• 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

  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.

• 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

  JC

  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

• 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.

• 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.

• Add data using EXPDP/IMPDP

  I have a log table that is daily exported and imported to another schema. what I do currently, export the LOG table, delete the existing table of NEWSPAPER on the target schema, and then import in there.

• Migrate EXP EXPDP discontinuous systems app

  Hi all

  11.2.0.1

  AIX 6.1

  We are forced to migrate our batch processing EXP EXPDP system due to the implementation of the vault of the database and encryption (TDE) data Transparent.

  Our dilemma is the property of files/folder EXPDP systems is "oracle: dba" while existing filesystems EXP file belongs to the "batchuser:batch". There will be a lot of major changes when it comes to backup

  treatment if we are implementing that. Is there a way that an EXPDP folder can still be owned by "batchuser:batch"?

  Helppppp pleasee...

  I presented the traditional backup our APP lot EXP system changes, there was a backlash of the operations group because there will be many changes to batchprocess.

  The major issue and

  the main change is the APP folder "/ discharge/batch/u07 ' who is currently owned by"batchuser:batch"placeholder and the dump of the exp for daily or monthly operating tables, change belonging to" oracle: dba "and operating group do not allow this change. Is it possible that the directory_dump_dir can be owned by other than the oracle user?

  Thank you

  HELP ME PLEASE

  Since you're using Oracle 10 g version...

  Check if you have columns that contain "TEMESTAMP (6) ' data by using this query type:"

  Select dba_tab_columns owner, table_name, column_name data_type where column_name = 'TIMESTAMP' and data_type like '% TIMESTAMP ';

  If the previous query lists for you a list of tables, you must do the following for each table:

  ALTER table system.table_name change (date timestamp);

  Then recompile the package "DBMS_INTERNAL_LOGSTDBY" again.

  I hope this helps.

• 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.

• 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.

• language of stdout IMP/exp

  Hi all
  
  I'm interested in changing language exp or imp log files? Oracle version is 10.2.0.4.0, version of the OS is Win 2k3R2.
  
  I have Oracle DB installed on the OS of the Hungarian language and when starts a command exp, I get the log on the Hungarian language file. I need language stdout for utility imp/exp on English. Can I do this?
  For as far as I know language stdout to query for the current session sqlplus can be changed with alter session set nls_language = ENGLISH.
  
  A little demonstration:
  
  current log file:

  . . . . .
  . . a következo tábla exportálása:                         A          3 sor exportálva
  . . a következo tábla exportálása:                         B          2 sor exportálva
  . . a következo tábla exportálása:                         C          0 sor exportálva
  . . . . . 

  desired logfile:

   . . . . .
  . . exporting table                       A          3 rows exported
  . . exporting table                       B          2 rows exported
  . . exporting table                       C          0 rows exported
  . . . . .

  TNX in advance.

  Before walking exp or imp (and why use exp and imp?)

  Set nls_lang =_.

  Don't know why but it seems that it is "Question Doc day" again.

• Expdp/impdp can be used to upgrade the database (instead of DBUA) R12

  Hi all
  
  (1) could as possible to convert the database to UTF8 value as part of the database
  upgrading process within the update Rel12? Any suggestion on how to do it? Any doc doc/procedure?
  
  (2) according to Rel 12 guide upgrade applications, I can follow "interoperability Notes: Oracle Applications 11i.
  with Oracle Database 11 g 2"doc to update my database. But this doc suggested using DBUA.
  Can I use expdp/impdp instead so I can convert the character at a time? All documentation
  that I can follow to use expdp/impdp to do the upgrade?
  
  (3) are there measures to specify/extra for Rel12 if I want to convert the characters of the base
  the value UTF8?
  
  Thanks in advance!

  (1) could as possible to convert the database to UTF8 value as part of the database
  upgrading process within the update Rel12? Any suggestion on how to do it? Any doc doc/procedure?

  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.

  (2) according to Rel 12 guide upgrade applications, I can follow "interoperability Notes: Oracle Applications 11i.
  with Oracle Database 11 g 2"doc to update my database. But this doc suggested using DBUA.
  Can I use expdp/impdp instead so I can convert the character at a time? All documentation
  that I can follow to use expdp/impdp to do the upgrade?

  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?

  (3) are there measures to specify/extra for Rel12 if I want to convert the characters of the base
  the value UTF8?

• imp exp/full FUL grant allows select u / drop all tables... How to avoid this?

  Hi all
  
  We do nightly exp as our backup for certain pattern... and shell script we used the password hardcoded in the script system and we want to avoid this... so I try to create another user who can make exp/IMP... and what's my user statement like... to give full grant create imp exp/full...
  
  CREATE test USER
  IDENTIFIED BY THE VALUES OF 'PASS '.
  DEFAULT TABLESPACE USERS
  TEMPORARY TEMP TABLESPACE
  DEFAULT PROFILE
  RELEASE OF ACCOUNT;
  -3 roles for test
  GRANT IMP_FULL_DATABASE TO test.
  GRANT CONNECT TO test;
  GRANT permission TO test;
  Test of ALTER USER DEFAULT ROLE;
  -1 privilege system for test
  GRANT UNLIMITED TABLESPACE TO test;
  
  but now, here's the thing... This test user is able to query every single table in any schema... or drop something... . How can I stop that...
  
  all I want to do for test user is exp/imp and nothing else... the user can select on any table but cannot modify or drop whatever it is... what according to give for it? some exp/IMP...
  
  If not, how can I avoid hard codding the password in my shell script? Can I have one parfile but then again who will need to have the password... and we try to avoid that...

  Anyone (with the appropriate privileges) can import the dump file later. You wouldn't need the TEST user to be able to import the file. If the only thing that the TEST user generates a FULL dump file = a, then the user would only need permission privileges. If the user does not have a full export because you're that concerned about a few diagrams, the user didn't even need permission privileges.
