CMS SIZE

[Huegel, Thomas]

I have a simple question for anyone that has z/VM 5.2 running.
I seem to remember someone saying that the size of CMS machines needs to be
increased on 5.2.
I am sure the validity of that statement depends on what release one is on
before going to 5.2.
I am on z/VM 4.3.
The book states that the minimum for 4.3 and 5.2 are both 2M to IPL CMS and
20M for IPL 190.

Most of my 100+ CMS users are at 8M now.
Will 8M suffice or should it be virtualized to 16M? Any opinions?

Thanks

IIRC, it had to do with the LE (language extension) increasing in size or
being moved above line or something like that. I don't recall a value
being mentioned.
For example, "add x more meg to each userid that uses LE"

It would appear that the real answer is that most users will probably run just fine with their current machine sizes. It is the ones using TCP/IP who may need larger machines.

This was because of TCP/IP's expanded usage of C. Testing showed doing PING and NETSTAT commands may need up to 5M more. IBM Level-2 suggested going to 32M (as much as 64M is will not expand what was called the page and segment tables).
