Apache Ignite Transactions Architecture: 2-Phase Commit Protocol
Apache Ignite supports a range of different Application Programming Interfaces (APIs). In this multi-part article series, we will take a more detailed look at how Apache Ignite manages transactions in its key-value API and some of the mechanisms and protocols it supports. Here are topics we will cover in this series:
* Ignite transactions and the two-phase commit protocol.
* Concurrency modes and isolation levels.
* Transaction handling at the level of Ignite persistence (WAL, checkpointing, and more).
* Transaction handling at the level of 3rd party persistence.
In this first part, we will begin with a discussion of the two-phase commit (2PC) protocol and then look at how this works with various types of cluster nodes. https://goo.gl/c82bGb #DataIntegration #ML
Lumira 2.1: X509 based Single Sign On support with BI Platform
This blog is intended to provide you an overview of the support for Multifactor authentication to perform Single-Sign-On to BI Platform (using X509) via Secure Login Client (SLC) in Lumira 2.1.
Starting from Version 4.2 SP05, BI platform offers support for X509 based multifactor authentication for various thin and thick clients. This means the clients like Lumira also supports x509 based Single-Sign-on to BI Platform
Pre-requisites:
* You have set up SAP Secure Login Client (SLC) on your desktop machine for authentication. It has a valid X.509 certificate stored.
*
You have configured SAP BI Platform to accept trusted X.509-based logon requests via RESTful connection.
*
You are using SAP BI Platform 4.2 SP05 version and above.
Refer to the additional References for more information…
Single Sign On with X509 using Lumira:
Once the above Pre-requisites are met, you can chose to enable X509 based logon option in the Lumira preferences –>Network option.
Since X509 is supported via RESTful, the URL needs to be configured.
Also since HTTPS WACS is a pre-requisite, providing a HTTP URL would not work here.
you need to restart the Lumira after configuration.
Logon to BI Platform with Single Sign On:
In the Home page go to the BI Platform tab and select “SSO Authentication” option and click on connect button. This would read the x509 based certificate available with the SAP Secure Login Client (SLC) installed on your desktop and provide single sing on to the BI Platform.
Once connected to BI Platform, all further communication for other workflows happens via the established session.
