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.
1. Open the axis2.xml file and comment out the following. Note that this step is redundant in the Traffic Manager profile since the axis2_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>
```
2. 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) Note that the WSO2 has deprecated the Gateway Manager profile.
Key Manager	`authenticationendpoint` `client-registration#v0.12` `oauth2` `throttle#data#v1 api#identity#consent-mgt#v1.0`
API Publisher	`am#sample#pizzashack#v1` (Only needed if the Pizzashack sample API is used) `api#am#publisher#v0.12` `authenticationendpoint micro-gateway#v0.9`
API Store (Developer Portal)	`api#am#store#v0.12` `authenticationendpoint`

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:
Profile
Required Jaggery apps
Gateway Worker None
Key Manager None
Traffic Manager None
Publisher publisher, admin
Store None

Run the required API-M profile.
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.
