Spent an evening and few hours more learning how to install Oracle and DCOracle2 on linux to be used with Zope. Distribution that I am using is Fedora core 1. I Downloaded Oracle9i Enterprise Edition Release 9.2.0.1.0 and followed excellent instructions on page: http://www.tldp.org/HOWTO/Oracle-9i-RH8-and-RH9-HOWTO-1.html Following step by step the installation went just swimmingly. I downloaded DCOracle2 from zope.org: http://www.zope.org/Members/matt/dco2/ While doing make ( see INSTALL ) make sure that you have ORACLE_HOME and LD_LIBRARY_PATH set, and that you have sufficient rights to those shared libraries. Set those enviroment variables also to zope start-script, or otherwise your zope startup will fail when DCOracle tries to import those libs. Just an example I had to add these to my zope startup-script: ORACLE_BASE=/home/oracle/ ORACLE_HOME=/home/oracle/product/9.2.0.1.0 ORACLE_SID=portaali LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/network/lib export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH And now it works. -- -huima
