If you're currently running 7.3.2.3, then you're also running SQL*Net 2.3, which will operate bidirectionally with Net8. The best approach is to run the Net8 Listener on the server which will support both SQL*Net and Net8 clients. sensenig@niehs.nih.gov wrote: > I have a DEC Alpha/2100 server running Digital UNIX 4.0b > running ORACLE 7.3.2.3.0. > > I want to install Oracle8 Version 8.0.3.0.0 while maintaining the > database instances using Oracle 7.3.2.3.0.
