oracle10g - How do I get the number of inserts/updates occuring in an Oracle database? -


how total number of inserts/updates have occurred in oracle database on period of time?

assuming you've configured awr retain data sql statements (the default retain top 30 cpu, elapsed time, etc. if statistics_level 'typical' , top 100 if statistics_level 'all') via like

begin   dbms_workload_repository.modify_snapshot_settings (     topnsql => 'maximum'   ); end;

and assuming sql statements don't age out of cache before snapshot captures them, can use awr tables of this.

you can gather number of times insert statement executed , number of times update statement executed

select sum( stat.executions_delta ) insert_executions   dba_hist_sqlstat stat         join dba_hist_sqltext txt on (stat.sql_id = txt.sql_id )        join dba_hist_snapshot snap on (stat.snap_id = snap.snap_id)  snap.begin_interval_time between <<start time>> , <<end time>>    , txt.command_type = 2;  select sum( stat.executions_delta ) update_executions   dba_hist_sqlstat stat         join dba_hist_sqltext txt on (stat.sql_id = txt.sql_id )        join dba_hist_snapshot snap on (stat.snap_id = snap.snap_id)  snap.begin_interval_time between <<start time>> , <<end time>>    , txt.command_type = 6;

note these queries include both statements application issues , statements oracle issues in background. add additional criteria if want filter out sql statements.

similarly, total number of distinct insert , update statements

select count( distinct stat.sql_id ) distinct_insert_stmts   dba_hist_sqlstat stat         join dba_hist_sqltext txt on (stat.sql_id = txt.sql_id )        join dba_hist_snapshot snap on (stat.snap_id = snap.snap_id)  snap.begin_interval_time between <<start time>> , <<end time>>    , txt.command_type = 2;   select count( distinct stat.sql_id ) distinct_update_stmts   dba_hist_sqlstat stat         join dba_hist_sqltext txt on (stat.sql_id = txt.sql_id )        join dba_hist_snapshot snap on (stat.snap_id = snap.snap_id)  snap.begin_interval_time between <<start time>> , <<end time>>    , txt.command_type = 6;

oracle not, however, track number of rows inserted or updated in given interval. won't able information awr. closest try leverage monitoring oracle determine if statistics stale. assuming monitoring enabled each table (it default in 11g , believe default in 10g), i.e.

alter table table_name   monitoring;

oracle periodically flush approximate number of rows inserted, updated, , deleted each table sys.dba_tab_modifications table. show activity since statistics gathered on table, not activity in particular interval. could, however, try write process periodically captured data own table , report off that.

if instruct oracle flush monitoring information memory disk (otherwise there lag of several hours)

begin   dbms_stats.flush_database_monitoring_info; end;

you can approximate count of number of rows have changed in each table since statistics last gathered

select table_owner,        table_name,        inserts,        updates,        deletes   sys.dba_tab_modifications

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
