A question about the design

• Philosophical question about the design of the table

  I'm new in the world of RDBMS. I read a lot but have little practical experience. I'm upgrading of old applications that I know well. I'm interested in advice/opinions on a number of issues, from it.
  
  My application periodically (at the discretion of the user, so can be daily, weekly or monthly) should take a snapshot of some data. This snapshot is then used for various activities, such as a control point of reconciliation with external clients - so it must be 'frozen' rather than be derived at a later date. But if the snapshot proved to be a mistake, I can possibly be rerun (crushed) - requiring all lines to delete everything first.
  
  Data must be accessible in different ways, everything would need the date of snapshot to be part of the index or a group of clauses.
  
  Snapshots can be copied or replicated to other servers for purposes to relieve the burden of filing database. Old clichés may be archived, ignored backups of routine, deleted and so on.
  
  Is there a case for the inclusion of the date of snapshot as part of the name of the table? It would simplify the index structures, reduce the size of the individual table, perhaps to improve the competition (for users who access an old cliché while another is being created), facilitate separate archiving and much easier to drop and create table to remove all the lines before a replay. Of course, it reduces the size of the table that could potentially become very large.
  
  However, the previous snapshot is used as a starting point for the following, or a subsequent repeat) you need to be able to quickly determine who is the nearest date start - easy if they are all in 1 table, can be more load trying to determine is whether a specific table at the time to a given date.
  
  I look forward to some expert advice. :)

  No--not from a point of view of the data modeling. The snapshot date is an attribute. Attributes are not incorporated in the name of the entity being modeled.

  However, you can decide to implement the instant entity tabular instant daily - but the attribute date (column) will always be an attribute. In other words, you must not remove the attribute date as a table column as the table name now.

  This decision (implemented as a multi table entity) have meaning when not having is not a better way to manage the physical aspects of the table. Partitioning for example would be a much better option to use - a single partitioned table, containing multiple partitions, where a partition physically contains data for a specific instant day (including the index).

  Basically, there is a very clear line between the logical data modeling and the material realization of this model. Oracle provides a bunch of features that you can use on the side of the material realization. As index organized tables. Table of clusters, partitioning and so on. But how you implement the physical model does not dictate the design of the logic model.

  However, the previous snapshot is used as a starting point for the following, or a subsequent repeat) you need to be able to quickly determine who is the nearest date start - easy if they are all in 1 table, can be more load trying to determine is whether a specific table at the time to a given date.

  I would use a management entity - that describes the metadata for a snapshot. As when it was created, the filter criteria used, the time it took (still useful for performance and troubleshooting purposes), be it an an active/valid capture instant or not - or any other attributes necessarily to manage this logical snapshot as a set of data.

  The biggest problem with a physical model that uses separate physical tables for the same entity, it is appropriate to use table name must be determined at run time. This means dynamic SQL. Dynamic SQL means an increase in complexity, open any SQL injection holes, having to deal with errors which would not intervene with static SQL, etc.

  If this approach to your data model's physical implementation needs a review carefully to ensure that it works as efficiently and effectively as required.

• A few questions about the design of Data Guard

  Hi, I have a few basic questions around design Data Guard

  Q1. Looking at the instructions of Oracle for the creation of a logical standby, he recommends first creating a physical standby and then convert waiting logic. However, I thought that a logical standby might have a totally different physical structure of the primary. How can this be the case if a logical standby first starts his life pending physical (where the structure must be the same)?

  Q2. It is a normal practice to back up your database before as well - if yes why?

  Q3. Can RMAN back up a database of the day before while he is in the State mounted (rather than opening it)?

  Q4. What is the point of cascade redo apply rather than just get the primary ship to each standby?

  I guess you could try to reduce the latency of node to node if some the day before were quite remote from the primary

  Q5. Is it possible to convert a physical logical Standby?

  Q6. What number best of Standby, you can have - Oracle suggests 30 but I thought I remember reading somewhere regarding the 11 GR 2, that this limit has now been increased?

  Thank you

  Jim

  Hello again;

  "begins each logical waiting first her life on hold physical?"

  Its the only way I ever did. I think it is the simple way to do it.  By the presence of a physical standby first you have already confirmed the network and most of the settings for Data Guard so that you can focus on only the logic of the standby database configuration.

  Chapter 3 of this book, it's easy:

• Question about the design of conditional text

  Posted in the wrong forum, post again here.

  I have a relatively important book (230 pages) with dozens of tables and 100 graphics. I need 4 versions of this book. One for each grade level (3) and the other if happy for all 3 grades is sold as a "master class".  Other than the implementation of conditional text, the book is ready to go. I tried two different ways to approach the tables under certain conditions (some of which are within blocks of text, some just anchored to a page) but I do not quite understand.  Application of conditional text tags (with different colors and markers for each) seems to crash (i.e. almost duplicatable unlike the grave 'normal' down 3-4 I feel daily last month that are just randomly). Sidenote: I was very happy to see that they will solve the crash of book printing...

  Reference markers are involved in these conditional sections, and I have my suspicions that they are guilty of the root of my other problems of crash, but then FM crashed when applying conditional text to a section that * don't * have a x - ref, so I don't know what to think.

  I need to get out Monday. So my question is, if I need 4 tables in one page (one for each version) I better just do 4 copies of the book and the compilation of this way? I sold the customer on FM mainly due to the ability to compile several book of basic documents... so, I really hate to have 4 copies when I give the source. I know that you can select rows in a table for a version (so I could do a very large table for 3 versions and simply choose different lines), but this is one thing that seems almost certain to make it crash as well.  And the paintings of masters have an extra column, but also a line so I still need 2 tables by doc so I could get the conditional statements to stop crashing. Is there a better way to 'design', which could suggest an experienced FMer? Some custom utility which works even if it isn't free?

  Just in case someone asks:

  The system configuration

  FM 11

  new facility in August, not upgraded

  All the files are originally from FM11 and new

  Windows 7-64 bit

  20 GB of memory

  2 TB - local disc c /.

  Thanks for your suggestions on this.

  Well, it didn't crashed this morning when I put the x back references in the conditional table. Sent to fmerror with the steps for dupe.

  But on the mif wash. I've done it "manually" once a week now for the last two weeks. Can't say if it is to help, but it is always recommended, so I do. However, I was wondering if anyone had a recursive script that would do this automagically...

  Thank you

  Laurie

  Edit:

  Search mif washing (and variants) and nothing gets on the Adobe site. I figured out through a vague reference to an old thread where to find it and thought that I note for new users: If there is...

  Book MIF Wash is that a utility provided by Adobe that recursively traverses all the files in your book, opens, writes the .mif file then re-recorded this file to your FM - washing apparently file everything watered in your FM file. Manually, this process takes forever. And even if you see frequent references to: did you do a mifwash yet? "when someone has a problem, there is no documentation on what I found.

  It is a "sample" allowing Adobe script.

  Go whenever you have installed FrameMaker and navigate to the BookMIFWash folder or browse to the file BookComponentMIFWash.dll, which in my case was to C:\Program Files (x 86) \Adobe\AdobeFrameMaker11\Samples\ScriptsAndUtilities\BookMIFWash.

  Copy the file BookComponentMIFWash.dll in C:\Program Files (x 86) \Adobe\AdobeFrameMaker11\fminit.

  Restart the console.

  Then you will see that nothing has changed.  ;-)

  You must select the book with your mouse in the Document window, and then the menu item utilities book "dynamically" appears. Down there, you will find some MIF Wash book.

  I always pay attention to the warning to make sure that I have a copy of the entire project before running it. :-)

  Hope this helps someone else.

• A small question about the design: black on white or white on black

  When in a black and white design, a symbol in black on a white background is reflected in the opposite colors, white symbol on a black background seems thicker to me. The image of the sample, the bulb on the right looks like more thick for me.

  Are my eyes just poor, or is this an optical illusion?

  If it's an optical illusion, in a real design would it be acceptable to the symbol in black on white background really thicker to compensate? An example where something like that could happen would be a coat-of-arms.

  Thanks for any ideas you may have for me!

  Everything is the same size and scale properly as you can see using leaders... If so, just an optical illusion. If it were me, I'd leave it.

• Question about the design of VCS-C/VCS-E

  Hello

  Customer has no DMZ. So, what are my options to configure a deployment of VCS-C/VCS-E?

  How is it I could reach the goal that VCSC and VCSe contact area of neighbor?

  Do I need to assign an internal IP address (without static nat) and LAN2 in also an IP address in-house with NAT static external IP LAN1.

  Prerequisite for which is 'Dual touch Option NIC', no?

  At the moment I have no double key Option of NIC, then the only way in my deployment is the DMZ preffered way, right? Or make me another option?

  Concerning

  Thorsten

  Well, in this case, you can have the VCS-E in public, VCS - C behind the firewall and an area between the two.

  You can increase the security nat'ing and with who use dual NICs on the VCS-E option.

  I also either turn off or at least to block SSH on VCS-E to the public.

  I understand now, thanks for the clarification.

  WebWorks applications, like all other applications on the BlackBerry OS, cover the full screen by default.  If you want to include in your application, your own taskbar to display information at the level of the system (battery, carrier, time, etc.), you need to include this logic in the application itself (for example to create a)

• Question about the new Yoga 10 HD +.

  Hello

  A few questions about the new Yoga 10 HD + that I hope you can answer.

  I bought the former model, last year. Love the design and long battery life, but a few major questions made me return.

  • Somewhere that I've read that it can not read NTFS on USB so I guess that's the same thing with a NTFS formatted microSD card?
  • Can it read exFAT formatted microSD cards?
  • Anyone who has questions about the audio via bluetooth?
    (I know that BT is not exactly High End HiFi but the old 10 Yoga for some obscure reason - most likely a driver problem which nobody cared to fix - rang * very * worst with visibly distortion while both my phone and a Tablet noname cheap I have zero about fidelity - any of my devices bluetooth audio) I tried aptX or not)

  So to avoid buying it back it also I really I would like to see if I can get my questions answered before buy you.

  While I love the form factor and long term issues above are only two Mayor dealbreakers for me. Bad audio quality = no joy listen to spotify, local etc. MP3s. not of NTFS or exFAT = some great movies.

  My old noname android Tablet really could use an upgrade so I'm really curious it may be, or I should watch the competition and will be form factor and battery LIFE.

  Thanks in advance.

  EDIT:

  If it does not support NTFS or exFAT on microSD card have someone at - he tried ext3 or ext4?

  I mean with Linux Android root, it should be a no-brainer to support at least when it comes to royalties unlike NTFS or exFAT where it * might * have some trouble with Microsoft.

  I used a USB through a USB OTG cable. NTFS or exFAT have been recognized by the Tablet PC. FAT32 is seems to be the preference.

• Question about the interruptions and priming

  Hello

  I had a few questions about the startup and interruptions in a virtualized environment

  Assuming that, plenty of virtualization (no material assistance to virtualization of memory ).

  1 initialization: in an ordinary PC, the boot process starts with the BIOS, to expansion ROM, back to the BIOS and MBR secondary boot record, then grub (is it) and finally the operating system. In a virtualized environment with VMM running directly on top of hardware (Native VMM), how is the initialization of the different process, as I understand it takes BIOS-> Expansion ROM - > BIOS-MBR-> other record secondary-> VMM-> OS--> applications >. Am I right on that?

  2 breaks: VMM examines the source interruptions prior to the interruption, so in a multicore environment, assuming a 2 processor core, how the VMM decides on the kernel for which the interruption in intended, prior to shipment of the interruption. Interruptions are tag ID, said core ID?

  Thanks in advance

Am I right on that?

  It is simplistic but essentially correct.  A metaphor would be a little better thinking that the hypervisor/vmm is an operating system, except that the process on this operating system are requests or comments OSes.  If the BIOS-> OPROM-> BIOS-> MBR-> hypervisor-> init process of the hypervisor-> reviews of fork () s operating systems.  This can become blurred by the design choices (for example Xen/Hyper-V init start a coded parent hard partition that makes hypercalls privileged to fork() guest OSes; ESXi init runs a very limited subset of applications directly on the hypervisor and ESX Classic is somewhere between these approaches).

  There is a subtle distinction between "hypervisor" and "www."  The "hypervisor" is the operating system of single root (e.g. ESX) who interacts directly with the hardware and has access to everything; a hypervisor is not to be used to run virtual machines.  When we talk about a "hypervisor", the tendency is to describe something which is a BONE (although usually a minimal OS designed only to run virtual machines).  The "www" is the layer that allows a virtual machine run: it provides the interposition, virtualization and emulation services and can be plural (for example a vmm by guest operating system).  Architecture of VMware deal with these two separate components, while most other virtualization platforms merge the two.

  Strictly speaking, the interruption is not transmitted to a guest operating system - receives the hypervisor (or rather the VMM it transmits to the hypervisor), the hypervisor drivers interpret the interruption (for example reading package of NIC, I/O process of HBA, the timer tick completion), then after a new appropriate break in the guest OS.

• A few questions about the difference between the Satellite P70, L70, S70

  Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

  (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

  (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

  (3) all the three (P70, L70, S70 series) come with the same TFT panels?

  (4) of the above series, which supports mSata?

  (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

  (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

  (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

  Thank you in advance.

  > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

  What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

  (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
  As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

  I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

  (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
  See point 1). Different P70, L70, S70 models were equipped with different material parts.

  (> 4) of the series above, which takes in charge mSata?
  As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

  (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
  See point 4) not all models supports the same hardware specifications

  (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
  I don t think that SATA III is supported. I guess it would be SATA II

  (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
  Not easy to answer because there are too many models released in Europea.
  And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.

• A few questions about the upgrade on Satellite A300-144

  Sorry for the typos, English is not my mother tongue.
  I want to ask some questions about the upgrade of a300-144.

  * Some info first.*

  CPU: T2370 ([http://ark.intel.com/products/34445/Intel-Pentium-Processor-T2370-1M-Cache-1_73-GHz-533-MHz-FSB]).
  Chipset: GM965 ([http://ark.intel.com/products/29821/Intel-82GM965-Graphics-and-Memory-Controller]).

  * Questions.*

  1. my frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

  2 Intel said that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?

  3 I know, taken of my CPU is μFCPGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 ([http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB]) is a compatible processor or there are some limitations in the BIOS?

  The speed of the memory is related on the material. This means that the FSB is responsible for the limitation.
  If the FSB would allow support 667 MHz then the memory would also at this speed.

  > 2. Intel says that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?
  The memory depends on the chipset. So if the chipset supports 4 GB of RAM, you should be capable of this move to 4 GB of RAM

  > 3. I know, my CPU is? FC-PGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 (http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB) will be a compatible processor or there are some limitations in the BIOS?

  It might be possible that the new processor would be fully supported by the BIOS, but in most cases it should not be a problem if the chipset would support the new processor.
  But as far as I know the upgrade of the CPU is not supported by Toshiba or any other manufacturers of portable and its your own risk to run laptop with the new processor.

• Question about the recovery partition

  Hello.

  I have a question about the recovery of HARD drive partition.

  If I do the operation to clear the hard disk option in the wizard it will remove * all * or it will keep my partition recovery in this way I can come back later. I want to know because I would like to put on a different OS.

  I know he said he would, but caution in the PDF, I found it says that on a normal recovery too (that he would remove each partition) and I'm a little confused about how the recovery actually worked.

  Thank you.

  Hey Buddy,

  To be honest I n don't know what you mean exactly with this option to erase.

  In General, Toshiba Recovery disk will wipe your entire HDD to restore factory settings correctly. This means that if you start from that disk and follow the instructions on the screen, everything will be removed.

  In addition, the recovery disk doesn t create a recovery partition. It is not available. Disk copy just the files on the second partition in folder HDDrecovery to start an installation of HARD drive recovery.

• A few questions about the Satellite A100 PSAANE

  Hi friends,

  I have a Toshiba Satellite A 100 - PSAANE with Vista Home Basic preinstalled in it.
  Now, I have a few questions... I mention below: -.

  (1) if I want to format my laptop, I need a CD to install for Vista Home basic... then I don't have this Toshiba CD when I bought the laptop. So how do? question: How can I format it?

  (2) can I change my Vista Home Basic to windows XP? I think it's much faster than this one. is it advisable?

  (3) I have a GB of RAM in the laptop. Increase the RAM? I think that my laptop has become to slow down. is it advisable?

  (4) and on my screen, everytime I try to change my profile screen to windows Classic view, my screen begins to blink. and after a while, the screen turns off. So I can't change that. I put the color scheme of windows vista only. What to do about that?

  Please help me friends. Thanks in advance.

  Kind regards

  Hello

  Here, a few questions about the number:

  (1) usually, you should get the Vista Toshiba Recovery DVD. If you didn t receive this DVD then you can order it here https://backupmedia.toshiba.eu/landing.aspx or you could install the disc of Microsoft Vista.

  (2) of course, you can do this. I think that Win XP drivers can be downloaded from the Toshiba driver page.

  (3) Yes, you can upgrade the RAM. For more information, see your manual or search on this forum for similar topics

  (4) maybe it s associated with the graphics driver. Check if you can update. I would recommend additional check if you are using the latest version of the BIOS
