In oracle10g, the default archive path is $oracle_base/flash_recovery_area. For this path, Oracle has a qualification that only 2G of space is available to the archive log by default, and you can use the following two SQL statements to view its qualification: 1. Select * from V$recovery_file_dest; 2. Show parameter db_recovery_file_dest (this friendlier and more intuitive) When the number of archived log

, tracking which nodes are part of the cluster, and deciding which shards to assign to the related nodes. A stable master node is very important to the health of the cluster.By default, nodes in any cluster may be selected as the primary node. Operations such as index data and search queries consume a large amount of CPU, memory, and IO resources, and in order to ensure a stable cluster, separating the master node and the data node is a good choice. Although the master node can also coordinate n

Explanation There is no CV qualifier, and in C + + the CV qualifier refers to const and volatile. Non-member function In C + +, normal functions (non-class member functions) cannot have CV qualification, that is, const and volatile qualification. That is, the number of member rows that are not classes, decorated with const: int Test () const//This is not true, normal functions (non-member functions c

I feel that although many people can make a member qualification management module, not many can do well. The management principles of this Member are unclear, and the implementation capability is not strong. In my opinion, to do a good job in member qualification management, we must first have a deep understanding of the concept and principles of member qualification
