MySQL is the #1 open source database. Oracle Cloud is a complete, integrated cloud and provides a wide range of services across Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Oracle PaaS provides Oracle Database and MySQL Database services in the Oracle Cloud. Oracle MySQL Cloud Service is a simple, automated, managed service that is enterprise ready. Oracle MySQL Cloud Service is a scalable, highly available, and secure service that provides all the features and management tools that a DBA would need for database administration. Common DBA tasks such provisioning, patching, backup and recovery, performance monitoring, scaling, replication, and authentication are managed by the MySQL Cloud service. Oracle MySQL Cloud service is seamlessly integrated with other Oracle Cloud services such as Java Cloud Service, Mobile Cloud, Messaging Cloud, Application Container Cloud, and Developer Cloud.
Oracle MySQL Cloud Service relies on standard MySQL server tools to load data into the cloud service. A user interface to access the Oracle MySQL Cloud Service and perform data management tasks would be useful management tool.
Toad Edge is an all-in-one data management toolset for MySQL database (support for other open source databases to be added). Toad Edge Preview software is available for download here.
From the Toad Edge graphical user interface (GUI) connect to a MySQL database service in the Oracle MySQL Cloud and create database objects including tables and load data into the tables, or run SQL scripts in a SQL Worksheet to add table data. Table data may be exported to SQL scripts or spreadsheets. Other typical DBA tasks, such as creating users and setting user privileges, may also be performed from Toad Edge.
In this article we shall discuss using Oracle MySQL Cloud Service with Toad Edge Preview. This article has the following sections.
To use Oracle MySQL Cloud Service create an Oracle Cloud account at https://cloud.oracle.com/ . If exploring and evaluating Oracle Cloud, use the free trial at https://cloud.oracle.com/tryit to get started. After registering a user account with Oracle Cloud a user is sent the following information which is unique to the user:
A My Services URL is also included in the email message sent on the activation of an Oracle Cloud user account. To log in to the Oracle Cloud services open the My Services URL in a browser and provide the username, password and identity domain.
The Oracle Cloud provides several services; the service that includes MySQL database is the Oracle Database Cloud service. Oracle Database service is available in various subscription formats: Metered Services, Virtual Image, Non-Metered Services, and Non-Metered Virtual Image. Detailed information about the various Oracle Cloud services is available on the free trial page at https://cloud.oracle.com/tryit.
Download and install Toad Edge Preview from http://www.toadworld.com/products/toad-edge/. Supported OS are Windows and Mac OS X.
Select the Oracle MySQL Cloud Service in the Oracle Cloud My Services. Click on Create Service as shown in Figure 1.
Figure 1. Create Service
Specify a Service Name (mysqldb), select a Datacenter Region, and select a Metering Frequency as shown in Figure 2. Region may be selected as “No Preference” if a specific region is not to be provided. Click on Next.

In this section we shall connect to the MySQL Database instance running in Oracle MySQL Cloud from Toad Edge. But first, we need to obtain the connection detail for the MySQL Cloud service. In the Service Overview, which may be displayed from the mysql service link, copy the Connect Descriptor as shown in Figure 14.
Figure 14. Obtaining the Connect Descriptor
In the Toad Edge click on Connect>New Connection as shown in Figure 15.
Figure 15. Connect>New Connection
In the New MySQL Connection specify the Public IP from the Connect Descriptor in the Host field. Specify the port 3306 in the Port field and specify the database instance (schema) name mysqldb in the Database field as shown in Figure 16. In Authentication specify User as root and Password as the password configured when creating the MySQL Cloud service. In Options, Enable AutoCommit and Restore previous work after login are enabled by default and should be kept as such. The Connection Name, which is generated automatically, must be unique. The Connection String Preview lists the connection URL for the MySQL Cloud service database. Click on Test Connection to test the connection. If the connection gets established, a message "Connection is OK" gets displayed, as shown in Figure 16.
Figure 16. Configuring and Testing Connection
Click on OK as shown in Figure 17.
Figure 17. Applying the Connection Configuration
A connection to the Oracle MySQL Cloud database gets created in Toad Edge and gets added in Connections, as shown in Figure 18.
Figure 18. Connection to MySQL Cloud Service Database Created in Toad Edge
The active database is the mysqldb database, which is configured when creating the MySQL Cloud service, as shown in Object Explorer in Figure 19.
Figure 19. Active Database mysqldb
The Users are also listed in the Object Explorer, as shown in Figure 20.
Figure 20. Users
When configuring the connection, the error “Connection has failed. Communications link failure” could get generated, as shown in Figure 21, even though all the connection parameters are configured as required. The error message is due to the network public access not being enabled to the MySQL Cloud service. Enabling public access is discussed in the previous section.
Figure 21. Connection has failed. Communications link failure
After creating a connection to Oracle MYSQL Cloud service in Toad Edge, a database table may be created using a SQL Worksheet. One Worksheet is added by default when a new connection is created. Copy the following CREATE TABLE statement to the SQL Worksheet.
CREATE TABLE wlslog(time_stamp VARCHAR(255) PRIMARY KEY,category VARCHAR(255),type VARCHAR(255),
servername VARCHAR(255), code VARCHAR(255),msg VARCHAR(255));
Click on Execute SQL Statement as shown in Figure 22.
