So do we, 2 CFs per Sysplex (you "cannot" run a production site with only 1). I am a little confused about your questions: System managed rebuild is standard and always active. This will rebuild structures in another CF in case of problems. It is transparent to the application, be it with some

Peter, Using FETCHABLE gives me the same error. With OS_DOWNSTACK I get the followig when I build: CCN6404 (W) The parameter "OS_UPSTACK" specified for "pragma linkage" is not valid. The pragma is ignored. I ran it anyway and got the same thing. I can't believ

Thin interrupts were introduced as a performance booster for shared CF engines. However when we recently upgraded both CECs to z14 and z13, we discovered that we can no longer live with 'fat' interrupts. In a new CEC, thin interrupts must be enabled by CF command; there is no profile to carry ov

Hmm-m-m. Maybe #pragma linkage (IGGCSI00, OS_NOSTACK) would work? Also, investigate your C compile listing, what is the compiler option XPLINK set to? I get the impression from RTFM about the XPLINK option that XPLINK(OSCALL(NOSTACK)) is the default when LP64 is in effect, is that true for y

I agree the original question was a bit confusing, but to answer it directly: -> System-managed duplexing is definitely not deprecated, but yes there is an "overhead" to run system-managed duplexing for structures, which is why a new enhancement was recently released on z14 (CFLevel 22 and up)

We want to discard some very old tapes after making sure there's nothing of value on them. When we run Innovation FATAR to analyze them, the jobs fail with messages like those below using JCL like this: //TAPEIN DD UNIT=TAPECR,LABEL=(,BLP), // DISP=OLD,VOL=SER=(nn) There's a

This is CA-1, but I thought RMM was compatible. And, I there are SAF profiles controlling access. CA-1 defines it's own class for them EXPDT=98000 Nonresident EXPDT keyword. Specifies that the tape volume being processed is not under CA 1(r) Tape Management System control > -Original Messa
