Server Utilities :: Taking Export Dump Using Expdp Of Some Schema's Of Total Size Is 300GB
Mar 30, 2007
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.

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 It seems exp/imp is obsolete.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?

- 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 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 would like to export specific tables(not entire schema) including metadata. I am using a parameter file for expdp.
Tables=emp,dept
Does this also include all metadata or should i also add the below Include in the parfile ?
INCLUDE =Indexes,Sequences,Procedures,Views

I have to servers 'A' and 'B', On Server there is a schema with the name "test" having a table "t1". I want to import this t1 table to server B.
Is it possible to export dump using expdp to remote host.
I found that there is an option for this like "network_link". for testing this, I created a dblink from Server "B" to "A" named "vxmldb".
When I am using the below command on Server B there I am getting the following error.
C:>expdp directory=data_pump_dir logfile=test.log network_link=vxmldb schemas=test dumpfile=test.dmp

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 have a process to export a schema using expdp and import using impdp. Everything creates successfully except for a trigger. The trigger gives and error that the table or view does not exist. The account that I use to import the schema is different than the schema user but is a highly privileged account. I notice that the schema in the create or replace trigger line of code is remapped (I am using remapping in the impdp syntax) and the rest of the syntax of the trigger (which is just a sequence trigger for a primary key column) does not have the schema. In order to fix the issue, I have my bash script log into oracle as the schema user after the import of the schema and execute the trigger code. why do I have to do this for trigger code but not for other objects like views that create just fine.

is it possible to remap the database schema during export?
Our developers have their databases stored within individual schemas and i want to provide a dumpfile that each developer is possible to easily import to his schema. But when i want to impdp the dumpfile i have to know the schema name within the dumpfile to do a remap to the individual developers schema -> so providing a specific schema name for within the dumpfile would be great.
At the moment i'm getting the ORA-39146, schema does not exist on importing the database..

1)Want to perform an Export from a Production Schema and Import the results into Test Schema. BUT, do not want to export ALL objects from Production (only a subset of tables). Is this possible?doco on how to do this? (rather than a complete Export and then a complete Import).
2)I have 2 test instances of Oracle on the same development server, UNIT and SIT. Am using Oracle SQL Developer tool.
While in the UNIT instance, is there a way to select data from the SIT instance? An example of syntax to use?
3) Can tables in the UNIT instance be compared to tables in the SIT instance, through any existing Oracle utilities
