Hi Can someone confirm what I am doing this correct for forcing the GC. I did this on one of our lower environments,
$ sudo -u ignite jcmd 90341 GC.heap_info 90341: garbage-first heap total 2101248K, *used 1261559K* [0x00000005c0000000, 0x0000000800000000) region size 2048K, 172 young (352256K), 3 survivors (6144K) Metaspace used 77269K, capacity 79504K, committed 80892K, reserved 1122304K class space used 7363K, capacity 8207K, committed 8576K, reserved 1048576K ****************************** then ran the below command ****************************** $ sudo -u ignite jcmd 90341 GC.run 90341: Command executed successfully ******************************** $ sudo -u ignite jcmd 90341 GC.heap_info 90341: garbage-first heap total 2097152K, *used 530847K* [0x00000005c0000000, 0x0000000800000000) region size 2048K, 9 young (18432K), 0 survivors (0K) Metaspace used 77195K, capacity 79390K, committed 80892K, reserved 1122304K class space used 7352K, capacity 8187K, committed 8576K, reserved 1048576K The only difference I see here is used 1261559K (before) used 530847K (after) does that mean, it did collect some objects and heap memory freed up ? or any better ways of forcing GC ?
