I'm searching for an old Oracle 126.96.36.199.1 the appropriate JDBC driver for Java 1.6.
It's not clear what your question is or problem is.
1. Are you looking for a JDBC driver that can connect to Oracle 188.8.131.52.1? Then you can use any JDBC jar file that is JDBC 10.2.0 or earlier as the doc you provided indicates. That link is the official Oracle page for JDBC support and has a link to the jar download page.
2. Are you looking for a JDBC driver that supports ALL of the Java 1.6 JDBC funcitonality? Then, again, as the doc shows you must use the 11.1.0 or later JDBC driver. Those drivers do NOT support connecting to your 184.108.40.206.1 database.
If you are looking for a JDBC driver that does both #1 and #2 then there is none; at least Oracle doesn't provide one.
So the JDBC jars you can use depend more on what level of JDBC functionality you intend to use.
I can use the CLASSES12.JAR file and JDK 1.6 and connect to and query my Oracle 220.127.116.11.0 database but that jar file won't support the latest JDBC enhancements available in the later jar files.
So as Tolls suggested you should generally use the LATEST jar file possible which, in your case, would be the OJDBC5.JAR file. That will connect to Oracle 8.1.7 and provides (from your doc)
Oracle 10.2.0 supports:
Full support for JDBC 3.0
Note that there is no real change in the support for the following in the database. All that has changed is that some methods that previously threw SQLException now do something more reasonable instead.
