Preface

Understand the MySQL Adapter

Review the following conceptual topics to learn about the MySQL Adapter and how to use it

as a connection in integrations in Oracle Integration. A typical workflow of adapter and

integration tasks is also provided.

Topics:

• MySQL Adapter Capabilities

• MySQL Adapter Restrictions

• What Application Version Is Supported?

• About MySQL Adapter Use Cases

• Workflow to Create and Add a MySQL Adapter Connection in an Integration

MySQL Adapter Capabilities

The MySQL Adapter enables you to integrate the MySQL database residing behind the

firewall of your on-premises environment with Oracle Integration through use of the on-

premises connectivity agent. Use the MySQL Adapter to poll for new and updated records for

processing in Oracle Integration. For example, any new record added to the

Employee

table in

your MySQL database can be synchronized with Oracle HCM Cloud using Oracle Integration.

In addition, use the MySQL Adapter to execute SQL queries or stored procedures in the

MySQL database. For example, quotes in Oracle CPQ Cloud can be created as

Orders

in the

on-premises MySQL database by sending SQL statements or stored procedures using the

MySQL Adapter.

The MySQL Adapter provides the following capabilities:

• Support for invocation of stored procedures in the MySQL database.

• Support for execution of DML statements and SQL queries:

Select

Insert

Update

, and

Delete

Select the Run a SQL Statement option on the Basic Info page of the Adapter Endpoint

Configuration Wizard to execute simple SQL queries. For complex SQL queries, use

stored procedures by selecting the Invoke a Stored Procedure option on the Basic Info

page of the Adapter Endpoint Configuration Wizard. Stored procedures can reduce the

complexity of a SQL query.

• Support for generating XSD from PureSQL. This feature generates an XSD from a

PureSQL statement provided by dynamically querying on the table.

• Support for polling new and updated records for processing in the MySQL database. The

MySQL Adapter supports distributed polling. Distributed polling helps eliminate duplicate

polling of the same records.

• Support for performing a

SELECT

operation against database tables.

• Support for bulk data import and extract by choosing the SELECT operation from the

Perform an Operation On a Table list on the Basic Info page.

1-1

• Support for a logical delete polling strategy. This strategy involves updating a

special field on each row once it is processed.

• Support for processing message payloads up to 10 MB in size. In the case of

polling, you must set the Rejected Value property to REJECTED on the Polling

Strategy and Options page. If the incoming message is greater than the 10 MB

threshold size, that particular record is updated to REJECTED instead of READ. If

the outbound operation returns a response greater than the 10 MB threshold size,

the response message is ignored and a fault response is sent to the calling client.

Note:

In Java, Unicode characters are represented as 2 bytes.

The MySQL Adapter is one of many predefined adapters included with Oracle

Integration. You can configure the MySQL Adapter as an invoke connection in an

integration in Oracle Integration.

Supported Data Types for SQL Stored Procedures

The MySQL Adapter supports the following data types for SQL stored procedures.

MySQL Adapter Restrictions

Note the following MySQL Adapter restrictions.

• The MySQL Adapter can only be used with the on-premises connectivity agent.

• The database password length cannot exceed 20 characters.

• Database schema names with hyphens (

) are not supported.

• The MySQL Adapter supports processing message payloads up to 10 MB in size. In the

case of polling, you must set the Rejected Value property to REJECTED on the Polling

Strategy and Options page. If the incoming message is greater then the 10 MB threshold

size, that particular record is updated to REJECTED instead of READ. If the outbound

operation returns a response greater than the 10 MB threshold size, the response

message is ignored and a fault response is sent to the calling client.

• All integrations that include stored procedure, PureSQL, or operation on table database

operations must finish within 240 seconds. Otherwise, the query times out and a

Limit

Exceeded

error occurs.

Note:

There are overall service limits for Oracle Integration. A service limit is the quota or

allowance set on a resource. See Service Limits.

What Application Version Is Supported?

For information about which application version is supported by this adapter, see the

Connectivity Certification Matrix.

See Connectivity Certification Matrix.

About MySQL Adapter Use Cases

The MySQL Adapter can be used in scenarios such as the following:

Chapter 1

MySQL Adapter Restrictions

1-3

You can create an integration that includes a SOAP Adapter connection on the trigger

(inbound) side and a MySQL Adapter on the invoke (outbound) side. For example,

when configuring the invoke MySQL Adapter, you can select a stored procedure that

enables you to pass an employee ID as an inbound parameter from the SOAP Adapter

to an on-premises MySQL database to retrieve additional information about the

employee (first name, last name, email ID, and so on).

Workflow to Create and Add a MySQL Adapter Connection

in an Integration

You follow a very simple workflow to create a connection with an adapter and include

the connection in an integration in Oracle Integration.

Step Description More Information

1 Create the adapter connections

for the applications you want to

integrate. The connections can

be reused in multiple

integrations and are typically

created by the administrator.

Workflow to Create and Add a MySQL Adapter Connection in an Integration

1-4

Create a MySQL Adapter Connection

A connection is based on an adapter. You define connections to the specific cloud

applications that you want to integrate.

Topics:

• Prerequisites for Creating a Connection

• Create a Connection

Prerequisites for Creating a Connection

You must satisfy the following prerequisites to create a connection with the MySQL Adapter:

• Ensure that you have write permissions on the database.

• Ensure that you have the required permissions to run stored procedures and packages

and SQL statements against the MySQL Database.

• Know the database hostname or IP address and the port number.

• Know the database name.

• Know the username and password for connecting to the database.

• Download the

mysql-connector-java-commercial-5.1.22-bin.jar

or the relevant

mysql-connector

JAR based on your MySQL database version to the host on which the

connectivity agent is installed.

For example, perform the following steps if

mysql-connector-java-commercial-5.1.22-

bin.jar

is the JAR required for your environment.

1. Download the

mysql-connector-java-commercial-5.1.22-bin.jar

from the MySQL

Database site. Check the Oracle Integration Adapters Certification matrix to identify

the certified versions of the MySQL Database.

2. Copy the JAR file to

agenthome/thirdparty/lib

3. Restart the connectivity agent.

If you do not download and install this JAR file, you receive a

Check agent status

error when testing the connection on the Connections page in Oracle Integration.

Create a Connection

Before you can build an integration, you have to create the connections to the applications

with which you want to share data.

To create a connection in Oracle Integration:

1. In the left navigation pane, click Home > Integrations > Connections.

2. Click Create.

2-1

Note:

You can also create a connection in the integration canvas of:

• An orchestrated integration (See Define Inbound Triggers and

Outbound Invokes.)

• A basic routing integration (See Add a Trigger (Source) Connection.)

3. In the Create Connection — Select Adapter dialog, select the adapter to use for

this connection. To find the adapter, scroll through the list, or enter a partial or full

name in the Search field and click

Search.

4. In the Create Connection dialog, enter the information that describes this

connection.

a. Enter a meaningful name to help others find your connection when they begin

to create their own integrations. The name you enter is automatically added in

capital letters to the Identifier field. If you modify the identifier name, don't

include blank spaces (for example,

SALES OPPORTUNITY

b. Enter optional keywords (tags). You can search on the connection keywords

on the Connections page.

c. Select the role (direction) in which to use this connection (trigger, invoke, or

both). Only the roles supported by the adapter are displayed for selection.

When you select a role, only the connection properties and security policies

appropriate to that role are displayed on the Connections page. If you select

an adapter that supports both invoke and trigger, but select only one of those

roles, you'll get an error when you try to drag the adapter into the section you

didn't select. For example, let's say you configure a connection for the Oracle

Service Cloud (RightNow) Adapter as only an invoke. Dragging the adapter to

a trigger section in the integration produces an error.

d. Enter an optional description of the connection.

5. Click Create.

Your connection is created. You're now ready to configure the connection details,

such as connection properties, security policies, connection login credentials, and

(for certain connections) agent group.

Configure Connection Properties

Enter connection information so your application can process requests.

1. Go to the Connection Properties section.

2. Enter the host name or IP address of the database server.

3. Enter the database server port number.

4. Enter the database name.

By default, the MySQL client establishes secure connections with the SSL-enabled

MySQL servers. There is currently no support for SSL-encrypted network

connections in the MySQL Adapter. As a workaround, you can use a new or

Chapter 2

Create a Connection

2-2

additional parameter in the Database Name field to connect with SSL-enabled MySQL

servers.

MySQL Version Recommended Parameter

8.0.12 and earlier

useSSL=false

For example,

test?useSSL=false

, where:

•

test

is the database name

•

is a required character

•

useSSL=false

is the parameter setting

8.0.13 and later

sslMode=DISABLED

For example,

test?sslMode=DISABLED

where:

•

test

is the database name

•

is a required character

•

sslMode=DISABLED

is the parameter

setting

Configure Connection Security

Configure security for your MySQL Adapter connection by selecting the security policy and

security token.

1. Go to the Security section.

The Security Policy field displays Username Password Token. This value cannot be

changed.

2. Complete the Username, Password, and Confirm Password fields.

Configure an Agent Group

Configure an agent group for accessing the service hosted on your premises behind the fire

wall.

1. Click Configure Agents.

The Select an Agent Group page appears.

2. Click the name of the agent group.

3. Click Use.

To configure an agent group, you must download and install the on-premises connectivity

agent. See Download and Run the Connectivity Agent Installer and About Connectivity

Agents and Integrations Between On-Premises Applications and Oracle Integration in Using

Integrations in Oracle Integration Generation 2.

Test the Connection

Test your connection to ensure that it's configured successfully.

1. In the page title bar, click Test. What happens next depends on whether your adapter

connection uses a Web Services Description Language (WSDL) file. Only some adapter

connections use WSDLs.

Chapter 2

Create a Connection

2-3

If Your

Connection...

Then...

Doesn't use a WSDL The test starts automatically and validates the inputs you provided

for the connection.

Uses a WSDL A dialog prompts you to select the type of connection testing to

perform:

• Validate and Test: Performs a full validation of the WSDL,

including processing of the imported schemas and WSDLs.

Complete validation can take several minutes depending on

the number of imported schemas and WSDLs. No requests are

sent to the operations exposed in the WSDL.

• Test: Connects to the WSDL URL and performs a syntax

check on the WSDL. No requests are sent to the operations

exposed in the WSDL.

2. Wait for a message about the results of the connection test.

• If the test was successful, then the connection is configured properly.

• If the test failed, then edit the configuration details you entered. Check for

typos, verify URLs and credentials, and download the diagnostic logs for

additional details. Continue to test until the connection is successful.

3. When complete, click Save.

Add the MySQL Adapter Connection to an

Integration

When you drag the MySQL Adapter into the trigger or invoke area of an integration, the

Adapter Endpoint Configuration Wizard appears. This wizard guides you through the

configuration of the MySQL Adapter endpoint properties.

These topics describe the wizard pages that guide you through configuration of the MySQL

Adapter as a trigger or invoke in an integration.

Topics:

• Basic Information Page

• Invoke a Stored Procedure Properties

• Invoke SQL Statement Properties

• Trigger Polling Properties

• Summary Page

Basic Information Page

You can enter a name and description on the Basic Info page of each trigger and invoke

adapter in your integration.

Element Description

What do you want to call your

endpoint?

Provide a meaningful name so that others can understand

the connection. For example, if you are creating a database

connection for adding new employee data, you may want to

name it

CreateEmployeeInDB

. You can include English

alphabetic characters, numbers, underscores, and dashes in

the name. You cannot include the following:

• Blank spaces (for example,

My DB Connection

)

• Special characters (for example,

#;83&

righ(t)now4

)

• Multibyte characters

3-1

Element Description

What operation do you want to

perform?

Select the type of operation for this connection to perform:

•

Invoke a Stored Procedure: Select to invoke a stored

procedure in the database.

•

Run a SQL Statement: Select to run a SQL query

against the database.

•

Perform an Operation On a Table — Select to perform

one of the following operations on a table. You can

update or insert multiple records in a single request.

– Insert

– Update

– Insert or Update (Merge)

–

Select

Note: When operations in a SQL statement such as Update,

Concat, and Merge accept values for the inbound invocation

of an integration, they do not work. For example, the

following query does not work:

select concat(empname, 'ss') from DB_AQ

where empno=#empno

select empno from DB_AQ where

empname=concat(#empname, 'YY')

As a workaround, handle these scenarios during payload

mapping. For example, perform a concatenation during

mapping of the payload. The final output can then be passed

as input to the SQL query.

Invoke a Stored Procedure Properties

Enter the MySQL Adapter invoke stored procedure parameters. The Invoke a Stored

Procedure page is the wizard page that is displayed if you selected Invoke a Stored

Procedure as the operation type on the Basic Info page.

Note:

• Stored procedures return binary large objects (for example, BLOB

database data types) as base64Binary types in XML. Depending upon

the use cases, these can be decoded during transformation using inbuilt

functions such as decodeBase64 or can be passed as-is for downstream

processing.

• Adapter input/output parameters are defined based on the stored

procedure IN/OUT parameters. The IN parameter corresponds to the

request and the OUT parameter is translated as the response.

Chapter 3

Invoke a Stored Procedure Properties

Element Description

Select Schema

Select a database schema from the list that includes the data

you want to query (for example, you want to query details

about an employee based on their employee ID). This action

refreshes the page to display fields for selecting a package

or procedure to invoke.

Select Package

Select the database package.

Select Procedure

Select the stored procedure. The page is refreshed to display

the in (inbound), out (outbound), and in/out (inbound/

outbound) parameters available with this procedure.

Arguments

Display the in, out, and in/out parameters that are passed

with this procedure.

Invoke SQL Statement Properties

Enter the SQL statement parameters. The Create a SQL Statement page is the wizard page

that is displayed if you selected Run a SQL Statement as the operation type on the Basic Info

page.

Note:

• Do not use schema/database names in SQL queries. Configure the details in

the connection. For example:

Update HR.employee set HR.employee.first_name = 'Name' where

HR.employee.employee_id='1'

can be changed to a simple query, such as:

Update employee set first_name = 'Name' where employee_id='1'

where

is used in the connection details. This restricts a user with specific

privileges to a particular schema/database.

• When configuring the adapter as an invoke connection, ensure that proper

spaces are provided between key words for a pure SQL statement. For

example, the following statement fails during integration activation because

there is no blank space between

VALUES

and

INSERT INTO table_name VALUES(#EMPNO, #EMPNAME)

Add a blank space between VALUES and (#, and the statement is successfully

processed.

INSERT INTO table_name VALUES (#EMPNO, #EMPNAME)

Implement Common Patterns Using the

MySQL Adapter

You can use the MySQL Adapter to implement common patterns.

Topics:

• Define a Select Operation on Database Tables

Define a Select Operation on Database Tables

You can define a

SELECT

operation to perform against database tables. This section provides

a high level overview of creating an integration in which a MySQL Adapter is configured as an

invoke connection to retrieve table records from the MySQL.

To define a

SELECT

operation on database tables:

1. Configure SOAP Adapter and MySQL Adapter connections.

2. Select App driven orchestration in the Create integration dialog.

3. Add and configure the SOAP Adapter as a trigger connection in the integration.

The SOAP Adapter is configured to accept an input and return the response received

from the invoke connection.

4. Add the MySQL Adapter as an invoke connection in the integration.

This invokes the Adapter Endpoint Configuration Wizard.

5. On the Basic Info page, select Perform an Operation On a Table as the type of

operation to perform and Select as the operation to perform on the table.

6. On the Operation On Table page, specify the schema and tables to import, and click

Import Tables. For this example, the following values are specified.

• Schema: HR

• Table Type: TABLE

• Table Name:

%TAB

• Selected Tables: EMPLOYEE_TAB and DEPARTMENT_TAB. The tables are

imported together for the MySQL Adapter to recognize the relation between the

tables.

4-1

The page is refreshed for you to select the parent (root) database table.

7. Select the parent table (for this example, DEPARTMENT_TAB is selected).

This page enables you to:

• View the automatically created table relationships and create new ones.

• View and deselect attributes.

• View and edit the automatically created SQL query.

Troubleshoot the MySQL Adapter

Review the following topics to learn about troubleshooting issues with the MySQL Adapter.

Topics:

• Troubleshoot a Connection Test Error

Additional integration troubleshooting information is provided. See Troubleshoot Oracle

Integration in Using Integrations in Oracle Integration Generation 2 and the Oracle Integration

Troubleshooting page on the Oracle Help Center.

Troubleshoot a Connection Test Error

You can receive the following error when testing the MySQL Adapter connection on the

Connections page.

If you receive this error, ensure that you perform the following prerequisite steps:

1. Download the

mysql-connector-java-commercial-5.1.22-bin.jar

driver file from the

MySQL Database site.

2. Copy the driver file to the

agenthome/thirdparty/lib

directory of the instance on which

the connectivity agent is installed.

3. Restart the connectivity agent.
