The following articles mainly describe the actual operation solution for DB2 data replication and migration. The following method is tested by professionals in the Environment IBM x346, in 3.2G × 2, 4G, RAID 1, DB2 V8.2.4, Win2000 Adv Server, and DMS tablespaces, the data load speed is about 60-entries/min. Background:You need to change the tablespace of the data

Data replication between tables We can use insert between two tables to implement simple replication (the two tables have the same structure). The example is as follows: SQL> create table T (2 tid number (4 ), 3 tname varchar2 (10) default 'abc ', 4 tbirthday date default sysdate ); The table has been created. SQL> insert into T values (1, 'aaa', '05-January 1,

The benefits of using MySQL master-slave replication are: 1, the use of the master-slave server architecture, stability can be improved. If the primary server fails, we can use the server to provide services;2, in the master and slave server separately processing user's request, may enhance the data processing efficiency;3. Copy the data from the primary server

structure and data to a new table SELECT * into from Original table name We copy the structure and data of the table test to the new table test1: SELECT * into from Test The results are as follows: 2. Back up part of the table column (do not write * and write out the list of columns) SELECT into from the original table name We copy the data from the tab

Data backup and Database Replication in Oracle user management mode The first thing to note is that Oracle Database Backup can be divided into logical backup and physical backup. Logical backup backs up data through data export, mainly through the old IMP/EXP and Data Pump l

Setting up MYSQL Data synchronization MySQL provides database replication functionality after version 3.23.15. The function of two database synchronization, master-slave mode and mutual backup mode can be realized by this feature. The settings for database synchronization replication are reflected in the MySQL settings file. MySQL's configuration file (typically

Today I have a general understanding of the Dell Shareplex data replication software, the URL is: http://software.dell.com/products/shareplex/As you can see from this URL,Shareplex as the source, supporting only Oracle DB,Shareplex as the destination, supported as follows: Oracle, Microsoft? SQL Server?, SAP? ASE, Hadoop?, Java? Message Service (JMS), SQL and XML FilesHVR compared with Shareplex, the advant

You may be running an Oracle 10g Release 2 database server, but supporting some applications may have been written very early. Data tables created prior to Oracle 8i typically have a long data type to store large text. With the introduction of the large Object (LOB) data type, the long and long raw data types are disc

To ensure the reliability of the storage file, HDFs decomposes the file into multiple sequence blocks and saves multiple copies of the data block. This is important for fault tolerance, where a copy of a block of data can be read from another node when one of the data blocks of the file is corrupted. HDFs has a "rack-aware" strategy for placing a copy of the fil

Normally, copying and backing up tables is usually done directly by the IDE. But sometimes, some initialization of the data script, before operating the data, it is best to back up the structure of the Operation table, data, not error is placed in a dilemma.So the statement that replicates the table structure and table data
