I have a problem with DBMS_DATAPUMP.metadata_filter.Let's suppose that I need to export a huge list of tables (a,b,c,d,e,f,g,h,i...). Let's suppose that the list is dynamic do NOT want to use
DBMS_DATAPUMP.metadata_filter (handle => h1,
NAME => 'NAME_EXPR',
VALUE => 'IN (''a'', ''b'', ...)',
object_type => NULL);
In my_export_table there is the list:
CREATE TABLE my_export_table
(
EXPORT_OBJECT_NAME VARCHAR2(50 BYTE)
)
Now I'm trying to use this form:
DBMS_DATAPUMP.metadata_filter (handle => h1,
NAME => 'NAME_EXPR',
VALUE => 'IN (SELECT a.export_object_name FROM my_export_table a, user_objects b WHERE a.export_object_name = b.object_name AND b.object_type = ''TABLE'')',
object_type => NULL
);
but it results in error.
Processing object type SCHEMA_EXPORT/TABLE/TABLE_DATA
ORA-39125: Worker unexpected fatal error in KUPW$WORKER.GET_TABLE_DATA_OBJECTS while calling DBMS_METADATA.FETCH_XML_CLOB []
ORA-00942: table or view does not exist

As a part of our back up we used to export the production data every day using Original export Utility but from 11g original export Utility is de supported and also datapump doesn't support XML Objects so is there any other way to export the full database else any option to export xml Object using datapump.

We are firing a normal Drop command on our database and the database version is 10.2.0.4.The database is running on AIX v5.The command is taking more time than usual .
When i am monitoring the session i can see that a call is being made to procedure "aw_drop_proc".Could i ask you if this is something that is taking more time than usual.
We are not having any partitions on the nested tables .We have a pack of tables and we are dropping this pack through a procedure.The pack comprises of nested tables & normal tables.To drop a nested table it is taking around 6 seconds(Table with no rows) and a normal table(With no rows) it is taking 17 milli seconds.We have a partition on Normal table.
The same operation in windows is taking very less time when compared to AIX.

I have upgraded oracle database from 9i to 11g using export and import utility. After migration we are facing performance issue in report generation, We have observed that First execution of report is taking very long time and when we generate the same report 2 -3 times there is considerable change in the execution time and it is more better than the first execution.
2 days back I have restarted the database and found the same issue. There are around 300 Reports and it is not possible to generate all the reports 2-3 times every time we restart the database.

I'm taking export dump using expdp of some schema's of total size is 300GB. This is the par file:
DIRECTORY=expdp
FILESIZE=32212254720
DUMPFILE=expdp_schema01.dmp,expdp_schema02.dmp,expdp_schema03.dmp,expdp_schema04.dmp,expdp_schema05.dmp,expdp_schema06.dmp,expdp_sche ma07.dmp,expdp_schema08.dmp,expdp_schema09.dmp,expdp_schema10.dmp,expdp_schema11.dmp,expdp_schema12.dmp,expdp_schema13.d
[code]....
here one biggest schema size is 250GB and the total size of all the schema's is 300GB. The file where am taking the dump has 350GB space but even then the expdp failed saying
ORA-39095: Dump file space has been exhausted: Unable to allocate 8192 bytes
why it failed and how to restart it and make sure it runs successfully without error.

We have three instances on the RAC, When I create a directory is there a default instance that it gets created on? When I execute an datapump export on instance 1, it works but on 2 and 3 it fails with error relating to directory.
Error -
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 475

Is my only option is to use shared storage space?

Currently we are using "exp and imp" utilities to unload from production and load into Dev server. While importing, we are following below steps
(1) Load only data [by specifying INDEXES=N in the par file]
(2) Unlock statistics
(3) Load indexes, other objects [by specifying ROWS=N]
After doing these steps, both data, indexes and others objects are loaded. To verify indexes, we are checking DBA_INDEXES.
DBA_INDEXES :
-------------
OWNER INDEX_NAME TABLE_NAME STATUS LAST_ANALYZED
----- ---------- ---------- ------ -------------
MYSCH CP_INDEX_1 CP_TABLE_1 VALID 14/JAN/12
Question :-
(1) Does imp utility rebuild the indexes while loading data ? or it simply takes the rows from dump and load into test system without building from scratch ?
(2) I am trying to replace 'exp' and 'imp' with datapump utilities ? But, I am confused about the parameters to be used ?
(a) Can I load both data and meta data at the same time (Using CONTENT=ALL option) ?
(b) I am planning to implement this in two steps :
first load only metadata using - CONTENT=METADATA_ONLY TABLE_EXISTS_ACTION=REPLACE
then, load data - CONTENT=DATA_ONLY.

I have a Datapump Export File which was created in Schema mode.
I have to import the tabelles in a new database where a have to use the REMAP SCHEMA Parameter.
Additionally I would like to add a prefix to tablenames.
For example:
original tablename: THE_TABLE
Name after import: IMP_THE_TABLE
Is there a way to add a prefix while using Datapump Import?

I'm trying to deploy the schema using DATAPUMP API. The user from which the schema get deployed has the direct privilege of CREATE USER (not through role). But got the insufficient privileges error.
Processing object type SCHEMA_EXPORT/USER
ORA-31685: Object type USER:"SCOTT1" failed due to insufficient privileges. Failing sql is:
CREATE USER "SCOTT1" IDENTIFIED BY VALUES '4EBB0DDE3C79FE47' DEFAULT TABLESPACE "USERS"

But the user get created successfully when run the CREATE statement manually.I have created the user manually and again run the deployment procedure. Got the below error for ROLE_GRANTS.
Processing object type SCHEMA_EXPORT/ROLE_GRANT
ORA-39083: Object type ROLE_GRANT failed to create with error:
ORA-01932: ADMIN option not granted for role 'EXP_FULL_DATABASE'
Failing sql is:

The user has EXP_FULL_DATABASE with ADMIN Option and IMP_FULL_DATABASE with ADMIN option direct privileges.which privileges the user needs to deploy the schema successfully?

I am using Datapump import using database link to import an entire schema from another Server but it gives issues with constraints.I tried to first only import the metadata and then disable the constraints and import data and enable constraint but in this case the temp tablespace keeps filling up and i am out of space. Is there any method to do a full import including constraints and indexes.

by using below command:
expdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log
after that i zip that dump and move it to external usb and now i need that table i copy that table and unzip that that dump
Command i am using to do the import is :
impdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=impdpEMP_DEPT.log
But the query of import is still runing even not showing any amount of rows to be imported.
i already make the tablespace in which the table was previosuly before dropping but when i check the sapce of tablespace that is also not consuming one error i got preiviously while performing this task is:

How can we tune our RMAN Duplicate as it was taking 10+ hours to finish. Current production database size is 800GB. Approx duration of rman online backup (FULL, including archived logs) is 4 to 5 hours.
Here's the rman backup script we used:
sql 'alter system archive log current';
list archivelog all;
run
{
show all;
report schema;
backup database plus archivelog delete all input;
}
exit
Here's the rman duplicate command we used:
run
{
set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 02:30:00', 'Mon DD YYYY HH24:MI:SS')";
allocate auxiliary channel ch1 type disk;
duplicate target database to testdb;
}

We have data archive scripts, these scripts move data for a date range to a different table. so the script has two parts first copy data from original table to archive table; and second delete copied rows from the original table. The first part is executing very fast but the deletion is taking too long i.e. around 2-3 hours. The customer analysed the delete query and are saying the script is not using index and is going into full table scan. but the predicate itself is the primary key,More info below
CREATE TABLE "APP"."MON_TXNS" ( "ID_TXN" NUMBER(12,0) NOT NULL ENABLE, "BOL_IS_CANCELLED" VARCHAR2(1 BYTE) DEFAULT 'N' NOT NULL ENABLE, "ID_PAYER" NUMBER(12,0), "ID_PAYER_PI" NUMBER(12,0), "ID_PAYEE" NUMBER(12,0), "ID_PAYEE_PI" NUMBER(12,0), "ID_CURRENCY" CHAR(3 BYTE) NOT NULL ENABLE, "STR_TEXT" VARCHAR2(60 CHAR), "DAT_MERCHANT_TIMESTAMP" DATE, "STR_MERCHANT_ORDER_ID" VARCHAR2(30 BYTE), "DAT_EXPIRATION" DATE, "DAT_CREATION" DATE, "STR_USER_CREATION" VARCHAR2(30 CHAR), "DAT_LAST_UPDATE"
[Code]...
Data is first moved to table in schema3.OTW. and then we are deleting all the rows in otw from original table. below is the explain plan for delete

datapump on Windows 2003/R11.2 I have a batch file that creates a daily dump of a schema in the DATA_PUMP_DIR - However, it doesn't! The script is as follows: REM Script to perform data pump export of the user01 schema and move to the
desktop.SET CURRDATE=%DATE:~10,4%%DATE:~4,2%%DATE:~7,2%SET CURRTIME=%TIME:~0,2%%TIME:~3,2%%time:~6,2%SET CURRTIME=%CURRTIME: =0%SET DATESTAMP=%CURRDATE%_%CURRTIME%SET DUMP_FILE=user01_EXP_%DATESTAMP%.DMPSETLOG_FILE=user01_EXP_%DATESTAMP%.LOGexpdp "sys/pwd@db as sysdba" directory=DATA_PUMP_DIR dumpfile=%DUMP_FILE% schemas=user01 logfile=%LOG_FILE% MOVE

For some reason when this is run from a remote server as a batch it fails to create a file although the output from the scripts has no errors apart from move statements and the expdp output is all good (it states that the file was created in the expected location).If the expdp command is run on the server itself it is all good.

the database (11gR2) is located on Linux server. A business application is installed on a Windows server with an Oracle client 11g.The application is able to start a datapump export, but as matter of fact the dumpfiles are always written to the Linux-server. The directoryobject is defined as DATA_PUMP_DIR (which is the default directory).
Now we are supposed to change the datapump export in a matterthat the dumpfiles get written to the Windows server. Creating a new directory (e.g. c:datapump) and starting than the datapump from theclient always raises the errors
ORA-39002: ...ORA-39070: ...ORA-29283: ...ORA-06512: in "SYS.UTL_FILE", Zeile 536ORA-29283: ...
Is it possible at all to start a datapump export from a Windows client and writing the dumpfiles to the Windows server itself? Or do the dumpfiles always written to the database-server?
