Introduction This seriesArticleIn the previous article, I gave an overview of what replication is. This article describes several common replication modes based on the organization and replication types of the Publishing Server, distribution server, and subscription server. Mode Selection The replication mode depe
So far, we have processed file-based replication (or log shipping) and simple stream-based replication settings. In both cases, after the transaction is committed on master, the data is submitted and received by slave. It will still be lost at the time that master commits and slave actually receives the data completely.In this chapter, we will study the following topics:• Ensure that no transactions are los
feature that ensures that organizations can take advantage of XML functionality in a native way. With the DB2 express-c 9 PureXML feature, you no longer need to store documents in large objects (lobs) or to break them into objects. Although IBM DB2 Express-c is well-suited to the needs of small and midsize enterprises, it does not provide all the features available in later versions.

IntroducedOne important feature of Meta compared to Kafka is the implementation of the message high availability scenario, which we call the HA scenario. The message is written to the disk immediately after it is sent to the broker and returned to the client to tell the producer that the message was sent successfully, and the control of the unflushThreshold unflushInterval two parameters can guarantee the security of the stand-alone message data, as long as the machine's disk is not permanently
PostgreSQL replication cluster overview, PostgreSQL replication Cluster For pg replication, high availability, and load balancing clusters, write an overview for future reference. Pg has the following various replication-Based Cluster solutions, most of which were used, and some were not sorted out at the time. There
In the process of DB2 development, one of the most important tasks throughout the development process is the maintenance of the database, which is necessary to maintain a large information system; Leave a simple maintenance manual for a rainy year; The following parts of the maintenance order are collected to treat our maintenance engineers and project managers. * update:2006-06-14 * Memo: Please use "
doing very well, guaranteeing a flexible and highly available mechanism. DB2 combined with GPFS is a great solution, but after all, GPFS is a container for DB2 after file system mapping, and performance is not as straightforward as ASM. Personal understanding.View Three (Oracle),ASM realizes the automatic management and optimization of the host level file system, bare devices and other storage resources, w
The DB2 tutorial you're looking at is: DB2 data synchronization experience. Planning programme: Assume that you will use a report-generating application. This application requires data that exists in the DEPARTMENT table of the SAMPLE database. Instead of using data that comes directly from the source table, you want to copy the changes to the target table that can only be read by the application that gener

database, I think we should first understand the CD table. This is also a unique identifier in DB2 databases. The clustered target table is created based on the CD table. In DB2 databases, data replication functions similar to other databases can be implemented. That is, data can be copied and synchronized between the source database and the reservation integrat
