This is my problem. I am using the ACTIVESTATE perl version 5.26.1 fully updated. I have the oracle 8i client, 10g, and 12c clients all installed on my workstation. When I use DBI to connect to an 8i production database it is failing with an ORA-03134 error (version too old). The 10g client can connect to my 8i, 9i, and 10g database with no problems. I can't figure out how to generate the DBI module to use it with the 10g client. Any help would be appreciated
