Command description for creating a DB2 database partition

This article describes how to create partitions in a DB2 database. This article describes how to create database partitions in a DB2 database and related commands, the following is a detailed description of the main content of the article. I hope you will have a better understanding of it after browsing.

Create database partition

1. Create a db instance for which you need to create a DB2 database partition

You can run the following command to create a db instance:

 
 

  
  
db2icrt -s ESE -u db2admin,aaa123456 -h ANWENHAO DBINSTANCENAME 
 
 

After creating the corresponding instance, restart DB2.

2. Add the new db instance to DB2:

 
 

  
  
CATALOG LOCAL NODE DB2INST1 INSTANCE DB2INST1 SYSTEM ANWENHAO OSTYPE NT; 
 
 

3. In the command line, set the dbInstance to be operated in the DB2 database partition.

 
 

  
  
set db2instance=db2inst1 
  
  
db2 get instance  
  
  
db2 attach to db2inst1  
 
 

4. Create DBPartition

 
 

  
  
db2start dbpartitionnum 1 ADD DBPARTITIONNUM HOSTNAME ANWENHAO PORT 1  
  
  
COMPUTER ANWENHAO USER db2admin PASSWORD aaa123456 WITHOUT TABLESPACES  
 
 

5. After creation, you need to restart db2. DB2 adds a database partition and performs redistribution.

The preceding operation completes database partition.

Create database partition group

 
 

  
  
CREATE DATABASE PARTITION GROUP "NODE1" ON DBPARTITIONNUMS (1);  
  
  
COMMENT ON DATABASE PARTITION GROUP "NODE1" IS 'ANWENHAO _1';  
 
 

Then, you can select whether to create a table space in a database partition group. In this way, we can easily use DB2 database Partition to create cluster applications.

The above content is an introduction to the establishment of DB2 database partitions. I hope you will have some gains.
