This article mainly describes how to establish database Partition in DB2 and the related commands used in the operation, as we all know, to create a db instance that requires creating a database partition, run the following command to create a db instance:
- 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, You need to 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 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 DB2 database Partition to create cluster applications.
The above content is an introduction to the establishment of database Partition in DB2. I hope you will have some gains.
