Managing the Principle and Mirrored DB's across 2 Servers.

We have mirroring set up across 2 servers with a witness server.  A1, A2 and W1 respectively.  We have 16 Databases.  Can half of the DB's on A1 be the Principle, while A2 is the Principle for the other half?   Basically
I want to understand if I can sort of balance the DB's across the 2 servers.  Some DB's being Principle on A1 and others on A2.

Hi,
Yes, you can configure some DB's being Principle on A1 and others on A2. Because Database Mirroring works at a database level.
Please note that on a 32-bit system, database mirroring can support a maximum of about 10 databases per server instance because of the numbers of worker threads that are consumed by each database mirroring session. However, these restrictions
do not apply on 64-bit SQL Server systems.
More information, please see:

  • How to handle case like Housing loan to pay the fix amount and system can deduct the principle and interest automatically in Treasury

    Dear Treasury Guru,
    I have one scenario from my client like a Housing Loan that the system can generate the principle and interest paid flow type automatically depend on interest and contract condition, I've never faced this scenario before so I'm not sure that Treasury can support or not.
    for example : Loan amount = 500,000 USD, Fix amount = 50,000 per month, Interest rate = X%
                              Payment amount               Principle           |        Interest
    1st month =               50,000           --->         15,000                      35,000
    2nd month =              50,000          ----->        17,000                      33,000                   
    3rd month =               50,000         ------>        19,000                      31,000
    Please suggest how to let the system generate the Principle and Interest flow type folllow the example above.
    Thanks
    Pongrapee K.

    Hello Pongrapee,
    I think apart from the interest condition, you need a condition for an annuity repayment with amount 50,000 - this will make sure the sum of interest and repayments are 50,000 for all periods.
    If you leave the annuity amount blank, the system will calculate the annuity in a way that the sum of interest and repayments remain constant and all the nominal is repayed at the end of term.
    But in both cases you will have to give the interest percentage in the interest condition.
    Hope this helps!

  • Different Drive Structure Between Principal and Mirror

    We havea 2-node (active/active) cluster with four failover instances installed. We use a dedicated drive for data files, one for log files and one for tempdb per instance .Predicting that we will be adding more instances in the future, we realized that we
    would run out of drive letters to set up. We intend to switch over and use mounted volumes instead that way we only use 1 drive letter per instance and will be able to add many more failover instances in the future. However, seen as we have over 150 databases
    across all current instances, reconfiguring the cluster drive setup will require a lot of time and work and is not in the immediate plans for our team (me :( ). I need to mirror as many databases as possible, based on priority, to a DR server on a geographically
    remote location. Since this server isn't setup with SQLServer yet, I was wondering if it would be a good idea to have the DR server set up with mount volumes now and establish mirroring between our production environment and the DR server that way so that
    at least half the battle is won. I am aware that the best practice for mirroring is to have the same drive structure between the principal and mirror server, however it is not a requirement. The only example issue I have seen with this set up is when you add
    a data file to a database and the DDL statements get sent over to the mirror and will fail since the drive setup will not be the same. This is something I am willing to deal with since adding data files to our databases is not something we do often, or at
    all. As new databases are added and mirrored, the WITH MOVE clause of the RESTORE statement can be used to place the files in their correct location in the mirror server.
    Other than this, are there any other things to consider for this kind of mirroring set up?
    Leroy G. Brown

    Hi Leroy G,
    According to my knowledge, you can deploy database mirroring with different drive structure. And the known issue is that if you add a file to the Principal, the DDL commands get applied across the Mirror, then your database will go into a suspended
    status until you duplicate the path on the mirror.
    However, as your post, you can use WITH MOVE option to create database on Mirror server. For more details, please follow the steps in this
    blog.
    Meanwhile, about setting up database mirroring, I recommend you review this online
    article.
    Thanks,

  • Skype for Business - Manage the .msi but not Users...

    We are considering deploying Skype for Business across our large, international organization.  Two questions:
    Can we disable the File Transfer function in the .msi we push out to everyone?  Our concern is data leakage of confidential information.
    Our central IT shared services group wants to manage the configuration and deployment of the .msi but not be tasked with managing everyone's Skype accounts and billing/funding issues.  Does Skype account creation and funding of those accounts remain with the individual Skype user when Skype for Business is used?  
    Thanks for your help.

  • Is it possible to export and import the roles and users tables?

    Hi,
    is there any possibility to export and import the role and user definitions?
    We have a SAP MDM repository with a lot of roles and users and also with a lot of changes.
    And now I'm searching for a fast and efficient way of managing the roles and users.
    Thanks and Regards, Melanie

    Hi Melanie,
    There is no export/import functionality for roles and users.  The only way to manage these in an automated way would be to write a program that uses the Java or ABAP APIs.  Both APIs expose functionality to create, update and delete roles and users.
    Hope this helps,

  • Unbreakable Linux on a Stripe and Mirror Raid

    Hi all
    I was wondering if there is any best practice with respect to the placement of the Linux OS executables on Raid storage.
    We have a 12 x 500gb disk storage unit and intend to stripe and mirror everything giving a total of 3 terrbytes.
    I was considering placing the Linux executables on the raid along with the DB files etc and would be keen to know if anyone would anticipate any problems with this configuration.
    Thanks in advance.
    Cheers

    Thanks for your reply.
    Under normal circumstances I would also put the Unix OS on local drives.
    However, as we will be running a number of Virtual servers spread over a couple of physical servers under the control of Virtual Iron, the Unix OS has to sit on the SAN.
    I was wondering if perfformance of the Unix and Oracle executables sitting on the Striped and Mirrored disks would be bad enough to dictate that I should dedicate 2 out of the 12 disks as a mirrored pair for the Unix and Oracle executables.
    Thanks for any further input.
    Regards

  • Time Machine doesn't manage the space on my external drive- no space left

    I have a 500GB internal drive and have a 500Gb external firewire drive. I have around 200Gb of music and video files but had been happily letting TM get on with things. Today i started to get an error screen saying that the external drive was out of space and the backup had failed. Does TM not manage the backups and automatically delete the oldest to make space for the newest one?
    I'm a little confused and the logic used in the help options seems to point to me either excluding items going forward (which seems counter productive) or buying a new external drive to fill up each month. Can someone please shed some light for me.

    My understanding of how this works is that hourly & daily backups "expire" & are automatically removed after 24 hours & one month respectively, but weekly backups never expire -- they are kept, as the preference panel says, until your backup disk is full.
    Thus, if your backup drive fills up, TM will try to create space by removing older, unexpired hourly or daily backups (& optionally warn you about this) to make room for new ones, but it will not remove older weekly backups to make room for new hourly or daily ones.
    If you think about it, this makes sense: a weekly backup is most likely much larger (in terms of actual file space) & contains many more files than a daily or hourly one, so it would be undesirable to delete a lot of files to make room for relatively few others.
    IOW, the drive will eventually fill up with weekly backups & at that point, it is full, period.
    Related comments:
    I believe there is no danger in using the Leopard Finder to 'delete a file' in the time-stamped folders it exposes. Because of the changes made in the file system to support TM, what happens is only the link in that folder is deleted. Links in any other folders remain unaffected. Only when you remove the last link to the actual file does the file system mark its space unused in the directory, effectively the same as a normal file delete.
    This is why just deleting an instance of a TM backed up file won't gain you more than a few bytes of drive space -- only by deleting all instances is the file space of the actual file freed up.
    For similar reasons, Disk Utility's 'erase free space' function should be safe to use on a Time Machine volume for security reasons. Just don't use any disk utilities on this or any other Leopard-formatted drive that aren't rated for use with Leopard -- they don't know about the changes in the file system & could really mess things up if (for instance) they try to rebuild the directory structure from scratch.

  • Automatic Undo Management, UNDO tablspace, and undo_segment count

    When I created my UNDO tablespace I was given 10 undo_segments:
    SQL> SELECT usn "Rollback Table", GETS, WAITS, xacts "Active Transactions"
    2 FROM V$ROLLSTAT;
    Rollback Table GETS WAITS Active Transactions
    0 1242 0 0
    1 88678 8 0
    2 83884 2 0
    3 82519 9 0
    4 85661 17 0
    5 80613 14 0
    6 82183 0 0
    7 92551 9 0
    8 78371 14 0
    9 89043 1 0
    10 75477 5 0
    The above statistic indicates I need more undo_segments. Do I need to recreate my UNDO tablespace in order to get the number of segments necessary to prevent waits or will more undo_segments be spawned eventually??
    I think I'm suffering Contention? Is there medicine?

    Compared to the number of GETS, the number of WAITS is very small. I doubt that you could ever have enough rollback segments to ensure that there were never any waits. Oracle's read consistency mechanism virtually guarantees that you will at least occasionally get waits.
    Aside from that, the point of UNDO tablespaces is that Oracle will manage the number and size of rollback segments based on the load. If you are really concerned about this, and if you have statistics indicating that waits for rollback segments are a performance bottleneck (something like a statspack report showing large amounts of time for one of the undo waits), then you can simply add more space to your undo tablespace, and Oracle will likely use it to add additional segmetns if it feels the need.

  • CPU hits the limit, and causes the network slowdown to become unuseable.

    Hi All
    School:
    Running 2 x xserves both 2 x quad cores running 10.5.6, connected to a promise raid via fibre channels, for storage of network home folders. one being an open directory Master, the other a replica.
    aprox 290 Clients are imacs running 10.5.4 and emacs running 10.4.11. This has been running fine. We upgraded 16 of the imacs to 10.5.6 when it came out, and we experienced a major kernel Panic when networked accounts logged out. We downgraded them back to 10.5.4
    Last week we bought the new "entry level" imacs, which wouldn't boot with 10.5.4, so we performed an archive and install of 10.5.6. (maybe not the best way, but time was precious) The room has 30 machines.
    When pupils now log on, the network grinds to a halt, the CPU's on both servers, maxs out at 100% (when previously it hardly ever gets near 20%) we turn the room off and all the other rooms log in.. goes back to normal...
    We had a very bad start at the beginning of september, when we were sold a raid box and xsan to work with home folders.. which didn't, leaving us we now working machines for 3 weeks, with a new head that is not into Macs.. this is giving him fuel to get rid of them (not also because the price of this room shot up considerably, because of the new specs)
    A new image has been started from scratch, but who's to say it won't happen again come monday morning...but someone MUST know what is happening here.. also, on activity monitor - afp is stating 202 threads.. regardless of how many users... Oh, and spotlight has caused major problems in the past and this is disabled across all machines....ANY help would be appreciated
    I have spoken to two major apple dealers in the UK.. still no answer...
    Thanks
    Nicola Clarke

    I think you're experiencing the issue that several others have. AFP is swamping your CPU and everything grinds to a halt.
    You'll find there's already a topic on here with something like 15,000 hits and hundreds of replies.
    AppleCare has more or less acknowledged there is a problem but I think Apple was initially strugglingly to recreate the problem.
    We're all waiting to see if 10.5.7 resolves this. Hopefully it will be released any day now.

  • Air play and mirror imaging

    Hi Im using ipad3 with the latest software, and trying to conect with my apple tv.
    Each time I turn on the airplay and mirror imaging it automatically turns itself off after a very short time, sometimes just seconds.
    It worked for a couple of days with no probs but now this is happening, Ive changed no settings.
    Can anyone help, thanks in advance

    You will need the following bandwidth to run the following:
    1080p HD movies require a recommended speed of 8 Mbps,
    720p HD movies require a recommended speed of 6 Mbps
    SD movies require a recommended speed of 2.5 Mbps.
    You might just get away with watching slide shows or listening to music.

  • OS takes up over 3 GB of space. Can I minimize this as I am struggling with constantly managing the sync which is making me think the droid alternative with iTunes app is the better approach.

    I am restricted to a 16 GB phone and am constantly struggling with space when I sync or update. I noticed today that the OS takes up over 3 GB of space as the capacity is listed at 12.68 GB. Any suggestions on this other than get an android and use the iTunes app instead? Frustrated.

    No, the OS doesn't take up over 3GB of space.
    The difference between 16GB and 12.68GB is primarily attributable to the difference between decimal math (used by every computer and component manufacturer on Earth for stating capacity in customer facing documentation) and binary math, used by processors and operating systems. This has been an issue since the 1970's.
    Think more about managing the content and apps you actually keep on the phone. If you haven't used an app in months, you probably don't need it. Don't let your phone get cruffed up with games and apps you don't use. You also probably don't need to keep your entire media library on it for when you're on the go.
    Extract photos from the phone to your computer on a regular basis then delete them from the phone as you would from any other digital camera. Sync the photos you actually want with you to the phone. iCloud Photo Library may give some relief from this once it's out of beta.

  • How best we can use the Rollback and RollbackAlways mechanism in Visual Studio Release Management Template

    Hello All,
    We need a clarification on Rollback and RollbackAlways in Release template.
    We checked a scenario for Rollback and RollbackAlways:
    In Release Template, we have the first activity as “Configure Application Pool” and then followed by a rollback action of “Create Application Pool”
    and “Create Web Site” then followed by "Code Deployment" via TFS build.
    We tested with 2 scenario’s:
    With App Pool and Web Site already existing: when triggered the build, configure
    app pool succeeded, then Rollback action was skipped (as previous action was successful), finally deploy the code executed (code deployed) and build got succeeded.
    Deleted App Pool and Web Site: when triggered the build, configure app pool failed (as no app pool existed), Rollback action executed (as previous action failed) – created app pool and web site then finally
    deploy the code executed (code deployed)
    But build failed (Error: Configure app pool action failed).
    Ideally the build should succeed as the roll back action got executed and code deployed successfully.
    Please correct us if our understanding is wrong.
    Also, Kindly let us know how best we can use the Rollback and RollbackAlways mechanism in Release Management
    Looking forward for your positive response.
    Thanks in advance.
    Regards,

    Hi Shashank,
    Rollback Always runs if any of the actions in the template failed. Rollback will run if action just above rollback fails or if any of the actions below the Rollback fails.
    Article here (http://www.incyclesoftware.com/2014/03/understanding-rollbacks-release-management/) clearly explains how Rollback and Rollback
    Always work.
    I think you come across this issue since you are using build to do the "code deployment" action. You should use the release template to do that. 
    As far as I know you cannot use Rollback to achieve condition check (App pool exist in your case) action.
    For this you can create your own Power Shell component (which checks if the app pool exist and is not create it) and add it as a tool in RM server (RM Server Inventory).
    Another option is you can follow the workaround in below thread "Answer" quoted below. That is execute Remove app pool regardless if it exist or not (which does not fail) and then create app pool.
    I was able to get it working by removing the app pool which does not fail if it doesn't exist. Removing then creating seems the long way around but it works.
    Flow:
    Remove Application Pool
    Create Application Pool

  • I am aware that many people, like me, have lost the ability to mirror their iPad, iPhone or computer with Apple TV.  Has anyone yet found a solution?  One day it worked, the next day the option to switch between the device and Apple TV had disappeared.

    Has anyone managed to resolve the problems encountered with Apple TV and the loss of ability to mirror iphones, ipads or computers?  One day it was working perfectly, from all the above devices, the next the option to switch between playing on the device or mirroring to apple tv had disappeared.  I have tried all the obvious such as updating iTunes, turning all devices off and then back on, but nothing is working.  Help please!

    Welcome to the Apple Community.
    Your problem is most certainly network related, you might try restarting your devices including your router as a temporary solution, but in the long term would be better correcting the problems with your network.
    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first.
