Ken,
FlashCopy consistency group "should" give you the same P-i-T as Synch and
Asynch Remote Copy. Sounds like you should report a problem.
Attended a few DR rehearsals where JEs2 has warm started without a hitch.
Have you tried ShadowImage At-Time split (if you have HDS)?

When running from the USS command line I can specifiy -Xdump:none and suppress
the Java dumps and traces. Then if I get an abend I get the CEEDUMP which is
much more useful. Where do I specify -Xdump:none in the EXEC=JVMLDM66 JCL?
Does it go in the STDENV or is it an argument?

As we have no plans to use HIS sampling (which I presume is what makes use

future.

You could build a batch job or rexx to read a dataset list to search those

You should look at the description of the RDJFCB macro in the DFSMSdfp
Advanced Services manual. It appears you have the option of selecting which
dataset in the concatenation you acquire data for. Once you have the JFCB
for the dataset, the DSN should be in there.

you would never know it if you were missing .1% of the events that were coming

IIRC the type 70 record can be intercepted by IEFU83 when written by RMF,
however you need IEFU84 when it is written by CMF.
I would advise that you code your IEFU8x code to the requirements of IEFU85
just in case things change.

As far as I know a low UIC count right after an IPL is normal. I don't have a
z/OS 1.13 system, but on our z/OS 2.1 and z/OS 2.2 systems do show a low UIC
count after an IPL. The count gets higher over time. I think this is just the
nature of the UIC.
