  • Working with Sub-Optimal Disk Configurations (Making the best of what you’ve got)

    - by Jonathan Kehayias
    This is the first post in a what will be a series of posts on working with a sub-optimal disk configuration to squeeze as much performance out of it as possible.  You might ask what a Sub-Optimal Disk Configuration?  In this case it is a Dell Powervault MD3000 with 15 Seagate Barracuda ES.2 SAS 1 TB 7.2K RPM disks (Model Number ST31000640SS).  This equates to just under 14TB of raw storage that can configured into a number of RAID configurations.  In this case, the disk array...(read more)

  • New PeopleTools Developer Book Available

    - by matthew.haavisto
    I recently had an opportunity to work through a copy of a new book for PeopleTools developers and thought it might be of interest to the readers of the PeopleTools blog. It is called PeopleSoft PeopleTools Tips & Techniques, and was written by Jim Marion, a long-time Oracle employee we often recruit to deliver the very popular and highly regarded conference sessions of the same title. This book is not for the beginner and doesn't contain much introductory material. Instead, it's for the more experienced PeopleSoft developer looking to maximize the efficiency and productivity of their PeopleSoft applications. Throughout the book Jim offers proven methods and best practices he's worked with personally. PeopleSoft PeopleTools Tips & Techniques lays out the benefits of many tactics along with implementation considerations, programming instructions, and reusable code samples. It will help you construct powerful iScripts, build custom UIs, work with Java and Ajax, and integrate the latest Web 2.0 features. Test-driven development, application security, performance tuning, and debugging are also covered in this authoritative resource. This book was one of the best sellers at the Oracle bookstore during the most recent Oracle Open World conference. The book can be ordered here and here. You may also want to check out Jim's PeopleTools developer blog.

  • Running & Managing Concurrent Queries in SQL Developer

    - by thatjeffsmith
    We’ve all been there – you’ve managed to write a query that takes longer than a few seconds to execute. Tuning aside, sometimes it takes longer than you want for a query to run. So what’s a SQL Developer user to do? I say, keep going! While you’re waiting for your query to finish, there’s no reason why you can’t continue on with your work. If you need to execute something else in a worksheet, there’s no reason to launch a 2nd or 3rd copy of SQL Developer. Just open an un-shared worksheet. Now while you’ve got 1 or more queries running, you can easily get yourself into a situation where you’re not sure what’s running where. Or maybe you want to cancel a query or just check how long something’s been running. Just open the Task Progress Panel If a query or task in SQL Developer takes more than 3-5 seconds, it will appear in the Task Progress panel. You can then watch the throbbers go back and forth while you sip your coffee/soda/Red Bull. Run a query, spawn a new worksheet, run another query, watch them in the Task Progress panel. Kudos and thanks to @leight0nn for helping me get the title of this post right If you’re looking for help in managing and monitoring sessions in general, check out this post.

  • Client Centric Approach of AJAX using Toolkit

    In this article, the author discusses the client-centric approach for AJAX using the ASP.NET AJAX Toolkit. In general, server-centric (use of Update panel) is very popular in this field. But when it comes to performance, the client-centric approach is preferred. Sandeep also demonstrates how to call a webservice using javascript.

  • IDC Analyst Report Touts Oracle–Accenture Strategic Initiative

    - by kristin.jellison
    Hi there, partners! Oracle Engineered Systems have been getting some love lately, and we want to share it with you! The market intelligence and advisory firm IDC recently released a report lauding Oracle and Accenture’s strategic initiative to route the performance and flexibility of Oracle Engineered Systems to clients. The report, "Oracle and Accenture Strategic Alliance Places Big Bet on Engineered Systems,” by Steve White, reflects a largely positive analysis of the relationship. White notes that the alliance is “one of the largest in the industry.” Under the relationship, Accenture has incorporated Oracle Engineered Systems—including Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud, Oracle SuperCluster, and Oracle Exalytics In-Memory Machine—into its leading datacenter transformation consulting services. Together, the two companies have also created bespoke platforms, such as the Accenture Foundation Platform for Oracle, which helps clients accelerate deployments on Oracle Fusion Middleware, running Oracle Exalogic Elastic Cloud and Oracle Exadata Database Machine. Oracle Engineered Systems deliver a single, engineered platform—including server to storage and networking. This makes it easier and cheaper for Accenture clients around the world to prepare their datacenters for managing, processing and analyzing the massive amounts of data they (rightly) anticipate seeing in the next decade. The new solutions can help reduce the effort and cost to migrate any vendor database to an Oracle Engineered Systems platform, which can lower the cost of ownership by up to 50 percent. For its part, Accenture has built a team of 300 consultants to implement and increase the flexibility and stability of client datacenters. This move further expands one of the fastest-growing full-service Oracle Enterprise solutions. Over 52,000 Accenture consultants are qualified to implement, upgrade and outsource the Oracle product suite. Accenture is a Diamond-level member of Oracle PartnerNetwork (OPN). For Oracle Partners, this update should give you at least two things to walk away with. First, this initiative is showing signs of success. As Marty Cole, group chief executive for Accenture’s Technology growth platform, put it, “We are seeing an increasing number of clients recognizing the value of consolidating their databases and taking advantage of the cost and performance benefits delivered by these solutions.” The pipeline is there—and not just for Accenture. Use this example to show your clients that investments in Oracle Engineered Systems are on the rise. Second, recognize that Oracle Engineered Systems represent one of the biggest platforms for growth that Oracle has to offer partners. As part of the agreement, Accenture is able to provide: Platform Readiness Assessments Platform Implementation App Rationalization Database Rationalization Managed Services These are all enablement opportunities you can offer customers under Oracle’s partner programs —to continue building the value of their investments, and the value of your relationship with Oracle. Take a read through the IDC report. To learn more about the partnership, see this press release. Happy selling! The OPN Communications Team

  • T-SQL Tuesday 24: Ode to Composable Code

    - by merrillaldrich
    I love the T-SQL Tuesday tradition, started by Adam Machanic and hosted this month by Brad Shulz . I am a little pressed for time this month, so today’s post is a short ode to how I love saving time with Composable Code in SQL. Composability is one of the very best features of SQL, but sometimes gets picked on due to both real and imaginary performance worries. I like to pick composable solutions when I can, while keeping the perf issues in mind, because they are just so handy and eliminate so much...(read more)

  • J2EE Applications, SPARC T4, Solaris Containers, and Resource Pools

    - by user12620111
    I've obtained a substantial performance improvement on a SPARC T4-2 Server running a J2EE Application Server Cluster by deploying the cluster members into Oracle Solaris Containers and binding those containers to cores of the SPARC T4 Processor. This is not a surprising result, in fact, it is consistent with other results that are available on the Internet. See the "references", below, for some examples. Nonetheless, here is a summary of my configuration and results. (1.0) Before deploying a J2EE Application Server Cluster into a virtualized environment, many decisions need to be made. I'm not claiming that all of the decisions that I have a made will work well for every environment. In fact, I'm not even claiming that all of the decisions are the best possible for my environment. I'm only claiming that of the small sample of configurations that I've tested, this is the one that is working best for me. Here are some of the decisions that needed to be made: (1.1) Which virtualization option? There are several virtualization options and isolation levels that are available. Options include: Hard partitions:  Dynamic Domains on Sun SPARC Enterprise M-Series Servers Hypervisor based virtualization such as Oracle VM Server for SPARC (LDOMs) on SPARC T-Series Servers OS Virtualization using Oracle Solaris Containers Resource management tools in the Oracle Solaris OS to control the amount of resources an application receives, such as CPU cycles, physical memory, and network bandwidth. Oracle Solaris Containers provide the right level of isolation and flexibility for my environment. To borrow some words from my friends in marketing, "The SPARC T4 processor leverages the unique, no-cost virtualization capabilities of Oracle Solaris Zones"  (1.2) How to associate Oracle Solaris Containers with resources? There are several options available to associate containers with resources, including (a) resource pool association (b) dedicated-cpu resources and (c) capped-cpu resources. I chose to create resource pools and associate them with the containers because I wanted explicit control over the cores and virtual processors.  (1.3) Cluster Topology? Is it best to deploy (a) multiple application servers on one node, (b) one application server on multiple nodes, or (c) multiple application servers on multiple nodes? After a few quick tests, it appears that one application server per Oracle Solaris Container is a good solution. (1.4) Number of cluster members to deploy? I chose to deploy four big 64-bit application servers. I would like go back a test many 32-bit application servers, but that is left for another day. (2.0) Configuration tested. (2.1) I was using a SPARC T4-2 Server which has 2 CPU and 128 virtual processors. To understand the physical layout of the hardware on Solaris 10, I used the OpenSolaris psrinfo perl script available at http://hub.opensolaris.org/bin/download/Community+Group+performance/files/psrinfo.pl: test# ./psrinfo.pl -pv The physical processor has 8 cores and 64 virtual processors (0-63) The core has 8 virtual processors (0-7)   The core has 8 virtual processors (8-15)   The core has 8 virtual processors (16-23)   The core has 8 virtual processors (24-31)   The core has 8 virtual processors (32-39)   The core has 8 virtual processors (40-47)   The core has 8 virtual processors (48-55)   The core has 8 virtual processors (56-63)     SPARC-T4 (chipid 0, clock 2848 MHz) The physical processor has 8 cores and 64 virtual processors (64-127)   The core has 8 virtual processors (64-71)   The core has 8 virtual processors (72-79)   The core has 8 virtual processors (80-87)   The core has 8 virtual processors (88-95)   The core has 8 virtual processors (96-103)   The core has 8 virtual processors (104-111)   The core has 8 virtual processors (112-119)   The core has 8 virtual processors (120-127)     SPARC-T4 (chipid 1, clock 2848 MHz) (2.2) The "before" test: without processor binding. I started with a 4-member cluster deployed into 4 Oracle Solaris Containers. Each container used a unique gigabit Ethernet port for HTTP traffic. The containers shared a 10 gigabit Ethernet port for JDBC traffic. (2.3) The "after" test: with processor binding. I ran one application server in the Global Zone and another application server in each of the three non-global zones (NGZ):  (3.0) Configuration steps. The following steps need to be repeated for all three Oracle Solaris Containers. (3.1) Stop AppServers from the BUI. (3.2) Stop the NGZ. test# ssh test-z2 init 5 (3.3) Enable resource pools: test# svcadm enable pools (3.4) Create the resource pool: test# poolcfg -dc 'create pool pool-test-z2' (3.5) Create the processor set: test# poolcfg -dc 'create pset pset-test-z2' (3.6) Specify the maximum number of CPU's that may be addd to the processor set: test# poolcfg -dc 'modify pset pset-test-z2 (uint pset.max=32)' (3.7) bash syntax to add Virtual CPUs to the processor set: test# (( i = 64 )); while (( i < 96 )); do poolcfg -dc "transfer to pset pset-test-z2 (cpu $i)"; (( i = i + 1 )) ; done (3.8) Associate the resource pool with the processor set: test# poolcfg -dc 'associate pool pool-test-z2 (pset pset-test-z2)' (3.9) Tell the zone to use the resource pool that has been created: test# zonecfg -z test-z1 set pool=pool-test-z2 (3.10) Boot the Oracle Solaris Container test# zoneadm -z test-z2 boot (3.11) Save the configuration to /etc/pooladm.conf test# pooladm -s (4.0) Results. Using the resource pools improves both throughput and response time: (5.0) References: System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones Capitalizing on large numbers of processors with WebSphere Portal on Solaris WebSphere Application Server and T5440 (Dileep Kumar's Weblog)  http://www.brendangregg.com/zones.html Reuters Market Data System, RMDS 6 Multiple Instances (Consolidated), Performance Test Results in Solaris, Containers/Zones Environment on Sun Blade X6270 by Amjad Khan, 2009.

  • Cross-platform independent development

    - by Joe Wreschnig
    Some years ago, if you wrote in C and some subset of C++ and used a sufficient number of platform abstractions (via SDL or whatever), you could run on every platform an indie could get on - Linux, Windows, Mac OS of various versions, obscure stuff like BeOS, and the open consoles like the GP2X and post-death Dreamcast. If you got a contract for a closed platform at some point, you could port your game to that platform with "minimal" code changes as well. Today, indie developers must use XNA to get on the Xbox 360 (and upcoming Windows phone); must not use XNA to work anywhere else but Windows; until recently had to use Java on Android; Flash doesn't run on phones, HTML5 doesn't work on IE. Unlike e.g. DirectX vs. OpenGL or Windows vs. Unix, these are changes to the core language you write your code in and can't be papered over without, basically, writing a compiler. You can move some game logic into scripts and include an interpreter - except when you can't, because the iPhone SDK doesn't allow it, and performance suffers because no one allows JIT. So what can you do if you want a really cross-platform portable game, or even just a significant body of engine and logic code? Is this not a problem because the platforms have fundamentally diverged - it's just plain not worthwhile to try to target both an iPhone and the Xbox 360 with any shared code because such a game would be bad? (I find this very unlikely. I can easily see wanting to share a game between a Windows Mobile phone and an Android, or an Xbox 360 and an iPad.) Are interfaces so high-level now that porting time is negligible? (I might believe this for business applications, but not for games with strict performance requirements.) Is this going to become more pronounced in the future? Is the split going to be, somewhat scarily, still down vendor lines? Will we all rely on high-level middleware like Flash or Unity to get anything cross-platform done? tl;dr - Is porting a problem, is it going to be a bigger problem in the future, and if so how do we solve it?

  • How to pause/resume transfer of large files?

    - by Olivier Lalonde
    I recently had to copy about 20 GB of data split between about 20 files from my laptop to an external hard drive. Since this operation takes quite a while (at ~560kb/s), I was wondering if there was any way to pause the transfer and resume it later (in case, I need to interrupt the transfer). As a side question, is there any performance difference between copying from the terminal vs copying from Nautilus?

  • Monitoring Your Servers

    - by Grant Fritchey
    If you are the DBA in a large scale enterprise, you’re probably already monitoring your servers for up-time and performance. But if you work for a medium-sized business, a small shop, or even a one-man operation, chances are pretty good that you’re not doing that sort of monitoring. You know that you’re supposed to be doing it, but other things, more important at-the-moment things, keep getting in the way. After all, which is more important, some monitoring or backup testing?  Backup testing, of course. Monitoring is frequently one of those things that you do when can get around to it.  Well, as you can see at the right, I have your round tuit ready to go. What if I told you that you could get monitoring on your servers for up-time, job completion, performance, all the standard stuff? And what if I told you that you wouldn’t need to install and configure another server in your environment to get it done? And what if I told you that you’d be able to set up and customize your alerts so you could know if your server was offline or a drive was full? Almost nothing for you to do, and you’ll have a full-blown monitoring process. Sounds to good to be true doesn’t it? Well, it’s coming. We’re creating an online, remote, monitoring system here at Red Gate. You’ll be able to use our SQL Monitor tool (which you can see here, monitoring SQL Server Central in real time) to keep track of your systems, but without having to set up a server and a database for storing the information collected. Instead, we’re taking advantage of services available through the internet to enable collection and storage of this information remotely, off your systems. All you have to do is install a piece of software that will communicate between our service and your servers and you’ll be off and running. It’s that easy.
