Need Advice IO and performance

Dear DBA's
I have objects which is having 10 partiotions which is day wise, each day it loads the data on corresponding date object, each partiotion i assigned each tablespace.
in this objects it loads 6 to 7 million records each day.
example :
CREATE TABLE TEST (<COL. NAMES>)
PARTITION( PARTITION T1 <CONDITION> TABLESPACE T1_TBS,
PARTITION T2 <CONDITION> TABLESPACE T2 TBS,
PARTITION T3 <CONDITION> TABLESPACE T3_TBS,
PARTITION T4 <CONDITION> TABLESPACE T4_TBS,
PARTITION T5 <CONDITION> TABLESPACE T5_TBS,
My plan to change the above structure for that i need your advice.
In above structure each object is taking 10 tablespaces.
If i make it one tablespace instead of 10 tablespaces, is there any impact on IO or performance of the database?
Regards,
SG

Which pizza has fewer calories; pizza uncut (1 peice) or pizza cut into 10 pieces?
How does number of tablespaces change the amount of I/O operations to read whole table?

Note
   - SQL profile "SYS_SQLPROF_014f902e2ea4c002" used for this statement

some comments:
it would be more simple to read the plan with indentatitions: you could use a fixed-width font
it's hard to tell much about the plan without seeing the corresponding query (though in this case the predicate section gives some information on the query - especially step 1)
the plan shows the use of a sql profile: so the CBO uses additional statistics to generate the plan
in step 3 there is an index skip scan: that's only a good idea if there are few distinct values for the leading column of the index and the selectivity of "TICKET_REFERENCE_1" IS NULL is good
in step 6 there is a Full Table Scan for the driving table of a nested loops join: the cost value for the scan is very small and so is the cost for the complete NL join - and that could be misleading
I would use the gather_plan_statistics hint to get a plan with rowsource statistics to check if the cardinalities the CBO works with are correct. If they are not you could try to disable the profile (or create a new profile; of course after checking who created the profile and for what reasons). With an accurate sql profile the CBO should have enough information to create an accurate plan in most cases.

I need to sort very large Excel files and perform other operations. How much faster would this be on a MacPro rather than my MacBook Pro i7, 2.6, 15R?

I am a scientist and run my own business. Money is tight. I have some very large Excel files (~200MB) that I need to sort and perform logic operations on. I currently use a MacBookPro (i7 core, 2.6GHz, 16GB 1600 MHz DDR3) and I am thinking about buying a multicore MacPro. Some of the operations take half an hour to perform. How much faster should I expect these operations to happen on a new MacPro? Is there a significant speed advantage in the 6 core vs 4 core? Practically speaking, what are the features I should look at and what is the speed bump I should expect if I go to 32GB or 64GB? Related to this I am using a 32 bit version of Excel. Is there a 64 bit spreadsheet that I can us on a Mac that has no limit on column and row size?

Grant Bennet-Alder,
It’s funny you mentioned using Activity Monitor. I use it all the time to watch when a computation cycle is finished so I can avoid a crash. I keep it up in the corner of my screen while I respond to email or work on a grant. Typically the %CPU will hang at ~100% (sometimes even saying the application is not responding in red) but will almost always complete the cycle if I let it go for 30 minutes or so. As long as I leave Excel alone while it is working it will not crash. I had not thought of using the Activity Monitor as you suggested. Also I did not realize using a 32 bit application limited me to 4GB of memory for each application. That is clearly a problem for this kind of work. Is there any work around for this? It seems like a 64-bit spreadsheet would help. I would love to use the new 64 bit Numbers but the current version limits the number of rows and columns. I tried it out on my MacBook Pro but my files don’t fit.
The hatter,
This may be the solution for me. I’m OK with assembling the unit you described (I’ve even etched my own boards) but feel very bad about needing to step away from Apple products. When I started computing this was the sort of thing computers were designed to do. Is there any native 64-bit spreadsheet that allows unlimited rows/columns, which will run on an Apple? Excel is only 64-bit on their machines.
Many thanks to both of you for your quick and on point answers!

I'm desperately needing advice to a common question. I use Quicken and love it. But the Mac version is not as great as the PC.   Has anyone installed it by segmenting their Mac with Parallels or Fusion or Boot camp. If so, which one do you recommend.

I'm desperately needing advice. New Mac.   Used Quicken on my PC. Researched all software for Financial programs and Quicken is still the most recommended.   I want to use Quicken on my Mac. The Mac version is not highly rated so I would need to partition my Mac.   Has anyone done this for their quicken program and if so, which partitioning program did you use - Parallels, Fusion ware or Boot camp?
Thx

Virtual Box is safe and well developed, it offers similar or identical features to the paid competition, it may be a little less polished but that's all.
Download and try it out, nothing to lose (except time).

New user of G4 - need advice on selection of printer, DV and digital camera

I am a recent convert to mac and need advice from experts on the following:
I plan to use my G4 MDD primarily for home computing, experimenting with digital photography, create DVDs and explore multimedia primarily as a hobby. Please advice me on selection of a decent digital camera and or a DV camera. I am not sure if I have a decent DV camera - whether this will be good enough for still photos as well. My G4 has firewire ports.
Also I am interested in buying a printer that I can use with my mac as well as connect to a two other windows systems. My printing needs are primarily documents and maybe photos.. I think that going in for a laser printer makes sense in terms of reliability .
I am not looking for the highend equipment - willing to spend upto 750 $ on all items. Thanks in advance.

raja,
welcome to discussions.
Digital Camera, DV camera and colour Laser Printer all for $750 ??
I'm afraid you'll have to go for an inkjet printer if you want colour photos. Expensive doesn't even begin to describe Colour Laser Printers. HP make good printers, but tend to be a bit more expensive to run, Epson make excellent photo printers, are are a bit more economical to run, take a look at the iP4000 and iP5000. I still use my old HP DeskJet 1200 (does A3), and a DeskJet 970Cxi (everyday), both use the same cartidges. These are about 7 years old, there are modern versions retailing now at about half of what I paid for these then(always the case).
Digital cameras can be decided by what purpose you intend to use them for. I have an 18 month old Nikon D100 digital SLR. 6M pixel (which was a lot then) but that might not matter, it takes Nikon lenses (and other manufacturer lenses to the same spec), so I can shoot with a 300mm, 400mm, 600mm lens. Nikon has a D50 out now, a cheaper, newer version of my camera. I can print A3 photo real from 6M pixels and with the right lens I don't need to crop my pictures too much. If you want to print photo real A4 (and that's a LOT of ink) a 3-4M pixel camera would be fine. Most cameras now are 5-8 M pixel, this is because the pictures they take have to be cropped drastically because they have an inadequate lens. On top of that my Nikon takes really great pictures, better than any of my other digi cameras (but not as good as my ancient Olympus 35mm muji-zoom compact with 200 film).
So if you're going to take a lot of close ups in well lit areas, product shots, interior shots with flash, ie. "snaps" rather than photography, any cheap digi camera will do. Good points are
- USB / Firewire connectivity,
- non-proprietry battery technology, ie. it uses 4 x recharable AAs instead of a battery that only fits that camera, and it comes with a AA recharger.
- non-proprietry storage technology, ie. it uses Compact Flash or some other that is used by a large portion of cameras, rather than just be that manufacturer.
- digital zoom is worthless.
If you're doing outdoor photography, wildlife, landscapes, etc, you may want something with a changeable lens and SLR technology, a digital SLR. Not all digital SLR cameras have changeable lenses. Same good points as above, but be prepared to sacrifice one of the points for a good camera. Heavy cameras are easier to hold steady with a big lens, so try for a metal case (it'll be coated in plastic anyway).
For outdoors the most important thing is the amount of light entering the camera (indoors you can control the lighting with flash / fitted lighting), digital SLRs can have enormous lenses (my 28mm hyperzoom lens has a 72mm diameter), compare this to a compact digital camera with a 12mm diameter lens, I take 36x the light of a compact. And it shows in the picture quality.
I'm a complete duffer with DV cameras so I won't lead you astray with this, but be aware some do offer the option to take digital pictures. Indeed some digital cameras can take low quality short movies.
Let us know if you have any more questions.

PC and Home Theatre Hookup....need advice

)PC and Home Theatre Hookup....need adviced Ok, I'll try not to sound so illiterate......
I am in the process of connecting my PC to my home theater setup and have the following:
. The computer has the X-Fi Platinum Fatality card with the I/O Bay
2. The A/V receiver is the Sony STR-DG70...it has the Optical and Coaxial digital inputs and it does have the dts logo
3. Polk Audio 5. speakers connected to receiver
4. The Creative Home Theater Connect DTS-60
Now the questions:
. Could I have just used the Flexijack connection on the card running to receiver digital optical input? I am not using the I/O 3/2" bay that came with the card....don't have an extra bay to install in the new case?
2. Could I have just used the Sound Blaster Digital I/O Module from the Flexijack connection on the card?to receiver digital optical input?
3. Or do I need to use the Creative Home Theater Connect DTS-60? And if so is the Optical connection the best of the two?
Thanks so much for any help,
Kenny

- This will fit your "flexi-jack" when connecting to optical sources........

HT1212 I have shattered my iphone 4s screen and cannot backup all the data through itunes because it is asking me to unlock it. I do not wish to repair the screen as I'd rather buy a new iphone, but I need the photos and contacts. How do I perform a backu

P.S.
I feel as though I am forced into repairing the iphone before I can backup the information (photos, videos, contacts). If the apple ID on the device is the same as the one on my iMac I do not understand why I have to unlock the iphone by typing in the 4 digit passcode. This is a little ******** as having the screen break seems to be the usual prpblem with the iphone, I want to be able to backup my files when I feel the obvious need to do so (eg. when it breaks)! I also believe I shouldn't have to use other apps for backing it up (which I obviously have to pay for).. I am rather angry with this issue.

Okay folkes, you were right and I was wrong.. I admit it. But I was pretty mad though when I tryed to backup the last few contacts I needed for work and couldn't do so. Worst things are when something gets broken (by me or whatever) when there is an emergency. I needed the contacts off of that phone real fast and couldn't do it, thats what got me real mad. And btw I am a Russian living in Moscow and instead of having an official Apple store we have shopes called ReStore who resell apple devices with ridiculous prices, same thing with the repairs. It is cheaper to sometimes buy a new iphone then repair an old one.. So there.. but I repaired it and now happy again with my apple device.. Also I know the itunes and icloud are free and I do back it up, this time however I couldn't use them and had to try the iphone extractor app, which is not free. There.. Thanks for the attention every1

Need advice on video download and edit

I need to download and edit video, have not done it before. My Mac is a PowerBook G4 from 2005. The videocamera I have is a Sony GL2 digital which uses a mini DV cassette. I have a cable, a 4-pin DV to 6-pin firewire. What software do I need? (Currently I have only graphics apps, Adobe CS2, Dreamweaver, Flash, Quark.) The type of editing I need to do initially is cut out crap scenes, piece together good scenes, and export mpeg clips. I do not have a DVD writer on this Mac. I love Adobe products but I can't spring for Premiere right now.

iMovie came with the computer. Capture and cut away.
You'll need an external DVD burner if you want to output stuff. iDVD will allow you to burn the video to disk.

Need advice on ORA-01578: ORACLE data block corrupted

We have a development database server version- 10.2.0.3 with materialized views refresh as complete every morning. Yesterday we had a power failure and the server went down and database was shutdown unexpectedly.
When we restarted the database after the server restarted, we found some of the datablocks got corrupted . Following were the exceptions that we saw in the alert.log.
Errors in file /i01_01/app/oracle/product/10.2.0/db_1/admin/orcl9/bdump/orcl9_smon_7547.trc:

where " INVENTORY_TXN " is a materialized view that was using the block that got corrupted. I can always recreate the MV by dropping and recreating it. Will it solve the problem???
If not, how can I recover/repair the block.???
Can anyone advice on this. Thanks very much in advance.

To recover a corrupted block,the best way out is to use Blockrecover command of RMAN. So you would need RmAN backup to perform the operation.But first ypu you need to ensure that this is a persistent error or not? Is this error is coming repeatedly or just once it happened?

Need advice regarding an interview

Hi,
Since everytime I had a confusion, it was resolved by this forum only, so now again I need ur support and advice.
Actually, I'm a struggler seeking desperately for job of a junior/asst. DBA. I've done MCA(Master in Computer Application) and OCA (Oracle Certified Associate) DBA.
Now in the next month I've to take the last exam (Performance Tuning) to be an OCP. Since I m a fresher in this field, I m not getting any job opportunity.
I'd already discussed my problem on this forum and had got lots of precious advices which recharged and motivated me a lot.
Now today I got an interview call from HCL company for the post of an 'asst.programmer' which is not the field I was looking for. But since I m getting an opportunity from a big company I m not able to resist it. Plz advice me of what should I do in such situation.
Further,I m not in practice of the programming languages for a long time so I m not sure whether I'll get through the Interview or not. Plz suggest.The interview is tommorow.

If you've got some knowledge of programming then at least it's a foot in the door and will allow you to gain experience.
Likewise, going for the interview will give you experience of the interviews, even if you don't get the job.
A good programmer has a good understanding of the way a database works, so the DBA skills you've already learnt will help you and, if you get the job, the programming will give you a good idea of how people need to use the database, so that too will support your DBA skills and you can eventually work up to the job opportunity you want.
We all had to start somewhere. ;)

Help:set up simple test sequence, operator selects particular test then teststand links to part of sequence file and performs test

Hi,
I am extremely new to TestStand, please see question below and offer advice.
I want to set up a simple test sequence.
I want a message to popup on screen that asks the operator which unit of 6(max 10) Units to test(i.e. there are say 6-10 box's to select from).
Then the sequence goes to the particular part of the sequence and performs the test on which ever unit was selected.
What is the best way to do this?
Could i use message popups to do this?and if so what do i need to do link it to the correct part of the sequence file?
Do message popups only allow 6 options to select from?
Thanks,
Solved!
Go to Solution.

Hi,
   You can do using message popup method. You can ask the user which unit want to execute by inserting message in message expression in message popup step settings.Something like below
"Enter unit number to execute
1. Unit1
2. Unit 2
10. Unit 10"
then check "Enable response text box" from options tab in step settings.When user enters unit number you can get the user entered value by inserting the below statement in post expression of message popup step settings
    Locals.String = Step.Result.Response
    Note : String is a local variable to be defined.
Convert that string in to number and send that output to switch expression there by you can use a sequence call step to call sequence whichever to be executed. (I hope your each unit will be seperate sequence file)
I hope these resolves your problem. If you don't understand let me know so that I can develop a small example and send it to.
Cheers,
krishna

Need advice to back up an old iPhone 3G

I need some help, and I am hoping for some advice! I want to backup my iPhone 3G, but it's too old to talk with my iTunes anymore. Back in the day, I used to update my phone regularly, until the software became advanced enough that I heard it had started being incompatible with the 3G phones, so at this point it hasn't been updated in a long while and has an old iOS. (I'm not sure exactly which one.) I have, however, regularly updated my iTunes. Now, though, it no longer can access my iPhone, since the phone software is too old. I assume that if I temporarily went back to an older version of iTunes, I could once again connect to my iPhone and perform a backup.
Is this true? And if so, what version of iTunes would be old enough to access a 3G for a backup that I could later move to a newer phone (not sure what yet, as I haven't bought one yet). Alternatively, is there another good way to do this?
I would appreciate any help y'all can provide! Thank you!

"I want to backup my iPhone 3G, but it's too old to talk with my iTunes anymore."
Not so. This does not happen. You can still sync an original iphone to itunes.
Please explain.
The software does not get too old to sync to itunes.

HELP: NEED ADVICE ON HOW TO UPGRADE MBP!

Specs: 13" MBP (Early 2011) 2.3 GHz Core i5, 4GB of RAM, 320GB HDD -- upgrading to new computer is not an option since every component inside is now sautered into the motherboard.
I have a predicament that I REALLY need your advice on. BACK STORY: 1. Planning on upgrading MacBook Pro to SSD - reason: increase speed and performance (currently using traditional HDD) 2. Double RAM to 8GB. 3. For Computer Science courses in college, will possibly need to install Windows 7 OS for Programming.
Choice #1: Clone Mac OS and create a Partition to Install Windows OS on SSD. (basically run 2 OSs on 1 SSD.)
Drawback to choice #1: Not a good idea to write large files to SSD (2 OSs + programs + other docs.) Will potentially kill SSD.
Choice #2: Clone Mac OS to SSD, Wipe the current HDD and Install Windows OS on that. After installation, remove Optical Drive and install HDD (with a caddy) with Windows OS in its place. (basically take out Optical Drive and have 2 Hard Drives inside computer.)
Drawback to Choice #2: When powering on computer, will have 2 HDs running. A. 2 HDs running regardless if I need them or not. B. Will significantly drain more power from computer and potentially kill it.
Choice #3: Install Parallels and run Windows off of that.
Drawback to Choice #3: If Parallels crashes or freezes, Windows will need to start and that is bad for computer.
Any suggestions? Thanks.

Apparently you are committed to certain hardware. There is no question that the SSD should be installed in the current HDD bay. Should you choose to have a second HDD, it should be installed in place of the DVD drive. Note that some early 2011 MBPs had SATAII connections to the DVD drive and some had SATAIII connections (presumably later production models).
I do not run Windows on my MBPs but I do know that parallels is a resource hog. On that basis, I suspect that it should be installed on the SSD where you can take advantage of the faster processing. The SSD will be electrically more efficient than than a HDD. If you have concerns about battery run time, then do not install the HDD in place of the DVD drive. I do not know if there are third party applications that allow user intervention for controlling a HDD in the DVD bay. You might search for same. If there is, then the argument of installing it there becomes a stronger one.
You will have to assess your own work flows to determine what impact it has on the configuration options. Since I do not know them, I cannot comment on that.
Ciao.

Need advice regarding physical standby databases in rac environment on orac

need advice regarding physical standby databases in rac environment on oracle 10G r2
I like to have have a Primary ( 10 node RAC cluster ) shipping to a physical standby ( 3 node RAC cluster ) shipping using LGWR .
So I have a lot of questions
1) What will be the performance overhead on the Primay if we are using LGWR SYNC option .
2) Does the overhead depends on the physical distance between primary & physical
3)Do you recommend a seperate private network for shipping logs between primary and standby.
4) I know that DGMGRL supports RAC only from 10g. So are there any know issues are bugs using DGMGRL is RAC environments.
Thanks in advance
-Satish

Generally you should have same CPU architecture and same operating system but it's not mandatory to have the exactly the same CPU model, the same number of CPU, the same RAM size etc.
Actually starting with 11.1 you don't need to have the same hardware setup: it 's even possible to have primary and standby database on different platforms: http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/standby.htm#i72053.
