  • Do you really need cable management for a cabinet with just switches and patch panels?

    - by ObligatoryMoniker
    We are about to start wiring out a building expansion and our vendor has laid out the racks in the following configuration: Option 1 1U Fiber patch panel 2U Cable Manager 2U 48 port Patch Panel 2U Cable Manager 2U 48 port Patch Panel 2U Cable Manager 1U 48 port Switch 2U Cable Manager 1U 48 port Switch Total = 15U All the patch panels would be connected to the switches with 1ft+ cables fed through cable management. What I am considering instead is: Option 2 1U Fiber patch panel 1U 24 port Patch Panel 1U 48 port Switch 2U 48 port Patch Panel 1U 48 port Switch 2U 48 port Patch Panel Total = 8U All of the patch panels would be connected to the switches with .5 ft cables directly on their face with the top 24 ports of each switch patched to the patch panel above it and the bottom 24 ports of each switch patched to the patch panel beneath it which would not require any cable management. If I go with option 2 it save all of the space used by cable management and allows us to keep adding on switches and patch panels at the end without having to re-cable all of the patch panels above. Our vendor has indicated that this is not best practice and that .5ft cables will introduce cross talk. I could understand that being the case if we were connecting the .5 ft cable directly into another switch but we are connecting it to a patch panel that likely has another 150 ft cable run from the back of the patch panel out to the port in the building in which case the real resulting cable is 150.5 ft at minimum before even connecting it to a PC. It seems like it makes much more sense to go with option 2. It is easier to expand, saves space, and saves money on cabling and cable management. Does this kind of configuration make sense or is there a legitimate reason to choose Option 1 over Option 2?

  • Stumbling Through: Making a case for the K2 Case Management Framework

    I have recently attended a three-day training session on K2s Case Management Framework (CMF), a free framework built on top of K2s blackpearl workflow product, and I have come away with several different impressions for some of the different aspects of the framework.  Before we get into the details, what is the Case Management Framework?  It is essentially a suite of tools that, when used together, solve many common workflow scenarios.  The tool has been developed over time by K2 consultants that have realized they tend to solve the same problems over and over for various clients, so they attempted to package all of those common solutions into one framework.  Most of these common problems involve workflow process that arent necessarily direct and would tend to be difficult to model.  Such solutions could be achieved in blackpearl alone, but the workflows would be complex and difficult to follow and maintain over time.  CMF attempts to simplify such scenarios not so much by black-boxing the workflow processes, but by providing different points of entry to the processes allowing them to be simpler, moving the complexity to a middle layer.  It is not a solution in and of itself, development is still required to tie the pieces together. CMF is under continuous development, both a plus and a minus in that bugs are fixed quickly and features added regularly, but it may be difficult to know which versions are the most stable.  CMF is not an officially supported K2 product, which means you will not get technical support but you will get access to the source code. The example given of a business process that would fit well into CMF is that of a file cabinet, where each folder in said file cabinet is a case that contains all of the data associated with one complaint/customer/incident/etc. and various users can access that case at any time and take one of a set of pre-determined actions on it.  When I was given that example, my first thought was that any workflow I have ever developed in the past could be made to fit this model there must be more than just this model to help decide if CMF is the right solution.  As the training went on, we learned that one of the key features of CMF is SharePoint integration as each case gets a SharePoint site created for it, and there are a number of excellent web parts that can be used to design a portal for users to get at all the information on their cases.  While CMF does not require SharePoint, without it you will be missing out on a huge portion of functionality that CMF offers.  My opinion is that without SharePoint integration, you may as well write your workflows and other components the old fashioned way. When I heard that each case gets its own SharePoint site created for it, warning bells immediately went off in my head as I felt that depending on the data load, a CMF enabled solution could quickly overwhelm SharePoint with thousands of sites so we have yet another deciding factor for CMF:  Just how many cases will your solution be creating?  While it is not necessary to use the site-per-case model, it is one of the more useful parts of the framework.  Without it, you are losing a big chunk of what CMF has to offer. When it comes to developing on top of the Case Management Framework, it becomes a matter of configuring what makes up a case, what can be done to a case, where each action on a case should take the user, and then typing up actions to case statuses.  This last step is one that I immediately warmed up to, as just about every workflow Ive designed in the past needed some sort of mapping table to set the status of a work item based on the action being taken definitely one of those common solutions that it is good to see rolled up into a re-useable entity (and it gets a nice configuration UI to boot!).  This concept is a little different than traditional workflow design, in that you dont have to think of an end-to-end process around passing a case along a path, rather, you must envision the case as central object with workflow threads branching off of it and doing their own thing with the case data.  Certainly there can be certain workflow threads that get rather complex, but the idea is that they RELATE to the case, they dont BECOME the case (though it is still possible with action->status mappings to prevent certain actions in certain cases, so it isnt always a wide-open free for all of actions on a case). I realize that this description of the Case Management Framework merely scratches the surface on what the product actually can do, and I dont think Ive conclusively defined for what sort of business scenario you can make a case for Case Management Framework.  What I do hope to have accomplished with this post is to raise awareness of CMF there is a (free!) product out there that could potentially simplify a tangled workflow process and give (for free!) a very useful set of SharePoint web parts and a nice set of (free!) reports.  The best way to see if it will truly fit your needs is to give it a try did I mention it is FREE?  Er, ok, so it is free, but only obtainable at this time for K2 partnersDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • R12.0 Cash Management Consolidated Patch Collection (CPC) And R12.1 Cash Management Recommended Patch Collection (RPC)

    - by user793553
    If you have Oracle E-Business Suite's Cash Management (CE) application installed, you'll want to be sure to install the latest CPC (Consolidated Patch Collection) if you are using a R12.0 version of the apps, or the latest RPC (Recommended Patch Collection) for the R12.1 version of the apps. These collections give you all the fixes currently available for known issues in the specified versions of the application, including all of the latest Root Cause Analysis Fixes (RCAs)! What is an "RPC" (for R12.1 users)? Since the release of 12.1, a number of recommended patches for Oracle Cash Management have been made available as standalone patches to help address important business process issues. Adoption of these patches was highly recommended at the time, but not always implemented, so to further facilitate adoption of these patches, Oracle consolidated them into product-specific Recommended Patch Collections (RPCs) - a collection of recommended patches. They were created by Oracle Development with the following goals in mind: Stability: To address data integrity issues that have been identified by Oracle Development and Oracle Software Support as having the potential to interfere with the normal completion of important business processes (such as, period close, etc.). Root Cause Fixes (RCAs): To make available root cause fixes for known data integrity issues. Compact: To keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: To compile the collection of patches based on functional areas, allowing a customer to apply multiple RPCs at once, or in phases (based on individual needs and goals). Where to start ALL R12 Cash Management users (R12.0 and R12.1 users) should start with the following Note on My Oracle Support (MOS): Doc ID 1367845.1: R12: Cash Management Recommended Patch Collections It's a great place for important implementation information about both sets of critical patch collections! For R12.1x users R12.1 users should also take a look at the documents below for even more information about the RPC for the R12.1.x versions of the Cash Management application, and other related available RPCs: Note Number  Title                                                                                                      1489997.1 Master Troubleshooting Guide for CE: Reconciliation & Clearing [VIDEO] 954704.1 EBS: R12.1 Oracle Financials Recommended Patch Collections (RPCs) 1316506.1 R12: Oracle CE: Upgrading from R11i to R12.1: Latest Recommended Patches Patch Wizard Utility While a patch may contain several hundred files, the impact on your system may actually be minimal. Patches contain hard prerequisites that are intended to make a patch work on a very low code baseline. The Patch Wizard Utility will give you a detailed analysis of the patch’s impact on your instance BEFORE it’s applied, so you’ll know exactly what to expect from the application. Please refer to Doc ID 976188.1 for more information on this important utility

  • LexisNexis and Oracle Join Forces to Prevent Fraud and Identity Abuse

    - by Tanu Sood
    Author: Mark Karlstrand About the Writer:Mark Karlstrand is a Senior Product Manager at Oracle focused on innovative security for enterprise web and mobile applications. Over the last sixteen years Mark has served as director in a number of tech startups before joining Oracle in 2007. Working with a team of talented architects and engineers Mark developed Oracle Adaptive Access Manager, a best of breed access security solution.The world’s top enterprise software company and the world leader in data driven solutions have teamed up to provide a new integrated security solution to prevent fraud and misuse of identities. LexisNexis Risk Solutions, a Gold level member of Oracle PartnerNetwork (OPN), today announced it has achieved Oracle Validated Integration of its Instant Authenticate product with Oracle Identity Management.Oracle provides the most complete Identity and Access Management platform. The only identity management provider to offer advanced capabilities including device fingerprinting, location intelligence, real-time risk analysis, context-aware authentication and authorization makes the Oracle offering unique in the industry. LexisNexis Risk Solutions provides the industry leading Instant Authenticate dynamic knowledge based authentication (KBA) service which offers customers a secure and cost effective means to authenticate new user or prove authentication for password resets, lockouts and such scenarios. Oracle and LexisNexis now offer an integrated solution that combines the power of the most advanced identity management platform and superior data driven user authentication to stop identity fraud in its tracks and, in turn, offer significant operational cost savings. The solution offers the ability to challenge users with dynamic knowledge based authentication based on the risk of an access request or transaction thereby offering an additional level to other authentication methods such as static challenge questions or one-time password when needed. For example, with Oracle Identity Management self-service, the forgotten password reset workflow utilizes advanced capabilities including device fingerprinting, location intelligence, risk analysis and one-time password (OTP) via short message service (SMS) to secure this sensitive flow. Even when a user has lost or misplaced his/her mobile phone and, therefore, cannot receive the SMS, the new integrated solution eliminates the need to contact the help desk. The Oracle Identity Management platform dynamically switches to use the LexisNexis Instant Authenticate service for authentication if the user is not able to authenticate via OTP. The advanced Oracle and LexisNexis integrated solution, thus, both improves user experience and saves money by avoiding unnecessary help desk calls. Oracle Identity and Access Management secures applications, Juniper SSL VPN and other web resources with a thoroughly modern layered and context-aware platform. Users don't gain access just because they happen to have a valid username and password. An enterprise utilizing the Oracle solution has the ability to predicate access based on the specific context of the current situation. The device, location, temporal data, and any number of other attributes are evaluated in real-time to determine the specific risk at that moment. If the risk is elevated a user can be challenged for additional authentication, refused access or allowed access with limited privileges. The LexisNexis Instant Authenticate dynamic KBA service plugs into the Oracle platform to provide an additional layer of security by validating a user's identity in high risk access or transactions. The large and varied pool of data the LexisNexis solution utilizes to quiz a user makes this challenge mechanism even more robust. This strong combination of Oracle and LexisNexis user authentication capabilities greatly mitigates the risk of exposing sensitive applications and services on the Internet which helps an enterprise grow their business with confidence.Resources:Press release: LexisNexis® Achieves Oracle Validated Integration with Oracle Identity Management Oracle Access Management (HTML)Oracle Adaptive Access Manager (pdf)

  • Javascript new keyword and memory management

    - by Whyamistilltyping
    Coming from C++ it is hard grained into my mind that everytime I call new I call delete. In javascript I find myself calling new occasionally in my code but (hoping) the garbage collection functionality in the browser will take care of the mess for me. I don't like this - is there a 'delete' method in javascript and is how I use it different from in C++? Thanks.

  • User management for google apps

    - by Ali
    Hi guys, I'm modifying our collaboration system so it can be listed on google applications. A small issue I'm facing is the registering of user details. By default whenever someone logs into their google Apps account they pretty much are logged into the application. For every action taken by a registered login in user I store the user ID of that signed in user whenever an update is made in the database. However the google apps user sign in process is different in this respect that there isn't anything visible as a user ID for me to work with. Any ideas?

  • SQL Server Management Studio Express 2005 has no Configuration Manager

    - by brohjoe
    Where is the configuration manager for SQL Express 2005? I need to configure SQL Server for TCP/IP but there is no configuration manager with the package. I see SQL Server Database Publishing Wizard, I see SQL Server Migration Assistant for Access, but no Configuration Manager. According to the MSDN, there should be one. I've even looked online for a download of the Configuration Manager for SQL Server 2005, but could not find one. Did I miss something in the download or should I just scrap SQL Server Express and download the full-blown SQL Server for Developers?

  • Memory management in objective-c

    - by prathumca
    I have this code in one of my classes: - (void) processArray { NSMutableArray* array = [self getArray]; . . . [array release]; array = nil; } - (NSMutableArray*) getArray { //NO 1: NSMutableArray* array = [[NSMutableArray alloc]init]; //NO 2: NSMutableArray* array = [NSMutableArray array]; . . . return array; } NO 1: I create an array and return it. In the processArray method I release it. NO 2: I get an array by simply calling array. As I'm not owner of this, I don't need to release it in the processArray method. Which is the best alternative, NO 1 or NO 2? Or is there a better solution for this?

  • Objective-C (iPhone) Memory Management

    - by Steven
    I'm sorry to ask such a simple question, but it's a specific question I've not been able to find an answer for. I'm not a native objective-c programmer, so I apologise if I use any C# terms! If I define an object in test.h @interface test : something { NSString *_testString; } Then initialise it in test.m -(id)init { _testString = [[NSString alloc] initWithString:@"hello"]; } Then I understand that I would release it in dealloc, as every init should have a release -(void)dealloc { [_testString release]; } However, what I need clarification on is what happens if in init, I use one of the shortcut methods for object creation, do I still release it in dealloc? Doesn't this break the "one release for one init" rule? e.g. -(id)init { _testString = [NSString stringWithString:@"hello"]; } Thanks for your helps, and if this has been answered somewhere else, I apologise!!

  • Cocoa memory management

    - by silvio
    At various points during my application's workflow, I need so show a view. That view is quite memory intensive, so I want it to be deallocated when it gets discarded by the user. So, I wrote the following code: - (MyView *)myView { if (myView != nil) return myView; myView = [[UIView alloc] initWithFrame:CGRectZero]; // allocate memory if necessary. // further init here return myView; } - (void)discardView { [myView discard]; // the discard methods puts the view offscreen. [myView release]; // free memory! } - (void)showView { view = [self myView]; // more code that puts the view onscreen. } Unfortunately, this methods only works the first time. Subsequent requests to put the view onscreen result in "message sent to deallocated instance" errors. Apparently, a deallocated instance isn't the same thing as nil. I thought about putting an additional line after [myView release] that reads myView = nil. However, that could result in errors (any calls to myView after that line would probably yield errors). So, how can I solve this problem?

  • stack and heap issue for iPhone memory management

    - by Forrest
    From this post I got know that the Objective-C runtime does not allow objects to be instantiated on the stack, but only on the heap; this means that you don’t have “automatic objects”, nor things like auto_ptr objects to help you manage memory; Someone give one example in post Objective C: Memory Allocation on stack vs. heap NSString* str = @"hello"; but this NSString is also not allocated in stack. Feel odd that this str is static. (Who can explain this ? ) Question here is that why there is no heap ? even mixing c++ together with Object C ? /////////////////////////////// Clear my question /////////////////////////////// I am confused , so questions are not clear. Let me put in this way. 1) All Object C objects should be alloc in stack ? ( I think yes ) 2)In C++, there are stack for memory, so for iOS app, also have stack ? ( I think yes ) 3) for iOS app, if only use Object C, so what is the usage of stack ? what kind of objects should use stack then ?

  • Best Practices for Setup and Management of an Open Source Project

    - by VirtuosiMedia
    Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

  • java memory management

    i have the following code snapshot: public void getResults( String expression, String collection ){ ReferenceList list; Vector lists = new Vector(); list = invertedIndex.get( 1 )//invertedIndex is class member lists.add(list); } when the method is finished, i supose that the local objects ( list, lists) are "destroyed". Can you tell if the memory occupied by list stored in invertedIndex is released as well? Or does java allocate new memory for list when assigning list = invertedIndex.get( 1 );

  • Sql Server Compact - Schema Management

    - by Richard B
    I've been searching for some time for a good solution to implement the idea of managing schema on a Sql Server Compact 3.5 db. I know of several ways of managing schema on Sql Express/std/enterprise, but Compact Edition doesn't support the necessary tools required to use the same methodology. Any suggestions/tips? I should expand this to say that it is for 100+ clients with wrapperware software. As the system changes, I need to publish update scripts alongside the new binaries to the client. I was looking for a decent method by which to publish this without having to just hand the client a script file and say "Run this in SSMSE". Most clients are not capable of doing such a beast. A buddy of mine disclosed a partial script on how to handle the SQL Server piece of my task, but never worked on Compact Edition... It looks like I'll be on my own for this. What I think that I've decided to do, and it's going to need a "geek week" to accomplish, is that I'm going to write some sort of tool much like how WiX and nAnt works, so that I can just write an overzealous Xml document to handle the work. If I think that it is worthwhile, I'll publish it on CodePlex and/or CodeProject because I've used both sites a bit to gain better understanding of concepts for jobs I've done in the past, and I think it is probably worthwhile to give back a little.

  • UINavigationController and memory management

    - by Dan Ray
    - (void)launchSearch { EventsSearchViewController *searchController = [[EventsSearchViewController alloc] initWithNibName:@"EventsSearchView" bundle:nil]; [self.navigationController pushViewController:searchController animated:YES]; //[searchController release]; } Notice the [searchController release] is commented out. I've understood that pushing searchController onto the navigation controller retains it, and I should release it from my code. I did just alloc/init it, after all, and if I don't free it, it'll leak. With that line commented out, navigation works great. With it NOT commented out, I can navigate INTO this view okay, but coming back UP a level crashes with a *** -[CFArray release]: message sent to deallocated instance 0x443a9e0 error. What's happening here? Is the NavigationController releasing it for me somehow when it goes out of view? The boilerplate that comes on a UINavigationController template in XCode has the newly-pushed controller getting released. But when I do it, it fails.

    I have already created the program to restart a SQL database but it only works if the client has the rights. This is going to be done on a local network from a client computer when they can't get a person that has the password on the phone. Any thoughts I'm currently using the servicecontroller to start and stop database. When I don't have the rights I get a access denied error, or This operation might require other privileges. Not sure if impersonation would work since I don't have the userid and password.
