Debug mode very slow from eclipse - 20.0.0.6 compared to 19.0.0.3

  • 1.  Debug mode very slow from eclipse - 20.0.0.6 compared to 19.0.0.3

    Hi,

    I am migrating various applications from Liberty v 19.0.0.3 to 20.0.0.6.

    While running 20.0.0.6 server from Eclipse (2020-03) on a debug mode, the server takes a lot of time to start the application. With one particular monolith application the 20.0.0.6 server in debug mode takes 20 mins longer than 19.0.0.3.

    While comparing the server.bat file on the runtime, I notice the following is missing from the startup script:

    -Dcom.ibm.websphere.ras.inject.at.transform=true

    One I manually add this, the performance gets better and is in line with 19.0.0.3.

    Is this something that's missed from the 20.0.0.x binaries?

    I ran into the same issue today. Did compare with 19.0.0.3 and re-added -Dcom.ibm.websphere.ras.inject.at.transform=true to JAVA_DEBUG in /bin/server . Overall performance is back to as you would expect from a debugging server.

    Can somebody enlighten us about this property which should be set when debugging according to docu https://www.ibm.com/docs/en/was-liberty/base?topic=manually-customizing-liberty-environment .
