What are the pros and cons using ospf as the PE/CE protocol

pros and cons using ospf as the PE/CE Protocol

Hi,
Well in short,
pros:
well deployed protocol with good user experience
fast convergence
no redistribution required on ce side
cons;
type 1 & 2 routes (O) from one site are known as type 3 summary routes (OIA) in the other site
you need a sham link configured on the pe routers to get the routes as type1&2 at each remote site
If was deploying mpls vpn, i would use either ospf or bgp as pe/ce protocol.

  • What are the pros and cons using Active Data Guard vs Data Guard?

    My understanding is that Active Data Guard is an additional database option for Oracle 11gR2 Enterprise Edition. I need to know the pros and cons using Active Data Guard vs Data Guard in order to decide whether to get pay extra for the Active Data Guard.
    Thanks for any help.

    Before jumping in to Active Data Guard, one needs to evaluate :
    a. Is there really a need to run queries on the Standby ? The Standby could / should be at a remote site so queries are "across the network". Depending on the nature of the queries and the volume of output, the "performance" of the queries may not seem to be the same.
    b. If the database is not in Maximum Protection mode, the data "seen" at the standby may not be in "real-time" synch
    c. Not all applications are truely read-only when querying. Some applications use "jobs" that write to tables when querying. Such would not work with Active DataGuard. (example : EBusiness Suite). There are very complicated ways of handling this -- and one needs to consider if the complications can be introduced and supported.
    Over the network accessing standby read only is really not an good idea, I think no one will compare performance with primary and standby,
    But some of them they want to validate data which are very critical, as it is matching with primary or not, Its an added advantage with ACTIVE DATAGUARD
    Prior to that until unless stop MRP, open database and then we need to validate, So there is an interruption of recovery, I can say its also an advantage where there is no interruption of recovery.

  • Trying to way the pros and cons of upgrading to the octane

    3 lines, husband and son have ENV2's and I have an ENV3 with no problems at all with the shut down issue and have had it 2yrs.  We have no home phone and my phone is the main line so it's on 24/7 since I have an elderly Mom that lives in the area I have too.  I don't text a ton and I do receive some tweets and bettery life is very good.    We are due for upgrades and online at verizon it's saying we can all get the octane free.  Started reading all the user reviews and have some questions I need addressed if anyone can help.  For the most part I think the ENV2 and 3 are just about the same except I find the keyboard layout better on the 3.   I plan on looking at one in store and brining a list of stuff with me to check too.     Mary
    Low volume-  Know there was a big discussion on this and complaints galore.  On my ENV3 on the front at the top where I listen to calls is that also a speaker and that's why I can hear it good when closed and the octane does not work like this when closed?  I can make my own ringtones and amplify them same for hubby but this would be big cons for us if they didn't do something to correct it on newer phones coming out.
    Battery life seemed to be a complaint with some people.   I know if you text a ton and send photos that will eat up battery life so are some phones defective with the battery or are people maybe just sending a lot of photo message to eat up battery life I wonder.  With light texting and a few photos I can go a few days before I loose some bars now so hoping it would be the same on the octane.
    Back light stays on when powered down- user specific defect?
    To answer an incoming call, you must push OK first to unlock the device then press SEND to pick up the call. Should be a single button push to answer or at best OK twice, not 2 separate-  True or false or maybe they don’t have the settings for answering a call right?   Only have to push one button on my env3 and 2.
    slow frustrating interface glitchy software awkward front keypad- front keypad looks like my ENV3 with a contact button and an ok button to push and navigate music and photos and such does the ok button do that?  Maybe they have updated the software so it's not glitchty now?
     you have to open the flip to see missed calls and silence the alarm.  True or false?  See missed calls and alarm function on front of ENV3 when it goes off and this is important to me
    person on the other end of the line hears an echo. when i press "2" "12" is displayed-  User specific glitches?
    2.5mm headphone jack. you cannot play music without the micro sd card-  I load music on my micro card now so have one and putting music on the actual phone itself is not a concern for me and I have the head phone adapter to use my regular head phones.
    speaker isn't very loud while on speaker phone-  glitch with that users phone or all of them as I do use that function quite a bit.
    keyboard set up a little wonky- from photo looks like my ENV3 with space bar in the middle which I love better than the ENV2 keyboard
    dropping calls on regular basis- User specific to their area and service?  Hard to tell as they didn't state if all the other phones they have had never did that in their area.  I get no dropped calls at home or out an about with any verizon phones we have had, we get great service here, only exception might be if we are way out in the boonies which is rarely but for home and out and about in town I need good reception so would assume this phone would work the same on our service as the ENV2 and 3 do and our old flip phones did.
    there is no indicator that I have a voicemail message- guessing that has to be a user glitch as every phone we have had has a voice mail indicator so does it not have one?
    Case back is very hard to get off without bending the whole thing and I can see that once it’s a bit worn, it will probably be hard to keep on. I never dropped my ENV but have already dropped this twice due to a more slippery nature. Its also harder to open quickly- not sure if they bought a case other than the black rubberized one from verizon which I have for my ENV3 and is fine or they are talking about the phone itself?  Why would it be harder to open quickly?  Defective hinges on that one?
    for the camera. It doesn't have a zoom in option, which is strange- My ENV3 does not have a zoom function.  Don’t care as I have $2,000 worth of professional equipment to take good photos so just need to snap something once in a while out and about to maybe send to someone and my ENV3 in daylight is great for that so assume this is just as good if not a little better camera quality.

    We have 3 Octanes, I don't personally have one, I've not heard any complaints by any of them. My responses are in Bule below.

  • HT204053 What are the pros and cons of 1) choosing to use the SAME Apple ID for iCloud services on one side, and purchases on the iTunes Store, App Store, and iBookstore, on the other side; or 2) to have and use two separate Apple Ids for these "two sides

    All is in the title, so I repeat it below with a better identation.
    What are the pros and cons of
    1) choosing to use the SAME
                                                  Apple ID for iCloud services on one side, and
                                                  purchases on the iTunes Store, App Store, and iBookstore, on the other side; or
    2) to have and use two separate Apple Ids for these "two sides"?
    P.S.
    I have loads and loads of free podcasts in iTunes in my iMac, that are certainly more thant the 5 gigas the iCloud provides for free, so I don't want those to go to the cloud. But this is perhaps a different question...
    Also need to mention that I have itunes on a mac, a pc and an iphone.
    Sorry to look so silly with this question, but I don't get the "big picture".

    You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

  • What are the pros and cons re using an intel iMac vs MacPro with LP8?

    I'm considering getting a new intel Mac in the near future (presuming a new MacPro will be released in the near future - maybe at the same time as Leopard). I compose largely for film and television and I am composing largely using a combination of loops, software instruments and some recorded live performance. I usually sync to a low res quicktime movie.
    I do like the idea of a simple and uncluttered work environment with an iMac, added to which there's also a degree of portability with the iMac however the MacPro is obviously more powerful. I'm not sure how much the difference in power between the two computers would affect me.
    Would I be compromising myself much if I went for the iMac over the MacPro? What are the pros and cons of the iMac vs the MacPro in relation to Logic Pro 8?

    In the world large-scale music composition using samples, loops, etc (especially for film) your two biggest needs are RAM and HD speed/access. The imac looses big time in this department (as a single computer at least) as it can only be upgraded to 4gb ram, and only holds one internal HD, and also lacks any PCI expansion for DSP cards, audio interfaces, etc.
    In generalyou want to separate your data vs applications as much as possible, to ensure both can be accessed quickly and easily by the computer. So its best to have your system software / applications on one internal HD, and your logic data (samples, audio recordings, loops) on another drive(s). You can do this with an iMac via USB, FW800, & FW400, but depending on how big your projects get, how many USB and FW drives / interfaces you use, and how much data you need to stream, you could overload the buss on the imac (not sure if it has multiple busses or not). Plus speed wise, internal SATA are much faster than external drives, and the mac pro with its 4 internal slots seems like a great choice for speed and flexibility.
    However, if you dont find yourself doing large scale projects, then you might be better off going with an imac. We just purchased one for my father and it runs great! It blows the socks off of my Dual 2.5 G5 tower in terms of CPU speed! If you run into problems running things from the imac, you could always add a mac-mini down the road to stream sample libs, as a Logic node, etc, which seems to be a much more cost effective solution.
    I hope this was helpful, but I probably just made the decision harder . In fact, if I were to start over today, I dont know if I'd go with a MacPro, or an iMac / mac mini combination. they both seem to have their advantages / disadvantages.
    Best of luck!

  • What are the Pros and Cons of Using Batch Numbers over Serialization

    Dear SAP Gurus:
    Will someone please give me the benefits of using Batch Management over serial numbers in this case scenerio, or vice versa:
    Client wants to trace all the components of an assembly in a BOM.  Even the Raw material.  The client sends the material out today and has the vendor assign serial numbers to the individual pieces, the client gives the range of serial numbers to use.  We are looking at using batch numbers to accomplish this and issue one material and batch number to a production order.  Then use MB56 batch where used functionality to view history.  I am wanting to understand the benefits of this.  Please advise and points will be awarded as always. 
    Also, in this scenerio, can you issue multiple material/batch numbers to one vendor op that has its own production order?

    Yes it is a subcontract. 
    Example:  This is the solution but need the pros and cons of doing this scenerio
    Sheet of metal sent to vendor to make lets say 1800 peices of material number nas5703-01.  All 1800 pieces come back and issued to a production work order using one bacth number for one material item so that batch number can be traced in history in MB56 and a fit up report.

  • What are the pros and cons of installing java+abap stack for portal?

    Hi all,
      1.What are the pros and cons of installing java+abap stack for portal?
      2.what effect it does on the ume options to be choosen??
      3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
    regards
    Rajendra

    Hi Rajendra,
    The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
    https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
    In a nutshell:
    ABAP+JAVA
    Pros
    - Decrease # of servers required to administer the portal
    - Less costly
    Cons
    - Upgrades could be dependent on ABAP and Java release level
    - Additional load on the server due to ABAP stack
    - Limited scalability
    JAVA and ABAP on separate server
    Pros
    - Improved performance
    - Allows each system to be single-use purpose therefore downtime does not affect other components
    - More scalable
    Cons
    - Adds complexity to landscape
    - Additional costs

    Well, in most of the examples I've seen on the net people use "...extends JFrame"Well, I'm probably one of the bigest offenders (in this forum at least)
    google "composition vs inheritance", you'll most likely find some good reads Not know the difference between the two (I'm a problem solver, not a designer), I figured I should take up the challenge.
    So one of the first links I read said:
    Object composition and inheritance are two techniques for reusing functionality in object-oriented systems
    So I'm thinking how do you reuse a JFrame? Maybe if you build the frame with a menu bar or toolbar you could reuse some of the components but you don't reuse the entire frame. So it seems to me that the reuse aspect of inheritance or composition doesn't apply.
    Next link I read said:
    Make sure inheritance models the is-a relationship
    Now this makes sense to me. Lets say I'm creating a MineSweeper Game. Lets create a class with the following signature:
    public class MineSweeper extends JFrameThis obviously does not follow the is-a relationship rule. MineSweeper is-a Game, not a JFrame.
    So, I guess I'll have to update all my examples to use composition, so I don't mislead others on the forum.

  • What are the Pros and Cons while joining tables at DF and Universe level

    Hi Experts,
    I am new to Data federator designer. I need help on the below.
    Could you please let me know the Pros and Cons while joining the source tables in data federator
    And While joining the DF target tables in universe designer.
    Regards,
    Gana

    Hi,
    1. I have created target tables based on source tables with one to one mapping and then join all target tables in universe.
    Ex: Source tables: Infocube text tables, fact tables and 3rd party data base table
    Target tables:Target tables are same as source tables
    --- Yes this is the way to create target Tables  and join them in the universe.These target Tables gives you the flexibility  like in future your requirement is to add one more object based on some calculation which is not possible in the universe so that time you can create  one more column in the target table and do the calculation. at the same time if you are using source table you can not do anything.
    2. Created single target table with all objects of source tables and merged all sources tables data.
    Ex: Source tables: Infocube text tables, fact tables and 3rd party data base table
    Target table: Single table.
    --- This is bit complex structure to merge all tables data in the one target table.in this situation you have to put more efforts and it is more complex.basically this type of target table is useful when you are merging data by multiple source into single  or  creating one target table based on the  union of tables by adding two mapping rules or more and you can not join tables in universe.
    Better approach is first 1. create target tables based on the source tables and join them in the universe.
    Thanks,

  • Too worried to upgrade software. The pros and cons

    From a NOkia lover to others, 
    I am all for making improvements and fully understand that we can't always get it right first time every time but atm I am too concerned with the fact that updating my software will create problems that are non-existent in my eyes.
    My girlfriend updated her (my old) N70 software last week and now her phone is in the repair shop. This could just be a coincidence but....
    I had an N95 (on orange) and was stung when the "unlucky for some" version 13 was installed on the handset. See the epic thread here "N95 firmware upgrade affects battery life" (couldn't post link) 
    I carried out the full back up to my card as instructed but the games I purchased would no longer work so had to re-buy them. The battery life was killed in eight hours due to the wlan making a connection attempt as long as the battery would allow it to happen. The point is... all of this was not happening before the update. 
    It was that bad that in the end I was forced to upgrade / get a new contract before I was entitled to one from Orange and had to fork out for two contracts to get the handset spec I needed.
    I now have an N95 8GB and have no qualms with it what so ever. It has version 20 atm and pc suite informs me there is an update every time I boot the program up. So far.. I have declined to update.
    So what are the pros and cons and is it more of a risk to chance losing the licenses I have paid for and update if nothing is wrong?

    I myself am also worried. A friend of mine told me if there is no porblem with your current version of firmware for your phone then why update? It is not a assurance that after updating there would be no problems/bugs with the new version.My friend has a point. Why would we update if there is no problem with your current firmware version? Some would say it would be faster, there would be more improvements to the music ( which I know would be depending with your hardware and not the software).
    I am thinking of updating my firmware with a Nokia Service Center here in my country (Philippines). It is for free at the moment because my phone ins under 1 year Warranty. But I am thinking twice after what my friend told me.
    I hope my opinion helps you all out here.
