h2ormlite

h2 disconnect and connect

i got a problem when i'm closing an h2 connection(release database) and try to connect to another h2 database(debug database).

Snipplet to connect: 

this.connection = new JdbcConnectionSource(connectionString);

Snipplet to disconnect:

this.connection.close();

ConnectionString:

jdbc:h2:file:/data/data/my.app/databases/myapp
jdbc:h2:file:/data/data/my.app/testdatabases/myapp

Then instead of using the "new" connection the old one is used. I'm using different directories for the databases. In both cases when i try to toggle between database1 and database2 the .lock and .trace files are not deleted in their directories.

I want exclude implmentation failures on my side. I'm using h2(current version) with ormlite on android 4.2.2.

Solution

  • Then instead of using the "new" connection the old one is used.

    If you are creating a new ConnectionSource then you will need to re-create all of your DAO classes and clear the DAO cache from within the DaoManager. Each of the DAO classes has a copy of the old connection source that it uses.

    ConnectionSource connectionSource = new JdbcConnectionSource(connectionString);
DaoManager.clearCache();
Dao<Foo,Integer> fooDao = DaoManager.createDao(connectionSource, Foo.class);
