MySQL SSL Warning in server log

WARN: Establishing SSL connection without server’s identity verification is not recommended.
According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set.
For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’.
You need either to explicitly disable SSL by setting useSSL=false on the JDBC URL String
or set useSSL=true and provide truststore for server certificate verification.

How do I configure BridgeGate with mysql database failover

BridgeGate can be configured for mysql database failover with the following updates to the jdbc url in the bridgegate.xml

MySQL jdbc supports server failover. A failover happens when connection-related errors occur for an underlying, active connection.  ie Database down.  A connection using failover support works just like a standard connection: the client does not experience any disruptions in the failover process.

Update the jdbc url to include the primary database IP and then a comma list of secondary IP address.

jdbc:mysql://, …..

Below is an example of the bridgegate.xml configured with a primary db on IP  and the secondary db on IP 192.168.18

<DATABASE_CONNECTION_POOL ACQUIRE_INCREMENT=”2″ AUTO_COMMIT_ON_CLOSE=”false” CHECKOUTTIME=”600″ DRIVER=”com.mysql.cj.jdbc.Driver” IDLETIME=”600″ IDLE_TEST_PERIOD=”300″ JDBCURL=”jdbc:mysql://,;autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8&amp;zeroDateTimeBehavior=convertToNull” MAXCONN=”300″ MAX_STATEMENTS=”0″ MINCONN=”10″ PASSWORD=”ENC3AMq%2BPLK4Q%2Bzvhu2oJhQvw%3D%3D” USERNAME=”bridgegate”/>

MySQL also supports load balancing across DBs.

Update bridgegate.xml to use the mysql loadbalance feature. Append loadBalanceStrategy=bestResponseTime to the existing URL. For

More details can be found on the mysql site.  See below

Where is the location for SQL statements that failed to commit?

While BridgeGate is logging transaction/workflow details to the database, if it experiences issues saving a SQL statement to the database the statements are saved in the following location and will be automatically retried every 20 minutes.



How do I connect to a SQL Server database

There are many connection options for SQL Server.  The quickest way is to configure a Predefined Connection using JDBC. BridgeGate includes a generic JDBC driver for SQL Server named jtds.

The JDBC Syntax

The general form of the connection URL is



  • jdbc:jtds:sqlserver:// (Required) is known as the sub-protocol and is constant.
  • serverName (Optional) is the address of the server to connect to. This could be a DNS or IP address, or it could be localhost or for the local computer. If not specified in the connection URL, the server name must be specified in the properties collection.
  • instanceName (Optional) is the instance to connect to on serverName. If not specified, a connection to the default instance is made.
  • portNumber (Optional) is the port to connect to on serverName. The default is 1433. If you are using the default, you do not have to specify the port, nor its preceding ‘:’, in the URL.

Examples of connecting to a SQLServer database with the instance name of MSSQLSERVER and the database schema name of BillingTest1

You can find the instance name in the SQL Management or by looking at the Services Name

You can find the databasename in the SQL Management under Databases.


Once you have located the two parameters you can build the JDBC String on the Predefined Connection screen in BridgeGate.

In this example the full syntax is


How do I manually backup the bridgegate database

Backup MySql Database using MySqlAdmin or mysqldump (Instructions below)

  • Open a Command prompt on the desktop of the BridgeGate server.
  • Assuming BridgeGate 7.0 is installed on c:
  • At a c:\bridgegate\mysql\bin> prompt
  • Replace MYSQLPASSWORD in the below command with your current MySql password
  • Run: ” mysqldump -u bridgegate -pMYSQLPASSWORD –routines –hex-blob bridgegate > c:\bridgegate\bg.sql”
    • If you have MySQL databases other than bridgegate, you can backup all of them together with the following:
      • Run: “mysqldump -u bridgegate -pMYSQLPASSWORD –routines –hex-blob –databases bridgegate db1 db2 db3 db4 > c:\bridgegate\bg.sql”
      • Replace db1 db2 db3 db4 with the other database names

Can BridgeGate access DB2 tables on an AS400

Yes as long as you can access the DB via JDBC or ODBC

How do I backup my MySQL Database manually

When backing up databases manually you should use the —hex-blob option  to ensure encrypted data is not corrupted.   We have seen issues in the past where an ascii dump has issues.

  • Open a Command prompt on the desktop of the BridgeGate server.
  • Assuming BridgeGate is installed on E:
  • At a E:\bridgegate\mysql\bin> prompt
  • Replace MYSQLPASSWORD in the below command with your current MySql password
  • Run: “mysqldump -u bridgegate -p –add-drop-database –hex-blob –routines bridgegate > E:\bg_backup\bridgegate\bg.sql”
    • If you have MySQL databases other than bridgegate, you can back up all of them together with the following:
      1. Run: “mysqldump -u bridgegate -p –routines –add-drop-database –databases bridgegate db1 db2 db3 db4 > E:\bg_backup\bridgegate\bg.sql”
        • Example: “mysqldump -u bridgegate -p –routines –add-drop-database –databases bridgegate ccd cda mds mpi msg_tracking nemsis oasis > E:\bg_backup\bridgegate\bg.sql”
