New SILK Web Facilities for MVS Data Set Listing and Job Submission
How Do I Get Listings of Data Sets via the Web?
Do you need a listing—but aren’t logged onto WYLBUR or TSO? Simply grab your web browser and go to
http://silk.nih.gov/listoff/.
A web form appears that enables you to specify a data set name and select offline listing options—including box number, remote printer number, DISCOUNT, HOLD, IMPACT, PUNCH, and SCRATCH (if you wish to scratch the data set after it is listed).
Once you have completed the form, just click on the "Submit" button. The job number of the batch job submitted to create the listing will be displayed.
With SILK Web’s Listoff you may list the data sets that your initials (specified in the account/initials field of the browser security window) have authority to read. Any non-VSAM data set—except those in WYLBUR edit format—may be listed offline. The submitted job is run with the RACFid of the initials specified. The listing will appear in the specified output box or remote.
What About Submitting Batch Jobs from the Web?
To try SILK Web’s "Submit" facility just go to http://silk.nih.gov/submit/. When the web form appears, merely enter a data set name to be submitted as a batch job and specify options—including remote print routing, impact printing, DISCOUNT, HOLD, NOTIFY, as well as BEFORE, AFTER or CNTL.
What the system supplies
- If the job name of the submitted job begins with the initials specified (in the account/initials field of the web browser security window), then the appropriate keyword will be inserted.
- If the RACFid in the job statement (USER=racfid) is the same as the specified initials, then the proper password will be supplied.
What you may need to supply
- If the job name begins with different initials, then you must supply the keyword in the web "Submit" form, or have a /*KEYWORD statement in the data set being submitted.
- If the RACFid in the job statement (USER=racfid) is not the same as the specified initials, then you must supply the password on the web form or have a /*PASSWORD statement in the data set being submitted
The data set being submitted via SILK Web’s "Submit" button must be FB with LRECL=80. Please note: the data set can not be WYLBUR edit format. If the data set is RACF protected, the initials specified in the browser security window must have authority at least to "read" that data set. After you click on the "Submit" button, the data set will be submitted and the job number will be displayed.
If the job was rejected for some reason, that information will also be displayed. To find why the job was rejected, you must look at the printed output or fetch the job through WYLBUR or TSO.
What Has Been Already been Woven from SILK
The SILK (Secure Internet-LinKed) Web technology permits virtually all data stored on the MVS enterprise system to be made accessible through the web—with RACF protection. SILK also provides easy ways to create and maintain web servers or pages and build web-based client/server applications. In the eight months since the Computing Facilities Branch introduced the innovative SILK Web technology, web interfaces have already been implemented for several large, enterprise databases and are providing agencies with uncomplicated, powerful access to critical enterprise applications. Over 58 SILK Web servers have already been created. Several of the public servers are:
Servers are being added regularly. See the SILK Web registry at http://silk.nih.gov/ for a list of available public servers. SILK Web technology has been described in recent INTERFACE articles—see issues dated December (No. 198), March (No. 200) and June (No. 201). Please call TASC for additional information on the SILK Web facility.
SILK Web’s New "Easymail" Facility—
A Quick Way to Send E-Mail
You are "surfing the web" and want to send e-mail, but can’t because you don’t have a Post Office server account as required by the browser’s Mailto: facility. What do you do?
If you have a registered DCRT account, initials, and password then you can:
- go to http://silk.nih.gov/easymail
- specify one or more addresses in the To: and CC: fields—just separate multiple addresses with blanks—plus a Subject: and Reply-to: address if you wish
- enter text in the box
- click on the "Send" button. You will get a message that the e-mail has been transmitted.
Easymail is a secure web address, so the person sending the e-mail will be prompted for a userid—specify your DCRT account/initials—and password.
The From: e-mail address will be "iii@cu.nih.gov" where iii are the initials specified in the userid (DCRT account/initials) field of the browser’s security box.
Link to Easymail from Any Webpage
Webpage developers can add e-mail to their pages using a hypertext link to Easymail.
- To invoke Easymail from a web page, the html for the link would be something like:
<a href=http://silk.nih.gov/easymail>
Send E-Mail</a>Clicking on the "Send E-Mail" link would display the Easymail form.
- You can also have e-mail sent to a pre-specified e-mail address—just include ?to= in the href. For example, if you wanted to send to the "webmaster@my.site.gov" address, the href would be as follows:
<a href=http://silk.nih.gov/easymail?to=webmaster@my.site.gov>
Send e-mail to Web Master</a>In this case, the Easymail form would be initialized with "webmaster@my.site.gov" as the To: address.
Set a browser bookmark to http://silk.nih.gov/easymail to provide yourself with a simple, quick way to send e-mail.
