process working set info in linux i finding working set size of process in proc folder link can find working set size in /proc don't know how know. knew rss working set size rss different working set size can know working set size using /proc/[pid]/statm ? i don't believe /proc/[pid]/statm gives wss, or /proc/[pid]/status matter. wss number of pages process needs in memory keep "working". rss number of pages of process reside in main memory. so rss >= wss. meaning rss may include pages process doesn't need right now. maybe used stale pages in past. from understanding of linux internals, kernel doesn't keep track of wss on per-process basis. wss involved track continuously , doesn't have exact formula. rss simpler calculate, kernel reports that. note if sum of wss of processes greater or equal main memory size (i.e. system thrashing or close thrashing) rss equals wss because pages absolutely needed process kept in main memory. g

i'm trying figure out how sort on multiple fields in grails 3, 1 of may or may not null. have book domain: class book { string title string sorttitle static constraints = { title blank: false sorttitle nullable: true } } books titles "the peripheral" have sorttitle of "peripheral, the", otherwise sorttitle null. want books sorted sorttitle if 1 exists, otherwise title . i found other similar questions, none nullable field. happen have pointers in right direction? you can use: coalesce(book.sorttitle, book.title) here have official hibernate documentation.
