DBI and DBD::Oracle 1.19 should be compatiable with any version of Oracle

connect to an older database.


Within limits.

A 10g client for instance cannot connect to a database with a version <
8.1.7.4,
or an ORA-3134 will be encountered.

Older clients can often connect to the latest server, but it may not be
supported.
eg. if it doesn't work right, too bad.

Connections between Oracle 7 and 9.2 are not supported. A 9.2 client cannot
connect to a 7.3 database, though a 7.3 client can connect to a 9.2database.

We have an app that does this, simply because there is no way around it,
unsupported or not.
