All Implemented Interfaces:

FileSystem

public class DB2FileSystem

extends DbFileSystem

DB2FileSystem is a JDBC-based FileSystem implementation for Jackrabbit that persists file system entries in a DB2 database.

It is configured through the following properties:

• driver: the FQN name of the JDBC driver class (default: "com.ibm.db2.jcc.DB2Driver")
• schema: type of schema to be used (default: "db2")
• url: the database url (e.g. "jdbc:db2:[database]")
• user: the database user
• password: the user's password
• schemaObjectPrefix: prefix to be prepended to schema objects

See also DbFileSystem.

The following is a fragment from a sample configuration:

   <FileSystem class="org.apache.jackrabbit.core.fs.db.DB2FileSystem">
       <param name="url" value="jdbc:db2:test"/>
       <param name="schemaObjectPrefix" value="rep_"/>
   </FileSystem>
