Oracle巡检手册第一部分数据库状态监控首先检查oracle的log，在sqlplus中：show parameter background_dump_dest;select * from v$diag_info;可以得到日志路径1:检查oracle 监听lsnrtcl statusPs –ef|grep ora2:检查oracle初始化参数Select * from v$parameter;3:检查oracle实例状态Select instance_name,version,status,database_status from v$instance;select inst_id,instance_name,host_name,VERSION,TO_CHAR(startup_time,'yyyy-mm-dd hh24:mi:ss')startup_time,status,archiver,database_status FROM gv$instance;4:检查后台进程状态：select name,Description From v$BGPROCESS Where Paddr<>'00'5:查看系统全局区SGA信息select * from v$sga;6: 查看SGA各部分占用内存情况：select * from v$sgastat;select request_misses,request_failures from v$shared_pool_reserved;比较好的状态：REQUEST_MISSES REQUEST_FAILURES为0或者接近0REQUEST_MISSES REQUEST_FAILURES-------------- ----------------007：查看系统SCN号select (select dbms_flashback.get_system_change_number from dual)scn,current_scn,scn_to_timestamp(current_scn)from v$database;8：检查数据库状态：select name,log_mode,open_mode,platform_name from v$database;select inst_id,dbid,name,to_char(created,'yyyy-mm-dd hh24:mi:ss')created,log_mode,to_char(version_time,'yyyy-mm-ddhh24:mi:ss')version_time,open_mode from gv$database;第二部分：数据库空间监控检查表空间使用率select A.tablespace_name, (1 - (A.total) / B.total) * 100 used_percentfrom (select tablespace_name, sum(bytes) totalfrom dba_free_spacegroup by tablespace_name) A,(select tablespace_name, sum(bytes) totalfrom dba_data_filesgroup by tablespace_name) Bwhere A.tablespace_name = B.tablespace_name;检查system表空间内的内容select distinct (owner)from dba_tableswhere tablespace_name = 'SYSTEM'and owner != 'SYS'and owner != 'SYSTEM'unionselect distinct (owner)from dba_indexeswhere tablespace_name = 'SYSTEM'and owner != 'SYS'and owner != 'SYSTEM';输出：no rows selected分析：如果有记录返回，则表明system表空间内存在一些非system和sys用户的对象。

一．Window下关闭Oracle 11g正常在Windows下安全关闭Oracle数据库系统的步骤如下：1.从命令行下找到oracle的BIN目录，然后输入isqlplusctl stop命令停止isqlplus进程。
2.同样在BIN目录下，emctl stop dbconsole停止企业管理器的控制台进程。
3.同样在BIN目录下，lsnrctl stop停止监听进程。
4.在命令行下输入sqlplus /nolog , 然后conn / as sysdba连接到数据库shutdown immediate;====================================================================== select username,password from dba_users; --查看用户信息select username,account_status from dba_users; --查看用户是否解锁alter user scott account unlock; --解锁scott用户alter user scott account lock;--锁scott用户alter user scott identified by tiger; --为scott用户修改密码为tiger创建用户以及给表赋予权限：创建用户create user user_name identified by password;grant dba to user_name；查询表的权限grant select on gecs_law to user_name;select file_name from dba_data_files; --查看数据文件路径select name from v$controlfile; --查看控制文件路径select member from v$logfile; --查看日志文件路径====================================================================== Oracle关于shutdown、startup几个参数：shutdown有四个参数：normal、transactional、immediate、abort。
Oracle 数据库日常巡检指令Oracle数据库的日常巡检内容包括：Oracle数据库基本状况检查；Oracle相关资源的使用情况检查；Oracle数据库性能检查；数据库服务器cpu、mem和I/O 性能检查；数据库服务器安全性及其他事项检查等五大检查项目。
1、数据库基本状况检查（1）、数据库实例状况检查说明：其中“STATUS”表示Oracle当前的实例状态，必须为“OPEN”；“DATABASE_STATUS”表示Oracle当前数据库的状态，必须为“ACTIVE”。
（2）、数据库表空间状态检查说明：输出结果中STATUS应该都为“ONLINE”。
（3）、数据库数据文件检查1 select tablespace_name,status from dba_tablespaces;说明：输出结果中“STATUS”应该都为“AVAILABLE”。
（4）、数据库在线日志检查1 select group#,status,type,member from v$logfile;说明：输出结果应该有3条或3条以上记录，“STATUS”应该为非“INVALID”，非“DELETED”。
“STATUS”的值为空表示正常。
（5）、数据库回滚段检查1 select segment_name,status from dba_rollback_segs;说明：输出结果中所有回滚段的“STATUS”应该为“ONLINE”。
2、数据库相关资源使用情况检查（1）、检查Oracle初始化文件中相关参数值1 select resource_name,max_utilization,initial_allocation, limit_value from v$resource_limit;说明：若字段值【LIMIT_VALU】-【MAX_UTILIZATION】<=5，则表明与RESOURCE_NAME相关的Oracle初始化参数需要调整。
