'fromuser' to 'touser' option in datapump

Dear Friends ,
I m using oracle 10g in AIX platform . I take a full export (expdp)using datapump . Now I want to import it in another database in my test server . In test database I just import two user (Like user1,user2 ) from the export dump , i.e., I just want to use 'fromuser' , 'touser' option .
How can I do it in datapump ?
plz help ... ..

The EXCLUDE options to filter expdp or impdp to filter specfic objects being exported or imported.
If you're exporting a TABLE and you dont want export indexes,triggers,statistics,you can use
Tables=A
EXCLUDE=INDEX,TRIGGER,STATISTICS.
it works the same way for Schema. If you're exporting a full database export and if you EXCLUDE=SCHEMA:"='SCOTT'", The SChema SCOTT will not be exported.
If I want to import 4 users (user1,user2,user3,user4) from a full 'import dump" >using 'impdp' , then how can I use "remap_schema" ?You haven't specified in which schema the data to be imported.
REMAP_SCHEMA=scott:newscott - load database objects from a source schema (SCOTT) to a target schema (NEWSCOTT).

FLASHBACK_SCN option within datapump

I am trying to use the datapump option FLASHBACK_SCN by setting a variable within a script as the value from "SELECT dbms_flashback.get_system_change_number FROM dual;" in the following way.
sqlplus '/ as sysdba' <<EOF
set head off
spool flashback_scn.output
SELECT dbms_flashback.get_system_change_number FROM dual;
spool off
exit;
EOF
sed '/^$/d' flashback_scn.output |\
sed -e "s/[ <tab>]*//g" > flashback_scn.list
export FLASHBACK_SCN=`cat flashback_scn.list`
The variable FLASHBACK_SCN is then passed to the option and the datapump export performed. This has worked fine on a test database but the SCN is a lot smaller number than in production. I am now trying to run this in production but the value that comes back from "SELECT dbms_flashback.get_system_change_number FROM dual;" is as follows.
GET_SYSTEM_CHANGE_NUMBER
9.2196E+12
And datapump does not see this as a valid SCN nor does a select statement using the option of "AS OF SCN", I just get the error "specified number is not a valid change number.
Can anyone suggest a way to get the value as a proper value and not a "to the power of what ever" value.
Kind regards.
Graeme.

Hi Graeme,
This is only a display think of sqlplus.
Try this:
sqlplus '/ as sysdba' <<EOF
set head off
col get_system_change_number format 9999999999999999999999
spool flashback_scn.output
SELECT dbms_flashback.get_system_change_number FROM dual;
spool off
exit;
EOFthe format change the display to optional digits (in this case 22 digits, you can set it to whatever you like).
By the way, I take the date and use FLASHBACK_TIME instead of FLASHBACK_SCN, but it really doesn't matter.

Compression options for datapump

Hi
We are using 10.2 version of the db.
Using datapump
I have rad docs for datapump and as far as compression goes, can only see COMPRESSION=METADATA_ONLY.
We need to export something like a 200gb schema and we have no space for it.
Is this the only option for compression? (yes, I have looked into other mount points)
Looks like there isnt any. "Stay tuned for a data compression solution in a future release ".
Brilliant.
Thanks.

Good point,and one I will look into.
In the end I eventually got the dump - with 99% space used! I then scp-ed it to another box and gzipped it from there.
I am going to look into setting those environment variables as this took me two hours yesterday and yesterday was a Saturday - know what I mean?

How export one table along with data from one location to other location

Hi All,
I'm new in export/import practice.
Can anyone plz tell the steps along with commands to do the following:
1. I want to export a table with data from one location(computer) to other(computer) that are in same network.
2.Also from one user to another user.

First of all read documentation
Oracle Export/Import : http://docs.oracle.com/cd/B19306_01/server.102/b14215/exp_imp.htm
Datapump Export/Import : http://docs.oracle.com/cd/B19306_01/server.102/b14215/dp_overview.htm
If you are using Datapump or Traditional Export/import you need to follow following steps
*1) Take User dump via EXPDP on Computer A .*
For EXP
exp username/password owner=Test file=D:\test.dmp log=D:\test.log
For EXPDP
expdp username/password schemas=TEST directory=TEST_DIR dumpfile=TEST.dmp logfile=TEST.log*2) Copy that to Computer B*
*3) Import dumpfile.*
For IMPDP Use remap_schema optionhttp://www.acehints.com/2012/05/data-pump-impdp-remapschema-parameter.html
For IMP use fromuser and touser option
one user to another user imp

Import all but synonyms

Hi.
I have made a dump of schema with exp and OWNER option. Now i want to import that into other schema using FROMUSER and TOUSER options. But what i don't want is synonyms to be imported.
How can i exclude them from the import?
Thanx in advance

There's about 80 of themIt's not too much, we have more than 32000 synonyms in our db... ;-)
You can script the deletion to not have to write by yourself each synonym name.

System refresh from non-cluster to a MSCS cluster system

I have a system (call GTA) running NW 7.0 SR2 with both ABAP and Java instance. It runs on WIndows 2003 64-bit and SQL Server 2005. Now we want to migrate to a new set of hardware with Microsoft cluster (MSCS). I have installed this new system (Call GTB), MSCS clustered with both ABAP and Java instance and running no problem.
Now I am at the last point of the migration -- which I need refresh database GTB from GTA to capture live data. In WAS 6.40 ABAP, I just need perform a database backup/restore and execute SAPINST tool and everything works. Now based on SAP's "System Copy Guide", I need run export on source system and then run import on target system. In source system, it seems straight to export since it's central system (ABAP+ Java). However, when I get to target system, and when I choose cluster, it listed all items I have to choose (ABAP, SCS, 1st node, 2nd node, DB, enqueue, etc). They are exactly the same as a new installation. My questions are:
1. Do I have to go through all these steps for just refresh a database? If I go through these installation, am I overwrite something in my GTQ from GTA unnecessnaryly?
2. Can I just perform a database backup/restore? But what kind steps I need do to make cluster work after database refresh since original databse (GTA) is not a cluster system?
I appreciate you can provide some advise and share some experiences.
Thanks,
Yujun Ran

Hi
I have used the FROMUSER and TOUSER option of the IMPORT cmd to perform a system copy like you have described.
Steps:
1) Export BW4 (EXPORT USER=SAPBW4 ... )
2) In MCOD database, delete/drop all objects belonging to SAPBW1. From memory, I think I found it easier to DROP USER SAPBW1 CASCADE and the recreate the SAPBW1 user.
3) Import BW4 export (IMPORT FROMUSER=SAPBW4 TOUSER=SAPBW1 ..)
I don't use MCOD anymore because it is such a pain to refresh the systems.

Grant details required for user and schema

Hi
I have Oracle version - 10.2.0.4.0
We have Schema A (Lot of objects exist) and User B (No objects exist - acts as application user to access objects in other schema).
I have listed below doubts.
1) I want to know the method to find the list of users have access to objects in Schema A and privileges granted for the objects in Schema A
2) I want to know the method to find the list of grants provided to the schema objects to the user B

user1368801 wrote:
Thanks ajallen.
It really helped me.
one more question. I think DBA_TAB_PRIVS gives details for tables only right.
What about other objects like procedures, views etc. Go back to the Reference Manual and re-read the description of DBA_TAB_PRIVS. Re-read the specific description of TABLE_NAME.

Actually I am exporting 3 schemas (A,B,C) from production and importing them to test environment (A1, B1,C1) using fromuser and touser option.
Now I have to properly remap all the privileges, grants, synonyms etc.
There are so many objects and I am wondering how to remap properly.
It may be simple, as a newbie, your direction will be more helpful

Stats question

Hi All
This is related to schema stats from production to QA.
We have two DB
Production: ABC
QA: XYZ
Now,
I did export for schema ABC from production and inported the complete schema using 'fromuser and touser' option for exp into XYZ.
Then i created table for production (ABC) stats using :
exec dbms_stats.create_stat_table(ownname => 'ABC', stattab => 'ABCSTATS', tblspace => 'ABC_DATA');
Then, i gathered the stats:
exec dbms_stats.export_schema_stats(ownname => 'ABC',statown=>'ABC', stattab=>'ABCSTATS');
then, exported the table 'ABCSTATS' to file exp.dmp and imported into QA database XYZ.
PROD: exp file=/exp.dmp tables=ABCSTATS
QA: imp file=exp.dmp fromuser=ABC touser=XYZ
Now, i have complete data from PRODUCTION in QA and stats for production too in table ABCSTATS.
Now, When i do
exec dbms_stats.import_schema_stats(ownname => 'XYZ',statown=>'XYZ', stattab=>'ABCSTATS');
Then command runs sucessfully. But stats are not loaded as of procution.
I have stats cost coming for one query as 40,000 in production whereas in QA it is coming as 7,000 only.
Now the question is, is there something i am doing wrong? Or is this possible to load schema stats from one to another schema for same data structure.
OS: Sun10
DB: 10G 10.2.0.3.0
Thanks

Edited by: aps on Apr 13, 2009 9:31 AM

this possible to import diffrent schame stats into other? Can someone confirm?its possible. you have to perform few manual tasks.
create the stat table in source and export source schema stats.
export the stat table from source using exp utility.
transfer and import the stat table into target database.
Now, the Schema in Stat table isn't available in your target.So, you have to update the STAT table column C5 to target schema name.
Now, Import the stats using exec dbms_stats.import_table_stats.
Any special reason you want to do this? Instead, you can gather stats in current Target schema?

Export schema and import with different name

Hi ,
I need your assistance guys,
I need to export a schema from a database and then import it with different name to another database. How can I do that?
I export it with the following command:
exp userid=system/PW file=May_02_Export.dmp log=May_02_Export.log owner=schema_name statistics="none"
Now I want to import it but with different name (schma_name).

Why nothing work with me????????

Imp / from user/touser

what to clear my concepts
What fromuser-touser is doing, like in this example what is going on with
fromuser=(FA_F3PROD)
touser=(FA_R3TST01)
imp parfile=exp.parvi parfile
userid=system/*******@R3TST01
file=refresh.dmp
fromuser=(FA_F3PROD)
touser=(FA_R3TST01)
ignore=Y
commit=y
compile=y
buffer=2000000
resumable=y
resumable_timeout=12000
log=imp_refresh.log

In this case, Objects from schema FA_F3PROD user are being imported to FA_R3TST01 schema. So basically it is schema level import.

Datapump TTS from filesystem to ASM migration

Hi Experts,
I have to move the 1.5 TB of data which is on filesystem running on Solaris SPARC (single instance) to Linux x86 RAC (10.2.0.4) with ASM. I am considering the Transportable tablespaces option using datapump. But I have done the filesystem to filesystem datapump for TTS. Is there any way that I can use datapump TTS for filesystem to ASM directly ? Any suggestion and comments please.
Thanks
Shashi

I'm not sure what your question is. Data Pump works with ASM and supports transportable. You would have to copy your data files from your file system to your asm file system, then do the export on your source, copy the dumpfile to your asm target and then run data pump. If you have more specific questions, please list them.
Hope this helps.
Thanks
Dean

E-business database migration to linux (Cross platform) using datapump

You can use this option, just consider not using a high number to avoid ORA-31693 errors.

Oracle 11g imp erroneously tries to recreate existing tables with CLOBs?

I have a shell script for loading database dumps from both Datapump and the older exp/imp.
Often when loading dumps, I need to rename the schema owner and tablespace names (which is handled by REMAP_SCHEMA and REMAP_TABLESPACE in Datapump).
However I have a whole bunch of dumps created with exp at this point and not that many Datapump dumps yet. As such the old style dumps are handled by the shell script in this way:
1) A first pass imp is run using INDEXFILE to generate a file with the SQL to create tables and indexes. Options also include FROMUSER and TOUSER.
2) A series of sed command edit the SQL file to change the tablespace names (which are schema owner specific in our case).
3) The editted SQL file is run with sqlplus to create the tables and indexes.
4) A second pass imp is run to load the table rows as well as triggers, stored procedures, views, etc. Options include FROMUSER, TOUSER, COMMIT=Y, IGNORE=Y, BUFFER, STATISTICS=NONE, CONSTRAINTS=N
This shell script has been working great for loading exp dump files into Oracle 9 and Oracle 10 databases, but now that I'm trying to load these dumps into Oracle 11, it fails.
The problem is in step 4, the imp program is trying to create some of the tables that already were created with sqlplus in step 2. The problematic tables all seem to have CLOB columns in them. The table creation fails because it tries to use the tablespace names from the dump file, which do not exist in the destination database. And when the table creation fails, imp then decides not to load the rows for those table.
This seems like a bug in the Oracle 11 imp program. I don't understand why it thinks it needs to recreate tables that already exist when those tables have CLOB columns. Is there something different about CLOB columns in Oracle 11 that I should know about that might be confusing imp into thinking that it needs to create tables when they already exist? Maybe I need to do something to those tables in SQL so that imp does not think it needs to recreate them?
I know that the tables with the CLOBs were created correctly because I was trying to find some way to workaround this. For step 4, I tried using DATA_ONLY=Y, in which case imp does not try to create the tables and just loads the table rows. Of course using DATA_ONLY, I don't get a lot of other things like triggers, view and stored procedures. I started to try to get around that by doing 3 passes with imp, so that I could pick up the missing pieces by using an imp pass with ROWS=N, but strangely that has the same problem of trying to recreate the existing tables.

The only solution I've found so far as a workaround is rather convoluted.
1. I took an export using datapump's expdp of SCHEMA1 (in 10g it will skip the table with the xmltype).
2. I imported the data to my empty schema (SCHEMA2) using impdp. To avoid the error that the type already exists with another OID, I used the TRANSFORM=oid:n parameter e.g.
impdp user/pwd dumpfile=noxmltable.dmp logfile=importallbutxmltable.log remap_schema=SCHEMA1:SCHEMA2 TRANSFORM=oid:n directory=MYDUMPDIR
3. I then manually created my xmltype table in the SCHEMA2 and did a select into to load it (make sure you have the select privileges to do so):
INSERT INTO SCHEMA2.XMLTABLE2 SELECT * FROM SCHEMA1.XMLTABLE1;
4. I am still taking an export with exp of the xmltable as well even though I'm not sure I can do anything with it.
Thanks!
