SHELL脚本放在crontab里执行报错

SunPeng040709

各位大侠帮忙看看，我有个脚本，内容如下：
$cat abc.sh
#!/bin/sh
if [ -f $HOME/file.info ]
then
        rm $HOME/file.info
        rm $HOME/newfile.info
fi
svrmgrl << EOF
connect system/manager
spool /usr/oracle/newfile.info
select name from v\$datafile;
select member from v\$logfile;
select name from v\$controlfile;
spool off
exit
EOF
cat $HOME/newfile.info|awk '/\//' >> $HOME/file.info
$ls -l abc.sh
-rwxr-xr-x   1 oracle   dba          454 Jan 17 07:50 abc.sh
直接在命令行执行abc.sh没有问题，能得到想要的结果，但是一放到crontab里执行，就出错
$cat newfile.info
select name from v$datafile
*
Error while trying to retrieve text for error ORA-03114
select member from v$logfile
*
Error while trying to retrieve text for error ORA-03114
select name from v$controlfile
*
Error while trying to retrieve text for error ORA-03114
$ls -l file.info
-rw-------   1 oracle   dba            0 Jan 17 07:55 file.info
file.info文件大小为0
是什么原因呀？
