# EBCDIC collation for Db2 databases on Amazon RDS
<a name="db2-ebcdic"></a>

Amazon RDS for Db2 supports EBCDIC collation for Db2 databases. You can only specify an EBCDIC collation sequence for a database when you create the database by using the Amazon RDS [rdsadmin.create\$1database](db2-sp-managing-databases.md#db2-sp-create-database) stored procedure. 

When you create an RDS for Db2 DB instance by using the AWS Management Console, AWS CLI, or RDS API, you can specify a database name. If you specify a database name, Amazon RDS creates a database with the default collation of `SYSTEM`. If you need to create a database with EBCDIC collation, don't specify a database name when you create a DB instance.

The collation for a database in RDS for Db2 is set at the time of creation and is immutable.

**To create a Db2 database with EBCDIC collation**

1. If you don't have an RDS for Db2 DB instance, create a DB instance but don't specify a database name You can create a DB instance by using the AWS Management Console, AWS CLI, or RDS API. For more information, see [Creating a DB instance](USER_CreateDBInstance.md#USER_CreateDBInstance.Creating).

1. Create a Db2 database and set the collation option to an EBCDIC value by calling the `rdsadmin.create_database` stored procedure. For more information, see [rdsadmin.create\$1database](db2-sp-managing-databases.md#db2-sp-create-database).
**Important**  
After you create a database using the stored procedure, you can't change the collation sequence. If you want a database to use a different collation sequence, drop the database by calling the [rdsadmin.drop\$1database](db2-sp-managing-databases.md#db2-sp-drop-database) stored procedure. Then, create a database with the required collation sequence.
