Installation Issues
===================
Java Runtime Environment
------------------------
The Java Runtime Environment is required to run the GUI configuration
tool (ctgcfg). Version 1.1.7 is recommended. Note, JDK 1.2.2 is supported,
but not Java 3.

If this product has been supplied on CD the Java Runtime Environment is
included. It can be found in the directory JRE/Solaris with
the filename Solaris_JRE_1.1.7_08_sparc_ibm.tar. To install:
1. Use the command: tar -xvf Solaris_JRE_1.1.7_08_sparc_ibm.tar
2. Move the Solaris_JRE_1.1.7_08_sparc_ibm directory to your target
   directory.
3. Add to your path the bin directory contained beneath the target
   directory.

Adobe Acrobat Reader
--------------------
If this product has been supplied on CD the English Adobe Acrobat Reader
is included. It can be found in the directory Acrobat/Solaris with the
filename aix-rs-40_tar.gz. To install:
1. Run the command: gunzip sunsparc-rs-40_tar.gz
2. Run the command: tar -xvf SSOLRS.tar
3. Change to the directory SSOLRS.install
4. Follow the instructions in the file INSTGUID.TXT

It is recommended that the Acrobat Reader is installed into the default
location.


CICSTERM Behaviour and Signon Capable Terminals
===============================================
CICSTERM now attempts to install a signon capable terminal by default.

Use the option '-a' to request the default CICSTERM behaviour as in
releases prior to v3.1.0.

CICS Servers require APAR fixes to support the terminal signon capability
function available in this release:

  CICS/ESA 4.1             PQ30167
  CICS TS v1.2 and v 1.3   PQ30168
  CICS/VSE 2.3             PQ30169
  CICS/VSE TS v1.1         PQ30170
  TX Series                IY03691

CICS TS v1.3 Servers
--------------------
If the server does not have the required APAR applied and the '-a' option
is not specified on CICSTERM, the installed terminal will give unpredictable
results.

TX Series Servers
-----------------
If the server does not have the required APAR applied and the '-a' option
is not specified on CICSTERM, the Client will display the message:
   'CCL7053E Errors found while communicating with server'
and the message:
    CCL3105 Inbound CICS datastream error (CTIN, 4, 0)
will be written to CICSCLI.LOG.

On the server, the message:
   'ERZ042004E/0112: An invalid request was received from client'
will be written to CSMT.out and console.msg will include:
   'ERZ014016E/0036: Transaction CTIN Abend A42B'.

Security on OS/390 Servers
--------------------------
Security checking done in the server for transactions started at a signon
capable terminal installed by a Client application does not depend on what is
specified by the ATTACHSEC option for the connection representing the Client.
Instead security checking depends on whether the user signs on while using the
terminal.

If the user does not sign on, the Client installed terminal is associated with
the default user defined for the server in the SIT. When a transaction is run,
the security checks are carried out against this default user. A check is also
done against the userid associated with the connection to see whether
the Client itself has authority to access the resource.

When a user does sign on, the terminal is associated with the userid just
authenticated. For transactions attempting to access resources, security
checking is done against the userid associated with the connection and the
signed-on user's userid.

It is recommended that the Usedfltuser parameter on the server connection
definition is set to Yes if using signon capable terminals and to No if using
signon incapable terminals.


EPI Purge Terminal Restriction
==============================
The EPI purge terminal function will not cancel ATI requests queued
against the terminal. This is a temporary restriction in this release.


XTERM and function keys
=======================
When running in an XTERM window, cicsterm may not recognise all function
keys. This is because of the terminal type. If you are having problems
with cicsterm recognising functions, either run cicsterm in a different
window or set the TERM environment variable to a different terminal type
such as vt100 (by default, this environment variable is often set to
xtterm).


Running the CICS client over telnet
===================================
If you run the CICS client over telnet, you may find that certain telnet
clients cause problems with the display. For example, your telnet session
may truncate message lines which are over a certain length. This is usually
a problem with the telnet client that you are using, or the terminal type
that you are going in as.


Using X-Windows clients
=======================
You may find that some X-Windows clients (such as Exceed) corrupt the text on
the title bar of the window that you are trying to display. For example,
this might happen with the Configuration Tool. This is usually a problem
with the X-Windows client that you are using.


Timeout processing on TCP/IP protocol
=====================================
Client timeout processing will only result in server cleanup processing
on a server linked via the TCP/IP protocol, if the server has support
for this function installed.


DBCS Support in the COM and C++ Libraries
=========================================
The COM and C++ libraries do not provide any specific support for 3270
datastreams that contain DBCS fields.


Update to Client/Server Programming Book
========================================
Additional return code on CICS_EpiTerminate:
   CICS_EPI_ERR_TTI_ACTIVE
       A transaction started from the EPI is still active or a
       CICS_EpiGetEvent call is still outstanding.


Updates to C++ and COM Automation programming books
===================================================

Disconnect Documentation
------------------------
There is a mistake in the CclTerminal Reference section, specifically in the
definition of disconnect. It should read as follows :-

disconnect (1)

     void disconnect()

     Disconnects the terminal from CICS. No attempt is made to purge any
     outstanding running transaction.

disconnect (2)

     void disconnect(Ccl::Bool withPurge)

     withPurge
           Ccl::Yes  -  Disconnects the terminal from CICS and will attempt
                        to purge any outstanding running transaction

           Ccl::No    - Disconnects the terminal from CICS. No attempt is
                        made to purge any outstanding running transaction.

In the COM Automation programming book the definitions of disconnect and
disconnectwithpurge are the same, this is not correct it should be

Disconnect
   Disconnects the terminal from CICS. No attempt is made to purge any
   outstanding running transaction.

DisconnectWithPurge
   Disconnects the terminal from CICS and will attempt to purge any
   outstanding running transaction

exObject method in CclException Class
-------------------------------------
This method is relevent to both ECI AND EPI.
exObject now will return the relevent CclTerminal object pointer in the
exception block for EPI applications. It will need to be cast to a CclTerminal*.
For example:
CclTerminal* pTerm = (CclFlow*)ex.exObject();


SNA driver requirements
=======================
Automatic Transaction Initiation (ATI) is not available.

Patches required for the Solaris SNA support
--------------------------------------------
SNA is supported on the Solaris client through the Sunlink 9.1 product.
It is recommended that the latest set of patches are applied to the Sunlink 
product before using it with the CICS Client.

At the time of testing, patches 105860, 106162, 106164, 106165 and 106723
were required as these provide a new reentrant version of the Lu6.2
library (liblu62_r.so) which is required.


Using C++ version 5
===================
Two versions of the C++ Client library are provided.
The library libcclcp.so is provided for Solaris C++ version 4.2.
Due to changes in the Solaris C++ version 5 linking, a new Client
library libcclcp5.so is provided for linking with version 5 applications.

Additionally, patch 107311-09 (and its prerequisite patch 107357-05) must 
be applied  to the compiler to prevent hangs which were encountered during
testing, especially when tracing is active. 


Compiling C++ applications that use the C++ libraries
=====================================================
If you are compiling C++ applications which use the CICS C++ libraries
then you need to define the CICS_SOL macro instead of using CC_UNIX.
CC_UNIX will still work in this release but may be removed in a future release.

Service and Updates
===================
Service and updates will be made available via the Internet.
See:
   http://www.software.ibm.com/ts/cics/support/details

Service process for JREs on Solaris
-----------------------------------
The JRE packaged with the CICS Transaction Gateway and CICS Universal Client
for the Solaris platform is supported by Sun Microsystems, Inc.
Customers using this JRE can keep up to date with Sun upgrades by accessing
the Sun Web site below and installing fixes/JRE refreshes as they become
available from Sun.
