Hi Ian,
Thanks for the simplicity!
Can you give us an insight in how the instant client is different from the (enormous) ‘real’ version? In other words, when to use it, and when not?
Thanks!

Hello Douwe,
With the full Oracle Client you will get the Oracle ‘thick’ Client and loads of binaries for administration like the Oracle Universal Installer, import and export tools, tnsping etc. including more data providers like ODBC, OLEDB and all kinds of .Net providers.
The Oracle ‘thick’ client includes drivers for fancy functionality like connection pooling, reacting to FAN messages when DataGuard or RAC nodes are shutting down etc.
If you only need ‘simple’ database access for tools like SQL Developer, the Oracle Instant Client is the only thing you need, download, copy, set PATH and GO!
Cheers,
Ian.

Sounds great Ian,
so you could probably use it in about 99% of the situations…
