and understanding these differences in advance will help prevent and solve problems encountered during database recovery. The following describes the operation methods and related commands for redirect recovery and rollback respectively. The system automatically generates a redirection recovery script and a redirection recovery status query command to extract the database redirection recovery script from a database backup file. For example,/db2_backup/db2inst1/sample is the directory where the

This part is simple and clear at a glance. Five different permission levels: sysadm, sysctrl, sysmaint, dbadm, and loadBut I have read that there is sysmon in CFG, which may be mentioned later (to obtain access to database system monitor data)Or the version is not updated. The following aspects of the DB2 authorization control database security plan:* Permission level granted to a user* Commands that can be run by users* Allows users to read and/or m

Working schematics for DB2 Hadr:Note: The database in the standby role cannot be accessed.Let's start with a configuration example to understand the basic configuration process of the DB2 HADR environment, and then discuss some of the technical points that are involved in the

than the intermediate Windows machine with MTK installed. Figure 4. Use batch files for deployment The following describes the five iteration steps on the MTK interface: Step 1: Specify the source After creating or opening a migration project, you can start the migration process. Your first step is to obtain the DDL source file to be converted to DB2. This step is completed on the Specify Source Page. U

LOAD tool is always unable to execute, regardless of the option specified. The LOAD tool does not execute until the query for the target table finishes.If the query against the target table is executed after the load tool is first executed and the query is executed while the load tool is running, the query statement can be executed as soon as the load tool specifies the Allow Read access option.So the load utility is not a good tool, and the best way to use the Import tool instead of the load t

Fortunately, DB2 provides the related USEREXIT Program (also known as the user exit Program), which allows us to manage log files and has the possibility of extended functions. At this point, DB2 is obviously better than Orac. Fortunately, DB2 provides the related USEREXIT Program (also known as the user exit Program), which allows us to manage log files and has

The following article describes how to create a second DB2 instance in the command line status in the DB2 database under the linux operating system, the following describes the actual operation steps for creating a DB2 instance. We hope this will help you in your future study. In DB2 in linux, create the second

DB2 has three main security mechanisms to help DBAs implement database security plans: Authentication, authorization, and privilege ). Five different permission levels: sysadm, sysctrl, sysmaint, dbadm, and load A new concept in DB2 9 is tag-based access control (lbac) that allows control of who has the right to access individual rows and/or columns.
