Prerequisites
Before you install or update ZD&T Personal Edition, you need to check the hardware and software requirements, and set up the base Linux® system.
Hardware and software requirements
For a complete list of ZD&T hardware and software requirements, you can generate the report from Software Product Compatibility Reports.
- 4.1 GB is required to download files.
- There are 33 extracted files. 15 GB is needed for one of the files, and 8 GB is needed for each of others.
- 300 GB is needed to hold the ADCD files.
Setting up the base Linux system
- You have access to internet on your machine.
- You have root or sudo access to the Linux operating system.
- Your Linux system is configured to download the required
Linux packages. You can use
yum install
orapt-get
commands to install the package that might be required during the installation procedure.
- Acquiring Linux knowledge
To set up the base Linux system, you need to have some Linux knowledge to ensure that you can go through some basic concepts and commands from internet. The following commands might be required to use when you install the package.
- Obtaining access to software repository to run
YUM
orapt-get
commandsMake sure that you have access to software repository to run
YUM
commands on RHEL machine, or your Ubuntu machine have access to runapt-get
commands. ZD&T Installer will install all required packages. However, if you don't want ZD&T installer to install the required packages that are listed below, you need to install the packages before you start ZD&T Installer.YUM
commands on RHEL operating systemyum -y install iptables yum -y install libstdc++.i686 yum -y install perl yum -y install zip yum -y install unzip yum -y install gzip yum -y install bc
- Additional
YUM
commands on RHEL 8 operating systemyum -y install ncurses-libs yum -y install libnsl
apt-get
commands on Ubuntu operating systemapt-get -y install iptables dpkg --add-architecture i386 apt-get -y update apt-get -y install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 lib32stdc++6 apt-get -y install perl apt-get -y install zip apt-get -y install unzip apt-get -y install gzip apt-get -y install bc apt-get -y install libasound2 apt-get -f install
- Setting up the system time
Set your hardware clock to Coordinated Universal Time (UTC) to avoid problems when Daylight Saving Time starts and stops. The license server is sensitive to the hardware clock time and does not operate if the time appears to move backward. If the machine is shared with another operating system that expects local time (instead of UTC time), you might experience a one-hour non-operational time when you shift from Daylight Saving Time to the standard time.
- Installing a TN3270e client for the MVS™ consoleThe following TN3270e clients are examples of clients that can be used with the recent ZD&T offerings:
- x3270 (recent versions)
- Recent Personal Communications releases that run on Windows systems.
x3270-3.2.20-467.1.x86_64.rpm
- Managing the firewall and other security functionsYou must manage the firewall and other security functions that you install with your Linux. To simplify the configuration and operation, disable any firewall when you first work with zPDT®. If your firewall is based on iptables, as is common for most current Linux releases, commands such as those shown in the following example might be used. This example is for setting a rule to allow any emulated local 3270 session traffic through the firewall, and then displaying the rules for the filter table afterward.
$ su (switch to root) # iptables -I INPUT -p tcp --dport 3270 -j ACCEPT # iptables -L -n # exit (leave root)
