OEL 5.5, Clusterware and cross site clustering

Guys,
Just wandering what solutions others have in place when clustering applications (not oracle db's) through clusterware across multiple sites. Our standard with other clustering products is to create a host based mirror, effectively mirroring the application data across disks at both sites and using the cluster to fail over the vip and application in the event of a DR.
Other clustering products on Linux all seem to have integration with LVM2 to provide split brain protection (IO fencing/locking) but clusterware does not. Oracle have suggested using ASM to create cross site mirrored volumes but we are not keen on the idea of using ASM to manage volumes on non-database servers (conflict of interest with support of volume management between sys admins and dba's).
thanks,
Richard

However, the latest versions of Clusterware all create ASM volumes for this.

  • Data Guard Broker and Cold Failover clusters

    Hi,
    I wanted to use Data Guard Broker to control primary/standby systems on AIX clusters but found that without Oracle clusterware it is not supported on failover of a database to another node (unless you drop and recreate the configuration which in my opinion is not support at all!).
    The 11g documentation states that DG Broker offers support for single instance databases configured for HA using Oracle Clusterware and "cold failover clusters".
    Does anyone know whether this support for cold failover clusters in 11g means "proper support" i.e the configuration detects that the hostname has changed and automatically renames it so it continues to work?, or is the support in 11g the same as that in 10g?.
    Thanks,
    Andy

    Hi Jan,
    We already use virtual hostnames.
    When I set up the configuration the hostname for the databases default to the server name. The only way I know of changing this is to disable the configuration, then use the "edit database...set property" command but when I enable the configuration again it reverts back to its previous value.

  • Cross Site collections navigation with publishing feature enabled into sharepoint 2010??

    Hi,
    Is it possible to cross site collection navigation in share point 2010 with publishing feature enabled? Right now we have a site collection with all the departmental sites within it. We are trying to create separate site collection with separate content
    database for each department for better management. But problem with Global navigation as OOB does not provide cross site collection navigation functionality, So looking for multiple site collections or navigation for more than one site collection under single
    umbrella. i was able to get the cross site collection navigation in my development env without publishing feature enabled using below link. But problem with production environment, as all the site collections and sites are publishing feature enabled. how i
    am gonna do cross site navigation with publishing feature enabled? 
    http://www.itsolutionbraindumps.com/2011/10/sharepoint-2010-cross-site-collection.html
    Any link or suggest will be greatly appreciated !

    Hi,
    According to your description, my understanding is that you want to create cross site collections navigation with publishing feature enabled in SharePoint 2010.
    Publishing sites (sites with publishing infrastructure) have their own navigation API, and it is much more complicated task to preserve cross-publishing sites navigation.
    We need to implement our own custom navigation provider.
    Please refer to the link below about the cross site collections navigation with publishing feature enabled:

When I go to those pages within the pdf file in Adobe Reader, I get the error: "There was a problem reading this document (114)."
    Can you verify this problem on your end. Also, how do I get a good copy of this document?

  • JSF 1.2 and CSRF (Cross Site Request Forgery) protection

    Hi All
    My webapp uses (among other technologies like JSP, Ajax, Dojo etc) JSF v1.2 on Webshere 7.0.
    I've been fixing security issues in the code recently - in particular Cross Site Request Forgery (CSRF) vulnerabilities. The suggested approach to combat CSRF is to embed a hidden unique token in your form (and also store this same token in the session). In the controller logic (i.e that handles the form's POST) we then check that the session and request token match. I've used this in my JSP's to combat CSRF successfullu. Basically I have a filter which executes before the form loads. This filter creates the unique token and stores in request and session and so on ..
    Now for JSF 1.2 ...
    I'm wondering how I do this in JSF v1.2 ? Would any one have an code samples or resource they could point me towards ? Is there a filter mechanism we can employ or some callback on the post ?
    One idea I had is that to populate to form with the hidden token I would do (in the form):
    <h:inputHidden id="jsfSecurityToken" value="#{myBean.securityToken}"/>
    In "myBean.java" I have a getSecurityToken method which
    a) creates the token
    b) stores it into the request
    c) stores it into the session
    BUT I don't know how/where on the post I can CHECK if these values match
    Page 40/41 of http://turbomanage.files.wordpress.com/2009/10/securing-jsf-applications-against-owasp-top-ten-color.pdf mentions "isPostBack" but I'm not sure how to use this.
    Any help would be great
    Thanks - Ronan

    A phase listener comes to mind. Check out this useful article:

  • SQL Server 2012 Multi-Site clustering with 2 nodes for HA and DR

    Usually we setup 2 Node Prod cluster for Local HA and 1 or 2 Nodes in other data centre for DR
    Given that we have an option to setup multi-site / multi-subnet clustering from SQL 2008 R2/2012. I am planning to use just 2 nodes, 1 in prod data centre and 1 in DR data centre with 2 or 3 instances. This will act as both HA and DR solution.
    I would like to know if this solution is good, and any disadvantages, any best practices, etc.? By implementing this I can save some cost on physical servers.
    Following will be configured:
    * Will be using different subnets, quorum on different server with "Node and File Share Majority"
    * All virtual IPs will be registered for virtual name, and Subnetdelay, Subnet threshold will be modified accordingly
    * All nodes on same domain
    * Use SAN Disk with replication to DR site

    SQL 2008 R2 doesn't support multi-subnet clustering. You would still need 3rd party component like VLAN and Disk Replication. SQL 2012 is the first version to support multi-subnet clustering without using VLAN. you would still need disk replication hardware/software.
    Taken from my book
    Since nodes are often located in two different data centers at geographically dispersed locations, there is no shared storage between the nodes in a multi-site cluster. Clustering across two different data centers provides a higher level of availability and
    protection at the storage level as we have more than a single copy of the data.
    For SAN replication technology implemented in such clusters, the main activity is to keep data replicated between the sites. Typically, if we have nodes on two different sites, we would have two different network infrastructures and the nodes would be in
    different subnets. In such cases, if we are on a SQL Server version before 2012, we need to use third party VLAN (Virtual LAN) technology so that one IP address travels between two sites. This is called wide-IP. Companies hesitate with this solution because
    of the need to buy a third party solution to deploy the VLAN. Using VLAN technology means the same IP address would failover to the remote site in case of a local site disaster. Network administration might consider this as an overhead to maintenance and an
    extra piece of the networking component that needs to be secure.
    With SQL Server 2012 we do not need to use stretch VLAN technology but SAN replication is still needed for multi-site clustering. The OS version for this can be from Windows Server 2008 R2 and above. In this deployment, we can have a SQL virtual network
    name having an “OR” dependency on two different IP addresses. One address would be representing each subnet. With the “OR” dependency, if IP1 or IP2 is online we just use the network name. This is one of the Enterprise Editions only features.
    Other option which you can think of, without using 3rd party solutions would be AlwaysOn Availability Group. I have written details about it in my book.

  • LiveCycle ES2, Guides, SSL and IE 8/9 Cross Site Scripting Issue

    I have a guide that is being served up in the workspace.
    This guide works fine in all of the different browser versions provided they go through port 8080.
    If however you enable SSL on your server (port 8443) and serve up the guide in the workspace, the end user can fill the entire form out only to have the browser identify the submit process as a Cross Site Scripting issue.
    This is the result:
    The data is essentially lost and guide disappears.  I had a theory that maybe the submit process might be using the default server port for data submissions (8080) and created a customized submit process with the hardcoded targetURL.
    I tried to test my theory and got the same result.  I then modified my custom submit process to essentially do nothing (Started and ended the process with an abstract activity), and got the same result.
    The only other thing that I could think of, is that the automatically generated action script classes might be hard coded to use default port instead of the SSL port.
    Suggestions?!

  • Cross Site Publishing and Variations: how to manage assets?

    We have a Cross-Site Publishing scenario:
    - an Authoring site collection with variations enabled, in order to manage content in English and Italian
    - two Publishing site collections
    - an Intranet Site Collection
    Intranet and Web site are feeded from Authoring site collections.
    We have some assets (Video and Photos) with their own metadata (title, description, ...) that we need to localize in each Language.
    We followed TechNet best practices: we saved these assets in a separate site collection with Anonymous access enabled.
    Where do we have to compile metadata?
    In a list in the Authoring site collection where we build an entry for each digital asset we want to describe (of course, a list in each variation site)? Or is it better to associate metadata in the Asset Library (in this case how we manage translations)?

    Did you find a solution for this issue? I have the same problem. Thank you very much

  • Utilities Applications grayed and crossed out, "No longer supported"?

    Originally I wanted to Verify and Repair my Disk Permissions since I've been having difficulty with my disk drive [playing the Sims 3, it told me that there was an error in the Disk Authorization and that the disk was not found in the drive]. Following the instructions on the Sims 3 site to fix this problem, one solution would work then it would fail again so I continued down the line of fixes until it told me that "Its possible you might  be experiencing some damage in your permissions or an issue with your start up disk please follow these steps below." Then proceeded to tell me how to verify and eventually repair which entailed going to the Utilities folder and opening the app "Disk Utility". But when I got to the Utilites folder I found that all of the application icons where grayed out and crossed out in white. When I attempted to open any app a window would tell me, "You can't open the application <app name> because PowerPC applications are no longer supported.
    Now I found a question/discussion nearly identical to this, only it was in the Leopard discussions, and I obviously have Lion. The one reply on this subject suggested two things, both of were not options for me and the other user with this problem. Link: https://discussions.apple.com/thread/1826047?threadID=1826047
    I have no idea what to do at this point, I just want my Mac to work for once and let me play my **** Sims.
    If it helps, I have a MacBook Pro, mid 2007, with many different applications installed, I recieved it as a hand-me-down two years ago and I'm not so familiar with all of the applications, so I couldn't begin to tell you what exactly is on here.

    PPC apps won't run in Lion. Sorry that you missed that small detail before upgrading.

  • DOM Based Cross-Site Scripting issue in RoboHelp 10

    We're using a WebHelp system originally deplyed using RoboHelp 9.0.2.271, and a recent security scan revealed the DOM based cross-site scripting issue.
    I recently upgraded to RoboHelp 10, migrated my help system to this version, and redeployed the system, but our security scan is still detecting the cross-scripting vulnerability in WebHelp. Wasn't this issue resolved in RoboHelp 10?
    Thanks

    I’m not a security expert, but this script reads the URL of the current topic and redirects to the current topic with a bookmark. This is needed for when the same topic is used in multiple locations in the TOC.

  • Cross-site scripting vulnerability RoboHelp 10 version

    Has the cross-site scripting vulnerability been addressed in the RoboHelp 10 version

    To the best of my knowledge it was addressed in Rh9. Rh10 has an HTML5 output option that does not use frames.
    However, if security is a concern, then only a security expert can give you the assurance you require.
    Personally I have yet to hear of webhelp being used maliciously but that does not mean it hasn't happened.

    You can patch this yourself :) The regular expressions that
    are used by
    the Global Script Protect function are located in the
    neo-security.xml
