loading a big file to a new DB

[Rui Li]

hi, 

I am new to stardog. It's an awesome product. But I am tumbling a little. 

I have put my ontology into an RDF owl file and tried to use the following command to load them to DB (with Stardog community version). 

stardog-admin.bat db create -n myDB RDF.owl. 

Then it complained that I have too many entities in the file. Error message is:

Errors were encountered during loading:

File: D:\_SHARED\WORKSPACE\TOOLS\WORK\stardog-3.1\bin\..\examples\data\RDF.owl Message: The parser has encountered more than "64,000" entity

expansions in this document; this is the limit imposed by the application. [line 1, column 1]

The documentation says that the community version supports up to 25M triples in one DB. My ontology has far less triples than that limit. I am wondering what's my alternative to load the whole ontology?

Thanks!

Rui

You might find this previous post [1] on the list helpful.

Thanks! This is exactly the same problem I have. The solution looks straight forward too. But I can't find either jdk.xml or jaxp.properties in my java lib folder (C:\Program Files\Java\jdk1.6.0_26). 

Rui.

You could try the JVM argument as the post I reference suggests.

Got it. I modified stardog-admin.bat and it works! Thanks a lot, Mike! (I am on Windows)

if "%STARDOG_JAVA_ARGS%"=="" set STARDOG_JAVA_ARGS=-Xmx2g -Xms2g -XX:MaxDirectMemorySize=1g -Dfile.encoding=UTF-8 -DentityExpansionLimit=1000000
