-

i created new dsn on local machine. after doing that, following error message. can advice on how fix this?

connection<- odbcconnect(dsn="oradb1",uid="username",pwd="password") warning messages:     1: in odbcdriverconnect("dsn=oradb1;uid=username;pwd=password") :       [rodbc] error: state na000, code 12504, message [microsoft][odbc driver oracle][oracle]ora-12504: tns:listener not given service_name in connect_data     2: in odbcdriverconnect("dsn=oradb1;uid=username;pwd="password") :        [rodbc] error: state 01000, code 0, message [microsoft][odbc driver manager] driver doesn't support version of odbc behavior application requested (see sqlsetenvattr).     3: in odbcdriverconnect("dsn=oradb1;uid=username;pwd=password") :        odbc connection failed

you need make sure if works basic r command line first.

based on error msg, system(or r studio) not recognize new dsn , driver. did put user dsn or system dsn?

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
