What does the "IA64_32" option mean in the architecture plugin details. The complete list of options is here, but there is no detailed explanation.
osgi.arch processor architecture x86, x86_64, ia64, ia64_32, ppc,
PA_RISC, sparc
The problem I am facing is that I have 2 implementations of the same interface, one for 32 bit set with x86 and another for 64 bit set with x86_64,ia64, but for some reason neither start when I install the 32 bit version of the application on a windows 2012 server r2 64 bit.
Many thanks in advance.
ia64 and ia64_32 are for Intel Itanium processors (64 bit and 32 bit respectively I think). Eclipse only uses this for HP-UX support. Recent releases of Eclipse only support ia64.
Windows builds normally use x86 (32 bit) or x86_64 (64 bit).

I'm trying to install Oracle jdk 17 on my netbook but with no success.
The installer says that the processor (Intel Atom Z3735F) is not supported.
On my desktop Intel i5 the same package is working fine.
I need Java on the netbook to bring at school.
Edit:
The netbook is running on Win 10 Home 32bit on Atom 64 bit processor.
I did a fast research I found out that the CPU (processor) you're rocking on your netbook is quite outdated today - it's from 2014 (check Intel Atom Z3735F on the official website). But it surprisingly should not be the issue (well, it might be - some instructions might be outdated, but I don't think that's the problem), because it actually is 64-bit CPU (it support 64-bit instruction set and it can address more memory - thanks to the wider address bus, OS has to support this as well). Since the new Java JDK 17 LTS is for x64 (64-bit) systems only, and you said that the installer reports that it's not supported on your device. I think that you're not using 64-bit operating system (OS). Do you think this could be the issue? You could easily find out by just easily looking at the task manager to see how much GB (gigabytes) of RAM you got. If it's 4 GB or less, then it's quite obvious thing. To make yourself sure, just type out systeminfo command to the CMD (if you are on Windows) and there under System Type record you will see what type you got (x86-based PC or x64-based PC).
Edit: If you are looking for the latest JDK release by Oracle that supports 32-bit systems, then JDK 13 would probably be the best go for you. If you don't need the features introduced in these newer releases, then I would recommend Java JDK 11 LTS, because it's going to be supported until September 2026. And as mentioned by matt in the answer, there is also JDK 17 LTS for x86 systems (32-bit) by Adoptium. Well, or reinstall the 64-bit OS, but that is probably the hardest option.
Thank you all for pointing me to the right direction.
The issue was caused by the 32bit Os
As suggested by #matt , I installed Adoptium JDK17 x86 that solved my problem.
According to openhab tutorial they said that openhab developers should use JDK 8 - 32 bit for Mac OSX, How can I install JDK 8 - 32 bit, the only available version of JDK 8 is 64 bit !
I believe you have misread the documentation. This page notes that you must use 32-bit Java on ARM chips, rather than 64-bit.
Please use the 32-bit version of the JVM for ARM platforms, even on 64-bit operating systems. Serial connections won't work with a 64-bit JVM, preventing bindings like Z-Wave from functioning.
ARM chips are used in many of the home automation devices and used in computers such as the Raspberry Pi. But ARM chips are not used in Macs, which currently use 64-bit Intel Core chips.
According to this Question, Java apps are agnostic regarding their host OS being 32-bit or 64-bit. Only native-code libraries called from Java may care about 32/64 bits of the host OS.
I’m not a user of OpenHAB, so I’m not certain
I give up… Stack Overflow is losing my edits.
All the recent Macs run 64-bit macOS.
If you still want to install JDK32 bit, you can have any OS using a virtual machine (VMware Fusion, Parallels, or VirtualBox) and then install JDK inside that VM.
For the openHAB recommended is to use Zulu.

Our java application is running on Windows platform and it uses 32 bit Windows dlls (which are difficult to port to 64 bit).
Is there any chance a Windows x86 release can be provided for Amazon Corretto 11 (like Corretto 8)?
Please advise. Thanks a lot.
Since JDK 9, almost all available JDKs are 64 bit only. Azul Systems had a JDK 10 32-bit for Windows that I downloaded and used, however when I searched the Internet just now, I couldn't find it.
I have a 64bit jdk 1.6 installer . Can I install java on centos 5.8 32 bit using a 64 bit installer. If so what would be the command to achieve the same.
TIA.
No you can't because a 32 bits OS doesn't provide 64 bits support. The reverse is true though, you can install a 32 bits program on a 64 bits Linux.
Specifically in the case of Java program though, except for those programs that require huge heaps you should be able to get the to run on both a 32 bits or 64 bits JDK, so it's worth a try to install the 32 bits JDK and try to execute the application.
Simply, no you can't. To run a 64-bit application, you need an OS that supports 64-bit apps, and a 32-bit OS does not do this.
I had a windows vista machine with much lower specs and Netbeans6.8+Scala2.8 worked fine.
old specs: Vista home premium, 4 GB ram, 320 gb hdd 5400 rpm, java 1.6.0.16
new specs: Win 7 professional, 8 GB ram, 250 gb ssd, java 1.6.0.21
The compilation on the new machine is much slower. Java and javaw take up to 95% cpu during compile.
any ideas how this can be fixed?
I am not able to upgrade NB due to some restrictions.
All I can say is try to ask to see if you can get a newer version of Netbeans. Netbeans 6.9.1 has many performance improvements, with Netbeans Dev being faster. You can make an argument saying that the slow performance is impacting your work.
Really the only other things you can do is disable modules you don't need which might free up some resources.
With that much memory you could try to run NB on Vista or Linux in a VirtualBox instance.
Answering my own question since I found the cause:
The reason (don't know if it applies to other Netbeans versions apart from 6.8):
the new PC runs 64 bit Windows 7 and a 64 bit JDK (I forgot to mention this in my question)
the old PC rund 32 bit Vista and 32 bit JDK
Netbeans currently runs in 32 bit mode only, so when on the new PC, it was an issue with running the 64 bit JVM from Netbeans. This problem is discussed here:
Issues with running 64 bit JDK under Netbeans
The easiest solution for me was to install a 32 bit JDK and force Netbeans to use it as the default platform (required modifying netbeans.conf). Additionally, -J-Xmx512m
did not work on the 32-bit JDK, so I had to set it to -J-Xmx400m
The following stackoverflow link was also helpful in figuring out the optimal settings:
