Poor NAS reading performance in OS X - need help

Ok, this one is a mystery to me and it's driving me nuts.
I have the following computers on my gigabit network:
- iMac (Mid 2010) 27" i7 (Dual Boot configuration, Win7)
- iMac (Early 2006) 20" Core Duo
- MacBook (Mid 2007)
- Dell XPS M1710 Gaming Laptop running Win7
The NAS in question is a DROBO FS equipped with three 2TB Western Digital drives giving me 3.75TB usable storage.
All computers can see and access the DROBO. All computers can mount and use all the shares.
Both the Dell and iMac under Windows 7 seem to be able to write and read the DROBO at speeds as one would expect. Everything works great.
Read: ~35Mbyte/s
Write: ~25Mbyte/s
Once I access the DROBO in OS X however something seems to be causing problems.
Read: ~2Mbyte/s
Write: ~25Mbyte/s
As you can see, the read performance is way slower than it should be. Additionally, it's not a consistent flow of data. Sometimes it will only push 500kb/s then jump back up to around 2Mbyte/s and so forth. It's as if there is something corrupting it or really working against the flow of data.
Since I have my iTunes library stored on the DROBO it makes it virtually unusable and DROBO tech support so far has been useless.
If anyone has any ideas about what I can try, please let me know since I'm at my wits end.

I'm having the exact same problem the original poster described. Drobo works fine (quickly) for both reading and writing on my Windows 7 PC. I can write quickly from my Mac Mini to the Drobo, but can only get 1-2MB/second read speeds. I too have tried direct-connecting the Drobo to the Mini, and that provided the fast speeds I expected. However, I don't think it's a switch issue, because I have both a D-Link gigabit switch and an Airport Extreme base (wired) between the Windows 7 PC and the Drobo. Additionally, I've tried hooking the Mini and Drobo both up to the Airport Extreme (in case the D-Link switch was doing something strange), but got the same issue.
The Mini has all its software updates, the drobo has both firmware and software updated completely. Any suggestions would be most appreciated, the inability to stream movies is making the Drobo almost useless for me.

Cannot perform Mac OSX recovery need help

Morning forum
I am hoping that I can find the help to my issue here as I need this machine up for business. I m having trouble reinstalling the OS as it is stating that it cannot find the system folder (folder with ?). I have tried to perform recovery installation holding down command R and also the other option of holding X down whilst boot up but it seems the keyboard shortcuts are not working or is there a more serious problem. I tied the RAID sets yesterday and all came back all drives seem to be ok. I am baffled as to what I can do. Any help is always appreciated.
Regards

You have no recovery partition. This is a normal condition if your boot volume is a RAID.
You have several options for reinstalling.
1. If you have access to a local, unencrypted Time Machine backup volume, and if that volume has a backup of a Mac (not necessarily this one) that was running the same major version of OS X and did have a Recovery partition, then you can boot from the Time Machine volume into Recovery by holding down the option key at the startup chime. Encrypted Time Machine volumes are not bootable, nor are network backups.
2. If your Mac shipped with OS X 10.7 or later preinstalled, or if it's one of the computers that can be upgraded to use OS X Internet Recovery, you may be able to netboot from an Apple server by holding down the key combination option-R at the startup chime. Release the keys when you see a spinning globe.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
3. Use Recovery Disk Assistant (RDA) on another Mac running the same major version of OS X as yours to create a bootable USB device. Boot your Mac from the device by holding down the option key at startup.Warning: All existing data on the USB device will be erased when you use RDA.
Once you've booted into Recovery, the OS X Utilities screen will appear. Follow the prompts to reinstall OS X. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
If none of the above choices is open to you, then you'll have to start over from an OS X 10.6.8 installation. There's no need to overwrite your existing boot volume; you can use an external drive. Install 10.6 from the DVD you originally used to upgrade, or that came with the machine. Run Software Update and install all available updates. Log into the App Store with the Apple ID you used to buy 10.7 or later, and download the installer. When you run it, be sure to choose the right drive to install on.

Performance issue in DB need help with analysing this ADDM report

Hi,
My environment:
Os: RHEL5U3 / 11.1.0.7 64 bit / R12.1.1 64 bit
Issue:
Few days are am facing serious of performance problem in our Production instance. Normally the issue will occur 5 to 10 minutes occasionally per day. At the time of issue we not able to access the EBS application its taking time to load. But backend all the oracle, listener and apps services are up and running. No locks at table and session level. Cpu and memory usage is normal.
We have monitored using "Enterprise Manager" for this issue and we found the wait session present more in Active session tab. At this time EBS application is not able access its loading too time. After some time the in Active session tab the wait session came normal and when we try to access the EBS application its working fine.
We try to find the cause of the issue by running addm report. But am not able to understand what its says. Kindly suggests me

I just downloaded the newest version of Adobe Reader to my MAC, I need help now please

The End user license agreement did not appear to sign and accept. So now when I open another site to download pdfs, it says I need to launch Adobe Reader and accept the End User License Agreement, then Quit and relaunch the browser.
I cannot launch Reader to get to the End User Agreement. Can you help me please

What happens when you try launching Reader?

Adobe Reader in browser window disappearing-need help

I have created a word document (WD1) containing links to other word documents (WD2, WD3, etc). I then turned WD1 into a .pdf file. I then upload this .pdf file to a web page. I go to this webpage and click the link to open the WD1.pdf file. When I click the WD1.pdf link on the webpage, a new browser window opens with Adobe reader in it displaying WD1.pdf. so far so good. Now when I click on the links to WD2 or WD3, these links open in Word and the correct files display, but the browser window containing WD1.pdf file disappears (thats the best way to describe it) and the first webpage is still open.
What I am trying to achieve is to have the second browser window stay open so the trainees using this web page will be able to click on the other references on the .pdf to get to all of the links without having to re-open it each time.
I have Researched in help and web forums, the only reference I can find is to uncheck the box next to Open cross-documents in the same window in preferences in Adobe. Which I have done and restarted my computer. I also noticed a preference show each document in its own window which is checked.
Here is the other rub, I have a desktop computer (OS is XP) and a laptop (OS is vista). I have Adobe 8.1.2 installed on both. The laptop with vista works the way I would like. But the desktop computer with XP does not. I did have Adobe 7.0.9 on the desktop but when it did do what I wanted I upgraded to 8.1.2 and it still isnt working. The real problem is that most of the trainees will be using their work computers with XP. I dont know even know if there is any significance in this observation or not. But thought I would throw it out there.
Does anyone have any suggestions of things I could try or know of any solutions? Please help.

There is a technology on Labs called BrowserLab that is designed to assist with browser compatibility. Is this question regarding BrowserLab or is the question more general?

10.6.4 Woes - Read many threads but still need help!

Howdy all!
Here's the deal, I'm having problems which I can only trace back to the upgrade to 10.6.4. Everything seemed to be fine for a couple of weeks but something happened when I set-up my new office in my house (external monitor, hard drives etc) I've read so many threads and have tried different things but now am at a loss. I'm way out of warranty so I can even go to the Genius bar or will they charge me? Here's the gist.
Symptoms:
A) Long boot on gray screen, once finder is open the system is frozen for like 10 minutes, dock won't pop up etc. Mouse can move but won't click anything. After 10 minutes things seem to be fine.
B) Computer won't wake up from sleep mode (like if I close the laptop cover) but it will wake-up if the display has gone off
C) Firewire seems to no longer work
Here's what I have tried already:
1) Installed the combo update (fresh download)
2) Repaired permissions (several times and it keeps finding them)
3) Trashed my firewire port (no change)
4) Disable airport (and basically what happens when I do this is that instead of waiting 10 minutes with just a mouse arrow, I have a beachball (non-spinning) for 10 minutes which then disappears when the machine decides to work) At one point I had a hazy blue screen over my desktop and that disappeared after 10 minutes but I've only had that happen one time
5) My disk is OK per Disk Utility, and it says its S.M.A.R.T. status is enabled (or whatever it is supposed to say I forget at the moment but I checked it as one thread suggested and it was as it is supposed to be)
6) The machine boots fine in safe mode - though it is still a long boot but you can use it as soon as the finder loads.
7) The only thing I haven't done is zap my pram (will this help?) and how do you do it?
Thoughts? I can roll back to 10.6.3 which I know has pros and cons but at least it works.
My Applecare ran out and I'm pretty broke at the moment so I don't want to pay for support if I don't have to (although it's more than I don't want to spend a lot of time at the Apple Store to find out something I already know - that 10.6.4 is buggy!(
Help please and thanks so much! Sorry for the long post but I thought I would try to save some questions. I've read so many threads it was all running together.

Oh and yet a new symptom - I can't seem to sync my iPhone 3G. I could sync the photos to iPhoto, but not iTunes, it keeps timing out!

Problems with Vista and Reader 8.12 - unusual problem need help

I can't seem to find anyone to help me or any record of someone else having this problem. As soon as I install reader 8.12 on my new system (Vista) it begins 'hijacking' other files. In other words other icons on my desktop (e.g., the icon for AOL IM) turn into PDF icons and so when I try to launch an .exe file - Reader launches instead and of course tells me it can't open the file. This is so maddening. I've installed and unstalled the program several times and have rebooted. I've tried to contact Adobe but they will not provide support, I've contacted Gateway and they say it's an Adobe issue and Microsoft won't speak with me because Vista was pre-installed on the computer. If anyone has any ideas and can assist me I'd greatly appreciate it. For now I just have to leave the program uninstalled and therefore can't open any PDFs.
Anita

It seems that in Vista bad things may happen if you ever choose a
program to open downloaded EXE files.
This may help with the EXE issue:

My iPhone 5 was stolen, and i just recieved my new iPhone 5c in the mail. i turned it on and went through the set up instructions assuming it would lead me to the acivation process but it did not. I now have a phone that works with everything but calls and texts. I looked up online and it said you can activate it through itunes, i downloaded itunes onto my computer and plugged my phone in to it using the USB port and still nothing. will someone please help!

Take the phone into your nearest Verizon store. They will activate it for you. If you really cant do that, call Verizon Customer Service back, explain you've been unable to activate it and have them walk you through it.
Best of luck.

Instead of removing the music from the cloud or the iTunes library why not shuffle your music using a Smart Playlist which excludes the holiday music, or tracks that are not checked. For example, use this very simple Smart Playlist:

16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
          XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
          xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
     XmlIndexSpecification spec = container.getIndexSpecification();
     // ids
     spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // index to cover AttributeValue/Description
     spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
     // cover AttributeValue/@value
     spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // item attribute values
     spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // default index
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
     // save the spec to the container
     XmlUpdateContext uc = xmlManager.createUpdateContext();
     container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
     No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav

Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query     { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.

Need help with Adobe Reader 9

About three weeks ago my computer started acting crazy so I tried to run updates but I could not get on the internet because the comcast guy told me that it was my firewall. So I disabled my firewall and put on windows firewall and was able to do my updates, but then my antivirus quit working so then I uninstalled it and tried to reinstall but I could not. So I got mad and tried to restore to my last restore point but it would not let me, so when I went to run check disk Windows popped up and said it could not perform this action because the disk was busy.So I then called my friend whorepairs computers and he came over and ran combofix and installed a new antivirus. Combofix said nothing was wrong, but I still can't do system restore or checkdiscso I ran MalwareBytes and it comes up with nothing. So now all of a sudden Windows is telling me that Adobe reader 9 is corrupt and unreadable. Everytime I try to uninstall it, it won't let me. Everytime I try to install a newer version I can't because a pop up comes up and says I alredy have the file, but I can't use it to read my PDFs for class. Adobe reader 9 is messing my computer up and I need help removing it?

Hello,this is me again. I ran Windows install utility cleanup and basically uninstalled all Adobe files, but when I was done I went into the program files on C drive to delete Adobe file and it gave me an error that said: An unexpected error is preventing the operation.Make a note of this error code,which might be useful if you get additional help to resolve this problem.Error 0x80070091: The directory is not empty. And I still cannot run check disc because it tells me that the disk is busy.

Need help in optimising the performance of a query

Need help in optimising the performance of a query. Below is the query that is executed on TABLE_A, TABLE_B and TABLE_C with record counts as 10M, 10m and 42 (only) respectively and it takes around 5-7 minutes to get 40 records:
SELECT DISTINCT a.T_ID_, a.FIRSTNAME, b.T_CODE, b.PRODUCT,
CASE WHEN TRUNC(b.DATE) +90 = TRUNC(SYSDATE) THEN -90 WHEN TRUNC(b.DATE) +30 = TRUNC(SYSDATE) THEN -30 ELSE 0 END AS T_DATE FROM TABLE_B b
INNER JOIN TABLE_A a ON (a.T_ID_ = b.T_ID_) LEFT JOIN TABLE_C c ON b.PRODUCT = c.PRODUCT
WHERE b.STATUS = 'T' AND (b.TYPE = 'ACTION'
AND ( TRUNC(b.DATE) + 1 = TRUNC(SYSDATE) ) ) AND b.PRODUCT = 2;
Note: Indices on the join columns are available in the respective tables
Please let me know if there is any better way to write it.
