found out that I don't need to call index.delete() all the time, instead BerkeleyDbDataSource.close() aka XaDataSource.close() should do what index.delete() does, namely closing all databases (related to this datasource) and their bdb environment; so I do just that.

And that logical.log.1 seems to be a part of XA Transactions and I must find a way to see that it's closed or something On Sat, Jul 30, 2011 at 10:15 PM, John cyuczieekc <[email protected]>wrote: > in TestBerkeley.java > So far I've found that, bdb environment(and relevant databases) is(are) > only closed when index.delete() is called > and that can only be called when the current transaction is finished (else > it will complain that some bdb databases are not opened on txn commit) > Applying all those changes, the following file is still in use (due to > cannot be deleted): > > E:\wrkspc\bdb-index-fork\target\var\neo4j-db\logical.log.1 > This seems to be part of neo4j, though I am not sure why would it still be > in use even after graphDb.shutdown() > Any ideas why that would be still in use?
