The GemFire XD JDBC implementation enables you to use a distributed
system as an embedded JDBC datasource in products such as WebLogic Server.
Follow this general procedure when setting up GemFire XD as a datasource
in a third-party product:
- Copy the gemfirexd-client.jar file to the location where other
JDBC drivers for the product are stored.
- For products such as WebLogic Server that provide
datasource templates, select "Apache Derby," "User-defined," or "Other" as
the database type if GemFire XD is not explicitly supported.
- Specify "gemfirexd" as the
database name. This represents a single GemFire XD distributed system. (GemFire XD
does not contain multiple databases as in Apache Derby or other relational
- For the hostname and port,
specify the hostname and port combination of a GemFire XD locator or a GemFire XD
server. This is the same hostname and port combination you would use to connect
as a client from the
- For the database username
and password, enter a valid username and password combination if you have
enabled authentication in your system (using the
If you have not configured authentication in GemFire XD, specify
"app" as both the username and password values, or any other temporary value.
Note: GemFire XD uses the username specified in the JDBC connection as
the schema name when you do not provide the schema name for a database object.
GemFire XD uses "APP" as the default schema. If your system does not enable
authentication, you can specify "APP" for both the username and password to
maintain consistency with the default schema behavior.
- For the driver class, specify:
- The JDBC URL that you
specify must begin with
jdbc:gemfirexd://. Remove any template properties such
create=true if they are present in the URL or
In products such as WebLogic, you cannot specify JDBC connection
properties for an embedded datasource as part of the JDBC URL. Instead, use the
properties field and specify connectionAttributes using the format:
See also the Apache Derby documentation for
- A process can connect to
only one GemFire XD distributed system at a time. If you want to connect to a
different GemFire XD distributed system, shut down the current embedded data
source before re-connecting with a different datasource.
