Eager Loading

Stelt0 — Wed, 21 Dec 2016 09:19:58 -0500

Hello Ivy Team,

In my project, I had to switch from the default Eager loading to the Lazy loading of the Entity classes. The reason was that the queries were not optimized. Now I have the following problem, every time I try to inspect the variables in debug mode, the Designer is throwing errors and it is almost impossible for debugging:

How to debug Ivy Script?

RemiMorin — Mon, 14 Nov 2016 20:41:45 -0500

Hi, I'm currently extending a existing Ivy application. I face the problem of being unable to debug (trace) Ivy script.

Is there some tooling? maybe some trick to output directly into the "runtime log" of the designer?

I've already hack the logger to display SQL and such. I'm familiar with web development, java, tomcat and most of the ecosystem. I just have hard time tracing the logic in process. I currently have a bug with Ivy add on, I replace all parameter values one by one with hardcoded values to see what is going on. I've figure out which variable is erroneous but can't figure out what's in it.

Debugging a RD process running on a remote server

A1234 — Fri, 14 Nov 2014 09:58:28 -0500

Hello,

I followed the directives to debug a remote server, as described in How can I debug my Java class in the Designer?.

That works well, I can set breakpoints on Java class statements, and debug the code.

I would like to know if it possible to also debug a RD process by setting breakpoints on process elements?

I don't see how to have my breakpoints stop when they are executed. I started the engine, but that does not work.

How can I take a thread dump of Xpert.ivy Server?

To analyze deadlocks in my code (and in Xpert.ivy) or endless loops it is useful to get a thread dump.

The thread dump contains information about each thread, the locks it owns, the locks it is waiting for and the whole java callstack of the thread. A thread dumps looks like this:

"http-8081-8" daemon prio=6 tid=0x000000001cd71000 nid=0x1124 in Object.wait() [0x000000001e24f000]
   java.lang.Thread.State: WAITING (on object monitor)
    at java.lang.Object.wait(Native Method)
    - waiting on <0x00000004d208fae8> (a org.apache.tomcat.util.net.JIoEndpoint$Worker)

How can I debug my Java class in the Designer?

I use a lot of Java code in my Ivy projects and I desperately need to debug them. If I set a break point in the source code, the execution does not stop at the break point.
