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

Oracle ORA-00001: violation of unique constraints and ORA-00054: Resource busy error resolution, ora-00001ora-00054 Oracle databases may report errors for common errors. During the year of work, some errors have been encountered and some pitfalls have been encountered. Thanks to the questions and solutions shared by those predecessors, just as the Chinese New Year is not busy these days, I will describe some errors, analyze the causes and solutions,

When you recently used the Oraclede IMPDP tool to import a database, the following occurs when using the database.[null] [17081]; Error in batch: Ora-00001 is java.sql.BatchUpdateException: Error occurred in batch: Ora- 00001 -(:155)Because the ID of the table is unique, this is the case with select Max (ID) from test that is larger than the start ID in sequences.To do this, we just change the "start in" I

However, it is strange that the violation constraint prompted in the error is an index

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

How can I disable the P2P shared update function? After Win10 is updated, P2P sharing leads to 100% CPU usage and p2pwin10 During the use of the computer, sometimes there will be an instant high CPU usage problem, this may be due to the enabling of P2P Sharing updates, the benefits of P2P Sharing updates needless to s

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

With the rapid development of P2P applications, the discovery technology, as the core issue of P2P applications, not only follows the logic of the technology itself, but also is profoundly influenced by the development trend and Demand Trend of some technologies. -As mentioned above, the DHT discovery technology is fully built on the basis of a deterministic topology structure, which demonstrates guidance o

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

message. 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

Introduction: P2P (peer-to-peer) is a technology, but it is more of an idea that has the potential to change the entire Internet base. On the eve of the mobile value-added business era, P2P and grid technologies, POC, and ad. like other technologies such as hoc, it seems that investors are full of hope, and the plum blossom in the word of Su Shi is hard to see. Why is
