Instability and Poor Performance with 11 11/11 and 11.1

I've upgraded an OpenSolaris install to Solaris 11.1 over time and ever since I hit Solaris 11 11/11 and Solaris 11.1 my system has been unstable and slow (especially ZFS and GDM (which I had to disable in 11/11.1 because it was using too much CPU)). Whenever I shut down in Solaris 11/11.1 it causes a kernel panic. I run this command to shutdown:
/usr/sbin/shutdown -y -g 60 -i 5
and it causes this (then the system auto-restarts -- it never completes the shutdown):

Additionally, I've seen a huge slowdown in ZFS performance (I kept the old boot environments for the previous versions so I went back and pulled these #s using dd after I upgraded to Solaris 11.1):

Lastly, there's been a couple times where just running tests on my zfs pool would cause a kernel panic (like dd or bonnie++):

What could be causing all these issues -- why are the OpenSolaris and Solaris 11 Express installs faster/more stable? Is it a hardware incompatibility issue? How can I determine the root cause and fix it?
Thanks.

Alan, if the cause is a 5400 RPM drive, I'm not sure why when I boot into my older BEs for Opensolaris/Solaris 11 Express/OpenIndiana I see much better ZFS performance. After I upgraded to 11.1 I noticed slowness and went back to my old Boot Environments and generated the dd read/write speeds I put in the top post, so it's not like any of the hardware changed during that hour I was bench marking between BEs nor did the amount of space used in my zpool change (it is mostly empty and I deleted everything that I wrote with dd after each test).

Safari hangs and poor performance in MBPR (Mid 2012)

Safari hangs and poor performance in MBPR (Mid 2012)? OS X 10.10.2 is up to date

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Back up all data before making any changes.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If the Downloads button (with the icon of a downward-pointing arrow) is showing in the toolbar, click it and then click Clear in the box that appears. The download history will be removed. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Follow the instructions in this support article. Any change?
Open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Non jdriver poor performance with oracle cluster

Hi,
we decided to implement batch input and went from Weblogic Jdriver to Oracle Thin 9.2.0.6.
Our system are a Weblogic 6.1 cluster and an Oracle 8.1.7 cluster.
Problem is .. with the new Oracle drivers our actions on the webapp takes twice as long as with Jdriver. We also tried OCI .. same problem. We switched to a single Oracle 8.1.7 database .. and it worked again with all thick or thin drivers.
So .. new Oracle drivers with oracle cluster result in bad performance, but with Jdriver it works perfectly. Does sb. see some connection?
I mean .. it works with Jdriver .. so it cant be the database, huh? But we really tried with every JDBC possibility! In fact .. we need batch input. Advise is very appreciated =].
Thanx for help!!

Thx for quick replys. I forget to mention .. we also tried 10g v10.1.0.3 from instantclient yesterday.
I have to agree with Joe. It was really fast on the single machine database .. but we had same poor performance with cluster-db. It is frustrating. Specially if u consider that the Jdriver (which works perfectly in every combination) is 4 years old!
Ok .. we got this scenario, with our appPage CustomerOverview (intensiv db-loading) (sorry.. no real profiling, time is taken with pc watch) (Oracle is 8.1.7 OPS patch level1) ...
WL6.1_Cluster + Jdriver6.1 + DB_cluster => 4sec
WL6.1_Cluster + Jdriver6.1 + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_cluster => 8-10sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_single => 4sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_cluster => 8sec
WL6.1_Cluster + Ora10.1.0.3 thin + DB_single => 2-4sec (awesome fast!!)
WL6.1_Cluster + Ora10.1.0.3 thin + DB_cluster => 6-8sec
Customers rough us up, because they cannot mass order via batch input. Any suggestions how to solve this issue is very appreciated.
TIA

It's much faster than any 9.X

Poor Performance with Fairpoint DSL

I started using Verizon DSL for my internet connection and had no problems. When Fairpoint Communications purchased Verizon (this is in Vermont), they took over the DSL (about May 2009). Since then, I have had very poor performance with all applications as soon as I start a browser. The performance problems occur regardless of the browser - I've tried Firefox (3.5.4), Safari (4.0.3) and Opera (10.0). I've been around and around with Fairpoint for 6 months with no resolution. I have not changed any software or hardware on my Mac during that time, except for updating the browsers and Apple updates to the OS, iTunes, etc. The performance problems continued right through these updates. I've run tests to check my internet speed and get times of 2.76Mbps (download) and 0.58Mbps (upload) which are within the specified limits for the DSL service. My Mac is a 2GHz PowerPC G5 runnning OSX 10.4.11. It has 512MB DDR SDRAM. I use a Westell Model 6100 modem for the DSL provided by Verizon.
Some of the specific problems I see are:
1. very long waits of more than a minute after a click on an item in the menu bar
2. very long waits of more than two minutes after a click on an item on a browser page
3. frequent pinwheels in response to a click on a menu item/browser page item
4. frequent pinwheels if I just move the mouse without a click
5. frequent messages for stopped/unresponsive scripts
6. videos (like YouTube) stop frequently for no reason; after several minutes, I'll get a little audio but no new video; eventually after several more minutes it will get going again (both video and audio)
7. response in non-browser applications is also very slow
8. sometimes will get no response at all to a mouse click
9. trying to run more than one browser at a time will bring the Mac to its knees
10. browser pages frequently take several minutes to load
These are just some of the problems I have.
These problems all go away and everything runs fine as soon as I stop the browser. If I start the browser, they immediately surface again. I've trying clearing the cache, etc with no improvements.
What I would like to do is find a way to determine if the problem is in my Mac or with the Fairpoint service. Since I had no problems with Verizon and have made no changes to my Mac, I really suspect the problem lies with Fairpoint. Can anyone help me out? Thanks.

1) Another thing that you could try it is deleting the preference files for networking. Mac OS will regenerate these files. You would then need to reconfigure your network settings.
The list of files comes from Mac OS X 10.4.

2) I think it is time to do a clean install of your system.
3) It's either the software or an intermittent hardware problem.
If money isn't an issue, I suggest an external harddrive for re-installing Mac OS.
You need an external Firewire drive to boot a PowerPC Mac computer.
I recommend you do a google search on any external harddrive you are looking at.
I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.
The latest the hard drive enclosures support the newer serial ata drives. The drive and closure that I list supports only older parallel ata.
Has everything interface:
FireWire 800/400 + USB2, + eSATA 'Quad Interface'
save a little money interface:
FireWire 400 + USB 2.0
This web page lists both external harddrive types. You may need to scroll to the right to see both.

Poor Performance with my new System

Hi All,
Great Forum. Hopefully someone here can provide me some direction. I just built my first AMD based system (spec's below). Everything is running smooth and stable, but I dont believe I am getting the performance out of this rig as I should. Specifically, I am getting very low scores on 3Dmark05 (5100 - 5300) with my rig at stock settings.
I've surfed through these forums for days and found many folks getting much better performance out of components that are not as robust as mine. So, I am looking for some guidance. So far, Here's what I've done:
1: Bios: I've disabled the "smart & cool"
all of the "aggressive timings" are disabled
Video is selected to AGP (128mg since that's what the BFG Technician recommended for the 256mg GPU's)
boosted video voltage to 1.6v
Manually set all of the ram timings (listed below in the system description)
Processor HT is set to 5x (i got this from the AMD site)
most of the other settings are set to auto.
2: Temps: The CPU is currently idling around 42 degrees. 46 under load
The GPU is idling around 62 degrees. this seems a bit high, but i havent been able to verify.
3: CPU Scores in 3DMark05 are in the mid-high 6000's
Ive also tried to load the registry oc program for the GPU (from guru) and it only made things worse. standard clock settings (factory oc'd) work best. The system is extremely stable and runs quite smoothly. It's very quiet and cool (42-46 cpu, 34 ambient)
I am not sure where I went wrong here, but something is just not making sense. I've read posts where folks are getting scores in the 10's and 11's with lesser processor and GPU gear. Any directions here would be greatly appreciated. Hopefully i've posted enough information. Thanks for your help!
MB: MSI K8N Neo Platinum
Award BIOS, v1.8
PROC: AMD Athlon 64 4800+ (42 degrees idle, 46 degrees loaded)
MEM: 2x Corsair TwinX-3200C2-Pro (2.5, 3, 3, 6, 1T @ 2.7 volts)
GPU: BFG GeForce 6800GT OC 256MB AGP, nVidia v78.01
PSU: UltraX-Connect 500W
HD: WD Raptor 74G 10,000 rpm
CD: Plextor DVD-R/W
FAN/HS: XP-90 e/w SilentCat fan (yes, it fits with the memory in slots 3&4. No problems with this with the new bios. All is stable and runs well)
Windows XP SP2

Thanks for the replys guys.
I did read a few threads where folks were boasting numbers in the 10's and 11's. From your notes, it appears that they were simply blowing smoke. I appreciate knowing that, although I dont understand the purpose of posting inaccurate information in these forums. These are (and will continue to be) and excellent resource unless they become clogged with garbage.
As far as temperatures on the GPU, I figured it was a bit high, but according to BFG, it's good to 120C (that seems way outta line). i imagine that i would get a bit better performance from it by replacing the stock heatsink/fan combo with an aftermarket GPU cooler from Zalman. The right thing to do is to replace my MB with a ASUS SLI-Premium and put a couple of 6800 Ultra's in it (lol).
I appreciate the information. It appears that i have achieved the maximum from my PC, and as I stated before, it runs great. Thanks again for the help guys. If I get rich and decide to change out the guts for an SLI set up, I'll let you know. Until then, I think i'll grab a GPU cooler and see if I can get the temps down a bit.
Is there any benifit to removing the stock Heatsink/Fan and trying some Artic Silver 5 in there? I've heard a few folks have gotten some decent results doing that.
Thanks again

Commit work and roll back with simple language and simple example

hi guru
commit work and roll back with simple language and simple example

Hi,
The statement COMMIT WORK completes the current SAP LUW and opens a new one, storing all change requests for the current SAP LUW in the process. In this case, COMMIT WORK performs the following actions:
It executes all subroutines registered using PERFORM ON COMMIT.
The sequence is based on the order of registration or according to the priority specified using the LEVEL addition. Execution of the following statements is not permitted in a subroutine of this type:
PERFORM ... ON COMMIT|ROLLBACK
COMMIT WORK
ROLLBACK WORK
The statement CALL FUNCTION ... IN UPDATE TASK can be executed.
ROLL BACK:
The statement ROLLBACK WORK closes the current SAP-LUW and opens a new one. In doing so, all change requests of the current SAP-LUW are canceled. To do this, ROLLBACK WORK carries out the following actions:
1) Executes all subprograms registered with PERFORM ON ROLLBACK.
2) Deletes all subprograms registered with PERFORM ON COMMIT.
3) Raises an internal exception in the Object Services that makes sure that the attributes of persistent objects are initialised.
4) Deletes all update function modules registered with CALL FUNCTION ...IN UPDATE TASK from the VBLOG database table and deletes all transactional remote Function Calls registered with CALL FUNCTION ... IN BACKGROUND TASK from database tables ARFCSSTATE and ARFCSDATA.
5) Removal of all SAP locks set in the current program in which the formal parameter _SCOPE of the lock function module was set to the value 2.
6) Triggers a database rollback, which also ends the current database-LUW.

Where's the music on iTunes, and what's with the quality and compatibility?

I'm just curious as to whether anyone else has had this issue or not: Does anyone else feel like, after searching for specific songs, there's just little to nothing in the database? I feel like most of my searches are pointless because iTunes has either no data of my requested search and/or only has bits and pieces of it.
Another question I have: After having a slightly successful search, why am I left with low quality tunes? I mean, you can hear the compression... badly. (I know it's not my speakers)
Last question: If I'm paying for the song, shouldn't I be allowed to download a universal file? iTunes uses a unique format that no other application uses. In other words, more money has to be spend for m4a to mp3 converters (unless you're a cracker [not a racial comment]).
To me, I value iTunes and its team, so I'm sorry if I've offended anyone. I understand there are contracts involved with the artists and it's hard to please ALL of the subscribers. But seriously, where's the music on iTunes, and what's with the quality and compatibility?
Custom Windows XP Pro Negative, I am a meat popsicle.

Today I thought of finally putting lyrics on my songs. So I've been quite some time busy doing that, then I tried it on my iPad (2) and I can't find them. Just as the people above say. Then I went to search where I can find them and I found this page. I'm really dissapointed and I don't understand how something like this could happen. So I hope Apple will fix this soon.
(I'm just posting this so that Apple will do something about it)

When you synced in iTunes did you select your phone in devices on t left column and then click on tones int eh window on the right.

Hello _slothy_,
Thank you for the details of the issue you are experiencing with the iTunes Store on your iPhone 5c. For this issue, I recommend signing out and back into the iTunes Store on your iPhone:
Sign in with a different Apple ID
Tap Settings > iTunes & App Stores.
Tap your Apple ID.
If you see the option to Sign In, you can change your Apple ID now.
Tap Sign Out.
Enter your Apple ID and Password and tap Sign In.

If the issue persists after signing out and back in, I recommend quitting and relaunching the applications on your iPhone:
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.

If you are still seeing the same issue after quitting and relaunching the iTunes Store app, I recommend restarting your phone and then resetting if it's still not working:
How to restart
Press and hold the Sleep/Wake button on the top of your device until the red slider appears. Then drag the slider to turn your device completely off.
After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo.
How to reset
You should reset your device as a last resort and only if you can't restart it.
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.

Hello Hoppayoppa
You would need to have the owner of that iCloud account to turn off. It can be done without them there. Check out the article below for more information. After that is done, you can put the correct backup on your iPhone.
