Prepare the Environment

Before you install the

MDM Hub

, prepare the installation environment.

The following table describes the tasks you perform to prepare the environment for the installation:

Task	Description
Verify minimum system requirements	Verify that the machines meet the hardware and software requirements for the MDM Hub installation. The hardware requirements are dependent on the data, processing volumes, and business rules. To install the MDM Hub, the machines must meet the following minimum requirements: Disk space. 4.9 GB RAM for the development environment. 4 GB To verify the run-time physical memory requirements of the MDM Hub components, use the following formula: Total run-time memory requirement for MDM Hub components = JDK JVM max heap size of the application server + operating system native heap size
Install Java Development Kit (JDK)	Install a supported version of the JDK on the machine on which you want to install the MDM Hub . The JDK is not bundled with the MDM Hub installers. In a JBoss environment, you must install the version of Azul Zulu JDK that Informatica provides. Contact Informatica Shipping to download Azul Zulu JDK. Use the same Java version on the application server machines and on the machines on which you want to launch the Hub Console.
Install Visual C++ Redistributable for Visual Studio 2019 on Windows only	On Windows systems, Multidomain MDM requires Visual C++ Redistributable for Visual Studio 2019 to support the name search feature and the matching feature.
Set environment variables	Set the environment variables for the MDM Hub installation. To use the correct JDK, set the following environment variables to point to the JDK directory: JAVA_HOME. Required PATH. Required To set the correct locale behavior for Oracle, set the NLS_LANG environment variable for client application environments such as the Oracle loader, and the MDM Hub components. Specify the NLS_LANG parameter in the following format: NLS_LANG = <language>_<territory>.<character set> To store and search for records that contain Chinese, Japanese, Korean, or accented characters, set the character set to UTF-8. For more information about NLS_LANG settings, see the Oracle documentation.
Set the operating system locale	Set the same operating system locale for the Hub Server, the MDM Hub Master Database, Operational Reference Store, and the Hub Console.
Set up the X Window System on UNIX	If you want to run the installer in graphical mode on UNIX, set up an X Window System. An X Window System is a graphics display server. For more information about setting up an X Window System, see the documentation for your operating system.
Disable access to the root welcome page for your application server	To improve security, disable access to the root welcome page for your application server. For instructions, see the documentation for your application server.
Disable insecure TLS cipher suites	To improve security, in the Java runtime environment that is used with Multidomain MDM , disable insecure TLS cipher suites. Open the following file: ../jdk<version>/jre/lib//security/java.security Find the property jdk.tls.disabledAlgorithms and update the value to include the following list of insecure cipher suites: jdk.tls.disabledAlgorithms = SSLv3, RC4, MD5withRSA, DH keySize < 1024, EC keySize < 224, DES40_CBC, RC4_40, 3DES_EDE_CBC, EDH-RSA-DES-CBC3-SHA, ECDHE-RSA-DES-CBC3-SHA, DES-CBC3-SHA For more information about the property, see the documentation for your JDK.
