isql無法登陸數(shù)據(jù)庫

inhance

我在服務器上用isql無法登陸數(shù)據(jù)庫
$ isql -Usa -P -Swgsybase
The context allocation routine failed when it tried to load localization files!!
One or more following problems may caused the failure

Your sybase home directory is /u/sybase. Check the environment variable SYBASE i
f it is not the one you want!
Using locale name "C" defined in environment variable LANG
An error occurred when attempting to allocate localization-related structures.
我估計是服務器配置文件的問題，因為我用其他機客戶端都可以正常連接數(shù)據(jù)庫。服務器的環(huán)境變量是這樣的：
$ set
HOME=/u/sybase
HZ=100
IFS=

LANG=C
LD_LIBRARY_PATH=/usr/sybase/ASE-12_5/lib:/usr/sybase/OCS-12_5/lib:/usr/lib:/usr/
sybase/SQLRemote/lib:
LOGNAME=sybase
MAIL=/var/mail/sybase
MAILCHECK=600
OPTIND=1
PATH=/u/sybase/ASE-12_5/bin:/u/sybase/ASE-12_5/install:/usr/bin:/usr/sbin:/u/syb
ase/OCS-12_5/bin
PS1=$
PS2=>
SHELL=/bin/sh
SYBASE=/u/sybase
SYBASE_ASE=ASE-12_5
SYBASE_EJB=EJB-12_5
SYBASE_FTS=EFTS-12_5
SYBASE_OCS=OCS-12_5
SYBASE_SYSAM=SYSAM-1_0
TERM=ansi
TZ=PRC
請問應該怎樣修改呢？
