问题 I have my java application deployed in websphere application server. I am successfully able to connect to neo4j from my java application using jdbc driver. But there are some performance issues with the approach i have followed. Currently neo4j server is running on Xms - 8G and Xmx-16GB. I have less amount of data that is aprox 40mb with 3100 nodes. When we test the performance over http with cypher, the performance is outstanding. But in the java application we are using the jdbc driver to

问题 I create a winform application that contains 3 textbox ( pcno , pcname and pcipadd ), one listbox that is using a datasource and one button to add new item.

In details, I currently have a "PCN01" on my

问题 Does anyone have a working example of using the new GWT constructs for RequestFactory with a SmartGWT DataSource for databound widgets ? If possible I would like to make a generic data service that contains methods for listAll , getByExample , getByPrimaryKey etc. I beleibe it should be possible ??? If using RequestFactory would it make sense to ditch the datasource altogether and work directly with the widget fields ? Cheers, Andy 回答1: http://forums.smartclient.com/showthread.php?t=10850

问题 I have a web application running on tomcat7. The tomcat7 and a global datasource configuration component are part of a jetty portal. Now, I can setup global datasources on the portal which get added to the context.xml (of my application on tomcat) as a ResourceLink. I want to know if there is a way to connect to these datasources through my application jdbc code without putting in a resource-ref in my web.xml. (This will help me connect to new datasource name without redeploying my WAR file

问题 My goal is to benchmark the latency and the throughput of Apache Beam on a streaming data use-case with different window queries. I want to create my own data with an on-the-fly data generator to control the data generation rate manually and consume this data directly from a pipeline without a pub/sub mechanism, i.e. I don't want to read the data from a broker, etc. to avoid bottlenecks. Is there a way of doing something similar to what I want to achieve? or is there any source code for such

问题 So essentially I'm trying to get my project up and running on AppFog. The datasource information is stored in an enviornment variable, which is essentially JSON. My goal is to take this data and set my datasource config from it. Here is what I have tried: Code to set the datasource config which is a method in a POGO. The POGO is instantiated and the method called at the beginning of DataSource.groovy: import appfog.ParseDataSource new ParseDataSource().setConfig() dataSource { ... } class

问题 Every environment you define in DataSource.groovy extends the base dataSource definition at the root of the file, outside of environments. I have two specific configurations that I need to apply to a number of different environments which have minor environment-specific changes. Really, I need two "base definitions", or some way to extend existing definitions. How do I do what I'm trying to do? dataSource1 { dbCreate = "update" dialect = org.hibernate.dialect.Oracle10gDialect pooled = false
