I have seen some references to this being an on solaris10. Is this an issue on linux IA-64 as well?

Please open a ticket with Oracle Support and provide them with the core file for analysis.

Top shows VM usage is 255G - 1.5.0_08 (R27.1.0) crash on Linux IA64

Hi,
We are running a tomcat process using Jrockit 1.5.0_08 on Linux IA64. The process keeps crashing after a couple of days. (I pasted the dump at the end of the post)
I found something wierd when I monitored the process to validate if the process crashes due to OutOfVM. Just before the process crashed "top" command shows the VM usage of the process is 255G.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
26298 pcadm8 16 0 255g 1.7g 59m D 0.0 21.8 0:16.10 java
ls command shows that the core file generated is 255G, but when I use 'ls -shlart' the output is
1.8G -rw------- 1 pcadm8 pcadm8 255G 5ŒŽ 28 19:07 core-java.26298
Linux OS: RHEL AS4 Kernel
Kernel: 2.6.9-5.EL
glibc: 2.3.4-2
The language/codepage on the machine is Japanese.
The crash happened earlier similarly, I found from dump file that Code Generation thread failed, so I added -XnoOpt, but this has not solved the problem still.
Any help is appreciated,
Thanks,
Krishna Rajappa
PS: Please note I have pasted entire dump contents - the stack trace was empty.

Hello Krishna,
There are known issues in the Linux kernel on early versions of Red Hat 4.0 for Itanium. I suggest that you start by upgrading that to a recent Update level. RHEL 4.0 Update 2 is the absolute minimum requirement.
You may also want to consider upgrading your JRockit version. If you´have a suppotr contract, you can get one from the BEA/Oracle support web sites, or bundled as part of JRockit Mission Control here:

Instantclient-odbc-linux-ia64-10.2.0.1-20051213.zip

Hi,
One month ago in OTN there was a Link to the file
instantclient-odbc-linux-ia64-10.2.0.1-20051213.zip (26,662 bytes) (cksum -3623609500).
I found that link under http://www.oracle.com/technology/tech/oci/instantclient/instantclient.html
Platform: Linux Itanium
-> Version 10.2.0.1
Now it has disappeared. I really need that file. Please offer that link again!
Best regards
Ralf

Nov 2, 2006. I'm adding this hoping it helps someone else in the future. I asked this question to Oracle Support. Their response:
QUESTION
========
Customer is planning to upgrade from 10.2.0.1 and 10.2.0.2. Customer is running ASM ,so customer is asking do they need to apply Patch 4547817 on Database Home or to ASM home as well.
ANSWER
======
No. You dont need to apply Patch 4547817 on ASM home.You should apply Patch 4547817 on Database Home only. You dont need to apply Patch to ASM home. You are going to upgrade database from 10.2.0.1 to 10.2.0.2. Database can be on 10.2.0.1 or 10.2.0.2 but ASM cant be.

How to run a JRockit process in the background(Linux ia64)

Hello,
I am trying to start a JRockit process 1.4.2 (with a Java app) from an SSH console and make it keep running after I log out. This is on Redhat Enterprise Linux WS 4 with Itanium II processor (ia64).
The obvious thing such as
java <options> <class> &
or even
nohup java <options> <class> &
Do not work and the process terminates when I log out.
Is there a recommended method or a facility to run JRockit in the background as a service/daemon? Does JRockit has switch similar to â€“Xrs of Sunâ€™s JVM?
Starting the process on system boot and having to reboot the system to restart it are not acceptable.
Any help will be greatly appreciated.
Thanks,
Zapta

Zapta did get an answer. You may have missed it if you're using nntp to access the forums, since many newsreaders don't track threads that change the subject. I recommende the using the web UI at dev2dev.bea.com.
Anyway - Use "-Xnohup" with older versions of JRockit. In recent JRockit versions, "-Xrs" works as well, since we seen problems with people hardcoding that flag into various applications launchers (Tomcat for one).
Cheers!

J2sdk installation problem on 64 bit linux machine

Hi
when i install the j2sdk then it gives the following error.:
/j2sdk-1_4_2_13-linux-ia64.bin: line 425: ./install.sfx.8624: cannot
execute binary file
PLEASE SUGGEST ANY SOLUTION
Thanks

IA64 is the Itanium architecture. You probably don't have such a machine (if you did, you'd definitely know it).
If indeed you are running Linux on a 64bit machine chances are pretty high, that you are using a processor that's running the the AMD64 architecture (also called EM64T, x86-64, IA32e, ...). AFAIK only 1.5 is available for that architecture.

JDK 1.4.2 for Linux Redhat 5 on x86_64 (amd64) ?

Hi,
i need to install a Netweaver 2004s on a Redhat 5 x86_64 system. But I can't find a source for downloading the correct JDK or SDK version.
OSS 941595 provides a link to java.sun.com with a special package for SAP-software, but it provides only solaris and windows packages. On java.sun.com it looks like there is no package for linux x86_64 previous java 1.5.x.
I found a SAP-presentation, on it they refer to an IBM-rpm java package which should work. But were to download it? On ibm.com I could not find it...
Thanks for any hints!
Roland

hi,
thanks for your answer!
But there they provide:
- j2sdk-1_4_2_12-linux-i586.bin --> this is 32bit
- j2sdk-1_4_2_12-linux-ia64.bin --> this is IA64 (also called "Itanium"), which is NOT the same as x86_64 (also called Amd64 or Intel64)
- and some solaris-packages, which I also can not use
The problem is to find a package for Linux x86_64. I need this platform to be able to use more than 4gb memory...

Linux install : 1st stage failure.

Hello,
I'm trying to install Oracle 9.2.0.x in my Mandrake box( 2.4.19 ).
Having uncompressed and doing a 'cpio' created the three Disk's, I go to Disk1 and run runInstaller.
The environment variables are set correctly. But when I run it errors out "./runInstaller: line 58: ./runInstaller: cannot execute binary file"
Why is that... I hope the binary can't be corrupted, as it was created right out of that 'cpio'. There is no permission problem either.
Any guidance would help. Thanks.

The most recent version 9.2.0.2 seems to be only for 64 bit chips. This Linux version is for the IA64 a.k.a. Itanium chip. It will not run on the i386 architecture.
Make sure you download version 9.2.0.1.
This is how the two versions are listed:
Oracle9i Database Release 2 Enterprise/Standard Edition for Linux/IA64, Release 2 (v9.2.0.2)

Thank you of your reply,
but I am confuse which one I need to refer?
My processor is Pentium 4 and my VGA card is MSI FX5200-T128.
So which "Graphics Drivers" I need? Linux IA32 or Linux IA64?
And which "nForce Drivers"?
Should I need to upgrade my BIOS before I install the driver?
My motherbroad series is 875P Neo Series.
can please guide how to upgrade by manually (not LiveUpdate).
At tne meantime, I found another VGA driver from "www.viaarena.com/?PageID=296"
but is only provide for "AS IS" type. May I know is "MSI FX5200-T128" as same as "AS IS" type?

Download error w/IA64 9202 files

Yesterday I downloaded the
Oracle9i Database Release 2 Enterprise Edition for Linux/IA64, Release 2 (v9.2.0.2)
And when I ran cpio on disk3, I found that it contained the same content as disk1, it tried to over lay the Disk1 directory.. I am downloading disk3 again.

This time disk3 was really disk3. I used mozilla on HP Itaium machines to download both times and the only change was to the directory to receive the files.
I seem to be good now.

AttachCurrentThread SEGV linux Itanium 64 Java 6

I have a Java application which is core dumping. This application has a JNI component. The JNI component tries to attach a native thread to VM to do a call back to Java method. SEGC occurs while doing AttachCurrentThread. Here is a code snippet.
JNIEnv *env;
JavaVM *jvm_local;
jsize nVMs;
/* Get the JNI Env from the JVM */
/* JNI_GetCreatedJavaVMs(JavaVM **vmBuf, jsize bufLen, jsize nVMs); /
if(JNI_GetCreatedJavaVMs(&jvm_local, 1, &nVMs) != JNI_OK) return -1;
(*jvm_local)->AttachCurrentThread(jvm_local, (void **)&env, NULL);

I see Exceptions::throw_stack_overflow_exception (). Is this a "reliable" indication that there was stack overflow? Here is the VM info:

Pointer bugs do not necessarily produce immediate errors. They can cause the app to fail in unexpected ways almost anywhere after the point where the bug occurred. A common indicator of this is if the code changes or the execution through the code changes then a different bug (location) occurs.I suspected that "stack overflow" is not a good indicator (especially based on some of your older posts). I do not understand what you mean by -- That is followed by a misuse of an API (which is going to end up resolving to a pointer error too.). I am using the VM pointer and am attaching a native thread to it to call back into Java layer. Can you please elaborate on the misuse?

Linux redhat 8

hi all
does oracle Oracle9i Enterprise Edition for Linux/IA64, Release 2 (v9.2.0.2) which is the latest version of oracle database can work with redhat linux 8 . in case if it does not work then could you please guid me which version of oracle database do I need to get to work with linux redhat 8 ?
thanks

I think it is but check metalink.oracle.com => Certify and avalaibility to be certain.

Installation of Oracle 9i (9.2.0.2) on Linux

Hi there, I downloaded the latest release of Linux/IA64 9.2.0.2 DB. When run ./runInstaller, I got error with "./runInstaller : cannot execute binary file". Is that I downloaded the wrong verions or ..? Please advice.. thanx..
Regards,

sorry guys... I know I downloaded the wrong version for normal intel pc.. pls ignore this..thanx..

SAP, Itanium, Linux and virtualization ...

If you've been there, these keywords without Linux usually lead to HP-UX and HP VSE OE with Integrity VM. But, if you try to find legitimate and practical alternative, it turns out that RHEL with Xen is the only good choice.
I have several system copies running on RHEL5.4 Linux with Xen virtualization platform, most of them are SAP ERP based with Oracle 10.2.0.4, ECC 6.0 EhP3, both on HVM Windows Server 2003 guest systems and on PV RHEL5.4 guest systems, few IDES systems, one with NW7.0 and Portal. All this is running on HP Integrity / Itanium 2 hardware (BL870c), and FC SAN, HP EVA 5000 and EVA 8400 is used for storage. What I'm interested here above all is to hear if there is anybody out there having some similar story (SAP, Itanium, and virtualization) ? Please, speak out if you are listening ...
I have some documents prepared and in preparation with details (I will put it here or in blog if there is interest), but for now just in short: systems are quite good, performance could be compared with some physical systems and production servers, but above all it is very stable. We also use VMWare for x86/x64 in our company, so I am able to compare these two platforms. There are many pros and cons, but I think that both offer good solutions. One of the main conclusions is that Xen on Itanium compared to HP-UX offers similar if not even better performance (that is, at least until HP finally gets implemented AVIO for HVM Windows guests), and if you are not in need of some high-end features (including live migration), Xen is better. There were some bumps on the road, though - Oracle showed me a bug (some workaround is available, though), but the biggest of them all is that RHEL decided to abandon support for Itanium in RHEL 6 ... SLES is a good option, but it is not supported by SAP at the moment. Any comments, questions, hints, insights, advice ?
ZP.

I ment, not just hardware vendors (Oracle, Microsoft, SAP, ...) - IBM had the most performant system based on SAPS and benchmarks for long time (AFAIK, if it didn't change in the mean time, Oracle also made a competition, I don't know if anyone took the claim), but it had even worse cost/performance ratio than HP Integrity. If you want high end performance, Itanium can give you solid single-threaded horse power that x86 couldn't offer (again, AFAIK), and this is very important for databases and some business systems - it is not always about parallelization and number of concurrent users per system.

Because of the nature of it being an EPIC processor all the optimization logic must be put into the compiler. I guess, the open source community will not be able (just due to the lack of manpower and knowledge) to make gcc as good as the HP-UX aCC compilers.

Unfortunately or not, my management decided to move on with Itanium (but unfortunately for sure they decided years ago to go into production with Windows). You are right up to some point - Itanium is EPIC, but it is not just for scientific and FP, why would they've been sold successfully as platform for database servers for years ? There are IA64 CPUs with additional FPU and cache, and there are different versions and platforms - what did you exactly compare ? Generally it's still not that clear IMO. And here comes my favourite anegdote about Itanium raw performance: while doing an Oracle 10g patch (CPUJan2009 bundle, I think or something like that), carelessly for some reason (I usually don't do it that way, of course) I haven't read the patch README and I have omitted to do additional view compiling by habit (many patches/patchsets do not need it beside the usual compiling). Production database node has two dual 1.1GHz processor modules and 8 or 16G of RAM at that time (mx2 modules, let's say it is like 2 CPUs with dual cores), and the moment I have had database ready for use I have concurrently read that I need additional compiling which needs about 30 minutes for average database with 2000 objects by internal Oracle benchmarking/testing. I have sighed, did query and saw three to four times more objects in my database than stated in the README manual, and started swearing in myself about complicated corporate procedures and flows about informing users, system availability, internal QA, etc. So, I decided to put system back down with my teeth strongly clenched together and started these two scripts on production system (not the usual situation, I repeat). It lasted not more than 5 minutes ! I didn't have to follow all the strict QA procedures, inform users, and so on ...

Stack size for native thread attaching to JVM

All:
I have a native thread (see below, FailoverCallbackThread) that attaches to the JVM and does a Java call through JNI. The stack size for the native thread is 256KB.

This causes stack overflow in Oracle JRockit JVM. (It does not cause overflow with Oracle Sun JDK.) Is there a recommended stack size for this use case for JRockit? Is there a way to compute it roughly?

How do I found default heap size, stack size for the
thread, number of threads per jvm/process supported ?The threads is OS, OS install and jvm version specific. That information is also not useful. If you create the maximum number of threads that your application can create you will run out of memory. Threads require memory. And it is unlikely to run very well either.
The default heap size and stack size are documented in the javadocs that explain the tools that come with the sun jdk.
and how the above things will vary for each OS and how
do I found ? Threads vary by OS, and OS install. The others do not (at least not with the sun jvm.)
If I get "OutOfMemoryError: Unable to create new native thread" Most of the time it indicates a design problem in your code. At the very lease, you should consider using a thread pool instead.
I found in one forum, in linux you can create maximum
of 894 threads. Is it true ?Seems high since in linux each thread is a new process, but it could be.
