Performance...SUBSTR Vs LIKE

hi -
what would be more efficient between a query using
where substr(client_no,1,4) = '9999'
or where client_no like '9999%'
any ideas?
thx

1) It depends on a lot of different factors-- you'd have to benchmark in your particular environment with your particular data, your particular indexes, etc.. If you really have numeric data in a character column, Oracle's estimation of the selectivity of the LIKE clause is likely to be way off (since Oracle assumes each character can be one of 128 different values while in reality there are only 10 options). On the other hand, it's relatively easy to create a function-based index on SUBSTR( client_no, 1, 4 ) assuming that predicate is appropriately selective.
2) I'm generally wary of logic that involves comparing substrings from a column because that implies that the column is not properly normalized. If a CLIENT_NO is composed of multiple components with independent meaning, you ought to store the data in its decomposed form.

Wow. Okay...
I'll let the real veterans in this forum tackle your issues one after the other. But, I can tell you, all will be well.
My only comment would be re: your computer specs:

To be completely honest, FCPX is a RAM hog. It just is. But, RAM is relatively cheap, and the pay-off is good.
4GB is right on the edge, IMHO. 16G is ideal.
I wish you luck, hang in there, and standby for more help.

Performance difference between LIKE and "="

May I know what will be the performance difference for
select * from a where b = 'C'
v.s.
select * from a where b like 'C'
In general, we don't notice any performance difference in using "LIKE" but under some situation we do. Any idea why?

Equality is a relatively easy thing for the cost-based optimizer (CBO) to handle, so it is far more likely that it will generate the "right" query plan.
It is a lot more difficult for the CBO to estimate how many rows a LIKE query will return, particularly since the vast majority of LIKE clauses have wild-cards. I would not be suprised if the CBO were occasionally generating incorrect plans if you are using LIKE where you could be using =.

Is creating a script to perform a task like this possible?

This is what I am trying to do:
-If the Mac is asleep it will need to automatically wake and perform these tasks:
-On Monday, Wednesday and Friday @ 4:55 pm I want to open each of these browsers (which may or may not already be opened): Safari, FireFox, Chrome.
-I want each browser to open a new tab and go to website "ABC"
-At website "ABC" I want each browser to input a unique username and password and sign in (unless already signed in).
Can this be done?
Thanks,
Nick

Nope, but it depends on your time frame and interest (i.e, are you only interested in getting this functionality or are you interested in learning how to script too?).
I'd suggest you start with a good book. I recommend
http://www.amazon.com/Apple-Training-AppleScript-Sal-Soghoian/dp/0321149319
You should be up and running and able to adapt what you learn from that after only a few chapters.
Once you've got the general idea of how scripts work and what handler routines your script needs, you'll be able to fill in the details with specific web searches.
An excellent source for all things applescripty is

Pages are not loading properly and can't perform simple functions like forwarding e-mail, whats wrong?

When I sign into my Yahoo account the mail page doesn't load correctly and prompts me to turn off automatic updates. I can't send or forward any e-mails in the mail section. When I sign into Facebook I can't poke people back, look at mail friend requests or notifications. And applications don't load at all. When I sign into my checking account I can't view the account page..it's all scrambled. And other web sites are scrambled looking also.

Smartview 9.3 version performing excel functions like addition

Hello All,
Is it possible for me to add up more than one account in a single cell within smartview for hyperion and if so how do i go about it. For example, I want to add up two inventory accounts (Member selection-Account) and show the total in one cell for a particular entity (member selection-Tier) for a given market (member selection-Custom 1). I cant come up with the solution. I dont know if it is something that the query designer or function member can do. I am a regular user and dont have admin rights. thanks, Aby

You would need to use Excel functionality for this. You can use cell functions with Excel formulas to just bring both member on the grid and then use excel formulas.

Can FCPX perform screen capture like ISHOWU HD does?

My daughter uses Adobe Photo shop to draw, she records the whole drawing session with ISHOWU HD as a video which is saved in iMovie. With Snow Leopard this worked flawlessly. Once I upgraded to Lion I found out that ISHOWU HD has some problems with Lion, rendering ISHOWU pretty much unuseable. The developer says is going to take a while to fix it. Can FCPX capture a screen in real time as a video and work the same way.

Bind variable & LIKE :1 - Performance issue

I'm using ODP.NET version 10.2 and I'm facing a performance problem with LIKE key word in statements.
I'm doing the following :
OracleConnection conn = new OracleConnection();
conn.ConnectionString = connectionString;
string strQuery;
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
strQuery = "SELECT field FROM table WHERE field LIKE :1";
cmd.Parameters.Add(":1", OracleDbType.Varchar2, 2, "x%",ParameterDirection.Input);
-> This takes quite a long time to retrieve the data.
If I do the following (without Parameters.Add) it flies :
strQuery = "SELECT field FROM table WHERE field LIKE 'x%'";
cmd.CommandText = strQuery;
OracleDataAdapter da = new OracleDataAdapter();
da.SelectCommand = cmd;
DataSet ds = new DataSet();
da.Fill(ds, "table");
What am I doing wrong ?
Thanks in advance
Philippe

Hi,
Is this behavior specific to ODP.NET? Do you get the same behavior testing sqlplus with bind variables? If you're not sure how, here's how you can try it..
Cheers,

Performance of layer 3 switches when they are acting like a router

Hi everybody
I want to know what are the performance differences of layer 3 switches when they are acting just like a router with lots of route entries in their routing table in compare to when they are acting in layer 2?
The layer 3 switch in our case is “WS-C3750X-24T-S”
I guess there is a difference between these two situations:
when the switch is acting in layer 3 and just routes packet between different VLAN (in routing table we just have entries for connected interfaces and nothing else)
when the switch is acting in layer 3 and also has to do routing based on static routes or routes learned via a routing table
I think in situation 1 the switch performance is just like when it is acting in layer 2 but I don’t know about situation 2. Does anyone know about this?
Thanks a lot

Hello.
Actually there is no difference unless you reach a capacity limit of routing table and other TCAM entries.
Also you need to note that some IOSs do not support full (but stub only) EIGRP functionality.
PS: see details regarding routing capacity.

[CC] How to perform a script "foo_beforeSave.htm" only for specific site?

Since a long time I use a script for automatic text replacements which perform with each save command.
The script sits in that folder:
C:\Users\myusername\AppData\Roaming\Adobe\Dreamweaver CC\de_DE\Configuration\Commands\foo_beforeSave.htm
It works for all documents of all sites.
The source code (the regex rule is just an example) of the script you find below.
My question:
I like to perform a script like this only for a specific site.
I'm not a programmer. So I don't know where to place the script to reach that target. Or how I have to edit the source code of the script.
Is there anybody who could help me with that please?
I would appreciate it a lot. Thanks

Windows 2012 Nodes - Slow CSV Performance - Need help to resolve my iSCSI issue configuration

I spent weeks going over the forums and the net for any publications and advice on how to optimize iSCSI connections and i'm about to give up. I really need some help in determining if its something i'm not configuring right or maybe its an equipment
issue.
Hardware:
2x Windows 2012 Hosts with 10 Nics (same NIC configuration) in a Failover Cluster sharing a CSV LUN.
3x NICs Teamed for Host/Live Migration (192.168.0.x)
2x NICS teamed for Hyper-V Switch 1 (192.168.0.x)
1x NIC teamed for Hyper-V Switch 2 (192.168.10.x)
4x NICs for iSCSI traffic (192.168.0.x, 192.168.10.x, 192.168.20.x 192.168.30.x)
Jumbo frames and flow control turned on all the NICs on the host. IpV6 disabled. Client for Microsoft Network, File/Printing Sharing Disabled on iSCSI NICs.
MPIO Least Queue selected. Round Robin gives me an error message saying "The parameter is incorrect. The round robin policy attempts to evenly distribute incoming requests to all processing paths. "
Netgear ReadyNas 3200
4x NICs for iSCSI traffic ((192.168.0.x, 192.168.10.x, 192.168.20.x 192.168.30.x)
Network Hardware:
Cisco 2960S managed switch - Flow control on, Spanning Tree on, Jumbo Frames at 9k - this is for the .0 subnet
Netgear unmanaged switch - Flow control on, Jumbo Frames at 9k - this is for .10 subnet
Netgear unmanaged switch - Flow control on, Jumbo Frames at 9k - this is for .20 subnet
Netgear unmanaged switch - Flow control on, Jumbo Frames at 9k - this is for .30 subnet
Host Configuration (things I tried turning on and off):
Autotuning
RSS
Chimney Offload
I have 8 VMs stored in the CSV. When try to load all 8 up at the same time, they bog down.  Each VM loads very slowly and when they eventually come up, most of the important services did not start. I have to load
them up 1 or 2 at a time. Even then the performance is nothing like if they were loading up on the Host itself (VHD stored on the host's hdd). This is what prompted me to add in more iSCSI connections to see if I can improve the VM's
performance.  Even with 4 iSCSI connections, I feel nothing has changed. The VMs still start up slowly and services do not load right. If I distribute the load with 4 VMs on Host 1 and 4 VMs on Host 2, the load up
times do not change.
As a manual test for file copy speed, I moved the cluster resources to Host 1 and copied a VM from the CSV and onto the Host.   The speed would start out around 250megs/sec and then eventually drop down to about 50/60 megs/sec. If I turn
off all iSCSI connections except one, it get the same speed. I can verify from the Windows Performance Tab under Task Manager that all the NICS are distributing traffic evenly, but something is just limiting the flow. Like what I stated on top,
I played around with autotuning, RSS and chimney offload and none of it makes a difference.
The VMs have been converted to VHDx and to fixed size. That did not help.
Is there something I'm not doing right? I am working with Netgear support and they are puzzled as well. The ReadyNas device should easily be able to handle it.
Please help! I pulled my hair out over this for the past two months and I'm about to give up and just ditch clustering all together and just run the VMs off the hosts themselves.
George

A few things...
For starters, I recommend opening a case with Microsoft support. They will be able to dig in and help you...
Turn on the CSV Cache, it will boost your performance
http://blogs.msdn.com/b/clustering/archive/2012/03/22/10286676.aspx
A file copy has no resemblance of the unbuffered I/O a VM does... so don't use that as a comparison, as you are comparing apples to oranges.
Do you see any I/O performance difference between the coordinator node and the non-coordinator nodes? Basically, see which node owns the cluster Physical Disk resource... measure the performance. Then move the Physical Disk resource for the
CSV volume to another node, and repeat the same measure of performance... then compare them.
Your IP addressing seems odd... you show multiple networks on 192.168.0.x and also on 192.168.10.x.   Remember that clustering only recognizes and uses 1 logical interface per IP subnet. I would triple check all your IP schemes...
to ensure they are all different logical networks.
Check you binding order
Make sure you NIC drivers and NIC firmware are updated
Make sure you don't have IPsec enabled, that will significantly impact your network performance
For the iSCSI Software Initiator, when you did your connection... make sure you didn't do a 'Quick Connect'... that will do a wildcard and connect over any network. You want to specify your dedicated iSCSI network
No idea what the performance capabilities of the ReadyNas is... this could all likely be associated with the shared storage.
What speed NIC's are you using?   I hope at least 10 GB...
Hope that helps...
Elden
Hi Elden,
2. CSV is turned on, I have 4GB dedicated from each host to it. With IOmeter running within the VMs, I do see the read speed jumped up 4-5x fold but the write speed stays the same (which according to the doc it should). But even with the read
speed that high, the VMs are not starting up quickly.
4. I do not see any difference with IO with coordinator and non coordinator nodes.
5. I'm not 100% sure what your saying about my IPs. Maybe if I list it out, you can help explain further.
Host 1 - 192.168.0.241 (Host/LM IP), Undefined IP on the 192.168.0.x network (Hyper-V Port 1), Undefined IP on the 192.168.10.x network (Hyper- V port 2), 192.168.0.220 (iSCSI 1), 192.168.10.10 (iSCSI2), 192.168.20.10(iSCSI 3), 192.168.30.10 (iSCSI 4)
The Hyper-V ports are undefined because the VMs themselves have static ips.
0.220 host NIC connects with the .231 NIC of the NAS
10.10 host NIC connects with the 10.100 NIC of the NAS
20.10 host NIC connects with the 20.100 NIC of the NAS
30.10 host NIC connects with the 30.100 NIC of the NAS
Host 2 - 192.168.0.245 (Host/LM IP), Undefined IP on the 192.168.0.x network (Hyper-V Port 1), Undefined IP on the 192.168.10.x network (Hyper- V port 2), 192.168.0.221 (iSCSI 1), 192.168.10.20 (iSCSI2), 192.168.20.20(iSCSI 3), 192.168.30.20 (iSCSI 4)
The Hyper-V ports are undefined because the VMs themselves have static ips.
0.221 host NIC connects with the .231 NIC of the NAS
10.20 host NIC connects with the 10.100 NIC of the NAS
20.20 host NIC connects with the 20.100 NIC of the NAS
30.20 host NIC connects with the 30.100 NIC of the NAS
6. Binding orders are all correct.
7. Nic drivers are all updated. Didn't check the firmware.
8. I do not know about IPSec...let me look into it.
9. I did not do quick connect, each iscsi connection is defined using a specific source ip and specific target ip.
These are all 1gigabit nics, which is the reason why I have so many NICs...otherwise there would be no reason for me to have 4 iscsi connections.

Need to Optimize 3D performance on an Envy 17 3D? (...and other random bits)

Hey there,
The name's Darren. Nice to meet you. While I'm new to posting around these parts, I have been lurking for a little bit. Here's the deal: I work for another part of HP -- I run the blog, thenextbench.com. There, I'm working on various stories: How-tos, tweaks, tips and whatnot. What I'm wondering is if you guys would find it useful for me to post bits of some of my stories here. For example, I did one a while back about setting up games to work in 3D on an ENVY 17 3D....and getting better performance.
(The story originally ran here)
You’ve bought an ENVY 17 3D. Awesome. You’re rocking it with 3D movies and I’m going to make the wild assumption that you’ve played some games since the Envy 17 3D got updated with that snazzy TriDef 3D ignition software. It’s actually dead-simple to get up-and-running with its 300-plus supported games…but what if there is no preset profile for that brand new game you just bought or that super-obscure title you downloaded from some cool, underground hipster indie gaming site? Well, I’ve been tinkering a little with this machine and wanted to walk you through the proper steps to get you situated. So strap those fancy goggles firmly to your noggin and read on, my friends.
For the sake of this story, I’m going to walk you through how I got things set up, step-by-step. If any of this seems a little redundant, bear with me. Also, the fine folks at TriDef have been great to work with on this - and while I don’t have all the answers, feel free to hit the comment box below and I’ll do my best to get the straight scoop from them. Also, I’d highly recommend youcheck the ddd forums as well. It is a VERY handy resource for 3D gaming on the ENVY 17 3D.
STEP 1: The initial setup
The first time you run the TriDef 3D Ignition software, hit the “Scan” button. It checks directories for known EXE files and instantly populates them on the game launch list. If you installed a popular game directly from a disc, it usually doesn’t have a problem. But if you’re like me, you download your games from digital download services like Steam. (What can I say? I lose discs all the time.) That’s when it gets a little trickier. The game is afoot!
STEP 2: Manually adding a game
Click the “Add” button and it calls up a window. The first thing to look at is the drop down menu. It contains a current list of all the games automatically supported. Your game not there? Don’t sweat it yet. There’s a link in the window to the TriDef forums – there is an active community of users always creating new game profiles for you to download. Still nothing? There is still hope. Select the “Generic” profile for now. We’ll get back to that in Step 3.
In the same window, you’re going to see a prompt to find the game location. You can either click a shortcut to the game or find the actual EXE file yourself. After that, make sure you create a name for the profile and save it.
STEP 2a: Adding a Steam game
I figured that it’d be a piece of cake. And it was at first. I downloadedBorderlands through Steam and when I created a profile pointing to the game file in the Steam directory, everything was groovy.
(PROTIP: The TriDef software can work with game shortcuts, but Steam holds its game files in the “\Steam\steamapps\common” directory).
Many other Steam-downloaded games started giving me this oddball warning: “This game doesn’t support DirectX 9, 10 or 11.” These were new games – OF COURSE they supported the latest DX files. So I did a little digging and there is an extra step required to make some Steam games work.
     1.       Click the “Add” button in the TriDef menu
     2.       In the “Executable” field, point to the “steam.exe” file in the main Steam directory.
     3.       Find a shortcut for the game you want to download. (If you don’t have one, open up the Steam client, right-click on the game and select “create shortcut on desktop.”)
     4.       Right-click on the shortcut for the game. At the end of the link location it’ll have a number. Copy that number
     5.       Within the TriDef’s Add window, enter “-applaunch [NUMBER]” in the field where it says “Command Line Arguments (optional)”
     6.       Look for the game’s profile as described above in Step 2.
     7.       Save your progress.
STEP 3: Optimizing your 3D performance
Once you’ve cleared those first couple steps, it’s actually not that bad from here. You just want to optimize the experience so that you can get good 3D effects and keep the game playable. What you have to remember is that in order to render a 3D image, the Envy is effectively doubling what’s happening on-screen. My gut reaction with any game is to run it at the laptop’s native screen resolution (1920 by 1080). It looks pretty and can handle running those games in 2D just fine. Bring 3D into the equation and your frame rate will drop. But with a couple tweaks, I’ll get you back up to speed.
     1.       First, start up a test game and just sit around in the game environment, not the game menus.
     2.       Next, on your computer’s number pad, hit the “0” key to call up the 3D overlay menu. Use the 8 and 2 to navigate up and down and the 6 key to make selections.
     3.       Push 2 until the “Performance” option is highlighted and hit the 6 key. There you should see the frame rate displayed (It’s labeled “FPS”). If the FPS number is above 30, youshould be fine. That, of course, can change if there’s a lot of action happening on screen. In short, the higher the frame rate, the better.
        a.       If your frame rate is below 30, consider lowering the game’s resolution or move the cursor in the 3D overlay menu and lower the game’s 3D effects settings. Just highlight “Quality” and push the 6 to toggle the 3D effects between High, Medium and Low.
     4.       When you find the performance settings you like, hit Alt-Shift-S to save them. The next time you fire up that game, it’ll remember what you set.
STEP 4: Tweaking your 3D experience.
All right, so you’ve got the game running great, the 3D effects are there, but maybe you still want to adjust the settings a little further. For instance, the 3D effect is a little more jarring in real-time strategy games like StarCraft II and MMO games because you have menus and cursors floating over the world out of perspective with the rest of the 3D depth. (Try selecting a target far downfield in an MMO and you’ll know what I’m talking about). There are all sorts of settings here that you can adjust. Experiment by adjusting the numbers for the “Depth” and “Focus” under the 3D menu. Under the “Options” and “Window and Cursor” sections, there are plenty of other toggles to switch on and off to your liking.
Goes without saying, make sure to hit Alt-Shift-S when you’re done and the Ignition software will remember all your preferences.
What About….?
Just so you know, this story is an on-going work-in-progress that I plan to update as I learn more. Here are a couple things that I’m currently looking into with the Envy 17 3D:
[This Game] Doesn’t Work at All / Is Glitchy in 3D. Yeah, I run into that problem as well every so often. DC Universe Online looks broken with tearing images when the 3D goggles are on. (Looks great in 2D, though). Other games, like Telltale Games’ new Back to the Future titles look five kinds of crazy. Those might be more specific fixes that require a deeper dive later on.
What about Flash-based games? My gut reaction is that the technology requires DirectX 9, 10 or 11 to work so this one might not be in the cards.
What about older games optimized for Windows 7? There are plenty of old-skool classics, I’d love to try in 3D, but they were all created in a pre-DirectX 9 world. That’s not stopping me from looking around for any solutions, but no word yet.
=-=-=-=-=-
So....was this even remotely helpful? Would you want to see more stuff like this? Or bits from stories I've written posted here? Heck, if there were topics you wanted tackled in story-form, I'm all ears for that as well.
Thanks in advance for any feedback!

             Charts,Cross-tabs and table information is coming from this Query
       2.Image count-contains number of images information based on the prompt selection and it acts as a
              URL(opendocument) in the report to open TDI_THUMBNAIL report to display the thumbnail images.
Report information
TDI_CHART Report contains 8 charts,4 cross-tabs, summary information showing in table format(Detail
       section) and2 open document links(1.For image count 2.Export to excel(which shows the detail information
        of summary table)
Description
If the selection is Non-Trend Value from the Time period parameter , corresponding Chart will be shown along   with table information.(Table information is only required for Non-Trend Values).
If the Selection is Trend Value from the Time period parameter,the corresponding cross tab and chart will be shown and others will get suppressed.
Problem Area
After the prompt selection from u201CDamage_Reportsu201D, TDI_CHART report is taking around 1min 30 sec to show the chart and table or cross-tab.
In Database when we execute the above queries, it comes in 12 secs but whereas in reports it takes 1min 30 sec,can you guide us some steps to bring down this time?

hello Mufiza,
copy the url created at the step "After the prompt selection from u201CDamage_Reports".
paste this url into a new browser window and press enter.
what is the time to return this report?...this time should also be 1.5 minutes.
it sounds like you are using 2 commands in the same report. this will often cause performance issues, just like linking two stored procedures together or linking two disparate datasources together.
this would not be an issue related to webelements but related to the design of your target report.

Performance issue while opening the report

HI,
I am working BO XI R3.1.there is performance issue while opening the report in BO Solris Server but on window server it is compratively fast.
we have few reports which contains 5 fixed prompt 7 optional prompt.
out of 5 fixed prompt 3 prompt is static (it contains 3 -4 record only )which is coming from materlied view.
we have already use many thing for improve performance in report like-
1) Index Awareness
2) Aggregate Awareness
3) Array fatch size-250
3) Aray bind time -32767
4) Login time out -600
the issue is that before refresh opening the report iteslf taking time 1.30 min on BO solris server but same report taking time in BO window server 45 sec. even we import on others BO solris server it is taking same time as per old solris server(1.30 min).
when we close the trace in solris server than it is taking 1.15 sec time.it should not be intial phase it is not hitting more on database.so why it is taking that much time while opening the report.
could you please guide us where exectly problem is there and how we can improve performance for opening the report.In case the problem related to solris server so what would be and how can we rectify.
Incase any further input require for the same feel free to ask me.

Hi Kumar,
If this is happening with all the reports then this issue seems to be due to firewall or security settings of Solaris OS.
Please try to lower down the security level in solaris and test for the issue.

Performance problems with external sounds and Sound class

I'm using Sound & SoundChannel classes to load and play external MP3s and I'm seeing terrible playback performance on my 3G phone. Audio starts out ok, but will gradually get more and more choppy and eventually crashes the app. The MP3s themselves are typical sizes, 2 - 6 MB and of various types (VBR, CBR).
On top of that, when the phone gets locked (with the app still running), the audio sputters and stops completely. When I unlock, it begins where it left off. Anyone else seeing this?
My code is pretty standard:
private var soundPlayer:Sound;
private var soundChannel:SoundChannel;
public function load(url:String, playNow:Boolean = true):void {
if (soundChannel) {
    soundChannel.stop();
soundPlayer = new Sound();
soundPlayer.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
soundPlayer.addEventListener(ProgressEvent.PROGRESS, onProgress);
soundPlayer.addEventListener(Event.ID3, onID3);
trace('Loading new stream: '+url);
var request:URLRequest = new URLRequest(url);
soundPlayer.load(request);
if (playNow) {
    this.isPlaying = true;
    soundChannel = soundPlayer.play();
    soundChannel.addEventListener(Event.SOUND_COMPLETE, onSoundComplete);

this is from another forum (http://discussions.info.apple.com/thread.jspa?threadID=2542931&tstart=0&messageID=12106188 ):
"I've spoken to the developers of of couple of these apps, and they've all said it's a memory fragmentation/low memory condition.
Restart the phone. Don't just turn it off and on, but restart it.
Hold the on/off button and the home button down like you were going to turn it off. When you see the swipe to turn off message, keep holding the buttons down.
In a few seconds the screen will flash, and then go dark.
Now it's really off.
Turn it back on (restarting it). All should be well.
The iPhone is really a computer. Performing a restart like this every once in a while (weekly, bi-weekly) is a good idea, esp if you use memory intensive apps."
