Experts,
I am using expdp/impdp to migrate 4 TB database from solaris
to Linux.But the import process is taking forever.
Can you please tell me any other methods for migrating.
Thanks,
Varun

Perhaps you could tune the export/import process a bit. Some suggestions:
Set all the check constraints to ENABLE NOVALIDATE before you export.
Set all indexes to NOLOGGING before you export.
Set all the destination tablespaces to NOLOGGING before you import.
Set your PGA_AGGREGATE_TARGET to many GB more than usual.
Set DB_BLOCK_CHECKING/CHECKSUM=false
Set "_smm_max_size"=4000000
Set "_pga_max_size"=4000000000
Use lots of Data Pump worker processes
Don't use network mode
Just a few ideas - please don't blame me if they don't work. If they do, or if you have any other ideas, I would like to know. I have a problem at the moment with a Data Pump exp/imp that is taking too long.

Hi ,
I am also facing the same issue of hanging impdp operation at the place of "Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX". The dumpfile contains only metadata only.
Import> status
Job: IMPFULLVERSION
Operation: IMPORT
Mode: SCHEMA
State: EXECUTING
Bytes Processed: 0
Current Parallelism: 1
Job Error Count: 0
Dump File: E:\tools\oracle10g_EE\oracle\product\10.2.0\db_1\admin\orcl\dpdump\expdp_fullNov16.dmp
Worker 1 Status:
State: EXECUTING
Object Schema: VERSION
Object Name: ABC_P
Object Type: SCHEMA_EXPORT/TABLE/INDEX/INDEX
Completed Objects: 93
Worker Parallelism: 1
if I exclude the above object during impdp , then the process will hang on some other object. Please suggest a solution.

Hi,
The hanging at the place of index of impdp process is solved by adding tablespace . Actually I am importing only metadata and enough space was also there in the tablespace alloted , again it shows the error 'ORA-01659: unable to allocate MINEXTENTS beyond string in tablespace string '. Now the impdp statement got end with the below error :
Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX
Processing object type SCHEMA_EXPORT/TABLE/CONSTRAINT/CONSTRAINT
Processing object type SCHEMA_EXPORT/TABLE/CONSTRAINT/REF_CONSTRAINT
Processing object type SCHEMA_EXPORT/TABLE/POST_TABLE_ACTION
Processing object type SCHEMA_EXPORT/TABLE/MATERIALIZED_VIEW_LOG
ORA-39014: One or more workers have prematurely exited.
ORA-39029: worker 1 with process name "DW01" prematurely terminated
ORA-31672: Worker process DW01 died unexpectedly.
Job "SYSTEM"."SYS_IMPORT_SCHEMA_02" stopped due to fatal error at 10:05:53
in the alert_orcl.log , the error is
Errors in file e:\tools\oracle10g_ee\oracle\product\10.2.0\db_1\admin\orcl\bdump\orcl_dw01_5956.trc:
ORA-00600: internal error code, arguments: [kkzlcsl-1], [0], [], [], [], [], [], []

Okay thanks. Can anyone help to understand the other issue I faced? Even after having enough tablespace , It has given the error -'ORA-01659: unable to allocate MINEXTENTS beyond string in tablespace string '.
