com.lutris.appserver.server.sql.standard
Class StandardLogicalDatabase  

java.lang.Object
  com.lutris.appserver.server.sql.standard.StandardLogicalDatabase

All Implemented Interfaces:

com.lutris.appserver.server.sql.LogicalDatabase

---

public class StandardLogicalDatabase

extends java.lang.Object

implements com.lutris.appserver.server.sql.LogicalDatabase

Represents a logical database. Each logical database has a connection allocator and a object id allocator. The standard implementation of a local database is used when the database is described as of type Standard in DatabaseManager.DB.dbname.ClassType

The configuration data is specified in the section: DatabaseManager.DB.dbName

The following is a description of the sub fields:

• JdbcDriver - The JDBC driver to use to access that database. Manditory. E.g. "intersolv.jdbc.sequelink.SequeLinkDriver"
• Connection - This section is passed onto the connection allocator. See for details on connection allocator sub fields.
• ObjectId - This section is passed onto the object id allocator. See for details on object id allocator sub fields.

Since:

LBS1.8
