DFS Maintenance Practices
I have two file servers both replicating full mesh to provide redundancy for our folders and files. Both machines are running Win2012 Standard. On this machines they both have a volume each in RAID6 configuration. This is the shared volume.
We find ourselves in a position that we want to upgrade the RAID to 10 so it is necessary to destroy the volume on each server one at a time.
Therefore my question is, what is the best practice in maintaining the given namespace and ensuring that the replication does not try to replicate the wrong way thus wiping the data. So I would like it so that users can continue to work while this
is happening?
In your configuration both servers, in theory, have the same files at any given point in time. When you're ready to do the work on the severs, edit the replication schedule, in DFS mgt, for that group(s). So that it is not replicating in the
window of time that you expect to be working the server.
An important thing to remember; when you have the new partition ready, pre-seed the data first. Don't start with one server empty. Pre-seed it from a backup, or copy the files with Robocopy. Remember, DFS-R isn't going to overwrite newer
files with older files.

DFS Best Practice and domain structures
We currently have built a new domain structure for our client which consist of domains in separate forests with the approapriate trusts in place. The domains being:
user, resource, legacy resource and Test.
It is assumed that the resources will be migrated out of the legacy domain to the new resource domain in the medium term.
Given we have circa 650 file shares, which causes problems with logon scripts, I want to present those shares via a DFS. Internally our view is that the DFS should be built in the user forest to reference file shares in the resource domain(s).
Our client, however believes the DFS is a resource, and therfore should be presented in the new resource domain.
What are the pros / cons of each and what would be the Microsoft recommendation and why ?Hi,
As the purpose is to migrate shares to new domain (in new forest), it seems DFS is not required to do this job.
From your description, it seems that DFS is not created yet.
If so, you can simply migrate files to new domain. Then you could export the following key and import to new file server:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares
Note: If folder location is changed, you need to edit the key before importing to new server.
In addition, if DFS is already existing, you could export it, edit configuration files and import to new domain. See:

http://blogs.technet.com/b/askds/archive/2008/01/15/migrating-your-dfs-namespaces-in-three-sorta-easy-steps.aspx
Note: If you need to keep NTFS permissions, firstly you need to create a one-way trust (source domain trusts the target domain) and use ADMT to migrate domain users/groups to new domain so that all NTFS permissions could be recognized.
Note2: To copy files with NTFS permission, you could use Robocopy.

What about Scratch Disk fragmentation?
I edit TIFF image files with lots of layers that range in size from 50MB to 90MB. With only 4GB of RAM, my system relies heavily on scratch disk performance for these large files. I have a non-system internal SATA HDD with an 80GB volume dedicated as a scratch disk.
I have read that it's important the scratch disk be a defragmented volume. I have also heard that Macs defragment files smaller than 20MB automatically, which I don't think helps me much.
My questions are, does Photoshop CS4 delete/remove files on the scratch disk after an edit session ends and PS is closed, and then starts with a "clean slate" when re-opened? Or do all the scratch disk files just pile up in pieces over time that tend to fragment the scratch disk? If so, does the scratch disk need to be re-formatted (erased) regularly? Thanks.Marian Driscoll wrote:
If there is nothing on that 80GB volume (when Photoshop is closed) then there is nothing to worry about. Fragmentation is only an issue if the drive has files on it.
Thanks Chris and Marian.
I have been monitoring my scratch disk in Disk Utility and have noticed that after closing PS, the amount of disk space indicated as being used drops from about 1GB to around 60MB, with the number of files indicated on the disk dropping to around 40. When I erase the volume using D.U., then there are 32 files indicated as being on the volume.
So apparently, there are files being created by both the OS (around 32 files) and also PS (around 8) that remain on the scratch disk after PS is closed. Maybe these PS files are just "place-holder" files, because the amount of space used by these PS files appears to be less than 1MB. Relative to an 80GB volume, this seems rather insignificant.
Nevertheless, I'm now thinking that it may be a good maintenance practice to erase (re-format) my scratch disk once a month or so just to help optimize it. It's easy to do in Disk Utility. -

Rules for defining operations in Work Orders
What is the best practice for defining work order operations for better knowledge retention. How we can distinguish multiple operations in work order?
Our maintenance stuff is defined single operation like replacement of bearing in work order which is of no use for knowledge retention. What measures/guidelines should be taken in this regard?
Regards,
TehsinHi Tehsin
Technically every one has answered correctly, however I would like to add few points
1. I completely agree with Shri Maheswaran that operations shall be created on broad heads & only differentiated basd on diffrent activity type(for different wage grp) or Performing work center or according different broad activity (functional) which has specific relevance.
2. As a best practice we have created standard maintenance practice (SMP) which contains details of activity for say replacement of motor which normally do not changeover period & attach this document to technical object in DMS. Further we have standardised operations using standard text key e.g. Replace motor type xxx, xxkW / Maintain motor type xxx/ Maintain panel etc.
At most we have included the broad sub activities as operations or in long text as per requirement but not how parts because how part will always remains same (untill & unless objct changes or there is any revision of the document). If you want the status of completion of your broad activities as mailestones then also you shall create it as operation or sub operation. If you put it in long text you will not get separate status.

Did any one of you work on RCM? If so, could you explain in brief how this is implemented in SD module
I came across a job position which says RCM knowledge is required.Thanks for your updates.
As no one replied to my query for long time, I did my own research on RCM.
I am posting the notes. It may be useful to someone looking for an opportunity with RCM requirement.
RCM stands for "Reliability Centered Maintenance". It is a formal method to determine the maintenance requirements of an asset in its operating context. It is a proven methodology for developing effective maintenance strategies.
RCM stresses a proactive approach to maintenance. This method attempts to match the best maintenance practice to mitigate a potential failure relative to the importance of preventing that failure. RCM stresses the value of maintaining or preserving of a function as opposed to maintaining an asset.
RCM was first used in airline industry but since then it was used by other industries to
- Improve operational reliability
- Optimize equipment performance
- Make better design and life cycle decisions
- Control risk
RCM is used with SAP - EAM (Enterprise Asset Management)
SAP EAM focuses on the efficient execution of:
- Maintenance Planning & Scheduling
- Maintenance Work
- Spare Parts Management
- Maintenance History and Reporting -
Unusual extended attribute on Library folder
I was looking around in my home folder and noticed that my Library (/Users/xxx/Library) folder has an unusual extended attribute. Have attached an image of the detailed information. Anyone have any idea what this is about? The attribute is 620 bytes long and looks to be some sort of compressed or binary data. The attribute has a weird name "Q3JCEFADN8SD817B1317B7C0707CA" and I've searched on the web for information but no luck.
Any idea on how to track down when or how or by what program this got added to the Library folder? I've looked in my entire user folder and only this Library folder has this particular extended attribute.
Thanks for any ideas or suggestions.
-BobYou've gotten misinformation, so you're confused. Not your fault at all.
The ROOT LEVEL Library is not hidden in 10.7.5 at all. It's right there where it has always been, at the Root Level, i.e. at the same level where your Applications, Systems and Users folders have always been.
That's the Library where your fonts belong, in a sub-folder labeled Fonts.
What is hidden is the User Library, and it is hidden for a very good reason: you have no business messing with that Library. Fonts do not belong there at all. Apple made it hidden precisely because they don't want you to find it. And it has nothing to do with any updates, it has been there since Lion 10.7.0 beta, not available to the general public.
There is of course a way to access it, and no Terminal hokus pokus is involved at at all. It's right under the GO menu in the Finder > Go to Folder…, you just need to know exactly what path to type there to get to the Library.
I won't tell you because you really have no business going there in the first place, especially at your level of knowledge of the Mac OS X.
Adobe help said that with the updates, apple made the library folder invisible to photoshop
Ah, you just happened to talk to a complete, ignorant idiot, of which there are untold numbers manning the outsourced customer service and tech support call centers in India.
Even the hidden User Library is visible to all applications. What you were told is utter nonsense. Apple wanted to keep clueless users out, not applications. Good Grief!

Hi there
Years ago, we were told that it is good maintenance practice to bounce your essbase database server on a regular basis as it clears out any fragmented memory and caching issues. Is this still the case today?. I would like to have our DBA do the same with our essbase servers todayHi ColDFire,
I've not seen real issues with caches not performing as designed. As I mentioned in my earlier post if the cache sizes are set too high or the server has limited memory restarting can be a work-around; however work-around are not typically a solid mechanism for a production application -- the real issue should be addressed rather than starting/stopping. If the concern is only that memory is used and not released then that is really not an issue -- an server application like Essbase allocating memory and releasing it would actually fragment memory which is not good; this is why memory is typically not released by applications which need to use large amounts on a server environment.

What disk and when do I repair permissions?
Hi I'm wondering how and when to "repair permissions" - Do I select the icon in disk utility marked 111.8 GB Samsung HM120JC or the icon beneath it marked and named as my hard drive? Does it matter? And how often/when should I do this?
Thanks much
KBHi, Kent. It doesn't really matter whether you select the hard drive mechanism (the top line that you've named in your post) or the volume that appears as the startup drive on your desktop — either way, the permissions on that volume will be repaired. If your hard drive is partitioned into two or more volumes, and you select the drive mechanism, permissions will be repaired on each volume that contains an OS X installation. (Permissions can only be repaired on a volume that contains OS X; a partition that doesn't have OS X installed on it can't have its permissions repaired.)
You should always repair permissions after any software update, upgrade or installation that involves Apple's Installer application (Installer.app). Most knowledgeable folks here also recommend doing so before every such installation, upgrade or update, to prevent a damaged or corrupt permission from interfering with the Installer's business and thereby fouling up whatever's being installed.
Repairing permissions is not a cure-all, and though some people consider it a routine maintenance practice, others emphatically don't. I think of it as a totally harmless, free, quick, easy procedure that sometimes solves minor problems, and I probably do it more often than is really productive: every two or three weeks, even if I haven't installed anything lately or had any problems. But I always do it before and after every Apple software installation, even ones that are installed through the Software Update utility — and that means I never allow SU to install more than one thing at a time, specifically so I can repair permissions between installations. -
Apple Updates Make Library Folder Invisible to Photoshop
Can anyone tell me how to make my library folder visible to Photoshop CS5.1 Extended? My fonts have been missing ever since I ran an update the os x 10.75 update on my mac. Adobe help said that with the updates, apple made the library folder invisible to photoshop. i tried their suggestion to go to terminal and type a command to make the library folder permanently visible, but that didn't solve the problem.

What is best practice for using Maintenance Optimizer to download SPS + EhP
SAP indicates in note 1095233 and many other documents that the best practice is to implement an EhP along with an SP Stack in the same queue. Furthermore, the only way to download the components of an EhP is via Maintenance Optimizer. However, in step 2 (Calculate download files automatically) you must choose either Maintenance (SPS) or Enhancement Package Installation (EhP); there is no way to tell Maintenance Optimizer that you want to download both SPS and EhP.
In developing the process for my team I circumvented the problem by saying to select Maintenance first to get the SPS into the Download Basket and follow that with selecting Enhancement Package Installation to get the EhP into the Download Basket. The plan would be to include all the downloads in the SPAM/SAINT queue with the expectation that SPAM/SAINT will be able to determine what must be included.
I'm wondering now whether that is a legitimate way to approach this and I am hoping others will share their process.
Thanks,
Terry McCann
Monsanto Company
St. Louis, MOActually, I don't believe you will get the entire SP Stack for ERP 6, you only get those pieces of the stack that are required for the Technical Usages you select for the EhP. I'm basing that on my observation that you get a different subset of the files making up the stack depending upon your TU selection. Also, note 1095233 specifically states:
If now the corrections included in the enhancement package 3 correspond to ERP 6.0 SP level 11, SAP recommends to update also the parts of your system to SP level 11 which you do not want to update to enhancement package 3 to achieve a consistent correction level in all parts of your application: SAP recommends to update all software components to the correction status corresponding to SAP ERP 6.0 Support Package Stack 11 with the installation of SAP enhancement package 3 for SAP ERP 6.0.

Best practices in Queue table maintenance
Hi Fellow AQ Users,
I am looking to hear from the community about best practices in queue table maintenance.
I have been mining through metalink about various Oracle recommendations and putting
together a set of recommendations as a starting point for my DBAs.
I am looking to answer questions like these --
How often (in relation to messaging load) would you coalesce and rebuild the indexes?
How often would you rebuild the table itself to get rid of the high water mark issues ?
and what procedure would you use to do that?
Would really love to learn from your experiences in this area. We are using 9.2.0.7
64 bit DB and have plans to go to 10g over the next year. So, I am looking at 9i related
stuff and then 10g.
Thanks
VijayHello,
In general you coalesce once per day ideally during a quiet time to avoid ORA-54 errors as per <Note:271855.1>. Some customers do it more often than that but once per day is a good starting point.
In terms of shrinking the queue tables you can use the procedure in <Note:304522.1> with a null 3rd parameter. This is an offline procedure so you could only run it during a maintenance window. In 10.2 onwards you can dynamically shrink the queue table and IOTS. Again it depends on exactly what you are doing with your queue tables how often you might need to do this.
Thanks

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,
TroyIt 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.
