the link I posted answered the first part of Your question ( the way You posted it )
Named Counter Server need/nice to have
the need can be explained by looking at the issue from an application point of viewstart widening Your scope of vision
all depends on what You mean by
relatednamed counter servers and
shared temporary servers are not
related,
cics manuals talk about them in the same place because sharing in a sysplex
using the coupling facility has common sets of rules and concerns that apply to both!
for example
There is no difference between the temporary storage server and the named counter server relating to recovery, in that both servers store all of their data in the coupling facility structure, so it will be lost if the structure fails or the coupling facility is re-IPLed.
I was just wondering if anybody has some specific findings to discuss
kind of catch 22
if people replying had findings to discuss they would start asking, wouldn' t they since You did not really tell clearly Your concerns, it is difficult for us to find something to talk about!
