It is also available on the AIX or Linux server CD. See the README file for the associated server for details. The documentation is also available on the Internet at: https://www.ibm.com/support/pages/node/317755 2. Installation information ---------------------------- The IBM Remote API Client for Linux on System z is shipped as a compressed tar file (tgz) on the Remote API Clients CD. The tgz file contains the RPMS, install shell scripts, and licensing tool. You will need an FTP server or other method of transferring files into the Linux for System z server. This file has details for the IBM Remote API Client for Linux on System z If you are installing the client on a different platform see the README file in the proper ibm-commserver-clients subdirectory on the Remote API Clients download image. If you are installing one of the server components see the appropriate README file in the root directory on the server CD of the install media. 2.1 Hardware requirements -------------------------- IBM Remote API Client for Linux on System z requires a System z14, or later, server supported by one of the Linux distributions listed in section 2.2.1 Linux operating system version. Use the 'uname -m' command to verify the CPU class. It must report 's390x' to indicate a 64-bit environment. 2.2 Software requirements -------------------------- 2.2.1 Linux operating system version ------------------------------------- This version of IBM Remote API Client has been tested with the following Linux operating system versions. It may also run satisfactorily on other Linux distributions. RedHat Enterprise Linux 7.9 RedHat Enterprise Linux 8 (RHEL 8) RedHat Enterprise Linux 8.x RedHat Enterprise Linux 9 (RHEL 9) RedHat Enterprise Linux 9.x SUSE Linux Enterprise Server 12 (SLES12) SPx SUSE Linux Enterprise Server 15 (SLES15) SPx Ubuntu LTS 18.04 Ubuntu LTS 20.04 Ubuntu LTS 22.04 For each operating system version you also need to have loaded a set of optional RPMs. Some of these RPMs come from the Linux install media and some need to be downloaded (the URLs or FTP sites for the download sites are described later). Each of the RPMs which you need to download are noted with "(download)". For the 64-bit distributions, some 31-bit ('s390.rpm') packages are needed in addition to the 64-bit ('s390x.rpm') packages. These are noted in the lists below. Use the "rpm -q -a" command to see what packages are currently installed. The lists below specify the minimum recommended levels of these RPMs. Later levels should also work.

Using the latest Java 8 SDK from the web site below satisfies all the requirements. http://www.ibm.com/developerworks/java/jdk Install the Java SDK package with a command like: rpm -i ibm-java2-s390-sdk-8.0-6.0.s390.rpm and/or rpm -i ibm-java2-s390x-sdk-8.0-6.0.s390x.rpm 2.2.3 HTTPS ----------- The HTTPS support for Remote API Client is not recommended any longer due to more secure and efficient means for securing TCP/IP client/server flows. When considering secure socket connections between client/server, technologies like VPN, Socket-Tunneling are more efficient and can secure all the TCP/IP sockets between a client and a data center or server. 2.3 Installation process ------------------------- If you have a previous level of IBM Remote API Client already installed, follow the steps in section 3 to remove it before installing this new level. Any old configuration information will be left in place for use by the new installation. To install IBM Remote API Client for Linux on System z follow these instructions. - Copy or FTP the ibm-commserver-client-7.1.1.0-s390.tgz file from the ibm-commserver-clients/linux-systemz directory on the Remote API Clients CD to the Linux for System z server. Make sure to use binary mode for the tgz file. - Log into the Linux for System z server as root. - Uncompress and unpack the tar file into an empty temporary directory: mkdir /tmp/ibmcs cd /tmp/ibmcs tar -xzf ibm-commserver-client-7.1.1.0-s390.tgz - Run the installibmcscli shell script ./installibmcscli The installibmcscli shell script will test for certain prerequisites and issue warning messages if they are not met. You will be prompted to read and accept the license agreement, then the installibmcscli tool will install the RPMs. - Add the IBM Remote API Client binary directories to your PATH. You may wish to change your profile to do this automatically. export PATH="$PATH:/opt/ibm/sna/bin" export LD_LIBRARY_PATH=/usr/lib:/opt/ibm/sna/lib export LD_RUN_PATH=/usr/lib:/opt/ibm/sna/lib If you are running 64-bit applications, you would use: export LD_LIBRARY_PATH=/usr/lib64:/opt/ibm/sna/lib64 export LD_RUN_PATH=/usr/lib64:/opt/ibm/sna/lib64 For Java CPI-C applications you should also set the environment variable: export CLASSPATH=$CLASSPATH:/opt/ibm/sna/java/cpic.jar - Configure the client/server connection parameters using an ASCII configuration file created in /etc/opt/ibm/sna/sna_clnt.net. Refer to the Quick Beginnings book for configuring Remote API Client on Linux for details on this file format. - Start IBM Remote API Client. After installation this will happen automatically when the system is rebooted. cd / sna start 2.3.1 Post-install cleanup -------------------------- When you are done with the installs, the tgz file and temporary directory created in section 2.3 may be erased. 3. Uninstallation information ----------------------------- The IBM Remote API Client packages can be removed with the following commands: /opt/ibm/sna/bin/sna stop rpm -e ibm-commserver-cli rpm -e ibm-commserver /sbin/shutdown -r now Not all of these packages will be installed on every system. The IBM Remote API Client no longer requires Streams, so you can uninstall the LiS package if no other applications require it. Uninstalling IBM Remote API Client will leave any customized configuration information behind for use by a later installation. 4. Known limitations and problems ---------------------------------- None 5. Documentation updates ------------------------- See the "WhatsNew7110.txt" file in the root of the CD for more details. 6.
