imp partition table in different schema

Query I used in par file



file='/oracle/export/tab/tab3a.dmp'
log='/oracle/export/tab/tab3a.log'
tables=esam.summary
query="where TID IN ('010003050000','010003080000','010003090000') AND SUMMARY_PERIOD BETWEEN '01-oct-2010' AND '31-dec-2010'"


exp “'/ as sysdba'" file='/oracle/export/tab/tab3a.dmp' log='/oracle/export/tab/tab3a.log'

Export log

Import into different schema on different server

 . importing ESAM's objects into NMAPP
Import terminated successfully with warnings.

Cause: Import utility verifies the syntax of all SQL statements in the dump file. Import utility uses default buffer size is 64k, if the SQL statement in the dump file exceeds the default buffer size, then import will be failed and raise 31 & 8 error..



Solution: increase the buffer size

imp "'/ as sysdba'" file='/oracle/export/tab/tab3a.dmp' log='/oracle/export/tab/tab3a.log' from user='esam' touser='nmapp' ignore=y commit=y buffer=100000


Import log

ORA-00959: tablespace 'SAM_SUMM_DBF' does not exist
Import terminated successfully with warnings.

My partition table having 50 partitions in prod and each partition in different tablespace but those tablespace doesn’t exist in QA.


Solution: Here we have 2 options to done this job.

1. Create missing tablespace in target, and then run import with buffer size.


2. Reff metalink document (ID: 372992.1) to import partition tables in different tablespace


                     a. Run the import utility with show=y or indexes=filename.sql
                     b. Save the ddl to a script file
                     c. Run the script in target db..

imp "'/ as sysdba'" file='/oracle/export/tab/tab3a.dmp' log='/oracle/export/tab/tab3a.log' from user='esam' touser='nmapp' ignore=y commit=y buffer=100000



this time partition tablespace are imported successfull without any mistake..
:-) feel happy now
