  • Best practice for remote topic subscription with HA

    I'd like to create an orchestrator EJB, in cluster A, that must persist some data to a database of record and then publish a business event to a topic. I have two durable subscribers, MDBs on clusters B & C, that need to receive the events and perform some persistence on their side.
              I'd like HA so that a failure in any managed server would not interrupt the system. I can live with at least once delivery, but at the same time I'd like to minimize the amount of redundant message processing.
              The documentation gets a little convoluted when dealing with clustering. What is the best practice for accomplishing this task? Has anyone successfully implemented a similar solution?
              I'm using Weblogic 8.1 SP5, but I wouldn't mind hearing solutions for later versions as well.

    A managed server failure makes that server's JMS servers unavailable, which, in turn, makes the JMS server's messages unavailable until the either (A) the JMS server is migrated or (B) the managed server is restarted.
              For more discussion, see my post today on topic "distributed destinations failover - can't access messages from other node". Also, you might be interested in the circa 8.1 migration white-paper on dev2dev: http://dev2dev.bea.com/pub/a/2004/05/ClusteredJMS.html

  • Best practices for setting up users on a small office network?

    Hello,
    I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
    Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
    Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
    All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
    Thank you,

    Hi,
    Thanks for your posting.
    When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.
    For more and detail information, please refer to:

  • Best-practice for Catalog Views ? :|

    Hello community,
    A best practice question:
    The situtation: I have several product categories (110), several items in those categories (4000) and 300 end-users.    I would like to know which is the best practice for segment the catalog.   I mean, some users should only see categories 10,20 & 30.  Other users only category 80, etc.    The problem is how can I implement this ?
    My first idea is:
    1. Create 110 Procurement Catalogs (1 for every prod.category).   Each catalog should contain only its product category.
    2. Assign in my Org Model, in a user-level all the "catalogs" that the user should access.
    Do you have any idea in order to improve this ?
    Saludos desde Mexico,

    Hi,
    Your way of doing will work, but you'll get maintenance issues (to many catalogs, and catalog link to maintain for each user).
    The other way is to built your views in CCM, and assign these views to the users, either on the roles (PFCG) or on the user (SU01). The problem is that with CCM 1.0 this is limitated, cause you'll have to assign one by one the items to each view (no dynamic or mass processes), it has been enhanced in CCM 2.0.
    My advice:
    -Challenge your customer about views, and try to limit the number of views, with for example strategic and non strategic
    -With CCM 1.0 stick to the procurement catalogs, or implement BADIs to assign items to the views (I experienced it, it works, but is quite difficult), but with a limitated number of views
    Good luck.

  • Best Practice for Securing Web Services in the BPEL Workflow

    What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
    They are all deployed on the same oracle application server.
    Defining agent for each?
    Gateway for all?
    BPEL security extension?
    The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
    Regards
    Farbod

    It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
    The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
    Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
    If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
    Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
    You can enforce rules at your network layer to allow access to the App server only from Gateway.
    When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
    The next BPEL developer in your project may not be aware of Security extensions
    Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.

  • Best practice for multi-language content in common areas

    I've got a site with some text in header/footer/nav that needs to be translated between an English and Spanish site, which use the same design. My intention was to set up all the text as content to facilitate. However, if I use a standard dialog with the component's path set to a child of the current page node, I would need to re-enter the text on every page. If I use a design dialog, or a standard dialog with the component's path set absolutely, the Engilsh and Spanish sites will share the same text. If I use a standard dialog with the component's path set relatively (eg path="../../jcr:content/myPath"), the pages using the component would all need to be at the same level of the hierarchy.
    It appears that the Geometrixx demo doesn't address this situation, and leaves copy in English. Is there a best practice for this scenario?

    I'm finding that something to the effect of <cq:include path="<%= strCommonContentPath + "codeEntry" %>" resourceType ...
    works fine for most components, but not for parsys, or a component containing a parsys. When I attempt that, I get a JS error that says "design.path is null or not an object". Is there a way around this?

  • Best practices for ARM - please help!!!

    Hi all,
    Can you please help with any pointers / links to documents describing best practices for "who should be creating" the GRC request in below workflow of ARM in GRC 10.0??
    Create GRC request -> role approver -> risk manager -> security team
    options are : end user / Manager / Functional super users / security team.
    End user and manager not possible- we can not train so many people. Functional team is refusing since its a lot of work. Please help me with pointers to any best practices documents.
    Thanks!!!!

    In this case, I recommend proposing that the department managers create GRC Access Requests.  In order for the managers to comprehend the new process, you should create a separate "Role Catalog" that describes what abilities each role enables.  This Role Catalog needs to be taught to the department Managers, and they need to fully understand what tcodes and abilities are inside of each role.  From your workflow design, it looks like Role Owners should be brought into these workshops.
    You might consider a Role Catalog that the manager could filter on and make selections from.  For example, an AP manager could select "Accounts Payable" roles, and then choose from a smaller list of AP-related roles.  You could map business functions or tasks to specific technical roles.  The design flaw here, of course, is the way your technical roles have been designed.
    The point being, GRC AC 10 is not business-user friendly, so using an intuitive "Role Catalog" really helps the managers understand which technical roles they should be selecting in GRC ARs.  They can use this catalog to spit out a list of technical role names that they can then search for within the GRC Access Request.
    At all costs, avoid having end-users create ARs.  They usually select the wrong access, and the process then becomes very long and drawn out because the role owners or security stages need to mix and match the access after the fact.  You should choose a Requestor who has the highest chance of requesting the correct access.  This is usually the user's Manager, but you need to propose this solution in a way that won't scare off the manager - at the end of the day, they do NOT want to take on more work.
    If you are using SAP HR, then you can attempt HR Triggers for New User Access Requests, which automatically fill out and submit the GRC AR upon a specific HR action (New Hire, or Termination).  I do not recommend going down this path, however.  It is very confusing, time consuming, and difficult to integrate properly.
    Good luck!

  • Best Practices For Household IOS's/Apple IDs

    Greetings:
    I've been searching support for best practices for sharing primarily apps, music and video among multple iOS's/Apple IDs.  If there is a specific article please point me to it.
    Here is my situation: 
    We currently have 3 iPads (2-kids, 1-dad) in the household and one iTunes account on a win computer.  I previously had all iPads on single Apple ID/credit card and controlled the kids' downloads thru the Apple ID password that I kept secret.  As the kids have grown older, I found myself constantly entering my password as the kids increased there interest in music/apps/video.  I like this approach because all content was shared...I dislike because I was constantly asked to input password for all downloads.
    So, I recently set up an individual account for them with the allowance feature at iTunes that allows them to download content on their own (I set restrictions on their iPads).  Now I have 3 Apple IDs under one household.
    My questions:
    With the 3 Apple IDs, what is the best way to share apps,music, videos among myself and the kids?  Is it multiple accounts on the computer and some sort of sharing? 
    Thanks in advance...

    Hi Bonesaw1962,
    We've had our staff and students run iOS updates OTA via Settings -> Software Update. In the past, we put a DNS block on Apple's update servers to prevent users from updating iOS (like last fall when iOS 7 was first released). By blocking mesu.apple com, the iPads weren't able to check for or install any iOS software updates. We waited until iOS 7.0.3 was released before we removed the block to mesu.apple.com at which point we told users if they wanted to update to iOS 7 they could do so OTA. We used our MDM to run reports periodically to see how many people updated to iOS 7 and how many stayed on iOS 6. As time went on, just about everyone updated on their own.
    If you go this route (depending on the number of devices you have), you may want to take a look at Caching Server 2 to help with the network load https://www.apple.com/osx/server/features/#caching-server . From Apple's website, "When a user on your network downloads new software from Apple, a copy is automatically stored on your server. So the next time other users on your network update or download that same software, they actually access it from inside the network."
    I wish there was a way for MDMs to manage iOS updates, but unfortunately Apple hasn't made this feature available to MDM providers. I've given this feedback to our Apple SE, but haven't heard if it is being considered or not. Keeping fingers crossed.
    Hope this helps. Let us know what you decide on and keep us posted on the progress. Good luck!!

  • Basic Strategy / Best Practices for System Monitoring with Solution Manager

    I am very new to SAP and the Basis group at my company. I will be working on a project to identify the best practices of System and Service level monitoring using Solution Manager. I have read a good amount about SAP Solution Manager and the concept of monitoring but need to begin mapping out a monitoring strategy.
    We currently utilize the RZ20 transaction and basic CCMS monitors such as watching for update errors, availability, short dumps, etc.. What else should be monitored in order to proactively find possible issues. Are there any best practices you all have found when implimenting Monitoring for new solutions added to the SAP landscape.... what are common things we would want to monitor over say ERP, CRM, SRM, etc?
    Thanks in advance for any comments or suggestions!

    Did you try the following link ?
    If not, it may be useful to some extent:

    ---> Cross-Industry Packages ---> Best Practices for Solution Management
    You have quite a few documents there - those on BPM may also cover Solution Monitoring aspects.

  • Best practice for integrating a 3 point metro-e in to our network.

    Hello,
    We have just started to integrate a new 3 point metro-e wan connection to our main school office. We are moving from point to point T-1?s to 10 MB metro-e. At the main office we have a 50 MB going out to 3 other sites at 10 MB each. For two of the remote sites we have purchase new routers ? which should be straight up configurations. We are having an issue connecting the main office with the 3rd site.
    At the main office we have a Catalyst 4006 and at the 3rd site we are trying to connect to a catalyst 4503.
    I have attached configurations from both the main office and 3rd remote site as well as a basic diagram of how everything physically connects. These configurations are not working ? we feel that it is a gateway type problem ? but have reached no great solutions. We have tried posting to a different forum ? but so far unable to find the a solution that helps.
    The problem I am having is on the remote side. I can reach the remote catalyst from the main site, but I cannot reach the devices on the other side of the remote catalyst however the remote catalyst can see devices on it's side as well as devices at the main site.
    We have also tried trunking the ports on both sides and using encapsulation dot10q ? but when we do this the 3rd site is able to pick up a DHCP address from the main office ? and we do not feel that is correct. But it works ? is this not causing a large broad cast domain?
    If you have any questions or need further configuration data please let me know.
    The previous connection was a T1 connection through a 2620 but this is not compatible with metro-e so we are trying to connect directly through the catalysts.
    The other two connection points will be connecting through cisco routers that are compatible with metro-e so i don't think I'll have problems with those sites.
    Any and all help is greatly welcome ? as this is our 1st metro e project and want to make sure we are following best practices for this type of integration.
    Thank you in advance for your help.
    Jeff

    Jeff, form your config it seems you main site and remote site are not adjacent in eigrp.
    Try adding a network statement for the 171.0 link and form a neighbourship between main and remote site for the L3 routing to work.
    Upon this you should be able to reach the remote site hosts.

  • BEST PRACTICES FOR CREATING DISCOVERER DATABASE CONNECTION -PUBLIC VS. PRIV

    I have enabled SSO for Discoverer. So when you browse to http://host:port/discoverer/viewer you get prompted for your SSO
    username/password. I have enabled users to create their own private
    connections. I log in as portal and created a private connection. I then from
    Oracle Portal create a portlet and add a discoverer worksheet using the private
    connection that I created as the portal user. This works fine...users access
    the portal they can see the worksheet. When they click the analyze link, the
    users are prompted to enter a password for the private connection. The
    following message is displayed:
    The item you are requesting requires you to enter a password. This could occur because this is a private connection or
    because the public connection password was invalid. Please enter the correct
    password now to continue.
    I originally created a public connection...and then follow the same steps from Oracle portal to create the portlet and display the
    worksheet. Worksheet is displayed properly from Portal, when users click the
    analyze link they are taken to Discoverer Viewer without having to enter a
    password. The problem with this is that when a user browses to
    http://host:port/discoverer/viewer they enter their SSO information and then
    any user with an SSO account can see the public connection...very insecure!
    When private connections are used, no connection information is displayed to
    SSO users when logging into Discoverer Viewer.
    For the very first step, when editing the Worksheet portlet from Portal, I enter the following for Database
    Connections:
    Publisher: I choose either the private or public connection that I created
    Users Logged In: Display same data to all users using connection (Publisher's Connection)
    Users Not Logged In: Do no display data
    My question is what are the best practices for creating Discoverer Database
    Connections.
    Is there a way to create a public connection, but not display it in at http://host:port/discoverer/viewer?
    Can I restrict access to http://host:port/discoverer/viewer to specific SSO users?
    So overall, I want roughly 40 users to have access to my Portal Page Group. I then want to
    display portlets with Discoverer worksheets. Certain worksheets I want to have
    the ability to display the analyze link. When the SSO user clicks on this they
    will be taken to Discoverer Viewer and prompted for no logon information. All
    SSO users will see the same data...there is no need to restrict access based on
    SSO username...1 database user will be set up in either the public or private
    connection.

    You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
    So that it won't ask for password.
    Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information

  • Best Practices for Using Photoshop (and Computing in General)

    I've been seeing some threads that lead me to realize that not everyone knows the best practices for doing Photoshop on a computer, and in doing conscientious computing in general.  I thought it might be a good idea for those of us with some exprience to contribute and discuss best practices for making the Photoshop and computing experience more reliable and enjoyable.
    It'd be great if everyone would contribute their ideas, and especially their personal experience.
    Here are some of my thoughts on data integrity (this shouldn't be the only subject of this thread):
    Consider paying more for good hardware. Computers have almost become commodities, and price shopping abounds, but there are some areas where spending a few dollars more can be beneficial.  For example, the difference in price between a top-of-the-line high performance enterprise class hard drive and the cheapest model around with, say, a 1 TB capacity is less than a hundred bucks!  Disk drives do fail!  They're not all created equal.  What would it cost you in aggravation and time to lose your data?  Imagine it happening at the worst possible time, because that's exactly when failures occur.
    Use an Uninterruptable Power Supply (UPS).  Unexpected power outages are TERRIBLE for both computer software and hardware.  Lost files and burned out hardware are a possibility.  A UPS that will power the computer and monitor can be found at the local high tech store and doesn't cost much.  The modern ones will even communicate with the computer via USB to perform an orderly shutdown if the power failure goes on too long for the batteries to keep going.  Again, how much is it worth to you to have a computer outage and loss of data?
    Work locally, copy files elsewhere.  Photoshop likes to be run on files on the local hard drive(s).  If you are working in an environment where you have networking, rather than opening a file right off the network, then saving it back there, consider copying the file to your local hard drive then working on it there.  This way an unexpected network outage or error won't cause you to lose work.
    Never save over your original files.  You may have a library of original images you have captured with your camera or created.  Sometimes these are in formats that can be re-saved.  If you're going to work on one of those files (e.g., to prepare it for some use, such as printing), and it's a file type that can be overwritten (e.g., JPEG), as soon as you open the file save the document in another location, e.g., in Photoshop .psd format.
    Save your master files in several places.  While you are working in Photoshop, especially if you've done a lot of work on one document, remember to save your work regularly, and you may want to save it in several different places (or copy the file after you have saved it to a backup folder, or save it in a version management system).  Things can go wrong and it's nice to be able to go back to a prior saved version without losing too much work.
    Make Backups.  Back up your computer files, including your Photoshop work, ideally to external media.  Windows now ships with a quite good backup system, and external USB drives with surprisingly high capacity (e.g., Western Digital MyBook) are very inexpensive.  The external drives aren't that fast, but a backup you've set up to run late at night can finish by morning, and if/when you have a failure or loss of data.  And if you're really concerned with backup integrity, you can unplug an external drive and take it to another location.
    This stuff is kind of "motherhood and apple pie" but it's worth getting the word out I think.
    Your ideas?
    -Noel

    APC Back-UPS XS 1300.  $169.99 at Best Buy.
    Our power outages here are usually only a few seconds; this should give my server about 20 or 25 minutes run-time.
    I'm setting up the PowerChute software now to shut down the computer when 5 minutes of power is left.  The load with the monitor sleeping is 171 watts.
    This has surge protection and other nice features as well.

  • Best Practices for Defining NDS Java Projects...

    We are doing a Proof of Concept on using NDS to develop non-SAP Java applications.  We are attempting to determine if we can replace our current Java development tools with NDS/WAS.
    We are struggling with SAP's terminology and "plumbing" for setting up/defining Java projects.  For example, what is and when do you define Tracks, Software Components, Development Components, etc.  All of these terms are totally foreign to us and do not relate to our current Java environment (at least not that we can see).  We are also struggling with how the DTR and activities tie in to those components.
    If any one has defined best practices for setting up Java projects or has struggled with and overcome these same issues, please provide us with some guidance.  This is a very frustrating and time-consuming issue for us.
    Thank you!!

    Hi Peggy,
    In Component Model we divide software projects into small components.Components can use other components in well defined manner.
    A development object is a part of a component that can be changed or developed in some way; it provides the component with a certain part of its functionality. A development object may be a Java class, a Web Dynpro view, a table definition, a JSP page, and so on. Development objects are always stored as “sources” in a repository.
    A development component can be defined as a frame shared by a number of objects, which are part of the software.
    Software components combine components (DCs) to larger units for delivery and deployment.
    A track comprises configurations and runtime systems required for developing software component versions.It ensures stable states of deliverables used by subsequent tracks.
    The Design Time Repository is for versioning source code management. Distributed development of software in teams. Transport and replication of sources.
    You can also find lot of support in SDN for the above concepts with tutorials.
