The only prerequisite is an IBM Bluemix account, which may be created at


Creating a MySQL Database on Bluemix

Bluemix offers ClearDB Managed MySQL Database. Login into Bluemix and select the ClearDB Managed MySQL Database service in the Data & Analytics category of the Catalog as shown in Figure 1.

Figure 1. Selecting ClearDB Managed MySQL Database

Specify a Service name (or select the default name), select the Free edition of ClearDB Managed MySQL Database to start with, and click on Create as shown in Figure 2.

Figure 2. Selecting the Free Edition of ClearDB Managed MySQL Database

The managed MySQL database service gets launched.  Click on the button to open the managed service Dashboard as shown in Figure 3.

Figure 3. Opening ClearDB MySQL Dashboard

The ClearDB dashboard gets displayed with a list of databases, as shown in Figure 4. Click on the database link to display database cluster details.

Figure 4. ClearDB Dashboard

The cluster details for the database get displayed. Select the Endpoint Information tab to display the Cluster Gateway Hostname and Cluster Nodes as shown in Figure 5. The Access Credentials, consisting of a Username and Password, are also displayed. When connecting to ClearDB MySQL we shall use the Hostname and the access credentials.

Figure 5. Cluster Details

Multiple database services for ClearDB may be created, as shown in Figure 6.


Figure 6. Multiple Databases

The SSL Certificates required to connect to the managed service for MySQL database on Bluemix using SSL are also listed on the Dashboard, as shown in Figure 7.

Figure 7. SSL Certificates


Creating a Connection to MySQL on Bluemix

To connect to MySQL database from Toad Edge copy the following connection parameters.

Username:    b677c0c7fa3704
Password:    bd7441a4 

The preceding information is obtained from the Dashboard, as shown in Figure 5. To create a connection to MySQL from Toad Edge select Connect>New Connection as shown in Figure 8.

Figure 8. Connect>New Connection

In the New MySQL Connection wizard specify Host as the Hostname ( of the database on Bluemix.  Port is set to 3306. Enable AutoCommit option should be selected. Specify User and Password as the access credentials for the MySQL database on Bluemix. Click on Test Connection and if the “Connection is OK” message gets displayed click on OK, as shown in Figure 9.

Figure 9. Configuring a Connection in Toad Edge

A connection for the MySQL database gets created and added to the Connections navigator, as shown in Figure 10. A message indicates that an “Active database is not defined”. An active database is the database currently being used, and we shall select an active database next.

Figure 10. Connection to MySQL Database Added

Multiple database connections may be added and used in Toad Edge simultaneously, as indicated by the two connections listed in Connections in Figure 11.

Figure 11. Multiple Connections


Setting the Active Database

To set the active database we need to open the Object Explorer. Open the Object Explorer by selecting View>Object Explorer as shown in Figure 12.

Figure 12. View>Object Explorer

The Databases for the ClearDB connection get listed in the Object Explorer. Right-click on the Databases node and select Refresh to refresh the databases, as shown in Figure 13.

Figure 13. Refreshing Databases

Right-click on the database to be made the active database and select Set Active Database as shown in Figure 14.


Figure 14. Setting Active Database

The selected database becomes the active database, as shown in Figure 15. Only one database may be made active at a time.

Creating an SSL Connection to MySQL on Bluemix

SSL (Secure Sockets Layer) is a data security technology for establishing an encrypted connection between a web server and a client browser.  All data exchanged through an SSL connection is secure and  reliable. SSL encryption in ClearDB makes use of three certificates.

  • ClearDB CA (Certificate Authority) Certificate (cleardb-ca.pem file)
  • Client SSL Certificate (-cert.pem suffix  file)
  • Client SSL Private Key  (-key.pem suffix file)

Download the SSL certificate files from the ClearDB Dashboard on Bluemix as shown in Figure 16.

Figure 16. Downloading SSL Certificates from ClearDB Dashboard in Bluemix

The private key (a41165380258c5-key.pem) is associated with a password  or passphrase. Generate an RSA (no password) version of the private key with the following command in a command shell.

openssl rsa -in a41165380258c5-key.pem -text -out a41165380258c5-key.pem

To create an SSL connection, select Connect>New Connection as before (Figure 8) and in New MySQL Connection specify the same Host, Port, User and Password. Click on the SSL tab to enable SSL as shown in Figure 17.

Figure 17. Selecting SSL Tab

Click in the Enable SSL checkbox. Upload the SSL CA File, SSL Cert File, and SSL Key File, as shown in Figure 18. Click on Test Connection to test the SSL connection and the message Connection is OK indicates that the SSL connection gets established. Click on OK.


Figure 18. Testing SSL Connection

A SSL connection gets added, as shown in Figure 19. The connection name is the same as the non-SSL connection except for ‘ssl’ included in the connection name.


Figure 19. SSL Connection added

The active database needs to be set for an SSL connection; for which, right-click on a database and select Set Active Database, as shown in Figure 20.

Figure 20. Setting Active Database

The active database for the SSL connection gets set, as shown in Figure 21.

Creating and Querying a MySQL Table using SSL Connection

Open a SQL Worksheet associated with the database connection to ClearDB MySQL and copy the following SQL statement to the worksheet.

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:16-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STANDBY');

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:17-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STARTING');

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:18-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to ADMIN');

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:19-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RESUMING');

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:20-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000361','Started WebLogic AdminServer');

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:21-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RUNNING');

INSERT INTO weblogiclog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:22-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000360','Server started in RUNNING mode');

The SQL Worksheet with the preceding SQL script is shown in Figure 22.

Figure 22. SQL Worksheet with SQL Script

Click on Execute All Statements as shown in Figure 23.

Figure 23. Execute All Statements

The SQL statements get processed, as indicated by the message in Figure 24. Database table weblogiclog gets created.

Disconnecting and Removing a MySQL Connection

A connection that is connected is distinguished from a connection that is not connected by a red marker in the disconnected connection.  The non-SSL connection in Figure 26 is disconnected, and the SSL connection is connected. To disconnect a SSL connection right-click on the connection and select Disconnect as shown in Figure 26.

Figure 26. Disconnect

The SSL connection gets disconnected and a red marker gets added to the connection node in Connections, as shown in Figure 27.

Figure 27. SSL Connection Disconnected

The SSL connection may be connected again by selecting Connect.  To remove the SSL connection right-click on the connection node and select Remove Connection as shown in Figure 28.

Figure 28. Remove Connection

Click on OK in the Confirm dialog as shown in Figure 29.
