Server Utilities :: Export / Dump With Expdp For Non-privileged Users?
May 29, 2012
We are DB users (not DBAs) and used always exp/imp bevore application upgrade.
Was googling arround and read something like "Oracle Data Pump - Time to let go of Exp / Imp". It seems exp/imp is obsolete.
Our system doesn't have "expdp" command
> find . -name expdp
>
is this because of too old SQL*Plus?

SQL*Plus: Release 8.1.7.0.0 - Production on Tue May 29 16:05:28 2012

- does our DBA need to give us privileges to run expdp/impdp?
- is that true that a expdp/impdp dump will be on the Oracle server (not the client machine)?
here one biggest schema size is 250GB and the total size of all the schema's is 300GB. The file where am taking the dump has 350GB space but even then the expdp failed saying
ORA-39095: Dump file space has been exhausted: Unable to allocate 8192 bytes
why it failed and how to restart it and make sure it runs successfully without error.

We have two databases running on 10.2.0.4 and 9.2.0.8. Both are having the same unpartitioned table of size 80G. I am exporting the table on 10g by using parallel=8 and dumpfile with %U option. That took around 4 hours to export the table.
And on 9.2.0.8, i am exporting using below parameters, taking around 5 hours.
buffer=2000000 recordlength=64000
options i can try to speed up the export in both versions.
I want to take a schema level export .The schema size is 115 GB size . Do we require same amount of space to be available in server side (where we are taking a dump) as the schema size or less or more space is required in server side ?

I am trying to export Schema using expdp command. but its going hang after few minutes. it seems that it stucks any where. Even I am trying with normal scott schema it is also hanging.
I export a table using exp utility it take 30 mins to complete the export.The same i have done in expdp utility it take 10 mins to complete the export.
But gives the following error ORA-31693: Table data object "LOG"."DAILY_LOG" failed to load/unload and is being skipped due to error: ORA-00904: "YYYYMMDD": invalid identifier
I tried with simple sql with YYYMMDD and it works fine, the entry_date is a char field. in QUERY where i'm doing wrong here?
I have a server configured to German & English. when i connect with SQLPLUS, i have German language server output, but when i do "alter session set nls_language='AMERICAN'" - it solves the issue for me.
I need the same for expdp command, but I don't know how to do this. I have tried to add a parameter nls_language, but expdp doesn't recognize it. Is it possible to somehow see server output of the expdp & writing it to the log file in English?

I want to take an export of table MESSAGE, and filter it for the day of 17 JUL 2013 (just to limit the size). i used the following expdp command but its not working.

But with select query i am able to retrieve the rows for the specific date.

From some day I have this error during export data pump:
Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options ORA-31626: job does not exist ORA-31687: error creating worker process with worker id 1 ORA-31687: error creating worker process with worker id 1 ORA-31688: Worker process failed during startup.
This error is random, if I retry after few minutes the expdp work correctly.
So, I want to export two schemas from database with condition:
1. I want to export scheme_1 with all metadata objects + data. 2. I want to export scheme_2 with only metadata objects.
Oracle version is Oracle EE 10.2.0.4.0, OS - Microsoft Server 2003R2.
As far as I know I can not use parameter EXCLUDE like:
EXCLUDE =TABLES:" IN ('SCHEMA_NAME.TABLE')"
(-but this parameter will give me no tables at all) or I can not use CONTENT=SCHEMA_NAME.METADATA_ONLY, maybe I can use QUERY=where table in (select tablename where schema is .... - but I have tables with same name in both schemas).
