Server Utilities :: Multiple Export / Import Dump Files?
Apr 25, 2011
I am trying to export/import of a schema who's size is around 60 GB.
Export parfile goes like this..
file=expdmp1.dmp, expdmp2.dmp, expdmp3.dmp, expdmp4.dmp, expdmp5.dmp, expdmp6.dmp, expdmp7.dmp
filesize=10240M
log=explog.log
owner=owner1
Import parfile goes like this..
file=impdmp1.dmp, impdmp2.dmp, impdmp3.dmp, impdmp4.dmp, impdmp5.dmp, impdmp6.dmp, impdmp7.dmp
filesize=10240M
log=implog.log
fromuser=owner1
touser=owner2
ignore=y
I am going to run this on production. So want to check it..

I have 3 dump files: A.dmp, B.dmp, C.dmp . Can I use multiple REMAP_TABLESPACE entries in a par file to remap the table spaces for the above dump file?
Parfile would look something like this:
DIRECTORY=dpump
DUMPFILE=A.dmp,B.dmp,C.dmp
JOB_NAME=import_3_schemas
REMAP_TABLESPACE=A1:D1
REMAP_TABLESPACE=B1:E1
REMAP_TABLESPACE=C1:F1
The first remap entry is only relevant to A.dmp file
The second remap entry is only relevant to B.dmp file
etc.

exporting a big table (many rows = 3.000.000). Using the command exp the error message returned is "expdat.dmp > EXP-00028: failed to open expdat.dmp for write". Is there a possibility to export this table in multiple files (as a splitter)?

If I want to import 10g export dump file in to the 9i database, I am connecting to 10g database from 9i database using
exp user/password@10gdb ....
However is there any option like executing 9i catexp.dat on 10g database and do the export from 10g database itself to be imported into 9i?

I tried to import a dump in 11g that was taken in oracle 9i. The import started but it hangs after some time. Exactly say it check only the character set of the DB's then it hangs. let me know if there are any specific procedures to import a dump from 9i to 11g directly.

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.

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 It seems exp/imp is obsolete.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?
> sqlplus

Enter user-name: ^C^C
- 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)?

I'm rying to import schema's from a dump file that came from a different environment.
What I have is:
1. dump file
2. log file of the export
I'm trying to import the file(containing three schemas) with remap_schemas, and it fails, gives a lot of ORA-00959: tablespace 'string' does not exist.
Now, I've read in OTN:
[URL]
that what you need to do in that case is to use the REMAP_TABLESPACE option,to redirect the objects to a different tablespace.
I don't see a name of the tablespace I'm getting the error for in the export log.I don't know if I have more tablespaces I have to redirect with REMAP_TABLESPACE.
I don't want to perform this 3 times, have an error, by that find out what's the next tablespace needing redirection and only then starting over...
How can I know from the dump file and the log file,what is the tablespace names i need for the redirection to my names? Or its just that the tablespace giving me the error is the only one in the dump file?

When I do the import the of succeeding dump, I drop the existing schema "SQL> drop user username cascade;" and import dump by " impdp system .... ". I would like to import a dump to an existing instance but only data import and will leave the current packages and other metadata untouched and unchanged on the said existing instance.
1. Do i need to drop user before the import if my requirements are the above?
2. If i need to drop user, what should be script.
3. For the import itself, what parameter should i use?
4. What are the necessaries I need to consider before doing the import.

I'm taking export dump using expdp of some schema's of total size is 300GB. This is the par file:
DIRECTORY=expdp
FILESIZE=32212254720
DUMPFILE=expdp_schema01.dmp,expdp_schema02.dmp,expdp_schema03.dmp,expdp_schema04.dmp,expdp_schema05.dmp,expdp_schema06.dmp,expdp_sche ma07.dmp,expdp_schema08.dmp,expdp_schema09.dmp,expdp_schema10.dmp,expdp_schema11.dmp,expdp_schema12.dmp,expdp_schema13.d
[code]....
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.
