Core i5 'max thread' query

Hi guys,
I've just upgraded my MacBook Pro to a unibody Core i5 model. Loving the speed increase all round in Motion & FCP etc.
Although it's a dual core (2.4), due to the hyper-threading on each core, it registers in Compressor and Shake as having 4 accessible processing threads.
So my question, perhaps obvious as it may sound, is: Should I enable Shake & Compressor to use all 4 threads, or should I cap them to 2?
Only reason I ask is because I'm rendering a project in Shake at the min with 'Max Thread' set to 4, yet it seems really slow. Perhaps it's an abnormally large project? Although it only contains 1 x ProRess 422LT video and one Quicktime SD file. The rest is a concoction of keying nodes and adjustment layers etc.
I've included a screen grab of the project in question (not sure if it helps at all):
http://i1.creativecow.net/u/134316/shakerenderscreen.jpg
It's a bit of a messy project, but the original screen & lighting were quite poor, so I've had to work hard to get it to viewable state I am by no means, a shake-spert
All help & advice appreciated.
Thanks in advance.
Chaz

What I was told and seems to hold true for me is to use one instance for two processors, so for 4 processes (virtual or otherwise), use two instances...

How to get OpenSPARC *prom.bin boot files for one core and two threads?

How can I get OpenSPARC single core two thread files to boot for stand-alone programs and OpenSolaris,
similar to the release download files
design\sys\edk\os\OpenSolaris\proto\1c4t_prom.bin and
design\sys\edk\os\OpenSolaris\proto\1c4t_obp_prom.bin?
How about for other single core but arbitrary thread counts?
Thanks,
sparcMT1

You can modify the 1c4t machine description files in the directory "softsim/t1_fpga/src/xilinx/configs" to create 1c2t machine description files. You have to modify two makefiles "softsim/t1_fpga/src/xilinx/configs/Makefile" and "softsim/t1_fpga/src/xilinx/prom/Makefile" to create 1c2t prom.bin file. You have to also modify the file "softsim/t1_fpga/src/xilinx/include/xilinx_t1_system_config.h" to specify the threads in the core that are enabled. The parameter that specifies the thread mask is "STRAND_STARTSET". It may be possible to only modify STRAND_STARTSET and use the newly compiled 1c4t prom.bin file. OBP may complain that it couldn't start two threads in the core.
You can get the source code for the software at the following url
http://www.opensparc.net/opensparc-t2/downloads.html
The software is in the "OpenSPARC T2 Processor Download for Architecture and Performance Modeling Tools" package.

Does Max threads in Viusal Admin overide Max concurrency in Channels...

Hi All,
Here are the settings for no of JDBC threads in our Java Visual Admin:
AFWCall 10
AFWRecv 5
AFWRqst 10
AFWSend 5
JDBC_http://sap.com/xi/XI/SystemCall 5
JDBC_http://sap.com/xi/XI/SystemRecv 5
JDBC_http://sap.com/xi/XI/SystemRqst 5
JDBC_http://sap.com/xi/XI/SystemSend 5
Now the issue is that even if I put Max concurrency as 1 or 5 in JDBC adapter, I see 5 messages with status 'Delivering' at one time.
So does that mean Max threads in Viusal Admin overide Max concurrency in Channels
Pls advice...on this...

Setting Webserver max-threads in Weblogic

Hi all!
I'm porting an application from Tomcat which uses max-threads to set up the number of maximum concurrent connections to the web server.
I see Oracle Weblogic uses Workmanager instead, but what is the correct way to assign a WorkManager with a MaxThreadsConstraint to the Web server ? (or if it's not possible to the Web server to a Web application)
Thanks
Frank

Assuming that you are porting the application to Weblogic server,if you want to set maximum concurrent connections on the weblogic server,you could configure a workmanager with MaxThreadConstraints.You can either create a Global Workmanager or a scoped work manager on the basis of your requirement.
Please refer to the below link to understand the difference between both and how to go about configuring them:-
http://docs.oracle.com/cd/E11035_01/wls100/config_wls/self_tuned.html
http://docs.oracle.com/cd/E11035_01/wls100/config_wls/self_tuned.html#wp1064810
Now,if you want say for example only 10 concurrent requests on any managed server instance at any point of time,you could configure a Global manager with "Max Threads Constraint" of 10 and target it to the specific instance.
Hope this helps!

Lisa,
I would check the online docs and/or the following HowTos for more details. They are not specific to JRun, but will give you the general process and list or archives and other things to copy and add to the classpath:

How to find out Max threads count for Custom Work Manager??

Hi All,
How to find out Max threads count for Custom Work Manager??
I have created 1 WM & targeted it to a cluster of 2 MS. Later I created Max thread Constraint = 300 & assigned that to my WM.
I need to check how many threads maximum were created by my WM after lets say 1 completed day.
The idea behind that is to understand if .. 300 is enough or need to increase the same way as we do it for JDBC datasource like.. Active connections Max count.. etc.
Any Idea?
regards,
Tanmay

Hi Ashish,
Thanks for your response.
The monitoring page that you are suggesting does not indicate the max thread count reached for a particular WM.
For example, If I have Sample WM with 300 Max Thread Constraint, is there a way for me to check how many threads have been used out of 300??
Any pointers in this regard are appreciated.
Thanks,
Tanmay

Weblogic work manager - Control min./max. threads & fair share

I have an application which is running on Weblogic 10.3.2. I need to be able to control the number of threads the server assigns to this application. The application has 3 MDBs and for each of these MDBs, we need to assign a weight so that that the available threads are distributed among the 3 MDBs according to the weight.
After going through the Weblogic documentation, it looks like I could create 3 work managers with the min. threads, max. threads and fair share. These work managers could be assigned to each of the MDBs. But, this does not control the total number of threads the server assigns to the application.
Question:
Is there a way we can create a work manager with the min. threads and max. threads and assign it to the whole application? This could be used to control the min./max. threads assigned to the application. Then we could define 3 work managers with the fair share and assign them to the individual MDBs.

Hi ,
You can create a work manager with min. threads and max. threads constraints defined. Check this:

WebLogic Max Threads

Hello!
In Tomcat we can specify the attributes of Connector in conf/server.xml like maxThreads, minSpareThreads,maxSpareThreads to control the Thread Pool.
How we can do this in Weblogic? Which is the default value of max threads?
thanks a lot

Hi,
Which Version of WLS are u using? Because till WLS 8.1 We can use Execute Queue Concept to adjust that. We can use " -Dweblogic.ThreadPoolSize=100" JAVA_OPTIONS to do this in WLS8.
But from WLS 9.x onwards we have a new concept called as WorkManager (Which is even recommended). Using this u can assign the MaxThread Constraint not only to the Server ...even u can do it at Application level now.
Please refer to: http://jaysensharma.wordpress.com/workmanagers/ to know how to do it.
<font color=red>NOTE: </font> for any reason if you dont want to use WorkManager thing in your Domain then Please apply the Following JAVA_OPTIONS to use the Old (WLS8.1) Style of Thread Pooling Mechanism:
-Dweblogic.Use81StyleExecuteQueues=true
and
-Dweblogic.ThreadPoolSize=100
Thanks

What is the Default WorkManager Max-Threads-Constraint default value?

Hello,
I know that when I create a new WorkManager the default value for the Max-Threads-Constraint is -1.
But I wonder if this is the case also for the default value of the Default Work Manager?
I would assume that the Default WorkManager has other values set. Couldn't find any reference to that.
Thank you in advance.

It is called as Self-Tuning Work Manager.
It means, it doesnt have a specific value. It varies according to the demand in a specific time.

WorkManager Max thread constraints not applied to MDB

Hi
We have a problem with the workmanager & the max threads constraint in weblogic 10.3. It doesn't seem to apply the constraint at all. The number of beans (message-driven) seems to stop at 16 (max threads is set to 25, applications based work-manager) but it threads the calls far beyond that limit until we run out of database connections. Or at least, that's what it seems to be doing. The server has been restarted and the application redeployed. We've also created a default workmanager with the same constraint but nothing changed. Changing the max-treads-constraint to 1 leads to the same result, 16 beans are created and it seems to create threads until we run out of database resources.
Any ideas on what might be the cause of this ?
Edit: just noticed that the @MessageDriven( name=".. wasn't set. Might that be the cause of this problem ? (not setting the name of the mdb in the @MessageDriven annotation)

The problem is not that it doesn't create more then 16 threads, it's that it seems to be creating more like the 1000+ threads despite the fact that i've set the max-threads constraint in the application specific work-manager (for the specific ejb). It creates 16 ejb's though.
1 - Set the MDB's dispatch-policy to reference a custom work manager (not the default work manager)I did: opened the application, selected the ejb containing the mdb. Configuration - workload, create new workmanager. Selected the global max-constraint workmanager that i've created that says that it should have a restriction of 25 threads. Then both a redeploy and a restart just to be sure.
2 - Set the MDB's max-beans-free-pool to higher than 16 (default is something like 1000)Is this necessary if i set the max-threads constraint. If that's the case, what is the max-threads constraint actually doing ? And another thing, the max-beans-in-free-pool can't be set using the /console if i'm not mistaken which is a bit annoying.
3 - Configure the custom work manager with max threads constraint of higher than 16.I've tried 25 and 1, nothing seems to change. And as i mentioned, i also tried with a default workmanager. It still created 16 ejb's and a WHOLE lot of threads.

Using max select query

    endif.
i need mjahr also from mseg .Top part is working.
    LOOP AT ITAB.
   IF S_KUNNR IS not INITIAL.
    SELECT MAX( MBLNR ) mjahr FROM MSEG INTO MBLNR mjahr
                                   WHERE MATNR EQ ITAB-MATNR

SELECT MAX( MBLNR ) mseg~mjahr FROM MSEG INTO (MBLNR, mjahr)
where matnr eq p_matnr
GROUP BY mseg~mjahr.
WRITE:/ MBLNR, MJAHR.
ENDSELECT.

Update a field based on a max select query

Hi
I am just learning SQL so apologies if this is simple to you guys.
I have a table called [Stock WIP Table] which has duplicates in it. I have an [autonumber] field, a [palletid] field, and a [number5] field. I have the select query working to show the most recent record for each palletID:
SELECT
PalletID,MAX(autonumber)
FROMdbo.[Stock
WIP Table]
GROUPBYPalletID
How do I get the query to now delete all rows that are not in the select query?
Alternatively how could I add update the [number5] field to '1' where the [autonumber] is in the select and I can then delete all records that do not contain a '1' in [number5]
Can anyone help?
Thanks
AJ

Simply this for the DELETE
DELETE t
FROM dbo.[Stock WIP Table]t
WHERE EXISTS (SELECT 1
FROM dbo.[Stock WIP Table]
WHERE PalletID = t.PalletID
AND autonumber > t.autonumber)
No need of UPDATE bit value and then deleting. just above will ensure it gets deleted in single step
another method you may use is this
DELETE t
FROM dbo.[Stock WIP Table] t
CROSS APPLY (SELECT MAX(autonumber) AS MaxID
FROM dbo.[Stock WIP Table]
WHERE PalletID = t.PalletID
)t1
WHERE t1.MaxID <> t.autonumber

WEB Thread Query

Hi All,
The below mentioned query is executing very often.
it seems to be executing every time a web thread initiates and its degrading the performance.
Please provide your suggestion why this is being executed very often.
select a.value lang, b.value terr, c.value cs into :1, :2, :3
from nls_database_parameters a,
nls_database_parameters b,
nls_database_parameters c
where a.parameter = 'NLS_LANGUAGE'
and b.parameter = 'NLS_TERRITORY'
and c.parameter = 'NLS_CHARACTERSET';
begin
select owa_util.get_version into :4 from dual;
exception
when others then
:4 := '1.0.0.0.0';
end;
begin
execute immediate 'declare test boolean;
empty_vc_arr owa_util.vc_arr;
begin test := owa_match.match_pattern(''test'',empty_vc_arr,empty_vc_arr,false);end;';
:5 := 1;
exception
when others then
:5 := 0;
end;
end;

It looks like it is trying to test the database for many things FOR EACH PAGE.. (urgh!!)
Some of those values are going to be mostly static unless a database update is done.
(eg :4 and :5)
You could probably cheat and hard code those values and drop the expensive EXECUTE IMMEDIATE code that is doing nothing more then checking that a particular function exists.
Also, for that first SQL statement, try adding the /*+ cache */ hint.
You may need to use the OCI drivers for it to work.

Daily max(value) query for time period

I am looking to get the maximum value for every 24 hour period for a month. So for example my date range can be defined by...
select to_date('&date','mm yyyy')-1 + level as DateRange
from dual
connect by level <= '&days'
...where I can provide the first date of the month and number of days in the month or a lesser value if less time is required. So, the results of the above query plus 24 for the range. I thought a some googling would provide me what I needed, but my search came up empty.
I was hoping to do something like this...
select utctime, max(value) from table where utctime between....
Any guidance would be much appreciated!
Thanks!
