    Prob & Sol of Exp/Imp Utility

    Note:--Real Prob. in My Testing Development Server:-

    When I was exporting of my Development database(Oracle 10g R2),then some errors are occurred.
    Srcipt is given as:--Script's name (

    exp userid=<usernm>/<passwd> file=exp_sixmnth.dmp buffer=10000000 compress=y tables='<tab1>','<tab2>',....'<tabn>'
    query=\"where sb_dt\>to_date\(\'01-may-2011\',\'dd-mon-yyyy\'\)\" rows='Y' log=exp_sixmnth.log


    Export: Release - Production on Fri Jan 20 10:05:30 2012

    Copyright (c) 1982, 2007, Oracle. All rights reserved.

    Connected to: Oracle Database 10g Enterprise Edition Release - 64bitn
    With the Partitioning, OLAP, Data Mining and Real Application Testing options

    Export done in US7ASCII character set and AL16UTF16 NCHAR character set
    server uses WE8ISO8859P1 character set (possible charset conversion)

    About to export specified tables via Conventional Path ...
    EXP-00008: ORACLE error 1406 encountered
    ORA-01406: fetched column value was truncated
    EXP-00000: Export terminated unsuccessfully

    Solution of the Problem:--(You can choose any solution)
    Solution 01:
    Change the Database character set to AL32UTF8 will solve this problem.

    Solution 02:
    Apply Patch for BUG 6804150 if available for your platform.

    Solution 03:
    Install the Oracle patchset.

    Solution 04:
    Use 11g exp client utility.

    Common Problems:--

    ORA-01555: Snapshot too old

    Sol:--STOP working while you are exporting or use parameter CONSISTENT=NO. It means that the parameter consistent=Y is replaced by consistent=N.

    ORA-01562: Failed to extend rollback segment,

    Sol:- Create bigger rollback segments or set parameter COMMIT=Y , with an appropriate BUFFER parameter while importing.

    IMP-00015: Statement failed ........object already exists.

    Sol:-- Use the IGNORE=Y import parameter to ignore these errors.
