Database Connection Pools
Database connections allow database servers and software to interact with each other in an efficient manner. Of course, this statement still holds true in TORO Integrate's environment.
Using registered database connection pools, services will be able communicate with your databases and perform operations against them. You're also free to remove and update existing pools, as well as enable or disable them.

TORO Integrate uses JDBC drivers to connect to certain databases. The table below describes which drivers are available in Java and should be compatible with TORO Integrate:
|Driver||Name||Built-in Driver||XA Support|
||Microsoft SQL Server (JTurbo Driver)||No||Emulated|
||IBM DB2 (jcc4)||No||Natively|
||Microsoft SQL Server (Sprinta Driver)||No||Emulated|
||Informix Dynamic Server||No||Natively|
||Microsoft SQL Server||Yes||Natively|
||PointBase Embedded Server||No||Emulated|
||Sybase (jConnect 4.2 and earlier)||No||Emulated|
||Sybase (jConnect 5.2)||No||Emulated|
||Hypersonic SQL (v1.2 and earlier)||No||Emulated|
||InstantDB (v3.13 and earlier)||No||Emulated|
||jTDS (Sybase), jTDS (SQL Server)||Yes||Natively|
||Oracle OCI 8, Oracle OCI 9+, Oracle Thin||No||Natively|
||InstantDB (v3.14 and later)||No||Natively|
||MySQL (mm.MySQL Driver)||No||Emulated|
||Hypersonic SQL (v1.3 and later)||No||Emulated|
||Hypersonic SQL (v2.0+ Remote), Hypersonic SQL (v2.0+ File)||Yes||Natively|
||PostgreSQL (v7.0 and later)||Yes||Natively on PostgreSQL 8 only|
||PostgreSQL (v6.5 and earlier)||No||Emulated|
In addition to the drivers above, TORO Integrate also supports the installation of other database drivers. For more
information, please read about maintaining database connection pools. To use XA
transactions, the JDBC driver must implement
Check your license!
The availability of database drivers will depend on the type of license you jave installed.
The properties below are used to described database connections. TORO Integrate, which uses Bitronix underneath, will use these configuration fields when connecting to the target database. You can learn more about these properties in Bitronix's JDBC Configuration Pools page.

A database connection's status indicates the current state of the database connection. It is manually set by starting or stopping a database connection. Certain actions would only be available on certain states; for example, you may configure the properties of a database connection only if it stopped.
The following are the different possible connection statuses:
Indicates that there is an established connection between TORO Integrate and the database. Connectivity is required if any of your integrations need to use the database. A database connection with this status is shown with a green visual indicator in the UI.
Indicates that there is no established connection between TORO Integrate and the database. A database connection with this status is shown with a red visual indicator in the UI.
As Seen in Coder
To view the existing database connection pools of your instance, open the Coder Navigator view, navigate to your instance's entry, and under your entry, expand the Databases section.
To perform an action on a database connection pool, right click its entry and select from the list of actions in the context menu that will appear. Depending on the state of your pool, some actions may or may not be executable.
