How #garbagecollection works in gateway? Is it automatic and garbage objects got deleted automatically from Gateway heap or we need to enable some settings to get it done.
We are using v9.0 of Gateway.
Gateway uses parallel GC(-XX:+UseParallelOldGC), or so called 'throughput gc', that's why we recommend at least 4 cpu for gateway
Is it auto enabled ? If yes, how can we check if it is enabled and working. Please suggest.
Yes it is auto enabled. You can follow the Garbage Collection section of this KB to monitor - Troubleshooting Gateway application failures, performance concerns, and service outages
