System requirements for configuring the Data Virtualization Remote Agent

System requirements

Hardware requirements

Table 1. Hardware requirements and descriptions

Hardware requirements	Description
Operating System support	Linux®, Windows or Mac OS operating systems, which can run IBM Java 8 or Oracle Java 8.
Memory	512 Mb in default configuration. Note: High concurrency or large files access might require a higher memory configuration.
Disk space	500 Mb for Remote Agent software. Note: Java Runtime Environment has its own system requirements.

Java requirements

IBM® SDK, Java Technology Edition, Version 8 is recommended for running the Data Virtualization Remote Agent and it is available for download from Java SDK downloads, version 8.0.

Note: Only the Java Runtime Environment (JRE) is required for use with the IBM Data Virtualization Remote Agent and not the full SDK.

The Data Virtualization Remote Agent also supports Oracle Java SE 8.

Network requirements

The Data Virtualization Remote Agent needs to be on a network that is configured to allow bidirectional communication with the Data Virtualization service instance and with any other Data Virtualization Remote Agents that you choose to deploy. Consider the following network requirements.

1. The Data Virtualization service instance running on IBM Cloud or within Red Hat® OpenShift® must be able to establish a network connection to the Remote Agent. If the Data Virtualization Remote Agent operates within a network that does not allow incoming connections, then consider the following options.
   • Configure the firewall to expose a network port so that the Data Virtualization service can connect with the remote connector.
   • Use a tunnelling service such as Secure Gateway or Satellite Connect.

     See Optional: Setting up access to the Data Virtualization Remote Agent with Secure Gateway.

2. The Data Virtualization Remote Agent must be able to connect with the Data Virtualization Service instance. Data Virtualization instances on IBM Cloud or on Red Hat OpenShift are already configured to allow this incoming connection, but your own network infrastructure might interfere with this communication. You might need to configure HAProxy or appropriate firewall rules to allow this communication.
3. Configure two network ports for the Data Virtualization Remote Agent as listed in the following table.

   Table 2. Network ports and descriptions

   Network port	Description
   Data communications port	This port defaults to 6414 and you can change it for each Remote Agent you want to deploy.
   Management port	Management functions port defaults to 7777 and you can change it. If you make a change, then apply it uniformly across all the agents that are deployed in your environment.

After you meet the system requirements to deploy the Remote Agent, proceed to generate the configuration details. See Generating the configuration for the Remote Agent.
