Phil, you are doing the most evil thing possible in SMP/e and you need to spend 
time understanding the concepts to avoid damaging your product at a customer 
site. If you must use LIBRARY, then at least use it correctly for SMP/e. SMP/e 
provides multiple solution to solve this problem correctly but this is not one 
of them. We've only seen a very small snippet of your install process so it's 
difficult to say what works best in your situation.

Sysprog question: Is there any one of you that would think to update JCLIN 
every time you create a new maint environment for his product? Is your 
expectation to only modify DDDEF or are there additional consideration?

1. Stop thinking in terms of cloning because that's a zVM and zLinux concept 
where you're applying maint to a live system. In z/OS, maint is applied to 
inactive copies of products.

2. What makes you think LIBRARY /x/y/z/ in JCLIN is your only solution? 
Wouldn't LIBRARY MYLIB in JCLIN and UCLIN DDDEF MYLIB /x/y/z/ work equally as 
well while supporting standard maint philosophy?

3. I have to agree with Kurt about using INCLUDE instead of LIBRARY. Critical 
products typically specify NCAL which ignore syslib autocall, AUTOCALL and 
LIBRARY in SMP/e and binder for a reason. As you say, libsapi.a is "your" 
library that in theory you distribute using SMP/e. You should be telling SMP/e 
about the contents of that library to be consistent during your update process, 
the binder should be verifying using those same includes. SMP/e can bury 
problems that customers may not notice (e.g. NCAL rc=8).

>The book goes on to say:

This SMP/e book says many things but some things are not heavily used nor 
complete. Do you think LIBRARY doc is going to be robust like INCLUDE? I'm 
happy that you've gone 10 years without a problem but I'm a little surprised.

I guessed wrong because your libsapi.a is partially under SMP/e control and 
partially not. Common practice is to be consistent and have 1 customer change 
to redefine the location (namely DDDEF). Instead, the customer must change all 
occurrences after the product is installed.

This is definitely not a relfile. You say your customers copy & modify this 
JCLIN.

Does anyone here know of anyone using SMS instead of VOLSER to install 
products? Phil, do you have customers asking to install using SMS instead of 
VOLSER? 

It's simple to accommodate SMS but critical products are installed using 
VOLSER. The problem is having 3 systems in a SYSPLEX but you only want 1 using 
the newest updates for 1 product. Using SMS requires DSN changes instead of 
simple 

Using &VOLSER instead of &DISTVOL, &RUNVOL, &TARGVOL and &GLOBVOL means that 
your customers must determine when each dataset is needed.
