• expdp, impdp Grid 11.2 and ACFS

  Version of the grid: 11.2.0.3
  OS: Red Hat Enterprise Linux 5.4
  
  A few months, our cluster of CARS, while taking a backup expdp in a local Linux file system, I got some errors. Remember the error code or the script now that I had too much work this day. The problem was solved when we used a location of file system ACFS as the directory for expdp object.
  
  Today, in the same cluster RAC, to reproduce that issue, I tested it with an expdp backup in a local Linux format
  file system (/ home/oracle/pumpDir) and the expdp finished without any problems.
  
  Someone at - it all met problems with expdp, impdp in environment RAC cluster in reason to use a local Linux file system?

  The error would be more probably "file not found".

  expdp/impdp (datapump) will begin in several parallel processes on the cluster. If all nodes cannot find the 'local' directory, you will get the above error.

  Bottom line, the parallel processes expdp may or may not be on a single node, so the 'directory' MUST be accessible across the cluster.

• expdp/impdp method in the database upgrade from 11.2.0.4 to 12.1.0.2 an error in logic of "command line"?

  Hi DBA:

  We are evaluating different methods of upgrading 11 GR 2 DB to 12 c (12.1.0.2) this year, it is very important for us to use the right method.  It was reported that when DB version was 9i and has been updated to 11g, there were some order of tables 'line' was wrong when execute SELECT statements in application (Java application) - at the moment I didn't if it is ' select * from... "or any specific part with a"where"clause, and what type of data was wrong (maybe sequence CLOB data, etc.).

  I think I know, ' exp/imp', "expdp/impdp" logical backup of DB methods.  Therefore, Oracle automatically import data and fix it in each table.  If no error in impdp connects after it's over, should not be any mistake, right?

  If the use of the method of 'creates a new data + expdp/impdp basis for schemas user' 11g 12 c port data, questions:

  1. this method will lead to erroneous sequence data when ordering?  If so, how to re - generate the sequence number?

  2. this method can bring CLOB, BLOB data and without any errors?  If error, how to detect and repair?

  I use the same method in the 10.2.0.5 to 11g port data, no problem.

  I'll keep this thread posted after getting more information from application.

  Thank you very much!

  INSERT... SELECT, CREATE TABLE in the SELECT and Export-Import will all "re-organize" the table by assigning new blocks.

  In place--update (using DBUA or command line) don't re-create the user tables (although it DOES not rebuild the data dictionary tables).  Therefore, does not change the physical location of lines for user tables.  However, there is no guarantee that a further reason for INSERT, DELETE, UPDATE instructions does not change the physical location of ranks.  Nor is it a guarantee that a SELECT statement will return always stored in the same order unless an ORDER BY is specified explicitly.

  If you export the data while it is still used, you don't avoid update sequences in the source database.  Usually results in a mismatching number sequence between the source database and the new database (imported). In fact, even the numbers may be different, unless you use CONSISTENT or FLASHBACK_SCN.  (These two options in exp / expdp do NOT prevent update sequences).   The right way to manage sequences is to rebuild or increase them in data imported with the values in the data source, once the import is complete.

• EXPDP/IMPDP run simultaneously

  There are the predictable problems running expdp and impdp simultaneously? I guess that 10g can handle, but maybe he can be a sort of blocking issues. Purely theoretical situation.

• Accelerate exp/imp or expdp/impdp

  Hello

  Is it possible to speed up and exp/imp or expdp/impdp that already works? Is is possible to speed up a run RMAN backup or restore RMAN process?

  Kind regards

  007

  To accelerate a datapump export market and import you can attach to employment and increase the level of parallelism... impdp attach = job

  I don't know any way to speed up a running RMAN backup.

  To expedite an RMAN restore, you can kill the restoration and re - run using several channels.  The restoration should take up where he left off and can run faster with many channels.  It is relevant only if you have several items from backup.

• expdp/impdp: constraints in the child-Parent relationship

  Hello
  
  I have a table parent1 and child1, child2 and chld3 tables have foreign key created on this parent1.
  
  Now, I want to do a delete on parent1. But as the number of records is very high on parent1, we go with expdp / impdp with option querry.
  
  I took the expdp parent1 level query. Now I dropped parent1 with option of cascade constraints and all foreign keys created by child1, 2 and 3 that parent1 references are automatically deleted.
  
  Now, if I have the impdp to the query of fire level dump file, are these foreign key constraints will be created automatically on child1, 2 and 3 or I need to manually recreate it?
  
  Kind regards

  Hello
  The CF will not be in the dumpfile - see the code example below where I generate a sqlfile following pretty much the process that you would have done. This is because FK belongs to the DDL for the child table not the parent.

  I do not. You must upgrade, and then convert the characters or convert then upgrade - you can save an SR to confirm this with the support of the Oracle.

  Only DBUA is the way supported in Oracle EBS instance level. Please see this similar thread - Oracle EBS 11i Database Upgrade to 11 GR 2 - Upgrade method Support Manual is?

• IMP/exp expdp/impdp vs

  Hi all;
  which is better in performance the traditional exp/imp or expdp/impdp?

  Hello

  Oracle Data Pump is a more recent, rapid and flexible alternative to utilities 'exp' and 'imp' used in previous versions of Oracle. In addition to export and import of basic feature data pump provides a PL/SQL API and support for external tables

  If Oracle is recommended for all 10g databases and more use of Data Pump and pre 10g use old exp/imp :)

• expdp, impdp in 12 c and 10g

  Hi all

  We have oracle 10g release 2 on windows environment. We want to take backup of this database using expdp and import it into oracle 12 c using impdp.

  How to do this?

  I use the following approach

  on 10g database (production):

  expdp complete system/password@orcl directory = y = TEST_DIR dumpfile = fulldb_12_jan_2016.dmp logfile = fulldb_12_jan_2016.log

  on 12 c database (test):

  Impdp complete system/password@orcl directory = y = TEST_DIR dumpfile = fulldb_12_jan_2016.dmp logfile = fulldb_12_jan_2016.log

  the problem is that we need to create storage space and data files. I already create their production before the impdp command.

  second problem is that the user schemas have quota on the tablespace. So I have to create users as well before the impdp? I don't know some of the passwords of the user schema.

  Please guide me

  Thank you.

  Hello

  Since you are doing the full expdp, users and tablesapces will be created for you.

  So no need to creaet them pre.

  Concerning tablespaces, impdp will try to create storage space with the same data files (eg - same location of files).

  So, if you do not have same directory on the destination structure it will fail.

  If the file structure is different you can pre create tablespaces and remap the data files using remap_datafile.

  Users will be created with the same passwords on the destination. It is so no worries.

• EXPDP/IMPDP

  Hi all

  How do I create a sqlfile using impdp so to run it so that the procedures will be replaced by the more recent source expdp database.

  But the sqlfile a bug that include spaces in the sql statements, the cause of the error.

  For example:

  ALTER PROCEDURE "BATCH". "" SP_COUNT_DLS_DRCR ".

  COMPILE

  PLSQL_OPTIMIZE_LEVEL = 2

  PLSQL_CODE_TYPE = INTERPRETER

  PLSQL_DEBUG = FALSE PLSCOPE_SETTINGS = ' IDENTIFIERS: NO

  "REUSE THE TIMESTAMP SETTINGS ' 2014-01-10 10:12:26.

  /

  It has a space before RE-USE, where the script error on RE-USE statement

  Tricks treats on this subject?

  Thank you very much

  Hello

  Yep - thought I'm sorry that you had made only empty lines and that was the problem :-)

  The empty sqlfile option just what import tries to run text - so it just remains to create instead of replace.

  What you have to do is change the file and do a global replace of 'CREATE' with 'CREATE or REPLACE '...

  Still don't know why oracle did not add this as an option - it is one of the main things missing impdp - perhaps there is a technical reason why they do not want to implement?

  See you soon,.

• Table view is different in expdp/impdp?

  11.2 / Linux
  
  With exp/imp original: OWNER, TABLES and FULL modes are mutually exclusive. IE in original exp, if you want to make a backup of the EMP table in the scott schema, the following will be error
  

  exp / tables= EMP owner=SCOTT file=selected_tables.dmp log=selected_tables.log
  
  But this will end up in
  EXP-00026: conflicting modes specified
  EXP-00000: Export terminated unsuccessfully

  You must prefix the name of the owner (tables = < owner >. < table_name >) as below for the prescription above
  

  exp / tables= SCOTT.EMP file=selected_tables.dmp log=selected_tables.log

  But in impdp things work differently
  
  I provided a dump expdp of REG_TRACK_EVT of a CLS_USR_PROD scheme. I wanted to import that table in the schema of development CLS_USR_DEV. So, I did. But launch error ORA - 39166 TI kept as below
  

  $ impdp userid=\'/ as sysdba\' DIRECTORY=DPUMP_DIR DUMPFILE= reg_track_evt.dmp LOGFILE=reg_track_evt-imp.log tables=CLS_USR_DEV.REG_TRACK_EVT

  ORA-39002: invalid operation
  ORA-39166: Object CLS_USR_DEV.REG_TRACK_EVT was not found.

  To solve this problem, I had to remove the parameter TABLES (!) and use the REMAP_SCHEMA parameter

  impdp userid=\'/ as sysdba\' DIRECTORY=DPUMP_DIR DUMPFILE= reg_track_evt.dmp LOGFILE=reg_track_evt-imp.log REMAP_SCHEMA=CLS_USR_PROD:CLS_USR_DEV

  If this is the case, then what's the point of having the TABLES parameter in impdp?

  It's really the same thing regarding conflicting modes. Of what you have used in your import command:

  Impdp userid =------"/ ACE sysdba\ ' DIRECTORY = DUMPFILE DPUMP_DIR = LOGFILE reg_track_evt.dmp = reg_track_evt - imp.log REMAP_SCHEMA = CLS_USR_PROD:CLS_USR_DEV

  If you are remapping CLS_USR_PROD:CLS_USR_DEV then the table in the dumpfile is called CLS_USR_PROD. REG_TRACK_EVT and you tried to import CLS_USR_DEV. REG_TRACK_EVT and this table did not exist.

  What you specify on the tables = command is the table in the desired dumpfile. What you specify in the remapping of the color settings is where you want the table created, therefore, your first order was close, you need this:

  Impdp userid =------"/ ACE sysdba\ ' DIRECTORY = DUMPFILE DPUMP_DIR = LOGFILE reg_track_evt.dmp = reg_track_evt - imp.log tables = CLS_USR_PROD. REG_TRACK_EVT REMAP_SCHEMA = CLS_USR_PROD:CLS_USR_DEV

  I hope this helps.

• Error: ORA-02429 after using expdp/impdp

  Hi all
  I have a problem: when I save my 11g database and restore the database to another name I can't drop specific index.
  I get this error: ORA-02429: cannot delete the index used for the application of unique primary key.
  
  Note: I can easily delete this index before I run backup/restore procedures.
  Here are the steps.
  
  (1) creation of database D1
  (2) Save:
  expdp * schemas = D1 dumpfile = D1.dmp logfile = D1.log *.
  (3) create a new db user
  CREATE A USER IDENTIFIED BY D2 D2...
  (4) restoration of D1 to D2:
  Impdp D1/D1* remap_schema = D1: D2 dumpfile = D1.dmp *.
  (5) at this point, I'm getting another identical database D2. but for some reason, I can't drop some clues as described above.
  
  Any ideas what Miss me in the process. No impdp/expdp modifing my databes somehow?
  
  Thank you very much.

  Ok
  You can do the following

  1. disable all constraints.
  2 create a script to drop and re-create the index
  3 delete the index
  4 turn off the constraints of
  5 impdp CONTENT = DATA_ONLY
  6. run the script to create indexes
  7. activate the constraints
  8 activate triggers

• How replicates all records from one table to another table without using expdp, impdp

  Hi I have two database in a database, that I have a table called t1 and another base data, I have the second table .so, my first table have records, that I need to transfer all records second T2 without use of expdp and impdp in every 5 min... what I do

  ??

  The best solution for this scenario is to use Oracle Golden Gate

  However, it requires a license, and you must pay for it.

  If this is not possible, you can create a job scheduler that uses a link DB in order to reproduce the recordings of the target database, but it will take the entire table to the target database and then INSERT AS SELECT truncate the data of the entire table every time that the job is running (because you can't follow only the records that have been changed or modified).

  In addition, read here on the replication of data using materialized views.

• expdp, impdp - redo generation?

  Friends...

  Oracle 11 g 2 SE

  OS: Linux

  I had tried to search in the documentation, but could not find an answer.

  I'm dropping some tables but prior to export for backup, db is in archivelog mode.

  Before you delete tables, trying to find if expdp job generates a lot of repeat or not given that the file system have 20 GB of free space.

  Issue.

  1. If I'm the scene expdp some tables with size 80 GB (size.. indexes on table not included), does expdp will generate a similar amount of redo or it will generate a lot of repeat?

  2 impdp job also generate a lot of repeat or only during the creation of index in impdp?

  Thank you

  Mike

  Export do NOT generate all over again. It's just dumping data in binary files. Very little again just to keep the export data table, rocking but very very minimal. IF I had to guess not more than 1 MB.

  Import generates recovery logs. Imports perform "Insert" statement behind the scenes and it does not generate a lot of newspapers of recovery. You can use sqlfile to create the definition of the index and to run manually with NOLOGGING which will reduce some redo. something like

  exclude the user/password Impdp = index - this will import everything except the index.

  Impdp username/password include sqlfile = index.sql index = - this will create a file named index.sql that will contain all the instructions for the index create
