• exp/expdp of 32-bit, and then imp/impdp 9i to 11 GR 2 64-bit

  Hi all

  This process is supported?

  exp/expdp of 32-bit, and then imp/impdp 9i to 11 GR 2 64-bit

  Thank you very much

  Hi, Jenna.

  Yes, it is supported.

  Import/export is done at the level of the data files OS no not really something to do with the system, the data files are the same regardless of the oracle software binary level. However, you should check if any problem with the compatibility of data on levels of oracle version.

  But please make sure that you use the same utility dump file, i.e., imp - exp and expdp-impdp(introduced from 10g)

  Thank you

• Impdp fails via data link

  Hello
  
  I am trying to import a particular schema of another instance in my instance via a link of database using Data Pump.
  
  Source instance: Solaris on Sparc 10.2.0.4.0 64-bit
  Instance of the target: Linux on x 32, 10.2.0.4.0
  
  I created a database on the target database link and checked the link to work, i.e. I could query the tables in the remote database by using the user who should receive the data.
  
  I created a directory "exp" on the target database and have the appropriate permissions for 'mh03.
  
  Then I tried importing and got an error:
  
  -----
  
  Oracle@padsw7ora01 imp$ impdp mh03 / * NETWORK_LINK = padsol25 = test_bas_bkrus_d123120 REMAP_SCHEMA = test_bas_bkrus_d123120:mh03 = exp = imp.log LOGFILE DIRECTORY SCHEMAS

  I tried searching metalink and web but not able to find any useful information. I tried using the VERSION = '10.2.0.4.0' parameter, but this did not help either (error message remains as what).
  
  I found what seemed somewhat related:
  
  ORA-39113: unable to determine the database version
  Cause: The Data Pump has been impossible to determine the level of compatibility with the version of the current database using SYS. DBMS_UTILITY. DB_VERSION.
  Action: Be sure you have access to the DBMS_UTILITY package for you. If it is a network work, make sure that package DBMS_UTILITY access is granted to you on the remote instance.
  
  But even that "grant execute on SYS. DBMS_UTILITY to mh03' did not help at all.
  
  I realize that the target database is compatible to 10.2.0.3.0:
  
  -----

  2 v varchar2 (1000 char);
  VARCHAR2 (1000 char) 3 c.

  In my case it had nothing to do with the host name of the server, or name resolution. It was related to the global_name of the instance.
  I could question using the link but not to perform a remote import.

  Try to temporarily change your global_name by removing the hyphen in domain name and test your import:
  SQL > alter database rename global_name to .pad. * mycompany * .net.

• When I do exp (expdp), why use the temporary tablespace?

  Dear

  Imp (impdp) is using temporary tablespace.

  but I'm not using tablespace temp, while exp (expdp) is running.

  I think that exp (expdp) will not use temporary tablespace. is it not?

  Please let me know?

  He could.  It must run queries on the data dictionary.  Some of these applications may require the temp tablespace.

• Extraction of the DDL (Code) of the stored procedures only

  DB Version: 11 g
  
  I have a list of stored procedures (about 250) whose code IE. Statements to CREATE or REPLACE STORED PROCEDURE I want to extract a file.

  Apart from the imp/impdp, is there another way to do this?

  Is there an option in imp or impdp where I can extract only the code of these stored procedures?

  Impdp, Yes. Write the contents of a file, the option SQLFILE.

  DUMPFILE = exp.dmp
  LOGFILE = exp.log
  SCHEMAS = TEST
  INCLUDE = PROCEDURE: 'IN ("SP") '.
  SQLFILE = sp... SQL

• 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.

• Jobs impdp/imp consumes UNDO tablespace

  DB version: 11.2.0.3
  Version of the OS: RHEL 5.6
  
  I'm doing an import of single table which is 7.5 GB in size. It takes more than 35 minutes with PARALLEL = 3.
  Free space of the tablespace Undo was only 100 MB when I checked. Temporary tablespace had 3 GB of free space.
  IMP or impdp process consumes well CANCEL? Impdp no insertions using plain INSERT SQLs internally?

  Yes, cancellation can be consumed, even more in impdp as IMP. But what really depends on used options, look so _session_wait and events tables of $ v. Some versions (I'm not your) have had problems when there are many objects, dealing with the ddl.

• 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 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.

  Hi H. Christy

  As you mentioned in the previous post, your database schema source GSW has segments in the following storage spaces;

  SQL > select tablespace_name distinct from dba_segments where owner = 'GSW ';

  TABLESPACE_NAME

  ------------------------------

  USERS

  SYSTEM

  When you import, you specify:

  REMAP_TABLESPACE = SYSTEM: GSW

  But the import process fails with:

  ORA-39083: TABLE object type: 'GSW '. "' REPORTS ' unable to create with the error:

  ORA-00959: tablespace 'GSW' does not exist

  Above means GSW tablespace must be created in the target database because you specify that all segments of the SYSTEM tablespace must be redirected (created) in tablespace GSW.

  Also, you must rewrite your import like this command:

  Impdp gsw/pass remap_tablespace = SYSTEM: GSW remap_tablespace = the rΘpertoire of USERS: GSW dumpfile = gsw.dmp = dmpdir

  Then, you must restart all import process in the target database:

  SQL> CREATE TABLESPACE gsw .......
  
  SQL> drop user gsw cascade;
  SQL> create user gsw identified by pass;
  SQL> grant connect, resource to gsw;
  SQL> grant read, write on directory dmpdir to gsw;
  SQL> grant create database link to gsw;
  
  impdp gsw/pass remap_tablespace=SYSTEM:GSW remap_tablespace=USERS:GSW dumpfile=gsw.dmp directory=dmpdir

• Could not import the database using impdp via network_link

  Dear all,

  I'm trying to import the database from the remote location to my local database dump after you have created the dblink to local db db remotely.

  Help or advice would be really appreciated.

  Hi Syed,

  I think you do the opposite on the directory stuff.

  The directory parameter is just to hold the log file. There is no file dumpfile required in IMPDP via dblink operations it's all cross-network.

  Basically, what is lacking is the DIRECTORY on the local server.

  Don't forget not also create the associated tablespace and remap if necessary.

  Kind regards
