Orientdb connection not closing - orientdb

Question

I am using Orientdb 2.2.12.
This below is single source from where I am getting Connection instance
public static synchronized Connection getOrientDbConnection(String appName)
{
try {
// address of Db Server
OServerAdmin serverAdmin = new OServerAdmin
("remote:" + ip + ":" + port + "/"
+ appName).connect("root", "1234");
if (serverAdmin.existsDatabase())
{
serverAdmin.close();
Properties info = new Properties();
info.put("user", "root");
info.put("password", "1234");
Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:" + ip + ":" + port + "/"
+ appName, info);
//System.out.println(" Database Connection instance returned for : " + appName + " for thread ID : " + Thread.currentThread().getId());
return conn;
}
else
{
// "Type_Of_Db", "Type_Of_Storage"
serverAdmin.createDatabase("GRAPH", "plocal");
serverAdmin.close();
OrientGraphFactory graphFactory = new OrientGraphFactory(
"remote:" + ip + ":" + port + "/" + appName);
/**
* ####################### Do This only Ones-Per-Database #####################
* 1. Create index with unique field
* #name = unique index will be created only one time for a particular database
*
*
*/
OrientGraphNoTx graph = graphFactory.getNoTx();
graph.createKeyIndex("name", Vertex.class, new Parameter<String, String>("type", "UNIQUE"));
// shutdown the graph which created Index immediately
graph.commit();
graph.shutdown();
// close all db pools
graphFactory.close();
try
{
Properties info = new Properties();
info.put("user", "root");
info.put("password", "pcp");
Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:" +ip + ":" + port + "/" + appName, info);
//System.out.println(" Database created and Connection instance return for : " + appName + " for thread ID : " + Thread.currentThread().getId());
return conn;
} catch (Exception e) {
//System.out.println("Problem creating database or getting connection from database " + " for thread ID : " + Thread.currentThread().getId() + e.getMessage());
e.getMessage();
return null;
}
}
}
catch(Exception e)
{
e.getMessage();
}
return null;
}
My use-case is creating :-
vertexes
edges
update vertex, edges etc..
App.java
Connection conn = DB.getOrientDbConnection(String appName)
// create vertex
// create edges
conn.commit()
conn.close();
What problems I am facing ?
Even after program finishes and conn.close() done, JConsole showing Orientdb connection still active.

Is this a bug or I am doing something wrong?

Answer 1

If your server is running you will see that in JConsole.
