Remove Deprecated Garbage Collection Options in Java 11 or Later

Effective in version 10.5.7 and later, Informatica uses JDK version 11. In Java 11 and subsequent versions, the ConcMarkSweepGC (CMS) and UseParNewGC garbage collectors from JDK version 8 have been deprecated. To maintain compatibility and improve performance, you need to migrate to the recommended garbage collector, G1GC.

Effective in version 10.5.7 and later, some services, such as the Scheduler Service and the Data Integration Service might not start after upgrade due to the deprecated garbage collection options.

To resolve this issue, navigate to the impacted service in the Administrator tool and remove the following options from the advanced properties of the JVM Command Line Options:

-XX:+UseConcMarkSweepGC: Enables the use of the CMS garbage collector for the old generation. CMS is an alternative to the default garbage collector (G1), which also focuses on meeting application latency requirements.
-XX:+UseParNewGC: Enables the use of parallel threads for collection in the young generation.

Verify that G1GC option is enabled by default with the following option:

-XX:+UseG1GC

. If not, add the following G1GC option into the JVM Command Line Options for the impacted service:

-XX:+UseG1GC: Enables the use of the garbage-first (G1) garbage collector. It’s a server-style garbage collector targeted for multiprocessor machines with a large amount of RAM. Prioritizes meeting GC pause time goals while maintaining good throughput for applications with large heaps and low GC latency requirements.

You can specify options, such as

-XX:MaxGCPauseMillis

and

-XX:InitiatingHeapOccupancyPercent

for tuning requirements.

Ensure that you recycle the service to apply the updated configuration in the Administrator tool.
