IBM CICS Transaction Gateway Version 7.1.0.4 - README for Windows

The product documentation is provided as an Eclipse Information Center available at: http://publib.boulder.ibm.com/infocenter/cicstg/v7r1m0/index.jsp

This file contains important information about the IBM CICS Transaction Gateway (CICS TG) that might not be available in the Eclipse Information Center.

This readme file is available in plain text and HTML. Both files contain the same information. After installation the files are included in the <install_path> directory.

The text version of this file is suitable for use with a screen reader or braille device.

SUMMARY OF TOPICS

NEW FEATURES

SNA support on HP-UX

Additional statistics

Interact with request monitoring exits dynamically

Remote Statistics API

Please see the product documentation for further information on these features.

INSTALLING AND UNINSTALLING THE FULL PRODUCT

This section applies to running the full product installer which either installs the product or replaces an existing version of the product.

Installation and uninstallation must be done by a user with Administrator authority and for Windows Vista, elevated authority is required.

Ensure that the Application Event Log is closed prior to installing CICS TG.

Before running the CICS TG installer it is strongly recommended that you shut down all programs running on your system.

INSTALLING THE FULL PRODUCT

To install the CICS TG launch the InstallShield wizard:

installer

To install the CICS TG in console mode launch the InstallShield wizard with the -console option:

installer -console

To install the CICS TG with no user interaction launch the InstallShield wizard with the -silent and -V licenseAccepted options:

installer -silent -V licenseAccepted=true

Further information on how to use the installer can be found in the the Eclipse Information Center. Known issues are documented in this readme file.

UNINSTALLING THE FULL PRODUCT

Use the command:

ctguninst

If uninstall is started from the Add/Remove programs panel it will run in GUI mode.

GUI mode uninstall can be launched using the following command:

ctguninst -swing

Console mode uninstall can be launched using the following command:

ctguninst -console

Unattended uninstall can be launched using the following command:

ctguninst -silent

INSTALLING AND UNINSTALLING A FIX PACK

This section applies to running the Fix Pack utility which updates an existing installation of the product.

The Fix Pack utility must be run in a command prompt window by a user with administrator privileges. Before installing or uninstalling the Fix Pack shut down any local CICS TG applications, the Gateway daemon and then the Client daemon.

It is strongly recommended that you shut down all programs running on your system before running the Fix Pack utility.

INSTALLING THE FIX PACK

Change to the directory where the Fix Pack has been unpacked and issue the following command:

ctgfix

The installer will prompt for confirmation before installing. Enter 'y' to proceed. If you do not wish to be prompted for confirmation, issue the command:

ctgfix -y

During installation, the Fix Pack utility creates a log file named <CICS TG install path>\ctgfix\ctgfix.log. The log file contains details of each file that is updated by the Fix Pack, and details of any errors. Further information about the error messages is available in text file ctgfix.hlp located where the Fix Pack has been unpacked.

If the CICS TG is using messages that are not in English, issue the ctgmsgs command to switch to your language of choice:

ctgmsgs XX

For help on the ctgmsgs command, issue the command:

ctgmsgs -?

UNINSTALLING A FIX PACK

Change to the <CICS TG install path>\ctgfix directory and issue the following command:

ctgfix -u

The Fix Pack utility will prompt for confirmation before uninstalling. Enter 'y' to proceed. If you do not wish to be prompted for confirmation, issue the command:

ctgfix -u -y

During uninstall, the Fix Pack utility appends to the ctgfix.log file. The log file contains details of each file that is restored by the Fix Pack, and details of any errors. Further information about the error messages is available in text file <CICS TG install path>\ctgfix\ctgfix.hlp.

DETERMINING THE PRODUCT VERSION

After installing the Fix Pack, determine the product version by issuing the command:

cicscli -v

Components that have not been updated by this Fix Pack will display the original version.

The version of IBM CICS Transaction Gateway displayed by Windows in the list of currently installed programs, remains as the original installed version.

INSTALLING THE JAVA RUNTIME ENVIRONMENT

The supplied version of Java is IBM 32-bit Runtime Environment for Windows, Java 2 Technology Edition, Version 5 Service Release 7.

To install the Java Runtime Environment, run the command:

ibm-java2-jre-50-win-i386.exe

During Java Runtime Environment installation, you can select to install this Java as the system default. If you choose not to install this Java as the system default, you must run the ctgjava utility to specify where the Java executable is located. Refer to "Setting the JVM" in the Information Center for more details.

LIMITED SUPPORT FOR WINDOWS VISTA

The CICS TG does not run as a Windows service on Vista. For further information refer to the Information Center.

CICS TG STATISTICS API DOCUMENTATION

Reference documentation for the statistics API is included in the information center. The documentation is also included as part of the CICS TG installation, in <install_path>/docs/ctgstatsdoc.zip. To view the documentation, expand the contents of the ZIP file into a suitable directory and view file 'index.html' with a Web browser.

CICS TG SERVER NAMES IN STATISTICS QUERIES

If the ctg.ini configuration file contains server names which have one or more underscore characters '_' in them, when the server name appears in a ctgadmin command or statistics API query, any underscore characters will have been replaced by a minus character '-'.

IP INTERCONNECTIVITY PROTOCOL (IPIC)

CICS TS v3.2 has introduced a new IP interconnectivity protocol as an alternative to that provided by ISC or MRO. Using IPIC, CICS Transaction Gateway v7.1 adds support for the Channels and Containers programming model which provides relief from the 32k commarea limit; 2-phase commit (XA) via the JCA Resource Adapter and enhanced security options. IPIC also provides request tracking facilities and SSL support in Local mode.

CICS TS SUPPORT FOR IPIC

IPIC is supported to CICS TS version 3.2 regions with the following APARS applied:

CICS TS APARS REQUIRED FOR IPIC SUPPORT

ACCESSIBILITY FEATURES

STARTING THE GATEWAY DAEMON FROM A COMMAND PROMPT USING A SCREEN READER

In some Telnet sessions, the screen reader might re-read CICS TG log output or the command prompt, after the CICS TG has started. This is expected behavior, and does not mean that the CICS TG has failed to start. To determine if the CICS TG started correctly, listen for the message:

'CTG6512I CICS Transaction Gateway initialization complete'.

If the CICS TG did not start successfully, one of the following messages is output:

'CTG8821E The CICS Transaction Gateway was unable to start the Client daemon'.
or
'CTG6513E CICS Transaction Gateway failed to initialize'.

KNOWN ISSUES DURING INSTALLATION OR UNINSTALLATION

INCORRECT PROGRESS DISPLAYED WHEN MIGRATING FROM OLDER VERSIONS

When upgrading from earlier versions of the CICS TG the installer program does not display progress correctly; ignore the progress display. The installation is unaffected by the incorrect progress display.

CANCELLING AN INSTALL OR UNINSTALL ON WINDOWS VISTA

When the installer or uninstaller program is cancelled on Windows Vista the 'Program Compatibility Assistant' will start. Select 'The program installed correctly' to cancel the assistant.
