Installing

Keep these things in mind when installing:

Activation files

Activation files (activation.jaw) are used to enable product functionality. For example, The install package contains the needed activation file to enable communication between Host Access for the Cloud and MSS. It is typically activated as part of the install process. Activation files are downloaded from the Micro Focus download site and are specific for the different editions and platforms supported by Host Access for the Cloud. To work in a production environment, activation is required.

If activation was not part of the installation, you need to open the Administrative Console and complete the activation process (Configure Settings > Product Activation). See Upgrading from previous versions for information on handling activation files when you upgrade.
IIS Reverse Proxy with Host Access for the Cloud

If you plan on using the IIS Reverse Proxy, read Accessing Host Access for the Cloud using the IIS Reverse Proxy for prerequisites and configuration instructions.
Security

Host Access for the Cloud supports TLS and SSH protocols to protect mission-critical data. To secure your passwords and other sensitive data, you should require browsers to use the HTTPS protocol.

Installing on different platforms

Host Access for the Cloud and Java

The session server requires a Java JDK version 8 or higher and MSS requires a Java JRE version 8 or higher. This Java requirement is met during installation, except for systems, such as Linux on System Z that require an IBM JDK. Information on using the nojdk option is available under Installing on z/Linux.

Both Host Access for the Cloud and MSS require that the Java installation support unlimited strength encryption. More information is available on the Java web site.

If necessary, you can use the environment variables specified in the nojdk option and INSTALL4J_JAVA_HOME_OVERRIDE to specify a specific Java installation.

Windows

A basic Windows installation is described in Getting Host Access for the Cloud.

UNIX

You must either install as “root” or use a user account with root privileges to complete successfully. When the installation has successfully completed, the installed application can be started and managed by “root” or someone running as ‘root”.
If you are running on Linux platforms, follow these steps to set the session server to start automatically when your system first boots up.
Elevated privileges are needed to open any application ports lower than 1024. Host Access for the Cloud will not start using a lower port number unless you have system privileges to open low numbered ports.
You can use the chmod command to assign application privileges to users other than root.
If you are installing on a headless Linux system and there are no fonts installed on the system, you may encounter this font-related error: java.lang.Error: Probable fatal error: No fonts found. Ensure that fontconfig or at least one font is installed on the system in order to proceed with the installation.

z/Linux (SUSE E11.x and RHEL 6.x)

For systems, such as Linux on System Z, that require an IBM JDK, you can use the “nojdk” installer media, which does not include a bundled JDK.

The installation must be able to locate a Java executable to start. If a Java executable cannot be found by the installer, then you can set the INSTALL4J_JAVA_HOME environment variable to refer to a Java installation’s bin directory.
When started, the installation program will automatically search for version-compatible JDKs on the system. If more than one JDK is found, a list is displayed from which you can choose. If only a JRE is found on the system, you can continue with the installation, but the Host Access for the Cloud server will not run correctly until you have updated the wrapper.java.command property located in sessionserver/conf/container.conf to refer to a JDK installation.

If necessary, you can use the environment variables named above and INSTALL4J_JAVA_HOME_OVERRIDE to specify a specific Java installation.

Upgrading from previous versions

WARNING:If you are upgrading, it is important that you remove any activation files from MSS associated with prior versions of Host Access for the Cloud. Leaving obsolete activation files in place may result in limited access to sessions.

It’s best to back up any previous work before you upgrade.

From the Micro Focus download site, download the install package and activation files for the version you are upgrading to.
Remove any activation files from MSS associated with prior versions of Host Access for the Cloud. Leaving obsolete activation files in place may result in limited access to sessions.
Install Host Access for the Cloud.
If not handled during the installation process, install the new activation file or files into MSS using Administrative Console > Configure Settings > Product Activation.

Additional configuration

To continue using server side events or other customizations created in previous versions of Host Access for the Cloud, there are some minor manual steps to undertake after upgrading:

Server-side Events - Copy your server-side event JAR files located in /webapps/zfe/WEB-INF/lib to /microservices/zfe/extensions/server.
Client extensions - Copy the contents of webapps/zfe/custom to /microservices/zfe/extensions/client. Re-enable extensions.

Troubleshooting the Installation

To complete a successful installation, make sure that you have taken care of these common issues:

	Are the activation files installed and activated in the Administrative Console? MSS uses activation files to enable product functionality. With your installation you received an activation file associated with the type of host you are connecting to. For example, if you are licensed for the Unisys Edition, if not handled as part of the install process, you will need to open the Administrative Console, go to Configure Settings > Product Activation and verify that the Host Access for the Cloud Unisys activation file is in place.
	Is MSS configured for HTTPS? Connect to the system where the Administrative Server is installed and log in to the Administrative Server. In the Administrative Console, open the Security Setup section and note the protocol selection.
	Verify that both MSS and Host Access for the Cloud are using trusted certificates. MSS imports certificates and private keys to C:\ProgramData\Micro Focus\MSS\MSSData\certificates. See Securing connections. If you are not using trusted certificates, have you configured Host Access for the Cloud to run using HTTP?
	Are your connection properties configured properly? In the unlikely event that you have to verify connection information, the container.properties file for both the management component and the session server contains the connection properties needed to make the session server to MSS connection as well as the browser to session server connection. You can find the file in the Host Access for the Cloud installation at <install-dir>/sessionserver/conf/container.properties.
	Install does not complete on UNIX or Linux platforms The install program may stall on UNIX or Linux systems, particularly headless ones. This stall is caused by an insufficient amount of entropy in the system, typically due to a lack of interaction with the operating system’s UI (or lack of UI). To remedy the issue: Stop the installation process. On the installer’s command line, prepend –J to the Java System property: ./hacloud-xxxx-linux-x64.sh -J-Djava.security.egd=file:///dev/urandom Run the installation program containing the added argument.
