ORA-00001: unique constraint violated Solution

ORA-00001: unique constraint violated solved the error of inserting data into the database today: www.2cto.com ORA-00001: unique constraint (IDX_CARTON_HEADER) violated. that is to say, when inserting data into CARTON_HEADER, there is a unique constraint in the column. The value of the column to be inserted is the same as the value of the original column in the database. Therefore, an error is returned to c

Understanding P2P, using P2P

It is the abbreviation of peer-to-peer (it seems that I have also seen the article saying "Point to Point". I am not clear about it, or I am depressed about the online materials ), PEER has meanings in English, such as "(status, ability, etc.) equal person", "colleague", and "partner. In this way, P2P can be understood as "peer-to-peer", or "Peer-to-Peer Networking. At present, people think that it has a bright future in strengthening the communicatio

The latest ESFramework/ESPlus version provides TCP and UDP-Based P2P channels, whether we use TCP-based P2P channels or UDP-Based P2P channels, ESPlus ensures that all P2P communication is reliable. This is because ESPlus re-encapsulates the TCP mechanism based on the original UDP to make UDP as reliable as TCP. In dis

The topological structure refers to the physical or logical interconnection between computing units in a distributed system. The Topological Structure between nodes has always been an important basis for determining the system type. Currently, centralized and hierarchical topologies are widely used in interconnected networks. Interne is the world's largest non-centralized interconnected network, however, some network application systems established in 1990s are completely centralized, and many w

Author: gnuhpcSource: http://www.cnblogs.com/gnuhpc/ A common problem of P2P is how to efficiently locate a node. That is to say, how can a node efficiently know which node in the network contains the data it is looking for? For example: There are three typical solutions to this problem. Napster: uses a central server to receive all queries, and the server tells where to download the required data. The problem is that a single point of failure on the

When you get rid of the message receiving bean deployed in JBoss and then send the message at this time the message is in the queue and once you redeploy he will immediately receive the message just sent so it has no time dependency, pub/sub models can have multiple consumers in this model if we define multiple beans that receive messages when we send a message to the client, two beans will receive the message, so he has multiple consumers but If you remove the message receiving bean
