Maximum and minimum memory utilization of Diyotta controller depends on the configuration parameter call “diserver.java_opts” present in diserver.config file present at “$DIYOTTA_HOME/controller/conf” directory. By default, this value is defined with minimum heap space of 1024mb and maximum of 4026mb as below

diserver.java_opts = -Xms1024m -Xmx4096m

-Xms1024m means controller process will initiate a minimum of 1024mb

-Xmx4096m means controller process can utilize up to 4096 mb.

We can change these settings by modifying diserver.java_opts property in diserver.config directly or we can go to Diyotta admin -> Configurations -> Server Settings -> JAVA_OPTS Settings.
