Logical export backup

LQ = > I exported hr schema with three different option of keyword
CONTENT = ALL,
CONTENT = METADATA_ONLY
AND CONTENT = NONE
1.with keyword CONTENTS= ALL
the size of dmp file was 416KB
2. with keyword CONTENTS=DATA_ONLY
I got size = 216
3.Last with keyword CONTENTS=METADATA_ONLY
Igot size = 316
here , My question is that with the keyword = ALL and keyword DATA_ONLY I have clearly understood
that with "ALL" the dumpfile contents metadata + data of schema such as table etc so size was 416KB.
with data_only the dumpfile only contains object's data so size was 216 KB
but , why with the option of METADATA_ONLY the size was 316 KB..As in metadata it should be
416 - 216 = 200 KB ( ALL - DATA_ONLY = METADATA_ONLY)..This is my assumption..If am wrong that
kindly show me the right concept...
And One more thing I want to say that if there is any internal things is happening please let me know..hope I will be
receiving the answer and the concept behind the space that was used by the schemas with various option...

Hi,
can you please provide me the hint..that how can I find out the size of master table etc..The size of the master table is going to be different for every job. It is a table that Data Pump creates and inserts data into as the export and import jobs are running. If you want to know the final size, then add
keep_master=y
on your expdp or impdp command. Then what I did, was to export just that table and see how big it is.
expdp system/manager schemas=hr ... keep_master=y job_name=foo
expdp system/manager tables=system.foo ...
And one more concept I am eagerly waiting to know from you that during datapump when I used to export the whole database >, there I found the warning / error
ORA-39139: Data Pump does not support XMLSchema objects. TABLE_DATA:"OE"."PURCHASEORDER" will be skipped.
I think that XML schema is not supported by our newly feature of export( datapump)
I have done this by giving the command
expdp directory=test_dir logfile=full_database.log dumpfile=full_database.dmp full=y
Note: but , when the same database was exported through the old feature (exp) , the database full was exported successfully >without any error...
can you please throw some light in this regard...You don't say what version you are on, but I believe that support for xml types was not in 10.1 Data Pump but was in old exp/imp. I also think support for this was added in a later version for Data Pump, but I can't recall the exact versions. If you have documentation, you should look at that.

Apply RMAN archivelogs on export backups

Hello Everyone
We are using the below script for RMAN
run
allocate channel c1 type 'sbt_tape';
backup database plus archivelog;
release channel c1;
So whether we shall be able to apply archivelogs on export backups ? If yes how?
Thanks.

It's impossible to apply archived redo logs (physical backup) after importing a export file (logical backup).
You can only apply archived redo logs to a physical database backup or to a physical or logical standby database (Data Guard feature).
See logical and physical backup definitions:

Export Backup Size is different

Hi Gurus,
We are using Oracle 10G (10.2.0.1.0) on Solaris 10 and we used to take export backup daily basis. While taking export backup using 'exp' then .dmp file size is becoming 30.3 GB where as when we use 'expdp' .dmp file size is 26.1 GB. I've checked both the log files and found no. of tables along with their records are same. so I'm confused why this size difference? and as a result we are not in a position to implement 'expdp'. Can anybody tell me why this size difference and whether can we rely on expdp or not?

Oracle recommends that you use the new Data Pump Export and Import utilities because they support all Oracle Database 10g features
Look at the following documentation:

Daily export backup

Hi,
I have production & DR database of 350gb version 10.2.0.4 on aix 5.3 platform.
In morning time after completion of daily batch, we are taking export backup (by stopping application services till application is not available for users) by using datapump utility which is taking 2 to 2.30 hrs to completes.
After that we have starting the application services and then only application available for users.
This export backup dump we are daily using for restoration on another development server.
Kindly help me, is there any option to avoid export backup time so that it will not affect buisness time.
and also i can do daily restoration on development server.
Please help.
Regards,

you can use STREAMS.
If certain schema/objects you can use MViews.

How to ZIP Oracle Datapump export backup file

Hello All,
My customer is asking to give him the production data dump to the following path \\138.90.17.56\OMNISAFE.
I really don't understand his requirement and he also wants me to zip the export backup file. How do I do that, Do you know any unix command to zip backup files.
thanks and regards
cherry

Well Thanks for your reply.....my oracle version is 11.2.0.3.b and if we have the compression option can you please elaborate how to do that......
It's in the documentation. See Data Pump Export
let us say my expdp file is abc.dmp...should I give the command gzip abc.dmp or any different.
Let me google that for you
One more question what does teh customer mean by production data dump to the following path \\138.90.17.56\OMNISAFE. please explain
How do we know what the customer means? Why don't you ask him?
That said, it looks like a url to an ip address and a defined folder at that ip address. Again, if the customer wants you to send them a file, you need to be working with said customer on the mechanics of accessing their system.
All that said ....
Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- *Read a chapter a day from the Concepts Manual*.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- *When you have finished reading the Concepts Manual, do it again*.
Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime.

Export backup failing with ORA-1555snapshot too old: rollback segment ERROR

DB version =8.1.7.4
OS=Solaris =5.10.
I know this is outdated. But still we are supporting this version of database.
We are facing ORA-1555 error daily when we are running the export backup of database. Consistent parameter is set to N .
I needed to know why export uses rollback segments during export operation. even though CONSISTENT parameter is N.
Thanks,
Edited by: ahshivap on Dec 12, 2012 5:19 AM

Hi,
Consistent=y just mean the tables are consistent with each other. Oracle still has to guarantee that each individual table is at least consistent with itself. That's your issue.

Hello. Thanks for the inputs on CONSISTENT option. There are pre-laid change mgmt processes in every organisation which needs to be maintained/taken in account before such changes are made, and that too, with client approvals, etc. Since it was not a feasible option to get EXPDP or RMAN implemented at this point, so was this question raised.
There is a small issue, however, if we use CONSISTENT=N. Below is an extract from asktom.oracle.com:
>
imagine if you started an export at 9am of the EMP and DEPT tables.
EMP started exporting at 9am and DEPT at 9:15am.
Now, the EMP data would be "as of 9am", but the DEPT data would be as of 9:15am. What if
you import that data now -- will it work? maybe, maybe not -- perhaps at 9:10am, someone
fired the last employee in department 50 and deleted department 50. Your EMP export
would have them in this deptno, your DEPT export would not have this deptno. The import
would fail.
If you use consistent=y, Oracle will export all of the data "as of 9am", so deptno=50
will be included in all tables and the import will succeed.
>
That's one of the risks involved.
Is there any other solution we can have in place for this issue? Thanks.

It is really, Really, REALLY difficult to fix a problem that can not be seen.
use COPY & PASTE so we can see what you do & how Oracle responds.

We have go-live for half a year, there are around 500 requests in PRD, all these transaction data need to be export / backup before re-installation.
Could any one give us any advice?
Thanks a lot!

Hi,
This will be handled by BASIS team, you need not worry. Once the data was restored you need to amke sure all the production data was avilable with configuration settings, audit trial, all the requests data.
If this was first time you are performing, better check out restore on non-production server and identify any issues and resolve and then proceed onto production.
Backup and restore will be done only by basis and documents avilable in market place, also that was dependent on your DB type.
regards.

Export backup degrades performance?

Hi all,
Please suggest me if i take export backup of the database does it degrades performance of the database when the applications are connected?
Can this export be done while application is using the database?
Is there any risk concerning performance of the application during DB export?
Thank you.

An export is a query against the database. Generally, a query to extract the whole schema or whole table (or whole database). It has the same performance impact as any query doing FullTableScans against the tables being exported.
Note :If you do an export using 'exp', ensure that you use "CONSISTENT=Y" or "FLASHBACK_SCN" or "FLASBACK_TIME" to get consistency across tables, else exp does Table-level consistency.
With 'expdp' you can use FLASHBACK_SCN or FLASHBACK_TIME

Use ctxload with -thesdump to export and -thes to import as in the examples from the online documentation below.

14.1.3.1 Thesaurus Import Example
The following example imports a thesaurus named tech_doc from an import file named tech_thesaurus.txt:
ctxload -user jsmith/123abc -thes -name tech_doc -file tech_thesaurus.txt
14.1.3.2 Thesaurus Export Example
The following example dumps the contents of a thesaurus named tech_doc into a file named tech_thesaurus.out:

Export Backup takes 90% CPU Usage

hi Gurus,
We have export backup scheduled on PROD database. We have noticed that export backup consumes alot of CPU usage.
Database: Release 9.2.0.6
CPU usage: Around 90% TO 95% during backup activity
Backup last for around 20min
Script file_
@echo off
for /F "tokens=2-4 delims=/ " %%f in ('date /t') do (
set mm=%%f
set dd=%%g
set yyyy=%%h
set DT=%mm%%dd%%yyyy%
set ORACLE_SID=PRODUCT1
echo Oracle SID set to PRODUCT1
exp SYSTEM/DIAL1NG file=E:\ExportBackup\PRODUCT1\PRODUCT1_EXP_FULL_%mm%%dd%%yyyy%.dmp log=E:\ExportBackup\PRODUCT1\PRODUCT1_EXP_FULL_%mm%%dd%%yyyy%.log full=y grants=y indexes=y statistics=none direct=y consistent=y buffer=5000000
goto END
: END
please advise us whether this can be fine tuned?
