Benefit of rebalance

Hi folks,
what are benefit of rebalance in ASM?
thanks & regards.

Hi,
ASM Rebalancing >>>>>>>>>>>>>>>>>>>>>>>
    "Rebalancing" is the process of moving file extents onto or off of disks for the purpose of evenly distributing the I/O load of the diskgroup
    It occurs asynchronously in the background and can be monitored
    In a clustered environment, rebalancing for a disk group is done within a single ASM instance only and cannot be distributed across multiple cluster node to speed it up
    ASM will automatically rebalance data on disks when disks are added or removed
    The speed and effort placed on rebalancing can be controlled via a POWER LIMIT setting
    POWER LIMIT controls the number of background processes involved in the rebalancing effort and is limited to 11. Level 0 means no rebalancing will occur
    I/O performance is impacted during rebalancing, but the amount of impact varies on which disks are being rebalanced and how much they are part of the I/O workload. The default power limit was chosen so as not to impact application performance
Thanks,
Rajasekhar

Persistence-rebalance is not working after adding new cotexts

Hi,
I had the following problem.
The customer has two ACE20 modules. These modules are configured with some contexts. These contexts are configured and working. Last week I created and configured new three contexts without modifying current contexts. After this change, the customer had a problem with cookie insertion in the one of the current cotext. There was no configuration change (the persistence-rebalance map was configured and assigned to the policy-map) in this context. Only one solution of this problem was removing and adding again the parameter map into policy map. After this change the cookie insertion is working well. So it seems like a bug, but I didn't find it in the bug toolkit. Is this behaviour correct?
Thanks

How do I know if my MBP will benefit from heatsink paste reapplication?

Dear Mac Users
I know the theme of hot MacBook Pro's has been done to death, but I would like to add my two pennyworth with respect to the specific question: How do I know if my MBP will benefit from reapplication of the heatsink compound? I have trawled numerous very long threads here and not found a satisfactory answer. The reapplication of the heatsink paste is a bit of a schlep and not without some risk of breaking it, so it would be good to know if the benefit is worth the risk.
One common question is: "Are my MBP temperatures unusual?". A useful mac temperature database can be found at the following link:
http://www.intelmactemp.com/list
Consulting this list should set some parameter space for many users - there does seem to be considerable variability - suggesting highly variable quality of heat sink paste application by Apple. In my particular case I have an early 2011 MBP (i7, quad core, 2.2GHz). This certainly ran very hot. I even had a burn on my thigh from it, which took a while to heal. I know, they are notebooks, not laptops, but still . . . . To put very hot into perspective, the CPU was sitting at over 60C at idle, and whole case would be hot to the touch, such that resting your hands on it was uncomfortable. And yes, the computer was idling, there were no rogue processes chewing up cycles. At full load, the CPU would run at 90C and the whole thing would get very hot. I avoided running major projects or rendering jobs on it to preserve it from heat fatigue - the warranty is now up.
My first attempt at reducing the temperatures, was to clean it. The clue was in the USB/Firewire etc ports. All were very fluffy, which suggested that there was a lot of crud in the heatsink fins. Fixing this was simple; adopt anti-static precautions; remove the back panel; blow air into the exhaust vents at the base of the screen. Numerous large fluff bunnies popped out of the fans and elsewhere. Alternatively, you can unscrew the two fans and partially lift them out (without removing the power cables to the motherboard). Major fluff on the heatsink fins can then be tweezered out, prior to blowing it through, to ensure all debris is removed. I did this subsequently on my Core 2 Duo MBP. After defluffing the idle i7 CPU temperatures dropped from 60C to 43C, but perhaps of more importance was that the whole case was much cooler and the keyboard temperature was close to ambient - much nicer to use.
So that fixed the major heat problem. However, the question remained, would I see any further improvements by stripping the thing down and reapplying the heatsink paste? What I was looking for in this forum was a rule of thumb based on temperature measurements to help me make an informed decision on whether to strip the thing down. As my machine was out of warranty, I wasn't worried about voiding that. Also, where I am there is zero support (Africa), so Genius Bar or similar was not an option. But jiggering a 14month (very expensive) laptop was not something I wanted to do for thrills. The data in many of the posts did not provide any answers. In the end I made some measurements and decided to do the fix. The step by step instructions I followed were very clear and can be found for many Macs/models at:
http://www.ifixit.com/Device/Mac
This guide made life a lot less stressful, as pulling a connector the wrong way could trash the motherboard, and those connectors are so very tiny and fragile. It is very important to take it slow and follow each step to the letter (and not skip steps inadvertently). My before and after heatsink paste fix temperature data are shown below. The idle temps are improved, while the full load temps look like a marginal improvement. However, CPU temperature is not the only story. Certainly after the fix, the whole case is generally cooler, so the heat extraction system is working better. Also, the CPU before and after temps are quite similar at full load, but that assumes the CPU is running at the same power. I do not know enough about the i7 architecture to say if the before speed was being limited by heat, while in the after case the turbo-boost was able to run out to the maximum. Unfortunately, I didn't do any CPU performance tests. So, based on temperatures alone, it looks like a marginal improvement, but it is certainly making a difference to case temperatures.
Note all temperatures were measured at an ambient temperature of 20C on a flat, hard surface using Marcel Bresink's Temperature Monitor. Fan speed was measured using the Fan Control software - set to allow firmware control at idle.

Heat Sink 3 50C
Fan Speeds 6200rpm
Back to my original question: How do I know if my MBP will benefit from reapplication of the heatsink compound? I think temperatures alone will not give a good answer - mainly because the CPU probably has variable output - due to turbo boost. One thing I did notice is that the temperature response of the CPU when it gets switched to full load, does vary according to the quality of the heatsink paste. With the original Apple paste, when I switched the CPU to full load (from idle) the temperature of the CPU went up to its maximum almost instantaneously and stayed at that level ie the graph of temperature vs time was a step function. This suggests that the CPU may be controlling the temperature by throttling itself. Otherwise, as the heatsink warmed up, the CPU should also rise in temperature - mine stayed bang on 90C and fluctuated only by a degree either side. After application of heat sink paste, the CPU has a much larger effective thermal mass and consequently heats up much more slowly. Turning the CPU up to maximum from idle resulted in the temperature climbing to a maximum over about 3-4s. After peaking at around 92C it dropped back as the fans kicked in, to around 86C.
So perhaps one way of assessing the quality of your heatsink paste is to ramp the CPU to maximum from idle and look at the shape of the temperature profile. A step function suggests a lousy job and benefit may be had from reapplication. A more gently sloping profile, followed by a dip due to the fans kicking in, may suggest you are in good shape. Obviously, this presupposes that your Mac temperatures are not insanely hot to start with (i.e. high 90sC+). In which case, if defluffing doesn't do the job, then new heatsink paste is almost certainly required.

I'm sorry but this is too funny to pass up.

Error in updating benefit plan IT0171...for CE

Hi All,
Presently in SAP, the benefit main assignment for concurrent employee is done using the transaction for benefit workbench.
I need to updated Infotype 0171 for concurrent employee from my Z-program. But here I am facing an eror which is given below:
1. I am change the data for IT0171 using HR_INFOTYPE_OPERATION (eg. CE 40, has 2 assignments pernr 40 and 52). Now the default in the benefit workbench is 40, so when i am changing assignment from 40 to 52, I am passing BENGR and BSTAT from 40 to 52 and trying to update 40 with blank value.
Bt here i am getting error in IT0171 for pernr 40, tht BAREA, BENGR and BSTAT cannot be updated with blank value (whereas the same happens in benefit workbench)
2. I am not able to solve this coz I am using HR_INFOTYPE_OPERATION in my program and this FM is also used in HRBEN00CEWB.
PLease help

Will I Benefit By Upgrading Video Card Only? or Complete New Build?

I, too, was wondering if I might benefit from upgrading only the graphics card. My current system:
Windows 7 Ultimate 64-bit SP1
CPU
   Intel Core i7 2600K @ 3.40GHz 43 °C
   Sandy Bridge 32nm Technology
RAM
   32.0GB Dual-Channel DDR3 @ 799MHz (10-10-10-27)
Motherboard
   ASUSTeK COMPUTER INC. P8Z77-V PRO/THUNDERBOLT (LGA1155) 37 °C
Graphics
1535MB NVIDIA GeForce GTX 580 Amp! (ZOTAC International) 44 °C
Storage
CACHE & PREVIEWS 111GB ATA KINGSTON SH100S3 SCSI Disk Device (SSD) 34 °C

     DNxHD 220 Footage
     DSLR Footage
     AVCHD
   Optical Blu-ray Drives
   HL-DT-ST BD-RE BH16NS40 ATA Device
I was shooting HDV when I built this system, but am now shooting with a Canon EOS C100 and a 5D Mk III DSLR. I record DNxHD externally onto Atomos Ninja Blade.
Although this system seems pretty well balanced, I have never been able to do much more than basic editing with Premiere's real-time effects, since anything else (like Noise reducers, MB Looks and Red Giant effects) pretty much cripples my system playback, rendering, exporting. Even with HDV footage I was never satisfied with performance. I recently upgraded my storage from a 2-disk RAID 0 to a 4-disk 16 TB RAID 0, which seems to have helped transfer rates a little.
I wonder if the GTX 580 is defective. It seems to run pretty hot under load at 60 degrees or more unless I boost fan speed to the max. I cannot change any GPU clocks speeds or other settings from default without the display crashing. That is why I am considering a new GPU. I plan to build or buy a new PC within the next year, anyway, but it would be great if a GPU could extend the life of this one.
As for a new complete built, I need to know if now is the time to do it. Or, is there some new motherboard/processor series on the horizon that I should wait for? The frustrating thing about these kinds of forum threads is that the information is quickly dated and obsolete.

I am hardware accelerated.
As for the GPU temperature. The NVidia control panel monitors voltages and temperatures, but gives no reference for what the normal operating temperature should be. How do I know if the GPU is running too hot? The same goes for the rest of the components. I'm sure you professional computer builders have that kind of info available, but how do the rest of us know when something is wrong with a component? Is there a troubleshooter I can download? or a chart that shows a normal range of numbers?
When I first built this computer 3 years ago or so, I had a GTX 470, but it fried a year later and I replaced it with the GTX 580, which gave me a good boost in performance over the 470. It would seem that a 700 series GPU would give me better performance over the 580 - with a vast in increase in CUDA cores and more RAM, etc. But, I have read in this forum and other places that a newer model GPU alone will not make much difference, which makes absolutely no sense. If that's true, then what's the point of having all those additional CUDA cores?

Cannot find source code for Employee Benefit application

Hello,
I am trying to find the Employee Benefit Sample Application which used to be provided by Oracle at http://otn.oracle.com/sample_code/products/ias/content.html. Unfortunately I couldnât find the source code anywhere, neither by searching through oracle sites, nor through the internet.
Could someone please help me get it, since I just started working on applications based on this model and it is really important for me to have a complete example that works.
Thanks in advance,
Stefanos

Hello,
This sample application used to work on older versions which is no longer supported. This is the reason, it has been removed.
Thanks.

What is the benefit of using BC4J?

Folks,
After working with BC4J for three months, I still can not convince my manager to use BC4J. His major arguments are:
1. Which applications or web sites are implemented using BC4J? Are they real application or just a demo. For the time being, I even can not show him a demo, not to say any real web applications.
2. His developers told him that the O-R mapping provided by BC4J, which is probabably one of the key benefit of BC4J can be easily coded manually with a couple of days work for the current task and we have the full control over our own code while BC4J is not an open source and the lack of the support from Oracle really worries him.
Can someone in Jdev team give me a clear evidence to convince him?
Thanks,
Yibing

[*]With regard to struts integration with BC4J, I have done some investigations of the new release and know that BC4JActionForm is only good for simple view and does not work for a joint table view as I have reported a few days ago in this group and no response is received yet.
This should not be the case. Should work for any view object. View objects can contain join queries with any number of updateable tables in them. Please email me the URL to the forum posting so I can track down the issue.
[*]I have been recently told indirectly from Oracle that the consulting group at oracle are not using BC4J and instead they think that BC4J only applies to simple applications with limited number of tables and relationships.
This is plain incorrect. We have very large applications using BC4J both internal in Oracle Applications, for Oracle iLearning, and many external customers. Many of these projects have involved (and are currently involving) Oracle Consulting. Not sure where got this information, but it is incorrect.
[*]Other commecial O-R mapping products such as top-link should be used for large applications
The key difference between Oracle9i TopLink and Oracle9i BC4J has nothing to do with the size of your project. The fundamental difference is that toplink is for customers who have already written a custom application framework and who require just a persistence architecture, because they've already hand-written code to implement all of the other J2EE design patterns that are required to build real J2EE applications.
Conversely, BC4J is for customers who want a complete J2EE Application Framework (and tightly integrated, award-winning toolset to go with it) to avoid having to write, test, debug, and maintain their own application framework.
There is simply no evidence to backup your statement that BC4J only works for small applications. I am aware of at least 20 (and by now after a summer full of training additional Oracle Apps development teams in BC4J, perhaps over 30) that are using BC4J for full-scale, self-service J2EE web applications. Our BC4J reference info pages (link in this thread above) have references to customers who are using BC4J for large applications as well.

Hope this helps.

I have a MacBook Pro, and AppleTV, and an iPhone 4s. I'm not too familiar with iCloud, but I know it can benefit me

I know that iCloud could be hugely beneficial to me, but I'm not sure I understand everything about it.
I keep all of my music, TV shows, movies, podcats, etc. on a seperate hard drive. I have entire series of a TV show (complete with 9 seasons) that I bought from iTunes, so needless to say they take up quite a bit of space. For that reason, I moved all of my media files to my separate hard drive to make sure my MacBook Pro would have less memory and space used and run smoother. All of my music is on there as well. I also have my entire music library on my iPhone 4s (not all of the tv shows, obviously). I can automatically play my TV shows on my AppleTV simply by going to my purchased TV shows. I know that with all of the media I have, using iCloud would benefit me greatly, but I'm just really confused about the entire concept. If someone would be so kind as to lay it out for me so that I understand it's functions, I'd greatly appreciate it!

How can i get a macbook with the configration i want from apple retail store so that i can benefit from tax free service at the airport ?

hi all, i just want to know how can i get a MacBook pro with the configuration i want from apple retail store (in Munich) and not by order it online because in this case i will not be able to benefit from Global blue service for tax free from the airport when i leave Germany.
thanks in advance.

You should have probably found out more specifically from the Apple Store just how you could do it online. The obvious solution is to order it from the Apple Danish website store, but I don't know if they ship internationally.

Is there any benefit for me to use smart previews if my Lightroom 5 catalog, previews and media are all on the same external USB HD?

I keep everything on 1 External USB3 HD so that I can pug it into my Mac at home or my PC at work and just keep working without syncing anything to the local machine. So is there any benefit with Smart Previews in this case? I heard somewhere that it might make the Develop module a little quicker, but is this only when using the Smart Preview and not the full res image?

Lr uses smart previews instead of ACR cache for initial develop-module view when photos are online - amount of benefit is, in my experience, very minor (not noticeable without using a stop-watch..).
But if photos are offline, you may experience more substantial savings.
Note: smart previews are reduced resolution - smart previews of raw files are 2560 x (say) 1920, so if your original raws were say 5120 x 3840, then you/Lr are dealing with 1/4 the number of pixels when editing via smart previews.
Anyway, if you are willing to give up zoom for one edit pass, you can resize the smart previews so 1:1 fits in your allotted display space (e.g. 1280 x 960, which would be 1/8 number of pixels..), e.g. using the PreviewExporter plugin - then things may be significantly faster in develop module. PreviewExporter also has a feature to take originals offline, and put them back online.
To be clear: the amount of savings may or may not be dramatic - how much there is depends on your system, size of raw vs. smart preview image, number and type of edits applied, etc..
Why don't you try it and tell us what you think?!
Cheers,
Rob

Error in setting up current benefit area

Hi Gurus,
I am doing configuration in Benefits administration. As the first step I defined benefit area, and then assigned to the currency. I was trying to get into Set current Benefit area node but it says no value found and it does not allow me to get inside the table itself.
Can someone tell me what has to be done. I am stuck in the initial stage itself and not able to proceed further.
Thanks and regards
Sunitha

Hi,
I am asking about how to set current bebefit area. I have already configured under BAREA, Can you please check that node and tell why I am getting that error.
Thanks and Regards

Benefit Cost entry

Hi Guys
wondering is anybody has used tools like LSMW or CATT to upload benefit cost values in V_5UBI_A. my LSMW gives error messages. Remember, this table is different from other PAnnnn tables where LSMW works like a charm. we are using the following fields:
V_5UBI_A-BPLAN ( benefit Plans)
V_5UBI_A-BCOST (Cost Rule Variant)
V_5UBI_A-CSTV1 (Cost Grouping)
Since same Benefit plan has multiple benefit cost variant and under one single cost variant has multiple cost groupings, LSMW give error that field 'BPLAN' has entry in there.
That's why I say this table is different from any other PAnnnn tables where I have used LSMW dozen times.
Please let me know if anybody has ever used any or the tools to upload benefit cost value in V_5UBI_A. Use of any 3rd party tool is out of question.
Appreciate your help.
Thanks
