Manually configure master databases

Overview of manual split database configuration

If the Magento application is already in production or if you’ve already installed custom code or components, you might need to configure split databases manually. Before continuing, contact Magento Support to see if this is necessary in your case.

Manually splitting databases involves:

Create the checkout and order management system (OMS) databases
Run a series of SQL scripts that:
- Drop foreign keys
- Back up sales and quote database tables
- Move tables from your main Magento database to the sales and quote databases

If any custom code uses JOINs with tables in the sales and quote databases, you cannot use split databases. If in doubt, contact the authors of any custom code or extensions to make sure their code does not use JOINs.

This topic uses the following naming conventions:

The main Magento database name is magento and its username and password are both magento
The quote database name is magento_quote and its username and password are both magento_quote

The quote database is also referred to as the checkout database.
The sales database name is magento_sales and its username and password are both magento_sales

The sales database is also referred to as the order management system (OMS) database.

This guide assumes all three databases are on the same host as the Magento application. However, the choice of where to locate the databases and what they’re named is up to you. We hope our examples make the instructions easier to follow.

Back up the Magento system

We strongly recommend you back up your current database and file system so you can restore it later in the event of issues during the process.

Click to show how to back up Magento

To back up your system:

Enter the following commands:

magento setup:backup --code --media --db

Continue with the next section.

Set up additional master databases

This section discusses how to create database instances for sales and quote tables.

Click to show how to create database instances

Create sales and OMS quote databases as follows:

Log in to your database server as any user.
Enter the following command to get to a MySQL command prompt:
```
1
mysql -u root -p
```
Enter the MySQL root user’s password when prompted.

Enter the following commands in the order shown to create database instances named magento_quote and magento_sales with the same usernames and passwords:

create database magento_quote;
GRANT ALL ON magento_quote.* TO magento_quote@localhost IDENTIFIED BY 'magento_quote';

create database magento_sales;
GRANT ALL ON magento_sales.* TO magento_sales@localhost IDENTIFIED BY 'magento_sales';

Enter exit to quit the command prompt.

Verify the databases, one at a time:

quote database:

mysql -u magento_quote -p

exit

mysql -u magento_quote -p

mysql -u magento_sales -p

exit

If the MySQL monitor displays, you created the database properly. If an error displays, repeat the preceding commands.

Continue with the next section.

Configure the sales database

This section discusses how to create and run SQL scripts that alter quote database tables and back up data from those tables.

Sales database table names start with:

salesrule_
sales_
magento_sales_
The magento_customercustomattributes_sales_flat_order table is also affected

This section contains scripts with specific database table names. If you’ve performed customizations or if you want to see a complete list of tables before you perform actions on them, see Reference scripts.

For more information, see:

Create sales database SQL scripts
Back up sales data

Create sales database SQL scripts

Click to create and run sales database SQL scripts

Create the following SQL scripts in a location that is accessible by the user as whom you log in to your Magento server. For example, if you log in or run commands as root, you can create the scripts in the /root/sql-scripts directory.

Remove foreign keys

This script removes foreign keys that refer to non-sales tables from the sales database.

Create the following script and give it a name like 1_foreign-sales.sql. Replace <your main Magento DB name> with the name of your Magento database.

use <your main Magento DB name>;

Configure the sales database

Run the preceding script:

At the mysql> prompt, run the script as follows:

source <path>/<script>.sql

For example,

source /root/sql-scripts/1_foreign-sales.sql

After the script run, enter exit.

Back up sales data

This section discusses how to back up sales tables from the main Magento database so you can restore them in the separate sales database.

Click to back up and restore sales data

If you’re currently at the mysql> prompt, enter exit to return to the command shell.

Run the following mysqldump commands, one at a time, from the command shell. In each, substitute the following:

<your database root username> with the name of your database root user
<your database root user password> with the user’s password
<your main magento DB name> with the name of your Magento database
<path> with a writable file system path

Script 1

mysqldump -u <your database root username> -p <your main magento DB name> sales_bestsellers_aggregated_daily sales_bestsellers_aggregated_monthly sales_bestsellers_aggregated_yearly sales_creditmemo sales_creditmemo_comment sales_creditmemo_grid sales_creditmemo_item sales_invoice sales_invoice_comment sales_invoice_grid sales_invoice_item sales_invoiced_aggregated sales_invoiced_aggregated_order sales_order sales_order_address sales_order_aggregated_created sales_order_aggregated_updated sales_order_grid sales_order_item sales_order_payment sales_order_status sales_order_status_history sales_order_status_label sales_order_status_state sales_order_tax sales_order_tax_item sales_payment_transaction sales_refunded_aggregated sales_refunded_aggregated_order sales_sequence_meta sales_sequence_profile sales_shipment sales_shipment_comment sales_shipment_grid sales_shipment_item sales_shipment_track sales_shipping_aggregated sales_shipping_aggregated_order > /<path>/sales.sql

Script 2

mysqldump -u <your database root username> -p <your main magento DB name> magento_sales_creditmemo_grid_archive magento_sales_invoice_grid_archive magento_sales_order_grid_archive magento_sales_shipment_grid_archive > /<path>/salesarchive.sql

Script 3

mysqldump -u <your database root username> -p <your main magento DB name> magento_customercustomattributes_sales_flat_order magento_customercustomattributes_sales_flat_order_address > /<path>/customercustomattributes.sql

Script 4

mysqldump -u <your database root username> -p <your main magento DB name> sequence_creditmemo_0 sequence_creditmemo_1 sequence_invoice_0 sequence_invoice_1 sequence_order_0 sequence_order_1 sequence_rma_item_0 sequence_rma_item_1 sequence_shipment_0 sequence_shipment_1 > /<path>/sequence.sql

Restore sales data

This script restores sales data in your quote database.

NDB requirement

If you are using a Network Database (NDB) cluster:

Convert tables from InnoDb to NDB type in dump files:

sed -ei 's/InnoDb/NDB/' <file name>.sql

Remove rows with a FULLTEXT key from dumps because NDB tables do not support FULLTEXT.

Restore the data

Run the following commands:

mysql -u <root username> -p <your sales DB name> < /<path>/sales.sql

mysql -u <root username> -p <your sales DB name> < /<path>/sequence.sql

mysql -u <root username> -p <your sales DB name> < /<path>/salesarchive.sql

mysql -u <root username> -p <your sales DB name> < /<path>/customercustomattributes.sql

where

<your sales DB name> with the name of your sales database.

In this topic, the sample database name is magento_sales.
<root username> with your MySQL root username
<root user password> with the user’s password
Verify the location of the backup files you created earlier (for example, /var/sales.sql)

Configure the quote database

This section discusses tasks required to drop foreign keys from sales database tables and move tables to the sales database.

Quote database table names start with quote. The magento_customercustomattributes_sales_flat_quote and magento_customercustomattributes_sales_flat_quote_address tables are also affected

Drop foreign keys from quote tables

This script removes foreign keys that refer to non-quote tables from quote tables. Replace with the name of your Magento database.

Click to drop foreign keys from quote tables

Create the following script and give it a name like 2_foreign-key-quote.sql:

use <your Magento main DB name>;
ALTER TABLE quote DROP FOREIGN KEY QUOTE_STORE_ID_STORE_STORE_ID;
ALTER TABLE quote_item DROP FOREIGN KEY QUOTE_ITEM_PRODUCT_ID_CATALOG_PRODUCT_ENTITY_ENTITY_ID;
ALTER TABLE quote_item DROP FOREIGN KEY QUOTE_ITEM_STORE_ID_STORE_STORE_ID;

Run the script as follows:

At the mysql > prompt, run the script as follows: source <path>/<script>.sql

For example,

source /root/sql-scripts/2_foreign-key-quote.sql

After the script runs, enter exit.

Back up quote tables

This section discusses how to back up quote tables from the main Magento database and restore them in your quote database.

Click to back up and restore quote tables

Run the following command from a command prompt:

mysqldump -u <your database root username> -p <your main Magento DB name> magento_customercustomattributes_sales_flat_quote magento_customercustomattributes_sales_flat_quote_address quote quote_address quote_address_item quote_item quote_item_option quote_payment quote_shipping_rate quote_id_mask > /<path>/quote.sql;

NDB requirement

If you are using a Network Database (NDB) cluster:

Convert tables from InnoDb to NDB type in dump files:

sed -ei 's/InnoDb/NDB/' <file name>.sql

Remove rows with a FULLTEXT key from dumps because NDB tables do not support FULLTEXT.

Restore tables to the quote database

mysql -u root -p magento_quote < /<path>/quote.sql

Drop sales and quote tables from the Magento database

This script sales and quote tables from the Magento database. Replace with the name of your Magento database.

source <path>/<script>.sql

For example,

source /root/sql-scripts/3_drop-tables.sql

After the script runs, enter exit.

Update your deployment configuration

The final step in manually splitting databases is to add connection and resource information to Magento’s deployment configuration, env.php.

Click to update the Magento deployment configuration

Back up your deployment configuration:

cp <magento_root>/app/etc/env.php <magento_root>/app/etc/env.php.orig

Open <magento_root>/app/etc/env.php in a text editor and update it using the guidelines discussed in the following sections.

Update database connections

Locate the block starting with 'default' (under 'connection') and add 'checkout' and 'sales' sections. Replace sample values with values appropriate for your site.

 'default' =>
      array (
'host' => 'localhost',
'dbname' => 'magento',
'username' => 'magento',
'password' => 'magento',
'model' => 'mysql4',
'engine' => 'innodb',
'initStatements' => 'SET NAMES utf8;',
'active' => '1',
      ),
      'checkout' =>
      array (
'host' => 'localhost',
'dbname' => 'magento_quote',
'username' => 'magento_quote',
'password' => 'magento_quote',
'model' => 'mysql4',
'engine' => 'innodb',
'initStatements' => 'SET NAMES utf8;',
'active' => '1',
      ),
      'sales' =>
      array (
'host' => 'localhost',
'dbname' => 'magento_sales',
'username' => 'magento_sales',
'password' => 'magento_sales',
'model' => 'mysql4',
'engine' => 'innodb',
'initStatements' => 'SET NAMES utf8;',
'active' => '1',
      ),
    ),

Update resources

Locate the block starting with 'resource' and add 'checkout' and 'sales' sections to it as follows:

'resource' =>
  array (
    'default_setup' =>
    array (
      'connection' => 'default',
    ),
    'checkout' =>
    array (
      'connection' => 'checkout',
    ),
    'sales' =>
    array (
      'connection' => 'sales',
    ),

Reference scripts

This section provides scripts you can run that print a complete list of affected tables without performing any actions on them. You can use them to see what tables are affected before you manually split databases, which can be useful if you use extensions that customize the Magento database schema.

Click to view reference SQL scripts

To use these scripts:

Create a .sql script with the contents of each script in this section.
In each script, replace <your main magento DB name> with the name of your Magento database.

In this topic, the sample database name is magento.
Run each script from the mysql> prompt as source <script name>
Examine the output.
Copy the result of each script to another .sql script, removing the pipe characters (|).
Run each script from the mysql> prompt as source <script name>.

Running this second script performs the actions in your main Magento database.

Remove foreign keys (sales tables)

This script is the removes foreign keys that refer to non-sales tables from the sales database.

select concat(
    'ALTER TABLE ',
    replace(for_name, '<your main magento DB name>/', ''),
    ' DROP FOREIGN KEY ',
    replace(id, '<your main magento DB name>/', ''),
    ';'
    )
from information_schema.INNODB_SYS_FOREIGN
where for_name like  '<your main magento DB name>/|sales_%' escape '|'
    and ref_name not like  '<your main magento DB name>/|sales_%' escape '|'
union all
select concat(
    'ALTER TABLE ',
    replace(for_name, '<your main magento DB name>/', ''),
    ' DROP FOREIGN KEY ',
    replace(id, '<your main magento DB name>/', ''),
    ';'
    )
from information_schema.INNODB_SYS_FOREIGN
where for_name like  '<your main magento DB name>/|magento_sales|_%' escape '|'
    and ref_name not like  '<your main magento DB name>/|sales|_%' escape '|'
;

Remove foreign keys (quote tables)

This script removes foreign keys that refer to non-quote tables from quote tables.

select concat(
    'ALTER TABLE ',
    replace(for_name, '<your main magento DB name>/', ''),
    ' DROP FOREIGN KEY ',
    replace(id, '<your main magento DB name>/', ''),
    ';'
    )
from information_schema.INNODB_SYS_FOREIGN
where for_name like '<your main magento DB name>/%'
    and ref_name like '<your main magento DB name>/sales\_%'
union all
select concat(
    'ALTER TABLE ',
    replace(for_name, '<your main magento DB name>/', ''),
    ' DROP FOREIGN KEY ',
    replace(id, '<your main magento DB name>/', ''),
    ';'
    )
from information_schema.INNODB_SYS_FOREIGN
where for_name like '<your main magento DB name>/%'
    and ref_name like '<your main magento DB name>/magento_sales\_%'
union all
select concat(
    'ALTER TABLE ',
    replace(for_name, '<your main magento DB name>/', ''),
    ' DROP FOREIGN KEY ',
    replace(id, '<your main magento DB name>/', ''),
    ';'
    )
from information_schema.INNODB_SYS_FOREIGN
where for_name like '<your main magento DB name>/%'
    and ref_name like '<your main magento DB name>/magento_customercustomattributes\_%'
;

Drop sales tables

This script drops sales tables from the Magento database.

use <your main magento DB name>;
select ' SET foreign_key_checks = 0;' as querytext
union all
select
    concat('DROP TABLE IF EXISTS ' , table_name, ';')
from information_schema.tables
where table_schema = '<your main magento DB name>'
and table_name like 'sales/_%' escape '/'
union all
select
    concat('DROP TABLE IF EXISTS ' , table_name, ';')
from information_schema.tables
where table_schema = '<your main magento DB name>'
and table_name like 'magento_sales/_%' escape '/'
union all
