Question : Apache won't start

I have O9i installed on Linux 9. When I try to start Apache with
./apachectl start, I get the message:
syntax error line 228 of http.conf
cannot load /u01/app/oracle/Apache/Apache/libexec/mod_rewrite.so
 into server
/u01/app/oracle/Apache/Apache/libexec/mod_rewrite.so
undefined symbol: dbm-fetch
What do I need to do to get it running?

Answer : Apache won't start

as I said in my first comment: your mod_rewite.so is not compiled and linked against the installed libdb.so .
You need to compile and link it again.
