Database Analysis -Load balance.

Hi Experts,
There is new db onboraded in our existing database server in upcoming few week. I would like to know what are the thinng we need to check in the terms of CPU and memory utilisation from new database prespective. for example how many ad-hoc queries being
fired on on server etc..
If you can give me pointers that would be great.
Shivraj Patil.

For load test, you can see the below link.

For system resource monitor, you shall do it from server end.
For trace SQL Server events, you can use the
SQL Server Profiler.

  • JDBC load balancing with non RAC replicated instances

    Hi,
    The thin JDBC load balancing feature only works with RAC clusters or it can be used with two non RAC replicated instances using the same service name?
    Thanks,
    Ezio.

    Thank you Douglas for your time.
    I assumed the first case (database connection load balancing). I thought that the listener would do the load balancing and failover trick. So, I configured the JDBC connection as follow:
    String MM_loadBalance1_DRIVER = "oracle.jdbc.driver.OracleDriver";
    String MM_loadBalance1_USERNAME = "scott";
    String MM_loadBalance1_PASSWORD = "tiger";
    String MM_loadBalance1_STRING = "jdbc:oracle:thin:@(DESCRIPTION=" +
    " (LOAD_BALANCE=on) (FAILOVER=on)"+
    " (ADDRESS_LIST="+
    " (ADDRESS=(PROTOCOL=TCP)(HOST=test1) (PORT=1521))"+
    " (ADDRESS=(PROTOCOL=TCP)(HOST=test2)(PORT=1521)))"+
    " (CONNECT_DATA=(SERVICE_NAME=test)))";
    Driver DriverRecordset1 = (Driver)Class.forName(MM_loadBalance1_DRIVER).newInstance();
    Connection ConnRecordset1 = DriverManager.getConnection(MM_loadBalance1_STRING,MM_loadBalance1_USERNAME,MM_loadBalance1_PASSWORD);
    But, when one of the instances was down (test1), the connection failed, it didn't failed over to the other instance (test2).
    So I wondered if it failed due to some misconfiguration issue or because it only works with RAC instances...

  • Load-balancing with OCI connections

    Gurus,
    Oracle Identity Federation (OIF) can leverage an Oracle database as its transient data store in which case it uses JDBC-OCI connections to connect. However, there is no provision in OIF of defining multiple databases for load-balancing purposes.
    Is this achievable using some load-balancer in front of multiple database instances and using a virtual hostname/IP in tnsnames.ora which OIF refers to?
    -Vinod

    I would say that using two seperate databases (with replication)
    as the backend would mean that one database, at any time,
    might be lagging the other, depending on which tables are updated
    and how replication is implemented.
    Connect Time Failover, rather than Load Balancing, might be an
    implementation -- to handle Instance Failure (eg node / site has gone down).
    Instead of Load Balancing.
    Load Balancng between two seperate databases would be usable
    if you are sure that either of
    a. The underlying data doesn't change
    OR
    b. The application and users are aware that they might see different data
    if there ARE changes to the data, not yet synchronised between the two DBs.

  • OID and Load Balancing

    I have tried to start 2 instances of OID pointing to a same database...

    Try to take down any oidldapd can't do it must kill -9.
    Question:
    --Do this means that only 1 oidldapd per database.
    --What happens if i must load balance.
    --Do i need to replicate??? the databases for load balancing???

    Hello Jaime:
    Im not sure if you are starting your instances of OiD properly. Let me first give you a definition of the oidctl command options your using and see if that straightens things out for you.
    The first part of your oidctl command has connect=ifgpc.com
    It appears that you are entering the incorrect connect information here. The connect information should be the same as your database sid name. For example, if your database sid is oiddb1 then your connect infomation should look like:
    oitctl connect=oiddb1
    In your command you used connect=ifgpc.com
    This looks like the fully qualified domain name of your machine and not a database sid name. If this is true, this is not the correct informtion for your connect string.
    The next part of your oidctl string is correct (server=oidldapd). If you needed to start second process of the same name on the same database instance, then you would need to modify your instance to read "instance=2".
    It appears to me that you are trying to startup two instances of OiD on the same machine. This is not the way to do it. I would recomend that you be on the machine you are trying to start and not try to start both instances from the same machine.
    oidctl connect=local_oid_sid server=oidlapd instance=1 start
    You cannot have two instances of OiD running on the same machine with the same port number (ie 9950) and the same sid. These things must be unique to each instance unless they are on seperate machines. If this doesnt help please give me more details of how each instance of OiD is setup.
    thanks,
    Jay

  • Load balancing on rac database with single node appsTier

    Hi,
    Please advice me, I am working on to configure load balancing on appstier, following is my setup and steps I did so far.
    Host name      Services
    Clelx062ptlge --     Rac 1 – only database
    Clelx063ptlge --     Rac 2 – only database
    Clelx042ptlge --     All apps services including concurrent managers
    I have two R12 database(UDEV -- development & HRQA -- UAT), I only made changes in apps tier xml file of udev for some load balancing parameters, following are the changes I did.
    *<TWO_TASK oa_var="s_tools_twotask" osd="unix"> udev_806_BALANCE </TWO_TASK>*
    *<CP_TWOTASK oa_var="s_cp_twotask" customized="yes">udev_806_BALANCE</CP_TWOTASK>*
    *<TWO_TASK oa_var="s_weboh_twotask" osd="unix"> udev_BALANCE </TWO_TASK>*
    I changed the values from "UDEV" to given above value. After the above change I ran autoconfig. Then Concurrent managers and forms services are not automatically getting failover to second database node, I need to bounce services to fail it back to other available Rac node. Please note that we have only one appsTier
    Thanks,
    Tanveer Mohammed.

    Hi,
    Yes, i have checked the doc referenced, and already did the steps given in the doc. Also i did all the steps given into ID 388577.1 but still Concurrent managers and forms services are not automatically getting failover to second database node, I need to bounce services to fail it back to other available Rac node.

  • Load balancing between application server and database

    Hi,
    is there any load balancing between the application server and the database? Consider we have a single instance of an application server that sends database queries from different clients to the database. Are the requests queued in some way at the application server, allowing to control the flow of the queries (e.g. queries from "more important" clients might be sent with a higher priority)?
    Thanks for your help!

    Hi Victor/Jim/Volker,
    Thanks a lot for all the responses..
    Just wanted to let you guys know that my installation finished successfully.
    The thing which confused me was that my Qtime, Qdate and everything else was showing correct values..
    Well, my problem I set the environmental variable PASE_TZ to the EST time zone on a SYS level using WRKENVVAR>F4>SYS and added the variable. I logged off and the sidofr logged off, but one user which should have logged off and didn't was the "SAPINST"(my installation user) which was logged in the subsystem TMKSVR00.
    Even when I had closed the SAPINST installlation program, the user doesn't log off...it just sits there until and unless u shut him out of the system using the option 4 on wrkactjob for ending the JOB(SAPINST logged in the system below the TMKSVR00 subsystem)
    So since the SAPISNT user never logged of, his environmental variables were not initilized properly, even after the changes...
    This thought came to me almost after a 6 hours of wasting my time searching for notes here and there...
    I think when u end/stop the install in SAPINST, the SAPINST user should log off the AS400 system, but I have noticed, it never does...although when u restart the installation, if u have noticed it shows you the log on for the SAPINST user in the TMKSVR screen...
    Its kind of buggy, I would say...
    I have noticed, that even when I log on to AS400 from home or from a remote PC using Emulator, it shows me logged in the subsystem and even after i have logged of, it still shows me there...
    Anyway, thanks a lot guys...for all your responses..
    Just wanted to let you know all.
    Thanks

  • Load balancing multiple SSO mid-tier with single SSO database

    I want to load balance SSO middle tier servers and have them access a single SSO database. When you install infrastructure and select SSO only it creates a new infrastructure database. How can I install multiple SSO servers and point them to a single database. I am doing Load Balancing with F5 and read an Oracle WP where they mentioned an Oracle supported configuration where they load balanced SSO servers with F5.
    KB

    Two possible solutions:
    1.) Oracle 10gAS Enterprise Deployment Guide (B13998-03) follow the configuration for SSO configuration in Chapter 5.
    2.) I have not tried this but it should be logically possible with the SSO. 10gAS Administrators guide (B13995-05) Part III Advanced Administration. The success of this method assumes you have OID and SSO each installed in separate homes. You would be cloning the SSO home to another box as if it were a middle tier (it is still part of the infrastructure) then re-configuring it on the new box.
    Personally solution 1 is the best method. We are using F5 Big-IP with this configuration and it is working great.
    Hope this helps!

  • Database Native web services - load balancing,  Instrumentation , security

    Hello –
    I’m proposing use of Database Native web service in our company. Our architects are asking following questions so appreciate your help
    a.     How do you load balance across the DB WS (is there a way to use the F5 to detect downtime and balance the load across the DB servers)? We will be using RAC configuration with 3 nodes.
    b.     Our architect have security concern as user id/password information are in the web service URL, which may prove to be an issue. Is there a way to mitigate this risk?
    c.     Instrumentation in this approach (db native services) is questionable due to development/auto gen of the service logic from the DB itself. We may investigate wrapping the services with OSB to give us an additional instrumentation, policy enforcement, endpoint mediation and security proxy. Thoughts??
    d.     Architect are curious regarding any potential performance issues this may have on the DB server.
    Thanks

    Hi
    We've recently begun using Native Web Services, intending to roll out this approach across the enterprise, but we've encountered 2 significant problems so far, which you may want to consider before proceeding ...
    1. NWS returns an exception if the underlying PL/SQL returns a null value - even if the PL/SQL has completed successfully, and null is a legitimate return value (see SR 3-6201969101 - it contains simple instructions to recreate the problem)
    (I raised it in this forum but there were no replies - SOAP Fault when returning null from a Native Web Service Stored Procedure
    2. The sequence of values returned in the NWS response message is the opposite to the sequence declared in the auto-generated wsdl - i.e. schema validation will fail (see SR 3-6209016991 - it also contains simple instructions to replicate)
    We have coded a workaround for problem 1. where we return <EMPTY> in place of null, and check for it in the client, but without proper resolution we're not prepared to use NWS elsewhere
    As a workaround for problem 2. we removed schema validation, again not ideal
    Both SRs were escalated 9 days ago, but are still outstanding
    Incidentally our database is 11.2.0.1, but I've tested on 11.2.0.3 and both problems are still present
    We also wrap the NWS services using an OSB Proxy Service, and came across the same security issue that you describe (b) - to provide the credentials required for the NWS, simply create a Service Account (containing the credentials) inside OSB and attach it to the Business Service which invokes the NWS (http://docs.oracle.com/cd/E17904_01/doc.1111/e15867/service_accounts.htm)

  • Load balancing and clustering for SQL SERVER ANALYSIS SERVER instances to access large number of concurrent users for bi site

    HI
    how to do analysis server clustering 
    we have sharepoint bi site and we published many dashboards pointers ,filters kpis 
    and at a time some 200 to 300 concurrent users access these dashboards pages
    so for maintain this requirement how we apply clustering for ssas intances 
    and also it has load balancing 
    adil

    Hi Adil,
    According to your description, you want to implement SQL Server Analysis Services Clusster and Analysis Services Load Balancing, right?
    In SSAS, we can design highly available solutions in Analysis Services by using: network load balancing (NLB) technologies, failover clustering technologies, or both. For the details about implemention, please refer to the links below.

  • Does Traffic Manager provide database load balancing for MySQL?

    I need two VMs to implement MySQL Cluster in Windows Azure. VMs allow configure endpoint load balance set for Mysql, but I did not find tcp protocol in Traffic Manager. Does it provide this service for database
    load balancing?

    Hi,
    Traffic Manager works on the DNS level and routes traffic between public endpoints that sit behind a common DNS name. So you can't use this for your scenario.
    However, You can implement
    load balancing for VMs in another way.

  • Load balancing across database connection

    Do you provide load balancing across database connections and allow RDBMS load
    balancing for read only access?
    Thanks in advance.

    Hello, Christina.
    Load balancing with multiple machines is a little bit different than
    in the same machine. One of the important resource in this kind
    of application is network bandwidth, so tuxedo tries to keep the
    traffic among the machines as low as possible. So, it only
    balance the load (call services in other machine) in case all the
    services are busy in the machine where they are call.
    I mean, if you have workstation clients attached only to one
    machine, then tuxedo will call services in this machine untill
    all servers are busy.
    If you want load balancing, try to put one WSL in each machine,
    and the corresponding configuration in your WSC ( with the | to
    make tuxedo randomly choose one or the other) or spread your
    native clients among all the machines.
    And so, be carefull with the routing!

  • Distributed HA cluster with load-balancing and failover: advice?

    My workplace has a Xeon Xserve, which acts as our primary external server, with an attached ActiveStorage XRAID. We have just purchased a second Xserve/XRAID set to act as a mirror, which we will colocate. Both have Leopard Server installed, along with an array of additional software.
    What we want to do is have both servers load-balance between the two, with failover in case of a server or XRAID fault. I plan on using RSYNC to mirror static files between the two, and I'm looking into PostgreSQL replication and load-balancing solutions for our database. I gather that Apache supports web-server failover and load-balancing, as well. But, that still leaves the actual host and network setup to arrange.
    Does Leopard server support such a thing? The only information I found on IP failover instructs the user to place the two servers on the same subnet, directly connected via ethernet cable; obviously, this would not work in my case.
    Ideally, what we'd end up with is a situation in which the two systems kept each other in sync, both in static files and database data, and load-balanced between themselves; in cases of failure, the remaining system would transparently assume all duties until the other was restored, at which time they would resynchronize
    Any suggestions on how I could arrange such a thing?

    Interesting. Does this DNS-based approach support session tracking, though? I would need to have a user directed to just one of the two servers for the duration of their session, to avoid having to synchronize temporary files and such.
    You can't have it both ways. You need to build tolerance into the app.
    At the simplest level where you run all traffic to one site and use the second site as a failover/standby site you'll be OK most of the time - all users will go to the same server and their sessions will be intact.
    However, under any failover situation (your primary site is down for some reason), there is going to be some level of session traffic that it going to switch over to the other site. If your site depends on sessions then you're going to need to tolerate this kind of situation - your app will need to be able to fail gracefully if a user comes in with an invalid session cookie.
    Note, though, that this may be less of an issue than you at first think - all DNS clients will cache DNS data for whatever TTL you set. This means that if a user looks up your site name and you return an IP address with a 30 minute TTL, then that user is going to use the same IP address for the next 30 minutes and isn't going to ask the server again. This should negate most chance of a user suddenly switching from one server location to the other in mid-session.
    The trick comes in setting the DNS TTL low enough to effect a failover, yet not so long that you impact performance - e.g. you don't want the user to perform a DNS lookup on every page load. You may find that 10 minutes is appropriate. Just bear in mind that this affects how long a user could see your site 'down' before the failover DNS kicks in. Clearly you don't want to set the DNS TTL to a day since that may prevent the user switching to the secondary site for 24 hours by which time, hopefully, the primary site is back up, anyway.
    The 'right' TTL value may take some analysis on your traffic to see how long a typical user 'session' is. If the average user spends 20 minutes on your site, then it would make sense to set your TTL to somewhere around 20 minutes to give the best chance of their entire session staying on the same server.

  • A question about the SharePoint services load balancer

    Let's consider a farm with one WFE and two app servers, A and B. Both app servers are running the Managed Metadata Service (MMS). 
    User requests a page from the WFE, which talks to the database server. The operation needs information from the MMS, so the WFE requests information from the round robin load balancer for SharePoint web services. Let's say server A is down. 
    Here's my question - what happens next?
    a) The round robin load balancer tells the WFE the MMS is on servers A & B. The WFE tries server A, fails, and returns a failure. 
    b) The round robin returns servers A & B. The WFE tries server A, which fails. The WFE then tries server B.
    c) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE returns a failure. 
    d) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE queries the round robin service again.
    e) The round robin knows server A is down, returns only server B to the WFE.

    When a Service Application is down, the application load balancer removes that endpoint from the load balancer. When it becomes available again, it adds it back. This way the WFE would just contact the MMS endpoint that was available, not try and timeout
    against an unavailable endpoint.
