Managing Extended Connectors¶
Extended Connectors allow you to upload additional JDBC Drivers to the Delphix Masking Engine to enable masking of data sources not natively supported by Delphix Masking.
Delphix supports type 4 JDBC Drivers. These must be a pure-java .jar file that can be used simply by uploading it (or it’s zip file) to the engine. Anything that requires compilation on the engine, or execution of any kind of install or licensing script, is not supported.
Extended Connectors don't support all of the features available for built-in connectors like Oracle. The "Disable Constraint", "Disable Trigger" and "Drop Indexes" options are not available on jobs using extended connectors. Delphix provides support for Extended Connectors in accordance with our Support Policy
Drivers that require a Java version higher than 8 are not supported.
Installing a new driver¶
To use a new JDBC driver, first you need to upload it to your Masking Engine. Since some drivers require multiple files, the driver and any additional files it needs to function should be put together in a single zip file. Even if a driver doesn't require additional files, it still needs to be zipped.
For example, to package the Informix JDBC driver for use with Delphix Masking take all three files provided for Informix and zip them together:
$ ls LICENSE.txt ifxjdbc.jar ifxlang.jar $ zip informix.zip * adding: LICENSE.txt (deflated 70%) adding: ifxjdbc.jar (deflated 4%) adding: ifxlang.jar (deflated 4%) $ ls LICENSE.txt ifxjdbc.jar ifxlang.jar informix.zip $
To upload the driver package to the engine, navigate to the JDBC Drivers under Settings
Clicking Add Driver will bring up a dialog box to upload the driver zip file and enter the driver's configuration details.
The Add Driver screen lets you set the following information.
- Name A human-readable name for the driver. Name it whatever is convenient for you. Note: Special Characters are not allowed in the Name field.
- Description A human-readable description of the driver.
- Class Name The Fully Qualified Class Name of the class in the JDBC driver that implements the java.sql.Driver interface. The class name will be in the documentation for the driver itself.
- Select JDBC driver for upload Lets you select the zip file containing the driver and upload it.
- Permissions Additional permissions required by the driver. See the Driver Permissions section
To remove an uploaded driver, click the Delete button to the right of the connector on the JDBC Drivers tab. Note that the delete will fail if any Connectors exist that use the driver you're trying to delete.
If you find you need to edit a driver's configuration options later, click the pencil icon next to the driver's listing on the JDBC Drivers tab.
The Delphix Masking Engine uses the Java Security Manager to prevent uploaded JDBC drivers from performing certain actions without your permission.
Uploaded drivers are granted all permissions except for the following non-
|java.net.SocketPermission||localhost:-||accept, connect, listen, resolve|
With regards to FilePermissions,
read access is granted to all, though
write is only allowed for the following
- the masking user's home directory (
- the JVM's default temp directory (
Please note that both of these locations are shared, so care will need to be taken to avoid collisions.
The set of permissions granted to uploaded drivers is static and cannot be modified.
The Delphix Masking Engine provides enhanced logging for extended connectors to assist in debugging connection problems. Enhanced logging can be enabled when the connector is created by checking the 'Enable Logger' box. Enhanced logging may have an impact on performance so you should enable it only when debugging connection problems.
Note that extended logging will not work with signed drivers such as MSSQL.
Enhanced Logging requires some additional permissions to be granted.
|Class Name||Target Name||Action Name||Purpose|
|java.io.RuntimePermission||getClassLoader||Allows the driver to load the classes implementing the logging feature|
Creating an Extended Connector¶
Creating a connector using an Extended Driver is very similar to creating a connector with built-in support. Choose Database - Extended as the Type. The following fields will be available:
- Connection Name A name for this connection
- JDBC Driver Select the JDBC Driver you want to use for this connection
- Login ID The username the Masking Engine should connect to the target database with.
- Password The password to use to connect to the database
- JDBC URL You must provide the JDBC URL for the database to connect to. The exact format and available parameters are specific to the database you're connecting to. Consult your database vendors documentation for details.
Some databases allow you to specify usernames and passwords in the JDBC URL. It's best not to do this. The Delphix Masking Engine is careful not to log the Login ID and Password in the Masking Engine's logs, but JDBC URLs may be logged unmodified.
Once the connector is created, you can create rulesets, inventories, and jobs to profile and mask your data as with other types of connectors.
Extended Connectors can be edited and deleted in the same way as Built In Connectors
Connectors using extended JDBC Drivers can be synchronized similarly to other connectors. See Working with Multiple Masking Engines for details. When a job or connector requires an uploaded JDBC Driver, the driver will be exported along with the connector or job. JDBC Drivers are part of the Global Object and so will be synchronized whenever the Global Object is synchronized. They can also be synchronized individually.
