Error - Java SDK already installed, but it's not.

877909Jul 25 2011
I am running WinXP SP3. I have the latest JRE installed ( 1.6.0_26-b03 ).

I downloaded the SDK with netbeans bundle.
It appeared to install correctly ( I wasn't really watching it ).
Netbeans runs, but complains it can't find the JDK.

Sure enough, there is no JDK folder under C:\Program Files\Java\ ( or anywhere else on my computer ).
I checked Add/Remove programs from control panel. Not listed there either.

So I tried to re-install, and it says netbeans is already installed, would you like to instal the JDK ?
I say yes, and it complains that it is already installed.

I really have no idea what's going on here.
I really don't care if it's installed already ( even though it's not ).
The installer should just re-install it.

Is there a way to force the installer to just install it ?

Hi Wolfgang,

Are you looking to load data into 10g or 11g?

If you are looking at 11g, sample files are located at $ORACLE_HOME/md/demo/network/rdf_demos/ (as specified in the documentation). This location contains a ctl file and a sample sql file that uses that ctl file. You could modify the sample sql file (bulkload.sql) to load multiple files (please refer to the SQL*Loader documentation for more details).

Detailed instructions on the load process are in section 1.7 of the 11g Oracle Database Semantic Technologies documentation. The Oracle Technology Network includes links to the 11g documentation.

Hi Melli,

Thanks for your answer. I am loading data into 11g.
I found the samples. I was also looking for an easy way for uploading all files within a directory, which I found out is not possible directly (i.e. it is not possible to specify a directory in the ctl file). So there are two possible solutions to this:
1.) Create a list of all files in the directory (on Windows with "dir/b *.nt > files.dat"), prefix every line with "INFILE", surround the filenames with a paragraph and include all that in the ctl file.
2.) It should also be possible to let a SQL-script create the list ("host dir/b *.nt > files.dat"), load this list into a temp-table and iteratively invoke the sqlldr.

For me solution 1 worked perfectly.

However when trying some sample queries (the LUBM test queries) I observed some very strange behaviour of SEM_MATCH (see thread "Missing triples in SEM_MATCH query")
