Commit IMPDP = parameter y?

Hi all

Validation = y in old exp helped me a lot when I have little space allocated to cancel the TS.

I can't believe that it is deprecated in EXPDP? Is this true?

I'll take 100 GB size of discharge and I have only few as 120G disk space. How can I avoid the snapshot too old mistakes?


Thank you very much

Kinz

You started your validation question = y, then you were asked "how much space I allocate to him when it will be imported? It will be multiplied by 2? or 3 times? ", and now you ask on insert and rollback. Please do not mix/mess issue, stay on one, so that we can try our best to give you the right answer.

If you ask how to estimate the size of the dump file, and then use estimate_only = o with expdp command. This indicates that you estimated the size of the export dump. Size real dumpfile will be lower than those reported by the parameter estimate_only. But if you ask how long it will take, I think that its another issue for a new thread. But yes I do not know his answer.

But your question is:

How much space will allocate to him when it will be imported? It will be multiplied by 2? or 3 times?

Then read below thread:
Impdp: = estimated size diagram

For the next issue, please open a new thread. Close this, if you have any other answer continue to question only.

    even the precompression of tablespace also not worked

    Of course it won't. But first, it is not the precompression, even that is not 'do the compressed tablespace' Dean said. She does by DEFAULT for any object created in this table space. If you set the tablespace default storage COMPRESS parameter and create a table in this tablespace without specifying explicitly COMPRESS or NOCOMPRESS table will inherit settings COMPRESS the default tablespace default storage. However, if d definition explicitly states NOCOMPRESS it will replace the default tablespace storage parameter COMPRESSES and will not be compressed. And when you export a table all THE attributes of the table are exported. If exported table is not compressed, export dump file contains the table definition which States explicitly NOCOMPRESS and import the dump file will be important table being NOCOMPRESS any default tablespace.
    Now how can solve you this problem. Problem importing with CONTENT = parameter METADATA_ONLY. It will import all the data but will just create all the objects. Then, for each imported (without data) issue table ALTER TABLE tbl COMPRESS. For ALTER INDEX REBUILD COMPRESS ind index number. Keep in mind, not all the clues can be compressed and for indexes partitioned, you may need to delete the index and recreate it as compressed. Now add impdp parameter TABLE_EXISTS_ACTION = APPEND and import. Obviously the import log will have errors like:

    ORA-39152: Table "XXX"."XXX" exists. Data will be appended to existing table
but all dependent metadata will be skipped due to table_exists_action of append

    which can be ignored.

  • Using 'text field contains comma-separated values' on a parameter of %

    Hello

    I use a parameter that has more than one value to be entered, separated by commas. I checked the box 'text field contains values separated by commas' for the parameter and set the sql code by using the operator 'in' so that the column will look in the multiple input values (e.g. family name in (: surname_par)). However, as passing multiple values parameter must also be able to manage %'s. As the sql uses the 'in' operator, BI Publisher brings back an error because % is supposed to bring all family names and not people with a last name of %. Is there a way to get around this?

    Thank you

    If you try to pass multiple values separated by commas and in addition also takes the query to return the data when the user types just in '%', then you could write something like this in your query:

    Select * from table_name
    where ((1 = DECODE (: surname_par, '%', 1, 0)) OR family name in (: surname_par))

    I hope this helps. Please award points if helpful/correct.

  • Impdp sqlfile parameter

    Hello

    OPERATING SYSTEM: HP - UX
    Oracle10g

    My production dba team sent me a sqlfile comprising 30K tables. They used sqlfile = parameter to get the DDL of the tables. I need to create the same DDL commands on my dev database.

    My thought is rather than generate the ddl sqlfile orders and recreate all the ddl in the dev environment.
    Why not to use the command to create structures of table below...

    leader lines = abc.dmp user/pwd = n = aabb log patterns exp = abc.log

    Would not be in the above given command creates all the structures of table (DDL)?

    They are right for which one needs the sqlfile parameter take all DDLS and manually create?

    Also pls inform me the importance of the sqlfile parameter in expdp/impdp...


    Thank you
    KSG

    Published by: KSG on March 25, 2010 10:51

    My understanding is... After you run the impdp command, a sqlfile will be generated which contains the dumpfile DDL commands relavent. I'm good with that?

    Yes. It is somewhat similar to show = Yes command in imp

    And I want to run the script to create the DDL...

    Another is my doubt...

    It's a hard way to create all the DDL by using the sql script file?

    Why should I not go and take an export of all the table structure to help

    expdp user/pwd file = dumpfile.dmp lines = n = abc log owner = dumpfile.log

    and just import the dumpfile.dmp... Woundn can't create this all the DDL as long as same as the generation of the sqlfile script?

    It depends on the rquirement. lets see you want to exclude a few tables full dump for the creation of the structure, sqlfile will come handy.
    not sure what all the objects in your dump file are made up and you want to see the content (objects) of the dump file, instead of imporing to the database and check then you will be able to access it without actually importing. You can use lines = n only when you are sure and import the entire structure of the objects.

    If the dumpfile has schema1 and schema2 want, then you have to a remap_schema = schema1:schema2

    The above-mentioned remap table will not work.  You can't remap a pattern with a remap_table parameter.

  • User header imported successfully, Impdp import the same user has: b getting object exists error

    ORA-39151: Table "A.Table_Name" exists

    Seems for some reason any your part of remap_schema is not recognized.

    In the beginning of the impdp log, you should see the command it uses,

 insert into emp values (6,'xyz',50,1000,'e avenue');
 commit;

    I need assistance with a procedure. Here are the requirements.

    (i) the user can input parameter value for 'EMPLOYEE' as a NUMBER, or a VARCHAR. For example 1 or 'ABC '.
    (II) based on the input value, the procedure should return the desired folder. For example

    select * from emp where id=1 or select * from emp where name like 'abc'

    (III) all columns can be used as parameters to pass values for example CREATE PROCEDURE p_emp (OFFICIAL, DEPARTMENT, SALARY, ADDRESS, FILTER)
    (IV) not succeeded a few values of some parameters is acceptable for example exec p_emp('',10,1000,'')
    (v) output (OUT) should be a table format (I think that maybe SYS_REFCURSOR can be used) for example

    1 ABC 10 1000 A Avenue
    4 JKL 10 1000 D Avenue

    (VI) result (OUT) can be controlled by ROWNUMBER for example.

    select * from emp where rownum between 1 and 3

    If none is specified, then first 2000 records are represented.
    (VII) an additional parameter (FILTER) must determine what output result should look like. For example. If 1 then went only to show ID, NAME, if 2 is passed to see the ID and ADDRESS etc.

  • In passing the huge parameter to oracle procedure have a performance hit?

    I have a script attached, in which I am trying process/XML parsing in a table (STAGE_TBL) in the XMLTYPE column and insert the data analyzed in another table (PROCESSED_DATA_TBL).

    The issue I see is when I pass an XML object to a procedure (STAGE_TBL_PROCESS) to analyze its takes about 10 seconds per XML, but rather than from XML if I directly pick up table in the procedure (STAGE_TBL_PROCESS) passing the ID to be about 0.15 seconds.

    In version 11.1, Oracle introduced a new model of storage for the data type XMLType called XML binary.

    Binary XML become the default in 11.2.0.2, to disparage the old storage based on CLOB.

    Binary XML is a format optimized after analysis for the storage and treatment of the XQuery.

    When an XQuery expression is evaluated (through for example XMLTABLE) on an XMLType column stored as binary XML, Oracle can use an ongoing evaluation of XPath that surpasses the query even crushed a transitional XMLType of several order of magnitude.

    You can see that in the action plan of the explain command:

    SQL> SELECT E.*
  2  FROM stage_tbl t
  3     , XMLTABLE('rp_send/rp_sendRow' PASSING t.xml_document
  4         COLUMNS store VARCHAR(20) PATH 'store'
  5               , SalesNo VARCHAR(20) PATH 'sales'
  6               , UnitCost NUMBER PATH 'cost'
  7         ) E ;

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

    When the query is executed on a passenger XMLType (for example, a parameter, or a PL/SQL variable), Oracle cannot run the binary model and use a functional assessment based on memory of the XML DOM-like representation.

    You can see that in the plan to explain it by spoting a 'COLLECTION ITERATOR PICKLER FETCH' operation.

    So what explains the difference (in your version) between treatment from a column of XMLType (stored in binary XML format) or a variable or a parameter.

    From 11.2.0.4 and beyond, things have changed a bit with Oracle, introducing a new transitional level of optimization on XMLType.

    The plan of the explain command will show a "XMLTABLE ASSESSMENT' in this case.

  • file system to archive &amp; impdp

    After the upgrade of a database of GR 11, 2 to 12cR1 (12.1.0.2), I noticed that whenever I run impdpd to import data, the journal file system archive fills up very fast and consumes the whole file system which stops the impdp treat.

    one of the solutions, I discovered is the stop of the database and run it in "no archive log", then I re - run impdp again.

    any suggestions?

    I don't think that the upgrade of your database has a relationship with your problem you have described. one of the things you need to do is to increase the size of your file system of the journal of the archives.

    Also, a new parameter introduced in release 12 c "transform = disable_archive_logging:y" use it in your impdp command (archives less will be generated and its more quickly by importing data).

    I hope this helps.

  • How to switch the input of command in the DAL script parameter

    Hello guys,.

    I want to pass the name to extract xml (one of the input for the batch of documaker parameter) to one of my trigger DAL.

    I plan to use the Ext2GVM function for this. I need to know the syntax of the following parameters:

    Say-exporter variable XMLNAME am for the batch.


    (1) what should be of syntax for the AFGJOB file

    Is this correct-> ; Ext2Gvm; 2; ParameterName = ~ GETENV XMLNAME ;

    (2) what should be my entry in the trndfdfl. DFD

    Is this correct->

    < FIELD: parametername>

    EXT_LENGTH = 21

    EXT_TYPE = CHAR_ARRAY_NO_NULL_TERM

    INT_LENGTH = 20

    INT_TYPE = CHAR_ARRAY

    KEY = O

    REQUIRED = Y

    FIELDNAME = parametername


    (3) is it necessary to go into details as < Trn_Fields > in the ini files?

    If so, please help me with sytnax


    (4) final, how can I call this variable in the script DAL ?

    Is this-> OK

    Metafilename = GVM ('parametername')


    Thank you


    I reformulerai what I think you do.

    You have a file name that you want to reference it in a script DAL. This file is NOT the snippet file should be able to use in the creation and mapping of your transactional data, but a few additional files that you expect to process directly from DAL.

    If this is correct, two possibilities come to mind.

    1. assuming it's a file that you can copy using your linux script, copy the file to a consistent name. Your script DAL can then use the code name hard you still copied.

    2. a method that does not have a copy of the file would require that you create an environment variable of the linux script that contains the name of the file passed. In your INI, you must define your own INI, something like this:

    Filename = ~ GetEnv MyExternalFile

    The DAL script would do this to get the name:

    xmlFileName = GetINIString ("MyINIGroup", "Filename");

    When DAL is requesting the INI value, see the logic underlying the ~ GetEnv which is a built-in function to get the environment variable named following. So if you have assigned your script linux environment variables, the name going through now and DAL has a way to get it.

    (Note there is no magic in the name of the INI option or group or the name of variable environment you choose to use.) The magic is to use the ~ GetEnv to retrieve the value of the environment when the option is requested.)

    Second note, the GetINIString function has an optional first parameter to name a context INI. In this case, I do not pretend that you use this setting. Just include a comma to indicate that the first parameter is omitted.)
