As Dave says, ADABAS has a call interface that's not too hard to navigate. In your case, perhaps a Find command (S1 I think). You have to supply a parameter list CB,FB,VB,RB,IB.

Re: zos program to supply web based client
I have a number of REXX CGI programs that I wrote originally for the Domino Go HTTP server, and subsequently migrated them to the z/OS supplied Apache HTTP server. They ran unchanged for the most part, except for early after the Apache server was made available for z/OS, CGIPARSE was not available and I had to substitute code to parse the variables by hand. Then later CGIPARSE was again made available to Apache and they were changed back (I think) to almost their original form.

Re: zos program to supply web based client
Tim Hare brings up another viable choice. Here are some pointers:
1. Yes, you can use the IBM HTTP Server for z/OS in the fashion
(request-dynamic response) Tim has in mind. One of my colleagues wrote some
REXX sample code which uses the Common Gateway Interface (CGI) support in
the Apache-based IBM HTTP Server for z/OS. That sample code and associated
documentation is available here:
http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/TD106087
As another example, Steve Comstock (who posts here from time to time) sells
some "how to" manuals showing how to write CGI programs in COBOL and
Assembler:
http://www.trainersfriend.com/zOS.shtml
2. If you're even slightly more clever then you can extend the above
technique(s) to parse JSON-formatted data from the inbound request and
return JSON-formatted data to the requestor.
The base z/OS operating system includes JSON callable parsing services,
described here (z/OS 2.3 link):
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.ieac100/ieac1-cwe-json-services.htm
To generate (and/or parse) JSON you could use Enterprise COBOL ("JSON
GENERATE" was introduced in Version 6.1), CICS Transaction Server's JSON
pipeline (part of CICS Web Services), the JSON/RESTful support in MQ for
z/OS (I believe they're callable services), or Java libraries for JSON
(there are a bunch of them), as examples.
With JSON parsing/generation added you'd be partially reinventing an
excellent, much better, bidirectional, and fully IBM supported wheel (z/OS
Connect Enterprise Edition). That's probably not a terrific idea, but I
have seen one customer do exactly that for some strange reason.
3. I probably should have also mentioned that those of you with Db2 for
z/OS could use that if Db2 can answer the requests, at least via a Db2
stored procedure. Db2 supports a wide variety of client connection
protocols including DRDA, JDBC, ODBC, ADO.NET, and RESTful/JSON.
As always, be careful about security.

Re: zos program to supply web based client
I haven't seen the Apache web server mentioned for some reason.

When I fooled with it I chose to return XML but you can return whatever the client program needs I am sure. I don't know if Apache still support CGI but it definitely supports _some_ way to invoke an application program via the web. The Apache server is "free" with z/OS, too, I believe.

In the IBM product portfolio, z/OS Connect Enterprise Edition or, if direct to ADABAS, Data Virtualization Manager for z/OS would likely be the preferred, elegant approaches. However, if you want to cobble something together without too much effort as a "one off," and with something your customer already has licensed, I would look at the z/OS Management Facility and its REST interface for jobs. Details are available here (z/OS 2.3 information): https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.izua700/IZUHPINFO_API_RESTJOBS.htm The Windows Server would submit a z/OS job using this REST interface, and that z/OS job would then execute whatever program logic and ADABAS database update(s) are required, then return the result (the schedule slot). Probably what you'd do is use the z/OSMF REST interface to submit a job (and have the client check to make sure the HTTP return code is one of the return codes that indicates z/OS received the request), then use the z/OS Client Web Enablement Toolkit so that z/OS can return the result to the Windows Server (and can invoke a REST interface on the Windows Server available for that purpose). I've seen people suggest FTP and ssh paths, and they involve the same basic principle (submit a job, get a result), but I think those paths are less future proof and would involve some more work for error handling. I also have greater security concerns with those paths and think the necessary work to make these REST interfaces secure would be less onerous. Sockets are rather hard. There are hacky ways for z/OS to take action after another system places a file on a network drive (NFS) shared between that system and z/OS, but I don't like idea at least in this case. The Windows Server could have a 3270 emulator installed, such as IBM Personal Communications, which runs a macro that then makes its request and receives its response over an encrypted TN3270E connection to the "normal" 3270 application for getting a schedule slot. That's not my favorite path either. Another possible approach is to use Software AG's HTTP Server that's embedded in its Com-plete transaction processor. It's pretty basic, but it does support CGI. (I suspect Software AG was inspired by CICS Web Support.) I don't think Com-plete's HTTP Server supports HTTPS on its own, but fortunately you can (and should) use z/OS's AT-TLS to solve that problem. Here's some information on how you would set up AT-TLS with CICS Transaction Server if CICS is using HTTP (not HTTPS): https://www.ibm.com/support/knowledgecenter/en/SSGMCP_5.5.0/security/web/dfht3_attls.html The AT-TLS setup with Com-plete's HTTP Server should be quite similar. Alternatively, you could set up an IPSec tunnel between the Windows machine and z/OS. One problem with a Com-plete-based approach is that it won't work for your other customers that don't have Com-plete. It also wasn't inherently designed for application-to-application integration (as REST interfaces are), although it can be used that way in a pinch. I would think about how to avoid "double booking" and other such issues. Do they need transaction scope across both systems?

I was hoping that the web enablement toolkit would fit, but it travels the wrong direction (can get data from the outside to the mainframe), when they need to get the data from the mainframe to the open systems server.

But I had been informed that the Web enablement toolkit is for z/OS applications to act as clients, meaning that they are the ones asking for data, this application needs to work the other way around witht he mainframe application supplying the data to the outside.

Re: zos program to supply web based client
Hi, The z/OS Web Enablement Toolkit does not work under CICS. So it can possible be invoked by all sorts of languages but won't work in every 'environment'. And I would think that CICS is one of the most important 'environments' where an application could run. It can be invoked in a batch job or IMS transaction.

Re: zos program to supply web based client
Hi, You can implement this with relative ease in CICS transactions that use CICS WEB statements. CICS has extensive builtin support for these kind op applications. We are implementing restful APIs that way. Regardz, Fred! > I have a "how can I do that" type of question.

Re: zos program to supply web based client
Brian, do you have any more information about the program that's going to be involved in answering this query, such as programming language and run-time environment (CICS Transaction Server, for example)? The "best" answer may vary a little depending on those high-level details. Besides z/OS base and ADABAS (base license anyway), what other major software products do they currently have on z/OS, if any?

Re: zos program to supply web based client
Probably not what you want, but the first thing I think of is ssh. I've
written web applications running php on Linux/Windows that do things
like this (if I remember correctly):
exec("ssh use...@mainframe.ip some_script.sh",$out,$rc);
SSH keys need to be setup on the running system, but that's not
difficult. Then the script can run, do what it needs to grab the small
amount of data, and echo it back. This is from the server side of the
web application though - maybe you're looking for something on the
browser javascript side.

I know that IBM added the web enablement toolkit to provide the ability for applications
under z/OS to access data that might be on some web server out in the net to get
information or data, but is there a built-in way to do this in the other direction,
getting the data from the mainframe directly back to the web based application? For
instance, if I'm running in a web application under windows and I need to know if some
specific item was updated on z/OS and what it was updated to, is there a method or API
that I can use to "ask" the mainframe to run a program that will do the check
for me dynamically and pass me back the solution?
The reason I ask is that we have a user group that moved "off" the mainframe
but they want to be able to get a date and time from a file that is still on the
mainframe. That file is updated periodically within a completely unrelated mainframe
application. The entire file is huge (it's actually within an Adabas file) and they just
want the two fields from one record, which needs to be processed by a specific program on
the mainframe the would read the file, do the computations on the record and then pass
the solution (which is basically just a date and time) back to the windows server that
the user is now running on who needs that piece of information.
What would be the simplest or best way to accomplish that?
Thanks for your help ahead of time.
