AC v4.7.4 release highlights

The AC v4.7.4 release includes the following enhancement and bug fix.

Enhancement​

  • Migration Behaviour Control
    During object migration from AC v3.x to AC v4.x using the migration Helm chart, you now have greater control over activity ownership.
    If you prefer not to override activity ownership, configure the following environment variable in the environmentVariables section of your migration values.yaml:
    **SKIP_OVERRIDE_USER=true
    **

    WarningBefore proceeding with this action, ensure that the same users in the source environment are also available in the target environment. 

Bug fix​

  • **Improved Memory Management
    **Application memory management has been enhanced by resolving an issue where memory was not being released properly during large file processing.
    This fix ensures:
    • Reliable job completion under high-volume processing conditions
    • Prevention of intermittent failures caused by excessive memory consumption

  • **Java Options Optimization
    **JVM configurations have been updated to improve memory handling and overall performance.

  • Additional JAVA_OPTS Configuration:

    • -XX:+UseZGC
    • -XX:+ZUncommit
    • -XX:ZUncommitDelay=60
    • -XX:+UseContainerSupport
    • -XX:MaxRAMPercentage=75.0
    • -XX:MetaspaceSize=256m
    • -XX:MaxMetaspaceSize=512m
    • -XX:ReservedCodeCacheSize=256m
    • -XX:MaxDirectMemorySize=2g

These configurations help to:

  • Optimize resource utilization
  • Improve memory release and garbage collection efficiency
  • Enhance performance in containerized environments
