I have successfully installed Zope-2.0.1 (from the RPM) and ZOracleDA-2.1.0 over RedHat 6.0 for Intel x86. I am using Oracle 8.0.5.0.0 for Linux which runs SQLPlus, etc. just fine. The ZOracleDA install passes the DCOracle_test.py script when run from root and the dba account, so AFAIK everything s/b hunky dory and I have established (to myself at least) that I am not a complete moron. However, I am unable to set up a ZOracleDA connection and connect to Oracle. I can set up a connection object without connecting immediately, but subsequent connection attempts on this object fail. The browser (NC 4.6) gives me a "The document returned no data. Try again later or contact the server's administrator." message. Inspection of the /var/zope directory shows a sqlnet.log file which contains the following connection string: (DESCRIPTION=(ADDRESS=(PROTOCOL=beq)(PROGRAM=oracle)(ARGV0=oracle)(ARGS='(DE SCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))')(DETACH=NO))(CONNECT_DATA=(C ID=(PROGRAM=)(HOST=localhost.localdomain)(USER=nobody)))) This fails with a number of errors TNS-12206 TNS-12545 TNS-00515 The Linux distro of Oracle does not include error message docs :-( But a copy of the WinNT docs I have does not include TNS messages over c TNS-05000 but does mention TNS-00515. This is a "Target not found" message - meaning either the Oracle executable cannot be found or the node cannot be found.The documentation indicates the the ORACLE_SID must be included in the bequeath protocal connection string, and it is notably absent from the above. I have put all my Oracle environment variables (ORACLE_SID, ORACLE_HOME, etc., and a PATH entry to the Oracle /bin directory) in /etc/profile. However, I am using nobody as the Zope user ID, and I cannot remember whether a non-login account such as nobody will execute /etc/profile or not. If not, how is Zope going to find out where oracle is and what the SID is? Should I use another account or is there some other way to pass the environment variables to ZOracleDA? Or is there some other problem? I have looked at various pieces of code, but have done no work with Python before, and haven't done anything professionally with Unix or Oracle for over 12 months, and that was a a developer, not a DBA. Any ideas as to how to attack this problem will be gratefully received TIA Andrew Andrew Nerlich Strategic Operating Solutions Pty Ltd (02) 9966 8707 0418 407 833 ajn@sosos.com.au
