rdbms - what exactly the undo information lives in oracle? -

some docs says, there "undo tablespaces" implies should create tablespace undo imformation. some docs says, there "undo segment" implies undo information lives in normal tablespaces , use of it's segment. so, undo information lives , organized? earlier releases of oracle database used rollback segments store undo. oracle9i introduced automatic undo management, simplifies undo space management eliminating complexities associated rollback segment management. oracle recommends (oracle 9i , on words) use undo tablespace (automatic undo management) manage undo rather rollback segments. when creating undo tablespace, these automatically created: n undo segments (based on sessions parameter value) named _syssmun$ owned public (usable ops configuration) not manually manageable

clojure - 'get' replacement that throws exception on not found? -

i'd access values in maps , records, throwing exception when key isn't present. here's i've tried. there better strategy? this doesn't work because throw evaluated every time: (defn get-or-throw-1 [rec key] (get rec key (throw (exception. "no value.")))) maybe there's simple method using macro? well, isn't it; has same problem first definition, if evaluation of throw happens later: (defmacro get-or-throw-2 [rec key] `(get ~rec ~key (throw (exception. "no value.")))) this 1 works letting get return value (in theory) never generated other way: (defn get-or-throw-3 [rec key] (let [not-found-thing :i_would_never_name_some_thing_this_021138465079313 value (get rec key not-found-thing)] (if (= value not-found-thing) (throw (exception. "no value.")) value))) i don't having guess keywords or symbols never occur through other processes. (i use gensym generate special value of...
