I am sorry if this is covered somewhere that I have been unable to find it. I have not been able to connect to the FAQ at http://dev.isystek.com/dbi/fom.cgi. The only faq's I have found on-line are dated CY2000, and do not appear to address this issue.
I am a UNIX admin, supporting a large Solaris Environment. I need to compile a set of DBI/DBD::Oracle modules such that they are able to access several different versions of Oracle databases, not all of which might exist locally on each machine. I originally assumed that compiling DBD::Oracle under the 'highest revision' oracle environment would be backward compatible, but the README.client seems to suggest that the ORACLE_HOME of the perl program's environment should be the same as what was used at DBD::Oracle Compile time. This tends to suggest that I need a different DBD::Oracle for each Oracle Revision, however there does not seem to be a mechanism within DBI to specify *which* DBD::Oracle driver to use. A previous email in this list said there was a connectivity matrix, but did not give a reference to where that exists. (ref: http://www.mail-archive.com/dbi-users@perl.org/msg23511.html) This tends to suggest that I might find one version that is 'most likely' to work across different versions. Or am I completely wrong-headed, and setting ORACLE_HOME and LD_LIBRARY_PATH allow the correct Oracle libraries to be found irrespective of the environment in which DBD::Oracle was compiled?) I am looking for the proper solution, not one that I might get to work now, but must re-architect for the next Oracle version installed. What is the way that DBI/DBD::Oracle should be configured when multiple Oracle versions are involved? To further complicate things, I am working under the restriction that I may not have a C compiler in my production environments, so the solution needs to be able to be built in development, then promoted to a c-less production environment. The Versions I am using: Perl 5.8.0 DBI DBI-1.48 DBD::Oracle DBD-Oracle-1.16 Oracle 8.1.7.[3,4] 9.2.0.[3,4,6] 10.1.0.2 (etc) GCC 2.95.3 20010315 Thanks for your attention jk
