Load balancing & Fail over with 10g

Hi all, I understand that 10g offers a framework that allows a web site to run on multiple jvm's, therefore, offering load balancing and failover facilities. I can't find detailed information about this though on Oracle's webSite.
If you know of any good documentation about this, please let me know.
Thanks!

  • Load balancing / fail over

    Dear forum,
    Is there an other and more simple / "cheaper" way for load balancing / fail over then using RAC ? E.g. starting more instances againts the (same) database ?
    Thanks in advance,
    Michel

    The answer would be highly platform and version dependent.
    On several platforms you have software implementing a 'shared nothing cluster'. This means you failover complete services to a second server, which is usually dormant.
    There is HP Service Guard, Suncluster, IBM HACMP, and Microsoft cluster, which are or can be configured as shared nothing clusters.
    For Microsoft there was or is, depending on version, Oracle Failsafe, on top of a MS Cluster.
    RAC can be configured in a shared nothing mode too. RAC itself is essentially active/active.
    On the other side, you can of course buy a second server, and use Dataguard to set up a standby database.
    For a physical standby database, which isn't enabled for more than 10 days, you don't pay a license.
    Setting up multiple instances on a single server is obviously not going to work. Those instances need to coordinate what they are doing. This is essentially the task of RAC.

  • Load Balancing and Failover with 10G Standard Edition

    Hi,
    I am new to Oracle Replication and need some help setting up replication for load balancing and failover. Is this possible using Oracle 10G Standard Edition? I plan on having all updates done on the master site and both databases will be for reads. In case of failure of the master site, I would need to be able to failover to the other database.
    Also, if anyone knows of any documention for Basic Replication in 10G, please let me know.
    Thanks.

    Simple nnapshot replication of data would require significant manual effort to configure to load balance or failover. One the load balancing side, you would generally be limited to to static load balancing-- assigning half the users to one machine and the other half of the users to the other machine, regardless of who is actively using the machine. Failover would be a significant manual effort, particularly to bring the failed machine back into the cluster. You would be implementing the guts of multi-master replication.
    Frankly, if you actually have a system which is valuable enough to need load balancing and disaster recovery, I'm going to wager that it will be far cheaper even in the short run to buy more boxes and/or enterprise edition licenses than to try to implement this sort of thing yourself. In the long run, it will be far cheaper, since it will be far easier to maintain. Building all this yourself would probably be penny wise and pound foolish.

  • Load balancing failed to find a valid mailbox database.

    While trying to create new mailbox, the following message is displayed:

  • Load Balancing Forms Services with an effective healthcheck

    I am in the process of configuring two forms 11.1.2 servers running with weblogic 10.3.5 with multiple forms applications clustered across both physical servers. We are looking to load balance to the various forms applications using a hardware load balancer. Can anyone comment on their experience with setting up effective application healthchecks using either hardware or software load balancers?
    For example say that we have 3 applications clustered across 2 servers with the following
    URLs:
    http://server01:7777/forms/frmservlet?config=myapp1
    http://server01:7777/forms/frmservlet?config=myapp2
    http://server01:7777/forms/frmservlet?config=myapp3
    http://server02:7777/forms/frmservlet?config=myapp1
    http://server02:7777/forms/frmservlet?config=myapp2
    http://server02:7777/forms/frmservlet?config=myapp3
    We would need a checking mechanism on the load balancer that could tell if myapp2 was down on say server01 and therefore block traffic to that application yet keep traffic open for the other 2 apps on the same server.
    A specific difficulty with forms is that when the database behind the application is down forms services will return an error message within a displayed error form. From the load balancer's point of view the forms services are "up". We need to find a way of detecting that the application is actually available and not just that the forms services themselves are available. To detect that the forms services are available we might normally use the status check:
    http://server01:7777/forms/frmservlet?ifcmd=status
    however this will only tell use the availability of the forms services on a physical server and not whether any actual applications are available.
    I am aware that f5 do a BIGIP offering that includes some Oracle Forms specific components. Can anyone comment on how they have setup Oracle Forms healthchecks using various load balancing methods. In particular if a load balancer is limited to using WGET commands to check HTTP returned content is there a way of checking a forms application's availability and if not how have other people achieved an effective healthcheck?
    Many thanks,
    Philippe

    Did you ever Get this to work?
    I am having some problems trying to load balance with Oracle Forms, Discover and reports Oracle Application Server Release 10g (9.0.4.0.2) and I was wondering if you could help. Has any one ever got this to work consistently? We are an ERP product written mostly in forms (904) and are trying to implement are largest customer there performance issue so we need the load balancing to work. Will also accept other recommendation as cost effective as solutions.

  • Cluster (Load balancing) implementation in obiee 10g

    Hi All,
    We need to implement clustering (Active-Active for Load balancing) in our project. We use both analytics and bi publisher. We also need to deploy analytics/bipublisher in to weblogic server for SSO purpose.
    Now we have two machines.
    As of now We did the installation of obiee10g (while installing we selected "Complete" button) in both machines. Could any body tell us how to implement clustering w.r.t to weblogic.
    To proceed futher we need to know..
    +1. Did normal clusrtering method in 10g with oc4j server differs when we deploy application in weblogic server..?+
    +2. Can I use any of the two machines to create a shared folder and place rpd to give the path in REPOSITORY_PUBLISHING_DIRECTORY or should I use third machine other than these two machine..???+
    Any help is greatly apprciated.
    Thanks & Regards,

    Hi User,
    Did you configured clustering wrt to OC4j or WLS..?
    A. Weblogic.
    2. Can you tell me how it differs wrt WLS..??
    A. We can't explain here please refer the following link.
    http://www.iwarelogic.com/2010/01/supply-chain-management-w-r-t-oracle-applications-312/
    http://docs.oracle.com/cd/E23943_01/upgrade.1111/e10126/wls_oc4j_comparisons.htm
    3.On top of these two machines we have a virtual IP?
    A. You can use virtual Ip's.
    In your project Weblogic also clustering mode am I write?
    What could be the process.. First we need to follow the clustering method as if there was no WLS and later deploy the application and need to do the changes wrt to WLServer (or) First we need to deploy the application in WLServer and for clustering need to do changes in/wrt to WLServer..??
    A . First we need to deploy the application in WLServer and for clustering need to do changes in/wrt to WLServe.
    Note: As per my knowledge please implement this way.
    1. Deploy analytic.war in your weblogc.
    2. If it is possible please implement Weblgoc clustering also.
    3. SSO implementation.
    4. Cluster implementation.
    This is the way am implemented in my project.
    My project tool details.
    1. Weblogic
    2. OBIEE 10.1.3.4.1
    3. Oracle 11g
    4. OS - AIX
    If you have any concerns please post me.
    Award points it is useful.
    Thanks,

  • Load Balancing Directory Servers with Access Manager - Simple questions

    Hi.
    We are in the process of configuring 2 Access Manager instances (servers) accessing the same logical LDAP repository (comprising physically of two Directory Servers working together with Multi-Master Replication configured and tested) For doing this, we are following guide number 819-6258.
    The guide uses BigIP load balancer for load balancing the directory servers. However, we intend to use Directory Proxy Server. Since we faced some (unresolved) issues last time that we used DPS, there are some simple questions that I would be very grateful to have answers to:
    1. The guide, in section 3.2.10 (To configure Access Manager 1 with the Directory Server load balancer), talks about making changes at 4 places, and replacing the existing entry (hostname and port) with the load balancer's hostname and port (assuming that the load balancer has already been configured). It says that changes need not be made on Access Manager 2 since the LDAPs are in replication, and hence changes will be replicated at all places. However, the guide also states that changes have to be made in two files, namely AMConfig.properties, and the serverconfig.xml file. But these changes will not be reflected on Access Manager 2, since these files are local on each machine.
    Question 1. Do changes have to be made in AMConfig.properties and serverconfig.xml files on the other machine hosting Access Manager 2?
    Question 2: What is the purpose of putting these values here? Specifically, what is achieved by specifying the Directory server host and port in AMConfig.properties, as well as in serverconfig.xml?
    Question 3. In the HTTP console, there is the option of specifying multiple primary LDAP servers, as well as multiple secondary LDAP servers. What is the purpose of these? Are secondary servers attempted when none of the list in the primary list are accessible? Also, if there are multiple entries in the primary server list, are they accessed in a round robin fashion (hereby providing rudimentary load balancing), or are other servers accessed only when the one mentioned first is not reachable etc.?
    2. Since I do not have a load balancer setup yet, I tried the following deviation to the above, which, according to me, should have worked. If viewed in the HTTP console, LDAP / Membership / MSISDN and Policy configuration all pointed to the DS on host 1. When I changed all these to point to the directory server on host 2 (and made AMConfig.properties and serverconfig.xml on host 1 point to DS of host 2 as well), things should have worked fine, but apparently Access manager 1 could not be started. Error from Webserver:

    [14/Aug/2006:04:31:48] warning (13937): CORE3283: stderr: ... 2 more
    In effect, AM on 1 did not start. On rolling back the changes, things again worked like previously.
    Will be really grateful for any help / insight / experience on dealing with the above.
    Thanks!

    Update to the above, incase anyone is reading:
    We setup a similar setup in Windows, and it worked. Here is a detailed account of what was done:
    1. Host 1: Start installer, install automatically, chose Directory server, Directory Administration server, Directory Proxy server, Web server, Access Manager.
    All installed, and worked fine. (AMConfig.properties, serverconfig.xml, and the info in LDAP service, all pointed to HOST1:389)
    2. Host 2: Start installer, install automatically, chose Directory server, Directory Administration server, Directory Proxy server, Web server, Access Manager.
    All installed, and worked fine. (AMConfig.properties, serverconfig.xml, and the info in LDAP service, all pointed to HOST2:389)
    3. Host 1: Started replication. Set to Master
    4. Host 2: Started replication. Set to Master
    5. Host 1: Setup replication agreement to Host 2
    6. Host 2: Setup replication agreement to Host 1
    7. Initiated the remote replica from Host 1 ----> Host 2
    Note that since default installation uses abc.....xyz as the encryption key, setting this to same was not an issue.
    9. Started webserver for Host 1 and logged into AM as amadmin.
    10. Added Host 2 FQDN in DNS Aliases / Realms
    11. Added http://HOST2_FQDN:80 in the Platform server (instance) list.
    12. Started Host 2 webserver. Logged in AM on Host 2, things worked fine.
    At this stage, note the following:
    a) Host 1:
    AMConfig.properties file has
    com.iplanet.am.directory.host=host1_FQDN
    and
    com.iplanet.am.directory.port=389
    serverconfig.xml has:
    <Server name="Server1" host="host1_FQDN" port="389" type="SIMPLE" />
    b) Host 2:
    AMConfig.properties file has
    com.iplanet.am.directory.host=host2_FQDN
    and
    com.iplanet.am.directory.port=389
    serverconfig.xml has:
    <Server name="Server1" host="host2_FQDN" port="389" type="SIMPLE" />
    c) If one logs into AM, and checks LDAP servers for LDAP / Policy Configuration / Membership etc services, they all contain Host2_FQDN:389 (which makes sense, since replica 2 was initialized from 1)
    Returning back to the configuations:
    13. On Host 1, login into the Admin server console of the Directory server. Navigate to the DPS, and confgure the following:
    a) Network Group
    b) LDAP servers
    c) Load Balancing
    d) Change Group
    e) Action on-bind
    f) Allow all actions (permit modification / deletion etc.).
    g) any other configuations required - Am willing to give detailed steps if someone needs them to help me / themselves! :)
    So now, we have DPS configured and running on Host1:489, and distributing load to DS1 and DS2 on a 50:50 basis.
    14. Now, log into AM on Host 1, and instead of Host1_fqdn:389 (for DS) in the following places, specify Host1_fqdn:489 (for the DPS)--
    LDAP Authentication
    MSISDN server
    Membership Service
    Policy configuation.
    Verified that this propagated to the Policy Configuration service and the LDAP authentication service that are already registered with the default organization.
    15. Log out of AM. Following the documentation, modify directory.host and directory.port in AMConfig.properties to point to Host 1_FQDN and 489 respectively. Make this change in AMConfig.properties of both Host 1 as well as 2.
    16. Edit serverconfig.xml on both hosts, and instead of they pointing to their local directory servers, point both to host1_FQDN:489
    17. When you start the webserver, it will refuse to start. Will spew errors such as:

    Success!
    The server https-host1_FQDN has started up.
    The server infact, didn't start up (nothing even listening on 58080).
    However, if AMConfig.properties is left as it originally was, and only serverconfig.xml files were changed as mentioned above, web servers started fine, and things worked all okay. (Alright, except for some glitches when viewed in /amconsole. If /amserver/console is accessed, all is good. Can this mean that all is still not well? I am not sure).
    So far so good. Now comes the sad part. When the same is done on Solaris 9, things dont work. You continue to get the above error, OR the following error, and the web server will refuse to start:
    Differences in Solaris and Windows are as follows:
    1. Windows hosts have 1 IP and hostname. Solaris hosts have 3 IPs and hostnames (for DS, DPS, and webserver).
    No other difference from an architectural perspective.
    Any help / insight on why the above is not working (and why the hell does the documentation seem so sketchy / insecure / incorrect).
    Thanks a bunch!

  • Load Balance HTTPS servers with redirection

    Hello,
    I have been tasked with ACE configuration at work as the prior go-to guy for load balancing is no longer available. Trouble is, I have little idea what I’m doing when it comes to the ACE. So, forgive me if the question I have is super basic. After doing some research I put together a LB config, but its not working.
    I was trying to load balance 10 servers, split into groups of 2 using 5 VIPS (1 VIP for each group of 2 servers). The servers serve an ssl web app.
    Below is my configuration. What am I doing wrong? Does the config have any glaring errors? I've been staring at this thing on and off for a week  and searching these forums trying to figure it out.
    Any help provided will greatly appreciated.

    Fnu,
    Thank you so much for your reply.
    At this point I can get to the real server IP's via ping and https in a browser from my PC. I can also ping the gateway and all the real server IP's from the ACE context i'm working on. However, the VIPS are not working. When I attempt to use one of the VIPS in the browser, the request times out. When I issue the command ":show service-policy"  I see a hit count (which increments every time I try and reach the VIP via the browser) but the dropped counter is equal to the hit counter. I will paste the running config from the context I’m working in along with the output from the show service-policy command.
    Any suggestions on how I can get this working would be greatly appreciated.

  • Load balancing outgoing mail with 3 outgoing servers

    We are trying to balance our mail out with 3 separate mail servers from our incoming server. Our organization sends alot of mail and we wanted to balance it with 3 outgoing SMTP servers. We have them all working, in the zone for the primary DNS and incoming mail server. And we can get mail to go out on the three servers, BUT and this is a problem if the mail includes any messages to the network (hence the incoming server) then the SMTP servers complain they cannot find it and give a error message about not being able to connect to deliver any local mails out of the bulk mail we send. Any ideas how to get the SMTP to see the incoming mail server (which is the DNS server for network) and deliver mail to accounts on the network? Maybe we are doing something that OS X SNL server cannot do? Any ideas.
    I will post the error message later but I need to leave for meeting for now.
    Thanks
    Russ

    Here is error message we get:
    Mar 17 21:34:45 mailout1 postfix/smtp[32307]: connect to mail.vineyardil.net [173.161.44.97]:25 Operation timed out
    Mar 17 21:34:45 mailout1 postfix/smtp[32307]: DE90A1AF591: to =<[email protected]>, relay=none, delay=23732, delays=23701/0.01/30/0, dsn4.4.1, status=deferred (connect to mail.vineyardil.net [173.161.44.97]:25 Operation timed out)
    To explain mailout1 is the first one in priority of outgoing separate SMTP servers we set up in the zone of mail.vineyardil.net which is the DNS server. They send out ok all outgoing mail to other addresses as we wanted them (rather than having mail.vineyardil.net do it) but when we send to an address with vineyardil.net on it then we get this same message.
    It seems like mailout1 cannot send to the incoming server. Note the ip address it gives is the ip of the cable modem on this network not the ip address locally in the net we have.
    Our MX records all look good and things work with mail if we use it both as incoming and outgoing (SMTP) but when we use the secondary servers for outgoing they seem to not be able to send to this server. Is there something we should look for?
    Is SL server not capable of what we are trying? Any feedback would be most appreciated. We would like to really use this setup as I explained to do load balancing of mail as part of our attempt on this new network to get our bulk mailing split up between the 3 outgoing servers so we will not be labeled spam by the security systems out there these days like it was on our old network.
    Thanks for your time.

  • Load Balancing Internet Sources with WSA

    Hello everyone,
    Is is possible to have multiple internet sources with the WSA like Microsoft Forefront TMG you can have multiple internet sources and adjust for example 33% load on the first link and 66% percent on the second link .
    We currently have the S160 .
    Thanks .

    If you mean "use the WSA to load balance traffic between 2 or more internet providers", no... the WSA won't do that.

  • Load Balancing Linux servers with CSS 11050 series

    We would like to load balance Linux FTP and Web servers with a CSS 11050 series device. Does the content switch use SNMP to load balance the servers? If so, which MIBs need to be loaded on the servers?

    I dont believe that the CSS supports any SNMP load balancing mechanism.
    There is basically two factors involved in load balancing. One: the state of the servers which can be done via a range of mechanisms including ping, TCP connection, Application request, etc. Two: the way a server is chosen when a request comes in including round-robin, least connections, ACA etc.

  • OSB 10gR3 - Create load balanced endpoint URI with WLST

    Hi,
    I need to create load balanced endpoint URIs for a Business Service listening to a JMQ queue. The configuration can be done through the console as shown below:
    Protocol: JMS
    Load Balancing Algorithm: round-robin
    URI 1 - jms://localhost:7001/loggingXACF/loggingQueue
    URI 2 - jms://localhost:7002/loggingXACF/loggingQueue
    I would like to do the same using ALSB customization API in WLST. Any pointers on this would be helpful
    Regards
    Vikas

    Any one have any idea what a CLUSTER-BROADCAST message is? And where it would be coming from?Cluster broadcast message is one of the way by using which WebLogic Server instances in a cluster communicate with one another. Details are here -
    http://download.oracle.com/docs/cd/E14571_01/web.1111/e13709/features.htm#i1021836
    Having little idea about this, I may not comment on the exact reason behind 21.4 million CLUSTER-BROADCAST messages in 70 minutes, but you may get better and faster response in Weblogic clustering forum -
    WebLogic Server - Clustering
    If you have Oracle Support, then I will suggest you to track this throgh a SR.

  • Load Balance Configuration for OCS 10g

    Hi guys,
    A few question on the load balancer requirement and setup for a OCS 10g cluster.
    1. Can Pound be used as the load balancer for the OCS cluster. (pound is an application for load balancer and reverse proxy).
    2. Basically the load balancer will have two network interface, the first nic is connected to the
    user network, and the second interface is connected at the backend network where the ocs cluster is located. My question is at which network interface the virtual server name (ldap, sso and http ) for the ocs cluster should be created ? at the user network interface or the ocs network interface ?. Do the virtual name need an ip addresses ?
    Thanks for any info.
    Regards

  • "Load report failed" error with VS 2010 upgrade

    I have a report system that has been running nicely for a few years. Today, I upgraded it to use the latest Crystal from Visual Studio 2010. I installed the .net framework 4.0, installed the Crystal runtime (64 bit), and updated the web site with slightly revised code to use the new stuff. Now, reports that worked yesterday fail with the 'load report failed' error. A little research shows that the file name passed to the report engine is correct (and is the same as it has always been). I see that rpt files are being created in windows\temp each time a report is requested, so it seems that the report file is being found.
    The code change I made was to use the new ExportToHttpResponse method.
    When deployed in development and test environments (both 32 bit). this worked perfectly. In production, however, no such luck. I wonder if I have missed a setting somewhere, or if there is something extra to do on a 64 bit server?
    Does anyone have a clue for me?
    More info - I found the following error in the event log:
    The keycode assembly, BusinessObjects.Licensing.KeycodeDecoder.dll, cannot be loaded.
    ... which I thought was interesting until I noticed the same error occurs on my dev machine, where the reports are working.
    I also used process monitor to check the dlls loaded on the production box, and they all seem to be the latest version. I tried using the 'modules' utility on my production box, but it did not pick up the Crystal stuff (or any of my web stuff - I wonder if it is a 32-bit only tool?).
    Edited by: Ray Novak on Dec 29, 2010 5:12 PM

    I just tried this again with the same result. I uninstalled the previous Crystal, deleted all the old folders and reg keys I could find, then installed the new 64 bit redist package. I asigned permissions to the SAP reg key tree. I ended up with the same result: "Invalid file name". There were new files created in the temp folder for each report request, so I can tell that my.rpt files are being found.
    I used process monitor to see what was happening, and here are the results that seem interesting:
    RegOpenKey     HKU\.DEFAULT\Software\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0     NAME NOT FOUND          
    RegOpenKey     HKU\.DEFAULT\Software\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0     NAME NOT FOUND

    Since it seemed to be trying to create files in the \win64_x64 folder, I allowed the process full access, but it didn't help. It was also looking for SmAgentAPI.dll which does not seem to exist on my system.

  • Client Load balancing in AS with RAC

    Friends,
    1. Is an application servers cluster supports client load balancing.
    If not....
    2. if RAC is configured with appplication servers:
    client -> appl sever -> rac_node -> shared database
    is there a possibility to configure CLIENT load balancing with the aid of any of the above
    components (or smth else that i missed) i.e. avoid using hardware client load balancing
    or third party software client load balancing???
    Thanks much for help.

    Hi, I have the same question.
    I am using RAC (11.1.0.7) and would like to load balance two application servers in the same way, for apache, forms and reports using 10.2.0.4 iAS FAR.
    If I could load balance the apache connection, I'm sure it would be simple from there, again, I only have software load balancing available.
    Could you point me to a doco?
    Thank you very much.
