For environments that contain N DB2 database subsystems, either through the z/OS console or z/OS applications. If you want to execute DB2 commands in a specific DB2 system, you must use the command prefix, for example,-DSN1 dis group details. All DB2 commands can be executed.

The following articles mainly describe how to correctly execute DB2 commands. If you encounter DB2 commands in actual operations, but you do not know how to solve them correctly, so the following articles must be good teachers and friends for you.
You can use the z/OS console or z/OS applications for environments that contain multiple execution DB2 subsystems. I

Wang feipeng: There are two phases to look at this problem. Before DB2 V97, DB2 and ORACLE went further and further in terms of architecture, design, and development.
However, after DB2 97, there was a "watershed". DB2 and ORACLE were getting cl

InDB2 databaseDuring maintenance, some work may need to be processed frequently. For example, before the database is put into production and use, a large amount of information needs to be created in the database. This step is done by importing data directly from a file to the database system.
Prior to data import, the DB2 database system often checks the format of external files carefully. If the format of the external file does not meet the mandatory

We all know that in the maintenance of the Oracle DB2 database, There is a related task that we often need to deal. If we need to create a large amount of information in the relevant database before putting it into practical production and use in the Oracle database. This step is done by importing data directly from a file to the database system.
