关于‘Instance “ora10g”, status READY, has 1 handler(s) for this service…’
中status 状态解释：
这个status 指的的是instance 的状态
Instance Specifies the name of the instance associated with the service along
with its status and number of service handlers associated with the
service
Status can be one of the following:
■ A READY status means that the instance can accept connections.
—–实例是动态由pmon注册，所以显示的status 当然是‘ready’
■ A BLOCKED status means that the instance cannot accept connections.
—–实例无法接受连接，一般是实例处于nomount 状态下，pmo本文来源gaodai#ma#com搞*!代#%^码$网*n 无法将注册到监听，因为这时数据库还没有打开pmon无法确定db能否对外服务
■ A READY/SECONDARY status means that this is a secondary instance in an Oracle9 i Real Application Clusters
primary/secondary configuration and is ready to accept connections.
■ An UNKNOWN status means that the instance is registered statically in the listener.ora file rather than dynamically
with service registra tion. Therefore, the status is non known.
——这个‘unknown’ 表征实例是静态注册到监听
