It is easy to set up database Partition correctly on the DB2 database!

The following articles mainly describe the actual operation steps for correctly establishing database Partition on the DB2 database. If you are interested in the operation steps for correctly establishing database Partition on the DB2 database, you can click to view the following articles.

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, You need to restart DB2.

2. Add the new db instance to DB2:

 
 

  
  
CATALOG LOCAL NODE DB2INST1 INSTANCE DB2INST1 SYSTEM ANWENHAO OSTYPE NT; 
 
 

3. To create a database Partition on a DB2 database, you must set the dbInstance to be operated on 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.
