I am running Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bit Production on RHEL5. I am busy with data pump import, from the log I can see that my import is busy with the constraints.
I am using parameter EXCLUDE=INDEX during the import and I created the index DDL's.
Now I want to manually create indexes while the import is busy.
Will this be advisable to do or what would be the impact?
I have a quiet large table (around 140 GB) and i want to create an index on it. I was wondering, before i fire my my create index statement, i know in advance how long will it take to complete? I know after the create index is executed, we can monitor and gets some estimates from longops view. but is there any way we estimate before hand?
Also my database is in archive log mode and what would be the fastest way to create an online index?
is there any way to reduce the index creation time.
in my case one index creation took 5 minute and there are 5 indexes , so it took 25 minutes.
Facts:
Oracle 10.1.0.5
AIX 5.3
My table, HMTX have 10 partitions each of one have 6 millions of rows (average). We have 7 partitioned LOCAL indexes in that table.
Every month we load data into a new partition (6 million of rows aprox) and drop the oldest partition in table HMTX.
In order to do that we have a script that contain the next statements:
drop of all indexes
drop index n1;
drop index n...;
drop index n7;
[Code]...
create indexes again with tha same storage and degree parameters
CREATE INDEX hmtx_TST_N1 ON hmtx (campo1, campo2, campo3 .... campo8)
TABLESPACE xxxx
PCTFREE 0
INITRANS 2
[Code]....
My problem is in rhe index creation section, despite use parallel with degree 8 and nologging the index was created in :
Elapsed: 02:43:50.85.
In past months that index was created in :
Elapsed: 01:43:36.94
Elapsed: 04:48:31.24
Elapsed: 00:57:16.28
there are another way in order speed the index creation ?? o another way to disable ths index ??
I have a table which if approc 5GB in size.I am trying to create a partition table from it. I created the new table,but when i am creating local indexes, i am getting an error when i create a unique key. I ll post the creation scripts:
CREATE TABLE A_PT_ORDREG
(
BUS_UNIT VARCHAR2(5) NOT NULL,
ORDER_NO VARCHAR2(15) NOT NULL,
PT_CODE VARCHAR2(15) NOT NULL,
REG_NO VARCHAR2(15) NOT NULL,
AS_APPLICATION VARCHAR2(5) NOT NULL,
[code].....
THE INDEX:
CREATE UNIQUE INDEX PK_A_PT_ORDREG ON A_PT_ORDREG (BUS_UNIT, ORDER_NO, SEQ_NO) local;
I am getting the following error:
ORA-14039: partitioning columns must form a subset of key columns of a UNIQUE index
We have a table called address and having the address fields and city ,state etc. The table will store huge amount of data .We need to query on the table. I would like to know how can we fasten the query and improve the performance of the query by creating index on these columns...Query is given below . note that the nullable columns can have data
SELECT *
FROM address
WHERE address1 = 'a'

Is there any way to reduce the index creation time. I have one table which has 7700000 records and every day this table get truncate and we create with create table as select statement and then create the 4 indexes and each index took 5 minutes so in totality it took 20 minutes in index creation.

On doing a explain plan on long running queries. i realized a couple of columns (that were used in the WHERE condition, were not having any indexes.)
More importantly, here we do not have a Test environment.
I would like to know if i can go ahead and create indexes for those 2 columns by issuing
CREATE INDEX index_name on table_name(Column_name);
on our PDB.
Would this be of any impact on our PDB? Do i check anything more prior to building these indexes. or Do have i create them at a down time of PDB.
I have database A (Working in Live environment) and Database B copy of Database (Not live) I have Restored whole database (A) RMAN backup file on Database (B) Previous week now i don't want to change anything in any schema and want to import only updated and new records in the table in Database B
There are around 20 schema If for example i have everything in new database B all required database objects like Procedure,functions, packages with indexes in all tables and data in tables, i just want to add new data and updated data.
IF i do following in source database
expdp directory=dpump_dir dumpfile=table_data.dmp content=data_only schemas=ACCMAIN,HRMAIN,..... include=TABLE
AND Import in destination database B, will it add new data and update existing one in table and not touch the table structure and indexes.
I am considering all of the capabilities and benefits of using Data Pump for exporting and importing extremely large data files. Would like to know if importing to tape is possible? If so, would the data be accessible if needed later?

My operating system is Windows Xp Professional and the Oracle database version is 10.2.0.
My task is to export datas using export utility. Following are the steps I did in my sqlplus connecting to a database db2.
SQL> CONN / AS SYSDBA
Connected.
SQL> ALTER USER scott IDENTIFIED BY tiger ACCOUNT UNLOCK;
User altered.
SQL> CREATE OR REPLACE DIRECTORY test_dir AS '/u01/app/oracle/oradata/';
Directory created.
SQL> GRANT READ, WRITE ON DIRECTORY test_dir TO scott;
Grant succeeded.
SQL> expdp scott/tiger@db2 tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log
I was not able to export the tables, resulting in the following error.

How (or having a script) to get, in PL/SQL, the parameters that have been given on a Data Pump command (export or import): mode (easy), tables/schemas list, exclude/include values and so on?
10.2 (preferred) or 11.2 as you want.
By default the Oracle utility expdp will not guarantee data consistency for particular point in time when the dump was taken.
When importing such dump you can get errors like
CODEORA-39083: Object type REF_CONSTRAINT failed to create with error...
ORA-02298: cannot validate (...) - parent keys not found
To make your Oracle data pump dumps consistent use flashback_scn or flashback_time option.
Example:
CODEexpdp myschema/... DIRECTORY=expdp_dir DUMPFILE=mydb_20110308.dmp logfile=mydb_20110308.log SCHEMAS=myschema FLASHBACK_TIME=\"TO_TIMESTAMP\(TO_CHAR\(SYSDATE,\'YYYY-MM-DD HH24:MI:SS\'\),\'YYYY-MM-DD HH24:MI:SS\'\)\"
I met some problems with data pump tools. We have a large db(oracle 10.2.0.5, single instance on hpux v11.11, data about 8TB), while we wanna migrate to Linux ia 64bit, 10.2.0.5 RAC. The migrate window is around 20 hours, so the window can NOT be assign more hours.
As we consider if impdp & expdp work can start together, that will be save a lot of time. So I wonder if there are any ways to implement this or any other ways can speed up and make the data integrate better?
why datapump is faster than normal exp ? one ans that i know is dp use block mode and exp use byte mode . is there any other major reason? if say i have database of size 10g and want to take datapump backup, but condition is that i can take dumpfile of size 2g only. there is any way to take full backup of database in part wise .

I created a new directory called IMPDMP with the directory path (using UNC pathing) to \serversharefoldersubfolder (our network mapped P drive, yes I included the backslash, but I have tried without it also).

My questions are this:
1) In interactive mode, does a dummy file expdat.dmp have to exist in the DATA_PUMP_DIR directory?
2) does my export have to reside in the DATA_PUMP_DIR directory (again, no disk space to handle the DMP file), one of the hard drives is just big enough to handle the space but since it has datafiles there also, it would crash during import when trying to extend.
I have an 11g data pump supplied by another party.I am on Windows 7(x64).I have experience using other databases, but not Oracle. The complexity of it all is a bit overwhelming...
I downloaded and installed [URL].I used the Database Configuration Assistant to create a database:
Template: Data Warehouse
Name/SID: database0
Password: password0
I then used the 'database0' Enterprise Manager:
Logged in as SYSTEM/password0 (Normal)
Import from Export Files
Entire Files
Host Credentials: myself (am Windows administrator)
All the rest defaults
The job appears to finish successfully.When I look at the schema (using razorsql), most tables seem to be there. However,a significant number are not. When I open data pump in a text editor, those missing tables are clearly there - definitions and data.When I look in the import.log, there are errors of the type:
error in creating database file '/db02/oradata/database0/stuff.dbf'
file create error, unable to create file
unable to open file
(OS 3) The system cannot find the path specified.
Failing sql is:
CREATE TABLESPACE "STUFF" DATAFILE '/db01/oradata/database0/stuff.dbf'
-- followed by the associated table creation errors.
So, does this mean that unix paths are hardcoded into the data pump, and is therefore incompatible with import into a Windows based system? Or are the paths symbolic, internal representations used by Oracle, and these errors are a symptom of an earlier, undisclosed problem?
The thing is, when I view the schema, the tablespace "STUFF" exists, just none of its tables.

when i'm trying to run an expdp command, i get this:
'expdp' is not recognized as an internal or external command
Now, i understand this is because i don't have the Bin directory of a client installation in my Path of the OS. My question is, which one exactly i need for using data-pump utility, and where to download it?
I've found lots of posts of people that had issues with defining the ORA_HOME$in in the $PATH, or having a client incompatibility issue throughout the web, but no answer to my specific question.

We should migrate our 10gR2 single-instance database with conventional file system to a two-node 11gR2 RAC on ASM (on same Windows Server platform…).
How can I migrate my production database using data pump? I have full data pump export from target but I don’t know how to import, whether the scheme after scheme, full import, do I need to first create manually tablespaces on destination, whether to exclude the index, constraint, statistics?
While using impdp I had set parallel to 16. Currently parallelism is 16 but there are only two workers with worker parallism 1.
1st worker is executing and 2nd worker is waiting.
Is my impdp running parallely? What does work parallelism mean?
