1.1 About the Oracle Stream Analytics Installation

This document explains how to install a new Oracle Stream Analytics 12c (12.2.1.1) Oracle home.

After you install Oracle Stream Analytics (OSA), you can configure a standalone OSA domain. Note that an OSA standalone-server domain does not require Oracle WebLogic Server. For more information, see Standalone-Server Domains in Administering Oracle Stream Analytics. Optionally, you can integrate Apache Spark with your OSA installation, as described in Installing and Configuring Apache Spark.

If you are using a previous version of Oracle Event Processing (the prior name for OSA), note there is no upgrade to the OSA 12c (12.2.1.1) runtime software. If you created an Oracle Event Processing 11g standalone-server domain, then you must install a new OSA 12c (12.2.1.1) Oracle home and configure a new OSA 12c (12.2.1.1) standalone-server domain.

1.2 Roadmap for Verifying Your System Environment

Before you begin the installation and configuration process, you must verify your system environment.

The following table identifies important tasks and checks to ensure that your environment is properly prepared for installing and configuring OSA.

1.4.1 Starting the Installation Program

Before running the installation, you must verify the JDK and required software.

To start the installation program:

1. Sign in to the host system.

2. Verify that a certified JDK already exists on your system by running java -version from the command line. At the time of publication, the certified JDK for 12c (12.2.1.1) was 1.8.0_77. For more information, see the appropriate certification document on the Oracle Fusion Middleware Supported System Configurations page.

3. Verify that you have installed all prerequisite software.

4. Go to the directory where you downloaded the installation program.

5. Launch the installation program by running the java executable from the JDK directory on your system:

- On UNIX operating systems: /home/Oracle/Java/jdk1.8.0_77/bin/java —jar fmw_12.2.1.1.0_osa_generic.jar

- On Windows operating systems: Double-click on the installation icon, or enter in a command prompt C:\home\Oracle\Java\jdk1.8.0_77\bin\java -jar fmw_12.2.1.1.0_osa_generic.jar

Be sure to replace the JDK location in these examples with the actual JDK location on your system.

Note:

You can also launch the installer in silent mode using a saved response file instead of launching the installer screens. For more about silent or command line installation, see Using the Oracle Universal Installer in Silent Mode in Installing Software with the Oracle Universal Installer.

When the installation program appears, you are ready to begin the installation. See the next topic for a description of each installation program screen.

1.4.2 Navigating the Installation Screens

The installer shows a series of screens where you verify or enter information.

The following table lists the order in which installer screens appear. If you need additional help with an installation screen, click Help in the installer.

For more information about the directory structure after installation, see What are the Key Oracle Fusion Middleware Directories? in Understanding Oracle Fusion Middleware.

1.4.3.3 Viewing the Contents of the Oracle Home

You can view the contents of the Oracle home using the viewInventory script.

For more information, see Viewing the Contents of an Oracle Home in Installing Software with the Oracle Universal Installer.

1.5 Configuring the Oracle Stream Analytics Domain

An OSA installation does not include Oracle Fusion Middleware Infrastructure, so only standalone-server domains may be created for OSA. You can learn more about standalone-server domains by reading Standalone-Server Domains in Administering Oracle Stream Analytics.

For instructions on configuring a standalone domain, see Create a Standalone-Server Domain in Administering Oracle Stream Analytics. This document also contains other administrative tasks for OSA, including updating a domain and starting and stopping the servers in the domain.

1.6 Installing and Configuring Apache Spark

Apache Spark (Spark) is an open source big data processing framework built around speed, ease of use, and sophisticated analytics.

You can use Spark with Oracle’s Continuous Query Language (CQL) to scale complex event processing applications on commodity clusters. This means that Spark allows you to process larger volumes of streaming data at a lower cost.

Note:
OSA supports only cluster mode Spark deployments.

The installation steps presented here assume the following:

- OSA is installed in OSA_HOME.
For example, OSA_HOME=/apps/oracle/middleware.

- The OSA application domain has been created, named OSA_DOMAIN.
For example, OSA_DOMAIN=OSA_HOME/user_projects/domains/osa/defaultserver.

Note that there is no step specific to Spark installation when you create the OSA application domain.

- A Spark cluster is set up, using one of the cluster types supported by OSA (such as Spark standalone or Hadoop YARN). For links to the supported Spark version download and documentation, see Prerequisites for Apache Spark Integration.

When you are ready, use the information in the following sections to integrate Spark with OSA:

- Prerequisites for Apache Spark Integration

- Installing Apache Spark

- Installing the OSA-Spark Integration Component

- Installing Kafka

- Configuring the OSA Domain for Spark

- Configuring the osa.properties File

1.6.1 Prerequisites for Apache Spark Integration

Using Spark with OSA requires installing and configuring third party components.

The following table provides information about the components that are required in a Spark cluster environment to use Spark with OSA. This information is referenced from the subsequent topics that describe installing and configuring these components.

Component

Version

Links

Apache Kafka

0.8.2.2 for Scala 2.10

Download: http://kafka.apache.org/downloads.html
Documentation: http://kafka.apache.org/documentation.html

Hadoop YARN

2.6.X (recommended)

Download: http://hadoop.apache.org/releases.html

Apache Spark

1.5.X - Prebuilt for Hadoop 2.6 (or your Hadoop version)

Note: 1.6.X not supported

Download: http://spark.apache.org/downloads.html
Documentation: http://spark.apache.org/docs/1.5.1/

1.6.2 Installing Apache Spark

Install the version of Spark that is supported by your version of OSA.

To install Spark:

- Refer to Prerequisites for Apache Spark Integration to install Spark in SPARK_HOME.

Notes

- OSA supports only cluster mode Spark deployments.

- Install the version of Spark that is supported by your version of OSA. For 12c (12.2.1.1), see Prerequisites for Apache Spark Integration.

- If you want to use Spark together with Hadoop Distributed File System (HDFS) and YARN, install the Spark version that was compiled for the Hadoop version compatible with your current environment.

- Your Spark distribution must also contain SPARK_HOME/lib/spark-examples-X.X.X-hadoopY.Y.Y.jar, which is also required by OSA.

- Spark must be installed on each node in your cluster, and also on the node where the OSA domain runs.

- SPARK_HOME must have the same value on each node, including the OSA node. It makes sense to mount the same network drive to the same location on each node.

1.6.3 Installing the OSA-Spark Integration Component

The OSA-Spark integration component adds Oracle’s Continuous Query Language (CQL) support, along with an OSA-specific runtime environment, to the Spark framework to implement application deployment.

This component is delivered as part of the OSA server installation as a single JAR at OSA_HOME/oep/spark/lib/spark-osa.jar.

This JAR file must be copied to all worker nodes and also to the OSA node. Ideally, you copy this file into your Spark installation at SPARK_HOME/lib/spark-osa.jar.

1.6.4 Installing Kafka

Apache Kafka is required by an OSA-Spark environment to send and receive data.

Kafka is the only external system that an OSA-Spark exploration can accept data from or send data to. If you want to chain two explorations (where one is running in Spark, and the other running in either Spark or OSA), the only way to do this is to explicitly create Kafka targets and streams to connect these explorations. Additionally, Kafka is used to push data from an OSA-Spark exploration back to the “live output stream” of the exploration editor. This is configured in the osa.properties file using the osa.kafka properties (see Kafka Settings).

To install Kafka:

- Refer to the download and documentation links in Prerequisites for Apache Spark Integration.

Note:

- OSA only needs to know the Kafka endpoints, such as broker and zookeeper addresses.

- OSA uses short-lived Kafka topics to communicate with applications in Spark. To allow OSA to explicitly delete these topics, consider adding this line in the server configuration file KAFKA_HOME/config/server.properties (where KAFKA_HOME is the Kafka installation folder) when installing Kafka:

delete.topic.enable=true

1.6.5 Configuring the OSA Domain for Spark

OSA-Spark integration relies on settings in one or more configuration files.

To configure your OSA domain for Spark:

1. Stop the OSA server (OSA domain).

2. Create the Spark configuration folder in your domain as: OSA_DOMAIN/config/spark.

3. Create the OSA configuration file in the Spark configuration folder as: OSA_DOMAIN/config/spark/osa.properties.

4. Edit the OSA configuration file according your environment (see Configuring the osa.properties File).

5. Create any additional configuration files required by your environment in the Spark configuration folder. This may include files specific to Hadoop Distributed File System (HDFS) and YARN, such as yarn-site.xml, core-site.xml, hdfs-site.xml, and more. For details, refer to the documentation for your cluster.
These files are required by OSA to deploy files to your cluster. OSA needs client-side settings only (such as name node URL, resource manager URL, timeouts, credential settings, and so on). Do not copy the full server-side YARN/Hadoop configuration.

6. Edit the content of additional configuration files according your environment.

7. Start your OSA domain.

8. Access your OSA applications at the following URLs:

- OSA for Spark: http://host:port/sxspark

- OSA: http://host:port/sx

If you accept the default installation parameters, the URLs are:

- OSA for Spark: http://localhost:9002/sxspark

- OSA: http://localhost:9002/sx

Note:
Whenever you deploy an OSA streaming application, the content of the configuration folder is zipped and sent to the Spark cluster. In this way, the same configuration is available for the OSA streaming application while running in the cluster.

Tips

- Find useful configuration templates for different scenarios in OSA_HOME/oep/spark/config-templates. You can start with these files and customize them according to your needs.

- If you want to experiment with different Spark configurations, you can set up multiple configuration folders outside your OSA domain and set up the OSA_DOMAIN/config/spark folder as a symlink that points to one of your configuration folders at a time. For example, OSA_DOMAIN/config/spark points to your YARN-based OSA configuration in /apps/osa/config/yarn-cluster, and to your Spark Standalone cluster configuration in /apps/osa/config/spark-cluster. In this way, you can easily switch between your configurations.

1.6.6 Configuring the osa.properties File

The osa.properties file is the configuration file for OSA-Spark integration.

Refer to the following sections to set configuration properties:

- General Deployment Settings

- Kafka Settings

- JAR File Settings

- Runtime Settings

- Spark Settings

- Example osa.properties File

1.6.6.1 General Deployment Settings

General deployment settings in osa.properties define the Spark cluster type and distribution folder.

The following table describes the values for the general deployment settings in osa.properties.

Parameter

Description

osa.deploy.spark.master

Mandatory. Specifies the Spark cluster type and master URL.
You can configure OSA for Spark running on Spark Standalone or YARN cluster:

- Spark Standalone: The cluster type is identified by spark://in the URL. Important: you must provide the master's REST interface URL.
Example: osa.deploy.spark.master=spark://spark.mycompany.com:6066

- YARN: The cluster type is identified by the single word yarn. Instead of a master URL, you only enter yarn. Important: YARN and HDFS-specific client configuration files must be also provided in the configuration folder (yarn-site.xml, core-site.xml, hdfs-site.xml).
Example: osa.deploy.spark.master=yarn

osa.deploy.spark.fileshare

Mandatory for Spark Standalone. Not used for YARN. Specifies the shared location that can be used by OSA as a distribution folder for the applications. The folder must be accessible from every node under the same path. This can be an Network File System (NFS) or Hadoop Distributed File System (HDFS) path. If you want to use HDFS, client configuration files (core-site.xml, hdfs-site.xml) must be provided in the configuration folder.

Example: hdfs://hdfs.mycompany.com/osa/spark-deployments

1.6.6.2 Kafka Settings

Kafka settings in osa.properties define the Kafka brokers and zookeeper.

OSA exchanges data through Kafka with the streaming application running in Spark. For this reason you have to specify where your Kafka server is installed.

The following table describes the values for the Kafka settings in osa.properties.

Parameter

Description

osa.kafka.brokerlist

Mandatory. Comma-separated list of Kafka brokers in the form host:port.
Example: kafka.mycompany.com:9092

osa.kafka.zookeeper

Mandatory. The Kafka zookeeper in the form host:port.
Example: zk.mycompany.com:2181

1.6.6.3 JAR File Settings

JAR file settings in osa.properties define the paths to the Spark assembly and example JAR files.

OSA requires the spark-assembly and spark-examples packages of your Spark distribution on each worker node and on the OSA node. The path to each JAR must be the same on all nodes. Additionally, the spark-osa package must be copied to each node.

The following table describes the values for the JAR file settings in osa.properties.

Parameter

Description

osa.jars.spark-assembly

Mandatory. Path to the spark-assembly JAR file.

Example: /apps/spark/spark-1.5.1/lib/spark-assembly-1.5.0-hadoop2.6.0.jar

osa.jars.spark-examples

Mandatory. Path to the spark-examples JAR file.

Example: /apps/spark/spark-1.5.1/lib/spark-examples-1.5.0-hadoop2.6.0.jar

osa.jars.spark-osa

Mandatory. Path to the spark-osa JAR file, which you must coppy to each node manually.

Example: /apps/spark/spark-1.5.1/lib/spark-osa.jar

1.6.6.4 Runtime Settings

Runtime settings in osa.properties tune the deployed OSA streaming applications.

You can tune the deployed OSA streaming applications based on the available resources in your cluster and on the characteristics or nature of the problem that you want to solve with OSA.

The following table describes the values for the runtime settings in osa.properties.

Parameter

Default

Description

osa.runtime.executor.instances

1

Optional. Specifies how many workers will do stream processing in parallel. Note that this number will affect the required executor cores. This parameter value applies to each deployed OSA application.

osa.runtime.batchDuration

1000ms

Optional. Specifies the batch interval of the streaming data processing.

1.6.6.5 Spark Settings

Spark settings in osa.properties define resource consumption of the deployed Spark application in the cluster.

Note:
OSA may override your Spark property settings in osa.properties if they are not sufficient to run OSA streaming applications in the Spark cluster.

The following table describes the values for the Spark settings in osa.properties that are most typically used in the context of OSA-Spark. Setting values lower than the default values may result in an out of memory error. For more information about Spark property settings, see http://spark.apache.org/docs/1.5.1/configuration.html.

Parameter

Default (minimum)

Description

spark.executor.memory

1800m

Optional. Amount of memory to use per executor process.

spark.executor.cores

1

Optional. The number of cores to use on each executor. In standalone mode, setting this parameter allows an application to run multiple executors on the same worker, provided that there are enough cores on that worker. Otherwise, only one executor per application will run on each worker.

spark.driver.memory

1500m

Optional. Amount of memory to use for the driver process.

spark.driver.cores

1

Optional. Number of cores to use for the driver process, only in cluster mode.

1.6.6.6 Example osa.properties File

Review an example configuration in the osa.properties file.

osa.deploy.spark.master=spark://spark.mycompany.com:6066
osa.deploy.spark.fileshare=/osa-share/spark-deployments

osa.kafka.brokerlist=kbroker1.mycompany.com:9092,kbroker2.mycompany.com:9092
osa.kafka.zookeeper=zk.mycompany.com:2181

osa.jars.spark-assembly=/apps/spark/spark-1.5.1/lib/spark-assembly-1.5.0-hadoop2.6.0.jar
osa.jars.spark-examples=/apps/spark/spark-1.5.1/lib/spark-examples-1.5.0-hadoop2.6.0.jar
osa.jars.spark-osa=/apps/spark/spark-1.5.1/lib/spark-osa.jar

osa.runtime.executor.instances=1
osa.runtime.batchDuration=1000ms

spark.executor.cores=2
spark.executor.memory=3g
spark.driver.memory=2500m

This example shows:

- Spark runs in a standalone cluster and the OSA applications are distributed through an NFS file share mounted to /osa-share/spark-deployments on each node.

- Kafka is installed and configured, and has has two dedicated broker servers and a separate zookeeper server.

- Spark 1.5.1 is installed on each node to /apps/spark/spark-1.5.1.

- Runtime parameters specify that there is no parallel processing (single processor instance) and batch interval is set to 1 second.

- Spark-specific parameters specify spark.executor.cores=2 (defaults to 1), spark.executor.memory=3g (defaults to 1500m as the minimum), and spark.driver.memory=2500m (defaults to 1800m as the minimum)

- This configuration does not use HDFS or YARN, so the osa.properties file is the only configuration file that must be copied to the configuration folder.

1.7 Deinstalling the Software

Follow the instructions in this section to start the product deinstaller and remove the software.

If you want to perform a silent (command-line) deinstallation, see Running the Oracle Universal Installer for Silent Deinstallation in Installing Software with the Oracle Universal Installer.

1.7.1 Starting the Deinstallation Program

You can start the deinstaller on either Unix or Windows.

To start the deinstaller:

- On Unix
Go to the ORACLE_HOME/oui/bin directory and enter the following command:

./deinstall.sh

- On Windows
Do one of the following:

- Use a file manager window to go to the ORACLE_HOME\oui\bin directory and double click on deinstall.cmd.

- From the command line, go to the ORACLE_HOME\oui\bin and enter the following command:

deinstall.cmd

- From the Start menu, select All Programs, then select Oracle, then select OracleHome, and then select Uninstall Oracle Software.

1.7.2 Navigating the Deinstallation Screens

The deinstaller shows a series of screens to confirm the deinstallation of the software.
