Dave Syer commented on DERBY-646:
---------------------------------
I would like to test this storage strategy, but I don't know how to set it up.
I have compiled the code against 10.2.1.6, and now I want to obtain a
connection (ideally through a DataSource). This is what I tried
System.setProperty("derby.subSubProtocol.memory",
"org.apache.derby.impl.io.MemoryStorageFactory");
EmbeddedDataSource ds = new EmbeddedDataSource();
ds.setDatabaseName("memory:test");
ds.setCreateDatabase("create");
Connection connection = ds.getConnection();
It fails with
java.sql.SQLException: Failed to start database 'memory:test', see the next
exception for details.
at
org.apache.derby.impl.jdbc.SQLExceptionFactory.getSQLException(Unknown Source)
at org.apache.derby.impl.jdbc.Util.newEmbedSQLException(Unknown Source)
...
There is no "next exception" in the stack trace.
I also tried:
System.setProperty("derby.subSubProtocol.memory",
"org.apache.derby.impl.io.MemoryStorageFactory");
DriverManager.registerDriver(new org.apache.derby.jdbc.EmbeddedDriver());
Connection connection = DriverManager.getConnection("jdbc:derby:memory:test")
which fails the same way.
