The createrdfstore command creates an
empty RDF store without any data.
To create an optimized RDF store that is uses existing data,
use the createrdfstoreandloader command instead.

Command parameters
- -storename storeName
- Specifies a name for the RDF store. Ensure that the name satisfies
the rules for DB2® database table
names.
- -objectnames objNames
- Specifies a Java™ properties
file that lists the names of the RDF store tables. This file can be
any valid file name, but it must have the extension ".properties".
If
you do not specify the objectNames parameter,
system generated table names are used instead.
- -host hostNames
- Specifies the host where the database is located.
- -port portNumber
- Specifies the port number of the database.
- -db dbName
- Specifies the database to which a connection is established. The
minimum database page size is 32 KB.
- -user userName
- Specifies the authorization name that is used to establish the
connection.
- -password password
- Specifies the password that is used to establish the connection.
- -schema schemaName
- Specifies the database schema in which to create the RDF store.
- -predicatemappings predicateMappingsFileName
- In DB2 Version 10.1 Fix
Pack 2 and later fix packs, specifies the path of the file that contains
the predicate mappings that are to be used in the store. The mappings
occur between the predicates and their assigned columns. The mappings
are computed based on predicate occurrence.
- -systempredicates systemPredicatesFileName
- In DB2 Version 10.1 Fix
Pack 2 and later fix packs, specifies the properties file that contains
the filter predicates that are to be applied to the query. These system
predicates are stored in an RDF store to help enable graph level access
control.
Example
Example 1: The following command
creates a store named rdfStore1 in database DB1 with port 60000 and
schema db2admin on host localhost:
createrdfstore rdfStore1 -host localhost -port 60000 -db DB1
-user db2admin -password XXX -schema db2admin
Example 2: The following command creates a
store named rdfstore2 in database DB1 with port 60000 and schema db2admin
by using system predicates from the syspreds.props file and predicate
mappings from the
predicatemappings.nq file.
createrdfstore rdfStore1 -host localhost -port 60000 -db DB1
-user db2admin -password XXX -schema db2admin
-predicatemappings predicatemappings.nq -systempredicates syspreds.props
Usage notes
You must issue command and parameter
names in lowercase.
