Import oracle multiple dump files - oracle

I have multiple dmp files exported from an Oracle database with datapump using the parallel=4 option.
I'm on a standard edition so I can't use the parallel option, can I import the dump files anyway on my oracle using the command:
impdp system#oracletest schemas=<schema_name> exclude=user:\"='usename'\" directory=<dir_path> dumpfile='file01.dmp,file02.dmp,file03.dmp,file04.dmp,file05.dmp,file06.dmp'
The parallel option used for the export, has to be used also for the import?
The database contains multiple schemas inside and I want to import just one for now.

Export & Import in SQL DEVELOPER without datapump

I want to export below things from SQL developer
1-Only schema (tables structure)
2-Only data in excel form
3-Schema with data
after exporting this i want to import the same to the another database
So what steps should i follow for export and import?
I can not use DATA PUMP as i don't have DBA privilege
As you use Oracle 11g, I'd suggest you to forget about SQL Developer and use the original EXP and IMP utilities. Doing so, you'd avoid DBA-related-problems as these utilities don't require access to the directory (an Oracle object which points to (usually database server's) filesystem directory, and - in order to be able to use it - you'd need to have read/write privileges on it).
So - if you don't already have these, install Oracle Client which contains EXP/IMP and use them.

how to import a .dmp file in oracle sql developer

How can i import a .dmp file in to sql developer. i had already created schema and i just need to insert data with these dump files. I tried imp and impdb commmands in sql command line but of no use.
You don't use SQL Developer to process data pump or legacy EXPORT dumps.
You CAN use SQL Developer to create a Data Pump job which will process your data pump export - this assumes the file is avail on a DB directory.
For a better answer, tell us exactly what kind of 'dmp' file you have.
If it's a Oracle Export dmp, the only way to import it is with the Import utility.

Import of data in Oracle using impdp fails because of missing dependencies

I need to export a subset of an Oracle table and import it in another Oracle instance. The export using expdp works pretty well but when I try to import the data in the other instance using impdp tool it fails because there are dependencies (foreign keys) missing. Is there any option to force expdp tool to export all required dependencies as well?
no.
You should makie sure your dump set is complete.
What you could try is to use impdp to generate the sql file, apply the generated sql to the other database to only create the table[s]. For this you might need to do some edit work on the generated sql until it fits your task.
Next use impdp with contents=data_only to import the rows in the pre-create table[s]

How to selectively export oracle to dump - minus some procedures or packages

We need to export an 11g database to get it into an 10g system. But we need to leave out a package, or at least some functions and procedures, that were accidentally implemented using 11g-only features.
Thankfully, the 10g is just a reporting database and we need only a few of the procedures that were implemented in 10g.
Any thoughts? I've seen some options for table-only exports, or selectively exporting certain tables. But we do need some of the procedures to come along.
I would recommend using expdp (data pump export) on the 11g database specifying the VERSION and INCLUDE parameters:
expdp dumpfile=10g.dmp directory=data_pump_dir version=10.2 INCLUDE=PROCEDURE:"LIKE '%XXX'"
This will produce a data pump export file that is compatible with the 10g version of data pump import and includes procedures ending in XXX.
Alternatively, you can use the EXCLUDE parameter instead of include to if you have just a few objects to exclude.
If you use INCLUDE, only those items you specify will be exported.
There are a lot of options for filtering objects using data pump export/import via the INCLUDE/EXCLUDE parameters.

exporting oracle database (creating a .sql file of data )

I have an Oracle database on one PC. I have to migrate it to my other PC. Both use separate oracle installations. Now how can I export it from my one PC and then import it into other PC?
What are the commands for exporting and then importing it?
I want structure as well as data to be exported and then imported. I am using Oracle db.
You can export the data from your source database and import it into your new one.
A good link demonstrating the usage of these commands can be found here
It boils down to something like the following for exporting a full database:
%> exp USERID=<username>/<password> FULL=Y FILE=dbExport.dmp
%> imp USERID=<username>/<password> FILE=dbExport.dmp FULL=Y
There are a multitude of options for both commands to tailor it to your needs. For example, you can restrict the import command to only import certain tables via the TABLES parameter or you can move database object between users with TOUSER, FROMUSER parameters. There are also options on whether to export or import constraints, indexes, etc. You can find all the valid parameters for both commands by executing either:
%> exp help=Y
%> imp help=Y
You don't say which version of the database you are using. This is important information, because new features get added to Oracle with every release. For instance, in 10g Oracle introduced a new utility, DataPump, which replaces the older IMP and EXP (those utilities are still included in the install, they are just deprecated).
One of the neat things about DataPump is that we can execute from inside the database as well as from an OS command line. I recently posted an example of using DataPump from PL/SQL in this SO thread. `Oracle provide comprehensive documentation.
edit
Neither old fashioned IMP/EXP nor DataPump generate an SQL file (*). If that is really what you want (as opposed to just porting the schema and data somehow) then things get a bit trickier. Oracle has a package DBMS_METADATA which we can use to generate DDL scripts, but that won't deal with the data. To generate actual INSERT statements, your best bet is to use an IDE; Quest's TOAD will do this as will Oracle's (free) SQL Developer tool. Both IDEs will also generate DDL scripts for us.
(*) A Datapump import can derive the DDL statements from a prior Datapump export file, using the SQLFILE= parameter. But that is just the structure not the data.
