java - why some service are lazy while start running jboss server -


the message below indicates jboss did not start 59 services out of 299. why that?

info [org.jboss.as] (controller boot thread) jbas015874: jboss eap 6.3.0.ga (as 7.4.0.final-redhat-19) started in 10290ms - started 261 of 299 services (59 services lazy, passive or on-demand)

this because jboss starts subsystems/services when needed. makes initial boot process faster save memory.

certain services such clustering not needed until deploy application requires clustering (for example, application has <distributable /> tag in web-inf/web.xml file). when particular application deployed , using "ha" profile start jboss, automatically start jboss clustering related services.
