Why not use DB2 HADR and then you can just do the takeover command?

I wrote a character device driver that allows you to use
open/close/ioctl/read/write semantics to do IUCV communications. There are a
couple of source RPMs at https://download.sinenomine.net/fsiucv. Use the -3
series. Note, they are tied to a kernel level so the spec file would need
adjusting.

We have a .service file of type forking that calls a script of ours to
start it and stop it.
systemd is cool with that.
However, if you stop and then start db2 outside of db2 it's no longer
associated with that service and systemd whacks its processes at shutdown
time, resulting ge
Hello, I realize that this is not a typical s390 question but I hope that's
ok if I ask anyway. There is a high chance we have people here who run db2
on zLinux.
How do you solve auto start and more importantly auto stop of DB2 on
start/reboot/shutdowns ?
Seems like the autostart may be handled by

Thanks Ursula,
I wasn't clear if this was a call for me to justify what I am trying
to do, but I thought
I might mention it.

The tracepath command should be able to show you that without a lot of
trial and error.

Hi everyone,
In my company I need to set up a HA NFS cluster on RHEL 7 running on z/VM 7.1.
But my company doesn't have a subscription for the Red Hat High Availability or
the Resilient Storage Add-On. So I build the packages for pacemaker and pcs,
used the drbd packages from the epel repositor
Neale: I am trying to do some TCPIP socket operations from Linux.
My hope is to be able to create a zLinux daemon that can listen to a port
from a given VM TCPIP stack.
As Alan said, all VM TCPIP seems to be 2WAY which is why I
am a bit stuck on this issue it seems.
I am considering forking the a
I may be wrong but I think the Guarded Page facility is about load
references. This could e.g. help Java to determine hot versus cold objects
without generating too much overhead. As such it could therewith also
assist determining the active working set ... but in the end the question

There have been different things discussed, though I don't recall if
guarded storage facility was one of them (actually introduced in z14) as
that came out after we did the initial LGR.

Could you take advantage of the guard page hardware facility of the z15 that
the pause-less Java garbage collector uses?

z/VM doesn't have a short cut to determine that no pages have changed. So
for a guest over 100GB, it has to examine over 26 million things multiple
times. Validating the I/O is drained is another aspect, but my guess is the
traversing of the DAT structures is the biggest factor.

Bill
