What type of changes require server restart?

Hi,
We are trying to minimize downtime for applications and re-design our deployment process. One of the questions is what type of changes require weblogic restart and which would require only re-deployment of application server.
Is there a document which would detail actions required by type of changes in config?

Hi,
There are basically two types of changes we can make in WLS...
*1). Dynamic Changes:* It means the Changes which doesnt requires Server Restart. Like Updating/deploying/undeploying applications. Creating DataSources, Creating Users in SecurityRealms, Configuring WorkManagers.
*2). Non-Dynamic Changes:* These are the Changes which requires Server Restart ... sothat the changes can take affect. Like: Activating another SecurityRealm as Default realm, Changing cluster Multicast Address, Configuring Startup/Shutdown classes, Changinf ClassPath or Java_options from AdminConsole for ManagedServers using ServerStart Tab, Adding/Removing Managed Servers from Machine...etc.
There is not such link available which lists all the Non-Dynamic & Dynamic Changes. Even AdminConsole also displays sometimes Wrong Message ...sometimes for few Non-Dynamic Changes as well it says "No Restart Required" But actually we had to start it.
Thanks

  • Portlet:namespace val changes on server restart. How to keep it constant?

    Hi -
    I want to generate WinRunner test script, and want to know the IDs of a couple of UI components on a JSF JSP.
    But JSF prefixes each component id with <portlet:namespace/> value. So, I tried to prefix the same value (got it using view source of the actual screen to test) to the components in my test script.
    This works just fine, the way I want it to, but until the server is not restarted.
    Once the server is restarted the value of the <portlet:namespace/> changes (for the same view in same jsp), thus my test script doesn't work.
    Is this expected behavior that for the same view in jsp, the value of <portlet:namespace/> changes after server restart?
    Is there a way to keep the value of <portlet:namespace/> constant for the same view even after server restart?
    Expecting prompt feedback and will highly appreciate it.
    Thanks
    Gagan

    The problem is still there if the jsp file is about inserting a new record
    into the database.
    If these parameters are gotten from the session, mutliple insertings will be
    attempted when the portlet is refresh.
    Maybe we can put some control flags in the session to judge the correct
    behavior, but the method results the session full of parameters(control
    flags).
    Or is there any better design?

    Alan,
    You could use the session to put your parameters in instead of letting itride completely
    on the request object. Although, your question is more than just makingthe content
    reappear, it’s about holding state. The project that I am working on, theusers
    decided that they want the page portlets to go back to the "normal" state,not the
    "Maximized" view. So, I put a processor in between the internal.refreshwildcard
    and the Preprocessor input processor so that all the portlets would beseen in their
    "normal" state.
    Good Luck

    Hi All,
    When I click page tabs in WLP, it will trigger a refresh event.
    The portlet has a webflow with a refresh event whose destination is
    lastContentUrl(referent-namespace is portal, cloned from portlet2.wf).
    The question is when the page changed, the jsp files which use
    request.getParameter() to get parameters will fail to fulfill what they
    need because the event provide none parameter.
    So that everytime page changed, these portlets will have quite strange
    contents.
    How to keep these content constant when page changed?
    Sincerely,

  • Reimport model requires server restart for version nw 04s sp15

    Hi All,
      Does reimport of model requires sever restart in NW 04s sp15, Sometimes it works with out restart of server. .Please give your inputs.
    Thanks.

    Hi,
    The J2EE engine holds a cache of deployed model objects that is optimized by technical system.
    Therefore if there are updates in the metadata of a deployed model object, it is necessary to restart the J2EE engine to flush this cache, and make the new interface metadata available to the Web Dynpro application.
    Its not always required to restart the server.Its only required when there are updates in the model object.
    Thanks n Regards,

  • What types of things require reprompt for refresh of display?

    BAM streaming table seems to require "reprompt" for the data to actually show up. I am using 10.1.3.3 BAM. The data comes from BPEL BAM sensors. Some of it shows up without clicking reprompt, other types require I click that button. If I wait for it, I have to wait a long time (many minutes), if I reprompt it shows up right away.
    It seems that "inserts" show up right away, upserts/updates are late and/or require reprompt.
    anybody else see this, or now how to fix it?

    No reprompts are required with BAM.
    The Streaming List is optimized for Inserts only. So you need to use the Updating Ordered List in order to see updates and upserts.
    Summary for the 3 types of List Views
    * Streaming List - only inserts
    * Updating List - only updates
    * Updating Ordered List - inserts, updates & deletes

  • Does changing SXMB_ADM - RUNTIME- HTTP_TIMEOUT requires server restsart?

    hi forum,
    i want to change the
    SXMB_ADM -> RUNTIME->HTTP_TIMEOUT value,
    does it requires server restart?
    I mean to say, if i change this paramter, will it come into effect immediately, without restating any XI server component,
    pls help,

    Hi Sudeep,
    Server restart is not required after changing http_timeout as far as I know.
    It should be effective immediately.

  • Why WSUS installation on WS2012 R2 fails with message indicating server restart required?

    Dear all,
    I've trying to install WSUS server role on WS 2012 R2 standard. Server is domain joined, and local SQL server (SQL Server 2008 R2 with SP3) installed. This SQL server is to host the WSUS database.
    WS 2012 R2 is fully patched. Nothing else is installed on this server except SQL server mentioned above. I initiate WSUS role installation, specify that WIS is not required, rather WSUS database is required, database connection to locally installed SQL server
    is established; which succeeds without any problem, but when wizard starts WSUS role installation it continues to fail over and over. It indicates in server manager task view that role installation failed because the server require restart.
    I restarted server several times, repeated the process but this continues to behave like this. 
    Why WSUS installation on server fails repeatedly? 
    Why log should be examined or any other dependency is missing here? 
    Please advise.
    Regards,

    Hello Steven,
    Thanks for the input, in fact I did mention server name to pick SQL server instance from, since the only instance configured is default instance locally on the server where I'm trying to install WSUS on. 
    When Add Roles/Features selection wizard gets to WSUS configuration; it asks for location where updates will be stored, next it asks to connect to SQL server to use for SUS database; that's where I specify local server's host name (in my case HQCAS) and
    click "Check connection" this succeeds without any error. 
    All these steps proceed without any problem, but later on, WSUS role installation fails. I also checked CBS.log file; but it didn't give any specific clues? The only message I receive is that role installation requires server restart.
    I reboot server; start all over, but the behavior remains the same. Since WSUS role did not get install in the first place, it won't be possible to check event viewer for WSUS related events. Moreover...wsusutil.exe tool will also be not available until
    after successful install. 
    I couldn't reach any post deployment. Had a look at that link you forwarded, the
    update mentioned in below area also doesn't apply since I specify the local server's host name and then click "Check connection". This steps goes without any error.  Any other insight would be greatly appreciated.
    Regards,
    Shahzad

  • Xdodelivery Changes - Server restarts required?

    I am currently using EBus 12.1.3 (XML Publisher 5.6.3)
    I have changed some settings in the xdodelivery.cfg file located under $XDO_TOP/resource.
    I have bounced the application server but the entries in the xdo.log files I am generating still reflect the previous xdodelivery.cfg file settings.
    What other servers need to be restarted in order for the new settings to take effect?

  • Is there a  requirement to restart the JMS/Weblogc Server everytime when the DB goes down?

    Question:
    When the Database is shutdown gracefully everything was fine.
    But when the Database is brought down with shutdown abort the MDB consumer will never consume messages from the topic again. And we need to restart the WebLogic Server in order to get the messages consumed again.
    So is there a requirement to restart the JMS/Weblogc Server everytime when the DB goes down? If not, what type of failures will require the JMS/WLS restart?

    On a DB failure, a WL JDBC store service will make a brief attempt to reconnect before shutting itself down along with any services that depend on the store. 
    It isn't necessary to restart the entire WebLogic Server JVM to bring the affected service(s) back if you can use the Automatic Service Migration feature.  ASM can automatically restart a failed service on a different WL Server in the same cluster, and/or can try a restart-in-place for the service if the service's original host WL Server JVM is still running.   The Automatic Service Migration (pdf) white-paper has a thorough discussion of this area.
    In addition to ASM, there's also a "whole server migration" option that can automatically restart or migrate an entire WL server.

  • What are the ports required for the Audio, Video and A/V conferencing when the following end points are enabled for QoS in Lync 2013 server?

    Hi All,
    What are the ports required for the Audio, Video and A/V conferencing when the following clients are enabled for QoS in Lync 2013 server?
    Client Type
    Port range  and Protocol required for Audio
    Port range and Protocol required for
    Video
    Port range and Protocol required for
    A/Vconferencing
    Windows Desktop   Client
    Windows mobile App
    Iphone
    Ipad
    Andriod phone
    Andriod Tablet
    MAC desktop client
    Please advise. Many Thanks.

    Out of the box, 1024-65535 for all of the client ports.  :) 
    https://technet.microsoft.com/en-us/library/gg398833.aspx
    You'll want to tune your client ports a bit
    https://technet.microsoft.com/en-us/library/jj204760.aspx as seen here, and then the client ports would use those ranges which is easier to set QoS markings.  I'm not sure the mobile clients respect that setting.
    Elan's got the best writeup for Windows clients here:
    http://www.shudnow.net/2013/02/16/enabling-qos-for-lync-server-2013-and-various-clients-part-1/
    However, the marking of the packets is the tricky part.  Windows can do it via Group Policy, but for the other clients you'll need to have the network specifically prioritize ports regardless of DSCP markings.  You have to do it based on ports
    as the traffic could be peer to peer.

  • Send for shared review - What type of Web server folder works?

    Hello all,
    Can someone please explain to me what type of web server folder works with "Send for shared review"?
    I have created a folder on my GoDaddy server account with full permissions... http://webservername.com/Adobe_Test but after clicking Next, I see the error, "The Shared Folder Location is not valid. Click OK and check the Status field for more information."
    1) It isn't valid? What are the valid server requirements?
    2) "...check the Status field for more information."? What Status field?
    It would have been great if I could use a Google Docs folder but that failed as well.
    What must I do to unlock this neat feature?
    Thank you

    Thanks CtDave.
    I ended up building a WebDAV server and I am now encountering a bunch of new issues. Such as:
    From my workstation, working with Acrobat.
    - After making comments. I click the top button "Publish Comments" - this works well - no errors. But when I attempt to exit the PDF, Acrobat wants to save the document. Attempting to Save results in a read-only error. After trying this, Acrobat gets into a loop where there doesn't appear to be a way to exit Acrobat (other than by Save As new file name):
    Even worse... I understood that reviewers only required the Adobe Reader in order to comment. This doesn't seem to be the case.
    When I emailed a test document for review, this is the message that pops up:
    All that is available is the original content (none of the review comments are available).
    Any ideas?

  • Purpose of Changing Requirement Type by User processing Sales Order

    Hi,
    What could be the reasons for a user processing sales order to change requirement type in the sales order.......as we know that requirement tyor has only one requirement class assigned......so with the change of requirement type, requirement class also gets changed, which is essentially an object controlled by Production folks.....I want to undestand why has SAP given this option where in the user porocessing the document can change the requirememt type.....an you let me know possible scenarios.....
    Thanks
    Satish Talikota

    Sure.
    The possible requirement types are controlled normally via the planning strategy group in the material master.
    In there you can have more than one strategy, which in turn leads to the possibility to change them in the order.
    There can be many scenarios, lets look at one; I normally sell from stock (MTS) a certain material, but from time to time I receive large orders that require a certain modification/customization of the product, so I can't sell the ones that I have in stock, and need to specificaly manufacture (MTO). In this case I change the requirements from MTS to MTO for these orders only.

    what key(s) do it type to change language from english to other? i am writing a story in dual languages. I was told to click command and space bar together but it is not working.

    Command Spacebar opens Spotlight as you have found out. If you want to change languages you need to say what app you are using to write the story in, I'm guessing you are using Pages or MS Word. If that's the case
    Pages: Open Inspector - Click the T tab - Click Language and change your language.
    MS Word: Tools Menu - Language - Choose your language.
