    [EXP-00091:,Exporting,questionable,statistics] statistics已停止工作

    时间:2020-05-27来源:山茶花美文网 本文已影响 山茶花美文网手机站

    一.出现EXP-00091错误

    [oracle@localhost tmp]$ exp ""/ as sysdba"" tables=testxuchao.TAB_XN_PY_DICT

    > file=/tmp/xifenfei.dmp log=/tmp/xifenfei.log

    Export: Release 9.2.0.4.0 - Production on Mon Jan 16 16:02:37 2012

    Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

    Connected to: Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production

    With the Partitioning, OLAP and Oracle Data Mining options

    JServer Release 9.2.0.4.0 - Production

    Export done in US7ASCII character set and AL16UTF16 NCHAR character set

    server uses ZHS16GBK character set (possible charset conversion)

    About to export specified tables via Conventional Path ...

    Current user changed to TESTXUCHAO

    . . exporting table TAB_XN_PY_DICT 25433 rows exported

    EXP-00091: Exporting questionable statistics.

    EXP-00091: Exporting questionable statistics.

    Export terminated successfully with warnings.

    当环境变量和数据库的不一致,在导出统计信息时候,会报EXP-00091错误。

    二.查看NLS相关参数

    [oracle@localhost tmp]$ echo $NLS_LANG

    AMERICAN

    SQL> col value for a30

    SQL> select parameter,value from nls_database_parameters

    2 where parameter like "%CHARACTERSET%";

    PARAMETER VALUE

    ------------------------------ ------------------------------

    NLS_CHARACTERSET ZHS16GBK

    NLS_NCHAR_CHARACTERSET AL16UTF16

    三.解决方法

    1.设置NLS_LANG为NLS_CHARACTERSET

    [oracle@localhost tmp]export NLS_LANG=american_america.ZHS16GBK

    [oracle@localhost tmp]$ exp ""/ as sysdba"" tables=testxuchao.TAB_XN_PY_DICT

    > file=/tmp/xifenfei.dmp log=/tmp/xifenfei.log

    Export: Release 9.2.0.4.0 - Production on Mon Jan 16 16:08:10 2012

    Current user changed to TESTXUCHAO

    . . exporting table TAB_XN_PY_DICT 25433 rows exported

    Export terminated successfully without warnings.

    2.使用statistics=none

    [oracle@localhost tmp]$ exp ""/ as sysdba"" tables=testxuchao.TAB_XN_PY_DICT

    > file=/tmp/xifenfei.dmp log=/tmp/xifenfei.log statistics=none
