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
AC

does 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.

How can I list used database/table size resp user space ? Compression after

How can I list used + maximum tablespace/database/table size of an Oracle database ?
How can I list the space used currently by a user resp. his tables+indizes ?
By the way: If I delete a user or table from an Oracle database installation: are then only the entires deleted
or is the space released as well ?
In otherwords: After I deleted a user resp. table is it recommended to do something like a "compress" similarly to Outlook
or other eMail clients to shrink really the occupied space on hard disc ?

I hope this helps you
select df.tablespace_name "Tablespace",
totalusedspace "Used MB",
(df.totalspace - tu.totalusedspace) "Free MB",
df.totalspace "Total MB",
round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace))
"Pct. Free"

Index size increases than table size

Hi All,
Let me know what are the possible reasons for index size greater than the table size and in some cases index size smaller than table size . ASAP
Thanks in advance
sherief

hi,
The size of a index depends how inserts and deletes occur.
With sequential indexes, when records are deleted randomly the space will not be reused as all inserts are in the leading leaf block.
When all the records in a leaf blocks have been deleted then leaf block is freed (put on index freelist) for reuse reducing the overall percentage of free space.
This means that if you are deleting aged sequence records at the same rate as you are inserting, then the number of leaf blocks will stay approx constant with a constant low percentage of free space. In this case it is most probably hardly ever worth rebuilding the index.
With records being deleted randomly then, the inefficiency of the index depends on how the index is used.
If numerous full index (or range) scans are being done then it should be re-built to reduce the leaf blocks read. This should be done before it significantly affects the performance of the system.
If index access’s are being done then it only needs to be rebuilt to stop the branch depth increasing or to recover the unused space
here is a exemple how index size can become larger than table size:

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the rows? Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?
Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

The Oracle documentation has a good overview of the options available
Generating XML Data from the Database
Without knowing your version, I just picked 11.2, so you made need to look for that chapter in the documentation for your version to find applicable information.
You can also find some information in XML DB FAQ

Migrate sql server dump file to Oracle database on a network

I have a sql server dump file provided to me by DBA's. I have to migrate this dump file to Oracle database on a network. Please suggest me the steps to do this.

That would be a text file with around 100 records. I have migrate those records to oracle database. The firewall constraints doesn't allow me to create a link to that database. Will Migration workbench would be apt for this case. How can i capture the database offline in this case ?
regardless of the tool/technique you use, those bits have to get from machine running sqlserver to the machine running Oracle. Either over the network (through the firewall) or via 'sneakernet.' What, exactly, are the firewall constraints?
If the export is a simple text file (character delimited fields? fixed length fields?) and only 100 records ... Migration Workbench may be overkill, perhaps a simple sqlldr job. But you still have to get the bits from 'there' to 'here'.
============================================================================
BTW, it would be really helpful if you would go to your profile and give yourself a recognizable name. It doesn't have to be your real name, just something that looks like a real name. Who says my name is really Ed Stevens? But at least when people see that on a message they have a recognizable identity. Unlike the system generated name of 'ed0f625b-6857-4956-9b66-da280b7cf3a2', which is like going to the pub with a bag over your head.

Index size greated then Table Size

Hi all,
We are running BI7.0 in our environment.
One of the tables' index size is much greated than the table itself. The Details are listed below:
Table Name: RSBERRORLOG
Total Table Size: 141,795,392 KB
Total Index Size: 299,300,576 KB
Index:
F5: Index Size / Allocated Size: 50%
Is there any reason that the index should grow more than Table? If so, would Reorganizing index help and if this can be controlled?
Please letme know on this as I am not very clear on DB much.
Thanks and Regards,
Raghavan

Hi Hari
Its basically degenerated index. You can follow the below steps
1. Delete some entries from RSBERRORLOG.
BI database growing at 1 Gb per day while no data update on ECC
2. Re-organize this table from BRSPACE . Now the size of the table would be very less. I do not remember if this table has a LONG RAW field ( in that case export /import) of this table would be required. ---Basis job
3. Delete and recreate Index on this table
You will gain lot of space.
I assumed you are on Oracle.
More information on reoganization is LINK: [Reorg|TABLE SPACE REORGANIZATION !! QUICK EXPERT INPUTS;

Csv file uploading for database table creation

Hi there,
I'm in the process of making an application that will be able to upload a csv file and create a table based on the same file. As of now, I have managed to make my application upload a csv file into the database. My problem now is to transfer the data in the csv into a table. If there is a function that can do this, please let me know. But as of now, I have tried all that I can but in vain. I would appreciate any assistance rendered as to how I can go about this.
Kind regards,
Lusuntha

hai Lusuntha ,
Go to search forum and type "upload within html db".here u will find the required information ,as well as the code.go for each topic in the search result.

Index size greater than table size

HI ,
While checking the large segments , I came to know that index HZ_PARAM_TAB_N1 is larger than table HZ_PARAM_TAB . I think it's highly fragmented and requires defragmentation . Need your suggestion on the same that how can I collect more information on the same . Providing you more information .

Thanks . I know that rebuild will defragment it . But as I'm on my new site , I was looking for some more supporting information before drafting the mail on the same that it requires re org activity .It's not possible for an index to have the size greater than tables as it contains only 2 columns values + rowid . Whereas tables contains 6 columns .

Importing 9i dump file into 10g database

Hello guys,
i know that 9i import is incompatible with 10g datapump.I want to know how i can move the data from my production database(9i) to the new site(10g) without much hassle.
I don't want to use upgrade because not all objects in 9i is needed in the new version of the application.I just want to export what i need from 9i to a dump file and then reimport it into 10g.
Has imp/exp being deprecated in 10g??
And i know i will get invalid objects,i hope recompilation would solve that.I will start the test next week.Just wanted to confirm.
Thank you
Charles

I don't think Export/Import is deprecated in Oracle 10g but Datapump is mostly used in 10g.
But if in 10g Exp/Imp is deprecated - Still you can have a Oracle 9i Client installation with Exp/Imp and then use imp and connect to a 10g database
Thanks

Is tablespace block size and database block size have different meanings

at the time of database creation we can define database block size
which can not be changed afterwards.while in tablespace we can also
define block size which may be different or same as define block size
at the time of database creation.if it is different block size from
the database creation times then what the actual block size using by oracle database.
can any one explain in detail.
Thanks in Advance
Regards

You can't meaningfully name things when there's nothing to compare and contrast them with. If there is no keep or recycle cache, then whilst I can't stop you saying, 'I only have a default cache'... well, you've really just got a cache. By definition, it's the default, because it's the only thing you've got! Saying it's "the default cache" is simply linguistically redundant!
So if you want to say that, when you set db_nk_cache_size, you are creating a 'default cache for nK blocks', be my guest. But since there's no other bits of nk cache floating around the place (of the same value of n, that is) to be used as an alternate, the designation 'default' is pointless.
Of course, at some point, Oracle may introduce keep and recycle caches for non-standard caches, and then the use of the differentiator 'default' becomes meaningful. But not yet it isn't.
