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.

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.

Best practice for updating ATWRT (Characteristic Value) in AUSP

I've notice that when we change the Characteristic Value of a Classification, that it does not update in the MM record. We have to go into MM02 for each material number that references Char Value and manually change it for row in AUSP to get updated.
Should i just create a report to Loop through and update table AUSP directly? Or is there a better way to do this via a function or BAPI etc? Wanting to know what best practice is recommended.

Hi Scott
You can use a BAPI to do that.

Best Practice for Updating Infotype HRP1001 via Class / Methods

I want to update an existing (custom) relationship between two positions.
For example I want
Position 1 S = '50007200'
Position 2 S = '50007202'
Relationship = 'AZCR'
effective today through 99991231
Is there a best practice or generally accepted way for doing this using classes/methods rather than RH_INSERT_INFTY ?
If so, please supply an example.
Thanks...

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.

Best practice for update/insert on existing/non existing rows

Hello,
In an application I want to check if a row exists and if yes I want to update the row and if not I want to insert the row.
Currently I have something like this:
begin
select *
into v_ps_abcana
from ps_abcana
where typ = p_typ
and bsw_nr = p_bsw_nr
and datum = v_akt_date
for update;
exception
when no_data_found then
v_update := false;
when others then
raise e_error_return;
end;
if v_update = false
then
/* insert new row */
else
/* update locked row */
end if;
The problem is that the FOR UPDATE lock has no effect for inserts. So if another session executes this part exactly the same time then there will be two rows inserted.
What is the best way to avoid this?

for me the 1st solution is the most efficient one.
in your 2nd solution it seems to me that you're gonna create a dummy table that will serve as a traffic cop. well that possible but not the proper and clean approach for your requirement. you're absolutely complicating your life where in fact Oracle can do it all for you.
First thing that you have to consider is your database design. This should somehow corresponds to the business rule and don't just let the program to do it on that level leaving the database vulnerable to data integrity issue such as direct data access. In your particular example, there's no way you can assure that there'll be no duplicate records in the table.
this is just an advice when designing solution: Don't use a "Mickey Mouse" approach on your design!

Best Practice for update to iPhone and iTouch

OK, when 3.0 comes down the pike, what is the best way to get 3.0 as a "clean" install? Currently 2.2.1 is on both. If I do a restore, will the system only pick up 3.0 or will it see 2.2.1 which is currently on the hard drive? With that in mind, how can I delete the 2.2.1 version of the iPhone and iTouch software? Sorry for two question in one post.
Steve H

When firmware update 2.0 was released, the entire iPhone was eraseed first including the existing firmware - just as when restoring an iPhone with iTunes, followed by 2.0 being installed, which was followed by the iPhone's backup being transferred to the iPhone.
The same may apply with firmware update 3.0 with your iPhone's backup being updated immediately before. If not, firmware version 2.2.1 will be updated with 3.0.
If 2.2.1 is updated and you want a "clean" install of 3.0, you can follow the initial upgrade by restoring your iPhone with iTunes.

Best Practice for Updating Administrative Installation Point for Reader 9.4.1 Security Update?

I deployed adobe reader 9.4 using an administrative installation point with group policy when it was released. This deployment included a transform file. It's now time to update reader with the 9.4.1 security msp.
My question is, can I simply patch the existing AIP in place with the 9.4.1 security update and redeploy it, or do I need to create a brand new AIP and GPO?
Any help in answering this would be appreciated.
Thanks in advance.

I wouldn't update your AIP in place. I end up keeping multiple AIPs on hand. Each time a security update comes out I make a copy and apply the updates to that. One reason is this: when creating the AIPs, you need to apply the MSPs in the correct order; you cannot simply apply a new MSP to the previous AIP.
Adobe's support patch order is documented here: http://kb2.adobe.com/cps/498/cpsid_49880.html.
That link covers Adode Acrobat and Reader, versions 7.x through 9.x. A quarterly update MSP can only be applied to the previous quarterly. Should Adobe Reader 9.4.2 come out tomorrow as a quarterly update, you will not be able to apply it to the 9.4.1 AIP; you must apply it to the previous quarterly AIP - 9.4.0. At a minimum I keep the previous 2 or 3 quarterly AIPs around, as well as the MSPs to update them. The only time I delete my old AIPs is when I am 1000% certain they are not longer needed.
Also, when Adobe's developers author the MSPs they don't include the correct metadata entries for in place upgrades of AIPs - any AIP based on the original 9.4.0 MSI will not in-place upgrade any installtion that is based on the 9.4.0 MSI and AIP - you must uninstall Adobe Reader, then re-install. This deficiency affects all versions of Adobe Reader 7.x through 9.x. Oddly, Adobe Acrobat AIPs will correctly in-place upgrade.
Ultimately, the in-place upgrade issue and the patch order requirements are why I say to make a copy, then update and deploy the copy.
As for creating the AIPs:
This is what my directory structure looks like for my Reader AIPs:
F:\Applications\Adobe\Reader\9.3.0
F:\Applications\Adobe\Reader\9.3.1
F:\Applications\Adobe\Reader\9.3.2
F:\Applications\Adobe\Reader\9.3.3
F:\Applications\Adobe\Reader\9.3.4
F:\Applications\Adobe\Reader\9.4.0
F:\Applications\Adobe\Reader\9.4.1
The 9.4.0 -> 9.4.1 MSP is F:\Applications\Adobe\Reader\AdbeRdrUpd941_all_incr.msp
When I created my 9.4.1 AIP, I entered these at a cmd.exe prompt - if you don't have robocopy on your machine you can get it from the Server 2003 Resouce Kit:
F:
cd \Applications\Adobe\Reader\
robocopy /s /e 9.4.0 9.4.1
cd 9.4.1
rename AdbeRdr940_en_US.msi AdbeRdr941_en_US.msi
msiexec /a AdbeRdr941_en_US.msi /update F:\Applications\Adobe\Reader\AdbeRdrUpd941_all_incr.msp /qb

Best practice for updating a list that is data bound

Hi All,
I have a List component and the data is coming in from a bindable ArrayCollection. When I make changes to the data in the bindable ArrayCollection, the change is not being reflected in the list. I notice that if I resize the browser the component redraws I suppose and then the list updates. But how can I show the update when I change the data in the bindable ArrayCollection instantly?
Thanks,
Ryan

ok thanks for that, I have it sorted out now and found out where the problem was. I got a hint from your statement: "truly [Bindable]"..
Yes, the List is using a bindable ArrayCollection but I'm also using a custom item renderer and this item renderer takes the data and sets the label fields which are not binded. I didnt know that I had to carry the "binding" all the way through. I'm overriding the "set data" function and setting the label fields similar to: myLabel.text = _data.nameHere inside that function. That's where the problem was.
It works great now that I bind the data directly to the Label fields in my custom item renderer. I'm also using functions to parse certain pieces of data too. Is this taxing on the application? I notice that the List updates everytime I scroll, and resetting / calling all the functions in my Labels in the custom itemrender (for example: myDate.text = "{parseDate(_data.date)}")
Thanks!

OIM 10g: Best practice for updating OIM user status from target recon?

We have a requirement, where we need to trigger one or more updates to the OIM user record (including status) based on values pulled in from a target resource recon from an LDAP. For example, if an LDAP attribute "disable-flag=123456" then we want to disable the OIM user. Other LDAP attributes may trigger other OIM user attribute changes.
I think I need to write a custom adapter to handle "recon insert received" and "recon update received" events from the target recon, but wanted to check with the community to see if this was the right approach. Would post-insert/post-update event handlers be a better choice?

Thanks Nishith. That's along the lines of what I was thinking. The only issue in my case is that I might need to update additional custom attributes on the OIM User in addition to enable/disable. Because of that requirement, my thought was to call the API directly from my task adapter to do the attribute updates in addition to the enable/disable. Does this seem like a sound approach?

Biztalk Best practice for update message after transformation

Hi
i have a requirement in which i have to update a message .
Message have multiple receords .
all records are created by transformation .
but i have to update i element in the record from the context .
i tried Xpath but since message have multiple receords so it didn't work .
can you suggest the best ways .
Regards,
Mohit Gupta

I assume you’re using orchestration (as you said you have tried with XPath), updating an element is part of constructing a message, so you have following options:
Message assignment, update a record using XPath.
Using external helper – pass the transformed message and context property value as two parameter to an external c# helper and update the element in the external C# helper
which would give more control.
Using context accessor functiod (codeplex one) – Use this codeplex functoid, update the relevant element in the map under transformation.
Which is best way among this, certainly using Message assignment, update the record using XPath. If you have any issues I would try to solve it. I can’t comment on your
issue in using XPath as I don’t know the complexity of the XML record structure. But better options in this.
Using external helper, give more control where you have complete flexibility of using C#, so you can easily debug, complete control over the XML message (which also there
in Orch, but in C# it much easier). But problem with this approach is, you will have additional assembly to manage.
Least favoured among the options is context accessor functoid, still does the job, but overhead of managing a custom functiod to do this work.
You can choose the one which suits your need best.

Best Practices for FSCM Multiple systems scenario

Hi guys,
We have a scenario to implement FSCM credit, collections and dispute management solution for our landscape comprising the following:
a 4.6c system
a 4.7 system
an ECC 5 system
2 ECC6 systems
I have documented my design, but would like to double check and rob minds with colleagues regarding the following areas/questions.
Business partner replication and synchronization: what is the best practice for the initial replication of customers in each of the different systems to business partners in the FSCM system? (a) for the initial creation, and (b) for on-going synchronization of new customers and changes to existing customers?
Credit Management: what is the best practice for update of exposures from SD and FI-AR from each of the different systems? Should this be real-time for each transaction from SD and AR (synchronous) or periodic, say once a day? (assuming we can control this in the BADI)
Is there any particular point to note in dispute management?
Any other general note regarding this scenario?
Thanks in advance. Comments appreciated.

Hi,
I guess when you've the informations that the SAP can read and take some action, has to be asynchronous (from non-SAP to FSCM);
But when the credit analysis is done by non-SAP and like an 'Experian', SAP send the informations with invoices paid and not paid and this non-SAP group give a rate for this customer. All banks and big companies in the world does the same. And for this, you've the synchronous interface. This interface will updated the FSCM-CR (Credit), blocking or not the vendor, decreasing or increasing them limit amount to buy.
So, for these 1.000 sales orders, you'll have to think with PI in how to create an interface for this volume? What parameters SAP does has to check? There's an time interval to receive and send back? Will be a synchronous or asynchronous?
Contact your PI to help think in this information exchange.
Am I clear in your question?

Best practice for Spark repeating background image in a SkinnableContainer?

In my old Flex 3.5 code I would accomplish this by dropping an Image into a Canvas and hitting the Canvas with some css style stuff to get the repeat. The Image tag had a source property that would take a web address so I could dynamically grab different images from the web based on some conditions. Little bit more trouble with Flex 4.5 and Spark but I'm trying to get there.
Here Adobe docs explain how to *embed* a background image:
http://help.adobe.com/en_US/flex/using/WS422719A4-7849-4921-AF39-57FF567B483B.html#WS063B0 491-B7AB-4b00-A39F-E44310BCB0E0
They use a BitmapFill object in the skin.

    <s:Rect id="background" left="3" top="3" right="3" bottom="3" alpha=".25">
        <s:fill>
            <s:BitmapFill source="@Embed(source='../../assets/myImage.jpg')"/>
        </s:fill>
    </s:Rect>
Problem is I need to do this without embedding the image. In my old code I grabbed the image from web (set source property on Image tag to web address). What's the best practice for achieving this with a skinnable container? The BitmapFill object used above won't take a web address for a source.
Thanks in advance.

Use BitmapImage with a fillMode of repeat:
<s:BitmapImage source="http://www.google.com/intl/en_com/images/srpr/logo2w.png" width="100%" height="100%" scaleMode="stretch" fillMode="repeat" />

Best Practice for Handling Timeout

Hi all,
What is the best practice for handling timeout in a web container?
By the way, we have been using weblogic 10.3
thanks

Are you asking about this specific to web services, or just the JEE container in general for a web application?
If a web application, Frank Nimphius recently blogged a JEE filter example that you could use too:
