Hi Listers,
Hoping you can offer some comparisons for me in regards to Data Guard APPLY
throughput. We've got some beefy servers HP Superdomes on top rate EMC
storage. We generate up to 8TB of REDO a day. We don't experience Transport
Lags, but do have periods when our Apply Rate (100~MB/Sec) just isn't
enough to keep up with our REDO generation. I've reviewed DOC:

Recovery Performance

But, would like to get some real world metrics from those of you pushing
DG. What are your average Apply Rates?
SQL> select type,item,sofar,sysdate time from v$recovery_progress where
total=0;
TYPE ITEM SOFAR TIME
------------------------------ -------------------- ----------

Media Recovery Average Apply Rate 76301 20160830
12:47:56
Media Recovery Redo Applied 1165240 20160830

Media Recovery Last Applied Redo 0 20160830

Media Recovery Elapsed Time 15638 20160830

Thanks!
