I think you have to see how many mainframe CICS environments have adopted
the WEBifying processes in CICS, let along PHP for CICS.  I am a strong
proponent for putting web services in Mainframe applications.  However, I
would like to see more vetting of the ported tools to ensure a
non-disruptive environment.  Can a DoS attach occur?  Can the mainframe stop
it?  How to I restrict services when needed?  

It is also true that we have z/OS USS processes in the z/OS environment.  We
can run many ported tools.  But again, look at how many shops have adopted
it.  Vendors like CA have incorporated JBOS into their MSM product for
mainframe maintenance for CA software products.  They originally used TOMCAT
but now I think it is JBOS.  We also have HTTP functions and well as others.
We only install what has been vetted.  Other products, we take a wait and
see attitude.

They are still in the minority.

And unlike an open systems environment, we cannot buy a mainframe computer
or carve out a new LPAR to just RUN a CICS environment that supports web and
mobile applications.  That is fiscally prohibitive.  Though I am sure some
shops that are HUGE, might have the dollars to do that.  However small and
medium shop have to be much more conservative.

And I think that is the biggest difference between open systems and
mainframe.  We can multi-task huge applications and data on one LPAR or
SYSPLEX.  Whereas I believe in open systems, they just keep adding servers
or VM Ware to handle the workload.


Now, it is not for the lack of trying by some of us grey-beards.  But the
consideration for SLAs, outage impacts, up time, resource utilization, and
performance aspects, must give us pause.  I am now and always will be more
concerned about system impacts than I will with how much a ported tool could
make my life easier.

Whenever I develop in-house an ISPF application for restricted usage, I get
a ton of emails when it "does not work".  So I have seen the pain of a
limited usage process and not production.  

The last aspect I have not discussed is Change Control.  The mainframe
cannot always just add tools in, without a change control approval.  That is
why if it is under my TSO ID, I am good.  If it is shared, there is change
control.  We really do need to know what is in use and where.  Even my
production batch JCL has to go through Change Control and a Change
Management Software (like Changeman or Endevor).  If I want to bring in
something for a Proof of Concept, I have to go through Hoops.



Again, my two cents worth

But CICS is now touting PHP for CICS applications for mobile devices. 
That's open source software.
To keep up with the Jones the mainframe has to adapt. If a vendor like
Rocket offer support for the open source software that's all well and good.
But that's still vendor lock in isn't it?
