What commands are used to create database partitions in DB2?

If you are curious about how DB2 creates database partitions, this article will unveil its mysteries, this article describes how to correctly create database partitions and related commands on a DB2 database for your reference.

Create database partition

1. Create a db instance that requires DB2 to create a 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. Set the dbInstance to be operated in the command line.

 
 

  
  
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';
