You can run multiple wire listeners.
About this task
By running multiple wire listeners, you can use a
combination of the APIs that are supported by the wire listener: MongoDB, REST, and MQTT. Create a configuration file
for each listener type that you want to run. For example, you can create a configuration file for
the MongoDB API and a configuration file for
the REST API or the MQTT protocol. You can start all wire listeners with the same
start command by providing multiple -config arguments.
Procedure
- Create the individual configuration files in the $INFORMIXDIR/etc directory.
You can use the $INFORMIXDIR/etc/jsonListener-example.properties file
as a template.
- Customize each configuration file and assign a unique name.
Important: The url parameter
must be specified, either in each individual configuration file or
in the file that is referenced by the include parameter.
- Specify the include parameter to
reference an additional configuration file. The path can be relative
or absolute. If you have multiple configuration files, you can avoid
duplicating parameter settings in the multiple configuration files
by specifying a subset of shared parameters in a single configuration
file, and the unique parameters in the individual configuration files.
- Start the wire listeners.
Example: Running multiple wire listeners that share
parameter settings
In this example, the same url, authentication.enable,
and security.sql.passthrough parameters are used
to run two wire listeners:
- Create a configuration file named shared.properties that includes the
following
parameters:
url=jdbc:informix-sqli://localhost:9090/sysmaster:INFORMIXSERVER=ol_informix1210;
authentication.enable=true
security.sql.passthrough=true
- Create a configuration file for use with the MongoDB API
that is named mongo.properties, with the parameter include=shared.properties set:
include=shared.properties
listener.type=mongo
listener.port=27017
- Create a configuration file for use with the REST API that is
named rest.properties, with the parameter include=shared.properties set:
include=shared.properties
listener.type=rest
listener.port=8080
- From the command line, run the start command. Include separate
-config
arguments for each wire listener API
type.java -jar $INFORMIXDIR/bin/jsonListener.jar
-config json.properties
-config rest.properties -start
