This readme file contains important information about the IBM CICS Transaction Gateway (CICS TG) that might not be available in the Eclipse Information Center.
The product documentation is provided as an Eclipse Information Center available at:
http://publib.boulder.ibm.com/infocenter/cicstgmp/v7r2/index.jsp
This readme file is available in plain text and HTML. Both files contain the same information. After installation the files are included in the <CICS TG install path> directory.
The text version of this file is suitable for use with a screen reader or braille device.
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.
It is recommended that 240 MB of temporary storage is available to successfully complete installation.
Before running the CICS TG installer it is strongly recommended that you shut down all programs running on your system.
Install can be run in GUI, console or unattended mode The default mode is GUI.
GUI mode installation can be launched using the following command:
installer
Console mode installation can be launched using the following command:
installer -i console
Unattended installations can be launched using the following command:
installer -i silent -DLICENSE_ACCEPTED=true
Using the unattended installation can result in the machine restarting without warning.
Use the command:
ctguninst
By default the CICS TG uninstall command matches the mode used at installation. You can override the default mode to run in GUI, console or unattended mode.
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 -i swing
Console mode uninstall can be launched using the following command:
ctguninst -i console
Unattended uninstall can be launched using the following command:
ctguninst -i silent
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.
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 -?
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.
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.
The supplied version of Java is IBM 32-bit Runtime Environment for Windows, Java 2 Technology Edition, Version 5 Service Release 7.
After installing CICS TG to a new system, open a new command prompt and run the ctgjava command to specify which Java Runtime Environment is to be used with CICS TG. For example:
ctgjava -s="C:\Program Files\IBM\CICS Transaction Gateway\jvm15\bin\java.exe"
The CICS TG does not run as a Windows service on Vista. For further information refer to the Information Center.
To open a configuration file with an extension of 'ini' using the configuration tool you must set the filter to 'All Files' in the open file dialog.
IPIC is supported to CICS TS version 3.2 regions with the following APARS applied :-
When configuring an IPCONN definition in CICS TS for communication with CICS TG, the SENDCOUNT parameter must be set to zero.
IPIC is supported to TXSeries version 7.1 regions with Fix Pack 1 applied.
Outside a J2EE environment, you must ensure that the following Java extensions are available:
* JAAS (required for EPI resource adapter). * JCA 1.5 Connector class file (required for ECI resource adapter) * Java Transaction API (required for XA transactions)
Note: JAAS is included with IBM JREs and JDKs by default. The JCA 1.5 Connector class file and the Java Transaction API (JTA) libraries are available for download from the Sun Java Web site.
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'.
When the installer or uninstaller program is cancelled on Windows Vista the 'Program Compatibility Assistant' starts. Select 'The program installed correctly' to cancel the assistant.
The progress bar does not accurately reflect the installation progress.
When installing or uninstalling you need to use uppercase parameters to control the mode. For example:
installer -i SILENT -DLICENSE_ACCEPTED=true
Read this if you are running CICS TG as a Windows service and need to change the default port for local administration (adminport).
The CICS TG default adminport is 2810. You might need to change this if this port is used by another application. However, running CICS TG as a service on Windows with a non-default adminport, can cause the service to become unresponsive during shutdown. To avoid this problem, before starting the service issue the command:
ctgservice -R -A-adminport=<new port number>
This updates the CICS TG service registry entry with the new port number. Starting and stopping the service will then use the new port number.
Below is a list of APARs included in this version of the CICS Transaction Gateway. Full details can be found on the support pages: http://www-306.ibm.com/software/htp/cics/ctg/support/
