How to Create a database Partition on a DB2 database?

The following article describes how to create a database Partition on a DB2 database. You can use the following command to create a db instance in the actual draft: db2icrt-s ESE-u db2admin, aaa123456-h anwenhao dbinstancename.

Create database partition

1. Create a db instance for which you need 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 the DB2 database.

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 will add a database partition and redistribution at this time.

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 the database Partition of the DB2 database to create cluster applications.
