This version of Apache includes changes allowing it to run
on IBM's EBCDIC-based TPF
(Transaction Processing Facility) operating system.
Unless otherwise noted TPF version 4.1 PUT09 is
required.
Refer to install-tpf.html for step-by-step installation instructions.
This port builds upon the EBCDIC
changes previously made to Apache.

The following is a very simple example of a CGI script
("Hello World") and the necessary steps to run it.
Refer to the mod_cgi
module for additional information.
For this example QZZ1 is the name of the TPF
program that will be executed by the CGI script.
The directory path must match what is in the httpd.conf file
for ScriptAlias directive.
/** QZZ1-- simple "Hello world" program to demonstrate
basic CGI output **/
#include <stdio.h>
void main() {
/** Print the CGI response header, required for all
HTML output. **/
/** Note the extra \n, to send the blank line. **/
printf("Content-type: text/html\n\n");
/** Print the HTML response page to stdout. **/
printf("<html>\n");
printf("<head><title> CGI Output
</title></head>\n");
printf("<body>\n");
printf("<h1> Hello world </h1> \n");
printf("</body>\n");
printf("</html>\n");
}
Apache can be invoked with various options, such as "-f". Some of these options display information about the server or perform syntax checks but they don't actually start the server. These "information only" options are useful with TPF's ZFILE command line feature: -h, -l, -L, -S, -t, -T, -v, and -V.
Another option, -X, is used when actually running the server. It is passed to Apache through the ZINET XPARM field since ZINET is the only way to start the server on TPF.
A third group of options apply to both the informational displays (ZFILE) and running the server (ZINET XPARM): -d, -D and -f.
The rest of Apache's options are either not applicable or are not supported on TPF.
Using dash options requires PJ27277 which shipped on PUT13.
| Option | ZFILE | ZINET | Description |
| -d path | ZFILE | ZINET | Set the initial value for the ServerRoot directive. |
| -D define | ZFILE | ZINET | Set a configuration parameter which can be used with <IfDefine>...</IfDefine> sections in the configuration file to conditionally skip or process commands. |
| -f filename | ZFILE | ZINET | Use an alternate configuration file instead of the default conf/httpd.conf file. |
| -h | ZFILE | List a short summary of available command line options then exit. Note that this outputs all options, not just those supported on TPF. | |
| -l | ZFILE | List modules compiled into the server then exit. | |
| -L | ZFILE | List available configuration directives then exit. Note that this outputs all configuration directives, not just those supported on TPF. | |
| -S | ZFILE | Show the settings as parsed from the configuration file then exit. Currently Apache only shows the virtual host settings. | |
| -t | ZFILE | Run syntax tests for configuration files with document root checks then exit. | |
| -T | ZFILE | Run syntax tests for configuration files without document root checks then exit. | |
| -v | ZFILE | Show the version number then exit. | |
| -V | ZFILE | Show the version number and various compile settings then exit. | |
| -X | ZINET | Run in single-process mode for internal debugging purposes only. The parent process does not fork any children. |
See http://httpd.apache.org/docs/programs/httpd.html for more information about these command line options.
Ensure Apache (CHTA) is loaded
Create the httpd script:
Mark the script as executable:
(See "ZFILE-Activate a TPF Segment or Script" in the Operations guide for more information: http://www.ibm.com/tpf/pubs/tpfpubs.htm.)
zfile httpd -v
FILE0001I 11.43.09 START OF DISPLAY FROM httpd
-v
Server version: Apache/1.3.20 (TPF)
Server built: May 23 2001 09:39:22
END OF DISPLAY
zfile httpd -t -f /usr/local/apache/conf/alt.conf
FILE0002I 11.47.26 START OF ERROR DISPLAY FROM httpd
-t ...
Syntax OK
END OF DISPLAY
(See "ZINET ADD-Add an Internet Server Application Entry" and "ZINET ALTER-Change an Internet Server Application Entry" in the Operations guide for more information about using the XPARM field: http://www.ibm.com/tpf/pubs/tpfpubs.htm.)
The syslog daemon is a server process that provides a message logging facility for application and system processes. It can be used to write messages to log files or to tapes. See TPF Transmission Control Protocol/Internet Protocol for detailed information about using the syslog daemon on TPF: http://www.ibm.com/tpf/pubs/tpfpubs.htm. And see the Apache ErrorLog directive documentation for details on how to use syslog with Apache.
Syslog capabilities were added with PJ27214 which shipped with PUT13. You must follow the syslog specific installation instructions in order to have the option of using syslog with Apache.
This section provides some tips on using syslog with Apache. It is not meant to replace the syslog documentation in the TPF TCP/IP publication.
| The syslog daemon will not create files. If you are logging to a file (as specified in the syslog.conf configuration file) that file must already exist and have permissions that allow the syslog daemon to write to it. |
| You must restart the syslog daemon for it to recognize changes to its syslog.conf configuration file. |
| The syslog daemon must be active prior to starting Apache. |
| To indicate you want to use syslog with your Apache error log add the following directive to your httpd.conf file: "ErrorLog syslog:facility" where facility is "local0" through "local7". |
| Apache will default the facility to "local7" if you omit the facility name from the ErrorLog directive (that is "ErrorLog syslog"). |
| The syslog facility name must be one that is recognized by both Apache and the syslog.h header file. The facility names "local0" through "local7" are explicitly set aside for your use. |
| Although "local0" through "local7" are recommended user facility names, here is the complete list of names recognized by both Apache and TPF's syslog.h: auth, cron, daemon, kern, local0, local1, local2, local3, local4, local5, local6, local7, lpr, mail, news, syslog, user, and uucp. |
| You won't see the normal Apache startup/shutdown messages when you use syslog with your Apache error log. |
| Syslog does not support TCP/IP Offload devices (ZCLAW) |
| Signals: On TPF a signal that is sent to a process remains unhandled until the process explicitly requests that signals be handled using the tpf_process_signals() function. Additionally, the default action for an alarm on TPF is to take an OPR-7777 dump and exit. (On UNIX the default is the equivalent of exit() with no dump taken.) These differences necessitated a few modifications: | ||||||
