ForgeRock: Open AM. Install Open AM 5.5 with Tomcat 8.0 - Part 1- Install Tomcat

This BLOG thread discusses on steps to install and configure Open AM 5.5 with Tomcat 8.0.

  • Install Tomcat.

You can always find the latest stable version of Apache Tomcat 8 from its official download page, which is 8.0.33 as of writing.
    • Under the "Binary Distributions" section and then the "Core" list, use the link pointing to the "tar.gz" archive to compose a wget command: 

  • Execute the command 

sudo tar -zxvf apache-tomcat-8.5.24.tar.gz -C /opt/tomcat --strip-components=1

  • Prior to running Apache Tomcat, you need to setup proper permissions for several directories:

cd /opt/tomcat
sudo chgrp -R tomcat conf
sudo chmod g+rwx conf
sudo chmod g+r conf/*
sudo chown -R tomcat logs/ temp/ webapps/ work/

sudo chgrp -R tomcat bin

ForgeRock IAM : OpenDS (Open Directory Server). Importing LDIF files

The most efficient method of importing LDIF data is to take the OpenDJ server offline. Alternatively, you can schedule a task to import the data while the server is online.

Importing from LDIF overwrites all data in the target backend with entries from the LDIF data.

In this thread, i am using cygwin to import the Data into OpenDS. Open DS is running on Widows server.

./import-ldif.bat --hostname "Mindtelligent-T7EJ1A7" --port 4444 --bindDN "cn=Directory Manager" --bindPassword password --backendID userRoot --includeBranch dc=example,dc=com --ldifFile c:\\Users\\hsing\\Downloads\\Example.ldif  --trustAll

I use Apache Directory Server validate if import is successful.

    • Number of Partitions: 2
    • Retention Period (Hours): 24
    Service page of Create Service wizard
    Note: The platformdemo is the name of the Oracle Event Hub Cloud Service - Platform cluster in which the topic will be created. You can provide a different name if you want to host this in a different Oracle Event Hub Cloud - Platfrom cluster.
  4. In the Confirm page, if you find the details appropriate, click Create.
    Confirmation page of Create Service wizard
  5. The control returns to the Services page. In the Services page, you could now see the new topicdemo service listed.

Apache Kafka and Apache Spark: A "Data Science Match" made in heaven.

Kafka is a publish-subscribe messaging system that provides a reliable Spark Streaming
source. The Kafka project introduced a new consumer API between versions 0.8 and 0.10, so there are 2 separate corresponding Spark Streaming packages available. The API provides one-to-one mapping between Kafka's partition and the DStream generated RDDs partition along with access to metadata and offset.

The following diagram shows end-to-end integration with Kafka, consuming messages from it, doing simple to complex windowing ETL, and pushing the desired output to various sinks such as memory, console, file, databases, and back to Kafka itself.

An overview of what our end-to-end integration will look like.

Following set of properties will need to be added to Spark Streaming API to integrate Kafka with Spark as a Source

bootstrap.servers: This describes the host and port of Kafka server(s) separated by a comma.

key.deserializer: This is the name of the class to deserialize the key of the messages from Kafka.

value.deserializer: This refers to the class that deserializes the value of the message. This uniquely identifies the group of consumer.

auto.offset.reset: This is used messages are consumed from a topic in Kafka, but does not have initial offset in Kafka or if the current offset does not exist anymore on the server then one of the following options helps.
