WWW and Application Server
The DragonFly Server provides many of the same capabilities found in
non-mainframe offerings (CGI, Dynamic HTML).
In addition to standard CGI functionality, DragonFly
can be enabled to submit mainframe batch, communicate with operations,
bind with DB2, issue TSO commands, benchmark IP Network paths,
set conditions to commence or halt job scheduler functions etc.
Multiple servers run in their own address space, can have their own
security definitions, resources and databases. This provides the
capability of secure and isolated servers coexisting with open
servers. In addition, multiple instances allow the type of
development/testing/acceptance/production standard in
MainFrame processing environments.
One of the MainFrames many strengths is the ability to share
databases and files for inquiry/update. These standard
facilities are supported by the DragonFly server.
Beyond CGI stdin/stdout
Previous CGI standards allowed communication using stdin/stdout
between the server and application. DragonFly uses parameter passing
through memory pointers for faster non-I/O transfer of data.
The DragonFly Server includes the ability to respond with different
text or entirely different documents based on the client post request
through the CGI interface.
Dynamically generated documents may also contain Java Scripts.
HTML Conversion Utility
HTML presented by this server version is either generated by the CGI
interface or retrieved from a VSAM database for performance. The
convert utility is provided to place HTML source into this VSAM
database or to retrieve existing VSAM format HTML. All HTML editing
can be done using the standard ISPF interface or your most
sophisticated Web editing suite.
Browser for capture
A Browser type utility is provided to capture HTML source and images
from the internet. This captured data may be stored in the DragonFly
database or passed on to job streams. This will allow WEB event
initiated MainFrame actions. The WEB server queried may be IP
addressable or name addressable.
This feature allows
a shadow instance of the Server to be running on a second MainFrame
that shares DB2/DASD (disk). The second server will carry on in the
event of an outage or scheduled shutdown of the first MainFrame.
This feature must be synchronized with specification of
a secondary server/IP in the DNS.
MainFrame Programming Languages
Most standard IBM languages are supported. Full CGI functionality is
available with PL/1, C and Assembler. Language Environment is the
default. Full database functionality is available with COBOL.
For other language support, please call us.
Warning: It is not advised to post sensitive information on a system
on which untrusted users have access.
This Server is shutdown remotely, by the
DragonFly browser utility or by a console command.
All error messages can be found in the
messages section of this documentation.
Version 1.4 of the DragonFly server is
not limited to 32K object sizes. The default limit shipped with
the sever is 3.2 MegaBytes and can be extended to whatever region size
your system supports. The browser has an object size limitation of
approximately 4 GB. The Browser in this release supports virtual domain
names and does not require you to obtain the IP address of a site.
