Oracle Best Practices Discussion Pros/Cons of using Synonyms

Please share your experience given the Pros/Cons of Developing Enterprise Database Applications using public and private Synonyms.
My recommendation to developers on my team is to avoid using Public Synonyms in their code and instead Fully Qualify the database object by schema owner.
Pros: When you drop a schema, you do not drop the public synonyms that they created. Therefore if you have to use synonym, make it private and not public.
Please share your experience!

Well I rarely use public synonyms and that only case of db links. For example, I have a scenario, in which I have hooked up a MS SQLSERVER database with Oracle database through Heterogenous Services. I am accessing the SQLSERVER table in real time, through HS, in Oracle in real time, and then from this Oracle environment I have created db links to many other interested databases. In those interested database, I have created public synonyms over those dblinks.
It's so transparent for the interested databases. But I have documented this whole configuration in great detail for any upcoming DBA, just in case I leave, or expire or anything. Sounds interesting - this might be worth 'cleaning' and publishing to OTN's Articles.

Best practice for updating SL to 10.6.8

recently purchased a 2009 iMac with Snow Leopard upgrade installed OS 10.6
Looks as though there are two updates; should I install both or can I install the last/latest. Appreciate being directed to best practices discussions.
FYI I will want to install Rosetta for older applications, CS3 & CS4, that I need for old client files. Thanks.
Ali

Buy one. Anything you want to keep shouldn't be on only one drive; problems may occur at any time, and are particularly likely to occur during an OS update or upgrade.

ASR9000 best practices

Hi Sir/Madam,
Is there any CISCO ASR 9000 best practices document for installation and configuration?

What is the best practice for QOS in an MDS 9000 environment for the FCIP traffic?

Our storage group is implementing an MDS 9000 FCIP environment. The person configuring the Nexus equipment is asking what QOS markings and bandwidth requirements should be used for the FCIP traffic.
Is there a document that describes the QOS recommendations for MDS FCIP?

Hello
You can change the DB isolation level to Read uncommitted

or use WITH (NOLOCK)
I do use NOLOCK option for the dirty reads to avoid locks on the tables

Best Practices for multi-switch MDS 9124 Impelementations

Hi,
I was wondering if anyone had any links to best-practices guides, or any experience, building mutli-swtich fabrics with the Cisco MDS 9124 or similar (small) switches? I've read most of the FibreChannel books out there and they all seem pretty heavy on theory and FibreChannel protocol operations but lack when it comes to real-world deployment scenarios. Something akin to the Case Studies sections a lot of the CCIE literature has, but anything would be appreciated.

Hi Meridith
www.Whitepapers.zdnet.com has links to good reading. It has links to items like:
http://www.vmware.com/pdf/esx_san_cfg_technote.pdf is probably a typical SAN environment these days. It's basic and just put your 9124's in where the switches are.
http://www.sun.com/bigadmin/features/hub_articles/san_fundamentals.pdf is for bigger SANs such as DR, etc.
Things to consider with 9124's are:
They can break so keep a good current backup on a tftp/ftp/scp server.
Consider that if you have all the ports used, the two 8 port licences are not going to work on a replacement switch as they are bound to your hostid. The vendor that sold the switch should be able to get replacements quickly but you will lose time with them.
Know exactly what the snmpserver command does as if you have your 9124 replaced and you load your backup config and you use Fabric Manager, it won't be able to manage the 9124 unless you change the admin password with snmpserver.
9124/9134's don't have enough Buffer Credits to expand beyond about 10 km.
Any ISL's used between switches should always be at least two and use Port Channels where possible.
The 9124 or 9124e or 9134 are great value based switches. I keep a spare for training and emergencies. We use them in a core/edge solution and I am very satisfied with them. I have only had one failure with Cisco switches in the last 5 years and it was a 9140 that sat around for far too long doing nothing. The spare meant we were up and running in 30 minutes from the time we noticed the failure and got to the data centre. As there were two paths, no one actually noticed anything. My management system alerted me.
Remember to make absolutely sure that any servers attached to the SAN have multipathing software. The storage array vendors (HDS, EMC, etc) can sell you the software such as HDLM or Powerpath. You can use an independent solution such as Veritas DMP. Just don't forget to use it.
Follow the guidelines in the two documents and get some training as the MDS training is very good indeed. 5 days training and you will be confident about what to do in any sized SAN including Brocade and McData.
A small SAN is just as satisfying as a large one. If in doubt, get a consultant to tell you what to do.
Is that what you was after? I hope it was not too simple.

Best Practices for MDS Monitoring

We are deploying Solarwinds and would like some tips on what would be useful to monitor on MDS switches. Of course, the normal port utilization, cpu, interface counters are already set up, but thought I would check to see if anyone has any suggestions on any other OID's I should look into.
Thanks!

Hi Mike,
Did you try the following link ?

Is there a website or PDF somewhere which discusses best practices for producing a children's picture book? I am mostly interested in requirements for good image format, resolution, etc.

Is there a website or PDF somewhere which discusses best practices for producing a children's picture book? I am mostly interested in requirements for good image format, resolution, etc.

There may be a few links in Apple Support, regarding articles about how to use iBooks Author
and iBooks Store, etc; these would be separated into two general categories by device used.
Since there is an iOS and an OS X version of each, you may have to look to see what Apple
Support says about the one you are interested in; and how far their database goes toward an
answer to your question. Otherwise, a general search engine approach may be necessary.
Not sure if anything along the lines of what you seek would be available in an App.
References to iBooks Author and iBooks Store, etc appear within these two categories in Support:
For Mac OS X:
http://www.apple.com/support/mac-apps/
For iOS:
http://www.apple.com/support/ios/
Appears a community host moved your earlier post into one of the iBooks Author or Store sections
after I'd replied to what otherwise may be a similar post. Not sure if the links to the Discussions area
of iBooks you are interested in, have similar questions or answers by others who'd visited previously.

In my reply to your earlier thread, prior to it being moved, those links to sections of iBooks Author, etc

Sorry to not be of much help in this matter.
Good luck & happy computing!

General Discussion - Best practice to manage Process order

Hi Experts,
Which is the best practice to manage process orders ?
1. Quantity Change - I can make quantity adjustment in R3 and APO.
2. Source Change - I can make a version change from order header . Also i can make a source change in APO by selecting a different PPM. Which is the best option.
3. Re Read Master Data - Best practice to read master data is from R3 or APO ?
I feel for all the above scenarios process ordes should always managed in R3. But still wondering why we have the same flexibility in APO too ?

Hello,
we are just migrating from 4.6c to ECC 6.0 and I have a couple of workflows to adopt.
For background steps I defined in the corresponding BOR methods an exception to be fired when no result is available (e.g. no mail address available). Normally, I defined them as temporary errors.
I activated in the WI outcome section the line for this exception and so the workflow processed this branch when the exception appeared. It worked fine.
Now, in ECC 6.0, the same workflow get stuck in the WI. The exception is fired (I can see it in the log as "Error message"), but the WI is still in status "in process". It doesn't continue with the error outcome branch.
Is this a new logic in ECC 6.0? Do you have any idea what to do? I used this logic some dozent times in different methods and workflows and it gives me a headache if I have to change everything ...
Thank you!
Best regards,
Thomas

FC port channels between MDS and UCS FI best practice?

Hi,
We would like to create FC port channels between our UCS FI's and MDS9250 switches.
At the moment we have 2 separate 8Gbps links to the FI's.
Are there any disadvantages or reasons to NOT do this?
Is it a best practice?
Thanks.

As Walter said, having port-channels is best practice. Here is a little more information on why.
Let's take your example of two 8Gbps links, not in a port-channel ( and no static pinning ) for Fibre Channel connectivity:
Hosts on the UCS get automatically assigned ( pinned ) to the individual uplinks in a round-robin fashion.
(1)If you have some hosts that are transferring a lot of data, to and from storage, these hosts can end up pinned to the same uplink and could hurt their performance.
In a port-channel, the hosts are pinned to the port-channel and not individual links.
(2)Since hosts are assigned to an individual link, if that link goes down, the hosts now have to log back into the fabric over the existing working link. Now you would have all hosts sharing a single link. The hosts will not get re-pinned to a link until they leave and rejoin the fabric. To get them load balanced again would require taking them out of the fabric and adding them back, again via log out, power off, reload, etc...
If the links are in a port-channel, the loss of one link will reduce the bandwidth of course, but when the link is restored, no hosts have to be logged out to regain the bandwidth.
Best regards,
Jim

IronPort best practices and configuration guide

Hi there,
I manage a Cisco IronPort ESA appliance for my organisation and made a quick blog post last night about things I thought should be a best practice for a new ESA appliance.
The reason I wrote this is because some of these things are not configured from the start or are configured poorly by default.
Take a look and let me know what you think - I plan to make a part 2 because there are some things I did not have time to go through and it was quite long already!
Remember that your environment will be different from mine so you should understand the things I say before blindly implementing them!

First of all, I think your question is related to the WebCenter (Framework) as such, not just OUCSS.
As for JDev. vs. run-time, this question is well discussed in Yannick Ongena's tutorial: http://www.yonaweb.be/webcenter_tutorial/part1_configure_webcenter_portal_application
"Let me first talk a bit about the architecture of WebCenter and the runtime customizations. ADF (and WebCenter) has an additional component since 11g called the MDS (MetaDataServices). The MDS is a repository that stores all the customizations. The page we just created at runtime is not stored in the project folder of JDeveloper but is instead stored in the MDS."
I guess the answer when to use which methods depends on the situation what page you want to create.
I am surprised, however, that you state that
Pages created in JDeveloper are not searchable online. It is possible to link it to a Navigation Model but the path needs to be manually entered.Could you elaborate on your use case?
As for navigation models, you can check another tutorial: http://docs.oracle.com/cd/E21764_01/webcenter.1111/e10148/jpsdg_navigation.htm#BABJHFCE
Maybe, what your are looking for is the way how to create a navigation model according to your needs?

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.
From the terms of use of this forum:
"Keep within the Law
No material may be submitted that is intended to promote or commit an illegal act.
Do not submit software or descriptions of processes that break or otherwise ‘work around’ digital rights management software or hardware. This includes conversations about ‘ripping’ DVDs or working around FairPlay software used on the iTunes Store."

Best Practice on using and refreshing the Data Provider

I have a �users� page, that lists all the users in a table - lets call it master page. One can click on the first column to of the master page and it takes them to the �detail� page, where one can view and update the user detail.
Master and detail use two different data providers based on two different CachedRowSets.
Master CachedRowSet (Session scope): SELECT * FROM UsersDetail CachedRowSet (Session scope): SELECT * FROM Users WHERE User_ID=?I want the master to be updated whenever the detail page is updated. There are various options to choose from:
1. I could call masterDataProvider.refresh() after I call the detailDataProvider.commitChanges() - which is called on the save button on the detail page. The problem with this approach is that the master page will not be refreshed across all user sessions, but only for the one saving the detail page.
2. I could call masterDataProvider.refresh() on the preRender() event of the master page. The problem with this approach is that the refresh() will be called every single time someone views the master page. Further more, if someone goes to next page (using the built in pagination on the table on master page) and clicks on a user to view its detail and then close the detail page, it does not keep track of the pagination (what page the user was when he/she clicked on a record to view its detail).
I can find some work around to resolve this problem, but I think this should be a fairly common usage (two page CRUD with master-detail). If we can discuss and document some best practices of doing this, it will help all the developers.
Discussion:
1.     What is the best practice on setting the scope of the Data Providers and CahcedRowSet. I noticed that in the tutorial examples, they used page/request scope for Data Provider but session scope for the associated CachedRowSet.
2.     What is the best practice to refresh the master data provider when a record/row is updated in the detail page?
3.     How to keep track of pagination, (what page the user was when he/she clicked on the first column in the master page table), so that upon updating the detail page, we cab provide user with a �Close� button, to take them back to whaterver page number he/she was.
Thanks

Thanks. I think this is a useful information for all. Do we even need two data providers and associated row sets? Can't we just use TableRowDataProvider, like this:
TableRowDataProvider rowData=(TableRowDataProvider)getBean("currentRow");If so, I am trying to figure out how to pass this from master to detail page. Essentially the detail page uses a a row from master data provider. Then I need user to be able to change the detail (row) and save changes (in table). This is a fairly common issue in most data driven web apps. I need to design it right, vs just coding.

Best Practices for Using Photoshop (and Computing in General)

I've been seeing some threads that lead me to realize that not everyone knows the best practices for doing Photoshop on a computer, and in doing conscientious computing in general. I thought it might be a good idea for those of us with some exprience to contribute and discuss best practices for making the Photoshop and computing experience more reliable and enjoyable.
It'd be great if everyone would contribute their ideas, and especially their personal experience.
Here are some of my thoughts on data integrity (this shouldn't be the only subject of this thread):
Consider paying more for good hardware. Computers have almost become commodities, and price shopping abounds, but there are some areas where spending a few dollars more can be beneficial. For example, the difference in price between a top-of-the-line high performance enterprise class hard drive and the cheapest model around with, say, a 1 TB capacity is less than a hundred bucks! Disk drives do fail! They're not all created equal. What would it cost you in aggravation and time to lose your data? Imagine it happening at the worst possible time, because that's exactly when failures occur.
Use an Uninterruptable Power Supply (UPS). Unexpected power outages are TERRIBLE for both computer software and hardware. Lost files and burned out hardware are a possibility. A UPS that will power the computer and monitor can be found at the local high tech store and doesn't cost much. The modern ones will even communicate with the computer via USB to perform an orderly shutdown if the power failure goes on too long for the batteries to keep going. Again, how much is it worth to you to have a computer outage and loss of data?
Work locally, copy files elsewhere. Photoshop likes to be run on files on the local hard drive(s). If you are working in an environment where you have networking, rather than opening a file right off the network, then saving it back there, consider copying the file to your local hard drive then working on it there. This way an unexpected network outage or error won't cause you to lose work.
Never save over your original files. You may have a library of original images you have captured with your camera or created. Sometimes these are in formats that can be re-saved. If you're going to work on one of those files (e.g., to prepare it for some use, such as printing), and it's a file type that can be overwritten (e.g., JPEG), as soon as you open the file save the document in another location, e.g., in Photoshop .psd format.
Save your master files in several places. While you are working in Photoshop, especially if you've done a lot of work on one document, remember to save your work regularly, and you may want to save it in several different places (or copy the file after you have saved it to a backup folder, or save it in a version management system). Things can go wrong and it's nice to be able to go back to a prior saved version without losing too much work.
Make Backups. Back up your computer files, including your Photoshop work, ideally to external media. Windows now ships with a quite good backup system, and external USB drives with surprisingly high capacity (e.g., Western Digital MyBook) are very inexpensive. The external drives aren't that fast, but a backup you've set up to run late at night can finish by morning, and if/when you have a failure or loss of data. And if you're really concerned with backup integrity, you can unplug an external drive and take it to another location.
This stuff is kind of "motherhood and apple pie" but it's worth getting the word out I think.
Your ideas?

APC Back-UPS XS 1300. $169.99 at Best Buy.
Our power outages here are usually only a few seconds; this should give my server about 20 or 25 minutes run-time.
I'm setting up the PowerChute software now to shut down the computer when 5 minutes of power is left. The load with the monitor sleeping is 171 watts.
This has surge protection and other nice features as well.

Best practices for office 365 SHARED CALENDAR for whole school / organization

hi
we need guidance on best practice for setting up SHARED CALENDAR on Office365 exchange server for entire organization (school)of150 staff.
Requirements
+ all staff should have read only / reviewer permissions on calendar
+handful staff should have editor permissions on calendar
+ the calendar should synchronise custom categories and colors
Current Solution
at the moment we have found that a shared mailbox is the best solution because;
- allusers can add the shared mailbox on outlook 2010as additional mailbox as readonly
- all the categories & colors for the calendarare automatically synchronised because the color categories are stored within this mailbox.
- you can edit calendar permissions in outlook to allow some users as "editor" of the calendar.Problem with Current Solution
the problem however is that the users also need to access this...
This topic first appeared in the Spiceworks Community

Hi Aleksei,
I think Inactive mailboxes in Exchange Online is the feature that you want. This feature makes it possible for you to preserve (store and archive) the contents of deleted mailboxes indefinitely.
A mailbox becomes inactive when an In-Place Hold or a
Litigation Hold is placed on the mailbox before the corresponding Office 365 user account is deleted.
But I'm afraid that it might be impossible to "easily share certain folders or even whole mailbox with people in the company". As can been seen from below articles, this only allows administrators, compliance officers, or records managers
to use the In-Place eDiscovery feature in Exchange Online to access and search the contents of an inactive mailbox:
http://technet.microsoft.com/en-us/library/dn144876(v=exchg.150).aspx
http://blogs.technet.com/b/exchange/archive/2013/03/21/preserve-mailbox-data-for-ediscovery-using-inactive-mailboxes-in-exchange-online.aspx
Anyway, this is the forum to discuss questions and feedback for Microsoft Office client. For more details about your question, I would suggest you post in the dedicated forum of
Exchange Online, where you can get more experienced responses:
https://social.technet.microsoft.com/Forums/msonline/en-US/home?forum=onlineservicesexchange
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
