.用srvctl命令配置service
除了用DBCA图形方式，还能够使用命令方式配置service，这样的方法对于维护远程尤事实上用。不管是创建还是维护都是用一个命令srvctl，先看一下srvctl命令和service相关的语法。例如以下：
创建service
[[email protected] ~]$ srvctl add service -h
Usage: srvctl add service -d <name> -s<service_name> -r "<preferred_list>" [-a"<available_list>"] [-P <TAF_policy>]
-d<name> Unique name forthe database
-s<service> Service name
-r"<pref_list>" List ofpreferred instances
-a"<avail_list>" List ofavailable instances
-P<TAF_policy> TAF policy (NONE,BASIC, or PRECONNECT)
Usage: srvctl add service -d <name> -s<service_name> -u {-r "<new_pref_inst>" | -a"<new_avail_inst>"}
-d<name> Unique name forthe database
-s<service> Service name
-u Add a new instance to serviceconfiguration
-r<new_pref_inst> Name of newpreferred instance
-a<new_avail_inst> Name of new available instance
-h Print usage
[[email protected] ~]$
示比例如以下：
Felix1。felix2为实例名。Felix是数据库名；策略是：BASIC
[[email protected]~]$ srvctl add service -d felix -s taf_srvctl -r felix2 -a felix1 -P BASIC
[[email protected]~]$
查看service配置
[[email protected] ~]$ srvctl config service -d felix-a
taf_server PREF: felix1 AVAIL: felix2 TAF: basic
taf_srvctl PREF: felix2 AVAIL: felix1 TAF: BASIC
[[email protected] ~]$
[[email protected] ~]$ srvctl config service -d felix-h
Usage: srvctl config service -d <name> [-s<service_name>] [-a] [-S <level>]
-d<name> Unique name forthe database
-s<service> Service name
-a Additional attributes
-S<level> Additionalinformation for EM Console
-h Print usage
[[email protected] ~]$
假设不指定“-s service_name”,就会显示全部的service配置。这些配置仅仅包含preferred和avilable instance。
使用-a选项，还会显示TAF的信息。
是否自己主动执行
数据库启动时，会自己主动启动全部的service。有时为了维护的须要，须要禁用这个特性。在维护完毕之后再启动这个特性。
[[email protected] ~]$ srvctl disable service -h
Usage: srvctl disable service -d <name> -s"<service_name_list>" [-i <inst_name>]
-d<name> Unique name forthe database
-s"<serv,...>" Commaseparated service names
-i<inst> Instance name
-h Print usage
[[email protected] ~]$
[[email protected] ~]$ srvctl disable service -d felix-s taf_server -i felix1
[[email protected] ~]$ srvctl config service -d felix-a
taf_server PREF: felix1 AVAIL: felix2 TAF: basic
Service taf_server is disabled on instance(s) felix1.
taf_srvctl PREF: felix2 AVAIL: felix1 TAF: BASIC
[[email protected] ~]$
[[email protected] ~]$ srvctl disable service -d felix-s taf_server
PRKP-1024 : The service taf_server is stillrunning.
关闭服务service并diable：
[[email protected] ~]$ srvctl stop service -h
Usage: srvctl stop service -d <name> [-s"<service_name_list>" [-i <inst_name>]] [-f]
-d<name> Unique name forthe database
-s"<serv,...>" Commaseparated service names
-i<inst> Instance name
-f Disconnect all sessionsduring stop or relocate service operations
-h Print usage
[[email protected] ~]$ srvctl stop service -d felix -staf_server
[[email protected] ~]$ srvctl config service -d felix-a
taf_server PREF: felix1 AVAIL: felix2 TAF: basic
taf_srvctl PREF: felix2 AVAIL: felix1 TAF: BASIC
[[email protected] ~]$ srvctl disable service -d felix-s taf_server
[[email protected] ~]$ srvctl config service -d felix-a
taf_server PREF: felix1 AVAIL: felix2 TAF: basic
Service taf_server is disabled.
taf_srvctl PREF: felix2 AVAIL: felix1 TAF: BASIC
[[email protected] ~]$
启动service
[[email protected] ~]$ srvctl start service -h
Usage: srvctl start service -d <name> [-s"<service_name_list>" [-i <inst_name>]] [-o<start_options>]
-d<name> Unique name forthe database
-s"<serv,...>" Commaseparated service names
-i<inst> Instance name
-o<start_options> Options to startupcommand (e.g. open, mount, or nomount)
-h Print usage
[[email protected] ~]$
[[email protected] ~]$ srvctl start service -d felix -s taf_server
[[email protected] ~]$
查看service状态。
[[email protected] ~]$ srvctl status service -h
Usage: srvctl status service -d <name> [-s"<service_name_list>"] [-f] [-v] [-S <level>]
-d<name> Unique name forthe database
-s"<serv,...>" Commaseparated service names
-f Include disabled applications
-v Verbose output
-S<level> Additionalinformation for EM Console
-h Print usage
[[email protected] ~]$
[[email protected] ~]$ srvctl status service -d felix -s taf_server -f -v
Service taf_server is running on instance(s)felix2
[[email protected] ~]$ srvctl status service -d felix -s taf_server -f -v -S 3
#@=info: operation={status} config={full}ver={10.2.0.0.0}
