DB2 notes-Common commands visual database management software can use DbVisualizer, suitable for multiple databases. 1. a tablespace is actually a way to organize data files. Oracle organizes data through the tablespace database object. Before inserting data into the Oracle database, you must first create a tablespace and then insert the data into an object in the tablespace. The best way to explain databases, tablespaces, data files, tables, and data
Today, we mainly describe the correct implementation of connecting SQL Server databases to the DB2 connection Server. We all know that the interconnection between different database platforms is generally called a heterogeneous service, currently, different databases can achieve such Heterogeneous Interconnection, but the specific implementation technologies of different vendors are different, such:
In SQL SERVER, it is called LINKED SERVER, and ODBC
online.
Or replace is added to multiple CREATE statements as an option.
CREATE with error support is added for views and inline SQL functions.
Added support for alter column set data type.
You can use the ADMIN_MOVE_TABLE routine to modify and move tables online.
Prerequisites and System Requirements
This article is specially written for the DB2 database administrator. You should understand the basic concepts of tablespaces, tables, and columns.
db2adutl and db2 list history to view backup records.
3) There is also a delta backup:

The difference between the two backups is similar to the Incremental and Cumulative modes of Oracle Exports. The incremental method of db2 corresponds to the cumulative mode of oracle, while the delta mode of db2 corresp

Install the database: sqlserver2000 (English version) and DB2 7.2 client (English version)
Specific steps:1. Install the DB2 client software and sqlserver2000 software on the PC.2. Configure the ODBC data source for Windows:Choose "start"> "program set"> "System Management Tools"> "Data
controlled by the database management program. This kind of tablespace is essentially a special-purpose file system implementation, which can best meet the needs of the database management program. · DMS Automatic Storage (Automatic Storage with DMS): auto-storage is not actually a separate tablespace type, but rather a different way of handling DMS storage. DMS containers require more maintenance, and automatic storage is introduced in DB2 V8.2.2 as
Looking at the DB2 tutorial is: DB2 common fool question 1000 q (i).
When you apply DB2, you may encounter some seemingly simple problems, especially for beginners, I have a simpleSummed up, released to everyone, I hope that we can help, but also welcome everyone to discuss together, common development and common progress!
The following are mainly based on db27.x
The configuration parameters in the DB2 Configuration Wizard are described in this article and examples of using the autoconfigure command for configuration are provided. DB2 version 8 provides a tool for automatic parameter configuration-Configuration Wizard. You can start the graphical interface configuration wizard in the control center or use the autoconfigur
It is a headache to uninstall a DB2 database. But it doesn't matter. The method for manually detaching A DB2 database described below may solve your problem.
Manually uninstall the DB2 database:
The following method is applicable when the Windows Installer Cannot uninstall DB2 and the "Force Delete" method of a colleag
validity. This is usually something else, but should be used in real parent-child relationship.
8. A table can contain at most one or two indexes.
Actual: The table should have multiple indexes according to performance requirements.
9. Non-partitioned indexes (NPI) should not be used, especially in large tables.
Actually: this is related to countless problems, which can be overcome in general, but NPI is necessary for proper access and performance.
10. Large tables should be split
Actually: bec
difficulty is that SQL is often used as an I/O processor rather than a collection processor.
7. The code and reference table should be used together with the referential integrity (RI) declared by DB2.
Actually, RI should not be used as a shortcut for editing validity. This is usually something else, but should be used in real parent-child relationship.
8. A table can contain at most one or two indexes.
Actual: The table should have multiple indexes
In the management of DB2, you may need to modify the Host Name of the DB2 database server. I will instruct you to modify the Host Name of the DB2 server.
Product: DB2 UDB
Platform: AIX, Solaris, HP-UX, Linux, Windows
Version: V8 V9.1V9.5
To modify the server host name, perfo
Download revision package
DB2 does not require different levels of revision packages to be installed one by one. Higher-Level revision packages contain all the code in the lower-level revision packages, so you can select the most current-Level revision packages for download.Download location: ftp://ftp.software.ibm.com/ps/products/db2/fixes/

The main differences between DB2 and ORACLE SQL notation
To be honest, Oracle has spoiled the country's programmers, and SQL in the code is flooded with Oracle features, and almost no one knows what ANSI's standard SQL looks like, leaving the program out of Oracle at all, and the situation has changed dramatically with hibernate.DB2 as the choice of many international major customers (said the world's top 500 80% with
DB2 index and concurrency analysis before DB2 V9.7 or if the CC feature is not enabled for DB2 V9.7, if the query scans records that are being inserted or modified, the query will be suspended, until the session of the modification record is submitted or rolled back.

, and deploy DB2 storage processes and user-defined functionality. Customers can also use Developer Workbench to develop SQL applications, create, edit, and run SQL statements and XML queries.The enhanced DB2 driver for JDBC and SQLJ conforms to the JDBC 3.0 specification and also supports SQLJ statements.
The functional characteristics of the SQLJ statement are similar to those of most JDBC methods.Also i

3, create the database

4, delete the database
Be careful to do this.
