oracle数据库巡检内容1.检查数据库基本状况在本节中主要对数据库的基本状况进行检查，其中包含：检查Oracle实例状态，检查Oracle服务进程，检查Oracle监听进程，共三个部分。1.1.检查Oracle实例状态SQL>selectinstance_name,host_name,startup_time,status,database_statusfromv$instance;INSTANCE_NAMEHOST_NAMESTARTUP_TIMESTATUSDATABASE_STATUS---------------------------------------------------------------------------------CKDBAS142009-5-79:3OPENACTIVE其中“STATUS”表示Oracle当前的实例状态，必须为“OPEN”；“DATABASE_STATUS”表示Oracle当前数据库的状态，必须为“ACTIVE”。SQL>selectname,log_mode,open_modefromv$database;NAMELOG_MODEOPEN_MODE--------------------------------------CKDBARCHIVELOGREADWRITE其中“LOG_MODE”表示Oracle当前的归档方式。“ARCHIVELOG”表示数据库运行在归档模式下，“NOARCHIVELOG”表示数据库运行在非归档模式下。在我们的系统中数据库必须运行在归档方式下。1.2.检查Oracle服务进程$ps-ef|grepora_|grep-vgrep&&ps-ef|grepora_|grep-vgrep|wc–loracle296010May07?00:01:02ora_pmon_CKDBoracle296210May07?00:00:22ora_psp0_CKDBoracle296410May07?00:00:00ora_mman_CKDBoracle296610May07?00:03:20ora_dbw0_CKDBoracle296810May07?00:04:29ora_lgwr_CKDBoracle297010May07?00:10:31ora_ckpt_CKDBoracle297210May07?00:03:45ora_smon_CKDBoracle297410May07?00:00:00ora_reco_CKDBoracle297610May07?00:01:24ora_cjq0_CKDBoracle297810May07?00:06:17ora_mmon_CKDBoracle298010May07?00:07:26ora_mmnl_CKDBoracle298210May07?00:00:00ora_d000_CKDBoracle298410May07?00:00:00ora_s000_CKDBoracle299410May07?00:00:28ora_arc0_CKDBoracle299610May07?00:00:29ora_arc1_CKDBoracle300010May07?00:00:00ora_qmnc_CKDBoracle362510May07?00:01:40ora_q000_CKDBoracle3159410Jul20?00:00:00ora_q003_CKDBoracle238021005:09?00:00:33ora_j000_CKDB19在检查Oracle的进程命令输出后，输出显示至少应包括以下一些进程：.Oracle写数据文件的进程，输出显示为：“ora_dbw0_CKDB”.Oracle写日志文件的进程，输出显示为：“ora_lgwr_CKDB”.Oracle监听实例状态的进程，输出显示为：“ora_smon_CKDB”.Oracle监听客户端连接进程状态的进程，输出显示为：“ora_pmon_CKDB”.Oracle进行归档的进程，输出显示为：“ora_arc0_CKDB”.Oracle进行检查点的进程，输出显示为：“ora_ckpt_CKDB”.Oracle进行恢复的进程，输出显示为：“ora_reco_CKDB”1.3.检查Oracle监听状态/home/oracle>lsnrctlstatusLSNRCTLforLinux:Version10.2.0.2.0-Productionon23-JUL-200914:11:53Copyright(c)1991,2005,Oracle.Allrightsreserved.Connectingto(ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))STATUSoftheLISTENER------------------------AliasLISTENERVersionTNSLSNRforLinux:Version10.2.0.2.0-ProductionStartDate07-MAY-200909:35:52Uptime77days4hr.36min.0secTraceLeveloffSecurityON:LocalOSAuthenticationSNMPOFFListenerParameterFile/data/oracle/product/10.2.0/network/admin/listener.oraListenerLogFile/data/oracle/product/10.2.0/network/log/listener.logListeningEndpointsSummary...(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=AS14)(PORT=1521)))ServicesSummary...Service"CKDB"has1instance(s).Instance"CKDB",statusREADY,has1handler(s)forthisservice...Service"CKDBXDB"has1instance(s).Instance"CKDB",statusREADY,has1handler(s)forthisservice...Service"CKDB_XPT"has1instance(s).Instance"CKDB",statusREADY,has1handler(s)forthisservice...Thecommandcompletedsuccessfully“ServicesSummary”项表示Oracle的监听进程正在监听哪些数据库实例，输出显示中至少应该有“CKDB”这一项。检查监听进程是否存在：[oracle@AS14~]$ps-ef|greplsn|grep-vgreporacle295410May07?00:01:17/data/oracle/product/10.2.0/bin/tnsl...
