Question about Active Dataguard

Version: 11.2
Operating system platform: Solaris 10

I've only worked with 10 gr 2 physical standby databases. Now we will install 11.2 on solaris.
Read about 11 g Dataguard active characteristic of what applications can connect to the DB in waiting for read only operations.
Once Dataguard Active is enabled (to learn), if the main BP is heavily loaded and a session triggered an intensive resource SELECT query, process that will redirect the SELECTED for the less loaded standby DB? Is the listener as it does in the CARS?

Hello;

Active Data Guard is a database of "Reader". I don't think there is a process that turns automatically off of load to it.

If its great for reporting etc.

Another option Active Data Guard, is that it allows fast incremental backups RMAN on the Active Data Guard physical standby.
It is another potential way of unloading of a treatment of the database of the database pending production.

Active Data Guard is an option to license additional and another that some alter database controls its pretty simple.

alter database recover managed standby database cancel;
alter database open;

  • MaxPageSize problem/Question about Active Directory in my organization.

    Hello guys, I'm having a weird problem with Active Directory in my organization.

    Long story short:

    In my environment, the MaxPageSize value is the default value (1000), and MaxValRange also has by default (1500).

    However, in the Exchange Event Viewer, I see the existing event several times below:

    A ldap directory SRV1 Server search results. DOMAIN.COM has exceeded the administrative limit. Only the first 100 entries have been returned successfully by the search request.

    My question is: If the MaxPageSize controls the number of objects returned in a single search result, and it is currently set at 1000, why Exchange sees only the first 100 entries of each search?

    Any help would be greatly appreciated.

    Thanks in advance :-)

  • Question about activation of Windows 7 Edition upgrade Home Premium to Windows 7 Ultimate

    Hi all

    I've recently updated the OS on my computer laptop from Home Premium (Windows 7) supplied with the computer (I have activated the product) to ultimate (Windows 7) using an upgrade key.  Now when I turn on my computer it says 3 days until automatic activation or activate now.  I clicked activate now, but I apparently don't have the right key.  I tried the upgrade button, but I was told that it cannot be used to activate the operating system.  I also tried my original laptop computer product key but I was told that it will not now work with my copy of Windows 7 Ultimate.  I don't know what I can do.  What will happen in 3 days?  Can someone tell me if I have anything to worry about and what I can do to solve?  Thanks in advance!

    -Looks

    First of all, where did you get your Windows 7 Ultimate license?

    Windows 7 Ultimate upgrade came with a product key?

    What type of upgrade, you did do, was an Express upgrade or did you do a custom clean install?

    This is probably why you are experiencing the problem.

  • Small questions about Dataguard

    Hello

    I have a few questions about Dataguard. I'm new to DG, carry me so for the display of these fundamental questions:

    We plan to install Oracle 12 c to Win 2012 R2 with primary and physical intelligence on different physical servers. We are looking for HA solution, but cannot afford to license CARS. The two primary & Eve are going to be in the same data center connected via a 1 gigabit network. So I have a few questions related to it.

    (a) since both of our primary & Eve is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

    (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

    (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

    (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

    (e) I was reading about the modes of Protection, account required to our current situation & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

    (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

    Concerning

    Learner

    (a) since both of our main & secondary is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

    Well it will not provide the level of HA that is RAC. RAC is a Transparent Application failover. With a physical standby, you need to apply some delay for a failover operation. You can implement the observer that can automate the failover and reduce the time.

    (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

    This isn't really the DG broker, but rather the observer you will need to implement. The DG broker automate failover. It will be the observer who "sees" (where its name) that the principal is down and initiate the failover process. To do this, the observer will use the DG broker, so it will be necessary.

    (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

    You'll want to read on the QuickStart failover. http://www.Oracle.com/technetwork/articles/smiley-fsfo-084973.html

    (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

    The DG broker is required to run on the database server. The DG broker will run on the primary and standby. I think that what you're asking really anything is if the observer can run on a PC. Yes it can. However, it is probably not a good idea. A PC will not have the internal hardware redundancy, a server can have. If the PC can fail more often than to a server. And if the gods are bad, it will fail when you most need.

    (e) I was reading about the modes of Protection, account required to our current scenario & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

    Your choice should depend on the amount of data loss is acceptable.

    (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

    Oracle integrated security only works on Windows with a MS Failover Cluster. Real DBAs do not have Oracle on MSFC.

  • 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.

    I bought a Dell installation disk and I want to use it to install a better version of Windows on my Dell PC. I have windows Vista and I want to use it to update my OS Windows7 Home Premium.

    I have question about the figure:
    'D.1.2 putting into place of a primary of multiple instances with a multi-Instance standby'
    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14239/IMG/rac_arch.gif

    page http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/rac_support.htm

    Detailed explanation is provideded here:
    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14239/img_text/rac_arch.htm

    It is said:
    «This illustration shows a primary database archiving online redo logs to a database, multi-instance multi-instance ensures in a Real Application Clusters environment.» In this configuration, there are two instances of primary database: has the instance primary and primary Instance B. There are also two instances of sleep: standby receiving Instance C and standby recovery Instance D. The definition and purpose to receive the bodies and recovery is described in the text that follows this illustration. Each primary instance uses a LGWR to write again online newspapers and recovery logs archived local processes on the primary instance. In addition, the process LGWR on the primary Instance a sends its changes over an Oracle Net network to the RFS in First Instance B process and to the RFS process on Standby receiving Instance C. primary Instance B sends its changes over an Oracle Net network to the RFS on Standby Recovery Instance D process. The RFS process on each standby instance written in local newspapers do sleep. This figure also shows how the process ARCn on Standby receiving Instance C sends its changes over an Oracle Net network to the process on Standby Recovery Instance D RFS. The process on Standby Recovery Instance D ARCn also archives its changes in newspapers local archived redo. »

    Question I would like to ask because I'd like to better understand the Internals:
    (1) why it is written that LGWR writes Archives newspapers and not ARCH process? Is this some sort of error doc. ?
    (2) what is the reason that LGWR sends redo changes made to the FIU to the instance of the same (primary) cluster? What is the purpose? What happens if it has many nodes in the primary? This means that this instance would be multicast it to each of them in this way?
    (3) on the backup site: MRP is located on the D instance in this scenario? (1 single standby instance is applying the data but several can recive redo and write it to the SRls)?

    (1) why it is written that LGWR writes Archives newspapers and not ARCH process? Is this some sort of error doc. ?
    Yes, it seems that this picture has been simplified, and it does not show the level of appropriate detail.
    (2) what is the reason that LGWR sends redo changes made to the FIU to the instance of the same (primary) cluster? What is the purpose? What happens if it has many nodes in the primary? This means that this instance would be multicast it to each of them in this way?
    This shows what we call "cross instance archiving". If you enable this, one storing data on multiple nodes. So if you are in a cluster, and archive locally, if this node dies, so how you get that archive the data to retrieve, put the archives in several places gives you extra security for those who are paranoid. I think that it was more useful in the days where Oracle shipped just archiving logs, now that lgwr writes to the remote node, you are less likely to need it.
    (3) on the backup site: MRP is located on the D instance in this scenario? (1 single standby instance is applying the data but several can recive redo and write it to the SRls)?
    Yes one instance applies to the remake.

    I have a question about my laptop. I have notticed it is a second location of HARD disk on the bottom.
    Is it possible to use this to increase my storage?
    And if yes, how do I do that? I don't see all the connectors.
    What type of HARD drive to use in case it is possible to use this slot machine?

    My second question is on my laptop to be very hot after a short period of use.
    I installed speedfan to record the temperature. When I start the laptop, it already is between 45 and 50 degrees.
    He stayed there for half an hour and then it starts to get warmer. When I start to use the laptop for anything, it triggers to between 70 and 80 degrees.

    This does not seem normal to me. I tried to clean the vents with compressed air, but it has not made a difference.
    I searched on the internet how to take the laptop part for proparly cleaned TI.
    But I can't so I'm looking that destroy it.

    This could be the cause and more importantly, how can I solve this problem?

    Tom

    The second HARD drive bay contains the HARD drive connectors?
    If Yes, then you can use a SATA 2.5 HARD.
    If there are no connectors, then you will not be able to use the second HARD drive

    CPU and GPU produce a lot of heat. The heat dissipation is always created then there s nothing unusual that the temperature rose to higher level.
    You can change the settings in Win 7 power management. You can set the CPU to lower performance and can increase the activity of fan, which will help lower the temperature.

  • question about the mixture of OSes

    I have a question about installing a dual boot.

    Someone recently bought a copy of Windows 7, but they had the wrong version. They got the 32-bit version instead of the 64-bit and for some reason the store refuses to return or Exchange it.
    They offer it to me that they have to buy the 64-bit version.

    I'm not sure if I need it, but I thought I could try on my laptop. I just realized that I type that they never told me what version of Windows 7 it is.

    This laptop was given to me second hand. It came with Vista Home Premium. I installed XP on another partition, and was so pleased with the results that I've never bothered to fix the Vista partition to get the job to dual-boot.

    If this proves to be Windows 7 Professional or Windows 7 Ultimate edition, am I having difficulties to the upgrade of the Vista partition? I guess I could install it from scratch, but I'm not sure if all the drivers are available.
    Can I try the drivers Vista 7 the way you sometimes try 2000 drivers under XP?

    As you can see, I have several issues of concern. 7 same detects the installation of Vista and make an update if I don't fix it so that the Vista bootloader is present? The XP installation program has replaced the Vista bootloader, and I've never bothered to fix it.

    Finally, is there another recourse that the store for my friend Exchange 7 32-bit 64-bit 7 to save money?

    Looks like somebody bought an OEM of Windows 7 version from a "commercial" version comes with a 64-bit and 32-bit installation DVD.  If someone has already installed and active that the OEM 32-bit version, then, unfortunately, this license cannot be used on another computer since the OEM licenses are permanently tied to the first computer it's installed and activated on.
