Product Profiles
When a WSO2 product starts, it starts all components, features and related artifacts bundled with it. Multi-profile support allows you to run the product on a selected profile so that only the features specific to that profile along with common features start up with the server.
Starting a product on a preferred profile only blocks/allows the relevant OSGI bundles. As a result, even if you start the server on a profile such as the api-store
for example, you can still access the API Publisher web application.
OSGI Bundle
OSGI bundle is a tightly coupled, dynamically loadable collection of classes, jars, and configuration files that explicitly declare their external dependencies (if any). In OSGi, a bundle is the primary deployment format. Bundles are applications that are packaged in JARs, and can be installed, started, stopped, updated, and removed.
API-M Profiles
The following are the different profiles available in WSO2 API Manager.
Profile | Command Option with Profile Name | Description |
---|---|---|
Gateway worker | -Dprofile=gateway-worker -DworkerNode=true | Only starts the components related to the API Gateway. You use this when the API Gateway acts as a worker node in a cluster. This profile starts the backend features for data processing and communicating with the manager node. |
Key Manager | -Dprofile=api-key-manager | Only starts the features relevant to the Key Manager component of the API Manager. |
Traffic Manager | -Dprofile=traffic-manager | Only starts the features relevant to the Traffic Manager component of the API Manager. The Traffic Manager helps users to regulate API traffic, make APIs and applications available to consumers at different service levels, and secure APIs against security attacks. The Traffic Manager features a dynamic throttling engine to process throttling policies in real-time, including rate limiting of API requests. |
API Publisher | -Dprofile=api-publisher | Only starts the front end/backend features relevant to the API Publisher. |
Developer Portal (API Store) | -Dprofile=api-store | Only starts the front end/backend features relevant to the Developer Portal (API Store). |
Prior to WSO2 API Manager 2.1.0, the Publisher and Gateway were required to be on two different cluster domains. However, from WSO2 API Manager 2.1.0 onward clustering is no longer a necessity, because the Publisher can play the role of the Gateway Manager. Therefore, now, the Gateway Manager profile (-Dprofile=gateway-manager)
has been deprecated as it is redundant.
Starting an API-M profile
It is recommended to start the components in the following order: Key Manager, Publisher, Store, Traffic Manager, and Gateway.
Perform the following configurations on the profile.
Carryout the following configuration changes on all the profiles with the exception of the Gateway profiles.
Open the
axis2.xml
file and comment out the following. Note that this step is redundant in the Traffic Manager profile since theaxis2_TM.xml
file is copied over.<transportSender name="ws" class="org.wso2.carbon.websocket.transport.WebsocketTransportSender"> <parameter name="ws.outflow.dispatch.sequence" locked="false">outflowDispatchSeq</parameter> <parameter name="ws.outflow.dispatch.fault.sequence" locked="false">outflowFaultSeq</parameter> </transportSender>
- Delete the
WebSocketInboundEndpoint.xml
file from the<API-M_HOME>/repository/deployment/server/synapse-configs/default/inbound-endpoints
directory.
Make sure to keep the following web apps, which are required, and remove the unnecessary web apps from the
<API-M_HOME>/repository/deployment/server/webapps
directory of each node.The following are the web apps required for each node:
Profile Required web apps Gateway Worker am#sample#pizzashack#v1
(Only needed if the Pizzashack sample API is used)
api#am#admin#v0.12
(Only needed if you want to perform administrative tasks through Gateway Manager)

Make sure to keep the required Jaggery apps and remove the unnecessary Jaggery apps from the
<API-M_HOME>/repository/deployment/server/jaggeryapps
directory of each node.The following are the Jaggery apps that are required for each node:

Execute one of the following commands based on your OS:You can start only one profile at a time.
OS Command & Example Windows <PRODUCT_HOME>/bin/wso2server.bat -Dprofile=<preferred-profile> --run
For example to start the API Store execute the following command.
<API-M_HOME>/bin/wso2server.bat -Dprofile=api-store --run
Linux/Solaris sh <PRODUCT_HOME>/bin/wso2server.sh -Dprofile=api-store
For example to start the API Store execute the following command.
sh <API-M_HOME>/bin/wso2server.sh -Dprofile=api-store
How multi-profiling works
Starting a product on a preferred profile starts only a subset of features bundled in the product. In order to identify what feature bundles apply to which profile, each product maintains a set of bundles.info
files in the <PRODUCT_HOME>/repository/components/<profile-name>/configuration/org.eclipse.equinox.simpleconfigurator
directories. The bundles.info
files contain references to the actual bundles. Note that <profile-name>
in the directory path refers to the name of the profile. For example, when there's a product profile named webapp, references to all the feature bundles required for webapp profile to function are in a bundles.info
file saved in the <PRODUCT_HOME>/repository/components/webapp/configuration/org.eclipse.equinox.simpleconfigurator
directory.
Note that when you start the server without using a preferred profile, the server refers to the <PRODUCT_HOME>/repository/components/default/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info
file by default. This file contains references to all bundles in the <PRODUCT_HOME>/repository/components/plugins
directory, which is where all components/bundles of a product are saved.
