Raiser v0.5 - Committed to Github
I just released an early version of my “raiser” code for Oracle PL/SQL, leveraging OraOpenSource’s logger utility. I’d love to get anyone’s input and help with it. The Github project is https://github.com/gilcrest/raiser
As background, I’ve used the Quest Error Manager (QEM) in my codebase for years, but have recently switched primarily to using logger for most things. There are a few things that QEM does that logger does not… In a highly distributed environment, you really need to be able to raise an exception to a user with a particular error message and unique identifier. If an exception is thrown in one of my applications at 4 in the morning, I need that user to be able to contact support with a unique ID and I need to be able to get a full trace of that error for proper debugging and resolution.
Close to a year ago, I reached out to Martin D’Souza to ask if I could work with him to enhance the logger product to be able to achieve this type of implementation. Martin, being a fantastic product owner, pushed back saying he didn’t want logger to be a “raiser”, but was soon to release a new version of logger that would have hooks in it (in the form of a plugin) that I could use to achieve my goals… Great! So, he did what he said he would - logger 3.0.0 and above has a really cool plugin facility that I’ve utilized to make a “raiser” out of logger.
Also, after reading Dan McGhan’s excellent post about using the APEX_JSON package for creating JSON content, I got the idea to encapsulate multiple fields into the Oracle exception text using JSON… I had been struggling to figure out a good way to be able to give end users multiple data points with just the one SQLERRM output, but I think this works out nicely.
The first order of business is to fix the current getErrorDetails function to parse the JSON SQLERRM and how to work with it…
