A short question. We have a ASM disk group which will hold only one table with a BLOB column (almost 2M pictures in this column,total 400TB pics), we tested every AU size from 1M to 64M, find 64M AU size has the best insert performance (of course not so particularly obvious). My question is: Does 64M AU has some known defects? Thanks for any feedback. 11.2.0.2 Oracle single instance on OEL6 x86-64. -- Zhang Leyi (Kamus) <kamusis@xxxxxxxxx> Visit my blog for more: http://www.dbform.com Join ACOUG: http://www.acoug.org Sent with Sparrow (http://www.sparrowmailapp.com/?sig) -- //www.freelists.org/webpage/oracle-l
