Neo4j web admin

Is it possible to change the开发者_运维百科 database that I wish to query? The gremlin console only shows:

==> Available variables:
==>   g = neo4jgraph[EmbeddedGraphDatabase [/Users/Development/neo4j/neo4j-advanced-1.5.M01/data/graph.db]]

In the same directory I do have another db. I'm unable to change the configuration property:

store_dir

You can point to other instances but these are before the console is started. The changes are made to the:

../conf/neo4j-server.properties
