Log file parallel write is writing redo records to the redo log files from the log buffer. In this case, it means the database is not the bottleneck, its spent alot of time WAITING for you to tell it to do something.I found it, but the explanation of P1-P3 in v$session_wait is so weak. The wait time is the wait for LGWR to complete multiple log file writes. In this case, this is a non-idle condition, we were not idle (as an entire process -- client database).... In some some systems ( ex: Silicon Graphics), even disk_asynch_io = true, does not enable asynch i/o because of some hardware requirements.I am looking at some oracle views (v$system_event, v$session_event & v$session_wait) to make sense of the info gathered. It basically means that it can happen as the result of an idle wait (which is "innocent") or as the result of a non-idle wait (we were REALLY truly waiting for this to finish before doing something else) For example: [email protected] It is showing that we are idle However, its not ALWAYS an idle wait event.Top waits now are: db_file_sequential_read log_file_parallel_write io done. Say you are running a pro*c app you wrote, its a batch program. You look and see that the sql*net message from client is HUGE -- guess what that means.I've seen lot's of questions on the internet about these, but no answers. Tom, In our production system , while executing one procedure it take very long time to execute it when i run the query individualy it run fast..Can you tell if any of the PX Deq waits are interesting or significant/correctable? so i traced the session and found that my SQL*Net message from client waited that much time... SQL select * from v$session_event where sid=88; call count cpu elapsed disk query current rows ------- ------ -------- ---------- ---------- ---------- ---------- ---------- Parse 1 0.00 0.03 0 0 0 0 Execute 18480 36.69 88.65 0 0 0 0 Fetch 18480 8.77 20.28 0 73920 0 18480 ------- ------ -------- ---------- ---------- ---------- ---------- ---------- total 36961 45.46 108.96 0 73920 0 18480 Misses in library cache during parse: 0 Optimizer goal: CHOOSE Parsing user id: 324 (recursive depth: 1) SID EVENT TOTAL_WAITS TOTAL_TIMEOUTS TIME_WAITED AVERAGE_WAIT --------- ------------------------------ ----------- -------------- ----------- ------------ MAX_WAIT --------- 3 88 SQL*Net more data to client 1 0 0 0 0 88 SQL*Net message from client 304 0 680756 2239.3289 382821 SQL select * from v$session_wait where sid=88; SID SEQ# EVENT --------- --------- ------------------------------ P1TEXT P1 P1RAW ---------------------------------------------------------------- --------- -------- P2TEXT P2 P2RAW ---------------------------------------------------------------- --------- -------- P3TEXT P3 P3RAW WAIT_TIME ---------------------------------------------------------------- --------- -------- --------- SECONDS_IN_WAIT STATE --------------- ------------------- 88 2132 SQL*Net message from client driver id 675562835 28444553 #bytes 1 00000001 0 00 0 136 WAITING Thanks in advance and Your doing great job tom........

I realize that 2 parallel operations can take different amounts of time to finish their tasks and that some waits cannot be avoided (or even considered bad), I just don't know which ones.The Ask TOM team is taking a break over the holiday season. IO done, this event is used by the IO slave processes (oracle Innn) when waiting for slave IO processes to complete a request or by idle slave IO processes waiting for work. COM select event, time_waited 2 from v$session_event 3 where sid = ( select sid from v$mystat where rownum = 1 ) 4 and event = 'SQL*Net message from client' 5 / EVENT TIME_WAITED ---------------------------------------------------------------- ----------- SQL*Net message from client 925 Here the sql*net message from client is a true IDLE wait event.Thanks for being a member of the Ask TOM community. This year we've answered over 2800 of your questions and followed up on 3500 reviews. One of our systems has serious problems on certain days. This wait event is used in both IDLE and NON-IDLE conditions so can be very misleading. COM select event, time_waited 2 from v$session_event 3 where sid = ( select sid from v$mystat where rownum = 1 ) 4 and event = 'SQL*Net message from client' 5 / EVENT TIME_WAITED ---------------------------------------------------------------- ----------- SQL*Net message from client 263 [email protected] As we sit in sqlplus, it just keeps on ticking up.....Product datasheet Upgrade Price Guarantee Compatible with Windows 10, 8.1, 8, 7, Vista and XP, 32 Bit / 64 Bit Editions New language versions: Chinese - Lithuanian - Japanese - Polski - Romanian - Spanish - Czech Update Star is compatible with Windows platforms.Update Star has been tested to meet all of the technical requirements to be compatible with Windows 10, 8.1, Windows 8, Windows 7, Windows Vista, Windows Server 2003, 2008, and Windows XP, 32 bit and 64 bit editions.
