Hi Michael,
Thanks for the response. I have added the exact fail case scenario with
codes and configuration as follows,
We are using single threaded only.
I am using Neo4j 1.9.8 Embedded Database. The steps used to create node are
as follows,
1. Start the Transaction
2. Create the Node.
3. Set few properties to the node
4. Create two relationships with other nodes
5. Commit the transaction
6. Print the Node Id (eg. 13456)
7. Fetch the particular Node with the Node Id above with following query.
START root=node(13456) RETURN root;But the following error throws
EntityNotFoundException: Node 13456 not found
When I try to do the above transaction again, the program hangs at point no
4.
The Java Class used to create node with property and relation ship are as
follows,
Transaction trx = DataSource.getGraphDBAPI().beginTx();
try{
Node ndeTest= DataSource.getGraphDB().createNode();
ndeTest.setId("1");
ndeTest.setName("Test API");
ndeTest.setURL("www.test.com");
Node parentNode = neoUtil.findParentNode("Test");
parentNode.createRelationshipTo(ndeTest,
KnoxxiRelationshipType.API);
ndeTest.setStatus("1");
trx.success();
}catch (Exception e) {
trx.failure();
log.error("Test Node Creation Failed," + e.getLocalizedMessage);
} finally {trx.finish();}
log.info("Node Id : "+ ndeTest.getId());
The neo4j Configuration are as follows:
node_auto_indexing=true
cache_type=gcr
nodestore_propertystore_mapped_memory_size=150M
nodestore_mapped_memory_size=100M
relationshipstore_mapped_memory_size=500M
strings_mapped_memory_size=150M
relationship_auto_indexing=true
The last few lines on neo4j message.log file are as follows:
2015-03-20 09:25:08.030+0000 INFO [o.n.k.EmbeddedGraphDatabase]: GC
Monitor: Application threads blocked for an additional 385ms [total block

2015-03-20 09:25:25.766+0000 INFO [o.n.k.EmbeddedGraphDatabase]: GC
Monitor: Application threads blocked for an additional 395ms [total block
time: 5.76s]
Please guide me if i miss something out.
Best Regards,
