Best Practice for Retiring Superseded or Expired Updates

If you want to clear out superseded or expired updates, do you delete them from your update package, the deployment package, or both? Or is there another best practice for this?
Thanks,
Bryan

Hi Torsten, im reading this article because im actualy planing to solve some kind of the the same problem.
I create Software Update Groups with monthly patches, and then i will deploy this to certain Client Collections.
If there becomes a single Patch, the Status, "expired", out of the Software Update Group, what would be the effect for the whole Software Update Group wich still have an active deployment?
Thanks for your sugestion.

Best Practice for Expired updates cleanup in SCCM 2012 SP1 R2

Hello,
I am looking for assistance in finding a best practice method for dealing with expired updates in SCCM SP1 R2. I have read a blog post: http://blogs.technet.com/b/configmgrteam/archive/2012/04/12/software-update-content-cleanup-in-system-center-2012-configuration-manager.aspx
I have been led to believe there may be a better method, or a more up to date best practice process in dealing with expired updates.
On one side I was hoping to keep a software update group intact, to have a history of what was deployed, but also wanting to keep things clean and avoid issues down the road as i used to in 2007 with expired updates.
Any assistance would be greatly appreciated!
Thanks,
Sean

The best idea is still to remove expired updates from software update groups. The process describes in that post is still how it works. That also means that if you don't remove the expired updates from your software update groups the expired updates will
still show...
To automatically remove the expired updates from a software update group, have a look at this script:

Best Practice for Updating children UIComponents in a Container?

What is the best practice for updating children UIComponents in response to a Container being changed? For instance, when a Canvas is resized, I would like to update all the children UIComponents height and width so the content scales properly.
Right now I am trying to loop over the children calling InvalidateProperties, InvalidateSize, and InvalidateDisplayList on each. I know some of the Containers such as VBox and HBox have layout managers, is there a way to leverage something like that?
Thanks.

you would only do that if it makes your job easier. generally speaking, it would not.
when trying to sync sound and animation i think most authors find it easiest to use graphic symbols because you can see their animation when scrubbing the main timeline. with movieclips you only see their animation when testing.
however, if you're going to use actionscript to control some of your symbols, those symbols should be movieclips.

Best practice for auto update flex web applications

Hi all
is there a best practice for auto update flex web applications, much in the same way AIR applications have an auto update mechanism?
can you please point me to the right direction?
cheers
Yariv

Hey drkstr
I'm talking about a more complex mechanism that can handle updates to modules being loaded into the application ect...
I can always query the server for the verion and prevent loading from cach when a module needs to be updated
but I was hoping for something easy like the AIR auto update feature

SQL 2008 R2 Best Practices for Updating Statistics for a 1.5 TB VLDB

We currently have a ~1.5 TB VLDB (SQL 2008 R2) that services both OLTP and DSS workloads pretty much on a 24x7x365 basis. For many years we have been updating statistics (full scan- 100% sample size) for this VLDB once a week on the weekend, which
is currently taking up to 30 hours to complete.
Somewhat recently we have been experiencing intermitent issues while statistics are being updated, which I doubt is just a coincidence. I'd like to understand exactly why the process of updating statistics can cause these issues (timeouts/errors). My theory
is that the optimizer is forced to choose an inferior execution plan while the needed statistics are in "limbo" (stuck between the "old" and the "new"), but that is again just a theory. I'm somewhat surprised that the "old" statistics couldn't continue to
get used while the new/current statistics are being generated (like the process for rebuilding indexes online), but I don't know all the facts behind this mechanism yet so that may not even apply here.
I understand that we have the option of reducing the sample percentage/size for updating statistics, which is currently set at 100% (full scan). Reducing the sample percentage/size for updating statistics will reduce the total processing time, but
it's also my understanding that doing so will leave the optimizer with less than optimal statistics for choosing the best execution plans. This seems to be a classic case of not being able to have one’s cake and eat it too.
So in a nutshell I'm looking to fully understand why the process of updating statistics can cause access issues and I'm also looking for best practices in general for updating statistics of such a VLDB. Thanks in advance.

I'm with you. Yikes is exactly right with regard to suspending all index optimizations for so long. I'll probably start a separate forum thread about that in the near future, but for now lets stick to the best practices for updating statistics.
I'm a little disappointed that multiple people haven't already chimed in about this and offered up some viable solutions. Like I said previously, I can't be the first person in need of such a thing. This database has 552 tables with a whole lot more statistics
objects than that associated with those tables. The metadata has to be there for determining which statistics objects can go (not utilized much if at all so delete them- also produce an actual script to delete the useless ones identified) and what
the proper sample percentage/size should be for updating the remaining, utilized statistics (again, also produce a script that can be used for executing the appropriate update statistics commands for each table based on cardinality).
The above solution would be much more ideal IMO than just issuing a single update statistics command that samples the same percentage/size for every table (e.g. 10%). That's what we're doing today at 100% (full scan).
Come on SQL Server Community. Show me some love :)

Best practices for updating agents

We're getting ready to do our first system-wide update of agents to fix a critical bug. Our summer vacation is just ending, and teachers and students will be coming back very soon and turning on our Windows 7 computers for the first time in many weeks, although they won't all be turned on the same day. When they are turned on they will be attempting to get various updates, in particular Windows updates, but also Flash Player and Adobe Reader. I need to update the agents as quickly as possible, but I'm concerned about the possibility of the agent update conflicting with another update, especially Windows updates. Isn't it possible that Windows Update could restart a computer while the agent update is happening (or the other way around), leaving the machine in an unstable or unusable state? What are the best practices for dealing with this? I considered the possibility of deploying the agent to a dynamic workstation group whose members all have a certain file or files that indicate that they have already received the latest Windows updates. However, I can't see how to create a dynamic group based on such criteria.
So far I have only updated a few devices at a time using "Deploy System Updates to Selected Devices in the Management Zone". When those updates are done I cancel that deployment because that's the only option I can find that does anything. If you can offer general advice for a better strategy of updating agents I'd appreciate that. Specifically, how would you push an agent update to several hundred computers that will be turned on sometime over the next two weeks?
Thanks very much.

To be honest, you have to work around your other deploys, etc. The ZCM agent isn't "aware" of other deploys going on. For example, ZPM doesn't care that you're doing Bundles at the same time (you'll get errors in the logs about the fact that only one MSI can run at a time, for example). ZPM usually recovers and picks up where it left off.
Bundles on the other hand, with System Update, are not so forgiving. Especially if you have the agents prior to 11.2.4 MU1 (cache corruption errors).
We usually:
a) Halt all software rollouts/patching as best we can
b) Our software deploys (bundles) are on event: user login Typically the system update is on Device Refresh, OR scheduled time, and are device associated.
IF possible, I'd suggest that you use WOL, system update and voila.
Or, if no WOL available, then tell your users to leave their pc turned on (doesn't have to be logged in), on X night, and setup your system updates for that night, with the auto-reboot enabled. That worked well
But otherwise the 3 components of ZCM (Bundles, ZPM, System Update) don't know/care about each other, AFAIK.

IOS Update Best Practices for Business Devices

We're trying to figure out some best practices for doing iOS software updates to business devices. Our devices are scattered across 24 hospitals and parts of two states. Going forward there might be hundreds of iOS devices at each facility. Apple has tools for doing this in a smaller setting with a limited network, but to my knowledge, nothing (yet) for a larger implementation. I know configurator can be used to do iOS updates. I found this online:
https://www.youtube.com/watch?v=6QPbZG3e-Uc
I'm thinking the approach to take for the time being would be to have a mobile sync station setup with configurator for use at each facility. The station would be moved throughout the facility to perform updates to the various devices. Thought I'd see if anyone has tried this approach, or has any other ideas for dealing with device software updates. Thanks in advance.

Hi Bonesaw1962,
We've had our staff and students run iOS updates OTA via Settings -> Software Update. In the past, we put a DNS block on Apple's update servers to prevent users from updating iOS (like last fall when iOS 7 was first released). By blocking mesu.apple com, the iPads weren't able to check for or install any iOS software updates. We waited until iOS 7.0.3 was released before we removed the block to mesu.apple.com at which point we told users if they wanted to update to iOS 7 they could do so OTA. We used our MDM to run reports periodically to see how many people updated to iOS 7 and how many stayed on iOS 6. As time went on, just about everyone updated on their own.
If you go this route (depending on the number of devices you have), you may want to take a look at Caching Server 2 to help with the network load https://www.apple.com/osx/server/features/#caching-server . From Apple's website, "When a user on your network downloads new software from Apple, a copy is automatically stored on your server. So the next time other users on your network update or download that same software, they actually access it from inside the network."
I wish there was a way for MDMs to manage iOS updates, but unfortunately Apple hasn't made this feature available to MDM providers. I've given this feedback to our Apple SE, but haven't heard if it is being considered or not. Keeping fingers crossed.
Hope this helps. Let us know what you decide on and keep us posted on the progress. Good luck!!

Best practice for the Update of SAP GRC CC Rule Set

Hi GRC experts,
We have in a CC production system a SoD matrix that we would like to modified extensively. Basically by activating many permissions.
Which is a best practice for accomplish our goal?
Many thanks in advance. Best regards,
Imanol

Hi Simon and Amir
My name is Connie and I work at Accenture GRC practice (and a colleague of Imanolu2019s). I have been reading this thread and I would like to ask you a question that is related to this topic. We have a case where a Global Rule Set u201CLogic Systemu201D and we may also require to create a Specific Rule Set. Is there a document (from SAP or from best practices) that indicate the potential impact (regarding risk analysis, system performance, process execution time, etc) caused by implementing both type of rule sets in a production environment? Are there any special considerations to be aware? Have you ever implemented this type of scenario?
I would really appreciate your help and if you could point me to specific documentation could be of great assistance. Thanks in advance and best regards,
Connie

Best practice for managing a Windows 7 deployment with both 32-bit and 64-bit?

What is the best practice for creating and organizing deployment shares in MDT for a Windows 7 deployment that has mostly 32-bit computers, but a few 64-bit computers as well? Is it better to create a single deployment share for Windows 7 and include both
versions, or is it better to create two separate deployment shares? And what about 32-bit and 64-bit versions of applications?
I'm currently leaning towards creating two separate deployment shares, just so that I don't have to keep typing (x86) and (x64) for every application I import, as well as making it easier when choosing applications in the Lite Touch installation. But I know
each deployment share has the option to create both an x86 and x64 boot image, so that's why I am confused.

Supporting two task sequences is way easier than supporting two shares. Two shares means two boot media, or maintaining a method of directing the user to one or the other. Everything needs to be imported or configured twice. Not to mention doubling storage
space. MDT is designed to have multiple task sequences, why wouldn't you use them?
Supporting multiple task sequences can be a pain, but not bad once you get a system. Supporting app installs intelligently is a large part of that. We have one folder per app install, with a wrapper vbscript that handles OS detection. If there are separate
binaries, they are placed in x86 and x64 subfolders. Everything runs from one folder via the same command, "cscript install.vbs". So, import once, assign once, and forget it. Its the same install package we use for Altiris, and we'll be using a Powershell
version of it when we fully migrate to SCCM.
Others handle x86 and x64 apps separately, and use the MDT app details to select what platform the app is meant for. I've done that, but we have a template for the vbscript wrapper and its a standard process, I believe its easier. YMMV.
Once you get your apps into MDT, create bundles. Core build bundle, core deploy bundle, Laptop deploy bundle, etcetera. Now you don't have to assign twenty apps to both task sequences, just one bundle. When you replace one app in the bundle, all TS'es are
updated automatically. Its kind of the same mentality as active directory. Users, groups and resources = apps, bundles and task sequences.
If you have separate build and deploy shares in your lab, great. If not, separate your apps into build and deploy folders in your lab MDT share. Use a selection profile to upload only your deploy side to production. In fact I separate everything (except
drivers) into Build and deploy folders on my lab server. Don't mix build and deploy, and don't mix Lab/QA and production. I also keep a "Retired" folder. When I replace an app, TS, OS, etcetera, I move it to the retired folder and append "RETIRED - " to the
front of it so I can instantly spot it if it happens to show up somewhere it shouldn't.
To me, the biggest "weakness" of MDT is its flexibility. There's literally a dozen different ways to do everything, and there's no fences to keep you on the path. If you don't create some sort of organization for yourself, its very easy to get lost as things
get complicated. Tossing everything into one giant bucket will have you pulling your hair out.

Best Practices For Household IOS's/Apple IDs

Greetings:
I've been searching support for best practices for sharing primarily apps, music and video among multple iOS's/Apple IDs. If there is a specific article please point me to it.
Here is my situation:
We currently have 3 iPads (2-kids, 1-dad) in the household and one iTunes account on a win computer. I previously had all iPads on single Apple ID/credit card and controlled the kids' downloads thru the Apple ID password that I kept secret. As the kids have grown older, I found myself constantly entering my password as the kids increased there interest in music/apps/video. I like this approach because all content was shared...I dislike because I was constantly asked to input password for all downloads.
So, I recently set up an individual account for them with the allowance feature at iTunes that allows them to download content on their own (I set restrictions on their iPads). Now I have 3 Apple IDs under one household.
My questions:
With the 3 Apple IDs, what is the best way to share apps,music, videos among myself and the kids? Is it multiple accounts on the computer and some sort of sharing?
Thanks in advance...

Basic Strategy / Best Practices for System Monitoring with Solution Manager

I am very new to SAP and the Basis group at my company. I will be working on a project to identify the best practices of System and Service level monitoring using Solution Manager. I have read a good amount about SAP Solution Manager and the concept of monitoring but need to begin mapping out a monitoring strategy.
We currently utilize the RZ20 transaction and basic CCMS monitors such as watching for update errors, availability, short dumps, etc.. What else should be monitored in order to proactively find possible issues. Are there any best practices you all have found when implimenting Monitoring for new solutions added to the SAP landscape.... what are common things we would want to monitor over say ERP, CRM, SRM, etc?
Thanks in advance for any comments or suggestions!

Hi Mike,
Did you try the following link ?
If not, it may be useful to some extent:
http://service.sap.com/bestpractices
---> Cross-Industry Packages ---> Best Practices for Solution Management
You have quite a few documents there - those on BPM may also cover Solution Monitoring aspects.
Best regards,

Best practices for setting up projects

We recently adopted using Captivate for our WBT modules.
As a former Flash and Director user, I can say it’s
fast and does some great things. Doesn’t play so nice with
others on different occasions, but I’m learning. This forum
has been a great source for search and read on specific topics.
I’m trying to understand best practices for using this
product. We’ve had some problems with file size and
incorporating audio and video into our projects. Fortunately, the
forum has helped a lot with that. What I haven’t found a lot
of information on is good or better ways to set up individual
files, use multiple files and publish projects. We’ve decided
to go the route of putting standalones on our Intranet. My gut says
yuck, but for our situation I have yet to find a better way.
My question for discussion, then is: what are some best
practices for setting up individual files, using multiple files and
publishing projects? Any references or input on this would be
appreciated.

Hi,
Here are some of my suggestions:
1) Set up a style guide for all your standard slides. Eg.
Title slide, Index slide, chapter slide, end slide, screen capture,
non-screen capture, quizzes etc. This makes life a lot easier.
2) Create your own buttons and captions. The standard ones
are pretty ordinary, and it's hard to get a slick looking style
happening with the standard captions. They are pretty easy to
create (search for add print button to learn how to create
buttons). There should instructions on how to customise captions
somewhere on this forum. Customising means that you can also use
words, symbols, colours unique to your organisation.
3) Google elearning providers. Most use captivate and will
allow you to open samples or temporarily view selected modules.
This will give you great insight on what not to do and some good
ideas on what works well.
4) Timings: Using the above research, I got others to
complete the sample modules to get a feel for timings. The results
were clear, 10 mins good, 15 mins okay, 20 mins kind of okay, 30
mins bad, bad, bad. It's truly better to have a learner complete
2-3 short modules in 30 mins than one big monster. The other
benefit is that shorter files equal smaller size.
5) Narration: It's best to narrate each slide individually
(particularly for screen capture slides). You are more likely to
get it right on the first take, it's easier to edit and you don't
have to re-record the whole thing if you need to update it in
future. To get a slicker effect, use at least two voices: one male,
one female and use slightly different accents.
6) Screen capture slides: If you are recording filling out
long window based databse pages where the compulsory fields are
marked (eg. with a red asterisk) - you don't need to show how to
fill out every field. It's much easier for the learner (and you) to
show how to fill out the first few fields, then fade the screen
capture out, fade the end of the form in with the instructions on
what to do next. This will reduce your file size. In one of my
forms, this meant the removal of about 18 slides!
7) Auto captions: they are verbose (eg. 'Click on Print
Button' instead of 'Click Print'; 'Select the Print Preview item'
instead of 'Select Print Preview'). You have to edit them.
8) PC training syntax: Buttons and hyperlinks should normally
be 'click'; selections from drop down boxes or file lists are
normally 'select': Captivate sometimes mixes them up. Instructions
should always be written in the correct order: eg. Good: Click
'File', Select 'Print Preview'; Bad: Select 'Print Preview' from
the 'File Menu'. Button names, hyperlinks, selections are normally
written in bold
9) Instruction syntax: should always be written in an active
voice: eg. 'Click Options to open the printer menu' instead of
'When the Options button is clicked on, the printer menu will open'
10) Break all modules into chapters. Frame each chapter with
a chapter slide. It's also a good idea to show the Index page
before each chapter slide with a progress indicator (I use an
animated arrow to flash next to the name of the next chapter), I
use a start button rather a 'next' button for the start of each
chapter. You should always have a module overview with the purpose
of the course and a summary slide which states what was covered and
they have complete the module.
11) Put a transparent click button somewhere on each slide.
Set the properties of the click box to take the learner back to the
start of the current chapter by pressing F2. This allows them to
jump back to the start of their chapter at any time. You can also
do a similar thing on the index pages which jumps them to another
chapter.
12) Recording video capture: best to do it at normal speed
and be concious of where your mouse is. Minimise your clicks. Most
people (until they start working with captivate) are sloppy with
their mouse and you end up with lots of unnecessarily slides that
you have to delete out. The speed will default to how you recorded
it and this will reduce the amount of time you spend on changing
timings.
13) Captions: My rule of thumb is minimum of 4 seconds - and
longer depending on the amount of words. Eg. Click 'Print Preview'
is 4 seconds, a paragraph is longer. If you creating knowledge
based modules, make the timing long (eg. 2-3 minutes) and put in a
next button so that the learner can click when they are ready.
Also, narration means the slides will normally be slightly longer.
14) Be creative: Capitvate is desk bound. There are some
learners that just don't respond no matter how interactive
Captivate can be. Incorporate non-captivate and desk free
activities. Eg. As part of our OHS module, there is an activity
where the learner has to print off the floor plan, and then wander
around the floor marking on th emap key items such as: fire exits;
first aid kit, broom and mop cupboard, stationary cupboard, etc.
Good luck!

JSF - Best Practice For Using Managed Bean

I want to discuss what is the best practice for managed bean usage, especially using session scope or request scope to build database driven pages
---- Session Bean ----
- In the book Core Java Server Faces, the author mentioned that most of the cases session bean should be used, unless the processing is passed on to other handler. Since JSF can store the state on client side, i think storing everything in session is not a big memory concern. (can some expert confirm this is true?) Session objects are easy to manage and states can be shared across the pages. It can make programming easy.
In the case of a page binded to a resultset, the bean usually helds a java.util.List object for the result, which is intialized in the constructor by query the database first. However, this approach has a problem: when user navigates to other page and comes back, the data is not refreshed. You can of course solve the problem by issuing query everytime in your getXXX method. But you need to be very careful that you don't bind this XXX property too many times. In the case of querying in getXXX, setXXX is also tricky as you don't have a member to set. You usually don't want to persist the resultset changes in the setXXX as the changes may not be final, in stead, you want to handle in the actionlistener (like a save(actionevent)).
I would glad to see your thought on this.
--- Request Bean ---
request bean is initialized everytime a reuqest is made. It sometimes drove me nuts because JSF seems not to be every consistent in updating model values. Suppose you have a page showing parent-children a list of records from database, and you also allow user to change directly on the children. if I hbind the parent to a bean called #{Parent} and you bind the children to ADF table (value="#{Parent.children}" var="rowValue". If I set Parent as a request scope, the setChildren method is never called when I submit the form. Not sure if this is just for ADF or it is JSF problem. But if you change the bean to session scope, everything works fine.
I believe JSF doesn't update the bindings for all component attributes. It only update the input component value binding. Some one please verify this is true.
In many cases, i found request bean is very hard to work with if there are lots of updates. (I have lots of trouble with update the binding value for rendered attributes).
However, request bean is working fine for read only pages and simple binded forms. It definitely frees up memory quicker than session bean.
----- any comments or opinions are welcome!!! ------

I think it should be either Option 2 or Option 3.
Option 2 would be necessary if the bean data depends on some request parameters.
(Example: Getting customer bean for a particular customer id)
Otherwise Option 3 seems the reasonable approach.
But, I am also pondering on this issue. The above are just my initial thoughts.

Best practice for upgrading task definition without deleting task instances

best practice for upgrading task definition in production system without deleting or terminating task instances
If I try and update a task definition with task instances running I get the following error:
Task definition 'My Task - Add User' may not be modified while there are active task instances
Is there a best practice to handle this. I tried to force an update through the console but that didn't work. I tried editing the task from the debug page and got the same error.

1) Rename the original task definition.
2) Upload the new task definition with the original name.
3) Later, after all the running tasks have timed out, delete the old definition.
E.g., if your task definition is "myWorkflow":
1) Rename "myWorkflow" to "myWorkflow-old-2009-07-28"
2) Upload the new task definition as "myWorkflow".
Existing tasks will stay linked to the original (renamed) workflow definition.
New tasks will use the new definition.
As the previous poster notes, depending on the changes you are making, letting the old task definitions stay active could have bad side-effects and might be better avoided.

What is best practice for conditional rendering?

i have a set of radio buttons that conditionally render another set, which in turn conditionally render a 3rd set.
i am doing this by using a valueChangeListener on an h:selectOneRadio
when i click yes on the 1st set it renders the 2nd set.
when i click yes on the 2nd set it renders the 3rd set.
when i click no on the 1st set now it correctly removes the 2nd & 3rd sets, the method also nulls the values.
when i click yes on the 1st set, it renders the 2nd set with the old values even though they were nulled. and i can see in the debugger they are still null.
so there seems to be an issue updating the model, but i dont know what that issue is. im sure it just has something to do with the way i am trying this conditional render. please see below for my first field and my valueChangeListener method.
any help with what is a best practice for this scenario would be greatly appreciated.

           * Clearing validation messages.
           * This will get around the issue with having a field
           * on the form that is both required & immediate.
          Iterator it = this.getFacesContext().getMessages();
          while (it.hasNext())
               it.next();
               it.remove();
          this.getFacesContext().renderResponse();
     }i also tried doing this another way by just using an action method attached to the a4j:support tag, but that introduced a different set of issue. so ill leave that out for now unless that is the direction someone would like to direct my issue in.
Thanks in advance

Similar issue is covered and explained here: [http://balusc.blogspot.com/2007/10/populate-child-menus.html]. Not sure if it solves your problem as you're using ajax4jsf whereas I don't, but it might give new insights. To the point you might need to bind the component(s) and use setValue(null) or setSubmittedValue(null).
