Forms 12C customers should know this. The jar files/the standard code delivered by Oracle is signed with the Digicert certificates and these certificates, which are there for the code signing, are used ensure the security on the client side. I won't go into the details of how code signing works, and I suppose most of my followers already know this. Here, I want to share something interesting.. This is based on a true story, on an issue escalated to me. The environment was a clustered Forms 12C (12.2.1.3). It was highly critical and very crowded.(3000 active users) The issue appeared suddenly a ..read more

I want to remind you something important regarding the Engineered systems. That is, as you may already know, the Oracle Supercluster M8 reached its End of Life (EOL) on June 30th, 2019. End of Life (EOL) signifies that Oracle no longer sells the hardware for the Supercluster M8. In addition to that, end of Support (EOS) status is also important.. EOS indicates that Oracle no longer provides guaranteed support for the system, including hardware replacement, bug fixes, and security patches. Well, last ship day of Supercluster M8 is Jun 2019. So, the premier support will end in June 2024. Afte ..read more

You may be hitting this bug even if your Oracle database version is 19C (even if it is 19.14..) You have a workaround (setting statistics_level to ALL), but it is not recommended.. (due to the fact that, you may end up collecting too much data for the  AWR snapshots) Note that, your AWR snapshot related data collection tasks may also take too much time to complete, if you set statistics_level to ALL.. especially if you have a large buffer cache... At the first glance, this problem seems addressed with the patch 22048821 TABLESPACE IO STATISTICS MISSING FROM AWR REPORT (Patch).. But it is ..read more

Found a quicker way to workaround the issue, that's why revisiting this  ->(https://ermanarslan.blogspot.com/2023/11/problem-installing-oracle-linux-7-and-8.html). Some background info: This problem is fixed in the Virtual Box Release version 7.0.12. In the problem-free Virtual box release 7.0.12, they commented that unsupported_hardware line in the default ks.cfg, that is delivered with the Virtual Box. That ks.cfg is automatically used in unattended installation, as you may guess. Therefore, the unattended installation works properly in 7.0.12. The Quicker Way -> So,  If you ..read more

As an Oracle ACE PRO + System and Database Senior Director, I was the guest of University TV's Professional Agenda Program. We had a nice conversation about my areas of expertise with the host of the program. We had some chats on AI and Quantum Computing, too. We discussed proper career planning for university students. We talked about curiosity and passion in this context. This was a live broadcast on Wednesday, October 18, 2023. Nowadays, offers are coming one after another for me to participate in the TV programs and I am starting to enjoy it :) Here I 'm leaving some photos from the l ..read more

Let's do some Linux & virtualization gymnastics by going through a real life problem. Getting unsupported command: unsupported_hardware error during Oracle Linux 7 (and 8) installation on Virtual Box 7.0.10 (a very up-to-date release of Virtual Box release at the moment).  The installation couldn't start actually.. It was terminated due to the unknown command error. (note that, this is not related with hardware.) That error message may be a bit misleading in the first glance.. Having unsupported_hardware there make it a bit counter-intuitive.. The real error is the unknown command err ..read more

Intro: Oracle databases have the ability to integrate with many applications and systems today. Web services are frequently used during these integrations. However, these integrations do not always occur smoothly. The problem we encountered occurred when calling a web service API from the Oracle database via PL/SQL code. This web service had a critical role in the application, so we had to solve this problem. The issue appeared when tried to access a web service using the HTTPS (TLS.1.2) protocol. The client (Oracle database in this case) encountered an unexpected error message.. Oracle Databa ..read more
