CTD 1.1.2 or 1.5.x and Oracle 8.1.5 ( Oracle 8i ) – Support Wiki

CTD and Oracle 8i
Description:
CTD Applications fail to connect to Oracle 8i (also called Oracle 8.1.5 or Oracle 8.1.6)
Solution:
There are actually two solutions to the problem.
You can install the Oracle NET8 client software from Oracle 8.0.5 and it will communicate correctly with Oracle 8i. You can also use the SQL*Net 2.3 client software from Oracle 7.
-OR-
Use the Oracle 8i (8.1.5 or 8.1.6) client software and manually add the following entry into the Registry at location:
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\
Add the following string value:
ORAOCI ORACLIENT8.DLL
and you will be able to successfully use the Oracle 8i (8.1.5 or 8.1.6) client software. You will still
need to run the VIEW8.ORA and PLSVIEW8.ORA scripts, logged on as “SYS", in order to use the
Database Explorer with Oracle 8i.
Note: This information only applies to Centura 32-bit applications, not to SQLWindows
16-bit applications, because the Oracle 8i client software is exclusively 32-bit.
