Archiving data in Sybase IQ from Sybase ASE -

-

what best means of solving following problem:

i have sybase ase database used oltp server. there lot of data inserted database each day , result 'live' tables hold last n days of data (n can vary table table).

i introduce sybase iq server decision support server holding of previous days data reporting purposes.

i nightly job "sync" sybase iq tables in ase i.e. insert new rows, update changed rows not delete of rows outside of n days live table represents.

all ideas welcome!!!

you have develop etl (extract transform load) process.

there lot commercial , free etl products. think best way in case

  1. create rs ase -> ase replication (direct ase -> iq have bad performance)

  2. modify delete function string separate delete operations

  3. periodically truncate insert iq tables second ase db (update poor in iq) via linked server connection

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
