When I use tdengine, the link is not released after the timeout period, and eventually no link is available. The version of tdengine I use is 2.4.0.30, and my jdbc version is 2.0.38. The problem has not been located yet. What is the maximum time that tdengine's jdbc can configure？

Or is it possible that there's a problem with my code? We use java's webflux to develop.

As some of us have noted, parse.com will be shut down in January 2017. In the current version of parse4cn1, all requests go to https://api.parse.com, using the constant ParseConstants.API_ENDPOINT. Will it be possible to supply a custom URL here, pointing to a different Parse Server? If not, can I build parse4cn1 from source myself? Or should I be looking for an alternative to Parse?
See these related questions:
Will Parse4cn1 still work after Parse server retirement?
parse4cn1 has some issue when working with Node JS and parse-server open source
I now have some time available and intend to make the change you proposed within the coming month or so and make a release that is compatible with the open source Parse server. If that's too late for you, consider making the changes yourself and contributing back via a Github pull request. The Contributing section of the parse4cn1 repo provides useful tips.
Regarding looking at Parse alternatives, that's a decision you'll have to make yourself based on your needs and timeline. My gut feeling is that the Open Source Parse Server will mature and grow in features in the months leading up to the official retirement of Parse.com.
When I try to execute SALESFORCE QUERY ALL activity(in server), I get java.lang.NoClassDefFoundError. From Google NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time.
But not sure about the exact resolution in Tibco. Is it an issue with the installation of salesforce plugin
I think this due to a missing JDBC driver for your database vendor.

hello i am using ibm worklight application development platform v 6.0.1. I am having a problem with the worklight server, which was working nicely till now. Whenever i try to start the server, it does not and displays the following error:
Worklight server was unable to start within 120 seconds. If the server requires more time, try increasing the timeout in the server editor.
i increased the timeout many times but the problem still persisted. Can anyone help?
thanks in advance.
Please read the following documentation Worklight has provided with the issue described above:
http://www-01.ibm.com/support/docview.wss?uid=swg21668175
A solution is provided below:
To resolve this problem, you can apply one or both of the following workarounds.
Complete the following steps to increase the timeout default value:
1.Open the Servers view.
2.Double-click the Worklight Development Server to open the Overview pane.
3.Expand the Timeouts section.
4.Increase the value in the Start (in seconds) field. Consider doubling the default value; that is, set it to 120 seconds.
Complete the following steps to remove the unnecessary applications from Worklight Development Server.
1.Open the Servers view.
2.Right-click the Worklight Development Server.
3.Select the Add and Remove option.
4.Remove all applications that you do not intend to work on.
After you have made any of these changes to the configuration, restart the server.
As you can see having a lot of applications deployed to your sever may cause the startup time to increase. Have you tried increasing the time beyond 120s as your error indicates?
The Microsoft node.js sql server driver (https://github.com/Azure/node-sqlserver) has not had any commits for 11 months. Anyone know what's going on with this effort? My company is using it actively, but has run across some issues that led me to the repo and the discovery that it seems to have been abandoned. Lots of open bugs also.
Should we give up on this driver and try another? Any recommendations?
Microsoft, please weigh in here.
I emailed the Microsoft main contributor and he was very helpful, although he did admit that officially MS has never declared one way or the other if they were going to continue support. Guess we'll wait and see.
In regards to my original problem - this info may help someone.
I was using queryRaw and listening for events to build the response. This method allows the user to submit multiple sql queries in one request (just separate them with ;). A large text datatype field was getting truncated and I couldn't figure out why. Turns out that the 'more' parameter that is supplied by the driver means that you must concatinate the return data.
Lots of trial and error when figuring out this driver.
Is it possible to build desktop application whit small data base on linux/ubuntu? I have try eclipse+derby- not work, driver load, but can't connect to db. Eclipse +sqlite- not work too, No suitable driver. For a week from now i trying and can't connect to my db. If some1 have WORKING tutorial how to do this in ubuntu+eclipse, pls share. 1 week google, so please if some1 pass this to help me.
Now im using SQLite, i have load the sqlitejdbc-v051.jar in build path and use
Class.forName("org.sqlite.JDBC").newInstance();
but the result is: No suitable driver found for jdbc:derby:/home/vasil/MYDB
Have you taken a look at this site? It seems to be a fairly decent walkthrough. Is the db server that you are trying to connect to running and somewhere accessible to your application?
Take a look at this question. It seems to be very similar to yours. I havn't used derby but I have used many other db servers. It sounds like you dont have the driver on your applications classpath.
Also, this tutorial might also be helpful. It shows how to use jdbc to connect to a db.
