Hi Vutha,
Are you looking for instructions on collecting a core file, created by a failing userland process, or do you want to collect kernel crashdump files ?
You can look at the output of the coreadm command to find out what file is stored in which location.
What to collect is nicely described in [url https://supporthtml.oracle.com/ep/faces/secure/km/DocumentDisplay.jspx?id=1010911.1]What to send to Oracle Sun after a system panic and/or unexpected reboot (Doc ID 1010911.1).
Did you know we have two community categories in My Oracle Support, where you also can post your questions ? Have a look at [url https://communities.oracle.com/portal/server.pt/community/sun_sparc_enterprise_servers/447]Sun SPARC Enterprise Servers and [url https://communities.oracle.com/portal/server.pt/community/oracle_sun_technologies/388] Oracle Sun Technologies .
Hope this helps,
Kind regards,

Newbie: How To find Core Dump files on Unix?! URGENT!

Hi, i would like to know on How To find Core Dump files on Unix?!
I know they should be found in /usr/sap/<SYSTEM-ID>/<INSTANZ>/work
but there are no "core" files and also in tmp is nothing unusual but disk space is totally full.
So how to find the big files which i could delete to make system running again?!
can someone provide me with some infos?!
br

1. which user i should use to search and destroy?! root-user or SYSID-User?!
Always use the user with the least permissions to do the job, don't use root if your sidadm can do it. If you want to find / delete SAP files use sidadm.
2. I found no core files and the harddisk is still 100% full, what files might also cause this problem
In your first post you wrote that /usr/sap/SID/INST/work dir is full, it is most likely that some trace files got to large. Check for files like dev_*, dew_w0 for example is the trace file of work process 0, dev_disp is the trace of the dispatcher and so on. You either have to increase the size of the filesystem, or find the cause for the growing file. It can be due to an increased trace level.
3. What on database-side could cause this problems?! can i search for sth here.
This does not look like a database issue so far.
4. i was unable to use the given scripts (noob!), what can i do else?!
Which one, please post what you typed and the error you got.
Best regards, Michael

How to view database core dump file

I have an Oracle server on windows 2000. Now, I found the oracle server will produce a core dump file in ..\cdump directory. But this file is only a system memory image, so it's hard to analysis the core dump reason, could you tell me how to view this file? thanks

There's no much useful information for you too see. You can create a SR with Oracle support and upload file if you want to investigate the cause of core dump. also check if there's any errors in your alert<SID>.log and core_dump_dest

AIX core dump file,

Hi
In AIX core dump file, we got this message
'SOFTWARE PROGRAM ABNORMALLY TERMINATED'CORE FILE NAME
/scclive/oracle/inst/apps/SCC_ebsprod/ora/10.1.2/forms/core
PROGRAM NAME
frmweb
We are getting these errors frequently when there was some network issue between our server and PDC. That why oracle application server is hanging and we had to bounce for resolving the issue. Can anybody help how to resolve permanently from AIX point of view?
Regards
Ateeq

Hi
1)In which way the PDC is connected to your EBIZ system?
No we are using hostfile. 2)If point 1 is correct then u should solve the network issue as the forms sessions are hanging coz of network issue OR If point 1 is correct then you must update the EBIZ system hostfile with the fully qualified domain name and remove DNS server for the EBIZ system to solve this issue.
We do have fully qualified domanin name in hostfile.As well as using DNS server also.Regards

Why my core dump file is "???? " in main process in solaris 10

why my core dump file is "???? ?" in main process in solaris 10?
and called funtion is ok , can see the name and address!
this problem is only occurent in solaris 10, not in solaris 8
for exampel, pstacking core file is :
?????(0x0034x,......)----------this function in main process
ACE_Rector::svc()(0xff3e........)this is called function

If i recall correctly its because the binary called a function (in a library for instance) which pstack can not resolve.

Collect core dumps in a Linux vmware

Hi,
we have a Linux installed using VMware, and are using this for teaching.
Unfortunately collect core dumps on every executable, on some installtions.
We tried studio 12 and express and different Linux distributions.
Scientific Linux 5.1 and Ubuntu 8.0.4 both don't work however OpenSuse10.3 works.
The curious thing is collect works fine on Scientific Linux and Ubuntu 8.0.4 if not installed in a VMware.
I can provide an example VMware image if that is of interest.
Did anyone encounter similar problems or has a solution for this?
(we would like to use Ubuntu or Scientific Linux)
best regards,
Samuel

VMWare is not a supported platform for Sun Studio Performance Tools, at least
not yet. We are planning to add support sometime soon, but it's not there yet.
Can you send me more information about the failure? We currently
do not even have a test environment with VMWare.
Thanks,

Revoe core dump files from cdump directory

Hi,
I have lot of core dump files exist in cdump directory of 5 GB size. Latest core dump is feb 27 2008.
Can I safely remove all core dump files now, it is production instance 10.2.0.1 running on HP-UX.
Please suggest. I

No problem, a core dump means that the memory of the process was dumped in a file 'core' on the file system because of an exceptional condition similar to the internal error ORA-600, however, the big difference is that the kernel did not anticipate the error.

[Solved] Systemd: how to disable core dumps on application crashes?

Hi,
I'm sorry if this is the wrong forum, but I just couldn't find a place that's really suitable for such a question.
I have a really annoying problem with systemd: I'm developing software, which sometimes crashes. And when it crashes, I sometimes want to examine core dumps.
The problem is that systemd seems to force coredumps, but saves them in some kind of obscure internal storage, where I don't have a clue about how to extract them from.
The only hint that I could find was http://lists.freedesktop.org/archives/s … 04643.html which isn't really helpful.
The problem is that systemd installs its coredump handler on boot:
[root@neptun ~]# cat /proc/sys/kernel/core_pattern
|/usr/lib/systemd/systemd-coredump %p %u %g %s %t %e
Is there any way to disable this? I don't want core dumps to be generated unless I need them. Just clearing that file on boot seems too hackish for me, does anybody know if there is a systemd
configuration option to turn coredumps off?
Cheers,
andr3as

The .conf file was recently renamed so the symlink must be called different as well. But I found it needs to contain something to actually overload systemd's default
# echo kernel.core_pattern= > /etc/sysctl.d/50-coredump.conf
# /lib/systemd/systemd-sysctl
# cat /proc/sys/kernel/core_pattern # should be empty

Redirect core dump file

This seems like a fairly simple problem, but I cannot seem to find it in any searches...
How can I set the core (or heap) dump directory to "/usr/scratch" instead of the current directory. I running 1.4.2 for now.
Thanks for any help!

Hi, Im not familiar with heap dumps so i apologize if this isnt helpful...
http://blogs.sun.com/roller/page/alanb?entry=heap_dumps_are_back_with
If you don't want big dump files in the application working directory then the HeapDumpPath option can be used to specify an alternative location - for example -XX:HeapDumpPath=/disk2/dumps will cause the heap dump to be generated in the /disk2/dumps directory.
https://hat.dev.java.net/doc/README.html
For example, to run the program Main and generate a binary heap profile in the file dump.hprof, use the following command:
java -Xrunhprof:file=dump.hprof,format=b Main
also:
http://www.hp.com/products1/unix/java/infolibrary/prog_guide/hotspot.html
-XX:+HeapDumpOnOutOfMemory
The HeapDumpOnOutOfMemory command line option causes the JVM to dump a snapshot of the Java heap when an Out Of Memory error condition has been reached. The heap dump format generated by HeapDumpOnOutOfMemory is in hprof binary format, and is written to filename java_pid<pid>_<.hprof in the current working directory. The option -XX:HeapDumpPath=<file>_< can be used to specify the dump filename or the directory where the dump file is created. Running with application with -XX:+HeapDumpOnOutOfMemoryError does not impact performance. Please note the following known issue: The HeapDumpOnOutOfMemory option does not work with the low-pause collector (-XX:+UseConcMarkSweepGC). This option is available starting with the 1.4.2.11 and 1.5.0.04 releases.

How to collect to different files into one message

Hi,
I have the following scenario:
Two (5Mb) Files with different file structures each ->
XI (transform and generate a single structure record) ->
Insert a record in a DB for each new record generated
Let suppose file1 has order headers - one order per line -and file2 has the corresponding order items - one item per line, e.g;
File 1
OrderNr Description
1        A
2        B
3        C
File 2
OrderNr   ItemNr   MaterialCode ....
1         1        111
1         2        222
1         3        555
2         1        888
2         2        777
3         1        111
Imagine I want to insert a record in the database for
each order/item like this
OrderNr ItemNr Description MaterialCode .....
1        1      A           111
1        2      A           222
1        3      A           555
My real scenario is a little more complicated but never mind for now.
I need to collect the two different files with two different file structures into the same message. Although I have read about the subject I am not sure about how to do it using BPM because there isn't any field I could use to correlate file1 with file2 - I can only correlate a record of file1 with several records of file2. I simply know that the two files will be available in a specific directory once a day at 06:00AM.
First question is:
How can I collect the two messages originating each from a different file into only one message with two different subtypes one for each file structure?
Because my background is ABAP I could do it with a workaround for temporarily storing the info from each file into database tables in XI and then correlate the info from the two files to generate a single message.
Like this
File1 -> XI -> INSERT DATA XI ZDB1 (via ABAP Proxy or RFC)
File2 -> XI -> INSERT DATA XI ZDB2 (via ABAP Proxy or RFC)
Them I could use an event to check when the two tables have all the data from both files. I could then combine the data from the two tables and start another integration process like this
XI SERVER (ABAP Proxy) -> XI Integration Server -> Third-party (JDBC)
But this way I would have to code the hole data conversion which is not a good idea from the perspective of XI (EAI/Broker).
Maybe I sould use BPM. But how?
Futhermore:
Is BPM performant enough (we are talking about files with thousand of records)?
Thanks in advance
Diz

Hi,
for N:1 Multimapping you have to use BPM.
After going through this weblog you will be quite familiar with how to collect 2 messages into one message.
/people/pooja.pandey/blog/2005/07/27/idocs-multiple-types-collection-in-bpm
Steps:
1. Create a abstract/ inbound / outbound interfaces. (in your case 3 /1/2).
2. Perform 2:1 Multimapping.
You can specify more than one message in either side.
Just go to message tab in MM.
3. Now follow the blog and you will get a output in the form of abstract interface.
4. Define JDBC reciever Channel as usual.
Your database will be updated.
Just try this out.

How to find a dump file is taken using norma exp or expdp

Hi All,
How to find out whether a dump file is taken using the conventional exp or using the expdp utility?
OS: HPUX
DB: 10.2.0.4

Hi ,
I go with Helios's reply. We cannot just predict if it was taken my expdp or exp.
Since your DB version is 10 , both could be possible.
The simplest way would be : just run the imp , if it throws error , then its created through expdp.
because dump from expdp cannot be used with imp and vice versa. So that could help you find..
else , try to get the syntax by which the dump was created.
If you have any doubts , wait for experts to reply.

How import 10g,11g dump file in oracle 9 and oracle 8

Dear all
I import dump file exported from oracle 9 to oracle 10g and 11g now i want exported dump file from oracle 10g/11g to import in oracle 9 (lower version).
How said job will be done.
Thanks

I've already tried your method, but it fails when you import the dmp exported from lower version.
To import Oracle 11g user to Oracle 10g, the following method works fine:
It is assumed that both 11g and 10g servers are on same LAN.
Make sure that 11g sqlplus connects to your 10g server.
Step 1. Export the 11g user from 11g machine.
Step 2.Import the dmp file created in step 1 into 10g server from 11g machine itself.
The 11g exp/import utility should be used for both export and import operations.
Only source and destination servers will be different.
