DATA NOT NULL, CONSTRAINT taid_pk PRIMARY KEY (unique_val) )@ This process is implemented in C ++ and is used to access the asynchronous log reading API [4]. It uses embedded SQL to perform necessary SQL operations. The storage point is used to roll back the insert operation executed during the process to trigger write operations on log records. The SQL statements in this process can take

, which means that DB2 records the full log of index creation, rebuild, and reassembly. This obviously reduces the efficiency of the primary database and consumes more log space. However, because the standby database can re-build the index by replaying the log, the index of the standby database is still available when the primary database fails.You can set the index logging level for a single table by using the Log Index build option of the CREATE TAB

prevention of the LOAD operation may affect rollforward. Sometimes interactive operations are required in the rollforward process. If (t) is selected, the tablespace status is abnormal.

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.

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 Path level Fix Pack Special install number i

TabNameIf the file that holds the data is in the IXF format, no options are required for the load tool, and the conversion of the code page is completed automatically during data loading. If the load cannot succeed if the data format changes in the project that executes the code page conversion, the Forcein file modifier is used, and the example is as follows:Listing 4. Sample 2--IXF FileLOAD from Test ' IXF modified by Forcein inserts into TabNameNote: You can avoid this problem by choosing to

This article describes how to copy a DB2 table to a DB2 database through one-way Q replication. We all know that Q replication is a new high-speed technology, I is generally used to move data between databases managed by IBM DB2 Universal Database. It is a highlight of the just-released DB2 Information Integrator Versi
