GC访问遇到503错误
访问http://ocm2:4889/em后遇到503错误
Oracle 10g grid control 登录时报如下错误,从错误解释可以看出这是数据库连接问题。
Service Unavailable
Servlet error: Service is not initialized correctly. Verify that the repository connection information provided is correct.
一般安装Grid Control的计算机重启后数据库没有自动启动原因会导致以上错误。处理办法很简单那，即启动监听和repository数据库。
