I finally had a holiday. I came back from class today and became a monk at Shaolin Temple. like a Wooden bucket, I moved a lot of shoes to the rented warehouse in a box. This warehouse is also rented for 9600 yuan a year. My OCP's future OCM will often help my wife with shoes. It seems that I am a man listening to my wife. On May Day, we need to move the shoes on the fifth floor to the warehouse on the first floor and the store. It seems that this holiday is really Labor Day and manual work. It's just exercise.
Let's get down to the truth. GC and grid control. Let me describe it.
GC is an Oracle application used to manage and monitor all services and resources in the grid. Various services and resources in the grid include database servers, application servers, hosts, and so on.
GC is a three-tier application system. The background is a database, of course, it must be an Oracle database. This database is OMR.
Similar to the RMAN database, it is actually a bunch of database objects for application GC. The middleware is Oracle IAS
It is an Application server of Oracle. This application server is not selling well, so the GC of oracle11g version is changed to weblogic. On the Application Server
Above, a lot of applications are run, these applications are the real GC, the real OMS.
To manage the target resources and services, we must install a proxy Oma on these resources and services. Agent, which can be translated as an agent, an agent, a spy, or a Trojan. From derogatory to derogatory, the function of OMA has not changed, so we can see what is used for, use regular expressions, and use evil spirits.
I didn't think that the first course of OCM was actually used by Oracle to promote an application of OCM. It also included a database, a middleware, and a spy. This class of foreign devils will also really drill into the camp. In fact, we should face this matter with a positive attitude, at least let us have a deep understanding of the application of the three-tier architecture, broaden the knowledge. For a person's life, we can't just engage in databases, time, energy, talents, or put them in multiple baskets. Oracle database is a good way to cool up wisdom, I have thoroughly studied this and mastered the learning methods,
It is easy to learn other things in the way of thinking.
From the perspective of enterprise management, the current human resources are still relatively low, and several DBAs are hired more, and hundreds of databases are managed, especially outsourcing services, which are more cost-effective, DBA is saved. It's a waste of money to buy GC.
GC, I only read chapter 8. Maybe I can't understand it deeply. I have a deep understanding only when I have played many things. I hope that you can take a picture and make progress.
