How to measure how much "commit implicit group" took place?
Hi all.The BP is 11.2.0.3 on a linux machine.
As far as I know, when multiple sessions lance "commit" at the same TIME, oracle is committed "IMPLICIT group."
instead of making each commit unique.
= > the ' commitments of the user "for each request validation.
How can I measure how much "commit implicit group" occurred?
Is not "lot of explicit validation.

You can not - there is no way to derive an accurate measure of available information.
However, a session which issued a commit (or rollback) go into a wait for "log file sync", and publishes the journal writer "again written ' to copy the log to disk buffer. so as you ignore the errors introduced by the second 3 timeout, or 1 MB, or relaxation space of 1/3 and then the number of expectations on "log file sync" less the value of the statistic of the system "do it again" written should give you a reasonable approximation of the desired result.
Judging by your last two questions, it seems that you could do to get a copy of the core Oracle - the things you ask is pretty well coveredin manuals, but Oracle base is trying to present the mechanisms in a narrative form more that some people find it easier to assimilate.

I can go overboard in creating groups of tabs. I say this because now my system begins to act a bit lazy. I created 7 groups, two of which have 9 or 10 tabs. Should I shoot the number of groups I create (as well as the way in which several tab located within each group). In other words: how much RAM tab groups use. How can I calibrate or understand the trade off between these markers and the amount of RAM they are using?

Should we leave how much free space on the C drive before affecting the performance and speed?
Hello!
Hard drive of my new PC (C) is 1 TB (processor Samsung 7i, Windows 8.1). It doesn't have any other disk/partition. How this space is safe to use to store large files (videos, esp., stored in the native video library file) without harming the performance and speed?
And if I create another partition (D) and just use it for storage, it will make much difference compared to the above?
Thank you!

Planning your Partitions
The Question
Partitions, how much should I have on my hard drive, what do I use
each of them for, and what size should each one be?It s a common question, but unfortunately this doesn t have a
only simple, just answer to all the world. A lot of people will respond with
the way they do, but their response isn't necessarily best for the
person seeking (in many cases it isn't right even for the person)
response).Terminology
First, let's rethinking the terminology. Some people ask "should I".
partition my drive? That s the wrong question, because the
the terminology is a little strange. Some people think that the word
"partition" means divide the drive into two or more partitions.
That s not correct: to partition a drive is to create one or several
partitions on it. You must have at least one partition to use
He who think they have an unpartitioned disk actually
have a player with only one partition on it and it s normally
Called C:. The choice you have is to have more than one
partition, not that it's the partition at all.A bit of history
Back before Windows 95 OEM Service Release 2 (also known as Windows
95 (b) was published in 1996, all MS-DOS and Windows hard drives have been set
using the file system FAT16 (except for very tiny to aid
FAT12). That 16-bit only because were used for addressing, FAT16 has a
maximum 2 GB partition size.More than 2 GB of hard disks were rare at the time, but if you had
one, you must have multiple partitions to use all the available
space. But even if your drive was not larger than 2GB, FAT16 created
Another serious problem for many people - the size of the cluster has been
more great if you had a larger partition. Cluster sizes increased from 512
bytes for a partition to no greater than32Mb all the way up to 32 KB for a
partition of 1 GB or more.More the cluster size, the space more is wasted on a hard drive.
That s as space for all the files is allocated in whole clusters
only. If you have 32 KB clusters, a 1 byte file takes 32 KB, a file, a
greater than 32 k byte takes 64 k and so on. On average, each file
about half of his last group waste.If large partitions create a lot of waste (called "soft"). With a 2 GB
FAT16 drive in a single cluster, if you have 10,000 files, each
lose half a cluster of 32 KB, you lose about 160 MB for relationships. This s
back in an important part of a player that probably cost more than $400
1996 - around $ 32.So what did the people? They divided their 2 GB drive in two,
three or more logical drives. Each of these logical drives has been
smaller the real physical disk, had smaller clusters, and
so less waste. If, for example, she was able to keep all the partitions
less than 512 MB, cluster size was only 8 KB, and the loss was reduced to a
a quarter of what it would be otherwise.People partitioned for other reasons also, but back in the days of
FAT16, it was the main reason to do so.The present
Three things have changed radically since 1996:
1. the FAT32 and NTFS file systems came along, allowing a larger
partitions with smaller clusters and so much less waste. In
with NTFS, cluster sizes are 4 K, regardless of the size of the partition.2 hard drives have become much larger, often more than 1 TB (1000 GB) in
size.3 hard drives have become much cheaper. For example, a 500 GB drive
can be bought today for about $50. That s 250 times the size of this
Player 2Gb typical 1996, about one-eighth of the price.What these things mean together which is the reason to be old to have
multiple partitions to avoid the considerable wastage of disk space left.
The amount of waste is much less than it used to be and the cost of
that waste is much less. For all practical purposes, almost nobody does
should no longer be concerned about slack, and it should no longer be
has examined when planning your partition structure.What Partitions are used for today
There are a variety of different ways people put in place several
scores of these days. Some of these uses are reasonable, some are
debatable, some are downright bad. I'll discuss a number of Commons
partition types in the following:1. a partition for Windows only
Most of the people who create such a partition are because they believe
If they never have to reinstall Windows properly, at least they
He won t lose their data and he won t have to reinstall their applications.
because both are safe on other partitions.The first of these thoughts is a false comfort and the second
is downright bad. See the analysis of the types of partition 2 and 4
below to find out why.Also note that over the years, a lot of people who find their windows
partition that has begun to be the right size proves to be too
small. For example, if you have such a partition for Windows and later
upgrade to a newer version of Windows, you may find that your Windows
partition is too small.2. a partition for installed programs
This normally goes hand in hand with the partition type 1, a partition for
just Windows. The thought that if you reinstall Windows, your
installed application programs are safe if they are in another
partitions is simply not true. That s because all programs installed
(with the exception of an occasional trivial) have pointers to the inside
Windows, in the registry and elsewhere, as well as associated files
buried in the Windows folder. So if Windows, pointers and
the files go with it. Given that the programs need to be reinstalled if Windows
the fact, this reasoning to a separate partition for programs not
work. In fact, there is almost never a good reason to separate
Windows of the software application into separate partitions.3. a partition for the pagefile.
Some people think mistakenly that the pagefile on another
score will improve performance. It is also false; It doesn t
help and often I hurt, performance, because it increases the movement of the head
to get back to the page to another file frequently used
data on the disk. For best performance, the paging file should normally
be on the most widely used score of less used physical player. For
almost everyone with a single physical disk than the same drive s
Windows is on C:.4. a partition for backup for other partitions.
Some people make a separate partition to store backups of their other
or partitions. People who rely on a "backup" are a joke
themselves. It is only very slightly better than no backup at all.
because it leaves you likely to be simultaneously the original losses
and backup for many of the most common dangers: the head crashes and other
types of drive, serious glitches to power failure, near lightning
strikes, virus attack, even stolen computer. In my opinion,.
secure backup must be on a media removable and not stored in the
computer.5. a partition for data files
Above, when I discussed separate Windows on a clean partition,
I pointed out that separate data from Windows is a false comfort if
He of done with the idea that data will be safe if Windows ever
must be reinstalled. I call it a false comfort that's because
I'm afraid many people will rely on this separation, think that their
data are safe there and so do not take measures to
Back it up. In truth the data is not safe there. Having to reinstall
Windows is just one of the dangers to someone a s hard disk and not
probably even one. This kind of "backup" falls into the same
category, as a backup to other partitions partition; It lets you
sensitive to the simultaneous loss of the original and the backup on many of
the most common dangers that affect the entire physical disk, not
just the particular partition. Security comes from a solid backup
diet, not how partition you.However, for some people, it may be a good idea to separate Windows and
programs on the one hand of the data on the other, putting each of the
two types into separate partitions. I think that most people
partitioning scheme must be based on their backup system and backup
plans are generally of two types: whole hard disk imaging
or data only backup. If you back up data, backup is
usually facilitated by the presence of a separate with data only partition;
to save just the score easily, without having to
collect pieces from here and elsewhere. However, for
those who backup by creating an image of the entire disk, there is
usually little, if any, benefit the separation of data in a partition of
its own.Furthermore, in all honesty, I must point out that there are many
very respected people who recommend a separate partition for Windows,
Whatever your backup plan. Their arguments haven t convinced
me, but there are clearly two views different here.6. a partition to image files
Some people like to deal with the images and videos as something separate
other data files and create a separate partition for them. To my
the spirit, an image is simply another type of data and there is no
the advantage in doing so.7. a partition for music files.
The comments above related to the image files also apply to music
files. They are just another type of data and must be dealt with the
just like the other data.8. a partition for a second operating system to dual-boot to.
For those who manage several operating systems (Windows Vista, Windows
XP, Windows 98, Linux, etc.), a separate partition for each operating
system is essential. The problems here are beyond the scope of this
discussion, but simply to note that I have no objection to s
all these partitionsPerformance
Some people have several partitions because they believe that it
somehow improves performance. That s not correct. The effect is
probably low on modern computers with modern hard disks, but if
whatever it is, the opposite is true: more music mean poorer
performance. That's because normally no partition is full and it
so are gaps between them. It takes time for the drive s
read/write heads to cross these gaps. Close all files
are, faster access to them will be.Organization
I think a lot of people overpartition because they use scores as a
organizational structure. They have a keen sense of order and you want to
to separate the apples from the oranges on their readers.Yes, separating the different types of files on partitions is a
technical organization, but then is to separate different types of
files in folders. The difference is that the walls are static and
fixed in size, while the files are dynamic, changing size automatically
as needed to meet your changing needs. This usually done records
a much better way to organize, in my opinion.Certainly, partitions can be resized when necessary, but except with the latter
versions of Windows, which requires a third-party software (the and the
possibility to do so in Windows is primitive compared to the third-party
solutions). These third party software normally costs money and not
any point and how stable it is, affects the entire disk.
with the risk of losing everything. Plan your partitions in
first place and repartitioning, none will be necessary. The need
to repartition usually occurs as a result of overpartitioning in
the first place.What often happens when people organize with partitions instead
records are that they make a miscalculation of how much room they need on each
This partition, and then when they run out of space on the partition
When a file is logically, while having plenty of space
on the other hand, they simply saving the file in the score of "poor".
Paradoxically, therefore, results in this kind of score structure
less organization rather than more.So how should I partition my drive
If you read what came before, my findings will not come as a
surprise:1. If your backup set is the image of the entire disk, have just one
single (usually c partition :));2. If you backups just data, have two partitions one for Windows and
application programs installed (usually c :)), the other for data
(normally D :).)With the exception of multiple operating systems, it is rarely
any advantage to have more than two partitions. -

How much battery is used while you sleep?
Laptop Toshiba, Win7.
Unofficial tests on a Lenovo ThinkPad T61p (Windows 7) d MacBook
http://Lifehacker.com/5526542/how-much-battery-life-does-sleep-mode-really-drain
FYI - Windows Vista power management
Standby mode consumes battery power, although much less than normal on the State. If the computer is in "sleep" while being powered by the battery and the battery charge runs out, the computer turns completely off and lose the open programs and documents in memory. In this case, any changes to documents which were not yet recorded on the disc would be lost.
Hybrid sleep provides an extra measure of convenience. If the battery of the computer becomes completely discharged when the computer is in hybrid sleep mode, the state saved in the computer's memory will be lost, but Windows will be able to recover the state saved from HDD - although a little more slowly.

Host SSD cache - how much required
recently installed ESXi (free) to use domestic test/study. ESXi starts on the USB.
I have 2 SSD for storage, a 1 to for VMS and a 64 GB for the cache host.
How does the host cache requires? I ask because I would like to use a part of the disk cache host to a dir on it to store ISOs of the OS I want to install on the 1 TB drive and test.
ESXi host does not host any-cache. The power of virtual machines. How many? Depends on how much you commit too host-RAM. If you do not commit too much RAM, you need not the host cache. And if you book all the vRAM to virtual machines, you do not have same virtual machine swap file (with vRAM booking 100% it will not be created).
In the worst case (when commit you too much RAM, no work of sharing/compression/balooning and all virtual machines all use the vRAM you assigned to them) you may need to host-cache of size SSD:
'summary_of_vRAM_assigned_to_all_VMs' - 'host_RAM_available_for_VMs '.
But if your host-cache SSD is smaller, it will be used anyway. And when it is full, 'normal' permutation will be used (with VM paging files).

Hi all, we have a project to produce a high level specification material for a new oracle linux server that would be a merger of our servers to 5 current all open windows to run Oracle 11203 Windows 2008 r2. All our windows boxes are Intel dual core with 12 cores of each. My question is how measure how much cpu is our current that each oracle database uses to determine the min/processor cores required for new linux box? Hope I'm making sense. Thank you!
946212, forget the AWR. What you want to do is to collect statistics from Windows performance monitor to see what percentage of the CPU is used on average and maximum on each machine. Sum of the values to have any idea how much cpu your new server will need. You should probably do the same thing for IO.

How much free space will be left after you import?
Hallo. I need to replace all the patterns on the integration server using those on the production server. I want to know how much free space is left on/off data to the integration server after this kind of refreshment. The two databases are Oracle 9 so I'll use exp/IMP. Here's how I do it. Could check you if I think that good? It is 72 GB of free space on/data on the target server.
Size used Avail capacity mounted file system
/ dev/vgsmxdata/lvsmxcopy G 194,74 122,56 72,18 G G 63% / data
Overall size of the exported schemas of the SOURCE_DB is 150 GB. The same patterns on TARGET_DB takes 90 GB. If the difference is 60GB. Free space in the data files in TARGET_DB is 30 GB. This means that in the first place, the free space in the data files is filled and after that datafiles extend? This would mean that a database would extend up to 150 GB and data/free space would be 40 GB after updating. Am I wrong?

Published by: Przemek P on October 9, 2012 10:48There are a few potential pitfalls. First of all, when you import, the definition of the INITIAL segment may be too big, using more place you expect. This can be things like adding many lines, remove them and do not reset the high watermark before an insertion above the upper limit, or sometimes old problems that nobody noticed have stayed or reproduced. Second, if you have tables that have been updated, by using the pctfree in most blocks, then pctfree is honored to import, leaving more room never-to-be-used in blocks.
From my experience, those who do rarely estimate more than 10% to the title, but sometimes previous misadventures are not completely fixed, wasting a lot of space or using excessive space. I spend usually less computing time and time of observation. But then again, I know what to expect of my App YMMV.

Support of cluster consistency created how much cache?
Hello
I'm runing Oracle coherence GE 3.6.1 clustered.
Support of cluster consistency created how much cache? type of cache is a distributed Cache.
Cache of overcrowding affects the performance of the pole?
Thank you!Hello
Your test is probably not very representative of a real system. Have you run this test with just a single JVM? In the real world you could run a cluster of a number of Java virtual machines.
In removeStartWith what you do is iterate over the set of keys to cache and to keep a number of keys - that is going to be fast in a single machine virtual JAVA.
In removeLike you do a query to filter on the cache and consistency builds a new set to match the keys. It's a lot more work and therefore slower.Your two method names are called "removeXXX' althpough, you do not actually remove anything. If you want to delete the corresponding entries or your methods are very effective ways to make the operation you are trying. With a good group, average the most effective to remove all entries that are preceded by a given string would be something like this...
Filter filter = new LikeFilter(new KeyExtractor(), regex + "%", (char)0, false); nc.invokeAll(filter, new ConditionalRemove(AlwaysFilter.INSTANCE));
In the above code, the delete operation will happen on the cluster and will be distributed across all nodes in the cluster at the same time will be faster that bringing so everything they touch back and remove them one at a time as you do.
In a true cluster works on the cluster where data is usually much more efficient and faster. If you do performance test there is no point in an environment that is not representative of a real-world deployment.

How much slowing down video of slow mo?
Hey everybody,
I'm trying to understand the function of slow-mo of the iPad 2 a little better.
I see that he shoots at 120FPS from the apple site:

Anyone know what rate it plays back videos in? I'm figuring how much it slows the video so if you know that, it would also be useful.
Thank you

The user guide. Normal is 30 images/s, slo - mo is 120 FPS so I would say it's the quarter speed.
"Shoot video.
With camera, you can record videos, including videos of idle and accelerated.
Record a video. Select the video, and then press the save or press a volume button, to start and stop recording. You can choose to capture 720 p or 1080 p at 30 fps (frames will Flash). You can also capture 1080 p at 60 frames per second and 4K video at 30 frames per second video on iPad Pro (9.7 inches). To change the settings for video recording, go to settings > camera & photo > video recording.
Take it slow. (Pro, iPad 2 Air, mini iPad iPad 4) Choose the Slo - mo to capture video of idle at 120 frames per second. Later, when you change the video, you can simply set a part of it to read at idle, and the rest reads at normal speed.

My experience with the original watch is that the heartbeat was working fine with apps in the House but does not work well with third-party applications. Aboriginal health applications were sub par at best. In addition, he wouldn't these third party apps (Strava), unless you were related to your phone. A new doesn't do me much good if it is always the case. Finally, it's great that you can bind your helmet now but what storage is the watch have? I am not unrealistic, its understandable if its not much, but I hope that it is enough that a few apps and music enough to pass through a 4 hour tour.
1 WatchOS3 made major changes in this area, and 3rd party applications get access to things like HR. OS3 also makes everything much more receptive. 3rd party applications will need to be updated to play with the HR monitor.
2. you can run applications 3rd party without the phone with you, but for your type of application, you'll want a series 2 with GPS watch. The likes of Runkeeper OK working in the older shows, but without GPS, they do not really work you need. New - 3rd third party apps will need updates to work with the GPS watch. OS3 software has been available to developers for a while now, so I expect software updates only very quickly. I don't know if or when 3rd parties had access to the equipment and GPS devices, s, then it may be some while before they have series 2 updates.
3. you can store 2 GB of music. How much music that is depends of course format and quality, but certainly several hours.
Hope that helps
