Detecting ObjectDB alive

2016-11-18 01:03

Hi, I'm wondering how best to be able to detect if ObjectDb Server is alive?


a) from a java process - I'm guessing you could try and grab a Persistence Manager and/or listen for a Disconnection Exception??

b) from a NodeJs runtime - I'm guessing you could either try and grab the ObjectDb server port and that won't be possible as long as the Objectdb Server is running. Is there a way to polling server from TCP and/or HTTP ?  

I guess there is also the linux shell, i.e: checking the process, but I'd prefer to avoid that.

All these three options are possible, but maybe the best way to see that ObjectDB is actually functioning (and not just running and holding a port) is to test it periodically, e.g. by obtaining an EntityManager, making some operation against the database and then closing the EntityManager.

Please read carefully the posting instructions - before posting to the ObjectDB website.

  • You may have to disable pop up blocking in order to use the toolbar (e.g. in Chrome).
  • Use ctrl + right click to open the browser context menu in the editing area (e.g. for using a browser spell checker).
  • To insert formatted lines (e.g. Java code, stack trace) - select a style in the toolbar and then insert the text in the new created block.
  • Avoid overflow of published source code examples by breaking long lines.
  • You may mark in paragraph code words (e.g. class names) with the code style (can be applied by ctrl + D).
  • Long stack traces (> 50 lines) and complex source examples (> 100 lines) should be posted as attachments.
