Hey all, How accurate is ADDM? Today we had a severe performance issue with one our of databases. The ADDM recommendation for that period put the most weight on the following: ---[ADDM Snip]--- Action Investigate the possibility of improving the performance of I/O to the online redo log files. Rationale The average size of writes to the online redo log files was 932 K and the average time per write was 3020 milliseconds. ---[ADDM Snip]--- The problem is, our storage team doesn't see the same level of degredation. Any suggestions? tnx -- http://www.freelists.org/webpage/oracle-l
