Oracle Weblogic Load Balancing/Clustering

Can anyone tell me what the recommendation from Oracle is on how to best set up load balancing?
We currently use the configuration.properties file to identify the 2 servers we load balance.  We will be implementing additional servers in the near future and we were wondering if this is the best way to load balance 4 or more weblogic servers or if there is some other way.
We set up one cluster address to utilize these servers and use a separate hardware load balancer device.
HRDEV\webserv\hrdev\applications\peoplesoft\PORTAL.war\WEB-INF\psftdocs\hrdev\configuration.properties
# To enable jolt failover and load balancing, provide a list of application server
# domains in the format of;  psserver=AppSrvr:JSLport,...
# For example:  psserver=SERVER1:9000,SERVER2:9010,SERVER3:9020

As this is peoplesoft specific configuration

  • Setting up Load Balancing / Clustering in BIP installation

    Hi,
    We're upgrading Siebel 7.8 to 8.1.1.5. As part of this process, we'll be replacing the two clustered Actuate Servers with two BI Publisher installations.
    We need BIP to behave like for like compared to Actuate (clustered / load balanced) but I cannot any detailed instructions on implementing Load Balancing / Clustering of BIP anywhere.
    We use a Loadbalancer.org appliance to balance the Siebel URL - my plan is to use this to support load balancing of the Web Services across the two BIP instances. However, I also need the two BIP installations to share the same repository.
    I've come across an Oracle White Paper (http://www.oracle.com/technetwork/middleware/bi-publisher/bip-cluster-deployment-366859.pdf) that states:
    The repository is shared among different servers in the cluster
    However, looking at the installation guide for Oracle BIP 10.1.x.x.x, there are no details on how to achieve this.
    Anyone know where to find documentation explaining, in detail, how to load balance multiple BIP servers to achieve the same level of high availability as we had with Actuate?
    Thanks in advance!

  • Session Stickness problem on weblogic load balancer

    Hello All
    I having trouble related to session stickiness for weblogic load balancing, am using httpclusterservlet on a proxy server that forward requests to 3 managed server that are members of the same cluster.
    I tried to search for a solution to this problem and I found two links that are talking about the same problem but there are still not answered!!.
    Here are the links:
    https://forums.oracle.com/message/11158966#11158966
    https://forums.oracle.com/message/11158964#11158964
    Based on oracle link Using Sessions and Session Persistence, the documentation says under the "HTTP Session Properties" section that there is a change in how the sessions are formatted and this might cause a problem
    for some load balancers (the documentation did not say if weblogic httpclusterservlet is one of them), I tried to do the suggested workaround and I got "java.lang.IllegalStateException: Response already committed" error same as what happens with the user in link https://forums.oracle.com/message/11158966#11158966.
    Does anyone knows how to fix this??, I search for a very long time on this problem and with no luck, please help!

    Hi,
    Can you please give me some more information about your setup ...
    Something like ...
    F5/LB --> Apache or OHS --> WebLogic Cluster..
    If you are using F5/OHS directly to WebLogic cluster you can try enabling the session persistence and this problem should go away..
    If you are using plain Apache or OHS try putting "DynamicServerList" off.
    Let me know something more about setup so that i can contribute to help ..thanks.

  • Weblogic: load balancing and RAC contention

    I cannot locate any useful documentation on this: I am trying to find the optimal configuration to allow an Weblogic Application server to load balance to RAC.
    I see high numbers of v$sqlstats.clwait_delta for sessions connected from weblogic servers; typically from 25-95% over the overall statement execution time.
    Configuration is a three node RAC 10.2.0.4 on Linux; with and eight node weblogic cluster connected using about 150 sessions (equally divided between the rac nodes), hosting a number of applications. They use "Least Connections" load balancing which means any thread(/connection) could be used next. The weblogic sessions connect to a RAC service that is configured with LOAD_BALANCE=YES.
    I suspect that contention is caused by behaviour such as
    - insert on one node, then immediately query back on another node
    - inserts to indexed tables being distributed across all three nodes.
    There is too much going on here, and I want to simplify the configuration to eliminate contention for the same data blocks across nodes - this will likely mean new database services configured with LOAD_BALANCE=NO and some form of application partitioning on the weblogic servers. There are other load balancing schemes available for weblogic; but none seem designed to work well with rac.
    Is there any best practice documentation available to configure weblogic on RAC (as opposed to single-instance, which doesnt have any such contention issues).
    Any pointers appreciated!

  • Oracle Portal Load Balancing question

    Our customer wishes to have multiple Oracle Application Servers running Oracle Portal, with load balancing. They would like to have Web Cache collocated with one of these Portal servers, operating as a load balancer for the Portal servers (including the one collocated with Web Cache). Our understanding is that this is not supported, since Web Cache must use the same port number as the destination server it is load balancing, and this is a problem with collocation. The alternative of using mod_oc4j load balancing by OHS is we understand not supported for Portal. The customer does not wish to use external, hardware load balancers, or operating system load balancing. We understand that the solution is to use Web Cache on a dedicated separate server, to load balance the Portal servers. Can you please confirm that, or is collocation possible to avoid the cost of the dedicated Web Cache server.
    thanks,

  • Oracle RAC load balancing sessions

    Hi Gurus,
    I have just implemented SAP on a 2 node RAC. We had RAC1 shutdown for maintenance, and all sessions were failed over to RAC2. Upon bringing RAC1 up, all the sessions remains connected to RAC2. New sessions are load balance between the 2 nodes. Hence, RAC2 is much busier than RAC1.
    How can I distribute the sessions/load in oracle upon bringing back a RAC node?
    Thanks,
    Tzyy Ming

    Hi,
    >> I am using 11g scan. I have switched all the scan services to RAC1. RAC2 has over 300 sessions. After the entire afternoon, RAC1 only manage to build up less than 100 sessions, while RAC2 still has 300 sessions. Most users are connected to SAP throughout the day. It will be nice if we can average out to 200 sessions on each node.
    You shoudn't expect that a SAP workprocess kills itself and connect to another resource during the runtime, in order to RAC1. So, newly created processes may be connected to the newly startup RAC node. Because of this RAC2 has 300 and RAC1 has 100 sessions on it.
    >> Relocating the service manually requires human intervention and creates human error. How can we configure RAC so that it knows 1 node is busier than the others and automatically redirect the connection to the lighter node?
    As far as I know that this is manual operation, not automatic
    I hope that it is clear

    Thanks in Advance.Create a service for each group, entering that service name in the connect string, and providing those users with the appropriate tnsnames.ora or application.
    You middle-tier could handle this using the correct jdbc connection based on some info retrieved from the database. I will leave it up to you to take the suggestions and figure out how to develop the scenario you described.
    Isn't It is also about time you upgraded to something that is still supported? 11g will make some of these issues a whole lot easier. You CAN use 11g Cluster/ASM with your 10g database until you can get your db upgraded. I have upgraded a boat-load of 10g databases to 11g - always < 2hrs start to finish. In many cases converting from single-instance to RAC in the same upgrade session. YMMV.

  • Oracle RAC - Load Balancing Problem

    Our J2EE application transactions (Container-managed) are using MULTIPLE database connections to complete one business transaction.
    Recently we swiched to below Oracle RAC configuration, and it is creating problems.
    BEA 8.1 SP5 Multi Pools
    Oracle 9i RAC (2 instances) : Active - Active
    Algorithm : Load Balancing
    Driver (JDBC) : Oracle 10g Release 1 Thin Driver
    non-XA transactions
    Looks like when LB algorithm is chosen, the load balacing is only **connection-aware** and NOT **transaction-aware**. Because of this, the application gets one connection from one RAC instance, and other from other instance is creating problems.
    Is there any work-around exist for this problem?
    If we chose, HIGH_AVAILABILTY algorithm, everything is fine. But we would like to make use of both instances.

    ChintalaHi, OK, that looks fine, except:
    1 - I would define the initial and max capacity = 30, for performance and stability.
    2 - For more performance, turn off test-on-release. It's a waste of cycles.
    3 - You can change your TestTableName to "SQL BEGIN NULL; END;" which goes
    even faster than "select 1 from dual".
    And the main problem is:
    4 - Your JDBCDataSource doesn't seem to be a transactional one, so any
    application code that gets connections from that, will get independent
    connections each time, and their work will not be included in any WLS
    controlled transactions. You want to make/use a JDBCTxDataSource.

  • Oracle RAC load balancing advisory services query

    Hi,

    Is it possible to create a service for exeuction of a PL/SQL package?
    We have UNIX batches which are set of PL/SQL packages that may or may not be linked are executed daily. These batches consumes lots of resources.
    So i want to configure my services such that say pkg1 will go to node1 and pkg2 will go to node2 and so on and so forth.

    Hi, my answers are:
    Is it possible to create a service for exeuction of a PL/SQL package?Yes, that is posible, you can create a service for execute PL/SQL Packages, in fact you can create any service that you need and assign the resources and priorities for this service.
    Is it possible to achieve this with Net services and LBA?Yes, thats posible, you define the priorities at service level and where the service must run at node level.
    If not, is there any other way i can do this?Yes, if you dont wish using the LBA and services you will must create statict definition into tnsnames file for operate connection string and indicate where must connect the session for execute the package.
    Luck.

    We are currently using Weblogic domain as a Proxy Plug-In for High Availability test as it’s explained in this blog http://andrejusb.blogspot.com/2009/04/weblogic-load-balancing-for-oracle-adf.html.
    Its working fine for POC project but what software load balancer would you recommended for production environment on Linux? (Assume that we don’t have a hardware load balancer).
    - Oracle active-passive OHS web-tier clustering.
    -Using Linux open source Linux Software(e.g. HAProxy and KeepAlived as explained here http://biemond.blogspot.com/2010/04/high-availability-load-balancer- for.html
    -Using any other software load Balancer
    I would appreciate if anybody can provide some recommendations/links etc.
    Thanks

  • Oracle Applications 11i Load Balancing does not work with RAC one Node

    Hi all,
    Could you help me to resolve this issue.
    Architecture environment is :
    - One APPS tier node
    - Two nodes Oracle Database Appliance (Primary node 1 holds INSTANCE_1 et Secondary node is configurured to holds INSTANCE_2), i.e RAC one Node.
    - The primary node have instance_name SIGM_1 and the secondary node have instance_name SIGM_2, but in RAC one node, the secondary instance is not alive.
    We convert our EBS 11i environment to RAC following note ID Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 11i [ID 823586.1].
    When testing Database failover, Oracle Applications 11i load balancing does not work anymore.
    The root cause is that, when the primary node of the Rac one node is down, the INSTANCE_NAME_1 is automaically relocating to the surviving node,.
    During test failover, we imagine that when the primary node goes down, the secondary node start or relocate database with instance_name SIGM_2, and in that case the Oracle Applications load balancing works.
    Currently, when the primary node goes down, the instance_name SIGM_1 is relocated on the secondary node, which cause failure of Oracle Applications Load Balancing.
    Thank you for your advice.

    This is something I observed a long time ago for Safari (ie: around version 1). I'm not sure this is Safari, per se, but OpenSSL that is responsible for the behavior. I'm pretty sure Chrome does this and I've seen some Linux browsers do it.
    What I have done at the last two companies I've worked for is recommend that our clients do not use SSL SessionID as the way of tracking sticky sessions on web servers, but instead using IP address. This works in nearly all cases and has few downsides. The other solution is to use some sort of session sharing on your web servers to mitigate the issue (which also means that your web servers aren't a point of failure for your users' sessions). (One of the products I supported had no session information stored on the web servers, so we could safely round-robin requests, the other product could be implemented with a Session State Server... but in most cases we just used IP address to load balance with). The other solution is to configure your load balancer to terminate the SSL tunnel. You get some other benefits from this, such as allowing your load balancer to reduce the number of actual connections to the web servers. I've seen many devices setup this way.
    One thing to consider through this is that - due to the way internet standards work - this really can't be termed a bug on anyone's part. There is no guarantee in the SSL/TLS standards that a client will return the same SSL Session ID for each request and there is not requirement that subsequent requests will even use the same tunnel. Remember, HTTP is a stateless protocol. Each request is considered a new request by the web server and everything else is just trickery to try and get it to work the way you want. You can be annoyed at Safari's behavior, but it's been this way for over 5 years by my count, so I don't expect it to change.

  • Oracle RAC Concept  - load balancing

    Hello All,
    I have a question about Oracle RAC and how it balance loading.
    What I know about Oracle RAC that it balancing load between its node, so if a new session is connected to the Database it will execute on the node which have less load.
    If I am having an application that connects to the database with few number of sessions and some sessions have huge (huge load) processes to execute while the other sessions are executing small process (in terms of load).
    So below is an example scenario that i am asking for an answer of it:
    if am having a two node RAC database.
    My application that is connected to this RAC database wants to execute three processes P1, P2 and P3 each will have a session correspondingly S1, S2 and S3
    Let is say that P1 will take 60% of the database resources (memory ....) and P2 will take 1% and P3 1%.
    So my question is it a sessions load balancing or Processes load balancing ? So in case and randomly (Managed by ORACLE RAC) S1 is connected to node 1 and it is using node 1 resources so the load on node 1 will be 60%, so when S2 and S3 needs to connect it will go to node 2 since node 1 is loaded. in that case i will have Node 1 using 60% of it is resources (becuase of S1 that is executing P1) while node 2 only uses 2 % (because of S2 and S3 that is executing P2 and P3).
    Is that how Oracle RAC works ? or it balance the load of S1 (60%) between node 1 and node 2 ?
    I am asking this question since my application is not users application, so it will connect to the database with few number of sessions, and 1 session of them may execute a huge process while the other are executing small processes.
    So in that case, how RAC is doing the balance loading?
    Regards,

    i hope , this links may help you.
