Solaris X86 on OCI BareMetal or Virtual Machine?

For Solaris workloads Oracle Cloud Infrastructure (OCI)
offers multiple options: Bare Metal and Virtual Machine
on AMD or Intel CPUs.

With Virtual Machines you are flexible with Memory and CPU
Configurations. From 1 OCPU (core) up to 64 and up to 1 TB RAM.
Depending on your load you can change the size of the VM, but
you need to reboot to activate the VM with the new settings.

Bare Metal have fix sizes from 512 GB RAM up to 2 TB and
between 36 OCPU up to 160 OCPU. The available shapes
may be limited on your cloud region.
Bare Metal have currently the limitation you can't attach
UHP (Ultra High Performance) block volumes.

For both types Bare Metal and VM you are not charged if you shutdown
your instance.

My current favorite is the VM type because of the flexibility to resize.
So far I did not encounter high performance impact by the Virtualization layer.

Solaris 11.4 x86 in Oracle Cloud OCI VM

Oracle currently offers the Oracle Cloud in 40 regions.
One of the many options available is a Solaris 11.4 x86 Virtual Machine.
You can create a VM with up to 1TB RAM and 64 OCPUs (cores).

The creation is very easy and the setup is done in a few minutes.

How to create a VM can be found on the Oracle Solaris Blog


The OS management is currently not available to monitor the Solaris instances.
The commercial JomaSoft VDCF tool is an option to be used for monitoring.

I/O performance depends on the configuration of the block volumes and on
the CPU resources used by the Virtual Machine.
But even with 16 cores I never reached more than 100MB/s

Solaris 11.4 SRU51 (Nov 2022) - virtinfo enhancements for Solaris Zones

In the past virtinfo provided only minimal information about the underlying global zone.

SunOS marcel49 5.11 11.4.47.119.2 sun4v sparc sun4v non-global-zone

The serial is helpful if you need to open a case with Oracle Support.

How easy is it to import OpsCenter created systems into JomaSoft VDCF ?

Ops Center is Oracle's management and monitoring tool for Oracle Solaris.
Premier Support for the current version 12.4 ends April 2024.

JomaSoft VDCF is a lightweight CLI management and monitoring tool with similar features.
VDCF could be an alternative for customers with focus beyond April 2024.

Find more information about VDCF
https://www.jomasoft.ch/vdcf/

This blog shows how easy it is to integrate systems created using OpsCenter into VDCF.
After the import VDCF can be used to operate, manage, update and monitor this systems.

We will import 3 systems into VDCF. First the SPARC S7 control domain and then two LDoms
where one is running Solaris 10 and the second is running Solaris 11.4. The process is done in a few minutes. It is required to execute 2 commands on each system to install the JomaSoft VDCF Client pkg and add the required ssh key.

Step 1 / Install VDCF pkg and key on each target system

Step 2 / Import the systems into VDCF

The step to integrate the systems into the VDCF tool is by executing a single simple node import command on the VDCF central management server.

First we have to import the control domain.

Using Ops Center on current Solaris 11.4 SRUs is a fight

Ops Center causes troubles, because it uses old software versions,
which are not available anymore by default on current Solaris 11.4 SRUs.

It requires python 2.7 & perl 5.22

On Control Domains using SRU48 or later you even need to open a Oracle Support Service Request to download a required Agent bugfix.

Here a few MOS Doc Ids with details about the workarounds

Ops Center 12.4: CDOM Agents fail to start after a Solaris upgrade to 11.4 SRU 48 (Doc ID 2892465.1)

Ops Center 12.4 upgrades to Solaris 11.4 SRU 39 on an EC will fail (Doc ID 2826475.1)

Ops Center Will Not Start After Upgrading to Solaris 11.4.3- SRU 30 - Svc:/application/scn/ajaxterm:default is Restarting Too Quickly (Doc ID 2760685.1)

Ops Center: Running With Solaris 11.4 SRU21 or Higher Precautions (Doc ID 2783309.1)

If you are happy with CLI tools, the JomaSoft VDCF framework is an alternative management software.

Support State of Oracle SPARC T5-2 Server

The SPARC T5-2 is a very successful server, but a bit old now.
Oracle shipped the last T5-2s five years ago in 2017.

Oracle still supports this server, but after 5 years after Last Ship
replacement parts delivery is not  guaranteed anymore.

But there are newer generations of Oracle SPARC servers available
with faster CPUs and Memory and less use of power. There are various
options to migrate the existing Ldoms, Zones or Apps to the new servers.

Take a look at the new SPARC servers at

Solaris 11.4 SRU45 (May 2022) - zstd compression utility

Solaris 11.4.45 includes now the zstd compression utility.

-bash-5.1$ zstd -V
*** zstd command line interface 64-bits v1.5.0, by Yann Collet ***

To compare I have a Oracle DB19c home as a tar file.
I executed this tests on a SPARC S7 LDom with 1 core

# ls -lh 19c.tar
-rw-r--r--   1 root     root       6.66G May 23 17:36 19c.tar

zstd does a higher compression compared to lz4, but takes
more time.

# time zstd 19c.tar -o 19c.tar.zstd
19c.tar              : 39.24%   (7153274368 => 2806612298 bytes, 19c.tar.zstd)

How to Migrate from Solaris 10 to Solaris 11

Solaris 10 was released in 2005. Currently Solaris 10 is in extended Support
and Oracle is planing to provide patches till 01/2024.

Great News About Extended Support for Oracle Solaris 10 OS

There is no easy upgrade from Solaris 10 to 11 because Solaris 11
includes many new features not available in Solaris 10.

best option
At our customers we install new Solaris 11 systems or LDoms and install
the application, do the configuration and move the data from Solaris 10.

compromise option
If your application is not supported on Solaris 11 or you want to migrate
away from older hardware in short time. Then your option is Solaris 10 Branded
Zones. You can install Solaris 10 Branded Zones on a Solaris 11 server
based on a 1:1 archive from your Solaris 10 System.

Lift and Shift Guide - Migrating Workloads from Oracle Solaris 10 SPARC Systems to Oracle Solaris 10 Branded Zones


next step: sysdiff
If you already have a Solaris 10 Branded Zone, you can use the new sysdiff tool
to identify application binaries and files and convert this into a Solaris 11 ips package.
This ips package can then be deployed on a Solaris 11 Server.

sysdiff: moving Oracle Solaris 10 legacy 3rd party apps to 11.4

Solaris 11.4 SRU42 / Non-Production Personal Use Update

For developers Solaris 11.4 GA was made available in 2018.

Updates/SRUs are (only) delivered to customers with support contract.
Since Oracle changed to the continuous delivery model there was
no update for developers since 42 months.

This changed today !!

The public Solaris IPS repository contains the SRU42

http://pkg.oracle.com/solaris/release/en/index.shtml


More details on:
https://blogs.oracle.com/solaris/post/announcing-the-first-oracle-solaris-114-cbe

Solaris 11.4 SRU42 (Feb 2022) - /var/share/cores FS and coreadm defaults

/var/share/cores is now a separate filesystem

-bash-5.1$ zfs list rpool/VARSHARE/cores
NAME                  USED  AVAIL  REFER  MOUNTPOINT
rpool/VARSHARE/cores   31K  22.1G    31K  /var/share/cores

If you upgrade from a previous SRU to SRU42 or later,
cleanup /var/share/cores first, because the files
will be migrated to the new filesystem.


coreadm has now better defaults for the core file naming

root@marcel49:~# coreadm | head -3
     global core file pattern: /var/cores/core.%z.%f.%u.%p
     global core file content: default
kernel zone core file pattern: /var/cores/kzone.%z.%t

with this new core file pattern, the cores can be easier identified
and are less often overwritten.

root@marcel49:~# ls -lh /var/cores/core.marcel49.sleep.0.21198
-rw-------   1 root     root       4.16M Feb 25 13:19 /var/cores/core.marcel49.sleep.0.21198

If the pattern was not configured before the upgrade to SRU42 or later
the new default is set automatically.

If you used another pattern before you upgraded to SRU42 or later
you can set it manually to the new standard/default.

coreadm -g /var/cores/core.%z.%f.%u.%p

Solaris 11.4 SRU42 (Feb 2022) - LDom Migration Class 2

SRU42 introduced a new LDom Migration Class. This class
allows to do Cross CPU Live Migration between SPARC S7,M7 and M8
CPUs. LDoms using this migration-class2 can use the ADI features
of this new CPUs and still can Live Migrate between this modern
SPARC Servers.

To change the cpu-arch setting you need to shutdown and unbind
your LDom

# ldm stop g0061
# ldm unbind g0061
# ldm set-domain cpu-arch=migration-class2 g0061
# ldm bind g0061
# ldm start g0061

The JomaSoft VDCF Management Software recognises this new
cpu-arch with Version 8.2.2 or later.
