• Export and import using named pipes

  Hai,
  I need a clarification to the export, import and compress dumps using named pipes. I use Oracle 9i RAC 9.2.0.4 in AIX 5.3. Every month I have to move the list of tables in a database to a different database after shocks of export. The list of activities made by me at the present time are given below.
  
  1 account export and gziping file dump at the same time by using named pipes.
  2. to unzip and import into database using named pipes second.
  
  We do the compress for space constraints. Now my doubt is if using named pipes, we can make two import operations and compress the dump file at the same time. That is to say, at the time of export, using channels named, I need the import into the database in another and compress the zip file. Is this possible?

  mknod exp.out p
  mknod imp.inp p

• expdp using network_link (link not valid name)

  Hi all

  I have 2 database in the same host, namely SLAVE_PORT_NUM and orcl.

  I want to execute data expdp orcl on a network_link to the location of the directory of slave_port_num.  (expdp is executed in slave_port_num)

  On the source database

  
  

  PUMPUSE@ORCL 26 Aug 15 21:31:58 > display the db_name parameter

  VALUE OF TYPE NAME

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

  db_name string orcl

  PUMPUSE@ORCL 26 Aug 15 21:47:15 > show user

  The USER is 'PUMPUSE'-'r '.

  PUMPUSE@ORCL 26 Aug 15 21:45:01 > select * from test;

  A

  ----------

  1

  On the basis of data target.

  PUMPUSER@orcl3 26 Aug 15 21:42:32 > display the db_name parameter

  VALUE OF TYPE NAME

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

  db_name string SLAVE_PORT_NUM

  PUMPUSER@orcl3 26 Aug 15 21:53:02 > show user

  The USER is "PUMPUSER" - with an 'r' to the difference in the source database

  [oracle@SJOAM path] $ tnsping orcl

  Use settings files:

  /U01/app/grid/product/11.2.0.4/grid/network/admin/SQLNET.ora

  Try to contact (description = (address_list = (address = (protocol = TCP)(host=SJOAM.oracleszejie.com) (PORT = 1521))) (connect_data = (service_name = main.oracleszejie.com)))

  OK (0 msec)

  PUMPUSER@orcl3 26 Aug 15 21:48:30 > select * from user_db_links;

  no selected line

  Database link created.

  PUMPUSER@orcl3 26 Aug 15 21:49:05 > select * from test@orcl;

  With the database link "orcl" working on the db (slave_port_num) of the target, I issue the following

  [oracle@SJOAM path] $ expdp pumpuser/abc123 network_link = orcl dumpfile = orcl.dmp = logfile = export.log export directory

  Why it does not work when you use expdp, but when inside the database, select by using the link "orcl" works of db.

  YES, YOU ARE EXACTLY RIGHT.  This is used if often it is supported.  I see 2 reasons why you want to do that while I type.

  1. you want to unload the source database and the target database is going to do some work for export on a running target database will unload everything from writing to the dumpfiles, by writing to the main table, etc.

  2. If your source database is read-only, so you cannot run Data Pump export on this as Data Pump creates a table and writes in this table.  If you have a different database, for example target a database, you can run expdp on it, because it is read-only and the source database cannot be read from.

  So yes, you can do it.  I don't know what the problem with your dblink, but it works and is supported.

  The Quick Start guide is a diagram showing how to insert a Micro SD card, this indicates that the cover is removed to expose the Micro SD slot, and once the map is in place, you replace the end cover.

• Re: 10.2.0.3 dump EXPDP to 10.2.0.4 IMPDP - compatibility

  Export a database on Oracle 10.2.0.3 datapump. This discharge would be compatible for IMPDP with a database of Oracle 10.2.0.4 on another server? OR atleast 10.2.0.4 database is necessary on the other server to import?
  The COMPATIBLE db setting is the same for the two databases.
  
  Thank you.

  You release will work on 10.2.0.4 impdp.

  utility export must be version lower or same version of the import utility. In case you're.

  Unlike the classic export the datapump isn't is no longer in charge of piping, use the COMPRESSION parameter instead:

• Is it possible to know which parameter when used during expdp?

  Hi experts,

  I got a dump expdp from a client file, but usually, he forgot to include the LOG file.

  Is it possible to know what settings when used during expdp? I am particularly interested on the QUERY parameters and EXCLUDE because I think that he "forgot" to include tables that are needed.

  Thank you

  Jose Ramon.

• PPC WITH PIPE

  Is it possible to use expdp hoses?
  
  I try with this code...
  
  ********************
  mknod exp_pipe p
  chmod 666 exp_pipe
  compress the < exp_pipe > expdp_PRE.dmp.Z &
  
  # POR IF WE WANT TO RUN A SPECIAL EXPORT
  expdp SYSTEM = directory = TEST_DIR = exp_pipe = expdp_PRE.log = STATISTICS EXCLUDE logfile dumpfile < < EOF
  mypass
  FO %
  ***********************
  
  Thanks in advance for your answer.

  Unlike the previous exp/imp utilities, where all the IO files has been done at the client level, Data Pump makes all its IO files on the server. Pipes cannot be used with Data Pump. Two of the most common reasons for the use of pipes are to compress and encrypt a dump file. Data pump now offers both of these features as online operations.

  From 10.2 Data Pump Export compressed metadata system (but not the table data) written in a dump file. This is the default behavior and functionality is free.

  11.1 data Pump provided full dump file compression (that is, the two metadata system and data table) but also encryption of full dump file. However, the compression of the data in the table or by using the dump file encryption requires Enterprise Edition licenses as well as the Advanced Compression and Security Options Advanced.

  An example of use of the compression feature might look like this:

  expdp directory with name of user and password = dpump_dir dumpfile = full full = y = all compression

  That would compress all data written to the dump file. No special setting is needed to import a compressed dump file.

• expdp - name problem

  Hello guys,.
  
  I use Oracle Database 11.2.0.2.0.
  
  Well, I'm trying to generate a dump using utility expdp. Here's him parfile:
  
  UserID = "/ as sysdba".
  Full = Yes
  dumpfile=expdp_vvp_full_00%U.dmp
  logfile = vvp_full.log
  job_name = jb_vvp_full
  parallel = 4
  file size = 10G
  Backup_dir = directory
  compression = metadata_only
  
  I understand that the parameter ' parallel = 4' working with the parameter "= 10G file size ' will build the dump in 4 10 GB files each [the last of them can be smaller]."
  
  I updated this place everyday in the crontab: worked today, but tomorrow it will tell that the file already exists and will not discharge.
  
  I tried to change the name like this: expdp_vvp_full_00%U%d%m.dmp
  
  But these '%m %d' did not recognize expdp [but in utility exp, it works],
  
  You guys have any advice to help me with this problem?
  
  Thank you.

  Hello

  When you say sqlplus works how you connect - expdp uses the same process of connection so if we work the other should too.

  you do sqlplus user/pass@db

  and expdp user/pass (without the @db)?

  Maybe that's part of it (where my question on ORACLE_SID).

  Be aware that the "directory" is an object of directory oracle rather than a directory on the file system - so something like

  SQL > create directory as ' / tmp';

  expdp directory = test

  See you soon,.
