Now that we've installed your database, let's connect to it. You can find detailed descriptions for many database connections in this User Manual, however, they all include the same steps:
Ignition connects to databases using JDBC drivers that are unique to each database. Drivers for the most popular databases are included so there is usually no need to install the JDBC driver manually.
Ignition ships with drivers for Microsoft SQL Server, MySQL, Oracle, and PostgreSQL. Pick the JDBC driver for your database, and click on the Next button.Configure the Connection
After selecting the driver, you'll configure the settings for the connection. Some settings, such as the Connect URL are specific to the driver that you're using.
Main Database Connection Properties | |
---|---|
Name | Each database connection needs a unique name, which consists of letters, numbers and underscores. |
Description | A brief description of the database. |
JDBC Driver | The JDBC driver dictates the type of database that this connection can connect to. It cannot be changed once created. |
Connect URL | A string that instructs the driver how to connect to the database. This string is the server address, and may include the port, instance name, database name, and so on. The format and parameters depend on the driver being used. |
Username | The username to use when connecting. Some databases support other authentication methods, such as Windows authentication, in which case this field is not used. |
Change Password? | Check the box to change the existing password. |
Password | Enter password. |
Password | Re-type password for verification. |
Extra Connection Properties | Depending on which database you are connecting to, there will be different default values placed in this box. MS SQL Server requires you to place your database name here, but for other databases you can usually leave this at its default values. Each database has its own set of available extra connection properties so you must refer to your Database documentation to determine what is valid here. |
Enabled | Lets you to enable or disable a database connection. |
Failover Datasource | The connection that is automatically used when this connection is not available. |
Failover Mode | Lets you select how to handle the database connection failing and recovering. Database connections support failover. This means that the objects which use a database connection will use a different connection if the one they are using becomes unavailable. The Failover Datasource property determines which connection is used, and the Failover Mode determines when, if ever, the connection is switch back to the primary connection. There are two failover modes: • STANDARD mode means that this datasource will fail over when a connection cannot be retrieved, but when connectivity is restored, connections will again come from this datasource. • STICKY mode means that once this datasource fails over, connections will continue coming from the failover datasource until the failover datasource itself fails or the Gateway is restarted. |
Slow Query Log Threshold | Queries that take longer than this amount of time, in milliseconds, will be logged. This helps to find queries that are not performing well. (default: 60,000) |
Validation Timeout | The time in milliseconds between database validation checks. (default: 10,000) |
Advanced Settings | |
There are many advanced settings that you don't need to change under normal circumstances. See the description for each property on the settings page. |
