TCP connection scanning, based on sockets, uses threading to implement multi-threading and to control the number of processes.Note: The Threads_limit variable depends on the host, and there are too many definitions to make the following error:650) this.width=650; "Src=" Http://s2.51cto.com/wyfs02/M00/86/F2/wKiom1fPfPGTqgnjAAAL7L75bGQ904.png-wh_500x0-wm_3 -wmp_4-s_3950277187.png "title=" 1.png "alt=" Wkiom1fpfpgtqgnjaaal7l75bgq904.png-wh_50 "/>Code:Importsocketimportthreading#changethesevars.star

normal, we will find the answer on metalink. Cause: Metalink Description: Client is able to resolve all Fully Qualified Domain Name (FQDN) SCAN and VIP name but not short ones (without domain name) as its in different domain;Even though FQDN names were specified during Grid Infrastructure setup, due to bug 9150053 by default DBCA set database parameter local_listener to short node VIP name while database is created. Therefore, you only need to change

Create a Windows application and use multiple threads to scan a computer in a CIDR block. Obtain the DNS domain name based on the IP address of the computer. If the computer is not online, a prompt is returned. The initial interface is required. After you enter the IP address range, click scan to automatically display

If your cluster has four nodes, the client's tnsnames. in ora, there should be a connection string of four vip hosts. If a node is added to the cluster, You need to modify the tnsnames for each client connected to the database. ora. After scan is introduced, it facilitates an interface for client con
