Hello,
I hope someone can share the experience or put some light on the problem. I
will refer to elasticsearch as "ES" in this email.
We are running 2 Openshift clusters on 1 zVM LPAR (16 logical CPU , SMT2).
Cluster 1 (development workload):
3x Master node (each zLinux 8 vCPU) (VSWITCH-1 V
Hello,
I have the following network configuration scenarios. In scenario 1 -
physical network infrastructure attached to Mainframe is not involved in
communication between two zLinux hosts and traffic is handled on zVM level
, is it a correct assumption ?

Hello,
I also thought that enabling SMT will degrade performance of a single
threaded process, but I could not find anyone to confirm that. Thank you
Christian.

Postgres is not constrained by having only 4 cores. It's running fine with

dropped from 95% to 60%. On the other hand, I'm wondering if it negatively
affected single threaded workloads?

Hello Group,
We have 4 IFL on Mainframe box, 4 IFL on zVM and 4 cpu on zLinux. I'd like
to gain zLinux capacity (run more processes) and increase to 16 cpu. Will I
degrade performance of a single threaded workload if I do this?
All the best,

Hello Chris,
If you are on zVM, then Boot SLES into installation mode (from VM reader
using image and parm file). Temp root password and IP is specified in parm
file. Then you connect via ssh, activate dasd, mount and chroot (look into
Sles Admin guide "repair bootloader")

Hello,
FYI. To make linux LDAP client working with AD, I had to add posix
attributes (uid,gid,uidNumber, etc..) to my AD user. I configured LDAP
client using "sssd" on SLES12 and I'm happily authenticating against AD.
Thanks for help,

Hello,
If someone is planning to run TSM client > v 6.4.3 on z14, then ask IBM to
provide you gskcrypt and gskssl package at least 8.0.50.84. It fixed the issue.
