oracle http server 启动不了

qtal110

ORACLE装好后，用sqlplus "/as sysdba"   startup 提示数据库打开
lsnrctl   start 提示成功，
可cd $ORACLE_HOME/Apache/Apache/bin
./startJServ.sh
/opt/oracle/product/9.2/Apache/Apache/bin/httpd:
error while loading shared libraries:libdb.so.2:cannot open shared object file:NO such file or directory /opt/oracle/product/9.2/Apache/Apache/bin/apachectl/start:httpd could not be started

我的APACHE是在ORACLE装好后再装的,放在/USR/LOCAL/APACHE中,WEB正常了,可ORACLE的HTTP怎么不行呢,错在哪?
