Use a hashed connection to obtain optimal performance from a DB2 Universal DatabaseThe DB2 UDB optimizer can select different methods when executing connections: by default, it selects between nested loop join and merge join. When special environment variables are set, you can also select hash join ). Hash join can significantly improve the performance of some qu

The following articles mainly introduce the full contact of the DB2 driver types. We all know the related data access APIs provided by different versions of the database product line of IBM. It can be said that there are many data access APIs, these include early CLI-based Drivers, recent pure Java drivers, and combinations of CLI and Java. For a specific DB2 version, the driver has a specific driver and a

, Linux, OS/390, and z/OS, DBAs can better focus on DB2 management, instead of worrying about operating systems and platforms. Integrated DB2 Management Solution Quest central for DB2 provides a general database management solution for DB2 UDB running on Windows, UNIX, Linu

application B reads the new (updated) value of the row before committing the modification. If application A then "revokes" the update value (either through a SQL ROLLBACK statement in program logic, or because an error is automatically rolled back by DB2 UDB), application B's processing of the row is based on uncommitted (and possibly incorrect) data. While maintaining data integrity, the ability to provi

DB2 's DB2 cube views feature makes it easier to integrate business intelligence applications with data warehouses by sharing multidimensional metadata between relational databases and business intelligence applications. Learn how to enable business intelligence applications or tools to take advantage of this powerful new feature. This article applies to the object This article is intended for technical m

Today I saw a group of friends asked two questions comparison basis:1 How to confirm my DB2 is the root What about the installation? In fact, from DB2 UDB V9.1 have db2ls This command, the problem is much simpler, we just need to simply run down the db2ls, and then see the output of the Installer UID is 0(Root uid), as shown in:[[email protected] ~]$ db2lsinstall

. For applications based on DB2 UDB and php 4.x, IBM_DB2 is the best choice because it is optimized for DB2 UDB, at the same time, it avoids some compatibility problems that may exist when using the unified ODBC driver. However, IBM_DB2 only supports DB2 v8.2.2 or later. ◆ P

DSO mode. maintenance and upgrade in this mode are relatively simple. you can dynamically add new function modules as needed without re-compiling Apache. Of course, this will also bring about a decrease in the running efficiency, and the Apache server will slow down by about 20% at startup. There are also three ways for PHP to connect to the DB2 data source: uniied ODBC driver, IBM_DB2, and PDO (php data object ). ◆ The uniied ODBC driver is one of t

ODBC driver, IBM_DB2, and PDO (php data object ). ◆ The uniied ODBC driver is one of the earliest extension modules for PHP database access. Since DB2 v7.2, the unified ODBC driver supports access to it. For all databases that support ODBC, the unified ODBC driver provides a unified data access interface. To ensure the universality of interfaces, the unified ODBC driver does not perform specific optimization on different types of databases. ◆ IBM_DB2
