Dump file size in exp
Hi all,
i exported the database having around 900 mb size using parameters
exp file=full.dmp log=full.log full=y direct=y
but the exported file size is 137mb.
why this file size is small. even it compressed it has to be at least 70%.
does this file hold entire data of the database.
please let me know.
thank you!
Hi,
Is the 900 MB size the allocated size or the actual database size?
select (select sum(bytes)/1024/1024 from dba_data_files)+
(select sum(bytes)/1024/1024 from dba_temp_files) "Size in MB" from dual;
select sum(bytes/1024/1024) from dba_free_space;
Anyway since the size of the dumpfile is small, you can try to import it in a test environment first and verify whether all the schema objects are matching.
Thanks and Regards,
Rajesh K.

*** DUMP FILE SIZE IS LIMITED TO 0 BYTES ***
I always get a trace file with
*** DUMP FILE SIZE IS LIMITED TO 0 BYTES ***Do you have a cleardown script on your dump directory (probably user dump) that deletes dumps while sessions are still running. You get a trace in background dump directory (pmon, I think) that gives your message when that happens.
OTOH it might be something completely different. -
Hi,
on 10g R2, on AIX 6.1 I use the following EXPDP :
expdp system@DB SCHEMAS=USER1 DIRECTORY=dpump_dir1 DUMPFILE=exp_USER Logfile=log_expdpuserwhich results in a 3Gb dump file. Is there any option to decrease dump file size ?
I saw in documentation :
COMPRESSION=(METADATA_ONLY | NONE)
but it seams to me that COMPRESSION=METADATA_ONLY is already used since it is default value and COMPRESSION=NONE can not reduce the size.
Thank you.You can use FILESIZE parameter. and specify multilple dumps.

Otherwise you can use RMAN Compressed backup sets.

Estimate the Import Time by viewing the DUMP File Size
Its very generic question and I know it can varry from DB to DB.
But is there any standard way that we can Estimate the Oracle dump import time by viewing the Export Dump file size ?Well, it's going to be vaguely linear, in that it probably takes about twice as long to load a 2 GB dump file as to load a 1 GB dump file, all else being equal. Of course, all things rarely are equal.
For example,
- Since only index DDL is stored in the dump file, dumps from systems with a lot of indexes will take longer to load than dumps from systems with few indexes, all else being equal.
- Doing a direct path load will generally be more efficient than doing a conventional path load

Heap dump file size vs heap size
Hi,
I'd like to clarify my doubts.
At the moment we're analyzing Sun JVM heap dumps from Solaris platform.
Observation is that heap dump file is around 1,1GB while after loading to SAP Memory Analyzer it displays statistics: "Heap: 193,656,968" which as I understood is size of heap.
After I run:
jmap -heap <PID>
I get following information:
using thread-local object allocation
Parallel GC with 8 thread(s)
Heap Configuration:
MinHeapFreeRatio = 40
MaxHeapFreeRatio = 70
MaxHeapSize = 3221225472 (3072.0MB)
NewSize = 2228224 (2.125MB)
MaxNewSize = 4294901760 (4095.9375MB)
OldSize = 1441792 (1.375MB)
NewRatio = 2
SurvivorRatio = 32
PermSize = 16777216 (16.0MB)
MaxPermSize = 67108864 (64.0MB)
Heap Usage:
PS Young Generation

From Space:

So I'm just wondering what is this "Heap" in Statistic Information field visible in SAP Memory Analyzer.
When I go to Dominator Tree view, I look at Retained Heap column and I see that they roughly sum up to 193,656,968.
Could someone put some more light on it?
thanks
MichalHi Michal,
that looks indeed very odd. First, let me ask which version do you use? We had a problem in the past where classes loaded by the system class loader were not marked as garbage collection roots and hence were removed. This problem is fixed in the current version (1.1). If it is version 1.1, then I would love to have a look at the heap dump and find out if it is us.
Having said that, this is what we do: After parsing the heap dump, we remove objects which are not reachable from garbage collection roots. This is necessary, because the heap dump can contain garbage. For example, the mark-sweep-compact of the old/perm generation leaves some dead space in the form of int arrays or java.lang.Object to win time during the compacting phase: by leaving behind dead objects, not every live object has to be moved which means not every object needs a new address. This is the kind of garbage we remove.
Of course, we do not remove objects kept alive only by weak or soft references. To see what memory is kept alive only through weak or soft references, one can run the "Soft Reference Statistics" from the menu.
Kind regards,
- Andreas.

Dump File Size vs Database Table Size
Hi all!
Hope you're all well. If Datapump estimates that 18 million records will produce a 2.5GB dumpfile, does this mean that 2.5GB will also be consumed on the database table when this dump file is imported into a database?
Many thanks in advance!
Regards
ACdoes this mean that 2.5GB will also be consumed on the database table when this dump file is imported into a database?No since the size after import depends on various factors like block size, block storage parameters etc.

What is the dump file size limit?
Hello all,
Can somebody tell me what is the maximum size of the dump file created by export utility in Oracle? Is there any maximum size applicable to dump file?
Thanks in advance
HimanshuHi,
Later Oracle 8.1.6, is no more Oracle limitation on dump file, with restriction 2Gb for full 32-bits OS (32-bit with 32-bit files). The maximum value that can be stored in a file is dependent on your operating system.

i am exporting one schema.The total size of all the objects in that schema is 70GB.When i perform export on that schema the the size of the dmp file will be 70GB or less?Can any there out to help me.
OS:Solaris
DB Version:9.2.0.6
Thank you..Hi,
When you do an export, you are only exporting the data. Other objects, such as indexes are only exported as a description so take up virtually no space. A general rule of thumb is to work out the actual amount of used data blocks you have, remembering that tables can have allocated space that is empty, and this will give you a size that is probably slightly larger than the export, maybe by about 10%. Also, export files are highly compressible. So if you need to save space, you will usually get about 80 ~ 90% compression ratios.

Now, from this exp_backup.dmp file, I just want to find out the list of tables, which got exported.
I don't have access to the Parameter file used for exporting data. Please share your views, suggestions, thank you.Hi,
did you try to get the details logfile created for your export dump ?

Hi,
I have to analyse large heap dump file (3.6GB) from production environment. However if open it in eclipse mat, it is giving OutOfMemoryError. I tried to increase eclipse workbench java heap size as well. But it doesnt help. I also tried with visualVM as well. Can we split the heap dump file into small size? Or is there any way to set max heap dump file size for jvm options so that we collect reasonable size of heap dumps.
Thanks,
PrasadHi, Prasad
Have you tried open in 64-bit mat on a 64-bit platform with large heap size and CMS gc policy in MemoryAnalyzer.ini file ? the mat is good toolkit on analysing java heapdump file, if it cann't works, you can try Memory Dump Diagnostic for Java(MDD4J) in 64-bit IBM Support Assistant with large heap size. -
Hi q all.
maybe this question already many times asked, but I've a task to develop an app that parses a dump file (created by exp-tool) and show to user the version, all users and his objects that were exported. I've already build the app that reads the log, created by "imp show=y log=... " and interprets that content.
Maybe there are some other posibilities or ideas.
Please don't ask me for the reason of that task.

I have a dump file made with exp command. It is a schema dump.
I would like to extract the ddl of the trigger. how can I do this?
I tried with imp + indexfile
but I the file created there are no triggers.Why not use dbms_metadata.get_ddl('TRIGGER','<TRIGGER_NAME') to generate the ddl and create.

I read an article on EXPORT of dump file cannot over the limit of 2Gig. This is because prior to 8.1.3 there is no large file support for Oracle Import, Export, or SQL*Loader utilties.
How bout the current version? 9i or 10g? Can the exp dump file be larger than 2G?Under AIX Unix, there is a fsize parameter for every user in /etc/security/limits file. if fsize = -1 then user will have authority to create any file size. But to do this change, you should have root access under Unix enviroment.

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: 10.2.0.4Hi ,
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.
