the structures for a classlen of 12220 (12K-68) as that should make the
structure big enough to satisfy the above principals on average. Of course,
that will make you even less happy with the structure size.

"Setting Up A Sysplex" mentions the previously cited suggestion that XCFAS be
TRUSTED so ARM will work.
It also mentions using TRUSTED so XCF can access ICSF services (for CF
structure encryption) and BCPii services (so XCF can automatically detect and
isolate failed systems).
A search of the bo

factors that can contribute to these conditions: "no buffer" condi
If you run the policy utility IXCMIAPU to create/replace an administrative
policy in the CFRM CDS, then for any structure definition that specifies
ENCRYPT(YES), the system will create an encryption key for that structure
provided the CFRM CDS does not already have a key for the structure. That
Right, I'm not aware of a UUID for a z/OS system.
Every system in a given sysplex must have a unique name. In that sense
SysplexName.SystemName might do the trick. But ...
Sysplex names are not necessarily unique -- test sysplex or DR site could be
using the same name.
FYI, XCF does provide a "sysplex ID" that can be used to uniquely identify a
sysplex for the life of the sysplex. That could be used to distinguish between
two different sysplexes with the same name. A new sysplex ID is generated each
time the sysplex starts fresh.

largish Cobol Copybook more than 64 bytes".
The "notes' in a note pad can each be up to 1024 bytes.

It may not help, but be aware that the XCF SysplexID and SystemID have a good
chance of being unique if you need to identify an instance of a z/OS IPL across
the universe of sysplexes. These IDs are available via IXCQUERY macro using
REQINFO=COUPLE.

The key piece of information missing from the discussion is the abend reason
code that would have been issued with the XCF abend code 00C. The reason codes
meant for customer consumption will be documented with explanations in "MVS
System Codes" book; anything else is likely an "internal error"
Q1-
Should one define/use LOCALMSG in COUPLE00 ?
I've seen some sites do, some don't.
Ans: That's because it depends. If you are experiencing "no buffer" conditions
for local messages, you might need to increase the amount of buffer space.
Q2-

The signal counts are 4 byte counters, they'll wrap to zero after they reach

My guess is that the authors of the Redbook saw that the IXC344I msg allowed 10

commas. But it's not.
