Install Oracle 7.3 with SQL*NET 1 listener

Hi all,

It was an information how to install Oracle 7.3 Server with SQL*NET TCP/IP Server 1.0 some weeks ago. I tried to do this with Oracle 7.3.2 for OS/2 and two SQL*NET TCP/IP Servers 1.0 from Oracle 7.1.4 and Oracle 7.2.2 for OS/2. After setup I run tcpsrv and it works. But when I try to connect through SQL*NET 1.0, listener starts shadow process and terminates it one moment later. Client is waiting for connection forever.
Does anybody know how to solve this problem? Does there exist some hack with DLLs or configuration files?
