Question about the MAXIMUM PERFORMANCE mode

An excerpt of the ML note: 239100.1

To participate in maximum performance the following requirements must be met:

    Redo Archival Process : LGWR or ARCH
    Network Transmission mode : ASYNC when using LGWR only 
    Disk Write Option : NOAFFIRM
    Standby Redo Logs : No, but recommended and required for Real-Time Apply   
What is
Standby Redo Logs : No
What means? Cannot create a database without Online redo logs. Right?

Standby Redo Logs are not the same as online newspapers. They are used only in the role of Eve (by RFS background process) to allow primary LGWR.
You always want to create them regardless of the level of protection. They are (in theory) an option with Max Performance.

    We are at the stage of the design of our installation of DR. This particular DB stores retail banking information. Each transaction is important.
    So, we thought to have standby mode Maximum protection for our side. We have a good network of low latency. We expect not to have as a standby DB.

    Lets say we have several sessions connected to the primary DB. In A meeting, for a particular Transaction if for any reason any primary DB gets acknowlegment on standby it again is applied while the session will hang. Right? What other sessions connected to the DB? They all have to wait until the transaction of A Session receives a confirmation of sleep, that take effect pending?

  • Question about the flexible reference mode vs mode


    Hi, help me to make it clear what mode should I use for my ar test?

    If anyone can answer my questions, it would be useful.

    1. mode of reference

    1.1 reference mode has some standard scenario to make VDI workload. would you share the contents of these scenarios?

    1.2 how the reference mode simulates listening login for users of 400VDI?

    2. flexible mode

    2.1 How can I decide which mode should be used for my test, the remote control mode, the passive mode and local mode?

    in other words, what kind of test cases are recommended for each mode?

    I know remote mode is 1:1 for the client and the desktop computer, passive mode is 1: n and local mode is 0: n.

    2.2 how flexible mode to simulate the time to peak of connection for users of 400VDI?

    Thank you very much.

    Ayako

    1 Yes "remote" mode and specify 400 as the number of workstations. You need 400 clients to connect.

    2. you can see the workload mix on the ViewPlanner UI page. But for the event log, you can only select the 'word'.

    3. There will be a PDF report at the end with all the stats.

  • A question about the behavior of mode full-screen (1280 x 1024 1024 x 768)

    Hey guys.

    I'm using VMware Workstation 6.5.1 on Windows 2000 SP4 as host and I use it to run Windows XP Pro SP2 on guest operating system

    My screen in the host resolution is 1280 x 1024 and I need my windows desktop will remain at 1024 x 768 in mode full-screen(due to a certain application windows that don't work well in higher resolutions).

    I have limited the maximum resolution of my guest operating system by manually adding the following two lines in the file .vmx with a text editor.

    svga.maxWidth = "1024".
    svga.maxHeight = "768".

    So when I optimized the screen in my guest operating system, I have some display problems. Big black square appears as follows the movements of the mouse pointer.

    Any feed back will be really useful.

    Thank you.

    You don't need to change the settings of the virtual machine to do this. Go to Edition-> Preferences-> display-> check "Invited Stretch" or "Guest Center" depending on how you want the guest to watch.

    This chipset is inside my laptop?

    Does he really support only 2 GB of RAM?

    I wonder if you have checked the user manual installed which must be preinstalled on the laptop.

    In any case, as far as I know that the memory on U400-10J can be upgraded up to 2 GB of RAM (2 x 1 GB).
    DDR2 667 MHz (PC2-5300) 200 - PIN SODIMM modules are compatible and it seems that the Chipset Mobile Intel GL960 Express was built in.

  • Ask questions about the functionality of EA8500 MU-MIMO

    Dear Linksys

    I bought EA8500, and it arrived today.

    I have two questions about the functionality of MU-MIMO of EA8500 AP.

    1. I want to compare the performance between SU-MIMO and MU-MIMO, but there is no option to control this feature in the router admin page. Is that one of the possible ways?

    2 EA8500 supports 1733 Mbps wireless speed, but it resembles the speed of 1 Gbps ethernet cable.

    This router supports really speed 1 Gbps ethernet? or y at - it an option to support more throughput as the aggregation of links?

    Thank you

    Hi, hyeonu. For your first query, it is not possible because there is no option to disable the feature of MU-MIMO on your Linksys EA8500 router. In addition, with regard to your second, you can get a higher throughput of 1 Gbps since this is the maximum capacity of your ethernet connection.

  • Question about the differences in commands

    Hey guys -.

    I just had a few questions about the differences between orders that seem to perform the same function.  Can you let me know if an order is more preferable to the other and what the difference is.  I would really appreciate it as it I currently practice some INE laboratories and I see that orders change from lab to lab.  Thanks advance!

    1. When you write a static NAT for specific host 1 - is - this important if I understand the 32 subnet?

    EX: static (inside, outside) 1.1.1.1, 2.2.2.2 VS static (inside, outside) 1.1.1.1 2.2.2.2 netmask 255.255.255.255

    2. when I'm setting up a router as a CA server and it is necessary to "export" the key, whatever my method of exporting the key?  If so, in which method call for which solution?

    EX: key export cryptographic rsa ciscox pem URL nvram: cisco VS. exporting key 3des cryptographic ciscox pem 3des rsa terminal cisco

    3. If I have to mark a packet with a DSCP of X value, matter if I use the 'set dscp' VS 'set ip dscp?  If so, what is the difference?

    FXY

    Policy-map X

    class X

    the dscp X value

    VS

    Policy-map X

    class X

    X ip dscp value

    I guess pertaining to 2, if i was speaking in terms of from a cisco router to another cisco router - would terminal be acceptable?

    Yes, the "Import cryptographic key" command can take a url and also from the terminal entrance. In this terminal case wil is much easier.

  • Questions about the implementation of clusters of storage and DTS on active cluster

    I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

    We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

    Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

    Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

    What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

    I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

    If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

    I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

    Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

    Thanks in advance for your comments.

    Hello

    Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

    Gregg

    With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

    Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

    In short: don't go there.

  • A question about the virtual processors in the prompt

    Dear Sir

    I have a general question about the number of virtual processors in the guest system.

    I use VMware ESXi 4.0.

    Say if my physical host has only 2 cups carrots (with or without HT should be the same), then is - it true that I can only attribute 2 virtual processors per virtual machine?

    Is it possible to give 4, 8 virtual processors in virtual machines?

    In my drop down menu I can NOT choose more than 2 virtual processors per virtual machine, I want to just make sure that it is not the problem of license.

    Thank you very much.

    Hi Nanfang,

    linanfang wrote:

    So the general rule is the number of vcpus don't CAN NEVER exceed the number of physical processors. Is this correct?

    Replace "physical cpu" by "physical cores" and you are right, because a vCPU is mapped to a kernel. For example, you can assign 4 vCPU with a Quad-Core processor.

    If you think about it, it makes perfect sense. If you would be able to map 2 vCPU to the base, the vCPUs had to wait for them all the time because the physical kernel can simply perform an action at a time, why you would decrease the performance of your virtual machine by setting 2 vCPUs.

    It is not changed in vSphere 5.

  • Question about the need to connect every 30 days...

    I understand the need for CC programs to connect to license Adobe servers, every 30 days (or it's 99, since I have an annual license?) of re - check license status.  That said, I have a question about the timing of these connections the licence renewal.

    What happens if I happen to be disconnected so far here 30?

    With the help of Microsoft for example...  I need Visual Studio to reactivate my developers license every 30 days in order for me to develop applications Windows 8 'metro '.  If I happen to be disconnected so far here 30, I am unable to work on any apps 'metro' until I got online.  (And I don't see any way to tell him to reactivate at the beginning).

    What happens with Adobe CC?

    Suppose I have license, and I am online for 29 days.  Then, the 30th day, I find myself be in offline mode when I start one of the programs of CC.  Now what?  Does the 30-day clock 'reset' every now and then during this time, or is it really only try every 30 days, and I have to be online on that day?

  • Question about the sizing of the portalControlTreeCache

    I have a question about the sizing of the WLP caches that are based on the number of users of the portal in general and the portalControlTreeCache in particular. Are the caches replicated on servers managed in a cluster, or specific to each server? So if I have 4 servers in the cluster, and the maximum number of users at the same time for my application I expect 10000, I can set the size of the cache to 2500 + -, or should I size to 10000 + -?

    Thank you!

    Cache is not replicated on the nodes in the cluster. The number of entries in cache per cluster node will vary with load balancing algorithm and your stiffness of the session. You should also take into account what might happen if a cluster node is taken offline and users of this node now failover to the secondary server. But as a general rule, your thought process is accurate about 100,000 concurrent users / 4 knots = 2500 users per server. Note that only users who have personalized their desktop will get a controlTreeCache entry. No custom desktop computers share a single controlTree cached.

  • Questions about the export of PDF with India CS5.5

    Hey all,.

    A few questions about the export to PDF of the most recent version of India.

    First of all, I noticed it seems to take much more time to access a PDF file. Any suggestions about how to speed up the process? It took 8 minutes to generate a PDF low resolution (for printing) of a document of 24pp with placed images and vector graphics. Wow, that's a long wait, especially for evidence.

    Second, the background task... If I get it will make this PDF of 8 minutes and then more work on the document, which is exactly in the PDF? Usually, I have save before making a PDF or printing. Thus, the latest version is saved which will be in the PDF?

    (Either incidentally, this ability to work on the doc while generating a PDF file seems kind of weird. Generally, we do a PDF for proofing, or even for printing, when any changes have been made and that everything is "final". Therefore, I see no advantage in being able to work on my document while it is making a PDF file, I am probably once your revisions for the moment. I must say that I like the progress bar that you get when you perform an interactive PDF, as you know that you can not work on the document when it is on the screen...)

    Thank you as always.

    Good, people. Wanted to just follow this and post my results. It turns out that the problem is somewhere in the Illustrator file. I never had the time to guess what work plan was the culprit. Other India files PDF files is transparent and not a lot of time.

    No resolution, unfortunately, just good to know that it is not all India files on my system. Phew!

    THANK YOU for your advice.

  • Question about the guest of dashboard and column

    My question about the dashboard and column prompt:


    (1) prompt dashboard usually work with only for columns that are in the topic area. In my report, I have created some of the columns that are based on other columns. As I have the daysNumber column that is based on two other columns, because it calculates the difference between two dates. I can't find this column invites when I create dashboard. I need to make a guest on this column.

    (2) to one of the column, I have only two values 1 and 0. When I create a prompt for this column, is possible that falling of drop down it displays 'Yes' of 1 0 and 'No' and always filter the request?

    Hello...

    I forgot to tell you one thing... but performance wise... If you create the column in RPD itself, it is good and easy to maintain.
    If you want this feature also... once again you choose directly the column in the area of topic... ;)

  • 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.
