WSO2 Data Analytics Server (WSO2 DAS) is shipped with default configurations that allow you to download, install and get started with your product instantly. However, when you go into production, it is recommended to change some of the default settings to ensure that you have a robust system that is suitable for your operational needs. Also, you may have specific use cases that require specific configurations to the server. If you are a product administrator, the follow content provides you with an overview of the administration tasks that you need to perform when working with Data Analytics Server (WSO2 DAS).


Upgrading from a previous release

If you are upgrading from WSO2 DAS 3.0.1 to WSO2 DAS 3.1.0, see Upgrading from WSO2 DAS 3.0.1.


Changing the default database

To change the default database configurations for WSO2 DAS, see Working with Databases.


Configuring users, roles and permissions

The user management feature in your WSO2 DAS allows you to create new users and define the permissions granted to each user. You can also configure the user stores that are used for storing data related to user management.

Configuring security

After you install WSO2 DAS, it is recommended to change the default security settings according to the requirements of your production environment. As WSO2 DAS is built on top of the WSO2 Carbon Kernel (version 4.4.x), the main security configurations applicable to WSO2 DAS are inherited from the Carbon kernel.

Important!

If you are configuring your production environment, be sure to check the Security Guidelines for Production Deployment before applying any security configurations.

For instructions on configuring security in your server, see the following topics in the WSO2 Administration Guide.


Configuring transports

The WSO2 Carbon Kernal on which WSO2 DAS is built on supports a variety of transports. 

For instructions on configuring these transports, see WSO2 Administration Guide - Working with Transports.


Configuring multitenancy

You can create multiple tenants in your DAS server which allows you to maintain tenant isolation in a single server/cluster. For instructions on configuring multiple tenants for your server, see WSO2 Administration Guide -  Working with Multiple Tenants.


Configuring the registry

registry  is a content store and a metadata repository for various artifacts such as services, WSDLs and configuration files. In WSO2 products, all configurations pertaining to modules, logging, security, data sources and other service groups are stored in the registry by default. 

For instructions on setting up and configuring the registry for your server, see WSO2 Administration Guide - Working with the Registry.


Performance tuning

You can optimize the performance of your WSO2 server by using configurations and settings that are suitable to your production environment. At a basic level, you need to have the appropriate OS settings, JVM settings etc. Since WSO2 products are all based on a common platform called Carbon, most of the OS, JVM settings recommended for production are common to all WSO2 products. Additionally, there are other performance enhancing configuration recommendations that depend on very specific features used by your product. 

For instructions on the Carbon platform-level performance tuning recommendations, see WSO2 Administration Guide - Performance Tuning.

For instructions to tune performance for a Spark cluster, see Tuning Performance for a Spark Cluster.

For instructions to tune performance for real time analytics, see Tuning Performance for Real Time Analytics.


Changing the default ports

When you run multiple WSO2 products, multiple instances of the same product, or multiple WSO2 product clusters on the same server or virtual machines (VMs), you must change their default ports with an offset value to avoid port conflicts.

For instructions on configuring ports, see WSO2 Administration Guide - Changing the Default Ports.


Managing product features

Each WSO2 product is a collection of reusable software units called features where a single feature is a list of components and/or other feature. By default, WSO2 DAS is shipped with the features that are required for your main use cases. 

For information on installing new features, or removing/updating an existing feature, see WSO2 Administration Guide - Working with Features.


Configuring custom proxy paths

This feature is particularly useful when multiple WSO2 products (fronted by a proxy server) are hosted under the same domain name. By adding a custom proxy path you can host all products under a single domain and assign proxy paths for each product separately . 

For instructions on configuring custom proxy paths, see WSO2 Administration Guide - Adding a Custom Proxy Path.


Customizing error pages

You can make sure that sensitive information about the server is not revealed in error messages, by customizing the error pages in your product. 

For instructions, see WSO2 Administration Guide - Customizing Error Pages.


Customizing the Management Console

Some of the WSO2 products, such as WSO2 DAS consist of a web user interface named the management console. This allows administrators to configure, monitor, tune, and maintain the product using a simple interface. You can customize the look and feel of the management console for your product.

For instructions, see WSO2 Administration Guide - Customizing the Management Console. 


Applying Patches

For instructions on applying patches (issued by WSO2), see WSO2 Administration Guide - WSO2 Patch Application Process.


Monitoring the server

Monitoring is an important part of maintaining a product server. Monitoring capabilities available for WSO2 DAS are listed below.
