[edit] Oracle 7.0 - June 1992

[edit] Upgrading SQL*Net v1 to v2

SQL*Net v2 (introduced with 7.0) cannot talk with SQL*Net v1, and vice versa. The only way to overcome this problem is to run SQL*Net v1 and v2 simultaneously on the same database server. You can then install SQL*Net v2 on your clients as time permits. SQL*Net v1 and v2 can coexist on the same server, or on the same client.

You can also list v1 connect strings in your TNSNAMES.ORA file. Eg: ORA1_NET1 = T:machine_name/port:database_name

Note that SQL*Net v1 was not shipped with version 7.3 of the database.
