2.  Installation information
----------------------------

The CS Linux 6.2.0.1 Client is is shipped as a compressed tar
file (tgz).  The tgz file contains the RPMS, install shell
scripts, and licensing tool.  You will need an FTP server or
other method of transfering files into the Linux system.


2.1  Hardware requirements
--------------------------

CS Linux requires a Pentium II or later 32-bit Intel system
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 'i686' to indicate a Pentium II or later system.


2.2  Software requirements
--------------------------

2.2.1  Linux operating system version
-------------------------------------

This version of CS Linux has been tested with the following
Linux operating system versions.  It may also run satisfactorily
on other Linux distributions.

  RedHat Enterprise Linux 2.1
  RedHat Enterprise Linux 3
  SuSE Linux Enterprise Server 8 (SLES8)
  SuSE Linux Enterprise Server 9 (SLES9)


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)".  Use the
"rpm -q -a" command to see what packages are currently installed.


  RedHat Advanced Server 2.1
  --------------------------
    Required:
      XFree86-libs-4.1.0-25
    Optional, needed for JavaCPI-C:

    Required:
      XFree86-libs-4.1.0-44
    Optional, needed for JavaCPI-C:

  RedHat Enterprise Linux 3
  -------------------------
    Required:
      XFree86-libs-4.3.0-35.EL
      rpm-4.2.1-4.4      (from http://rhn.redhat.com/errata/RHEA-2004-010.html)
    Optional, needed for JavaCPI-C:
      IBMJava2-SDK-1.4.1-9


  SuSE Linux Enterprise Server 8 (SLES 8)
  ---------------------------------------
    Required:
      binutils-2.12.90.0.15-50
      xshared-4.2.0-188
    Optional, needed for JavaCPI-C:
      IBMJava2-SDK-1.3.1-24

      glibc-2.3.3-98.28
      XFree86-libs-4.3.99.902-43.22
    Optional, needed for JavaCPI-C:
      IBMJava2-SDK-1.4.2-1           (download)



2.2.4 Java
----------

A Java may be needed for CS Linux if you use the JavaCPI-C API.
Using the latest Java 1.4.2 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 IBMJava2-SDK-1.4.2-1.0.i386.rpm

For RedHat Enterprise Linux 3, use the IBMJava2-SDK-1.4.1-9 RPM
from the RedHat Enterprise Linux 3 install CDs.

For RedHat Enterprise Linux 3
which uses the 2.4.20 or later kernels,
you might also have to run:
    export LD_ASSUME_KERNEL=2.4.1
in order to use the current Java RPMs with those Linux distributions.



2.3 Installation process
------------------------

If you have a previous level of CS Linux already installed, follow
the steps in section 3 to remove it before installing this new level.

To install the CS Linux 6.2.0.1 client follow these instructions.

-  Download the 6.2.0.1 Linux intel client PTF tgz package from:

       ftp://ps.software.ibm.com/ps/products/cslinux/fixes/v6201

   then uncompress and un-tar it:

       mkdir /tmp/ibmcs
       cd /tmp/ibmcs
       tar -xzf ibm-commserver-client-6.2.0.1.i386.tgz

-  Run the installibmcscli shell script

       ./installibmcscli

   The installibmcscli shell script will test for certain
   pre-requisites 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 CS Linux 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

   For Java CPI-C applications you should
   also set the environment variable:

       export CLASSPATH=$CLASSPATH:/opt/ibm/sna/java/cpic.jar


-  Start CS Linux.  After installation this will
   happen automatically when the machine is rebooted.
   Make sure you are not still in the
   CD's directories when this is done.

       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 CS Linux packages can be removed with the following commands:

    /opt/ibm/sna/bin/sna stop
    rpm -e ibm-commserver-ptf
    rpm -e ibm-commserver-docs
    rpm -e ibm-commserver-ecl
    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 CS Linux Client no longer requires Streams, so you can uninstall
the LiS package if no other applications require it.




4.  Known limitations and problems
----------------------------------

4.1 Number of concurrent LUA+APPC+CPI-C+NOF applications
--------------------------------------------------------

The maximum number of concurrent LUA+APPC+CPI-C+NOF applications
using the CS Linux Client is 240.

If this limit is reached, the following message will be logged
in /var/opt/ibm/sna/sna.err:
  hh:mm:ss TZ dd mmm yyyy 16392-13(33-0) E (hostname) PID pid# (application)
  Failed to allocate an IPC control block.


4.3 Using applications and TPs built on older levels
----------------------------------------------------

There is one issue when trying to use applications and TPs that
were compiled on older levels of Linux, CS Linux and LiS.

Some new distributions are based on a Linux kernel
level (2.4.20 or later) which includes a new threading model.
You may have to recompile your applications on these
distributions for them to work properly or you may be
able to set the environment variable:
   export LD_ASSUME_KERNEL=2.4.1
to force the old threading model.




5.  Documentation updates
-------------------------

The CS Linux Client no longer requires Streams, so the
references in Quick Beginnings to Streams and LiS do not apply
to the Client.
