Performance boost question for G5 Dual 2.3 PPC

I have a late '05 PPC G5 that has been giving me fits so I bought a Jupiter 1TB 7200 RPM 32 MB Cache drive from OWC (to replace the oem 250 gb HD) along with 4-2 GB ram modules to replace the 8-512 MB modules that came with the computer. I have been unable to run Drive Genius to Verify, Rebuild or Defrag the oem 250 GB HD and Disk Warrior also failed to operate. OWC techs suspected bad ram... so I first installed the new 8GB ram modules and did a clean install of the original OS, Tiger, as my wide format Epson is not supported by Apple's later operating systems.
The old drive now appears to be perfect and both Drive Genius and Disk Warrior work... so bad ram must have been the issue.
With the old dive wiped clean and the new 1 TB drive to install, is there any point in keeping the oem 250 GB drive for scratch or anything else? It didn't get used much and I'm wondering if the old drive can be used to somehow boost the overall performance of the system?
Finally, since I use this computer for Aperture and Photoshop only, is there any point in installing the full 16 gb ram this G5 will accept or is this overkill for running Photoshop CS3 and Aperture 2?
Thanks for any advice!

Great news Lawrence, thanks!
I'll be working on files as large as 750 MB
Strange as it seems that'll likely require 4 times the RAM or VM for that, so 3GB just to edit that file!
wondering if there is any advantage to partitioning the 1TB hard drive and allocating a certain portion to scratch disk?
Not really, OSX is a strange beast, the more free disk space it has the better/smoother it runs... actually with one TB you might get away with Partitioning without slowing OSX, but you'd really gain nothing at all
Perhaps a Second really fast Drive like a WD Caviar Black in the other slot might help.
Can the HD be partitioned once Tiger has been installed (and before I install any software) or should this have been done before installing the OS?
Any Partitioning should be done first, & though I wouldn't bother doing it, it can be done after the fact...

I wanted to attempt to become self sufficient at these things as there won't always be a Mac technician or Apple Store nearby. Your guidance is much appreciated.
I'm certain you will, you pick up things rather well.. and there are tons of helpers here looking forward to easing your quest... so feel quite free to post a new query on whatever!
PS. Helping others here has learned me real good!

Samba Performance Boost for Samba on Freebsd

I had been struggling with various options in the smb.conf but failed to realize the operating system may be at fault for my slow (3.6m/sec) transfers. The following sysctl variable: "net.inet.tcp.inflight.enable" has solved my problem, more than doubling the throughput (wired network) to more than 7.5m/sec. Simply set this to 0 to disable it. It was originally designed for very fast networks with very little latency, like Gigabit, ATM, FDDI. For my simple 100mb/sec switch at home, this worked just awesome! Thanks to the Freebsd Performance Mailing list for the tips!!!

Disuye,
I've got a Mac Pro with LP 7.2.3 and OSX 10.5.2, and it runs pretty smoothly. I get the occasional core audio overload, but not enough to cause a concern.

8.0.2 and new ram, performance boost or waste of time?

Hi all,
I am going to add more ram to my MacBook. I understand that my MacBook officially only accepts of 2GB of ram (2x 1 gig sticks)I have read that many folks have put 4 gigs in a 2x2 gig matched pair configuration in there machine to get a maximum of 3 gigs. As I understand it this is not a supported configuration.
I don't mind paying for 4 gigs to only 3 my question is, would this make Logic unstable? I only use this machine for Logic and the apps that come with Logic Studio 1. I only go on line with it for updates and such so my main concern is keeping this machine stable for Logic.
Also I am imaging that increasing ram from 1 gig to even just the 2 that is officially supported will give me a bit of a performance boost but in what ways will I notice it in relation to Logics performance?
Also any recommendations for RAM in the UK would be very welcome.
Sorry for such a dull question,
Regards,
Jay

Hey Notefarm, a lot of my friends ( including myself and I noticed somebody else linked it here as well the other day ) use Crucial because of the macapp you can download which will tell you want you can have RAM wise and how much it's gonna cost you.

Performance Booster

Hi ,
We found a huge boost in the performance when we changed the reload period
for the web applications to "-1" ( which means never check for changes). The performane
actually improved 3 times.
My question is regarding the implications of this change. Will it cause any problems
which are not visible as of now? With this parameter setting , I will have to
probably restart the server everytime I modify the application...right? In the
case of our system, this web application is rarely going to change.
Are there any other issues that could occur?
Thanks in Advance
Amit

Reply to ensure that no one using WLS 6.0 sp1 or sp2, implements whats written
previously. DO NOT SET the reload parameter for web-applications to -1 in WLS
6.0 sp1 and sp2 . You will get an error. ITs a known problem.
The performance boost reported earlier was due to wrong observation.

If you are packaging your webapp's in .war format, you will have to restart

anyway, as we do not support hot deploy of webapps in 51. ( i presume
you are on 51)

I don't think you will encouter any issues by setting this property to

Eight questions for my N8

Hi,
I got my N8 two weeks ago and I LOVE IT!!!!
Here is a list of my questions for your expert advice:
Remote Lock. I had this option on my E66, how can I set it up on my N8?
Can I adjust the touch screen sensitivity?
Can I adjust the Scrolling Speed? The scrolling function in my Messages and my Notes is too sensitive and fast; If I try to tap-to-scroll, it just selects text for copying!
Is Swype available for our N8? I can’t find it on Ovi Store.
Is there a Font Magnifier software available for the N8? I’ve adjusted fonts to the largest, but they are still not large enough for my eyes.
On Ovi Maps, how can I repeat the Voice Guidance? In my E66, I think I would   press the 4 key, but how do I do it in our touch screen?
I’ve paired the N8 and can make calls in my Audi, but the Signal Strength bar, the Recent calls and more so the phone’s Contacts Directory are not shown on the car’s screen, what can I do?
I love watching on the TV, but I have found no way to play subtitle (.srt) files, or to adjust the screen size on the TV, with a Zoom or other function. Are those options available?

What drummer_tom is pointing to is the Dual Channel config for RAMs.
Slot 1 + 3 or Slot 2 + 4 or all 4 slots installed, will give you Dual Channel performance and capacity. A win-win situation.
As for the Blue and Purple Sata connectors, the 4 purple SATA connectors are controlled by Intel ICH9R chipset and the 1 blue SATA connector is controlled by Marvell controller. Only the Intel controlled SATA ports are able to RAID.

Increase Performance and ROI for SQL Server Environments

The Buzz from Microsoft Ignite 2015
NetApp was in full force at the recent Microsoft Ignite show in Chicago, talking about solutions for hybrid cloud, and our proven solutions for Microsoft SQL Server and other Microsoft applications.
Hot topics at the NetApp booth included:
OnCommand® Shift. A revolutionary technology that lets you move virtual machines back and forth between VMware and Hyper-V environments in minutes.
Azure Site Recovery to NetApp Private Storage. Replicate on-premises SAN-based applications to NPS for disaster recovery in the Azure cloud.
These tools give you greater flexibility for managing and protecting important business applications.
Chris Lemmons
Director, EIS Technical Marketing, NetApp
If your organization runs databases such as Microsoft SQL Server and Oracle DB, you probably know that these vendors primarily license their products on a "per-core" basis. Microsoft recently switched to "per-core" rather than "per-socket" licensing for SQL Server 2012 and 2014. This change can have a big impact on the total cost of operating a database, especially as core counts on new servers continue to climb. It turns out that the right storage infrastructure can drive down database costs, increase productivity, and put your infrastructure back in balance.
In many customer environments, NetApp has noticed that server CPU utilization is low—often on the order of just 20%. This is usually the result of I/O bottlenecks. Server cores have to sit and wait for I/O from hard disk drives (HDDs). We've been closely studying the impact of all-flash storage on SQL Server environments that use HDD-based storage systems. NetApp® All Flash FAS platform delivers world-class performance for SQL Server plus the storage efficiency, application integration, nondisruptive operations, and data protection of clustered Data ONTAP®, making it ideal for SQL Server environments.
Tests show that All Flash FAS can drive up IOPS and database server CPU utilization by as much as 4x. And with a 95% reduction in latency, you can achieve this level of performance with half as many servers. This reduces the number of servers you need and the number of cores you have to license, driving down costs by 50% or more and paying back your investment in flash in as little as six months.
Figure 1) NetApp All Flash FAS increases CPU utilization on your SQL Server database servers, lowering costs.

Whether you're running one of the newer versions of SQL Server or facing an upgrade of an earlier version, you can't afford not to take a second look at your storage environment.
End of Support for Microsoft SQL Server 2005 is Rapidly Approaching
Microsoft has set the end of extended support for SQL Server 2005 for April 2016—less than a year away. With support for Microsoft Windows 2003 ending in July 2015, time may already be running short.
If you're running Windows Server 2003, new server hardware is almost certainly needed when you upgrade SQL Server. Evaluate your server and storage options now to get costs under control.
Test Methodology
To test the impact of flash on SQL Server performance, we replaced a legacy HDD-based storage system with an All Flash FAS AFF8080 EX. The legacy system was configured with almost 150 HDDs, a typical configuration for HDD storage supporting SQL Server. The AFF8080 EX used just 48 SSDs.
Table 1) Components used in testing.

Source: NetApp, 2015
The test configuration consisted of 10 database servers connected through fibre channel to both the legacy storage system and the AFF8080 EX. Each of the 10 servers ran SQL Server 2014 Enterprise Edition.
The publicly available HammerDB workload generator was used to drive an OLTP-like workload simultaneously from each of the 10 database servers to storage. We first directed the workload to the legacy storage array to establish a baseline, increasing the load to the point where read latency consistently exceeded 20ms.
That workload was then directed at the AFF8080 EX. The change in storage resulted in an overall 20x reduction in read latency, a greater than 4x improvement in IOPS, and a greater than 4x improvement in database server CPU utilization.
Figure 2) NetApp All Flash FAS increases IOPS and server CPU utilization and lowers latency.
Source: NetApp, 2015
In other words, the database servers are able to process four times as many IOPS with dramatically lower latency. CPU utilization goes up accordingly because the servers are processing 4x the work per unit time.
The All Flash FAS system still had additional headroom under this load.
Calculating the Savings
Let's look at what this performance improvement means for the total cost of running SQL Server 2014 over a 3-year period. To do the analysis we used NetApp Realize, a storage modeling and financial analysis tool designed to help quantify the value of NetApp solutions and products. NetApp sales teams and partners use this tool to assist with return on investment (ROI) calculations.
The calculation includes the cost of the AFF8080 EX, eliminates the costs associated with the existing storage system, and cuts the total number of database servers from 10 to five. This reduces SQL Server licensing costs by 50%. The same workload was run with five servers and achieved the same results. ROI analysis is summarized in Table 2.

The takeaway here is that you can replace your existing storage with All Flash FAS and get a big performance bump while substantially reducing your costs, with the majority of the savings derived from the reduction in SQL Server licensing costs.
Replace your existing storage with All Flash FAS and get a big performance bump while substantially reducing your costs.
Maximum SQL Server 2014 Performance
In addition to the ROI analysis, we also measured the maximum performance of the AFF8080 EX with SQL Server 2014. A load-generation tool was used to simulate an industry-standard TPC-E OLTP workload against an SQL Server 2014 test configuration.
A two-node AFF8080 EX achieved a maximum throughput of 322K IOPS at just over 1ms latency. For all points other than the maximum load point, latency was consistently under 1ms and remained under 0.8ms up to 180K IOPS.
Data Reduction and Storage Efficiency
In addition to performance testing, we looked at the overall storage efficiency savings of our SQL Server database implementation. The degree of compression that can be achieved is dependent on the actual data that is written and stored in the database. For this environment, inline compression was effective. Deduplication, as is often the case in database environments, provided little additional storage savings and was not enabled.
For the test data used in the maximum performance test, we measured a compression ratio of 1.5:1. We also tested inline compression on a production SQL Server 2014 data set to further validate these results and saw a 1.8:1 compression ratio.
Space-efficient NetApp Snapshot® copies provide additional storage efficiency benefits for database environments. Unlike snapshot methods that use copy-on-write, there is no performance penalty; unlike full mirror copies, NetApp Snapshot copies use storage space sparingly. Snapshot copies only consume a small amount of storage space for metadata and additional incremental space is consumed as block-level changes occur. In a typical real-world SQL Server deployment on NetApp storage, database volume Snapshot copies are made every two hours.
First introduced more than 10 years ago, NetApp FlexClone® technology also plays an important role in SQL Server environments. Clones are fully writable, and, similar to Snapshot copies, only consume incremental storage capacity. With FlexClone, you can create as many copies of production data as you need for development and test, reporting, and so on. Cloning is a great way to support the development and test work needed when upgrading from an earlier version of SQL Server. You'll sometimes see these types of capabilities referred to as "copy data management."
A Better Way to Run Enterprise Applications
The performance benefits that all-flash storage can deliver for database environments are significant: more IOPS, lower latency, and an end to near-constant performance tuning.
If you think the performance acceleration that comes with all-flash storage is cost prohibitive, think again. All Flash FAS doesn't just deliver a performance boost, it changes the economics of your operations, paying for itself with thousands in savings on licensing and server costs. In terms of dollars per IOPS, All Flash FAS is extremely economical relative to HDD.
And, because All Flash FAS runs NetApp clustered Data ONTAP, it delivers the most complete environment to support SQL Server and all your enterprise applications with capabilities that include comprehensive storage efficiency, integrated data protection, and deep integration for your applications.
For complete details on this testing look for NetApp TR-4303, which will be available in a few weeks. Stay tuned to Tech OnTap for more information as NetApp continues to run benchmarks with important server workloads including Oracle DB and server virtualization.

Please answer a programming question for an admin

I'm not a programmer (although my interest is growing), so I can't answer this question in a discussion regarding how Win32API w/OLE and COM is SO much better than programming for Unix/OS X applications.
The original discussion was in regards to OS X's superior Unix based security, he devolved to this. Having only begun my venture into programming, his questions are a little above my head at this point. I'm also interested (as an amature programmer), how this would be accomplished in OS X/Unix.
Thanks in advance.
Here's his position:
*(1st entry)*
I have unsed Windows and many flavors of Unix and I have written programs in Assembler, Fortran, Pascal, Cobol, RPG, Smalltak, Basic, PowerBuilder, Delphi, C, C++, C#, Java, and Perl, and I have been programming for over 20 years, so I do have extensive knowledge about programming.
So I have one question for you:
If you had to build a business application that has to allow users to, spell and grammer check, and perform financial calculations, and render the HTML, how would you compare the effort to do this in Windows versus that in Linux, AIX, Solaris or any other Unix operating system?
I can make this business application have these features in ONE DAY on Windows, because COM and OLE lets me, use Word to spell and grammer check, Excel to do the financial calculations, and IE to render the HTML!
I make my living building complex customized business software, and Windows allow me to build these applications by myself in weeks, when it would take me and a team of programmers months to do these same things in Unix because of the lack of an the Win32 API, COM, and OLE, or I would have to BUY third party libraries that did these things, and deal with the licensing, versioning, and vendor problems that go with them, and none of those third party librabries would be close to Word, Excel, and IE in CAPABILITY!
HONESTLY tell me and others reading this thread how you would go about create the customized business application I described above by yourself in a Unix instead of Windows, and tell us how many MONTHS or YEARS it would take you, or how you would have to BUY some other third party libraries to do what Word, Excel, and IE!
Anyone who thinks a Unix has more CAPABILITIES than Windows, has never used Win32API/COM/OLE/.Net, and does not build customized complex business software for a living, because we people that do are the reason that you find some much customized business desktop software for Windows, and so little for any Unix.
I have nothing against Unix, and it is great for simple business tasked server software, but for complex business tasked desktop software Windows with Win32API/COM/OLE/.Net wins hands down!
*(2nd Entry)*
A System administrators view of an operating system and an application developers view are entirely different, and the Win32API/COM/OLE/.NET simply make my job so much easier, and you simply don't understand because you do not have to deal with the "dirty' details of making what a user wants, which is why your definition of "integration" and mines are totally different!
With the spell check you talked about, how will you keep in in synch with the dictionary in Word where the user is constantly adding and removing words?
No, you would have the user to have to maintain two different spell check dictionaries, and you would totally ignore the grammer check requirement!
Cutting and pasting data between applications is simple integration, and not the complex type that I am talking about.
Can you make your application display and use the MacGourmet menus appear in its own window, and to access and use the MacGourmet functionality (ie. search for a recipe) in its own window?
Give me one example of a Unix application that can display the menus of another application, yet alone control its features!
Of course you can't, because you need COM and OLE!
I am quite familiar with different flavors of Unix, but those operating systems do not have the rich API and program integration features namely COM and OLE that Windows has, because it violates the Unix idea of security by process isolation!
Yes that idea of process isolation keeps the operating system safe from malicious code in applications and from one application taking the others down, but you lose the power of programs working together, and you simply cannot build the type of customized business applications that I build by myself, without reinventing the wheel over and over and without having a large team with lots of programmers.
For example, my customers and millions of others spend all day working in Word and Excel, and the Windows idea that I can transparently integrate my complex business applications right in Word and Excel menu, and into their templates and macros, is why third party developers like me prefer Windows over Unix, regardless of how much better security in Unix is.
Do not get me wrong, Java improves business application development on Unix, but unfortuantely it is not feasable to rewrite ever legacy application in Java, and Java does not integrate well with other programming languages.
I used to code business application for both IBM MVS and Sun Solaris, and I never want to go back to those "bad" old days again, once I took the time to learn how to PROPERLY code using Win32API/COM/OLE/.NET!

At risk of feeding the troll I'll wander in here:
NOTE: Since this is an Apple programming boards and I have limited experience programming on traditional Unix systems (and most of that in college) I will confine my answers to the area I know.
If you had to build a business application that has to allow users to, spell and grammer check, and perform financial calculations, and render the HTML, how would you compare the effort to do this in Windows versus that in Linux, AIX, Solaris or any other Unix operating system?
I can make this business application have these features in ONE DAY on Windows, because COM and OLE lets me, use Word to spell and grammer check, Excel to do the financial calculations, and IE to render the HTML!
Note that this scenario assumes the user has Microsoft office installed. The person argues that they don't have to purchase libraries to program but what they are effectively doing is simply transferring that cost to user. I don't have to purchase libraries but everyone of my users needs to. Good for you, very good for Microsoft but bad for your customer - IMHO. OK, I know "But all Windows business users have Office installed already." When it comes free with the system then I'll retract my objection.
Under OS X and Cocoa many of these functions are intrinsic to the system layer and do not require any applications to be installed. Using Cocoa you can write a simple Word processor that has rulers, full font manipulation (including kerning, spacing and leading), Document Save and Load, Printing, Export to PDF as well as spell-checking in under 10 lines of actual code. Adding a custom file type and icon for full system integration will add another 5 minutes to your programing.
In case you think I'm blowing smoke here is a tutorial from 2002 (yes, this has been possible for over 5 years) outlining the 8 line Word Processor build in Cocoa. http://www.stone.com/TheCocoa_Files/What_s_sofunny.html
And yes, Cocoa also includes Webkit so I can add full HTML rendering by dragging in a WebKit window to my user interface. For an experienced Cocoa programmer this certainly sounds like less than a day of programming - in fact it sounds like a good tutorial for a middle-experienced training day or 2 day class in Cocoa.
I won't include the link to the 1 line web browser you can build in Cocoa using Webkit because it's shorter than the description. Feel free to search for it if you want to.
HONESTLY tell me and others reading this thread how you would go about create the customized business application I described above by yourself in a Unix instead of Windows, and tell us how many MONTHS or YEARS it would take you, or how you would have to BUY some other third party libraries to do what Word, Excel, and IE!
BUT this is all done from the stock system that is on every OS X computer not simply those with Office installed. Obviously you'd need to add some features that were more complicated than this - because any halfway decent programmer could turn this stuff out - and polish takes a while but to meet the requirements of the challenge it would take 2 days tops.
Is every *nix programming environment like this? I don't know I can only answer for the system that I have experience with and is the concern of this board. If you really have questions regarding *nix programming then I suggest you find an appropriate board and troll^H^H^H^H^H ask there.
If you're ever serious about programming on the Mac feel free to stop by and actually take a look at it. I think you'll be surprised.

Some dvi questions for those who really know there stuff!

Hi all, haven't lurked these forums in a few weeks but just had a quick question for those who wanna build up some "points". I'm trying to connect my MBP 15" (1.83ghz) to my Dell LCD 26" T.V. via DVI. Anyhoo, the DVI port on an MBP is a DVI-I (Dual link 24 + 5 pin) fenmale port while my Dell LCD sports a DVI-D (Dual link 24 + 1 pin) female port. Anyhoo, I went to my local Circuit City store and picked up a 6.6ft DVI-D (Single link 18 + 1 pin) male cable to hook both devices up. Should this work? If those have no idea what I'm talking about, I've included a link with a picture of allt he different DVI ports:
http://upload.wikimedia.org/wikipedia/commons/thumb/5/59/Dvitypes.png/180px-Dvitypes.png
If I haven't explained myself well, please post and I'll do my best to clarify.

Am I missing something? Do you actually have a problem making this work? If the plugs you chose are mechanically compatible (and both are DVI D, dual-link), then there should not be a problem.
Ah. I see the concern. The extra four pins. I believe they make the connector able to supply hybrid DVI-A and DVI-D. The Mac output is hybrid so it can easily be adapted drive a VGA monitor, too.
I think you should be fine.
I have a ViewSonic 1600x1200 LCD monitor with a DVI (single) and it works superbly with the Mac.

Is there a big performance boost from 2008 MacBook Pro to i7 iMac/Mac Pro?

I'm trying to determine if a new desktop is worth the investment. I have a 2008 MacBook Pro, 2.4 GHz and 4GB of RAM. I'm getting a little frustrated with it when using it with Aperture and Final Cut Express. It's just too sluggish for me.
But before I drop about $2500 on a new Mac Pro or iMac, I want to be sure I'm going to see a huge performance boost over my laptop. I'd hate to spend all the money only to find my photos and videos process only 10 or 15% faster than before. I'd like to see a new machine perform twice as fast but maybe that's unrealistic. I'm just not sure.
Can someone please tell me what I should expect? Thanks.

Hi,
Barefeats has done all sorts of tests http://www.barefeats.com/
Maybe these two http://www.barefeats.com/mbpp20.html http://www.barefeats.com/mbpp18.html can give an impression on what to expect (i7 iMac - MBP 3.06 C2D)
Hope it helps

Performance Tuning Certification for Application Developer

Hi,
Can you please advise if there is any Oracle Performance Tuning certification for an Application Developer and Oracle 9i to 10G migration certification? If yes, can you please let me know its Oracle examination number?
I have already passed 1Z0-007 and 1Z0-147 in Oct 2008.
Thanks in advance,
Sandeep Kumar

... if there is any Oracle Performance Tuning certification for an Application Developer ...There is no performance tuning related certification for application developers. There is one for the DBA track.
Also -- to answer your question in the other thread:
So to clear this certification do I need to re-appear all the 3 exams as they were given in 2008 or just 1Z0-146 is enough.Having passed 1Z0-007 and 1Z0-147, if you pass 1Z0-046, you will gain the certification: Oracle Advanced PL/SQL Developer Certified Professional

Questions for Integration

Hello,
Our VoIP Architect recently left the company as well as his knowledge and I'm just a data guy :-(. We are preparing to perform an integration for a new acquisition and out-sourcing was not considered prior to his leaving, plus funds may not be available to outsource. We will not be integrating there PBX into the infrastructure as we will be providing them IPT services.
My question to the forum is: what questions should we be asking to perform the integration with regards to VoIP.
1) What type of dial plan do they have
2) They will want to keep there DID so a port is needed with local PRI
3) I believe long distance will be provided through corporate
4) Do they have a night attendant
Any assistance is appreciated. Thanks
Anthony

Hello Anthony,
So you have the honor to learn VoIP on the fast track!? Well then let´s see the options.
First your questions are not bad, but only a small portion of the whole picture. The underlying question is: What functionality does telephony offer them now?The second question will be what are you able to reproduce with voip, what will be missing and what will be added.
About a few parts of functionality now:
- Availability (power, network, fallback scenario,...)
- Dial plan
- Voice mail
- 911
- call waiting/redirect/conference/...
- secretary function (rings ith boss phone)
- etc.
Now this is a lot of stuff to think about. So you can take everything at CCO that a search for "SRND voice" delivers you. SRND = Solution Reference Network Design, this is what you are asking for.
And doing this will show you that there is a lot more to tell than I could possibly write in a single post.
Another starting point would be "CISCO IP TELEPHONY SOLUTION" http://www.cisco.com/en/US/netsol/ns340/ns394/ns165/ns268/networking_solutions_package.html
Being a Global Knowledge Technical Instructor I would also like to point you to our Web page, where you can find the officil Cisco classes about IPT:
http://www.globalknowledge.com/training/category.asp?pageid=9&methodid=c&catid=206&country=United+States&translation=English
When you are interested in design then you could start with "IPTD (IP Telephony Design)"
http://www.globalknowledge.com/training/course.asp?pageid=9&courseid=9124&catid=206&methodid=c&country=United+States&translation=English
The other classes are more technology oriented and provide also hands-on to real euquipment.
Hope this helps! Please rate all helpful posts

ESH_ADM_INDEX_ALL_SC cannot perform initial indexing for all search connectors

Dear SAP Gurus,
We are implementing TREX version 7.10.50 for Talent Management ECC 6.0 - EHP 5.
I'd like to ask you question regarding ESH_ADM_INDEX_ALL_SC program
which used to create search connector for TREX and perform initial indexing for all search connectors.
As we know we can perform indexing using ESH_COCKPIT transaction code or use ESH_ADM_INDEX_ALL_SC.
If I try to perform indexing using ESH_COCKPIT, all search connectors can be indexed ("searchable" column are "checked" and status are changed to "Active" for all search connectors).
However, if I try to perform indexing using ESH_ADM_INDEX_ALL_SC, not all search connectors are indexed.
I've traced the program ESH_ADM_INDEX_ALL_SC using ST01 transaction code and found these error:
- rscpe__error 32 at rscpu86r.c(6;742) "dest buffer overflow" (,)
- rscpe__error 32 at rscpc (20;12129) "convert output buffer overflow"
- rscpe__error 128 at rstss01 (1;178) "Object not found"
Please kindly help me to solve this issue,
Thank you very much
Regards,
Bobbi

Where to perform date conversion for display?

Hi,
We have started our application with operation for single country, all data located in single database. The transaction history time stored is all in GMT+8.
However, with business expansion, we now have to cater for multiple country that is of different timezone. I need to display the transaction history in local time to the user of the different timezone.
Gut feel says i should continue to store all the time in a single timezone (i.e. probably GMT+8 for my case). And perform conversion during for the display.
Question is where should i be doing this? I am using Struts for web tier, EJB and Mysql. Based on MVC pattern, it seems that this should be done in Struts layer (probably DispatchAction).
Any recommended pattern? Any idea how to handle daylight saving?

Yes, you should store all your timestamps in the same timezone. And it would be best if your database server uses the same timezone as your application server, otherwise you could run into problems.
Now, the java.util.Date object and its SQL relative java.sql.Timestamp consist only of a single number, which is the number of milliseconds since a certain point in time. Normally they are what you get from the database. The thing to remember about them is that they do not have a timezone. As you suspect, displaying them applies a timezone to them. If the displaying is done by SimpleDateFormat -- which it should be, whether you do it in code or Struts does it -- you just need to make sure that the SimpleDateFormat has been assigned the correct timezone. This takes care of daylight savings time as well.
Finding out what timezone your users are in may be more tricky than you expect, but this depends on where they are located. You can't necessarily derive a timezone from a country, so you may have to ask the user what their timezone is.

Impulse trigger to create a time delay of x ms to perform an action for y ms

Hello all,
Here is what i'm trying to do:
I'm measuring an audio signal when a sound level is above a certain value Y (controllable) i need to wait a few ms (around 900ms) to get pass the main sound compound. Yhen i need to filter the next few ms (around 500ms) of data and do a FFT of that part of the filtered data only once until Y is reached again.
I can do all this with saved data but i'm struggling to do it as it occurs without saving the data.
I have everything in place i just need to know in general how to use an impulse trigger to a create time delay of x ms to perform an action for y ms.
Do you have any ideas how i can achieve this?
Thank you in advance,
Frederic.

Hi Frederic,
I've looked at your program and I have a few questions. What is the purpose of the Two While Loops that simply have a Case Structure that nothing in the false case and a Wait (ms) function in the true case? As it stands if these loops go into the false case then there is nothing to slow down the execution so the will try to run as fast as possible and not give the processor any time for other tasks which may explain why your computer goes so slow whilst this is running. This also applies to the While Loop where the false case says "If its not time to write the measurement file, do nothing."
I believe that what you want to look at is a Producer/Consumer(data) Pattern, where you have one loop that generates your data (producer), in this case reads in the sound data, and then a processing loop (consumer) that will do the Fat's and log data to a file etc.
More information about this can be found here: http://zone.ni.com/devzone/cda/tut/p/id/3023
Hopefully this helps you a bit. Let me know any questions you have.
