Duplicate huge schema

Hi all,
I have a schema that contains 2000 GB of data.
What is the best practice to duplicate the schema?
Thanks
dyahav

Hi all,
Thanks for the quick responses and great links.
I have to copy one schema of 2000 GB in the same machine and I can do it over a night (which means that it can be issued offline)
Actually, I have no experience in such schema size and I have to estimate the time required to do that and to find the best technique.
1. Do you know how to estimate the time required?
2. Is there any other technique to copy a schema?
3. If I have to copy the schema to other machine (identical HW and SW), is there other technique?
Thanks!

Duplicate a schema in XE

A co-worker is looking to duplicate our schema in XE. By duplicate, i mean a copy of the TABLEs, CONSTRAINTs, INDEXes, VIEWs, and SEQUENCEs, but not the data. This should only need to be done once.
From:Oracle9i Enterprise Edition Release 9.2.0.8.0
To: Oracle Database 10g Express Edition Release 10.2.0.1.0

How do i go about copying the schema?

Hi,
>>The command i used was (from Windows): exp user/pass@tnsname TABLES=(user.tablename) ROWS=N LOG=c:\a\log.txt FILE=c:\a\exp.txt
Keep in mind that you are using the TABLE clause. In this case, only tables will be exported. So, views, functions, sequences ... won't be exportted. Therefore, I advise you to perform the export below:
exp user/password file=user.dmp rows=n
>>EXP-00009: no privilege to export <owner>'s table <table>
What user are you using to take the export?

Splitting huge Schema/E-R Model into Modular Schema/Multiple E-R Models

Hi,
Currently we have huge DB Schema (1500+ Tables) using 1 single OWNER ID.
Based on Domain Partitioning,we intend to create 6 new OWNER IDs (based on individual Module/Domain)
and re-assign the appropriate Tables into the respective Domain.
basically we expect 1500 Tables under one OWNER ID would now be split
into 250 Tables per OWNER ID with a total of 6 new OWNER IDs being created.
We also will need to create 6 new E-R Models ,1 per OWNER ID
Trying to find out what could be the best possible way to do the "splitting" of a
linear huge Data Model, into 6 modular E-R models. Going forward, we would like
to maintain individual Models on per Domain basis rather than the existing monolithic Model.
Any suggestions or tips on achieving this using SQL Developer Data Modeler would be greatly appreciated.
What is the best and clean way of achieving this
Thanks
Auro

Hi Auro,
first you should be aware that you can have foreign keys created only between tables in one model.
If this is not restriction for you then you can proceed:
1) create one subview per future model and put in each subview tables that will constitute the model
2) each model in separate design
- use "Export>To Data modeler Design" - select subview that you want to export and only objects belonging to that subview will be exported

Moving Schema

Hi,
We have a requirement to move a huge schema from one database to another using RMAN. (similar to export and import)
Can someone please provide the steps/scripts or link where i can get this details.
Thanks!

Thanks!RMAN wont handle backup or restore of logical objects.
Use expdp/impdp to move schema.
Using RMAN you can restore/duplicate of entire database.

Schema Export using DBMS_DATAPUMP is extremely slow

Hi,
I created a procedure that duplicates a schema within a given database by first exporting the schema to a dump file using DBMS_DATAPUMP and then imports the same file (can't use network link because it fails most of the time).
My problem is that a regular schema datapump export takes about 1.5 minutes whereas the export using dbms_datapump takes about 10 times longer - something in the range of 14 minutes.
here is the code of the procedure that duplicates the schema:

Images (w/correct meta data) are in catalog and on disk, but LR 5.7 considers them new on Import

For reasons explained below, I want to try to re-import all my images into LR and hope that none/few are in fact considered new and are imported. Yet, for some folders, LR is apparently unable to detect that my source images are already in the catalog, and are on disk, and that the source file meta data matches what LR knows about the images. When I click an image in LR and Show in Finder, I do see the imported image on disk. I can edit the image in the Develop module. So, it seems good, but all is not well.   Sorry for the long post here, but I wanted to provide as much info as I could, as I am really seeking your help, which I'd very much appreciate.
Here are some screen shots that illustrate the problem:
Finder contents of the original images
LR folder hierarchy
an image as seen in LR
Finder content of external LR copy of images
import showing 10 "new" photos
The original images ... (I'm not sure why the file date is April 2001 but the actual image date is January 2011; I may have just used the wrong date on the folder name?)
The LR folder hierarchy ...
An image as seen in LR ...
The external folder containing the images in the LR library
But on import of the original source folder, LR sees 10 "new" photos ...
I tried "Synchronize Folder ..." on this particular folder, and it simply hangs half-way through as seen in the screen shot below.   IS THIS AN LR BUG?   This is really odd, since "Synchronize Folder ..." on the top-level folder completes quickly.
I have a spreadsheet of of the EXIF data for the original files and those created by LR. (I extracted this info using the excellent and free pyExifToolGui graphical frontend for the command line tool ExifTool by Phil Harvey.)   Almost all of the Exif data is the same, but LR has added some additional info to the files after import, including (of course) keywords. However, I would not have expected the differences I found to enter into the duplicate detection scheme. (I didn't see a way to attach the spreadsheet to this posting as it's not an "image".)
I'm running LR 5.7 on a 27" iMac with Yosemite 10.10.2, having used LR since LR2. I have all my original images (.JPEGs and RAWs of various flavors) on my internal drive on the Mac.   To me this is like saving all my memory cards and never re-using them.   Fortunately, these files are backed up several ways.   I import these images (copying RAWs as DNG) into LR with a renaming scheme that includes the import number, original file creation date and original file name.   There should be one LR folder for each original source file folder, with the identical folder name (usually a place and date). I store the LR catalog and imported images on an external drive. Amazingly and unfortunately my external drive failed as did it's twin, same make/size drive that I used as a backup with Carbon Copy Cloner.   I used Data Rescue 4 to recover to a new disk what I thought was almost all of the files on the external drive.
So, I thought all would be well, but, when I tried "Synchronize Folder" using the top-level folder of my catalog, the dialog box appeared saying there were over 1000 "New" photos that had not been imported. This made be suspicious that I had failed to recover everything.   But actually things are much worse than I thought..   I have these counts of images:
80,0061 files in 217 folders for my original source files (some of these may be (temporary?) copies that I actually don't want to import into LR)
51,780 files in 187 folders on my external drive containing the LR photo library
49,254 images in the top-level folder in the LR catalog (why different from the external file count?)
35,332 images found during import of the top-level folder containing original images
22,560 images found as "new" by LR during import
1,074 "new" images reported by Synchronize Folder ... on the top-level folder in the catalog; different from import count
Clearly things are badly out of sync.   I'd like to be sure I have all my images in LR, but none duplicated.   Thus, I want to try to import the entire library and have LR tell me which photos are new. I have over 200 folders in LR. I am now proceeding to try importing each folder, one at a time, to try to reconcile the differences and import the truly missing images. This will be painful. And it may not be enough to fully resolve the above discrepancies.
Does anyone have any ideas or suggestions? I'd really appreciate your help!
Ken

Thanks for being on the case, dj!   As you'll see below, YOU WERE RIGHT!      But I am confused.
    1. Does the same problem exist if you try to import (not synchronize) from that folder? In other words, does import improperly think these are not duplic
YES. Import improperly thinks they are NOT duplicates, but they are in fact the same image (but apparently not the EXACT SAME bytes on disk!)
    2. According to the documentation, a photo is considered a duplicate "if it has the same, original filename; the same Exif capture date and time; and the same file size."
This is my understanding too.
    3. Can you manually confirm that, for an example photo, that by examining the photo in Lightroom and the photo you are trying to synchronize/import, that these three items are identical?
NO, I CAN'T! The ORIGINAL file name (in the source folder) is the SAME as it was when I first imported that folder. That name is used as part of the renaming process using a custom template. However, the file SIZES are different.    Here is the Finder Get Info for both files. Initially, they appeared to be the same SIZE, 253KB, looking at the summary. But, if you look at the exact byte count, however, the file sizes are DIFFERENT: 252,632 for the original file and 2252,883 for the already-imported file:
This difference alone is enough to indicate why LR does not consider the file a duplicate.
Furthermore, there IS one small difference in the EXIF data regarding dates ... the DateTimeOriginal:
                                                                                               CreateDate              DateTimeDigitized                    DateTimeOriginal              FileModifyDate                              ModifyDate
ORIGINAL name: P5110178.JPG                                     2001:05:11 15:27:18    2001:05:11 15:27:18-07:00        2001:01:17 11:29:00        2011:01:17 11:29:00-07:00       2005:04:24 14:41:05
After LR rename: KRJ_0002_010511_P5110178.JPG    2001:05:11 15:27:18    2001:05:11 15:27:18-07:00        2001:05:11 15:27:18        2011:01:17 11:29:02-07:00       2005:04:24 14:41:05
So ... now I see TWO reasons why LR doesn't consider these duplicates.   Though the file NAME is the same (as original), the file sizes ARE slightly different. The EXIF "DateTimeOriginal" is DIFFERENT.   Therefore, LR considers them NOT duplicates.
     4a. With regards to the screen captures of your images and operating system folder, I do not see that the filename is the same; I see the file names are different. Is that because you renamed the photos in Lightroom (either during import or afterwards)?
I renamed the file on import using a custom template ...
        4b. Can you show a screen capture of this image that shows the original file name in the Lightroom metadata panel (it appears when the dropdown is set to EXIF and IPTC)?
SO ....
The METADATA shown by LR does NOT include the ORIGINAL file name (but I think I have seen it displayed for other files?). The File SIZE in the LR metadata panel (246.96 KB) is different from what Finder reports (254 KB). There are three "date" fields in the LR metadata, and five that I've extracted from the EXIF data.   I'm not sure which EXIF date corresponds to the "Data Time" shown in the LR metadata.
I don't understand how these differences arose.   I did not touch the original file outside LR.   LR is the only program that touches the file it has copied to my external drive during import. (though it was RECOVERED from a failed disk by Data Rescue 4),
NOW ...
I understand WHY LR considers the files different (but not how they came to be so). The question now is WHAT DO I DO ABOUT IT?   Is there any tool I can use to adjust the original (or imported) file's SIZE and EXIF data to match the file LR has? Any way to override or change how LR does duplicate detection?
Thanks so very much, dj.   Any ideas on how to get LR to ignore these (minor) differences would be hugely helpful.

External tables in 9i

Hi,
Could anybody tell me if there is possible to export a huge table (900 mil records) to an external file and then create an external table based on this external file ?
Does anybody know the best way to export/ import a huge schema to save time and disk space ?
And all these in Oracle 9i.
Thanks,
Paul

Hi Paul,
export a huge table (900 mil records) to an external file and then create an external table based on this external file ?Yes! You can use the SQL*Plus "spool" command, and extract the data in a comma-delimited format (CSV). Then, you can define an external table to point to the flat file. I have some notes nere:

Hi Yatan
The error is mostly there may be some Duplicate variable/schema element decalared in the wsdl or the xsd referred in the wsdl. Like in WSDL for any Operations, most of the times, we use input and outputs as complex xsd element. We declare these xsd in the same file or in another file and import that in the .wsdl file. So check or validate your XSD file for any Duplicates.
In JDeveloper itself, I think, you can open XSD or WSDL and validate it from right click menu options like that.
Thanks

Error when creating web service client in netbeans

i tried to create a web service client from a wsdl and an error pops up:
web service client can not be created by jaxws:wsimport utility.
reason: com.sun.tools.xjc.api.schemacompiler.resetschema()v
There might be a problem during java artifacts creation: for example a name conflict in generated classes.
To detect the problem see also the error messages in output window.
You may be able to fix the problem in WSDL Customization dialog
(Edit Web Service Attributes action)
or by manual editing of the local wsdl or schema files, using the JAXB customization
(local wsdl and schema files are located in xml-resources directory).
end of error message
I am using netbeans 6.0 RC 2 and the bundled tomcat 6.0.13. Please help me.

Import Process Slow .. Suggestions for Speedup ?

Hi,
I am doing an import of data from a dump file since the last 15 hours. The size of the database is 15GB on a 10.2.0.3.
The majority of the size is in one particular schema.
The requirement is to duplicate the schema into a new tablespace. I created the structure off of the DDL from an index file and then loading data using :
imp system/password buffer=125000000 file=............. log=....._rows.log fromuser=scott touser=alice rows=y ignore=y constraints=n indexes=n
Some how since the last 12 or so hours it is trying to load data into a table consisting of 6 million rows, and still hasnt completed.
I can see for a fact that the UNDO TS has crossed 6GB and the tablespace for the schema around 3GB.
The redolog is 50MB each of 3 groups and there is constant Checkpoint incomplete as well.
Now this is a test machine, but the machine where this is supposed to happen tomorrow is a 9.2.0.3 on a Solaris box.
Is there any way to speed up this process .. maybe stop all the logging ? What are the other ways I can import all this data faster than the current unpredictably slow process.
Thanks.

If you are copying data within the same database, why not use CTAS or INSERT, with PARALLEL and APPEND ?
eg
ALTER SYSTEM SET PARALLEL_MAX_SERVERS=8;
CREATE TABLE newschema.table_a AS SELECT * FROM oldschema.table_a where 1=2;
ALTER TABLE newschema.table_a NOLOGGING;
ALTER TABLE newschema.table_a PARALLEL 2;
ALTER TABLE oldschema.table_b PARALLEL 2;
ALTER SESSION ENABLE PARALLEL DML;
INSERT /*+ APPEND */ INTO newschema.table_a SELECT * FROM oldschema.table_a ;
COMMIT;
ALTER TABLE oldschema.table_a NOPARALLEL;
CREATE INDEX newschema.table_a_ndx_1 ON newschema.table_a(col1,col2) PARALLEL 4 NOLOGGING;
ALTER TABLE newschema.table_a NOPARALLEL;
ALTER INDEX newschema.table_a_ndx_1 NOPARALLEL;and run multiple tables in parallel (table_a being in the above block of code, table_b being in another block of code running concurrently, those each block of code using 4 ParallelQuery operators.

Sequences on more shemas. How to use???

A big trouble using correctly sequences in oracle lite.
Since now i had only one olite publication linked to a schema on backend db, with many objects: tables, indexes, views and 5 sequences.
Example:
publication --> schema
schema.seq1, schema.seq2, ... , schema.seq5
reachable by olite client as:
db = $USER_PUBLICATION
Now i have to "duplicate" this schema and deploy another publication, adding a prefix.
Example:
new_publication -> new_schema
db = $USER_NEW_PUBLICATION
I found no problem for all objects but sequences,
because tables, index, etc had the right schema as "owner",
but i did not found any parameters like owner for sequences.
Explaining better,
i need to use the same sequence name: seq1, seq2, ..., seq5 for both publications,
referring to the right sequences on the right schema, but i'm not sure if (and how) this is possible.
Could you help me?
Thanks.

we had a similar issue when we changed our application from 'standard' oracle lite (complete and fast refresh PIs) to use queue based PIs.
We did a workaound for the problem by
1) do not include the sequences at all in the second application (you get erors if you do)
2) run the following (fusionbci2 is our new application, fusionbci is the old, and fusionbci2 is effectively a clone of fusionbci)
-- fusionbci2_sequences.sql
-- associate all sequences with the fusionbci2 application
DECLARE
l_fusionbci2 VARCHAR2(30);
-- this cursor get the internal publication id for the fusionbci2 application
CURSOR c_fusionbci2 IS
SELECT name
FROM cv$all_publications
WHERE name_template LIKE 'fusionbci2%';
BEGIN
OPEN c_fusionbci2;
FETCH c_fusionbci2 INTO l_fusionbci2;
CLOSE c_fusionbci2;
-- this insert creates copies of the sequence relationship entries for the fusionbci application
-- linked to fusionbci2
INSERT INTO c$pub_objects
(pub_name
,db_name
,obj_id
,obj_type
,obj_weight)
SELECT l_fusionbci2
,'fusionbci2'
,obj_id
,obj_type
,obj_weight
FROM c$pub_objects
WHERE db_name='fusionbci'
AND obj_type='NA_SEQ';
END;
NOTE this works, but is probably not recommended by oracle, and should only be used where individual clients will only use one of the applications at a time (if they use both the sequence ranges are likely to overlap)

The progress of gather_schema_stats

hello,
database version oracle 10.2.4.0 hpux
we use following options of      gather_schema_stats to gather statistics for a huge schema:
DBMS_STATS.gather_schema_stats ( ownname => '<SCHEMA>', -
     estimate_percent =>DBMS_STATS.AUTO_SAMPLE_SIZE, -
     cascade => true, -
     granularity => 'ALL' );
how can i determine the progress of gather_schema_stats ? does a internal table exists to monitor this ?
we want / must now the status of progress ?
regards,

You can query the V$SESSION_LONGOPS table. Something like
SELECT *
FROM v$session_longops
WHERE time_remaining > 0will show you all the sessions that have long-running operations. GATHER_SCHEMA_STATS will populate this view, as will other Oracle operations that take more than a few seconds (i.e. a full scan of a large table).

Impdp ORA-31684: Object type USER:"USERNAME" already exists

Hi,
I use expdp/impdp to duplicate one schema in a database like this:
expdp system/manager@DB SCHEMAS=SCHEMANAME
then I drop destination Schema like this
drop user SCHEMANAME_NEW cascade;
create user SCHEMANAME_NEW identified by PW default tablespace TABLESPACENAME;
and impdp like this
impdp system/manager@DB FULL=Y REMAP_SCHEMA=SCHEMANAME:SCHEMANAME_NEW
and I get this error:
Processing object type SCHEMA_EXPORT/USER
ORA-31684: Object type USER:"SCHEMANAME_NEW" already exists
I know that the import was successful, but this error breaks my hudson build.
I tried to add exclude like this
impdp system/manager@DB FULL=Y REMAP_SCHEMA=SCHEMANAME:SCHEMANAME_NEW exclude=USER:\"=\'SCHEMANAME_NEW\'\"
I need to get rid of this error.
Thx

You get this error because you precreated the user. All you need to do is add
exclude=user
to either your expdp or impdp command. Or let impdp create the user for you. If you need it to have a different tablespace you can just use the
remap_tablespace=old_tbs:new_tbs
This should take care of the default tablespace on the create user command.
