Execute to Parse % is very low!!..need assistance

HI,
While looking in the statspack report, I found that under Instance efficiency area
the percentage for 'Execute to parse' is 10.35% and rest of the percentage are as following:
Buffer Nowait %: 99.89 Redo NoWait %: 100.00
Buffer Hit %: 92.57 In-memory Sort %: 99.98
Library Hit %: 99.86 Soft Parse %: 99.74
Execute to Parse %: 10.35 Latch Hit %: 99.88
Parse CPU to Parse Elapsd %: 81.74 % Non-Parse CPU: 96.19
12040171 parses (31500 hard parses), 13430267 executions
As per me, it is due to the high number of parsing compares to execution. Could anyone tell me that having a percentage for 'Exection to Parse" as above is considered ok? Is there any standard percentage for this parameter that a database should achieve?
Thanks
Ratheesh

I am not sure lack of binding is the problem here
Library Hit %: 99.86 Soft Parse %: 99.74
Execute to Parse %: 10.35 Latch Hit %: 99.88
12040171 parses (31500 hard parses), 13430267 executionsLibrary hit is 99.86 which shows the SQL is being shared and reused, hard parses that you would get if binds are not being used is low, soft parse however is high.
Could be just ref cursor usage

http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:865497961356
Or an application is forcing a parse
http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:4032595293314
Whatever the reason, it means you should leave cursor_sharing set to exact, as it will not positively affect the parse ratio, but can still have all the drawbacks already mentioned.

What is the desired percentage for this ?Depends a lot on your database usage. For an OLTP database, this should be generally speaking much higher. For a datawarehouse, it is less important.
But what really matters is the general database performance evaluated by its users: it is OK or slow or very slow ?
See http://asktom.oracle.com/pls/ask/f?p=4950:8:2765691383260886028::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:4032595293314 to see what you can get and what you cannot get with these numbers.

Low Execute to Parse % and high soft parse %

Hello Folks
I am working on oracle 10g release2 on HP-UX
After going through awr reports observed it have low Execute to Parse % but high soft parse % (Instance Efficiency Percentages)
so cannot say issue with less use of bind variables,then what is cause of Execute to Parse %
searched sites like ask.tom,burselon counsulting etc as usual they had given generic/diplomatic(escaping) replies on this
like due to problem in application code,ineffecient sharing ,due to problem in database parameters etc
without any clear indication for cause and solution like if some database parameters not set properly then should say which database parameters can be checked,cause due to more parsing and less execution
please share if you had faced such issue and any suggestions to solve this
examples why this could happen ,like possibilities in application code
Thanks

Volume on iphone is very low, this is a common problem, Apple Needs to FIX!

I have a new iphone 3GS that I got at the end of July, 2009. Since then i've been having problems with the volume! I called support because i had this problem along with my screen turning blank and freezing up. Support said to take the case off and this might help. well it did help the screen issue (which is kind of dumb when you think about it because the case is supposed to protect the phone and instead it caused it to malfunction!!,wierd), but the volume issue never really changed. I am hearing impaired and I do wear hearing aids, BUT....I have ALWAYS been able to use cell phones that have good loud volume, as i need to remove my aids to use the phone. My LG phone had BEAUTIFUL volume, never had a problem!
So, then I started to do some research and saw this is a very common problem! everyone I know that has an iphone has this problem, and all these people are normal hearing people! So then i decided to just get some really good, superduper headphones, because the headphones that came with the phone were ok, but i had to hold them in my ears.
The other day i bought the new Bose in-ear headphones with superior sound quality and at $130 bucks, they better be and the are compatable with the iphone. But.....again, while actually talking to someone on the phone the sound, even with the headphones and all volumes max'd, was still very low!! and i know its not the headphones because listening to the ipod is fantastic! it must be the phone!!!
I even used the "accessibility" setting that is on the phone and selected the mono audio feature which pushes both L&R sounds through one channel, and still doesnt help!
I even called support back today and one guy said i had to "restore" my phone by plugging it into my computer (not really sure what he means) but we got disconnected and the other guy said that i should bring my phone into the apple store. Both tech guys denied that there are lots of calls or complaints about this....but as you all know from reading the many posts, that this is a very common problem!!!
I think Apple should do the right thing and recall these phones or at least fix them or SOMETHING!!!! this volume issue is internally, because when i make a call and an automated voice comes on, it works fine (majority of the time) but as soon as a live voice comes on the phone, the volume drops! there must be some type of automatic voice adjuster that is just not working properly. I mean i love my phone!!! But....i cant use it!!! And now, im going to have to return my Bose headphones and try to find something else.
Can anyone really help me?????

I agree with you about the volume on the phone itself. (I have 3Gs). It needs to be louder. I also wear hearing aids. However I do think there may be something wrong with your phone because when I connect my earbuds (Klipsh) I get very good volume through them. In fact at full volume it's way too loud. I would push for a replacement phone.
FWIW, my daughter (who also wears hearing aids) has trouble hearing her iphone. It appears to have more to do with the speaker not being lined up with the hearing aid's input. Her audiologist pointed out that some current hearing aids support bluetooth, I think we will get those next time we replace her hearing aids.

How come my macbook air has so little space. I deleted everything that I don't need and everything that has the most space I'm told NOT to delete. Everything I find is in either KB or very low MB.

What is "Other" and What Can I Do About It?

Your Solid State Drive and having enough space inside your Macbook Air & Pro
Solid State Drive usage premise, or the “more space / upgrade SSD” question
There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
A Professional Example
In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.
You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Slim USB3 1TB external hard drive
External Hard Drives
External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
1. Data backup and protection.
2. Redundancy for important data.
3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

Hi. I Have a Pavilion dv9000 which has always had very low volume - really needs to be increased?

Hi. I Have a Pavilion dv9000 with Vista Ultimate 64. It has always had very low volume and I find I generally have to have the volume up into the 70's 80's as well as the onscreen media player slider almost full - which then gets all distorted - and then have to turn it down again when not using the player as the computer error beeps come screaming out., Ive checked the settings on speakers to make sure all are the same & balanced and also have updated any codecs as needed. Is there a sound lever setting elsewhere?
cheers

Thanks for the reply and peeling my post off Mike, sorry I didn't start my own initially.
Well @ 1333Mhz I was using the rated timings 9-9-9-24 (as per Corsair) but it wasn't very stable as I said.
I have since changed the FSB/RAM ratio to get 1066Mhz and it seemed much happier. (@1.5v) It would be nice to run the RAM at it's rated setting but my OC skills aren't that extensive. I imagine it would need alot of tweeking? Or could I have just relaxed the timings a bit?
Would removing the Switch Cards make any difference?
Thanks in advance.

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Look though other Apple Mail folders like the junk mail and delete the mail that is in there. Look through your sent items folders and see there is any mail in there that can be deieted.
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Low Levels Assistance Please

Hi Guys
I need some help with my new set up
Mac G5 version 10.3.9
Logic Pro 7
Audio Interface = motu 828
I don't understand why I am not getting decent levels through logic audio and maybe someone who knows my set up can assist as I am sure it is easy solution
When i record using a mic into logic via the Motu I get the leds lighting up nicely through the MOTU and also the software interface. But In the logic Audio trackmixer the signal is coming through very low and I have to normalize the file every time.
I am assuming that i need to set up the levels through logic? As even when I peak the trim knobs on the MOtu and get feedback I still dont get a signal through a decent volume through logic
Any ideas?
Thanks in anticipation Carlo

The level meters in logic are peak meters (0dbfs), not rms meters. I would check your interface and make sure you have it setup correctly.
Is it a MKI or MKII 828 interface? How are you connecting your mic to it? A little more info might help solve your problem.

Profire 2626 rear inputs VERY low levels

Several months ago purchased a MACBook Pro + Profire 2626 Audio interface to complete my digital home recording project. Initially spent my spare time getting familiar with the setup & made some attempts to record a basic track, with NO success.
Now I've got a bit more time & started to really focus on recording my first project, ALL attempts to far...No success.
The primary root of my problem is the rear Audio recording levels...are very LOW, on a scale of 10, levels = .5, I've turned up all levels on the audio interface + mixer dials. Routing Analog 1/2 = 7/8. 2 x Front input levels seems fine.
I'm a musisician + fairly computer savvy, recording is new to me. however, this has totally mistified me. Reviewed several forum posting but did not see any obvious solution.
Several forum posting's point to the Profire 2626 Audio interface. I'm confident a savvy & experineced recording artist has a solution. Any assistance would be gretaly appreciated..
Components spec's:
MACBook Pro
- 2.66ghz
- 4GB RAm
- OS= 10.6.8
Logic Express 9
-9.1.5 (1700.9) 32bit
M-Audio Profire 2626
-Firmware: 1.0.10
-Software: 2.3.1.

Hi.
I have had input level problems ever since I bought my iO 26 interface too with Logic Express 9. Here are 2 things I do which might help you. In Inserts go to EQ, Channel-EQ has a Master Gain on the left. I raise it to what I need. Another way I do it is to pull up Gain in Utility and raise the volume there. There might be a better way to do it but I have not found it. I hope this helps.

My call having very low volume to the caller

my call having very low volume to the lisner or caller . how to increase form my iphone.

Hey there pawan922,
It sounds like you are being told that your voice is not clear but they sound fine to you. I would use the troubleshooting in the following article to help resolve the issue here, named:
iPhone: Microphone issues
http://support.apple.com/kb/ts5183
Follow these steps, testing after each.
Make sure nothing is plugged in to the jack connector.
Make sure nothing is blocking any of the microphones (refer to the pictures below to find your device's microphones). Check for these:
Dirt or debris
A screen protector or case
When you're holding your phone next to your ear, make sure you don't block the microphone with your fingers or shoulder and make sure to speak into the microphone
Turn the iPhone off and then on.
Update to the latest version of iOS.
If necessary, find general iPhone hardware troubleshooting suggestions.
For further assistance, contact Apple Support.
If the issue persists and you need to make a call, try using headphones with an integrated microphone.

Execute to parse ratio is 49 any problem

Hi ,
execute to parse ratio is 49 any problem ?

I assume you're looking at a Statspack or AWR report?
First, it's important to understand what the Parse to Execute ratio is.
It's calculated as:
round(100*(1-:prse/:exe),2)So, the idea is, for a given SQL statement, in the ideal world, you parse it once, and execute it many times. If you do that, your Parse to Execute ratio will tend towards 100%. 100% is a "perfect score".
As you parse more and more, relative to executions, the ratio will fall. If you parse once per execution, your Parse to Execute ratio will go to 0%. That's not good, but, it could actually be even worse than that. Some brain dead applications actually do more parses than executions. If that happens, your Parse to Execute ratio will go negative.
So, is 49 "bad"? What is bad? Well, that depends. While it's true that any Parse to Execute ratio that's less than the high 90s could potentially be improved, the question really is how much will that benefit your system?
So, you need to ask yourself some questions. First, do you even have a performance probem? If not, then any effort spent tuning the system is almost certainly a waste of time. If you do have a performance problem, you should be profiling the critical business processes, to analyze and understand where they are spending their time. If one or more, poor performing, critical business processes is spending excessive time on parsing, then it may be worth looking at what's going on.
In general, ratios such as Parse to Execute, buffer cache hit, etc, are almost never useful in isolation. However, if all you have is an AWR or Statspack report, and you're trying to understand if the Parse to Execute ratio needs attention, then you should look at a few other numbers in the report. Look at the Top 5 Timed events; do any of them have anything to do with parsing? If not, then parsing is probably not an issue. Look at % Non-Parse CPU; if it's very high, say in the 90s, then almost certainly parsing is not a significant issue, so who cares about the Parse to Execute ratio?
Finally, if you do think that, in your case, Parse to Execute ratio is a problem, it's important to know that the only way to improve it is by reducing the number of parses or increase the numbers of executions. And, the only way to change number of parses or number of executions, is by changing the client program. There is no instance level adjustment or parameter that will have any effect on that statistic.
Hope that helps you understand how to interpret that statistic,
-Mark

Please suggest what should be the method to troubleshoot this and if I need to check some more information

Well, of course, you probably can't eliminate this sort of thing entirely: a setup such as yours is inevitably a compromise. What you can do is make sure your log buffer is a good size (say 10MB or so); that your redo logs are large (at least 100MB each, and preferably large enough to hold one hour or so of redo produced at the busiest time for your database without filling up); and finally set ARCHIVE_LAG_TARGET to something like 1800 seconds or more to ensure a regular, routine, predictable log switch.
It won't cure every ill, but that sort of setup often means the redo subsystem ceases to be a regular driver of foreground waits.

My ipod 60gb classic is showing as fully charged until I connect it to my pc when it comes up with the error message, 'please wait very low battery' and the little wheel goes round and nothing happens, can anyone explain why this is and what i can do?

I have worked my way through the assistant and nothing works. I have tried connecting in disc mode but although the screen on the ipod is showing that the device is charged and that it is in disc mode as soon as I connect it to the computer it comes up with the error message 'please wait very low battery' and stays like that until I disconnect when it appears to be OK again. I have tried on both pc and mac.
BTW the ipod is an ipod video not classic if that makes any difference.
Thanks

Could Very Low Disk Space Cause problems?

Hi, my 600 GB Hard Drive only had around 5 GB of space left . I purchased a new 1 TB Hard Drive in order to delete media so that I could gain the space back. I've since gained back 200 GB of Space but Could very low disk space cause issues? What kind of issues could occur? Thanks

There are any number of reasons for occasional beachballs to appear. They will appear when some programs are involved in heavy disk I/O which tends to be processor dependent and causes the program to suspend all other activity until the disk activity has completed. This is more often the case when writing to the disk. Beachballs may also appear if the OS has to use disk I/O and is slowed down by an over-filled and/or fragmented hard drive. The fuller a drive gets the greater the likelihood that fragmentation will become a more noticeable problem. Beachballs can appear if you are low on physical memory so applications must resort to disk-based virtual memory which is considerably slower and tends to cause the computer to become slow or unresponsive for a period of time. It can also cause disk-thrashing. Beachballs can occur if the disk has become corrupted causing applications to have difficulty reading from or writing to the disk.
It is possible to repair a drive's directory, and it's even possible to identify corrupted files, but it's not possible to repair corrupted files nor repair a corrupted drive. If a drive develops corrupted files either the files will need to be replaced or deleted. If a drive develops soft sector errors these can be repaired by erasing the drive (reformatting.) If a drive develops hard sector errors these may or may not be repairable, but if they are repairable it requires zeroing the data during a disk formatting operation. If the disk directory becomes corrupted that can be repaired using Disk Utility or one of the various third-party utilities such as Disk Warrior. Disk Utility can repair many but not all directory corruption problems. What DU cannot fix Disk Warrior usually can.
You can start repairing a drive as follows;
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
This applies to your startup volume. No need to repair permissions on any but a startup volume.

Execute to Parse % is very low!!..need assistance
