Performance issue showing read by other session Event
Hi All,
we are having a severe performance issue in my database when we are running batch jobs.
This was a new database(11.2.0.2) and we are testing the performance by running some batch jobs. These batch jobs included some inserts and updates.
I am seeing read by other session in top 5 timed events and cache buffers chains in Latch Miss Sources section.
Please help me to solve this out.

Issue with "read by other session" and a parallel MERGE query
Hi everyone,
we have run into an issue with a batch process updating a large table (12 million rows / a few GB, so it's not that large). The process is quite simple - load the 'increment' from a file into a working table (INCREMENT_TABLE) and apply it to the main table using a MERGE. The increment is rather small (usually less than 10k rows), but the MERGE runs for hours (literally) although the execution plan seems quite reasonable (can post it tomorrow, if needed).
The first thing we've checked is AWR report, and we've noticed this:
Top 5 Timed Foreground Events
Event Waits Time(s) Avg wait (ms) % DB time Wait Class
DB CPU 10,086 43.82
read by other session 3,968,673 9,179 2 39.88 User I/O
db file scattered read 1,058,889 2,307 2 10.02 User I/O
db file sequential read 408,499 600 1 2.61 User I/O
direct path read 132,430 459 3 1.99 User I/OSo obviously most of the time was consumed by "read by other session" wait event. There were no other queries running at the server, so in this case "other session" actually means "parallel processes" used to execute the same query. The main table (the one that's updated by the batch process) has "PARALLEL DEGREE 4" so Oracle spawns 4 processes.
I'm not sure how to fix this. I've read a lot of details about "read by other session" but I'm not sure it's the root cause - in the end, when two processes read the same block, it's quite natural that only one does the physical I/O while the other waits. What really seems suspicious is the number of waits - 4 million waits means 4 million blocks, 8kB each. That's about 32GB - the table has about 4GB, and there are less than 10k rows updated. So 32 GB is a bit overkill (OK, there are indexes etc. but still, that's 8x the size of the table).
So I'm thinking that the buffer cache is too small - one process reads the data into cache, then it's removed and read again. And again ...
One of the recommendations I've read was to increase the PCTFREE, to eliminate 'hot blocks' - but wouldn't that make the problem even worse (more blocks to read and keep in the cache)? Or am I completely wrong?
The database is 11gR2, the buffer cache is about 4GB. The storage is a SAN (but I don't think this is the bottleneck - according to the iostat results it performs much better in case of other batch jobs).OK, so a bit more details - we've managed to significantly decrease the estimated cost and runtime. All we had to do was a small change in the SQL - instead of
MERGE /*+ parallel(D DEFAULT)*/ INTO T_NOTUNIFIED_CLIENT D /*+ append */
USING (SELECT
FROM TMP_SODW_BB) S
ON (D.NCLIENT_KEY = S.NCLIENT_KEY AND D.CURRENT_RECORD = 'Y' AND S.DIFF_FLAG IN ('U', 'D'))
...(which is the query listed above) we have done this
MERGE /*+ parallel(D DEFAULT)*/ INTO T_NOTUNIFIED_CLIENT D /*+ append */
USING (SELECT
FROM TMP_SODW_BB AND DIFF_FLAG IN ('U', 'D')) S
ON (D.NCLIENT_KEY = S.NCLIENT_KEY AND D.CURRENT_RECORD = 'Y')
...i.e. we have moved the condition from the MERGE ON clause to the SELECT. And suddenly, the execution plan is this
OPERATION OBJECT_NAME OPTIONS COST
MERGE STATEMENT 239
MERGE T_NOTUNIFIED_CLIENT
PX COORDINATOR
PX SEND :TQ10000 QC (RANDOM) 239
VIEW
NESTED LOOPS OUTER 239
PX BLOCK ITERATOR

OR
DIFF_FLAG='D'
DIFF_FLAG='U'
TABLE ACCESS T_NOTUNIFIED_CLIENT BY INDEX ROWID 3
INDEX AK_UQ_NOTUNIF_T_NOTUNI RANGE SCAN 2
Access Predicates
AND
D.NCLIENT_KEY(+)=NCLIENT_KEY
D.CURRENT_RECORD(+)='Y'
Filter Predicates
D.CURRENT_RECORD(+)='Y' Yes, I know the queries are not exactly the same - but we can fix that. The point is that the TMP_SODW_BB table contains 1639 rows in total, and 284 of them match the moved 'IN' condition. Even if we remove the condition altogether (i.e. 1639 rows have to be merged), the execution plan does not change (the cost increases to about 1300, which is proportional to the number of rows).
But with the original IN condition (that turns into an OR combination of predicates) in the MERGE ON clausule, the cost suddenly skyrockets to 990.000 and it's damn slow. It seems like a problem with cost estimation, because once we remove one of the values (so there's only one value in the IN clausule), it works fine again. So I guess it's a planner/estimator issue ... -
Hi
Please help. The situation is that we found the Read By Other Sessions Event occurs and the sessions hang for a week. No new Sessions ID suffers from ths events and Just keep 10 Sessions ID with this event waiting. Our user didn't suffer any performance problem so far.
Our Application layer is Web-based, I believe users related to those sessions are disconnected already. So How come those session ID waits so long !!!!
Thx
KitOur DBA helped me to get the information from the V$Session. Let Session ID = 123. We found that this session has Read by Other Session" event from 17-May up to now every 10 seconds.
DBA gives me the following fields to study

Read by other session wait event
I have some reports in my database that whenever executed by two or more session these reports suffers with read by other session wait event. Tables which are involving in that's query i moves them to other tablespace and then move back to original tablespace. Some how this could solves read by other session wait event. But after some days these problem occur again.
How can i permanently solve this problem??
My db is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Prod
Oracle Block size 4096
ThanksHi there,
Searching for this wait eventin the docs gave this,
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3159
read by other session
This event occurs when a session requests a buffer that is currently being read into the buffer cache by another session. Prior to release 10.1, waits for this event were grouped with the other reasons for waiting for buffers under the 'buffer busy wait' event
Wait Time: Time waited for the buffer to be read by the other session (in microseconds)And a quick google search for the same gave these results in the top.

Hi all,
I have a query with very little cost, it only access one row of the table from a primary key and joins it another table again on primary key column. It doesn't even take a second to complete.
But the problem is when there is another session that accesses data from one of the tables, I encounter "read by other session" wait event, so I wonder if there is a hint to overcome this wait, that will force query to make a disk read without waiting any other working session to put it into buffer cache. Or any other suggestions?

You also say in a later post that the cost of the plan is 11 - if this is correct then your two indexes must have a blevel of about 5 to get that cost from that plan. It seems highly likely that your query doesn't always take the plan you expect and that the "10 minute" versions of this query (which should take less than 0.1 seconds on any reasonable system) is doing a large tablescan to spend so much extra time and report "read by other session". I would check v$sql for multiple child cursors and v$sql_plan (using dbms_xplan.display_cursor if you're on 10g) to check executions plans.

CPU Introduction
I tested my cpu and pushed it at maximum speed to understand where is the limit, can I reach this limit and I've logged precisely all result in graph (See pictures 1).
Intro : I tested my E5-XEON 2687W (8 Cores Hyperthread - 16 threads) to know if programs can use the maximum of it. I used Prime 95 to get the result. // I know this seem to be ordinary, but you will understand soon...
The result : Yes, I can get 100% of my CPU with 1 program using 20 threads in parallel. The CPU gives everything it can !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test...
(picture 1)
Disk Introduction
I tested my disk and pushed it at maximum speed to understand where is the limit and I've logged precisely all result in graph (See pictures 2).
Intro : I tested my RAID 0 556GB (LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed) to know if I can reach the maximum % disk usage (0% idle Time)
The result : As you can see in picture 2, yes, I can get the max of my drive at ~ 1.2 Gb/sec read/write steady !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test to see the impact of transfering many Go of data during ~10 sec...
(picture 2)
Now, I know my limits ! It's time to enter deeper in the subject !
PPBM5 (H.264) Result
I rendered the sequence (H.264) using Adobe Media Encoder.
The result :
My CPU is not used at 100%, the turn around 50%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate seem to be a wave (up and down). Probably caused by (Encrypt time.... write.... Encrypt time.... write...) // It's ok, ~5Mb/sec during transfert rate !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 39 Go RAM free after the test ! // Excellent
~65 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card seem to be a wave also ! (up and down) ~40% usage of GPU during the process of encoding.
GPU Ram get 1.2Go of RAM (But with GTX 680, no problem and Quadro 6000 with 6 GB RAM, no problem !)
Comment/Question : CPU is free (50%), disks are free (99%), GPU is free (60%), RAM is free (62%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
Other : Quadro 6000 & GTX 680 gives the same result !
(picture 3)
PPBM5 (Disk Test) Result (RAID LSI)
I rendered the sequence (Disk Test) using Adobe Media Encoder on my RAID 0 LSI disk.
The result :
My CPU is not used at 100%
My Disk wave and wave again, but far far from the limit !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Buffering time.... write.... Buffering time.... write...) // It's ok, ~375Mb/sec peak during transfert rate ! Easy !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40.5 Go RAM free after the test ! // Excellent
~48 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card = 0 (This kind of encoding is GPU irrelevant)
GPU Ram get 400Mb of RAM (No usage for encoding)
Comment/Question : CPU is free (65%), disks are free (60%), GPU is free (100%), RAM is free (63%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
(picture 4)
PPBM5 (Disk Test) Result (Direct in RAMDrive)
I rendered the same sequence (Disk Test) using Adobe Media Encoder directly in my RamDrive
Comment/Question : Look at the transfert rate under (picture 5). It's exactly the same speed than with my RAID 0 LSI controller. Impossible ! Look in the same picture the transfert rate I can reach with the ramdrive (> 3.0 Gb/sec steady) and I don't go under 30% of disk usage. CPU is idle (70%), Disk is idle (100%), GPU is idle (100%) and RAM is free (63%). // This kind of results let me REALLY confused. It's smell bug and big problem with hardware and IO usage in CS6 !
(picture 5)
PPBM5 (MPEG-DVD) Result
I rendered the sequence (MPEG-DVD) using Adobe Media Encoder.
The result :
My CPU is not used at 100%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Encoding time.... write.... Encoding time.... write...) // It's ok, ~2Mb/sec during transfert rate ! Real Joke !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40 Go RAM free after the test ! // Excellent
~80 thread opened by Adobe Media Encoder (Lot of thread, but it's ok in multi-thread apps!)
GPU Load on card = 100 (This use the maximum of my GPU)
GPU Ram get 1Gb of RAM
Comment/Question : CPU is free (70%), disks are free (98%), GPU is loaded (MAX), RAM is free (63%), my computer is pushed at limit during the encoding process for GPU only. Now, for this kind of encoding, the speed limit is affected by the slower IO (Video Card GPU)
Other : Quadro 6000 is slower than GTX 680 for this kind of encoding (~20 s slower than GTX).

Encoding single clip FULL HD AVCHD to H.264 Result (Premiere Pro CS6)
You can look the result in the picture.
Comment/Question : CPU is free (55%), disks are free (99%), GPU is free (90%), RAM is free (65%), my computer is not pushed at limit during the encoding process. Why ???? Adobe Premiere seem to have some bug with thread management. My hardware is idle ! I understand AVCHD can be very difficult to decode, but where is the waste ? My computer want, but the software not !

Render composition using 3D Raytracer in After Effects CS6
You can look the result in the picture.
Comment : GPU seems to be the bottle neck when using After Effects. CPU is free (99%), Disks are free (98%), Memory is free (60%) and it depend of the setting and type of project.
Other : Quadro 6000 & GTX 680 gives the same result in time for rendering the composition.
(picture 8)
Conclusion
There is nothing you can do (I thing) with CS6 to get better performance actually. GTX 680 is the best (Consumer grade card) and the Quadro 6000 is the best (Profressional card). Both of card give really similar result (I will probably return my GTX 680 since I not really get any better performance). I not used Tesla card with my Quadro, but actually, both, Premiere Pro & After Effects doesn't use multi GPU. I tried to used both card together (GTX & Quadro), but After Effects gives priority to the slower card (In this case, the GTX 680)
Premiere Pro, I'm speechless ! Premiere Pro is not able to get max performance of my computer. Not just 10% or 20%, but average 60%. I'm a programmor, multi-threadling apps are difficult to manage and I can understand Adobe's programmor. But actually, if anybody have comment about this post, tricks or any kind of solution, you can comment this post. It's seem to be a bug...
Thank you.Patrick,
I can't explain everything, but let me give you some background as I understand it.
The first issue is that CS6 has a far less efficient internal buffering or caching system than CS5/5.5. That is why the MPEG encoding in CS6 is roughly 2-3 times slower than the same test with CS5. There is some 'under-the-hood' processing going on that causes this significant performance loss.
The second issue is that AME does not handle regular memory and inter-process memory very well. I have described this here: Latest News
As to your test results, there are some other noteworthy things to mention. 3D Ray tracing in AE is not very good in using all CUDA cores. In fact it is lousy, it only uses very few cores and the threading is pretty bad and does not use the video card's capabilities effectively. Whether that is a driver issue with nVidia or an Adobe issue, I don't know, but whichever way you turn it, the end result is disappointing.
The overhead AME carries in our tests is something we are looking into and the next test will only use direct export and no longer the AME queue, to avoid some of the problems you saw. That entails other problems for us, since we lose the capability to check encoding logs, but a solution is in the works.
You see very low GPU usage during the H.264 test, since there are only very few accelerated parts in the timeline, in contrast to the MPEG2-DVD test, where there is rescaling going on and that is CUDA accelerated. The disk I/O test suffers from the problems mentioned above and is the reason that my own Disk I/O results are only 33 seconds with the current test, but when I extend the duration of that timeline to 3 hours, the direct export method gives me 22 seconds, although the amount of data to be written, 37,092 MB has increased threefold. An effective write speed of 1,686 MB/s.
There are a number of performance issues with CS6 that Adobe is aware of, but whether they can be solved and in what time, I haven't the faintest idea.

Performance issues in Reader 7
Hi,
We have a serious issue with performance in Reader 7. Our client is locked down to this version and we have developed our forms targeting this version in Designer but only recently discovered the performance problems. We seem to have pinpointed the problem to direct rendering in the form. When running the form in adobe reader 9, with direct rendering forced to off, we see the same symptoms that we saw on the adobe reader 7 client. The symptoms are that the memory usage of the acroRd32.exe process rises steadily as we interact with the form and does not come back down. After a time it becomes unusable as it takes about 25 seconds to move between fields. In version 9, with direct rendering on as default, this issue does not occur.
We disabled direct rendering in the XML source using:
<?originalXFAVersion http://www.xfa.org/schema/xfa-template/2.4/ LegacyRendering:1?>
Our client cannot upgrade their reader version and so we are in a very difficult position. If anyone can suggest a way to tackle this performance issue we will be very grateful.
Thanks,
KieranI'm working with Kieran on the same form and I think I have tracked the issue down to a difference between rendering methods in Adobe reader 7 and adobe reader 9. I drew up a benchmark test script and ran it before and after I disabled direct rendering. When runing the form in adobe reader 9, but with direct rendering forced to off. I see the same symptoms that I saw on the adobe reader 7 client.
I disabled direct rendering using:
<?originalXFAVersion http://www.xfa.org/schema/xfa-template/2.4/ LegacyRendering:1?>
Does anyone know of particular objects or methods that might be handled poorly by the legacy rendering mode found in adobe reader 7 (XFA 2.4 and earlier)?
Thanks

Performance issue:Show id and Description for same dimension member
Hi,
I am connecting a cube to another reporting system and i need to show the id of member resulting of a query.My first thought was to use this kind of code (bellow) however when i do the same thing with many dimension (many cross join ),it slow down a lot
my query.So how can i have in the same DImension member showing a description and id ? I also have a lot of statement,so i can't have just two columns in the dimension or i will need to duplication the mdx and i could drop down the performance.
So i am trying to get as a result
Dim1 | Dim2| Dim3| Measure
1 50
32 25.2
and also be able to get
Dim1 | Dim2 | Dim3
| Measure
NameElement1Dim1 NameElement50Dim2
NameElement32Dim3 25.2
Thanks in advance
with MEMBER [Measures].[IdElement] as
<element>.currentmember.properties("KEY")
select
CROSSJOIN({[Measures].[IdElement]},{[METRIC].[Description].[All]}),
CROSSJOIN({[Measures].[value]},{<listmetricmdx>})
} on columns,
<pointofview>
<element_and_function>
<TimeBreakdown>
} on rows
<list_filter_clause>
) as list
where ((ElementName is null AND IdElement=0) OR (ElementName is not null))
<list_condition_metric>
but i have multipleHi Vincent,
In your query, you use CrossJoin in it. Crossjoin function will cause the performance issue if there are a lot of properties that need to be displayed. If you cross-join medium-sized or large-sized sets (e.g., sets that contain more than 100 items each),
you can end up with a result set that contains many thousands of items—enough to seriously impair performance. For the detail information, please see:
http://sqlmag.com/data-access/cross-join-performance
In your MDX query, ensure only retrieval the required data. Here are some useful links for your reference.

Performance issue: Tuning Reading/Writing to a Socket.
I have use case where reading/writing to a Socket is spending over 25% of the time in NativeThread.current() (Called from within SocketChannelImpl) This is a native call and it occurred to me that there might be a Java JNI option which could improve this call in particular.
This may be hprof giving incorrect information, but I don't know how to provide this. YourKit also shows this method as a big hit.
I am not so worried about read0 and write0 as this is directly related to what the use case does.
Can anyone suggest tuning options which might improve the performance of this call?
Does anyone know a way to determine if the information regarding this call is accurate?

'Returns an opaque token representing the native thread underlying the invoking Java thread. On systems that do not require signalling, this method always returns -1.'I think the significant thing is that it is called while synchronized on 'stateLock', so if you have > 1 thread executing writes, the entire sync block will tend to be a bottleneck. I would aggregate the data for current() and read0(), or current() and write0(), and treat it all as I/O time. -
Performance Issue When Read from Internal Table
In my form, I have 6 windows which contain all the header information, which are kept in my gt_header internal table. Since all windows required data from the same internal table, reading the internal table at Initialization for once or, creating the LOOP at each window, which one will be a better choice in terms of performance?
Hi,
you cannot create 6 windows under loop.You can only have loop under a window only.
So create a big window which covers whole area of 6 windows.Create templete under that and write only one loo with text in all those boxes of that templete.

Idle session does consume "some" resources.
Does any consumed resource impact performance?
By which metric at what value is considered any kind of performance issue? -
Performance issues with Imac intel 2011 27 inch..
I have an 2011 imac 3,4 GHz Intel Core i7 with 16 GB 1333 MHz DDR3 RAM.
Since a few months i noticed performance issues with FCPX, where before it would run through video it shows sometimes the color ball. Now the computer is slow in starting up and shutting down also. Ran disk utility but to no avail. I am now considering reinstalling mavericks.
But I ran etrecheck.
here are the results, please who can help me? I use this computer to edit and about everything else.

30EA3- 2.*: Weird performance issues for editing objects
Hi,
I noticed weird performance issues for editing objects: when right-clicking on them in the navigator tree and selecting Edit, you get the old progress dialog "Connected to database XXX". This stays on screen a lot longer than it ever did (last sequence I edited over 30 seconds!).
Cancelling displays a "Error retrieving schemas" dialog, but then opens the Edit dialog correctly. No further side effects noticed, so I think sqldev is adding useless overhead here.
If confirmed, can this be bugged and/or fixed by production?
Thanks,
K.Yes, I mean in context of other hangs reported. This one is a nasty performance issue, but IMO the others are real show stoppers.
Atomic steps are easy; any* Edit (object) action inside the context menu of the navigator or the Edit button of the object viewer.
I took a lot of dumps (every second or so) and came to these findings:

Performance Issue on Select Condition on KNA1 table
Hi,
I am facing problem when i am selecting from the table KNA1 for given account group and attribute9 it is taking lot of time .
Please suggest the select query or any other feasible soln to solve this problem
select
kunnr
kotkd
from kna1
where kunnr eq parameter value and
kotkd eq 'ZPY' and katr9 = 'L' or 'T'.
Firstly i am using in in katr9 then i removed dur to performance issue using read further please suggest further performanace solnHi,
The select should be like:
select
kunnr
kotkd
from kna1
where kunnr eq parameter value
and kotkd eq 'ZPY'
and katr9 in r_katr9. " 'L' or 'T'.
create a range for katr9 like r_katr9 with L or T.
Because while selecting the entries from KNA1, it will check for KATR9 = L and then KATR9 = T.
Hope the above statement is useful for you.
Regards,
Shiva. -
ITunes 7.3.2.6 and Windows Vista Performance Issues
I recently purchased an 80GB iPod, and downloaded iTunes promptly, disregarding all the negative attention about how "iTunes crashes your computer" or "iTunes kills Windows". So far, the only real problem I've had with iTunes is the amazingly poor performance it has on my computer. When iTunes is minimized to the system tray, or compressed into Mini Player mode, it runs better, but not well.
Running in the full mode, the player bogs down my computer substantially. Knowing my laptop isn't a powerhouse, I expected a slight bit of slowdown, since there is some evident with QuickTime.
UPDATE: I've just stumbled across something. Apparently, wiggling my mouse over the iTunes program, iTunes runs about two or three times faster. The moment I stop moving the mouse cursor over the window, the speeds return to slow. It seems to only do this during the "Processing Album Artwork" phase. Bizarre? Very. Any explanations?
I find this to be very annoying, especially when syncing. Syncing my library (which is about five or six gigabytes) takes an amazingly long time. Are there any workarounds, registry hacks, or anything else that can be done? Thanks!
Message was edited by: AtlinkDo you have ReadyBoost enabled on the PC? If so, by way of experiment, try disabling that as per the instructions from the following document:
Troubleshooting iTunes for Windows Vista video playback performance issues
... any help at all with the performance issues?

SNMP SCOM 2012R2 Troubleshooting...... Any Tips?
Hi all, So I'm trying to get my UPS trap alerts in SCOM 2012R2 to work. They work in my SCOM 2007R2 environment but I get nothing in SCOM 2012R2. In SCOM 2012R2 I have also been able to receive traps from our Bluecoat so the rule looks to be working.
