Not able to import in oracle 11.1.7

That is a pretty generic error.  From what I could find it appears to be a version mismatch.  Are production and test on the same version?

There are a couple of Metalink notes in this thread that might be related:

Check if any of the components are invalid in the database

Check if any of the specific objects are invalid

Did you recently did a database flashback?

Hi Experts
As per you suggestions..

1.
Yes.. both Production and Test database run on same Oracle 11.1.7 version.

No... I did not do any database flashback recently.

When you transferred the dmp file did you make sure it was a binary transfer?

Yes it was. It was FTP ed from production server to the test server. The way we all usually do.

I have to ask mainly because I have done it, was the FTP in binary mode?

Can you FTP it again?

Maybe redo the export?

Some indicate that if any components are invalid (like you have) the datapump fails with this error.
Attempt to resolve the outstanding invalid components in your database.

Others indicate that this fixes the problem:
  connect / as sysdba
  startup restrict
  alter system set cluster_database = false scope=spfile;
  shutdown immediate
  startup upgrade
  alter system set cluster_database = true scope=spfile;
  shutdown immediate
  startup

Does the Stream_Pool_Size has something to do with it ?
My database is not configured with stream pool size..and when I tried doing one export from this database it gave the same error as I got while importing into it.
But when tried with other database where stream pool size was allocated it successfully exported..but I did not test the import onto it.

Any comments/views/suggestion..

Thanks

Definitely this could be your problem:

From 11G Utilities Manual
Setting the Size Of the Buffer Cache In a Streams Environment

Oracle Data Pump uses Streams functionality to communicate between processes. If the SGA_TARGET initialization parameter is set, then the STREAMS_POOL_SIZE initialization parameter is automatically set to a reasonable value.

If the SGA_TARGET initialization parameter is not set and the STREAMS_POOL_SIZE initialization parameter is not defined, then the size of the streams pool automatically defaults to 10% of the size of the shared pool.

When the streams pool is created, the required SGA memory is taken from memory allocated to the buffer cache, reducing the size of the cache to less than what was specified by the DB_CACHE_SIZE initialization parameter. This means that if the buffer cache was configured with only the minimal required SGA, then Data Pump operations may not work properly. A minimum size of 10M is recommended for STREAMS_POOL_SIZE in order to ensure successful Data Pump operations.

when the import was initiated the following error could be seen in the alert log

Errors in file /usr/app/oracle/diagl/diag/rdbms/iohdssl/IOHDSSL1/trace/IOHDSSL1_ora_1938.trc  (incident=100189):
ORA-04031: unable to allocate 56 bytes of shared memory ("streams pool","unknown object","streams pool","fixed allocation callback")

Since the datapump uses streams, it seems the inadequate streams/shared pool size is causing this issue.



This is what is the current status..

NAME                                 TYPE                             VALUE
------------------------------------ -------------------------------- ------------------------------
shared_pool_reserved_size            big integer                      25M
shared_pool_size                     big integer                      500M
streams_pool_size                    big integer                      0

500M isn't a lot for shared_pool.

What are your other memory parameters set to?

I would strongly suggest automatic memory management:
http://download.oracle.com/docs/cd/E11882_01/server.112/e16638/memory.htm#PFGRF94254

then if Oracle needs more for specific tasks, it can borrow from other areas.
