Advantages and disadvantages for Server/Router as a gatekeeper

Hi all....
What are the advantages and disadvantages for using a server(such as Sun Solaris server) or a Router(such as 3640) as a gatekeeper?
Thanks a lot.

HI ALL I have some problems with CiscoWorks SyslogAnalyzer and need help. I have configured syslog on my switches/routers and directing it to the ciscoworks server under solaris. Any thoughts?
I'm also looking to purchase a refurbished Sun Fire V880 or V480 Server, including some used Cisco Routers & Switches from our local Sun & Cisco Reseller, MCA Computer Corp. Does anyone have any experience with this company www.mcac.com?
thanks

  • What are advantage and disadvantage for Physical Standy and Logical Standby

    HI,
    What are advantage and disadvantage for Physical Standy and Logical Standby configuration?
    Thanks
    Ken

    Logical standby database
    The key advantage for logical standby databases is that they're opened read/write, even while they're in
    applied mode. That is, they can be used to generate reports and the like. It is indeed a fully functional
    database. Also, additional indexes, materialized views and so on can be created.
    However (this being a disadvantage) not all datatypes are supported.
    Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into
    SQL statements and replays them on the logical standby database.
    Physical standby database
    A physical standby database is a byte for byte exact copy of the primary database. This also means that
    rowids stay the same in a physical standby database environment.
    Oracle (or more exactly the log apply services) uses the primary database's redo log to recover the
    physical database.
    A physical standby database might be opened read only; however, the received logs are in this case not
    applied. When the logs are applied, the database is not accessible (it is then in a managed recovery state).

  • What are the advantages and disadvantages for the larger blocksize and for

    What are the advantages and disadvantages for the larger blocksize and for the smaller blocksize?

    Smaller blocksize
    Advantages
    GoodHas relatively large space overhead due to metadata
    (that is, block header).
    Not recommended for large rows. There might only
    be a few rows stored for each block, or worse, row
    chaining if a single row does not fit into a block, for small rows with lots of random
    access.
    Reduces block contention.
    Disadvantages
    Has relatively large space overhead due to metadata
    (that is, block header).
    Not recommended for large rows. There might only
    be a few rows stored for each block, or worse, row
    chaining if a single row does not fit into a block.
    Larger blocksize
    Advantages
    Has lower overhead, so there is more
    room to store data.
    Permits reading a number of rows into
    the buffer cache with a single I/O
    (depending on row size and block size).
    Good for sequential access or very large
    rows (such as LOB data).
    Disadvantages
    Wastes space in the buffer cache, if you are doing
    random access to small rows and have a large block
    size. For example, with an 8 KB block size and 50
    byte row size, you waste 7,950 bytes in the buffer
    cache when doing random access.
    Not good for index blocks used in an OLTP
    environment, because they increase block contention
    on the index leaf blocks.

  • Advantages and disadvantages for having the central purchasing organization

    Hi all,
    Cud neone list out the advantages and disadvantages of having central purchasing organization.
    and what is the best practice of selecting the puchasing organization.
    Thanks

    Hi
    <i><b>Cud neone list out the advantages and disadvantages of having central purchasing organization.</b></i>
    Rather than asking for the advantages and disadvantages it will be helpful if u see why the functionality of having the purchase organisation centrally and decentralised has been provided in SAP. I hope u have seen the help file in ur SAP about purchase organisation.
    The point u can note down which will be of importance is <b><i>Each purchasing organization has its own info records and conditions for pricing.</i></b> if u go for the centralised purchasing organisation say in company code u have three plants and purchasing organisation is for all theree plants, then the conditions and inforecords holds for all the thrre plants. If u go for the decentralised say for each plant different purchse organisation then each plant has its own inforecords and conditions. This is upto the business requirement which u should select.
    Similarly u can use this logic for the following cases
    Each purchasing organization has its own info records and conditions for pricing.
    Each purchasing organization has its own vendor master data.
    Each purchasing organization evaluates its own vendors using MM Vendor Evaluation.
    Authorizations for processing purchasing transactions can be assigned to each purchasing organization.
    All items of an external purchasing document, that is, request for quotation, purchase order, contract, or scheduling agreement, belong to a purchasing organization.
    The purchasing organization is the highest level of aggregation (after the organizational unit "client") for purchasing statistics.
    The purchasing organization serves as the selection criterion for lists of all purchasing documents.
    Here u can apply the logic and see how centralised and decentralise purchasing organisation effects. Whethe u want the data should be applicable for all plants then go for centralised if not go for decenralised.
    <i><b>what is the best practice of selecting the puchasing organization.</b></i>
    I think there is no best practice as such and it depends on how u r company business works.
    I welcome the comments from experts if there is any best practice.
    Thanks

  • I currently have a Macbook pro 10.6.8 and i'm interested software upgrade What are the advantages and disadvantages for upgrading my software.

    Ok... the only reason why i want to uprade my software is because of StarCraft 2. For those that don't know, Heart of the Swarm is coming out this March. I've been eagerly waiting for this expansion. I just read that SC2 HOTS will not be able to support any software below lion. I currently have 10.6.8 and i was wondering what are the disadvantages and advantages (aside from being able to play this expansion) of upgrading my software? Are there any draw backs, etc.

    Go all the way to Mountain Lion if you can...
    Upgrade to Mountain Lion
    But...
    Before attempting any Major Upgrade... get yourself an External Hard Drive... and create a Bootable Clone Backup of your current Hard Drive...
    By far the easiest way to make such a Backup, is to use something like
    SuperDuper  http://www.shirt-pocket.com/
    or CCC  http://www.bombich.com/
    That way, should anything untoward happen during the Upgrade,
    you will NOT LOSE ANYTHING.
    (Get an EHD that is at least equal to your current Drive...)
    Also, get more RAM...
    You can use this Link to check which RAM is suitable for your Mac...
    http://eshop.macsales.com/shop/apple/memory/
    It is Important to get the Correct and Matching RAM
    For best performance, fill all memory slots, installing an equal memory module in each slot.
    That site also has videos on how to Install RAM should you need it...
    Here are Apples Instructions... Installing RAM

  • Singl/Multiple Server Oracle 10g DB and AS- Advantages and DisAdvantages

    Hi Friends,
    I am using Application1 using Oracle 10g Application Server and Oracle 10g database.
    Now i planned to use Application2 using Oracle 10g AS and Oracle 10g DB
    I need to know what will be the Advantages and Disadvantages if i have the schema for Application2 in the existing Oracle 10g DB / having it in another Oracle 10g DB Server
    sameway what will be the advantages and disadvantages if i have the Application2 regsiterd in existing Oracle 10g AS(Multiple OC4J Instance) / having it in another Oracle 10g AS Server.
    Regards

    To start the list, for me some of the advantages are:
    Same DB:
    - less overhead and wasted CPU Cycles (therefore potentially lower license fees)
    - easier maintenance (backup, recovery)
    - easier tuning (fewer conflicting external environments asking for same resources)
    - Oracle is designed for this, allows use of Resource Manager
    - technically RAC is a clustered 'same DB'
    Same AS:
    - less overhead and wasted CPU Cycles (therefore potentially lower license fees)
    - easier maintenance (backup, recovery)
    - easier tuning (fewer conflicting external environments asking for same resources)
    - Oracle is designed for this, use AS clustering
    Different DB:
    - separate maintenance (patch, upgrade) cycles for different SLA
    - easier tuning (isolate tuning to one app)
    - easier security (most developers have no idea about Oracle security and make merge impossible)
    Different AS:
    - separate maintenance (patch, upgrade) cycles for different SLA

    Hi Nitin,
    A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object. What is stored in the database is a SELECT statement. The result set of the SELECT statement forms
    the virtual table returned by the view. A user can use this virtual table by referencing the view name in Transact-SQL statements the same way a table is referenced.
    For more information about the advantages and disadvantages of views in SQL Server, please refer to the following two articles:

  • Advantages and Disadvantages of Soap

    Advantages and Disadvantages of Soap
    Hi Firends,
                  Could you please tell me the Advantages and Disadvantages of using Soap adapter, i need them urgently.
    Note: High reward points will be given for each answer

    Hello
    SOAP is an XML-based protocol for exchanging information in a decentralized, distributed environment. It was made for Web, a combination of XML and HTTP opens up new options for distributed data exchange and interaction in a loosely coupled web environment. SOAP is a technology that allows XML to move easily over the Web. SOAP does this trough an XML envelope for delivering XML content and specifying a set of rules for services to follow when they receive a SOAP message.
    The fundamental change brought about by SOAP has been the ability to move data anywhere across the Web. Before SOAP there were only two main options for moving data between partners.
    One was to build a wide area network spanning a broad geographic region and let the partners plug into it. This was the approach taken by EDI, which defined messages and protocols for data transfer but left the network details up to the partners. The result was a collection of networks that pretty much locked the partners in and made it difficult and expensive to reach out to other EDI networks and costly to bring in new partners.
    The second approach for moving data between partners was to build a distributed object infrastructure than ran over the internet. This was the approach taken by Common Object Request Broker (CORBA), Remote Method Invocation (RMI) and Distributed Component Object Model (DCOM). The problem was that each had to decide on a protocol that could sit on top of TCP/IP and handle inter object communication. CORBA Chose Internet Inter-ORB Protocol (IIOP), DCOM chose object Remote Procedure Call (ORPC), and RMI chose Remote Method Protocol (JRMP). While this approach reduced the need to share the same underlying network, the drawback was that CORBA could talk to CORBA, RMI to RMI and DCOM to DCOM, but they neither could talk to each other nor directly to the web except through special sockets that required adding extra layers to an already complex architecture.
    SOAP the third option, combines the data capabilities of XML with the transport capabilities of HTTP, there by overcoming drawbacks of both EDI and tightly coupled distributed object system such as CORBA, RMI and DCOM. It does this by breaking dependence between data and transport and in doing so opens up a new era of loosely coupled distributed data exchange.
    SOAP Carries an XML RPC tradition by defining an XML language for packaging arbitrarily XML inside an XML envelope. Although SOAP does not depend on HTTP, the momentum behind SOAP is attributable to the fact that HTTP will usually be used for transfer protocol for SOAP messages.
    SOAP is a transport protocol similar to IIOP for CORBA, ORPC for DCOM or JRMP for RMI.
    SOAP differs from CORBA, RMI or DCOM in several ways.
    IIOP, ORPC and JRMP are binary protocols, while SOAP is a text based protocol that uses XML. Using XML for data encoding makes SOAP easier to read than a binary stream.
    1) Because SOAP is text based, it is able to move more easily across the firewalls than IIOP, ORPC or JRMP.
    <p2) SOAP is based on XML, which is standard driven rather than vendor driven. Potential adaptors are less likely to fear vendor lock in with SOAP. </p2>
    The net effect is that SOAP can be picked up by different transport protocol and delivered in different ways. For example, when used with HTTP it can be delivered to a web server, when used over FTP it can be deposited directly into a file system and when used with SMTP it can be delivered to a user's mailbox.
    Many companies exchange data between established partners is proving totally satisfactory way to leverage the benefits of XML and the web. In this scenario the required are an agreed upon schema either DTD or an XML schema, for XML data being exchanged and the SOAP server capable of handling the incoming XML as it arrives over the web. Details about what kind of schemau2019s to expect and who will check the XML conforms to the schema are decided offline by individuals participating in the process. On the software side senderu2019s needs to be involved in packaging their data in an XML document. For those companies already storing data in XML, this should require only minimal effort. If the stored XML data is not in the form required by the agreement, an XSL Transformation(XSLT) style sheet can be programmed to automate the transformation.
    SOAP messages define one way data transmission from sender to the receiver. However SOAP messages are often combined to implement patterns such as request-response. When using HTTP binding with SOAP, SOAP messages can use the same connection as the inbound request.

    hi,
    Data about an application object is often distributed on several tables. By defining a view, you can define an application-dependent view that combines this data. The structure of such a view is defined by specifying the tables and fields used in the view. Fields that are not required can be hidden, thereby minimizing interfaces. A view can be used in ABAP programs for data selection.
    More complicated views can comprise several base tables, the individual tables being linked with a relational join operation. If we dont specify the key fields, it takes time to fetch teh results.

  • Advantages and Disadvantages of JMS Queue over Fabric

    HI,
    I want to know both the advantages and disadvantages of using JMS queue over the default Fabric queue in B2B adapter.
    Is it ok if I configure all my inbound and outbound transactions across all the trading partners to communicate with their respective SOA composite via the default JMS Queues(B2B_IN_QUEUE and B2B_OUT_QUEUE)?
    Please advise.
    Thanks in advance.
    Regards,
    Monica

    Hi Monica,
    But the size of the payload which I am using is unpredictable, it can differ from 1 MB to 40MB in future.This is not a problem. B2B can handle MB's of file if server has enough resources.
    all other payloads greater than 3MB, it is getting faulted with the message:
    "SAX Exception in translator. SAX Exception raised while trying to SAX Parse InputStream . Please make sure that the xml data is valid."Please remember that when B2B will find a large payload then it will write the large payload into the "Large Payload Directory" (defined in Administration--> Configuration) and pass it's reference to the middleware. So at middleware, you will not receive the actual payload but you will receive it's reference. Using File adapter sync read option, you may read the large file from "Large Payload Directory" at SOA layer.
    If you are using PS5 (11.1.1.6) then you will see that for large payload, B2B passes the JMS header LARGE_PAYLOAD to the back-end so in your composite, you may build logic around this. If this header (LARGE_PAYLOAD) is not coming at SOA layer then payload will be available in the body and if it is populated then payload will be available in the "Large Payload Directory" and it's reference will be available in the message body.
