Best practice for database move to new disk

Good morning,
Hopefully this is a straight forward question/answer, but we know how these things go...
We want to move a SQL Server Database data file (user database, not system) from the D: drive to the E: drive.
Is there a best practice method?
My colleague has offered "ALTER DATABASE XXXX MODIFY FILE" whilst I'm more inclined to use "sp_detach_db".
Is there a best practice method or is it much of a muchness?
Regards,
Andy

Hello,
A quick search on MSDN blogs does not show any official statement about ALTER DATABASE – MODIFY FILE vs ATTACCH. However, you can see a huge number of article promoting and supporting
the use of ALTER DATABASE on any scenario (replication, mirroring, snapshots, always on, SharePoint, service broker).

You cannot find the same about ATTACH. In fact, I found the following article:

(Request for:) Best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC

Could you please share your best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC, that will be running on a new WinSrv 2012 r2 host server. (This
will be for a brand new network setup, new forest, domain, etc.)
Specifically, your best practices regarding:
the sizing of non virtual and virtual volumes/partitions/drives,
the use of sysvol, logs, & data volumes/drives on hosts & guests,
RAID levels for the host and the guest(s),
IDE vs SCSI and drivers both non virtual and virtual and the booting there of,
disk caching settings on both host and guests.
Thanks so much for any information you can share.

A bit of non essential additional info:
We are small to midrange school district who, after close to 20 years on Novell networks, have decided to design and create a new Microsoft network and migrate all of our data and services
over to the new infrastructure . We are planning on rolling out 2012 r2 servers with as much Hyper-v virtualization as possible.
During the last few weeks we have been able to find most of the information we need to undergo this project, and most of the information was pretty solid with little ambiguity, except for
information regarding virtualizing the DCs, which as been a bit inconsistent.
Yes, we have read all the documents that most of these posts tend point to, but found some, if not most are still are referring to performing this under Srvr 2008 r2, and haven’t really
seen all that much on Srvr2012 r2.
We have read these and others:
Introduction to Active Directory Domain Services (AD DS) Virtualization (Level 100),
Virtualized Domain Controller Technical Reference (Level 300),
Virtualized Domain Controller Cloning Test Guidance for Application Vendors,
Support for using Hyper-V Replica for virtualized domain controllers.
Again, thanks for any information, best practices, cookie cutter or otherwise that you can share.

Noticing a lot of database index fragmentation yet no Health Analyzer alerts...? Best practice for database maintenance in 2013?

Could someone point me to a document for best practices for database maintenance with SharePoint 2013? I have read the 2010 document, but I'm hoping their is an updated one that I'm just missing.
My problem is that our DBA recently noticed that many of our SharePoint databases have high index fragmentation. I have the Health Analyzer rules enabled for index fragmentation and they run daily, but I've never received an alert despite the majority
of our databases having greater than 40% fragmentation and some are even above 95%.
Obviously it has our attention now and we want to get this addressed. My understanding (which I now fear is at best incomplete, more likely just plain wrong) was that a maintenance plan wasn't needed for index fragmentation in 2010/2013 like it was
in 2007.
Thanks,
Troy

It depends. Here are the rules for that job:
Sampled mode
Page count >24 and avg fragmentation in percent >5
Or
Page count >8 avg page space used in percent < fill_factor * 0.9 (Fill Factor in SharePoint 2013 varies from 80 to 100 depending on the index, it is important not to adjust index fill factors)
I have seen cases where the indexes are not automatically managed by the rule and require a manual defragmentation with a Full Scan, instead of Sampled. Once the Full Scan defrag completed, the timer job started handling the index fragmentation automatically.

What are the best practices for Database management and performance tuning?

Hello,
I want to ensure that I am using the best practices for managing and maintaining our Database.
Is there any documentation out there that outlines how to maintain and ensure top performance out of our database?
Thank you!
John Sefton

I appreciate the responses, however this is not the information I am looking for.
I am specificaly looking for best practices invloving the managment and performance tuning.
Example: are their tools that I can install that will monitor the size and response time of the database and alert me if there is degradation in performance?
Are there specific periodic activities I should be doing to garuntee that my database will continue to function that way it is supposed to?
Or is this a fire and forget solution that does not need this attention?

Best practice for database migration in 11g

Hello,
Database migration is required due to OS change. Here, I have two database instances say A and B in the old server where RDBMS_VERSION is 11.1.0.7.0. They need to be migrated into a new OS where the oracle has been installed with version 11.2.0.2.0.
Since all data + objects need to be migrated into the new server, I want to know what the best practice is and how to do that. Thanks in advance for your necessary guidance.
Thanks and Regards,
Prosenjit

Hi Prosenjit,
you have some options.
1. RMAN Restore: you can restore your database via rman to the new host, and then upgrade it.
Please follow instruction from MOS Note: RMAN Restore of Backups as Part of a Database Upgrade (Doc ID 790559.1)
2. Data Guard: check the MOS Note: Mixed Oracle Version support with Data Guard Redo Transport Services (Doc ID 785347.1)
3. Full Export / Import (DataPump)

Best practices for managing Movies (iPhoto, iMovie) to IPhone

I am looking for some basic recommendations best practices on managing the syncing of movies to my iPhone. Most of my movies either come from a digital camcorder into iMovie or from a digital Camera into iPhone.
Issues:
1. If I do an export or a share from iPhoto, iMovie, or QuickTime, what formats should I select. I've seem 3gp, mv4.
2. When I add a movie to iTunes, where is it stored. I've seen some folder locations like iMovie Sharing/iTunes. Can I copy them directly there or should I always add to library in iTunes?
3. If I want to get a DVD I own into a format for the iPhone, how might I do that?
Any other recommedations on best practices are welcome.
Thanks
mek

1. If you type "iphone" or "ipod" into the help feature in imovie it will tell you how.
"If you want to download and view one of your iMovie projects to your iPod or iPhone, you first need to send it to iTunes. When you send your project to iTunes, iMovie allows you to create one or more movies of different sizes, depending on the size of the original media that’s in your project. The medium-sized movie is best for viewing on your iPod or iPhone."
2. Mine appear under "movies" which is where imovie put them automatically.
3. If you mean movies purchased on DVD, then copying them is illegal and cannot be discussed here.

Best Practice For Database Parameter ARCH_LAG_TARGET and DBWR CHECKPOINT

Hi,
For best practice - i need to know - what is the recommended or guideline concerning these 2 Databases Parameter.
I found for ARCH_LAG_TARGET, Oracle recommend to setup it to 1800 sec (30min)
Maybe some one can guide me with these 2 parameters...
Cheers

Dear unsolaris,
First of all if you want to track the full and incremental checkpoints, make the LOG_CHECKPOINT_TO_ALERT parameter TRUE. You will see the checkpoint SCN and the completion periods.
Full checkpoint is being triggered when a log switch happens and checkpoint position in the controlfile is written in the datafile headers. For just a really tiny amount of time the database could be consistent eventhough it is open and in read/write mode.
ARCH_LAG_TARGET parameter is disabled and set to 0 by default. Here is the definition for that parameter;
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams009.htm
If you want to set this parameter up the Oracle recommends it to be 1800 as you have said. This can subject to change from database to database and it is better for you to check it by experiencing it.
Regards.

Best practice for database calls from Java components?

I have a java component that encapsulates some complex database logic. In unit tests, I pass in a jdbc connection.
Is there a way to pass in a database connection from PBL for a database defined as an External Resource in an ALBPM project? That way, I can test it using the "abstract" definition in the project and know that when it is deployed to production it will use the concrete definition. And, I won't have to maintain a separate configuration of the JDBC url.
Is there a better way to do this? Or is it possible?
Thanks,
Todd

Hi Bruno,
The main issue with the combination of stateful session beans and servlets is the servlet threading model.
It is dangerous to store a stateful session bean reference in servlet instance state, since the servlet instance
can be accessed concurrently, yet a stateful session bean reference is intended to be used by only one
client.
As you point out, one alternative is to store the reference in the HttpSession. That associates the reference
with a particular client, which matches the stateful session bean programming model.

Best practices for creating movie from still images?

I have created an architectural model in *someone else's* software, and animated a camera in *someone else's* software, and rendered that out to still images. I rendered every 5th frame (for a total of 401 frames) in order to save time on rendering. My goal is to create a short movie (2 minutes) of the camera flying around the building.
When I imported all of the images, I stretched the duration so that they equally fit the 2 minutes, and used the keyframe assistant to sequence the layers. Now that I've done that, the movie is choppy (as I expected it to be, since I only rendered every 5th frame). Does anyone have suggestions as to what effect or transition can be used to smooth the sequence out? Or am I living in a dreamland and I need to go back and render every single frame? Is this even the software I should be using? I'm obviously a n00b, so any help is greatly appreciated.
Thanks!
Using After Effects CS4 (9.0.0.346) on Windows 7 64-bit

Or am I living in a dreamland and I need to go back and render every single frame?
You are. There is no effect that could automatically synthesize those missing frames even halfway realistically. Timewarp and Twixtor are only gonna make things look like a smear even with a lot of tweaking. By the time you have tweaked their settings and done all your masking and otehr corrections, your 3D render with all frames will be finished just as well and offer better quality.

Best Practice for the database owner of an SAP database.

We recently had a user account removed from our SAP system when this person left the agency. The account was associated with the SAP database (he created the database a couple of years ago).
I'd like to change the owner of the database to <domain>\<sid>adm (ex: XYZ\dv1adm) as this is the system admin account used on the host server and is a login for the sql server. I don't want to associate the database with another admin user as that will change over time.
What is the best practice for database owner for and SAP database?
Thanks
Laurie McGinley

Hi Laura
I'm not sure if this is best practise or not, but I've always had the SA user as the owner of the database. It just makes it easier for restores to other systems etc.

Best Practices for new iMac

I posted a few days ago re failing HDD on mid-2007 iMac. Long story short, took it into Apple store, Genius worked on it for 45 mins before decreeing it in need of new HDD. After considering the expenses of adding memory, new drive, hardware and installation costs, I got a brand new iMac entry level (21.5" screen,
2.7 GHz Intel Core i5, 8 GB 1600 MHz DDR3 memory, 1TB HDD running Mavericks). Also got a Superdrive. I am not needing to migrate anything from the old iMac.
I was surprised that a physical disc for the OS was not included. So I am looking for any Best Practices for setting up this iMac, specifically in the area of backup and recovery. Do I need to make a boot DVD? Would that be in addition to making a Time Machine full backup (using external G-drive)? I have searched this community and the Help topics on Apple Support and have not found any "checklist" of recommended actions. I realize the value of everyone's time, so any feedback is very appreciated.

OS X has not been officially issued on physical media since OS X 10.6 (arguably 10.7 was issued on some USB drives, but this was a non-standard approach for purchasing and installing it).
To reinstall the OS, your system comes with a recovery partition that can be booted to by holding the Command-R keys immediately after hearing the boot chimes sound. This partition boots to the OS X tools window, where you can select options to restore from backup or reinstall the OS. If you choose the option to reinstall, then the OS installation files will be downloaded from Apple's servers.
If for some reason your entire hard drive is damaged and even the recovery partition is not accessible, then your system supports the ability to use Internet Recovery, which is the same thing except instead of accessing the recovery boot drive from your hard drive, the system will download it as a disk image (again from Apple's servers) and then boot from that image.
Both of these options will require you have broadband internet access, as you will ultimately need to download several gigabytes of installation data to proceed with the reinstallation.
There are some options available for creating your own boot and installation DVD or external hard drive, but for most intents and purposes this is not necessary.
The only "checklist" option I would recommend for anyone with a new Mac system, is to get a 1TB external drive (or a drive that is at least as big as your internal boot drive) and set it up as a Time Machine backup. This will ensure you have a fully restorable backup of your entire system, which you can access via the recovery partition for restoring if needed, or for migrating data to a fresh OS installation.

Best Practice for Distributing Databases to Customers

I did a little searching and was surprised to not find a best practice document for how to distribute Microsoft SQL Databases. With other database formats, it's common to distribute them as scripts. It seems that feature is rather limited with the built-in
tools Microsoft provides. There appear to be limits to the length of the script. We're looking to distribute a database several GBs in size. We could detach the database or provide a backup, but that has its own disadvantages by limiting what versions
of the SQL Server will accept the database.
What do you recommend and can you point me to some documentation that handles this practice?
Thank you.

Its much easier to distribute schema/data from an older version to a newer one than the other way around. Nearly all SQL Server deployment features supports database version upgrade, and these include the "Copy Database" wizard, BACKUP/RESTORE,
detach/attach, script generation, Microsoft Sync framework, and a few others.
EVEN if you just want to distribute schemas, you may want to distribute the entire database, and then truncate the tables to purge data.
Backing up and restoring your database is by far the most RELIABLE method of distributing it, but it may not be pratical in some cases because you'll need to generate a new backup every time a schema change occurs, but not if you already have an automated
backup/maintenance routine in your environment.
As an alternative, you can Copy Database functionality in SSMS, although it may present itself unstable in some situations, specially if you are distributing across multiple subnets and/or domains. It will also require you to purge data if/when applicable.
Another option is to detach your database, copy its files, and then attach them in both the source and destination instances. It will generate downtime for your detached databases, so there are better methods for distribution available.
And then there is the previously mentioned method of generating scripts for schema, and then using an INSERT statement or the import data wizard available in SSMS (which is very practical and implements a SSIS package internally that can be saved for repeated
executions). Works fine, not as practical as the other options, but is the best way for distributing databases when their version is being downgraded.
With all this said, there is no "best practice" for this. There are multiple features, each offering their own advantages and downfalls which allow them to align to different business requirements.

Best practice for partitioning 300 GB disk

Hi,
I would like to seek for advise on how I should partition a 300 GB disk on Solaris 8.x, what would be the optimal size for each of the partition.
The system will be used internally for running web/application servers and database servers.
Thanks in advance for your help.

There is no "best practice" regardles of what others might say. I depends entirely on how you plan on using and maintaining the system. I have run into too many situations where fine-grained file system sizing bit the admins in the backside. For example, I've run into some that assumed that /var is only going to be for logging and printing, so they made it nice and small. What they didn't realize is that patch and package information is also stored in /var. So, when they attempted to install the R&S cluster, they couldn't because they couldn't put the patch info into /var.
I've also run into other problems where a temp/export system that was mounted on a root-level directory. They made the assumption that "Oh, well, it's root. It can be tiny since /usr and /opt have their own partitions." The file system didn't mount properly, so any scratch files in that directory that were created went to the root file system and filled it up.
You can never have a file system that's too big, but you can always have a file system that's too small.
I will recommend the following, however:
* /var is the most volatile directory and should be on its own several GB partition to account for patches, packages, and logs.
* You should have another partition as big as your system RAM and assign that parition as a system/core dump for system crashes.
* /usr or whatever file system it's on must be big enough to assume that it will be loaded with FOSS/Sunfreeware tools, even if at this point you have no plans on installing them. I try to make mine 5-6 GB or more.
* If this is a single-disk system, do not use any kind of parallel access structure, like what Oracle prefers, as it will most likely degrade system performance. Single disks can only make single I/O calls, obviously.
Again, there is no "best practice" for this. It's all based on what you plan on doing with it, what applications you plan on using, and how you plan on using it. There is nothing that anyone here can tell you that will be 100% applicable to your situation.

New mac - what is best practice for accounts?

I am about to get a new mac (imac g5), and would like it to work well (ie file transfer and backup to from) my existing powerbook.
Is there a best practice for account set up? should I use the same accounts between the two or can I set up a new account on the new mac?
Related to this: what will key change sync give me? does that only work with the same accounts on two macs?
thanks
John

With Tiger there is a migration assistant that will move everything over from your Powerbook to your new iMac G5. All you need is a firewire cable and when prompted in your first start-up select migration assistant and connect the two computers. You will need to boot up your Powerbook holding down the 't' key before you connect the two together. Good luck, Jack.

BEST PRACTICES FOR CREATING DISCOVERER DATABASE CONNECTION -PUBLIC VS. PRIV

I have enabled SSO for Discoverer. So when you browse to http://host:port/discoverer/viewer you get prompted for your SSO
username/password. I have enabled users to create their own private
connections. I log in as portal and created a private connection. I then from
Oracle Portal create a portlet and add a discoverer worksheet using the private
connection that I created as the portal user. This works fine...users access
the portal they can see the worksheet. When they click the analyze link, the
users are prompted to enter a password for the private connection. The
following message is displayed:
The item you are requesting requires you to enter a password. This could occur because this is a private connection or
because the public connection password was invalid. Please enter the correct
password now to continue.
I originally created a public connection...and then follow the same steps from Oracle portal to create the portlet and display the
worksheet. Worksheet is displayed properly from Portal, when users click the
analyze link they are taken to Discoverer Viewer without having to enter a
password. The problem with this is that when a user browses to
http://host:port/discoverer/viewer they enter their SSO information and then
any user with an SSO account can see the public connection...very insecure!
When private connections are used, no connection information is displayed to
SSO users when logging into Discoverer Viewer.
For the very first step, when editing the Worksheet portlet from Portal, I enter the following for Database
Connections:
Publisher: I choose either the private or public connection that I created
Users Logged In: Display same data to all users using connection (Publisher's Connection)
Users Not Logged In: Do no display data
My question is what are the best practices for creating Discoverer Database
Connections.
Is there a way to create a public connection, but not display it in at http://host:port/discoverer/viewer?
Can I restrict access to http://host:port/discoverer/viewer to specific SSO users?
So overall, I want roughly 40 users to have access to my Portal Page Group. I then want to
display portlets with Discoverer worksheets. Certain worksheets I want to have
the ability to display the analyze link. When the SSO user clicks on this they
will be taken to Discoverer Viewer and prompted for no logon information. All
SSO users will see the same data...there is no need to restrict access based on
SSO username...1 database user will be set up in either the public or private
connection.

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information
