IBM CICS Transaction Gateway Version 7.1.0.5 - README for AIX

IBM CICS Transaction Gateway Version 7.1.0.5 - README for AIX

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 CICSPRNT AND CICSTERM COMMAND OPTIONS

CICSPRNT OPTION TO PRINT BLANK LINES

A new -b option is available on the cicsprnt command. By default, cicsprnt does not print blank lines. A blank line is defined as a line that contains only null characters or non-displayable fields, or is undefined in the BMS map. This option causes blank lines in the data stream to be printed, for example enter the command:

cicsprnt -b

CICSTERM SUPPORT FOR ADDITIONAL DEFAULT COLORS

A new -e option is available on the cicsterm command. The -e option specifies that when extended attributes are included in a 3270 datastream received by cicsterm and no color attribute is set, the color of a field is determined by both the intensity and protection attributes. The colors used to display the field are then determined by the normal_unprotected, intensified_unprotected, normal_protected and intensified_protected definitions in the color mapping file. By default, when this option is not specified, the 3270 datastream contains extended attributes and no color attribute is set, the color of fields is determined by the default and default_highlight definitions in the color mapping file. Example command useage:

cicsterm -e

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 runs in console mode and must be run by a user with root privileges. Before installing or uninstalling the Fix Pack shut down any local CICS TG applications, the Gateway daemon and then the Client daemon.

After the Client daemon has shut down issue the command:

/usr/sbin/slibclean

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 code_set

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 SMITTY remains as the original installed version.

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 '-'.

SUPPORT FOR IPIC CONNECTIONS

IPIC connections can be used with all in-support versions of CICS TS and TXSeries which have IPIC capability. All relevant IPIC maintenance must be applied to your CICS TS or TXSeries server.

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'.
