Informatica recommends that you use standard vendor solutions to provide Dynamic Data Masking high availability. For example, you might use failover clustering for Microsoft SQL Server.

To configure Dynamic Data Masking Server high availability for Db2, you can create connection rules that use the Load Control rule action. You must have at least two Dynamic Data Masking Server installations and the database client must use the IBM JDBC driver for Db2. If the Dynamic Data Masking Server installations are on the same machine, they must use different listener ports. After you configure Dynamic Data Masking Server high availability, you can connect to the database through either of the Dynamic Data Masking Servers. If one of the servers is unavailable, the request goes through the other server.
