This article describes how to easily master the actual operation steps of database memory protection in DB2 9.5. in DB2 9.5, the database engine changes from the process mode to the thread mode, which means that the entire database engine is in an address space (any code segment can access any global variables ). This naturally has both advantages and disadvantag

Structured Query Language (SQL) is a double-edged sword for relational DBMS, whether DB2 or Oracle, SQL Server database, and has mixed advantages and disadvantages. Because SQL is required to retrieve any data from a relational database, the topic of this article is how they will access a relational database, whether they are end users or developers or database administrators (DBAs). When efficient SQL is u

tablespace is divided into system temporary tablespace and user temporary tablespace. The system temporary tablespace is used to store the internal temporary data required in various data operation sorting, table reorganization, index creation, and table connection). Although you can create any number of system temporary tablespaces, however, we recommend that you only create one table with the page size used by most tables. The default temporary tablespace name is TEMPSPACE1. The user temporar

We often see DB2 table join operations. The following describes the principle of DB2 table join in detail. If you are interested in this, take a look. In DB2, the optimizer can select nested connections or merge connections. If correct, you can also select hash connections. If the system is properly tuned, hash connections can significantly improve the performanc

Comparison of concurrency control (LOCK) between DB2 and Oracle Comparison of concurrency control (LOCK) between DB2 and Oracle 1 Introduction The minimal recovery and transaction units in relational databases (DB2, Oracle, Sybase, Informix, and SQL Server) are a transaction (Transactions). Transactions are ACID (atomicity, consistency, isolation, and durability

they cannot be used as partition keys. Collocated Collocation is used to place rows in different tables in the same database partition that contain relevant data. The parallel table enables DB2 to use the connection policy more effectively. You may find that as a response to a specific query, two or more tables provide data frequently. In this case, you want the data in such a table to be as close as possible. In an environment where a database is ph

This ability to locally execute connections or subqueries has significant performance advantages. To enable the coexistence of DB2 databases, tables must: In the same database partition
