An Open Letter to Oracle for SPARC & Solaris

An Open Letter to Oracle for SPARC & Solaris


The Market had always wanted revolutionary improvement from systems and operating systems, in order to produce cost of ownership improvements and a competitive against other software players. Many promises were made from Sun Microsystems, some were carried out by Oracle after acquisition, but there are still many needed features that must be completed.

SPARC M8 Laundry List

There is really not much that is desired, with Oracle producing an amazing Hardware Architecture with Software Stack to run on top. With a processor running at 5GHz, 32 cores per socket, 8 threads per core, and 4 instructions per clock cycle, hardware crypto-decrypt units, hardware decompression engines, Java streams accelerators, and Oracle RDBMS [numbers & query] accelerators - what else could be needed?

SPARC Trademark

The SPARC Trademark appears to be getting watered down, lately. More press releases are needed for the architecture, to exercise the rights of the holder, for legal purposes. The organization has seemingly gone mostly dormant, for the past number of years, with new Oracle partners in the SPARC environment not contributing press releases through the international organization. This needs to end. People offering emulation need to be participants in the trade group and contribute their dues, which are very small.

With competing organizations, like IBM, now owning Red Hat Linux, Oracle is left with the most scalable hardware in the market, with access to only a few select larger customers. The hardware reach must go downward, which IBM now has with their RedHat Linux on single board computers.

From a hardware perspective, scaling small for Makers and scaling big for Industry is needed:
- Intel CPU has proven itself as a terribly risky proposition to RISC, with never ending streams of security vulnerabilities - a commitment to secure SPARC is needed more than ever!
- Optane / QuantX / 3D XPoint NVRAM from Intel / Micron must be accommodated in a useful way, perhaps a native chassis interfaces controlled by firmware for persistent ARC, L2ARC replacement, or SLOG intent log replacement.
- a shrink of die, if for nothing else than re-adding future integration
- - network integration to a SPARC die for makers less expensive storage nodes
- - cross-bar switch for vertical scalability in single chassis for SMP systems
- - InfiniBand endpoint, for glue-less MPP integration or engineered systems
- - Memory, for inexpensive Compute Nodes in an engineered system
- a hardware compression engine has always been missing, to make 100% compressed datasets as native as 100% encrypted datasets
- 1 TB addressability per socket is a good start, but there needs to be a drive towards 2TB or 4TB of memory per socket, to work with ever increasing datasets.
- an Open Source 1x core 8x thread implementation, single board SPARC platform for Makers
- an Open Source OpenFirmware implementation to be used on a single board SPARC platform, for Makers
- an active push into the Universities & High Schools with single boards running Open Firmware and Solaris

If Oracle wishes to stay relevant, they must be more than a hardware knock-off company and start feeding the market with desire for their products from the lowest levels.

With competing organization, like IBM, now owning RedHat Linux, Oracle is left with the most scalable OS in the market (Solaris), with Engineered Systems based upon a knock-off version of IBM RedHat Linux. The software reach must go downward & broader with Solaris.
- Open Firmware needs to be re-released & re-spec'ed by the IEEE, so makers to have a future
- promises for rebootless-patching via K-Splice on SPARC must be delivered, as K-Splice has less of a future with similar rebootless patching now available on Linux (from other competitors like IBM, who own the OS that Oracle Linux is a knock-off of)
- promises for ZFS to expand out to a true horizontally scalable clustered filesystem need to be fulfilled, so perhaps small Solaris single boards can be combined for horizontal scalability
- A small version of Solaris, to run on small SPARC single boards, for makers
- A decision to support Java on SPARC, for makers to code in.
- A small Oracle RDBMS, to run on a SPARC single board, for makers, to make Oracle RDBMS relevant in today's computing environment
- Cooperation or Commissioning of Open Source Solaris alternatives, like Illumos, to run in the Maker environment, or ZFS Clustering, to maintain relevance to emerging human resource base.

When people come out of school today, they do not think of Oracle as a provider of anything. Software is a way to change this, and not by merely someone who copies IBM's operating system.

SPARC Solaris Cloud

Oracle released Solaris 11, as the First Cloud OS, yet only customers are building clouds with it.
- It is long overdue for Solaris 11 ZFS to provide block storage to Oracle cloud
- It is long overdue for Oracle RDBMS and Apps to run in Oracle Cloud under Solaris 11
- It is long overdue for LDom's to be available in a SPARC Cloud
- It is long overdue for Cold and Live Migrations of LDoms and Zones to an Oracle Cloud
- It is long overdue for Storage Migration of LDoms and Zones to an Oracle Cloud

This is not rocket science, as customers do a lot of it today, but it is time for Oracle to monetize on the Cloud with SPARC & Solaris, instead of refusing to provide visible cloud solutions to customers.

Your Own Destiny

It is written: Without Vision, The People Perish. A maker's dream might be a shrink of the M8 processor, with 1x core comprised of 8x threads, and the rest of the die filled with an ethernet & raw memory. A secondary version holding a crossbar on-die & headers on the board, so boards can be stacked on one another, similar form-factor to a Raspberry Pi, to create a scalable SMP platform. Allow OpenFirmware and Solaris to reside on it, while adding Oracle RDBMS on it, for educational purposes, and small business as a mini Oracle Database Machine (charge per additional board, aggregate ethernets for increased throughput.) End the dependence upon Intel & IBM & licensing other processors for the future - drive your own destiny. Facilitate third-parties to drive the hobby & educational & MPP markets (i.e. & while concentrating on the


The industry had watched, with great anticipation, the union of Oracle and Sun Microsystems. The creation of the fastest processors on the market, from SPARC family & a fabulous Solaris 11 OS has been the apex of computing, but resting  since 2017 is insufficient. A minor amount of investment or even just partnership with existing Open Source organizations is all that is needed to take Oracle to the next level - sustainability of Oracle SPARC, Oracle Solaris, and Oracle RDBMS for the next generation. With so many very good RDBMS's in the Open Source market on top of the Linux that Oracle copies from IBM RedHat, Oracle must decide to be a leader again, rather than a shell of a copy of competitors. Without advancing SPARC & Solaris, anyone can do what Oracle does.

Fujitsu: Updates SPARC Solaris Roadmap

Fujitsu: Updates SPARC Solaris Roadmap


SPARC has been an Open CPU Architecture, from the day Dave Patterson from UC Berkeley proposed what would become the SPARC architecture and became the industry-leading 64-bit microprocessor. Sun Microsystems engineers worked with Dave to define the SPARC architecture. Many manufacturers like Sun Microsystems, Fujitsu, and later Oracle briefly produced, and definitively produced the longest lasting 64-bit architecture in the market. Fujitsu continues to update their SPARC Roadmap!

[SPARC64 & Solaris Roadmap, courtesy Fujitsu Canada]

SPARC64 & Solaris Roadmap for 2020

In 2017, Fujitsu release a new hardware platform called the M12, with what was the fastest silicon in the world! The platform included Physical Domains, which allow for Physical Domains to get moved & split between various chassis when a system failure occurs. The industry was looking forward to an update to some of the finest system firmware in existence!

[SPARC64 & Solaris Roadmap, courtesy Fujitsu Global]

SPARC64 & Solaris Roadmap 2021

Fujitsu promised to have an updated SPARC64 chassis in 2020, It appears that chassis has slipped to 2021. One of the things this author requested of Oracle for their future Tx-2 Chassis was larger memory footprint. If we could see a Tx-2 chassis of 4TB or 8TB, that would be enough to bring these platforms ahead for the next 4-5 years, since processor speeds have topped-out, for the most part, or even decreased, on competing architectures, due to their inherent insecure instruction sets.


Oracle & Fujitsu had taken the market a very long way with SPARC architecture, with competitors still light years behind. The platforms are still the fastest in the market, file system most advanced in the industry, and firmware the most capable. There is a short wish-list that is needed, to fill some gaps, but that is for another blog entry.

SSH Timeout Across a Firewall

SSH Timeout Across a Firewall


Firewalls represent a "choke point" between a Data Center and The Internet. The function of the Firewall is to protect the Data Center from unauthorized & malicious access. This "choke point" also typically terminate socket connections which have been idle for extended periods of time, to reduce unnecessary connections which need to be statefully inspected. This termination of idle sockets will sometimes stop the normal functioning of administrative sessions over SSH where longer running interactive jobs (i.e. backups, software installs, manual data loads, etc.) and corrupt databases. KeepAlive functionality in SSH can be engaged to inhibit this behavior.

What is the Error?

When a firewall terminates the connection, the client connecting to the Solaris Server in the remote Data Center may exhibit the following error message:

Received disconnect from 2: Timeout, your session not responding.

And the connection is terminated.

In an outsourced Data Center environment, a controlling TTY over SSH connection was being terminated, when idle for 10 minutes, while manually running an interactive backup script (which produced no output to the controlling TTY over an SSH during the copy of a significant quantity of data across a WAN connection.)

What is a KeepAlive?

A KeepAlive packet is normally a 0 byte packet, sent along an open SSH session, on a regular interval, to keep a firewall from assuming the connection is idle, during longer periods of non-interactivity.

Even though it is a null byte packet, that does not add any additional data to the text sent or received by the application, the additional null byte packet has headers which are seen by the firewall, and keep the firewall from terminating the session because no traffic was seen.

How to Configure KeepAlive

Under Solaris 11.3, there is a system-wide configuration file which can be updated, on the server receiving the connections. By default, KeepAlive functionality is disabled under Solaris 11.3

SUN0101/root# egrep '(KeepAlive|ClientAlive)' /etc/ssh/sshd_config
# KeepAlive specifies whether keep alive messages are sent to the client.
#KeepAlive yes
ClientAliveCountMax 0
ClientAliveInterval 600

The following adjustment will enable KeepAlives to be sent every 120 seconds, while forcing a disconnection after 240 seconds, without responses (so the firewall is always getting data, and a truly idle connection will beterminated by SSH server, instead.)

SUN0101/root# egrep '(KeepAlive|ClientAlive)' /etc/ssh/sshd_config
KeepAlive yes
ClientAliveCountMax 2
ClientAliveInterval 120

A backup should be done to the original file, in case it needs to be rolled back.
Console access to the system will be needed, to perform the roll back, if ssh is mis-configured.

How to Enable KeepAlive

Changing the configuration file will not enable changes for new sessions, nor make changes to open sessions. If you wish to enable the change for new sessions, refresh the config through the services.

SUN0101/root# svcs ssh
STATE          STIME    FMRI                    .
online         May_03   svc:/network/ssh:default

SUN0101/root# svcadm refresh svc:/network/ssh:default

Any existing ssh sessions will be timed out by the firewall, within the configured limit.
Any new ssh session will not be timed out by the firewall, with the keep alive enabled.
Any new ssh session, which goes into an abnormal state where the client does not respond, will be terminated by the SSH service, in 2 minutes.


Network Management of Solaris Systems in Cloud based Data Centers is still quite usable, when firewalls are deployed by Cloud Providers and clean up idle connections.  These types of environments have long been used in mission critical arenas, with secured servers residing in DMZ's and ISZ's - so a remote data center with a perimeter firewall is just "old hat".

Building OpenJDK Under Solaris SPARC and x64

Building OpenJDK Under Solaris SPARC and x64

[Duke Thinking]


There has been must discussion regarding Java and Solaris, both SPARC, Intel x86, and AMD x64. Oracle had released Java into the wild, under a fast continuous release plan, and paid support plans for long term releases. OpenJDK is the reference release of JavaSE since Java 7. Once concern in the industry has been, how to we compile the latest versions of Java, and this has been discussed in detail by various authors to be cited.
[Duke Plugging]

Building OpenJDK 12 under Solaris:

Guest Author Petr Sumbera had published an article on Oracle's Solaris Blog on how to compile your own version  of OpenJDK 12. What is interesting is that it uses an existing JDK to perform that process!

To compile OpenJDK 12, SPARC Solaris requires JDK 8 under Intel Solaris and JDK 11 under SPARC Solaris. In addition, you will need Oracle Solaris Studio 12.4.

[Duke Drawing]

OpenJDK on SPARC Solaris:

In  March 2019, Oracle Author Martin Mueller also published an article on Building OpenJDK Java Releases on Oracle Solaris/SPARC. In addition, you will need Oracle Solaris Studio 12.4. This article may help in the build of of OpenJDK for SPARC.

[Duke Plumbing]

OpenJDK on Intel or AMD Solaris:

In February 2019, Birkbeck College, Computer Science Department, Author Andrew Watkins also published an article on Building OpenJDK 12 on Solaris 11 x86_64. This followed on his October 2018 article on  Building OpenJDK 11 on Solaris 11 x86_64. This followed on his September 2018 article on Building OpenJDK 10 on Solaris 11 x86_64. These articles may help in the building of OpenJDK for Intel or AMD systems.


The availability of the latest Java, license & support free, is available if one wants to roll their own. If commercial support is desired, Java can can still be acquired from Oracle with a Long Term Support (LTS) contract.

Distributed Denial of Service, Amazon Cloud & Consequences

[Amazon Web Services Logo, Courtesy Amazon]

Distributed Denial of Service, Amazon Cloud & Consequences


The US Military had been involved in advancing the art of computing infrastructure since the early days of computing. With many clouds built inside the Pentagon, a desire to standardize on an external cloud vendor was initiated. Unlike many contracts, where vendors were considered to compete with one another for a piece of the pie, this was a "live and let die" contract, for the whole proverbial pie, not just a slice. Many vendors & government proponents did not like this approach, but the proverbial "favoured son", who had a CIA contract, approved. This is that son's story.

Problems of Very Few Large Customers

Very few large customers create distortions in the market.
  1. Many understand that consolidate smaller contracts into very few large contracts is unhealthy. Few very large single consumers, like the Military, create an environment where  suppliers will exit the business, if they can not win some business, since the number of buyers is too small, limiting possible suppliers in time of war.
  2. Some complain that personal disputes can get in the way of objective decision making, in large business transactions.
  3. Others warn that political partisanship can wreck otherwise potential terrific technology decisions.
  4. Many complain that only a few large contracts offer opportunity for corruption at many levels, because the stakes are so high for the huge entities trying to gain that business.
  5. In older days, mistakes by smaller suppliers gave opportunity for correction, before the next bid... but when very few bids are offered, fleeting opportunities require substantially deep pockets to survive a bid loss
  6. Fewer customer opportunities discourages innovation, since risk to be innovative may result in loss of an opportunity when a few RFP providers may be rigidly bound by restraints of older technology requests and discourages from higher costing newer technology opportunities
In the end, these logical issues may not have been the only realistic problems.

Amazon's Business to Lose

From the very beginning, Amazon's Jeff Bezos had his way in. Former Defense Secretary James Mattis, hired Washington DC Lobbyist Sally Donnelly, who formerly worked for Amazon, and the Pentagon was soon committed to moving all their data to the private cloud. The irony is that Bezos, who has a bitter disagreement with President Trump, now had a proverbial "ring in the nose" of President Trump's "second in command" with the Armed Forces, in 2017.

Amazon's Anthony DeMartino, a former deputy chief of staff in the secretary of defense’s office, who previously consulted for Amazon Web Services, was also extended a job at Amazon, after working through the RFP process.

Features of the Amazon Cloud, suspiciously looked like they were taylor written for Amazon, requesting features that only Amazon could offer. Competitors like Oracle had changed their whole business model, to redirect all corporate revenue into Cloud Computing, to even qualify for the $2 Billion in revenue requirement to be allowed to bid on the RFP! How did such requirements appear?

Amazon's Deap Ubhi left the AWS Cloud Division, to work at the Pentagon, to create the JEDI procurement contract, and later return to Amazon. Ubhi, a venture capitalist, worked as 1 of a 4 person team, to shape the JEDI procurement process, while in secret negotiations with Amazon to be re-hired for a future job. The Intercept further reminded us:
Under the Procurement Integrity Act, government officials who are “contacted by a [contract] bidder about non-federal employment” have two options: They must either report the contact and reject the offer of employment or promptly recuse themselves from any contract proceedings.
The Intercept also noted that Ubhi accepted a verbal offer from Amazon, for the purchase of one of his owned companies, during the time of his working on the Market Research that would eventually form the RFP.

A third DoD individual, tailoring the RFP, was also offered a job at Amazon, according to Oracle court filings, but this person was marked from the record.

At the highest & lowest levels, the JEDI contract appeared to be "Gift-Wrapped" for Amazon.

Amazon Navigating Troubled Waters

December 23, 2018, President Trump pushes out Secretary of Defense James Mattis after Mattis offered a resignation letter, effective February 2019.

January 24, 2019, Pentagon investigates Oracle concerns unfair practices by hiring Cloud Procurement Contract worker from Amazon.

April 11, 2019, Microsoft & Amazon become finalists in the JEDI cloud bidding, knocking out other competitors like Oracle & IBM.

June 28, 2019, Oracle Corporation files lawsuit against Federal Government for creating RFP rules which violate various Federal Laws, passed by Congress, to restrict corruption. Oracle also argued that three individuals, who tilted the process towards Amazon, who were effectively "paid off" by receiving jobs at Amazon.

July 12, 2019, Judge rules against Oracle in lawsuit over bid improprieties, leaving Microsoft & Amazon as finalists.

August 9, 2019, Newly appointed Secretary of Defense Mark Esper and was to complete "a series of thorough reviews of the technology" before the JEDI procurement is executed.

On August 29, 2019, the Pentagon awarded it's DEOS (Defense Enterprise Office Solutions) cloud contract, a 10-year, $7.6 billion, to Microsoft, based upon their 365 platform.

On October 22, 2019, Secretary of Defense Mark Esper withdrew from reviewing bids on the JEDI contract, due to his son being employed by one of the previous losing bidders.

Serendipity vs Spiral Death Syndrome

Serendipity is the occurrence and development of events by chance with a beneficial results. The opposite may be Spiral Death Syndrome, when an odd event may create a situation where catastrophic failure becomes unavoidable.

What happens when an issue, possibly out of the control of a bidder, becomes news during a vendor choice?

This may have occurred with Amazon AWS, in their recent bid for a government contract. Amazon pushed to have the Pentagon Clouds outsourced, at one level below The President and even had the rules written for an RFP, to favor a massive $10 Billion 10 year single contract agreement favoring them.

October 22, 2019, A Distributed Denial of Service (DDoS) hitsAmazon Web Services was hit by a Distributed Denial of Service attack, taking down users of Amazon AWS for hours. Oddly enough, it was a DNS attack, centered upon Amazon C3 storage objects. External vendors measured the outages to last 13 hours.

On October 25, 2019, the Pentagon awarded it's JEDI (Joint Enterprise Defense Infrastructure) cloud contract, a 10-year, $10 billion, to Microsoft. The Pentagon had over 500 separate clouds, to be unified under Microsoft, and it looks like Microsoft will do the work, with the help of smaller partners.


Whether the final choice of the JEDI provider was Serendipitous for Microsoft, or the result of Spiral Death Syndrome for Amazon, is for the reader to decide. For this writer, the final stages of choosing a bidder, where the favoured bidder looks like they could have been manipulating the system at the highest & lowest levels of government, even having the final newly installed firewall [Mark Esper] torn down 3 days earlier, is an amazing journey. A 13 hour cloud outage seems to have been the final proverbial "nail in the coffin" for a skilled new bidder who was poised to become the ONLY cloud service provider to the U.S. Department of Defense.

(Full Disclosure: a single cloud outage for Pentagon Data, just before a pre-emptive nuclear attack on the United States & European Allies [under our nuclear umbrella], lasting 13 hours, could have not only been disastrous, but could have wiped out Western Civilization. Compartmentalization of data is critical for data security and the concept of a single cloud seems ill-baked, in the opinion of this writer.)

How to Kill a Zombie in Solaris

How to Kill a Zombie in Solaris


When a parent spans a child process, the child process will return a signal to the parent once the child process has died or was terminated. If the parent dies first, the init process inherits the children, and will receive the signals once the children die. This process is called "reaping". Sometimes, things do not go as planned. It is a good topic for Halloween.

[artwork for "ZombieLoad" malware, courtesy zombieloadattack]

When things do not go as planned:

It may take a few minutes for the exit signal to be reaped by a parent or init process, which is quite normal.

If children processes are dying and the parent is not reaping the signals, the child remains in the process table and becomes a Zombie, not taking Memory or CPU, but consuming a process slot. Under modern OS's, like Solaris, the process table can hold millions of entries, but zombies still consumes kernel resources and userland resources when process tables need to be parsed.

Identifying Zombies

Zombies are most easily identified as "defunct" processes.
# ps -ef | grep defunct
root 1260 1 0 - ? 0:00 
This defunct process would normally be managed by the parent process, which is "1" or init, but in this case we can clearly see that this process is not disappearing.
# ps -ef | grep init
root 1 0 0 Oct 25 ? 8:51 /sbin/init
But why call them Zombies and not just Defunct?
$ ps -elf | egrep '(UID|defunct)'
 0 Z root 125 4549 0 0   -  -    0  -     -     ?   0:00
The "S" or "State" flag identifies the defunct process with a "Z" for Zombie, and all can see them.

(Plus, this is being published on Halloween, or All Hallows' Eve, the day before All Hallow's Day or All Saints' Day... this is when people remember the death of the "hallows" or Saints & Martyrs, who had passed on before. So, let's also remember the deaths of the processes!)

[The Grim Reaper, courtesy Encyclopedia Britannica]

To Kill a Zombie:

How does one kill a Zombie?
Well, they are already dead... in the movies, they are shot in the head.
In the modern operating system world of Solaris, we seek the reaper, we Don't Fear The Reaper.

The tool is called Process Reap or "preap" - the manual page is wonderfully descriptive!
# preap 1260
1260: exited with status 0
It should be noted, processes being traced can not be reaped, damage can occur to the parent process if the child is forcibly reaped, and the OS may also put restrictions on reaping recently terminated processes.

To force a reaping, one can place a proverbial "bullet in the head" of the zombie.
# preap -F 125
125: exited with status 0
So, there we go, two dead zombies, see how they no longer run.


This administrator had personally seen poorly written C code, leaving thousands of zombies behind daily. The application  development team no longer had no C programmers on their staff, so this was a good option. It should be carefully exercised on a development or test box, to evaluate the results on the application, before conducing a procedure in production.

Concluding Thoughts

It is always good to get news on the SPARC Solaris front, for those workloads which do not run as well on other platforms.
