Basic ideasThe basic idea of this method is that the whole sequence of elements is divided into several sub-sequences (consisting of elements separated by an "increment"), then the direct insertion sort is done separately, then the increment is reduced and then sorted, and then the whole element is sorted by a direct insertion when the elements in the entire sequence are basically ordered (the increment is small enough).StabilityBecause of the number

: Network Disk DownloadIntroduction DB2 database is the core product of IBM's relational database, and it is widely used both domestically and globally. For DB2 beginners, the "Step DB2:DBA system Management, operation and application case" gradually introduced the many concepts and knowledge DB2 involved to everyone.
DB2 supports Incremental Backup (Incremental Backup) and Delta Backup (Delta Backup. incremental backup is equivalent to a differential backup in Oracle, that is, after a full backup, all the changes since the full backup are backed up for each other Incremental backup. delta backup is equivalent to Incremental Backup in Oracle. Each Incremental Backup only backs up the incremental parts since the previous backup. A detailed Incremental Backup example

TermsBefore discussing DB2's support for 32-bit and 64-bit, we will first view and understand some of the terms and important concepts involved in the context of this article. This is very important:
Platform:The basic technologies of computer hardware and operating systems define how a computer runs and what kind of software can run on it.
Hardware:Computer and its related architecture.
Operating System:Controls computer hardware and allows other
This article mainly introduces some similarities between DB2 database development and PostgreSQL development in actual operations. What's more, I recently used DB2 databases and wrote some differences between them. Not necessarily true. But you can see the difference between the two.

1. display the db2setup command in a local languageThe db2setup command is used to query the operating system to determine the existing language settings. If db2setup supports language settings on the operating system, this language is used.If your system uses the same code page as the DB2 interface, but the language environment name is different from the supported language environment name, run the

1. Basic IdeasHill sort is to group records by a certain increment of the subscript, sorting each group using the direct insertion sorting algorithm; As the increments gradually decrease, each group contains more and more keywords, when the increment is reduced to 1 o'clock, the entire file is divided into a group, the algorithm terminates.2. Principle of ImplementationFor N ordered series, take an integer less than n (Gap is called step) to divide th
I feel that the answers to many basic questions can be obtained through the help of DB2, because DB2 itself has very detailed help information after installation, so I think it is necessary to summarize how to get help from the DB2 command syntax!

On any workstation platform that supports DB2 UDB, MTK supports database conversion from Sybase 11.9.2 and Microsoft SQL Server 6.5 and 7.0 to DB2 UDB version 7.2 and higher. For versions earlier than Sybase V11.x and earlier than ms SQL Server V7.0, MTK can also be used to convert scripts imported from these databases. MTK does not support sending data to DB2 UD

The DMS needs to manually specify the file name of the container and stored data, and ensure that sufficient disk sp
Tags: DB2 database deadlock lock timeoutanalysis and explanation of DB2 lock problemLock timeouts and deadlocks are often encountered in DB2 applications, so what is the cause of this phenomenon? In this paper, the phenomenon of lock waiting, lock time-out and deadlock is simulated in the form of experiment, and the root cause of these phenomena is given.Test env
Through the previous section of the study, we learned how to use @query annotations to achieve a flexible query. In the example in the previous section, I also tried to give a simple sort, with JPQL statements and native SQL. This implementation, although to some extent can be applied, but not enough flexibility, so in conjunction with @query annotations, we can use sort to

Terminates the specified connection handle and the transaction is interrupted and rolled back. Manipulating multiple handles at the same time can be separated by commas or by specifying the keyword all. This command terminates only the specified connection and does not prevent new applications from connecting to the database.
