#此处说明该主机地址为ocm1.oracle.domain，开启的监听端口有1521,1522,1600

Services Summary... Service "POD" has 1 instance(s).   Instance "POD", status READY, has 1 handler(s) for this service...

#此处说明有一个服务名POD的服务，数据库实例名为POD，状态READY说明其目前处于动态注册

Service "POD1" has 1 instance(s).   Instance "POD", status UNKNOWN, has 1 handler(s) for this service...

#此处说明有一个服务名为POD1的服务，数据库的实例名为POD，状态UNKNOWN说明其目前是静态注册

Service "PODS" has 1 instance(s).   Instance "POD", status READY, has 2 handler(s) for this service...

#此处说明有一个服务名为PODS的服务，数据库实例名为POD，状态READY说明其是动态注册

 

Service "repos" has 2 instance(s).   Instance "repos", status UNKNOWN, has 1 handler(s) for this service...   Instance "repos", status READY, has 1 handler(s) for this service... The command completed successfully

#此处说明有一个服务名为repos的服务，对应数据库实例为repos，UNKNOWN,READY状态说明其目前有一个静态注册和一个动态注册

service详解

Service "POD" has 1 instance(s).   Instance "POD", status READY, has 1 handler(s) for this service...     Handler(s):       "DEDICATED" established:0 refused:0 state:ready          LOCAL SERVER

#名为POD的服务，对应数据库实例为POD，状态READY说明其处于动态注册

DEDICATED" established:0 refused:0 state:ready说明是专有连接，连接数为0拒绝数为0，状态：动态

Service "POD1" has 1 instance(s).   Instance "POD", status UNKNOWN, has 1 handler(s) for this service...     Handler(s):       "DEDICATED" established:2 refused:0          LOCAL SERVER

#名为POD1的服务，对应数据库实例为POD，状态UNKNOWN说明其处于静态注册

DEDICATED" established:2 refused:0说明是专有连接，连接数为2拒绝数为0

Service "PODS" has 1 instance(s).   Instance "POD", status READY, has 2 handler(s) for this service...     Handler(s):       "D001" established:0 refused:0 current:0 max:1022 state:ready          DISPATCHER          (ADDRESS=(PROTOCOL=tcp)(HOST=ocm1.oracle.domain)(PORT=37290))       "D000" established:0 refused:0 current:0 max:1022 state:ready          DISPATCHER          (ADDRESS=(PROTOCOL=tcp)(HOST=ocm1.oracle.domain)(PORT=37288))

#名为PODS的服务，对应数据库实例名为POD的数据库，READY状态说明其为动态注册

"D001" established:0 refused:0 current:0 max:1022 state:ready

 "D000" established:0 refused:0 current:0 max:1022 state:ready

这里说明其为share模式，目前，两个dispatcher目前都连接为0，拒绝为0，最大数为1022，状态是动态注册

对应sql查询

------------------------------------------------------------------------------------------------------------------------------------------------------------------

Service "repos" has 2 instance(s).   Instance "repos", status UNKNOWN, has 1 handler(s) for this service...     Handler(s):       "DEDICATED" established:0 refused:0          LOCAL SERVER   Instance "repos", status READY, has 1 handler(s) for this service...     Handler(s):       "DEDICATED" established:0 refused:0 state:ready          LOCAL SERVER

#repos服务对应的实例有2个，但此处都为实例repos，一个为静态UNKNOWN,一个为动态READY，目前连接数都为0，拒绝也为0 The command completed successfull
