Differences between Data Pump and always by inheritance, import and export

Hi all

I work as a junior in my organization dba and I saw that my organization still uses legacy import and export utility instead of Oracle Data Pump.

I want to convence my manager to change the existing deal with Oracle Data Pump, I have a meeting with them to keep my points and convence them for Oracle utility pump data.

I have a week very convencing power but I won't miss to discover myself, I can't work myself and really a need with differences of strength against import and export, it would be really appreciated if someone can put strong points against Oracle Data pump on legacy import and export.

Thank you

Hello

a other people have already said the main advantage of datapump is performance - it is not just a little more fast exp/imp it is massively faster (especially when combined with parallel).

It is also more flexible (once much more) - it will even create users with exports level schema which imp can't do for you (and it is very annoying that he could never).

It is reusable

It has an api plsql

It supports all types of objects and new features (exp is not - and that alone is probably reason to spend)

There even a 'legacy' at 11.2 mode where most of your old exp parameter file will still work with him - just change exp expdp and impdp print.

The main obstacle to the transition to datapump seems to be all "what do you mean I have to create a directory so that it works", well who and where is my dumpfile why can't it be on my local machine. These are minor things to go well beyond.

I suggest do you some sort of demo with real data of one of your large databases - do a full exp and a full expdp with parallel and show them the runtimes for them to compare...

See you soon,.

  • What is the difference between the IO and line?

    Hi all

    I'm using Labview 7 and in my mahcine I have an installed 6013 card. However, there was an interface card designed by someone else long ago, on the table, only AO0, AO1,..., A07, DIO0, DIO1,..., DIO7 were printed. In the program, I saw some code to write to digital Line.vi allows you to send data to the digial io. Say that I write for DIO 3, so I understand here DIO 3 means the channel of e/s 3, but online? What is the difference between the channel and the line? When I write the data to a single channel of e/s, are us wriitng a byte or a bit of it? Thank you.

    A channel is usually used with inputs/outputs analog.  Each AI or AO is a string.

  • Difference between "Auto off" and "Sleep" on LaserJet P1102W

    The user guide for the LaserJet P1102W indicates that the default Auto setting in the properties is 5 minutes.  "Automatic stop" drop-down list does not contain a setting of 5 minutes - rather it contains "never, 30 min and 1,2,4,8, & 24 hours."  However, the drop-down list 'Sleep' contain 5 min and other selections up to 1 hour.  What is the difference between auto-off"and"Sleep ".

    After the installation of this new printer, the default settings have been = 5 Minutes ' Sleep' and 'Auto off' = never

    I have several computers around the House than any print to the same printer.  I want to always available for printing without issue in the basement to activate it, but yet they want more economic mode.

    What is the difference between 'Sleep' and 'Auto off' and how should I put them in my terms of service desired?

    Thank you.

    Hello

    I understand that you are looking for some explanations between the Sleep and automatic shutdown of the Laserjet P1102W printer. I would be happy to offer you answers!

    For your desired operating conditions, I think that you already put as you would like. Standby essentially puts the printer in a State of very low power consumption, but the printer can be awakened from this State by sending a print job (meaning you don't have to go to the printer to remove it from that State). The auto-off function off the printer completely after a period of time. The only way to take the printer out of State would be to go to the printer and press the power button.

    To have several computers connected to this one printer I would recommend leaving the auto-off Never and Eve to what you think is the best. As I said, the printer will wake up fashion 'sleep' and accomplish what you ask without physically going to the printer.

    Hope this helps, have a nice day!

  • What is the difference between Foglight JavaEE and Foglight JMX monitoring?

    Hello

    I have a plan to monitor the 6.1.0.17 WebSphere Application Server (32 bit) and 7.0.0.5 (64-bit)

    But I understand not all Foglight for JavaEE and Foglight for JMX.

    Foglight for JavaEE or Foglight for JMX is able to monitor WebSphere?

    What is the difference between Foglight JavaEE and Foglight JMX monitoring?

    Thanks in advance

    Jeans

    Just to add to the excellent answers already posted.

    We have 2 agents which allows you to monitor Java:

    1. a JavaEE agent that runs inside the JAVA virtual machine and the information of both JMX and instrumentation.

    This Agent will give you JMX information like information of JVM (use of the bunch, son etc.), of the Application and server availability information and other information of JMX/PMI (connections pools, pools of ejb, servlets, jsp, JCA and more).

    Java EE & # 039agent also gives you information of the instrumentation - RFA count and response time, exceptional output and timeout information, distribution of queries (App/DB, component technology, server, application failure), object tracking, transaction flow and stransactional between servers and data sources) and ask traces (the ability to see the trees of the RFA at the method level to know where things are slow/stuck).

    2 JMX agent is running outside the JVM but can run on the same computer or on a remote computer, this agent requires access active, JMX. This agent gives you information JVM, availability server/applications, as well as some data as the application server published using JMX (pools of connections, JCA, EJB, servlets, etc.). The JMX agent also gives you the ability to see a list of the mbeans, get the data they expose (javaEE agent gets only a predefined list (same list that is used as a template for the application servers in the JMX agent)).

    Hope this helps

  • What is the difference between the stop and restart?

    What is the difference between the stop and restart?  I feel that stopping closed all processes, completely erases RAM memory and clears the cache of the processor.  I need to know if 1) this is a correct assumption and 2) which is better for daily maintenance of the system.  Thank you in advance.

    Hello Jeremy_1976,

    Your support when the judgment is correct. Basically, it stops the process and completely turns off your computer. Reboot, however, temporarily your PC stops, then turn it on again. This happens usually when Windows updates are installed. After installation, the system is restarted (rebooted) so that any update has been successfully installed and works as it should. You can be a little mixed upward the reboot and the hibernation. Reboot is, as I have indicated previously, basically a reboot of your machine. Ultimately, your PC is on again after a reboot. However, hibernation, stores all data currently in memory in a special file, then the PC turns off. When you then turn on your PC, that is, coming out of hibernation, hibernation files is used to restore the status of the PC than when you initially put into hibernation. In other words all the programs you had open before will automatically open and be ready to use hibernation.

    Hibernation or sleep for that matter is for short-term use. It is normal in Hibernate, or sleep if you want to be away from your PC for half an hour or so. If you leave more than I suggest you stop completely.

    A point to remember about hibernation is that, if you use put into hibernation, you can't, once you get out after hibernation, install programs or updates. You have to stop and restart normally to do.

  • Difference between "Home network" and "Business Network" WITHOUT a domain name in Windows 7?

    I'm paranoid and always try to choose security options more high.  In preparation for the implementation of a small Windows 7 network behind a NAT router wireless and wired, I'm working through "Microsoft Windows 7 in depth" by Cowart and Knittel (what, rights of copyright 2010).  I fell right on the following steps (mentioned verbatim in p. 446-447), that I don't understand.  (The steps are clear enough but the real difference between the first two choices is not.) :

    «.. . Click on change settings, click Network ID...  You are prompted to select the option that best describes your computer:

    • This computer belongs to a network of business; I use it to connect to other computers at work.
    • This computer is a computer at home; It is not part of a corporate network.

    «That one you choose made a significant difference...»  If you choose the option "Business Network", Windows configures your computer for a better level of security it will be for domestic use [my underlining].  The wizard then asks you choose one of the following responses:

    • My company uses a network with a domain name
    • My company uses a network without a domain name

    «.. . If you build your own network as described in this chapter, select a field, then click Next.  The last question asks a name for the network working group.  Leaving the WORKING group by default in place".

    It seems that you can set up a "Business Network" 'without a domain' that outward behaves as a similar "home network".  If Yes, what is this 'higher standard of security' that will result? -JCW2

    There is only one difference between home network and profiles work that appears when you sign in for the 1st time.

    A profile of home network allows to create or join a homegroup, on a job profile that you can not. So what it means actually using the term "business" is false and the differences in security are limited.

    One of the limitations of a workgroup can access one action requires the credentials of all users to set up on the host pc, setting up a homegroup automatically creates a common user between computers that could be considered a low security setting...

  • What is the difference between Unicast RPF and Reverse Path Forwarding?

    I am confused between Unicast RPF and Reverse Path Forwarding function.

    What is the difference between Unicast RPF and Reverse Path Forwarding?

    Because they have all two please check the address of the source of each package before sending it to the destination too?

    Reverse Path Forwarding is used only when the network want to build a tree shared multicast communication and then we must use Unicast RPF after creation of the shared tree?

    The mechanism of the RPF is mainly used to ensure no loop of routing traffic.

    As you probably already read, it does by ensuring that his route to the source address of a packet received is accessible via the same interface that the packet is entered in the. Think of the notion of "root port" in STP. all root ports are similar to the root, sunflower follow the Sun. Therefore, it is naturally a loop prevention mechanism.

    With multicast traffic, it is quite likely to create multiple loops of routing the nature of 'destination' traffic. For this reason, using a mechanism as the RPF to ensure you are on the "road to the root" (to say) to the source originating multicast traffic. Otherwise if you're not then you either receive this traffic route in a loop, or a suboptimal path.

    uRPF works essentially the same way, except that it is done for unicast traffic instead. Now with unicast traffic your flow is from a source and directs to a single destination. Given that, as the fact that you are using a dynamic routing algorithm (which allows to select the path to a destination), you can have loops of your network for unicast traffic flow routing; of course there may be exceptions to pitfalls of configuration route redistribution.

    However RPF when it is applied to traffic unicast can add another advantage, and it's verification IP source. That's why we can use it as a security mechanism to ensure that data are from where it is supposed to come.

    On the limit of the L2, you then have mechanisms such as guard source IP to ensure that the correct host is not usurpation of their IP address.

    By analogy RPF can be used for checking at source for multicast traffic, and it is intrinsically that however, the most important role is so that it can be used to guarantee without loop routing of multicast traffic.

    I hope that helped clear things upwards and not confused you any more with all this.

  • difference between control flow and check knowledge module

    Hello

    I know ckm and flow control. What is the main difference between the Frother and CKM?

    CKM is the model of knowledge that ODI will use to check all the constraints you create.

    Flow control is the way to a check constraint during the flow of an interface (it's way happens to you in your integration tables [temporary]). This method deletes the data of 'bad' and it will record in a table of $ E. Also, you have some option to recycle errors (next ODI run will try to reuse these data)

    Static control is another way to check your constraints. This is static as its name suggests and is average, it will only count the errors, but it won't do anything with the data. It might happens in the source tables.

    The most used method is the regulator of throughput with certainty, but static electricity has some advantages too.

    For example, flow control has only a little when you check duplicate data. When he found it eliminated the two registry (or more if there are more). It's average, you get nothing in the end.

    You can use the static control to check your sorce tables and create a process to eliminate or filter duplicate data, allowing only data duplicated to cross.

    Hope this can help you.

  • difference between the view and the procedure

    Hi Master,

    Today I received a request from my senior technical leader... !!

    Q > what is the difference between the view and the procedure?

    I got response like this...

    A view represents the logic of one or more tables/views. It won't take no place in db... It is a virtual table, query will only store in db... useful

    for safety... If the main table has obtained changes... automatically discovers also change... etc.

    Proecudure is a db object will be performs a perticular action... It may or may not return values. ?

    How a view and procedure may do the same thing?  They are two different things with different objectives.  You use the correct one depending on what you want to achieve; they are not interchangeable.

    And another question...!

    (Q) how you will store Japan, characters of China in a database table? will there be a new feature in Oracle 11 g?

    (A) I use dbms_lob package? Japan/China characters are multi byte characters... so we can use the nclob data type?

    is this correct... ?

    No, it not there no novelty in Oracle 11 g for the storage of Japanese or Chinese characters, because there is already a feature for their storage in previous versions as well.  It is determined by the parameters characterset and nationality that you use when you create the database.

    Why would you choose to store them in a LOB using DBMS_LOB?  Yes, they have multibyte characters, but if you have configured your database for the correct character sets, for example using UTF - 8, then you can store the characters in VARCHAR2, like any other language.  The only difference is that the storage of 4000 bytes limit still applies, so you maybe isn't able to store 4000 multibyte characters in a varchar2 column 4000 single-byte, it can be as little as 1000 characters if they are all characters in 4 bytes.  (Note: 12 c limit in SQL can be increased up to 32,767 characters, to harmonize it with variable varchar2 PL)

  • Difference between Adobe Reader and Adobe Acrobat Reader DC, please?

    I always check manually (and daily) for updates. A few weeks back, I checked for updates of Adobe Reader 11 and found nothing, but found only adobe Acrobat Reader DC listed. I assumed it was the newest Adobe Reader 11 and downloaded and installed Acrobat Reader DC replacement. No problem, very well.

    Moving fast until today when I checked the updates to the Acrobat Reader DC, and I found an update for Adobe Reader 11 (Version 11.0.11). So, what is the difference between Adobe Reader and Adobe Acrobat Reader DC? Should I stay with Adobe Reader? I'm confused! (Thanks a lot).

    New name, same thing.

    Adobe will continue to publish updates of Player 11 for a while, but they will not be security update.

    DC is actually version 15. Or 2015. Depends on how count you.
