡检内容1. Oracle进程检查Ps –ef |grep ora2. CRS进程检查$ps –df |grep d.bin应有：crsd.bin ocssd.bin evmd.bincrsctl check crscrs_stat –tcrs_stat –lsasm进程检查：ps –ef|grep asmORACLE_SID=+ASM1select group_number,name,state,total_mb,free_mb from v$asm_diskgroup;select * from v$asm_disk;检查数据库状态：srvctl status database –d dbname3. Oracle数据库实例状态检查SELECT inst_id, instance_name, host_name, VERSION, TO_CHAR(startup_time, 'yyyy-mm-dd hh24:mi:ss') startup_time, status, archiver,database_status FROM gv$instance;4. Oracle数据库打开状态检查SELECT inst_id, dbid, NAME, TO_CHAR (created, 'yyyy-mm-dd hh24:mi:ss') created, log_mode, TO_CHAR (version_time, 'yyyy-mm-dd hh24:mi:ss') version_time,open_modeFROM gv$database;5. 数据库表空间使用情况检查;5.1 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_freeFROM 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 8;5.2 表空间可用性检查select tablespace_name,status from dba_tablespaces;5.3 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;期望结果：根据现场实际情况，应用用户的缺省表空间不能为system，临时表空间必须为temp。

1 日常巡检1.1 数据库巡检为了保证oracle数据库稳定，高效的运行，每个季度初需要对oracle数据库进行健康检查。

以确定数据库是否存在故障及性能问题。

对于异常状况，上报，进一步诊断、分析，及时解决。

巡检工作包括以下细则：●ALERT文件(alertSID.log)是否出现错误信息●top10等待事件●数据库大小●表空间使用情况●内存配置●三个Top10 SQL●内存命中率●归档方式及备份情况1.1.1 巡检脚本1.1.1.1 AlertSID.log文件位置：1.1.1.2 归档方式及备份情况（1）查看是否为归档方式：（2）说明该数据库备份情况，是否有备份策略。

1.1.1.3 top10等待事件：◆不同的版本，事件的多少不同✧Oracle9iOracle10g1.1.1.4 数据库大小：1.1.1.5 表空间使用情况：1.1.2 Top10segment◆查找系统数据量最大的10个段1.1.2.1 内存配置✧oracle9i：✧Oracle10g:1.1.2.2 三个Top10 SQL1.1.2.3 命中率1.1.2.4 死锁死锁查询：SELECT /*+ rule */ername,decode(l.type, 'TM', 'TABLE LOCK', 'TX', 'ROW LOCK', NULL) LOCK_LEVEL, o.owner,o.object_name,o.object_type,s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuserFROM v$session s, v$lock l, dba_objects oWHERE l.sid = s.sidAND l.id1 = o.object_id(+)AND ername is NOT NULL解锁：杀死该session：alter system kill session 'sid,serial#'。

Oracle数据库日常检查A. 查看所有的实例及其后台进程是否正常确认所有的instance工作正常，登陆到所有的数据库或instance上，检测oracle后台进程$env | grep SIDORACLE_SID=UWNMS3B．检查文件系统的使用情况如果文件系统的剩余空间小于10％，则需要删除不必要的文件以释放空间。
