So I have two threads that works with Database.
Both threads have opened database in OrientGraphFactory (database is opened
once at program start in both threads)
new OrientGraphFactory(host, user, password).setupPool(1, 10);
In first thread I create clusters by code like this
OrientGraph graph = factory.getTx();
try {
project.vertexTransaction(graph);
//Vertices clusters
new OCommandSQL(
"ALTER CLASS Resource ADDCLUSTER " +
DatabaseClasses.RESOURCE.getName() + project.getCluster()
).execute();
//... more code like this
} finally {
graph.shutdown();
}
The second thread is actually a Java Service and executes its code
seconds/minutes/hours later after this command is finished I pass cluster
names to this thread so it knows which clusters it should use.
