IBM program products apparently have packaging rules for Unix libraries
stating that the path to these libraries will be /usr/lpp/<product_name>/.
How do shops handle this when they install program products (like
PrintServe, DB2, NetView, etc.) in other than their main MVS SMP zones.
In particular, how do shops handle maintenance or new releases when both
old and new copies of the products needs to be executed simultaneously?

Symbolic links so that /usr/lpp/<product_name>/ can point into different 
HFSs?  Temporary installation into something other than 
/usr/lpp/<product_name>/? Some other technique?

That 2nd technique was sometimes used at my last shop, but apparently 
some products use hard-coded paths /usr/lpp/<product_name>/.../.  Is 
that common, standard practice in MVS program products?  To have the 
paths to Unix libraries hard-coded and not overridable by installations?


I probably asked a question similar to this about a year ago, but couldn't
find it in the archive.
