Need best practice advice on RAC 2 nodes configuration/setup

I need to implement 2 RAC nodes with linux redhat 5.
Right now I did ifconfig, and it shows:
ifconfig | grep "^[eb]"
eth0 Link encap:Ethernet HWaddr 18:03:73:EE:7E:7F
eth0:1 Link encap:Ethernet HWaddr 18:03:73:EE:7E:7F
eth0:2 Link encap:Ethernet HWaddr 18:03:73:EE:7E:7F
eth3 Link encap:Ethernet HWaddr 18:03:73:EE:7E:81
eth3:1 Link encap:Ethernet HWaddr 18:03:73:EE:7E:81
eth4 Link encap:Ethernet HWaddr 18:03:73:EE:7E:83
eth5 Link encap:Ethernet HWaddr 18:03:73:EE:7E:85
I did not see any bond0 or bond 1.
I think oracle recommend privet interconnect to be bonded. We use CTP-BO , so I want to know should I request to bond the interface plus service?
What is the command to test that the interface are setup right?
Thank you for all the response in advance.

Which version are you setting up and what are the requirements? IF you are discussing the use of NIC bonding for high availability beginning in 11.2.0.2 there is a concept of "High Availability IP" of HAIP as discussed in the pre-installation chapters,
http://docs.oracle.com/cd/E11882_01/install.112/e22489/prelinux.htm, section 2.7.1 Network Hardware Requirements.
In essence, using HAIP eliminates the need to use NIC bonding to provide for redundancy.

  • Nodes in RAC One Node configuration

    Dear all,

    Thanks Rafi and Sorry for not making it clear.
    The whole configuration will be rac one node (With 4 nodes) with out dataguard implementation.
    If the primary site goes down(s1,2 and storage) , can the secondary site wil be up automatically (s3,4 and storage). Please note storage is with ASM (normal redundancy ) primary storage at Head office and Secondary ASM storage at DR

  • SubFlow best practice advice please

    I am new to IPCCX scripting and would like some advice on whether multiple SubFlows are a good idea.
    We have 16 small Call Centers that all have very basic scripts. I plan on adding a Holiday/Emergency Closure SubFlow to all of them and I would like to add a few additional features as well.
    I plan on adding:
    ·         Position in Queue
    ·         Expected Wait Time
    ·         If more than X number of callers in queue, inform the caller that they cannot be helped at this time and to call back later.
    ·         If Expected Wait Time exceeds closing time, inform the caller that they cannot be helped at this time and to call back later.
    (I know the last two sound pretty harsh, but it’s government, and there is no budget to hire more operators. I think it is better to let the callers know early that they need to call back, than to have them wait for two hours just to be disconnected. And no, this is NOT the 911 call center!!!   LOL)
    My questions are:
    Would it be ok to add each feature as a SubFlow? Or could there possibly be performance or other issues by having so many SubFlows in one script.
    My other option is to add each item internal to each script, but that would be a lot to tackle 16 times…
    Lastly, is there a best practice on how short a script should be for performance? I know you can’t have one that is longer than 1000 steps, but should I try to keep the step count below a certain number?
    Any advice or insights would be greatly appreciated…
    Thanks,
    Doug.

    Doug,
    Most of the items your list are included natively in UCCX.  Use the Get Reporting Statistic step to obtain the expected wait time, position in queue, and total queue time information. The current time-of-day can be had using a Time variable.  You'll need to do some work to convert the values into something you can play to the calling party as a prompt, a subflow is great for that, but you shouldn't need to reinvent the wheel.
    Take the time to draw out the call flow for each of the 16 contact centers on paper or in MS Visio. If your 16 call flows are very similar in the way they operate, consider a master script that just changes the prompts/menus based on the number dialed.  Leverage XML or a database (if you have premium licensing) to pull in the relevant information you need for each DNIS.  You may find you can streamline the entire system, or at least a good portion of it, without it becoming 16 unwieldy applications.

  • Expert opinion needed: Best practices to handle huge rowsets on UI

    Hi All,
    I need to know what are the best practices from Oracle to handle huge rowsets on the UI.
    My ADF 11g app is a custom monitoring cum reporting tool for a highly active integration solution.
    The user can give me a selection criteria say show transactions between yesterday and tomorrow and our highly active transactional system may return upto 5000 records.
    I am showing these records in a tabular format and since pagination is not there we are depending on auto scrolling which is kind of slow.
    So please advice me what options come to your minds for showing/informing users of such rowsets.
    I am aware ideally UI should not have more that a couple hundred records but our use case does not adhere to that.
    Thanks

    since pagination is not there I'm not sure what you mean by this, the ADF Faces table does pagination when you scroll - so if your business service has 5000 records but the rows property of your table is set to 25 - you'll just fetch 25 records to the client.
    When you scroll down you'll fetch another 25.
    This type of thing is automated for ADF BC data controls - and you can control the range set.
    We also generate the code needed for EJB Facades to do this with JPAs.
    If you have your own Java class as a data source you'll need to implement this pagination on the business service side see exapmle 37 here: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html

  • Best Practice Advice - Using ARD for Inventorying System Resources Info

    Hello All,
    I hope this is the place I can post a question like this. If not please direct me if there is another location for a topic of this nature.
    We are in the process of utilizing ARD reporting for all the Macs in our district (3500 +/- a few here and there). I am looking for advice and would like some best practices ideas for a project like this. ANY and ALL advice is welcome. Scheduling reports, utilizing a task server as opposed to the Admin workstation, etc. I figured I could always learn from those with experience rather than trying to reinvent the wheel. Thanks for your time.

    hey, i am also intrested in any tips. we are gearing up to use ARD for all of our macs current and future.
    i am having a hard time with entering the user/pass for each machine, is there and eaiser way to do so? we dont have nearly as many macs running as you do but its still a pain to do each one over and over. any hints? or am i doing it wrong?

  • Need best practice when accessing an ucm content after being transferred.

    Hi All,
    I have a business requirement where I need to auto-transfer the content to another UCM when this content expires in the source UCM.
    This content needs to be deleted after it spends a certain duration in the target UCM.
    Can anybody advise me the best practice to do this in the Oracle UCM?
    I have set up an expiration date and trying to auto Replicate the content to the target UCM once the content reaches the expiration date.
    I am not aware of the best practice to access the content when it is in the target UCM?
    Any help in this case would be greatly appreciated.

    SR,
    Unfortunately temp tables are the way to go. In Apex we call them collections (not the same as PL/SQL collections) and there's an API for working with them. In other words, the majority of the leg work has already been done for you. You don't have to create the tables or worry about tying data to different sessions. Start you learning here:

  • Captivate 4.0 - Need best practice tips on panning, templates, resolution, etc.

    Hi all,
    Been searching all over in case someone has already published Best Practices for Captivate 4.0 (particularly the new/enhanced features), but coming up empty. My client's in house graphics person has been tasked with creating a template for us to use for a number of software simulations. He's running in to these challenges:
    - Our SWF needs to be 800 x 600 and he created the template for this size, but the app won't fit.
    - He's found the panning feature to produce very choppy, disappointing results. Tips?
    - His suggestion is we capture at 1024 x 768, then resize to 800 x 600, then copy/paste the slides into his 800 x 600 template. Would we be better off recreating the template at 1024 x 768 and not resizing until the final output is generated for each tutorial? His concern is that our template will then become larger, making it harder for us to send back and forth as changes are made, etc.
    Any other suggestions for how to deal with the resolution issue, how best to take advantage of templates, etc.?
    Thanks,

    Hi there
    In my own opinion, Panning is a nice attempt, but just doesn't cut the mustard. It's nowhere near as good as the panning one sees with Camtasia Studio.
    I might suggest combining Camtasia with Captivate for the ultimate development set. There are aspects Captivate shines in when compared with Camtasia, and there are aspects Camtasia shines in when compared with Captivate. So I say if you can afford it, go for it!
    Now I know that both packages are sort of pricey and not everyone can afford both. In that case you might want to try Jing, which is free to use. I've not looked very deeply at it, but it may offer some of what Camtasia does. You could then use that for your panning and enhance Captivate that way.
    Cheers... Rick

  • Rules Best Practice Advice Required

    I find that I'm fighting with the Business Rules in my BPM project, so I'd thought I throw the scenario out here and see what best practices anyone might propose.
    The Example*:
    Assume I have people, and each of them is assigned a list/array of "aspects" from an enumerated set: TALL; SPORTY; TALKATIVE; TRAVELER; STUDIOUS; GREGARIOUS; CLAUSTROPHOBIC.
    Also assume I have several Marketing campaigns, and as part of one or more processes, I need to occasionally determine whether a person fits the criteria for a particular campaign, which is based on the presence of a one or more aspects. The definitions of the campaigns may change, so the thought is to define them as business rules; if they change, the rule changes, without impacting the processes themselves (assume the set of campaigns doesn't change, just the rules for matching aspects to a particular campaign).
    My initial take is to to define each campaign as a bucketset, containing aspects, the presence of which indicates inclusion in the campaign. If a person has ANY of the aspects, they are considered a member.
    Campaigns (each perhaps defined as a LOV bucketset):
    DEODORANT: SPORTY, TRAVELER, GREGARIOUS
    E_READER:STUDIOUS,TRAVELER
    BREATH_MINT:TALKATIVE, GREGARIOUS
    HELMET:TALL, CLAUSTROPHOBIC
    So we want to create a service to check: Does a person belong to the BREATH_MINT campaign? We extract their aspects and check to see if ANY of them are in the BREATH_MINT campaign. If so, we return true. Basically: return ( intersection( BREATH_MINT.elements(), person.aspects() ) ).size() > 0
    The problem is: what's the best way to implement this using Business Rules? Functions? Decision Functions? Decision Tables? Stright IF/THEN? Some combination of the above? I find I'm fighting the tool, which means that, although this is a fairly simple problem, I don't understand the purpose of the various parts of the tool well.
    Things to consider:
    Purpose: test a person for inclusion in a specific campaign
    Input - the person's aspects, either directly, or extracted from the person
    Output - a boolean
    There can be a separate service for each campaign, or it could be specifed by an enumerated value as a parameter.
    Many thanks in advance!

  • Swtich with 2 wireless routers (configuration for best practice/advice?)

    HI folks,
    I have a gigabit switch, and 2 wireless G routers.  I'll leave the model numbers out as it's fairly irrelevant - all linksys.
    Router 1 is used as a router only (due to location in basement)
    Router 2 is used for wireless only
    My current network setup:
    DSL MODEM (accessed on 192.168.2.1 - can not be changed) > Router 1(192.168.1.1)
    Router 1 > Switch (i believe it can't be changed 192.168.2.12 - no webgui)
    Switch > everything else including Router 2
    Everything works except Router 2 - can't connect to it wired or wirelessly until connected directly to a pc.
    Is my setup wrong
    and/or is there a best practice?
    Many thanks!!!

    What is the model number of the switch?
    Normally a switch that cannot be changed does not have an IP address.  So if your switch has an address (you said it was 192.168.2.12)  I would assume that it can be changed and that it must support either a gui or have some way to set or reset the switch.
    Since Router1 is using the 192.168.1.x  subnet , then the switch would need to have a 192.168.1.x  address (assuming that it even has an IP address), otherwise Router1 will not be able to access the switch.
    I would suggest that initially, you setup your two routers without the switch, and make sure they are working properly, then add the switch.  Normally you should not need to change any settings in your routers when you add the switch.
    To setup your two routers, see my post at this URL:

  • Best practice for deletion of SAP standard configuration

    Does anyone have any documentation related to deletion of standard SAP configuration?  My client is requesting deletion of all the standard delivered company codes and I believe it is best practice to never delete them.  I am looking for supporting documentation that supports this.

    Rhonda,
    I have never seen a system where the standard delivered company codes did not exist, so I can't say what the implications of deletion are.  I suppose it is possible to do....
    For documentation,  I guess you could search through service.sap.com/support. 
    I would think you would respond to the request as follows:
    Tell the client it will be extra work to delete the items.  Which will translate into additional billable fees.
    Tell the client (in writing) that you cannot predict what all possible outcomes will be, but that you are willing to work with him to fix anything that gets broken in the process.  For additional billable fees.
    In the end, the client is paying for your advice and your services.  In the end, he owns the license and the system upon which it is running.    He can have anything he wants, there is no other 'right' or 'wrong'.
    I suggest you don't delete anything in client 000.  Most companies keep this as a reference.  If the client later decides to reconstruct, this would be a nice source of info.
    Since company codes greatly affect FI/CO, you might want to post the question in one of those forums.
    Best Regards,
