I'm a fireman. (DBA Assistance)

Just to work, the coachman back home, suddenly a customer phone said business use not up, doubt is Oracle database problem, must immediately solve, helpless, I only quiet heart to deal with the fault. As a DBA, the first thing to do is to be calm and second to be careful.

I through the remote, connected to the client server, the first step: I query the database is open, the query found that the database is running normally, the second step to query the monitoring service is normal, found that there is a problem monitoring, has been shown a standstill state. I look at the listening log, the database log, no obvious display. Waited about five minutes to show: 650) this.width=650; "title=" Qq20151204164913.png "src=" http://s1.51cto.com/wyfs02/M00/77/0B/ Wkiol1zhydcdpxv0aajf9bfqfb0883.png "alt=" Wkiol1zhydcdpxv0aajf9bfqfb0883.png "/>

See this, I will look at the monitoring file, no changes, looked at the listening log, did not find any problem, I think it is not listening log file too large. Later I delete the log file, restart monitoring, found that the problem is resolved. Customers can get off work in time, I am also in a hurry to the coachman. This is the mission of a fireman.
