问题 I think I am almost there. I created an instance of AWS BeanStalk and added an oracle DB instance to it. When I found the log, I saw the driver was loaded but it keeps saying that URL is invalid. Here are my RDS info and log message. [RDS Info] Endpoint = aa1c9autjaqoufk.c2k1ch01futy.ap-northeast-2.rds.amazonaws.com Port = 1521 Public Access = yes [System Log] 25-Jun-2018 02:42:56.759 INFO [main] org.apache.coyote.AbstractProtocol.init Initializing ProtocolHandler ["http-nio-8080"] 25-Jun

问题 I found this in the Tomcat documentation here What I don't understand is why they close all the JDBC objects twice - once in the try{} block and once in the finally{} block.

When using a connection pool, closing the connection just returns it to the pool for reuse by another

问题 I want to update the application to App Store and off the ATS. Does Apple allow the application to off ATS and live to App Store? 回答1: Yes.

问题 I want to execute a custom command against a typed dataset I created using the dataset designer. For this I need to get a reference to the underlying connection, right? How to go about this? In which autogenerated file can I find the connection? 回答1: You can set the ConnectionModifier property of the TableAdapter in the designer, is defaulted to Internal, so you can use it in the same project/assembly, change it to Public and use it everywhere you need it. Or a better aproach will be create a

问题 I have an already source connection in SSIS "Connection Managers". It is a custom connection (not a oledb or any other standard connection types). Is it possible to reuse it (i.e call it) in the Biml script without writing the connetion string again? I saw two ways on the internet but neither worked with me: I did an example to connect to Advanturwork database, bellow are the screenshots of the project and the error message as well as the code of the two ways. Here is the porject files. This

问题 From the smartwatch I'd like to intercept the event of the connection to a smartphone. This is automatically managed by Android and Android Wear so I need to get this event from my app running on the watch. I found out this on WearableAPI to be notified without polling Wearable.NodeApi.getConnectedNodes public class MyService extends WearableListenerService { @Override public void onPeerConnected(Node peer) { Log.i("my wear service", "connected"); super.onPeerConnected(peer); // here I would
