Load Balancing Advisory

hi everyone,
while configuring my TAF service, I checked the option for Load Balancing Advisory through Enterprise Manager. now I want to use the functionality of LBA, I mean from where I can see the Advise or suggestions by LBA, as I dont find this. I want to know about the statistics of loadbalancing and if necessary increase or decrease the load as suggested by LBA on required node. guide me for this through enterprise manager.
its not grid control, its just enterprise manager dbcontorl.

on top what has already been said:
the LBA inner-working look like:
the MMNL bg. process calculate the service metrics and resource consumption based on service goal defined for service.
From this data MMNL derives the service goodness. Further, MMNL forwards the service goodness to PMON.
PMON computes and forward the service goodness and delta to listeners.
MMON computes and posts the LBA FAN events to system queue...and IMON retrieve the event from the queue and post the event to the local ONS daemon. For the mid-tier ONS, the event is sent by server ONS daemon.
If you would like to monitor published LBA FAN events you may check: sys$service_metrics_tab

  • Oracle RAC load balancing advisory services query

    Hi,
    I have a query on RAC load balancing advisory.
    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.
    Is it possible to achieve this with Net services and LBA?
    If not, is there any other way i can do this?
    Thanks

    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.
    Have a good day.

  • Load Balancing with 10g RAC

    Hi,
    I have one query regarding balancing load with RAC.
    We have some batch processes executed from shell script in Oracle RAC environment where a separate node is used for failover only. There are some issues related with performance. We are looking for a solution to utilize 'idle' node used for failover to resolve this issue.
    I want to know whether the below mentioned scenario is possible to achieve with 10gRel2 RAC.
    A batch process is running and it is utilizing all resources (CPU) of instance 1, then it is possible by any means that this process be split and distributed to idle instance 2 on another node?
    Looking for expert advice.
    Regards
    Amit

    Hi Amit,
    I;ve done lots of RAC implementations, and it;s critical to set-up the primary node accordig to the "type" of table access. For example, cistomer queries on node 1, order queries on node 2, etc. Minimizing pinging is very important!
    Staring in Oracle 10g release 2, Oracle JDBC and ODP.NET provide connection pool load balancing facilities through integration with the new “load balancing advisory” tool. This replaces the more-cumbersome listener-based load balancing technique.
    I have more notes here:

  • Load Balancing in RAC

    If you have 2 node cluster , you have configured Node 1 as Preferred instance and Node 2 as available.
    According to Oracle , the service will always run on a preferred instance and will relocate to available instance in case of preferred node failure.
    Also you have server side load balancing, as per documentation the service will relocate on available instance if the preferred node crashes.
    Question: How will Oracle take care of Load Balancing , since the service on available node will only run if the preferred node crashes. Since the service is not running on Node 2 (available instance) ? How will oracle distribute the connections among the nodes?

    The answer to your question depends one the configuration of your Oracle Net Services, Whether you have configured connection load balancing or server side load balancing. Oracle will only balance the workload among the database instance running the service. By default Oracle starts the service on prefered node and in your case you have configured only one preferred database instance for your service and at a time service will run on one node only so Oracle does not have any options to distribute the workload even if you have configured the server side load balancing for the services using the service level goals.
    To explain it further, consider you have 3 node cluster. The database instance on first and second node are preferred instances for the net service and service-level goals are defined for server side load balancing.
    Now suppose second node fails and Oracle relocates the service to third node. Because Oracle is aware about the services running in the cluster even the relocated services (You should read about LOCAL_LISTENER and REMOTE_LISTENER to understand how Oracle register services with listeners on other cluster nodes) thats why using the load balancing advisory Oracle decides, which node the new database connection should be connected.

  • Reg Load Balancing

    Hi,
    How to configure server side load balancing.
    I saw two types Load based and Session based.
    How to specify the options for the both
    I know by setting parameter load_balance=on will enable in tnsnames.ora file.
    whether above parameter enable client side load balancing or server side load balancing
    Suggest me any document which explains both with example.
    Thanks

    Hi Aman,
    Your thoughts on the below Statements.
    Setting the REMOTE_LISTENER parameter has the following effect -
    The PMON process on that node will register with the remote listeners specified in the REMOTE_LISTENER value.
    This means PMON process will update the remote listeners about the work load status on the local node.
    When REMOTE_LISTENERS are set on all nodes, all PMON processes register with all other listeners.
    When the client makes a connection and the connection goes to a specific listener (either using load_balance on or off),the listener that accepts the connection will check the load on all nodes to see which is the least loaded.
    The listener is able to do this since PMON processes from all nodes have updated the listener about the statuses.and that listener will redirect the connection to the node with the least load and start a dedicated process on that node .
    Now how does the PMON know which is the least loaded machine.
    It gets the information from the FAN framework and load balance advisory.
    FAN framework consists the following processes
    MMON,PMON,ONS and AQ. (ONS is specific to Java clients and AQ is specific to ODI.Net clients)
    Load Balancing advisory calculates the goodness of a node and forwards to MMON.
    MMON builds the advisory and forwards it to PMON. And thus PMON is able to update all the listeners.
    Setting the REMOTE_LISTENER parameter has the following effect -
    The PMON process on that node will register with the remote listeners specified in the REMOTE_LISTENER value.
    This means PMON process will update the remote listeners about the work load status on the local node.
    When REMOTE_LISTENERS are set on all nodes, all PMON processes register with all other listeners.

  • Rac load balance

    Dear Gurus
    my database 10.2.0.4 and rac is configured.
    database is working fine.actually rac is installed from last 3 years and database is running fine.
    But when we see cpu usage on both nodes by command sar -r ,cpu usage on node 2 is less than node1
    so my boss is saying that load balancing is not happening.
    Could anybody tell me how could i check whether load balancing is fine on both nodes or is it like some master node concept.
    Please give some ideas to test the same as in my opinion load balancin is working fine but i don't know how do i check it

    Hi
    So, you are trying to achieve uniform CPU usage among the RAC nodes using RAC load balancing techniques?
    I am afraid, answer to your problem is not simple. Do you use Services to load balance? If yes, how is the CLB_GOAL and GOAL (run time) is setup for the services? You could potentially use services and load balancing goal to keep the CPU usage uniform.
    But, this becomes more complex in connection pool environments. In connection pool, connections are created at an accelerated pace. PMON updates the listener with Load Balancing Advisory data every 3 seconds or so, and if the connections arriving within that 3 seconds, then the listener does not get correct LBA and So, the listener might redirect the connection to the node already heavily loaded. You could control the this damage by introducing delays between the connection pool logins in such a way that PMON has enough time to update the listener.
    Even then, In theory, you could have imbalanced CPU usage. For example, let's say that application created 50 connections to instance 1 and 50 connections to instance 2. Now, some part of the application is going to have more CPU usage, then the others. If accidentally, all those connections borrowed by those CPU intensive components, are from one instance, then CPU usage will be higher. I guess, what I am saying is that connection pools do not know underlying instance load and might not distribute the workload.
    I will ask the question differently. Were you able to identify exactly what is causing the increased CPU usage in the heavily loaded node? Are you sure that it is the application? If yes, you could potentially configure more services so that you can differentiate the CPU usage at the service level.
    Now, the ultimate question is, do you see this imbalance causing performance issue?
    Hope this helps,
    Cheers

  • Question about FCF and Oracle load Balance

    We have recently set up the FCF and load balance advisory.
    We are using JDBC UCP connection Pool.
    Here is the service name is as following:
    CATEST_FCF =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ptt-pt-ildb-01-vip)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = ptt-pt-ildb-02-vip)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = CATEST_FCF.THECPP.COM)
    (FAILOVER_MODE =
    (TYPE = SELECT)
    (METHOD = BASIC)
    (RETRIES = 180)
    (DELAY = 5)
    -- service goal is SERVICE_TIME and CLB_GOAL is LONG
    -- ons.config
    localport=6101
    remoteport=6200
    loglevel=9
    useocr=on
    I was trying some test as the link below.
    http://drdobbs.com/java/222700353?pgno=1
    but my client is always trying to connect to instance 2 even the sys.sys$service_metrics_tab already showed the instance 1 can take on more load.
    Total held connections: 9
    [0] Instance name [TZNTEST2]
    [1] Instance name [TZNTEST2]
    [2] Instance name [TZNTEST2]
    [3] Instance name [TZNTEST2]
    [4] Instance name [TZNTEST2]
    [5] Instance name [TZNTEST2]
    [6] Instance name [TZNTEST2]
    [7] Instance name [TZNTEST2]
    [8] Instance name [TZNTEST2]
    (CATEST_FCF, VERSION=1.0 database=CATEST service=CATEST_FCF { {instance=CATEST1 percent=88 flag=GOOD}{instance=CATEST2 percent=12 flag=GOOD} } timestamp=2011-04-12 11:59:36)
    am I correct here? the percent for CATEST1 is 88. Does it mean CATEST1 is able to take on 88% more load, so it is more attractive now?
    and why the connections always fell on CATEST2? How does oracle calculate the number of connections to each instance. Does it count inactive or killed session too? does it offer the load balance stats based on total number of connections on each instance or total number of connections just to this serivce on each instance?

    I don't know if this helps, but there is a reply comment from
    Macromedia at the bottom of the MX 6 LiveDocs for tag
    cfprocparam
    which was in response to a comment pointing out that calling
    overloaded stored procedures containing refcursors did not work. (I
    submitted a similar question to Adobe last night in the MX 7
    version of LiveDocs for cfprocparam and am waiting for it to post.)
    Macromedia jrunrandy said on Jun 30, 2005 at 9:45 AM :
    I checked and regret to say that this isn't supported. There
    is a bug for this issue,
    53122, but it hasn't been addressed as of CFMX 7.
    I think that this is going to be as official of a response
    from Macromedia/Adobe as you are going to get unless you open a
    trouble report yourself. I hope that this is enough to satisfy the
    requirements of your DBA. Otherwise, you are probably going to have
    to shell out the cash for an official trouble report to Adobe

    Is your backend system configured correctly in your SLD ?
    Go to transaction SMMS on your backend system that your are connecting to. Click on Goto=>Parameters=>Display. Look for "server port" value.
    This should give you the TCP/IP port for your message server. It could be 3600 or 3601 (36NN - where NN is the instance number).
    In your services file, if you made the entry at the end of the file, press Enter (Return) after your entry.
    Try restarting your server after making the above changes.

  • ISE 1.2 - Multiple NICs/Load Balancing for DHCP Probe

    Hello guys
    Just prepping an ISE 1.2 patch 8 setup in our organization. I am going for the virtual appliances with multiple NICs. It will be a distributed deployment with 4 x PSNs behind a load balancer and there is no requirement for wireless or guest user at the moment. I've got 2 points I will like to get some guidance on:
    Our DC has a dedicated mgmt network and I plan to IP the gig0 interface of the PANs, MNTs and PSNs from this subnet. All device admin, clustering, config replication, etc will be over this interface. However, RADIUS/probe/other user traffic to the ISE PSNs will be over the gig1 interface which will be addressed from another L3 network. Is this a supported configuration in ISE?
    I intend to use the DHCP probe as part of device profiling and will ideally like to have just an additional ip helper to add to our switch SVI config. Also, it will appear that WLCs can only be configured for 2 DHCP servers for a given network so another consideration for when we bringing our WLAN in scope. We however use ACE load balancers within our DC and from what I have read, they do not support DHCP load balancing. Are there any workarounds to using the DHCP probe with multiple PSNs without having to add each node as an ip helper/DHCP server on the NADs?
    Thanks in advance
    Sayre

    Hello Sayre-
    For Question #1:
    Management is restricted to GigabitEthernet 0 and that cannot be changed so you should be good there
    You can configure Radius and Profiling to be enabled on other interfaces
    Even though you are not using guest services yet, you can dedicate an interface just for that. As a result, you can separate guest traffic completely from your production network
    Take a look at this link for more info:
    http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/installation_guide/ise_ig/ise_app_c-ports.html
    For Question #2
    If you are using a Cisco WLC and running code 7.4 and newer you don't need to mess with the IP helper configurations. 
    The controller can be configured to act as a collector for client profiling and interact with the DHCP thread along with the RADIUS accounting task that is running on the controller. The controller receives a copy of the DHCP request packet sent from the DHCP thread and parses the DHCP packet for two options:
    –Option 12—HostName of the client
    –Option 60—The Vendor Class Identifier
    After this information is gathered from the DHCP_REQUEST packet, a message is formed by the controller with these option fields and is sent to the RADIUS accounting thread, which is in turn transmitted to the ISE in the form of an interim accounting message.
    Both DHCP and HTTP profiling settings are located under the "Advanced" configuration tab in the WLC
    On the other hand, you can also use Anycast for profiling. You can check out some of Cisco Live's sessions for more info on that. Here is one that is from a couple of years (There are more recent ones that are available as well):
    http://www.alcatron.net/Cisco%20Live%202013%20Melbourne/Cisco%20Live%20Content/Security/BRKSEC-3040%20%20Advanced%20ISE%20and%20Secure%20Access%20Deployment.pdf

  • SAP GLM Print Request - Load Balancing of WWI server

    Hi GLM Experts,
    I am using new GLM + module that generates labels based on Print Requests. I am unable to understand how I can load balance the WWI services when there are multiple label printing requests.
    In GLM + we associate a WWI to a Print Station and which can then be associated with a printer. So in the configuration we are tying up a printer a WWI.
    Also during label printing, if the scenario uses print request module, then the use need to select a print station and printer. What happens if the WWI related to the print station is down?
    For example I have two services in WWI server GENPC1 and GENPC2. I created WWII and WWI2 as two print stations. I will associate my printer PRNWWI to both the print stations WWI1 and WWI2.
    During label printing if the user picks and WWI1 and Printer PDNWWI and if the GENPC1 WWI server assocaited with print status WWI1 is busy and down I want WWI GENPC2 to generate the label?
    How to setup the above load balancing or fall back? Please let me know.
    Thanks
    Pugal

    Dear Pugal
    we are not using GLM + and I am not sure about the technqiue used there to handle load balancing. Regarding general WWI setup I assume you know this Note: EH&amp;amp;S: Availability and performance of WWI and Expert servers
    On the top there is a further SAP Note abvailable which might be of interest. This is referenced here:
    http://de.scribd.com/doc/191576739/011000358700000861002013-e
    May be check OSS note: 1958655; OSS Note 1155294 is more related to normal WWI stuff; but may be check it as well. May be 1934253 might help better
    May be this might help.
    C.B.
    PS: may be check as well: consolut - EHS_MD_140_01 - EH&amp;amp;S-Management-Server einrichten
    The load balancing of synchron WWi servers is donein the "RFC" layer, therefore you have no inffluence here, for asynchron WWI servers you can do a lot to manage the WWI load balancing by using "exits" etc.

  • APEX SSO and Load balancing: Could not determine workspace for application

    We had a single HTTP Server serving APEX in a 10.2.0.2 database configured with SSO to be used by the developers. APEX has been registered as a partner application and the login url has been CA Siteminder protected so that the SM_USER details are forwarded in the header for the application to use for authorization. Everything is fine so far.
    Now we have added a HTTP Server on another host and have it all set up for APEX and its pointing to the same database. APEX_ADMIN access works as normal, but applications previously using SSO now get the following error after entering the URL.
    Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
    Error ERR-7620 Could not determine workspace for application ().
    Using HTTP Watch I find that the application is not even trying to redirect to the login page.
    What is wrong here?

    APEX has been registered as a partner application as described in
    http://www.oracle.com/technology/products/database/application_express/howtos/sso_partner_app.html
    In the meantime I found metalink document 368746.1 which describes the cause of this problem. Please read carefully what I wrote, it all works when the the new APEX web server is turned off in the server farm on the load balancer and directed through the original web server. When running regapp.sql the hostname in the listener token was using the virtual hostname. This works fine if the request comes from the original APEX server which proofs that there is nothing wrong with the installation and set up of SSO. When directing the request to the new APEX web server the APEX_ADMIN page still works only existing work spaces using SSO don't seems to work anymore resulting in a error as described in the subject.
    As for metalink document 368746.1 naming the causes of this error:
    - there are no duplicate entries in WWSEC_ENABLER_CONFIG_INFO$
    -LISTENER_TOKEN clearly works for requests coming from the first web server
    -theoretically the web server listener port could be changed from 7777, but port 80 needs to be maintained here as production is mimiced as far down as possible.
    Is there some cache table which can be cleared? How is it that the flows schema (apex engine) can not find the work space when the request comes from a new web server which can however access the APEX_ADMIN pages.
    anyone?

  • SSO with SAP R/3 with load balancing as backend over the Web AS

    Hi,
    we have Netweaver 2004 at this time and we have to connect the portal to a BSP application in a load balancing environment.
    We set user mapping for the user and set the connection type from SAPLOGONTICKET to UIDPW. This is running for a test environment with only one R/3 system without load balancing.
    Does anyone know the setting parameters for a load balancing environment (ok, the message server and...?).
    Thank you.
    Best regards
    Patrizia

    Hi all,
    run into the same problem. Setting up a mapping with UIDPW in a non load balanced WEB-AS enviroment for BSP or Webdynpro for ABAP works fine. But if I go to set it up in a balanced system I can see the following behavior. The http request is send to the messageserver. This request enclosed my mapped user and password. The messageserver responds with an HTTP 301 wich contains one of my applicationservers, so far so good. The client sends a new request to the mentioned applicationserver but this time without the UIDPW. So the user will not be logged in.
    I was wondering if my backend have to issue logonticket too, cause today it only accept tickets from the portal.
    Is this is a bug or a feature?

    Bernd

  • How to change the OraSSO login link in webcache/load balance

    Hi
    we have 10gAsR1 installed as a Portal instance. We have 6-server
    load balancer => webcache as loadbalancer (listening port 80)
    Wb ch1 and wb ch2 => webcache (listening port 7777)
    portal1 and portal2 => Portal listening 7778
    infra =>Infrastruture with repository Portal/Oracle SSO (listening 7777)
    This set up is working fine for our intranet setup, now we need to open this for couple of external clients. Well initially we need to open on the load balancer server on port 80 for external team to access, it works fine when we make it publc access.
    Now when we need to make it SSO (siteminder) enables, when users click on login link it first goes oracle sso then it internally redirects the page to site minder sso.
    Well, I have noted that the sso server details are mentioned in global setting sso/oid details. Since we need to open this for external client we have to add a DNS entry for this so that we can allow its access over firewall..
    Now I have made DNS name change at my infrserver level, now I need to update the change at the load balancer server (where wheb chache is running).
    Any one know how to chang the URL at load balancer.
    I am struck at this point please suggest how should i proceed..
    Thanks,

  • DS to BW load balancing

    Dear all,
    I have a doubt regarding load balancing in PRD. Our team is loading data through DS 12.2.2.3 to SAP BW Master / transaction Infosources.
    SAP BW system has five Application Servers / instances to balance the load. BW target data store is configured to connect to the Central Instance of SAP BW.
    Since we are connected to the Central instance / application server of BW system from DS, will BW system be able to balance the load across multiple instances?
    Since BW Server has multiple instances to balance the load, is there any way we can utilise these BW multiple instances from Data Services?
    Can you share your thoughts on this? Appreciate your responses.

    Hi Suneer,
    There are several ways how DS and BW can interact, so it might depend on what scenario you are using.
    I can think of the following scenario's:
    1. A DS job is executed from admin console and loads into a BW target datasource.
    This should use any available server, according to load balancing settings. It is not possible to force the process to use a specific server.
    2. A process chain starts an infopackage, which in turn starts a DS job
    BW will use the server chosen at the time of scheduling, if everything is configured correctly and scheduled correctly it will use any avaialble server conform load balancing settings. You can set this to run on a specific server (but I would only recommend this in very special circumstances).
    3. DS triggers a process chain
    Again, BW will use the settings on the process chain.
    4. BW runs an execution command, which starts a DS job
    Well, this is not a relevant scenario as it does not update anything on BW - unless the execution command then runs a job which loads data into BW, which is described in scenario 1.
    I hope this makes sense. Let me know if you have any other scenario's or concerns.
    Can I just ask why you are concerned about this load balancing? I have not have load balancing problems with DS/BW but I have had plenty of problems around concurrent use of the RFC connection between DS/BW. 'Multithreading' was not supported until 12.2.3.2 and you mentioned you run on 12.2.2.3, so potentially this is a problem for you.
