What is best practice for deploying agent(10204) on RAC 9i

Hello,
What would be best practice for deploying agent(10204) on RAC 9i? Should the agent be deployed on each node or should the agent be deployed on the cluster file system? What are the advantages/disavantages deploy on individual nodes vs. on cluster file system? Please advice. Thank you in advance.

Please use agent push application to deploy agent on all the nodes at one shot

    What is best practice for deploying applications through the IPCU to 10 ipads?
    I'm looking for a complete step-by-step of the best way to do this.
    Thanks in advance!

    Just place a modem into any console port. Ideally you use a terminal server, but is not always really needed.

  • What are best practice for packaging and deploying j2EE apps to iAS?

    We've been running a set of J2EE applications on a pair of iAS SP1b for about a year and it has been quite stable.
    Recently however we have had a number of LDAP issues, particularly when registering and unregistering applications (registering ear files sometimes fails 1st time but may work 2nd time). Also We've noticed very occasionally that old versions of classes sometimes find their way onto our machines.
    What is considered to be best practice in terms of packaging and deployment, specifically:
    1) Packaging - using the deployTool that comes with iAS6 SP1b to package is a big manual task, especially when you have 200+ jsp files. Are people out there using this or are they scripting it with a build tool such as Ant?
    2) Deploying an existing application to multiple iAS's. Are you guys unregistering old application then reregistering new application? Are you shutting down iAS whilst doing the deployment?
    3) Deploying ear files can take 5 to 10 mins, is this normal?
    4) In a clustered scenario where HTTPSession is shared what are the consequences of doing deployments to data stored in session?
    thanks in asvance for your replies

    You may want to consider upgrading your application server environment to a newer service pack. There are numerous enhancements involving the deployment tool and run time layout of your application that make clear where you're application is loading its files from.
    If you've at a long running application server environment, with lots of deployments under your belt, you might start to notice slow downs in deployment and kjs start time. Generally this is due to garbage collecting in your iAS registry.
    You can do several things to resolve this. The most complete solution is to reinstall the application server. This will guarantee a clean ldap registry. Of course you've got to restablish your configurations and redeploy your applications. When done, backup your application server install space with the application server and directory server off. You can use this backup to return to a known configuation at some future time.
    For the second method: <B>BE CAREFUL - BACKUP FIRST</B>
    There is a more exhaustive solution that involves examining your deployed components to determine the active GUIDS. You then search the NameTrans section of the registry searching for Applogic Servlet *, and Bean * entries that represent your previously deployed components but are represented in the set of deployed GUIDs. Record these older GUIDs, remove them from ClassImp and ClassDef. Finally remove the older entries from NameTrans.
    Best practices for deployment depend on your particular environmental needs. Many people utilize ANT as a build tool. In later versions of the application server, complete ANT scripts are included that address compiling, assembly and deployment. Ant 1.4 includes iAS specific targets and general J2EE targets. There are iAS specific targets that can be utilized with the 1.3 version. Specialized build targets are not required however to deploy to iAS.
    Newer versions of the deployment tool allow you to specify that JSPs are not to be registered automatically. This can be significant if deployment times lag. Registered JSP's however benefit more fully from the services that iAS offers.
    2) In general it is better to undeploy then redeploy. However, if you know that you're not changing GUIDs, recreating an existing application with new GUIDs, or removing registered components, you may avoid the undeploy phase.
    If you shut down the KJS processes during deployment you can eliminate some addition workload on the LDAP server which really gets pounded during deployment. This is because the KJS processes detect changes and do registry loads to repopulate their caches. This can happen many times during a deployment and does not provide any benefit.
    3) Deploying can be a lengthy process. There have been improvements in that performance from service pack to service pack but unfortunately you wont see dramatic drops in deployment times.
    One thing you can do to reduce deployment times is to understand the type of deployment. If you have not manipulated your deployment descriptors in any way, then there is no need to deploy. Simply drop your newer bits in to the run time space of the application server. In later service packs this means exploding the package (ear,war, or jar) in to the appropriate subdirectory of the APPS directory.
    4) If you've changed the classes of objects that have been placed in HTTPSession, you may find that you can no longer utilize those objects. For that reason, it is suggested that objects placed in session be kept as simple as possible in order to minimize this effect. In general however, is not a good idea to change a web application during the life span of a session.

  • Best Practice for Deploying ADF application

    I am tasked with developing a best or prefered practice of feploying a large ADF application. Background: we are in the process of redeveloping a UI for a large system. We have broken the system down into susbsytems. Each of these susbsystems UI will be a ADF aaplicaion(?). This is a move from a MS .Net front end. The backend (Batch processes etc) is being dveloped in Java. So my question is if I have several ADF projects for each subsystem and common components that they all will use - what is the best practice to compile package and deploy? The deployment will be to weblogic server or servers(Cluster).
    We have a team of at least 40 -50 developers worldwide so we are looking for an automated build and deploy and would like to follow Oracle best practice. So far I have read Deploying ADF Applications (http://download.oracle.com/docs/cd/E15523_01/web.1111/e15470/deploy.htm#BGBJHGFH) and have followed the links. I have also look at the ADF evangalist blogs - lots of chatter about ojdeploy. My concern about ojdeploy is that dependent files are also being compiled at the same time. I expected that we want shared dependent files compiled only once (Is that a valid concern)?
    So then when we build the source out of subversion (ojdeploy ? Ant? ) then what is best practice to deploy to a weblogic server (wslt admin console) - again we want it to be automated.
    Thank you in advance for replies.
    RK

    Rule 1: Never use the "Automatically Expose UI Componentes in a New Managed Bean" option, create your bindings manually;
    Rule 2: Rule 1 is always right;
    Rule 3: In doubts, refer to rule 2.

I am thinking just to consolidate all these schema's in one db.Unless you are really starved for resources, I would not recommend storing the OID and OEM repositories in the same database. Both of these repositories support different products, and you risk creating unnecessary dependencies when patching or upgrading. As a completely fictitious example, what if your OID installation has a critical issue that requires a repository database upgrade to version 10.2.0.6, and the Grid Control repository database is only certified for version 10.2.0.5?

  • What's best practice for logging messages in pageflow?

    What's best practice for logging messages in pageflow?
    Workshop complains when I try to use a Log4J logger by saying it's not serializable. Is there a context similar to JWSContext that you can get a logger from?
    There seems to be a big hole in the documentation on debug logging in workflows and JSP pages.
    thanks,
    Rodger...

    Make the configuration change in setDomainEnv.cmd. Find where the following variable is set:
    LOG4J_CONFIG_FILE
    and change it to your desired path.
    In your Global.app class, instantiate a static Logger like this:
    transient static Logger logger = Logger.getLogger(Global.class);
    You should be logging now as long as you have the categories and appenders configured properly in your log4j.xml file.

  • What is best practice for installing Yosemite

    I am currently on OS X Mavericks version 10.9.5 Macbook pro 13.  2.6 ghz intel for i5, 8gb 1600 mhz ddr3.
    I am now downloading yosemite 10.10.1 but since i've been reading all these negative feedback so far, i am having second thoughts if i should continue to install the upgrade or not.
    Any suggestion What is best practice for installing Yosemite?  Or is it not yet time to upgrade since the platform is premature yet?
    Thanks in advance.

    Check your apps are compatible with 10.10 - roaringapps.com
    http://www.etresoft.com/etrecheck can show what is running & installed - look for updates on the developer own sites.
    If you have many kernel extensions or startup items look for updates to them too
    Take a full bootable backup to another disk via Carbon Copy Cloner, Super Duper! or Disk Utility
    Disconnect the backup before you begin any install (ideally set it aside & leave it untouched incase you need to go back to 10.9)
    Personally I prefer a clean install when there are signs of multiple migrations (if you have upgraded several OS for a period of years). Setup Assistant/ Migration Assistant can import user data from a backup, but consider that Apps & 'other data' should be manually reinstalled from the latest versions.
    If you clean install (erase the HD before installation) then make sure you deauthorise iTunes & any other apps that are associated online (like find my Mac).

  • What are best practices for managing my iphone from both work and home computers?

    What are best practices for managing my iphone from both work and home computers?

    Sync iPod/iPad/iPhone with two computers
    Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
    I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans withiTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
    As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
    When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entires and import the local content you have on that box.

  • Best practices for updating agents

    We're getting ready to do our first system-wide update of agents to fix a critical bug. Our summer vacation is just ending, and teachers and students will be coming back very soon and turning on our Windows 7 computers for the first time in many weeks, although they won't all be turned on the same day. When they are turned on they will be attempting to get various updates, in particular Windows updates, but also Flash Player and Adobe Reader. I need to update the agents as quickly as possible, but I'm concerned about the possibility of the agent update conflicting with another update, especially Windows updates. Isn't it possible that Windows Update could restart a computer while the agent update is happening (or the other way around), leaving the machine in an unstable or unusable state? What are the best practices for dealing with this? I considered the possibility of deploying the agent to a dynamic workstation group whose members all have a certain file or files that indicate that they have already received the latest Windows updates. However, I can't see how to create a dynamic group based on such criteria.
    So far I have only updated a few devices at a time using "Deploy System Updates to Selected Devices in the Management Zone". When those updates are done I cancel that deployment because that's the only option I can find that does anything. If you can offer general advice for a better strategy of updating agents I'd appreciate that. Specifically, how would you push an agent update to several hundred computers that will be turned on sometime over the next two weeks?
    Thanks very much.

    To be honest, you have to work around your other deploys, etc. The ZCM agent isn't "aware" of other deploys going on. For example, ZPM doesn't care that you're doing Bundles at the same time (you'll get errors in the logs about the fact that only one MSI can run at a time, for example). ZPM usually recovers and picks up where it left off.
    Bundles on the other hand, with System Update, are not so forgiving. Especially if you have the agents prior to 11.2.4 MU1 (cache corruption errors).
    We usually:
    a) Halt all software rollouts/patching as best we can
    b) Our software deploys (bundles) are on event: user login Typically the system update is on Device Refresh, OR scheduled time, and are device associated.
    IF possible, I'd suggest that you use WOL, system update and voila.
    Or, if no WOL available, then tell your users to leave their pc turned on (doesn't have to be logged in), on X night, and setup your system updates for that night, with the auto-reboot enabled. That worked well
    But otherwise the 3 components of ZCM (Bundles, ZPM, System Update) don't know/care about each other, AFAIK.

  • Best practices for deployment from Dev /Staging /Production in SharePoint ?

    Hi All,
    What is a best practices to deploy SharePoint Portal to dev / staging / Production.
    I have custom solution deployed using WSP file. But I have done some changes using sharepoint designer.
    Like as Designer workflow, master pages etc.
    How can I deploy my document libraries and list to dev to prod using best practices?
    Thanks
    Balaji More

    Hi,
    According to your post, my understanding is that you wanted to know the best practices to deploy SharePoint Portal in different SharePoint environment.
    If the site is not existing in the production server, we can save the site from the development server, and then import it to the production server.
    But if the site is already existing in the production server, we should follow these steps to just add the taxonomy and content types to the production server:
    Save the site from Dev as a template
    Import the template as solution in Visual Studio
    Remove unnecessary items from the solution(Please pay more      attention on it. If a content type/list... in the solution is existing in      the production site too, it will replace the
    same object existing in the      production after deployment)
    Package the solution
    Deploy the solution in the production
    For more detailed, please see:

  • What is best practice for conditional rendering?

    i have a set of radio buttons that conditionally render another set, which in turn conditionally render a 3rd set.
    i am doing this by using a valueChangeListener on an h:selectOneRadio
    when i click yes on the 1st set it renders the 2nd set.
    when i click yes on the 2nd set it renders the 3rd set.
    when i click no on the 1st set now it correctly removes the 2nd & 3rd sets, the method also nulls the values.
    when i click yes on the 1st set, it renders the 2nd set with the old values even though they were nulled. and i can see in the debugger they are still null.
    so there seems to be an issue updating the model, but i dont know what that issue is. im sure it just has something to do with the way i am trying this conditional render. please see below for my first field and my valueChangeListener method.
    any help with what is a best practice for this scenario would be greatly appreciated.

    Thanks in advance

    Similar issue is covered and explained here: [http://balusc.blogspot.com/2007/10/populate-child-menus.html]. Not sure if it solves your problem as you're using ajax4jsf whereas I don't, but it might give new insights. To the point you might need to bind the component(s) and use setValue(null) or setSubmittedValue(null).

  • What is best practice for dealing with Engineering Spare Parts?

    Hello All,
    I am after some advice regarding the process for handling engineering spare parts in PM. (We run ECC 5)
    Our current process is as follows:
    All materials are set up as HIBE's
    Each material is batch managed
    The Batch field is used for the Bin location
    We are now looking to role out PM to a site that has in excess of 50,000 spare parts and want to make sure we use best practice for handling the spare parts. We are now considering using a basic WM setup to handle the movement of parts.
    Please can you provide me with some feedback on what you feel the best practice is for dealing with these parts?
    We are looking to set up a solution that will us to generate pick lists etc and implment a scanning solution to move parts in and out of stores.
    Regards
    Chris

    Hi,
    I hope all the 50000 spare parts are maintained as stock items.
    1. Based on the usage of those spare parts, try to define safety stock & define MRP as "Reorder Point Planning". By this, you can avoid petty cash purchase.
    2. By keeping the spare parts (atleast critical components) in stock, Planned Maintenance as well as unplanned maintenance will not get delayed.
    3. By doing GI based on reservation, qty can be tracked against the order & equipment.
    As this question is MM & WM related, they can give better clarity on this.
    Regards,
    Maheswaran.

    Hi adil,                      
    Based on your description, you want to know the best practices for search service in a SharePoint farm.
    Different farms have different search topologies, for the best search performance, I recommend that you follow the guidance for small, medium, and large farms.
    The article is about the guidance for different farms. 
    Search service can run with other services in the same server, if condition permits and you want to have better performance for search service and other services including BI performance, you can deploy search service in dedicated server.
    If condition permits, I recommend combining a query component with a front-end Web server to avoid putting crawl components and query components on the same serve.
    In your SharePoint farm, you can deploy the query components in a WFE server and the crawl components in an application server.
    The articles below describe the best practices for enterprise search.

  • New mac - what is best practice for accounts?

    I am about to get a new mac (imac g5), and would like it to work well (ie file transfer and backup to from) my existing powerbook.
    Is there a best practice for account set up? should I use the same accounts between the two or can I set up a new account on the new mac?
    Related to this: what will key change sync give me? does that only work with the same accounts on two macs?
    thanks
    John

    With Tiger there is a migration assistant that will move everything over from your Powerbook to your new iMac G5. All you need is a firewire cable and when prompted in your first start-up select migration assistant and connect the two computers. You will need to boot up your Powerbook holding down the 't' key before you connect the two together. Good luck, Jack.
