推薦：由于文件組 ‘DEFAULT’ 中的磁盤(pán)空間不足，無(wú)法為數(shù)據(jù)庫(kù) ‘TEMPDB’ 分配新頁(yè)
今天接到一個(gè)朋友的問(wèn)題，sql server報(bào)由于文件組 DEFAULT 中的磁盤(pán)空間不足，無(wú)法為數(shù)據(jù)庫(kù) TEMPDB 分配新頁(yè)，按照錯(cuò)誤提示應(yīng)該是tempdb空間不足，讓其查看tempdb對(duì)應(yīng)數(shù)據(jù)庫(kù)文件大小為不到4g，查看其對(duì)應(yīng)文件為自增長(zhǎng)，硬盤(pán)空間還有40g多點(diǎn)，那應(yīng)該沒(méi)有問(wèn)題。后來(lái)她說(shuō)

 　　一.出現(xiàn)EXP-00091錯(cuò)誤

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

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

　　EXP-00091: Exporting questionable statistics.

　　當(dāng)環(huán)境變量和數(shù)據(jù)庫(kù)的不一致，在導(dǎo)出統(tǒng)計(jì)信息時(shí)候，會(huì)報(bào)EXP-00091錯(cuò)誤。

　　二.查看NLS相關(guān)參數(shù)

　　[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.解決方法

　　1.設(shè)置NLS_LANG為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

　　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
