Prior to SFS IBM sold something called File Sharinge Facility (FSF). If anyone 
has complaints about SFS they should have tried FSF at some time in their lives.
My memory is vague (we always try to forget pain) but I remember spending about 
two years trying to get that monster to live nicely. The distribution was all 
source code that had to be assembled and linked, and patches to CMS and CP (I 
think) and acquiring HLASM (why do we still have to pay for that anyway?). 
After about 2 years, several IBM SE's, and more than a few system crashes we 
were about to give up on the whole idea. 
Then along came SP6 with SFS built in and it was free... Really it was a 
blessing.

I also agree that 20 years later the interface for filepool creation and 
maintaince could be better. It would be nice if SFS, Dirmaint and RACF all 
'spoke the same language'.. 
That's my two cents (three hundred and eighty more and you can buy a gallon of 
gas).

It's not a lie, David.  In fact, on other platforms you MUST provide a 
side file to provide the metadata APPC needs.  Because VM implements a 
cluster of virtual machines as well as a cluster of VM instances (APPC 
Collection), we can take liberties with default metadata.

It has always been the architecture of APPC/LU 6.2 that applications make 
symbolic references to resource managers.  The local system (LU) performs 
a local lookup.  This is just as "arca
Again, a communications protocol that has been in place for decades.

So, the point is that you can EASILY redirect SFS connections.  Yes, you 
have to know how to do it or the book must tell you to do it.

Now, the DFSMS situation is a little different since I don't think you can 
choose the filepool name at install, or easily change it later.  The 
fully-qualified name of the config file should be specifiable in some way.
