Best practice for IE cache

Hi, all.
Over the weekend, we applied the SPS17 to the ECC6.0 server running on dual stack. We also updated the HCM EHP3 to stack 6.
We have a lot of WD for ABAP and WD for JAVA applications running on the ECC dual stack server. The contents are federated to the consumer portal running on EP7.0 SPS21. Note the consumer was NOT patched during the weekend.
On Monday morning, we get many calls from users that their HCM apps are not working on the consumer portal. The error can come in many different ways. The fix so far is to clear their IE cache and everything works again. Note that the problem doesn't happen to everybody, less than 10% of the user population. But the 10% is enough to flood our helpdesk with calls.
I am not sure if any of you has run into this problem before. Is that a best practice to delete the IE cache from all the users after an SP upgrade? Any idea to see what caused the error?
Thanks,
Jonathan.

Hi Jonathan,
I have encountered a similar situation before but have unfortunately never got to the root cause of it. One thing I did notice was that browser versions tended to affect how the cache was handled for local users. We noticed that IE7 handled changes in the WDA apps much better than certain versions of IE6. Not sure if this is relevant in your scenario.
I assume also that you are not using ACCAD or other WAN acceleration devices (as these have their own cache that can break on upgrades) and that you've cleared out your portal caches for good measure. As far as I know in ITS, if you've stopped and started the WDA services during the upgrade then the caching shouldn't be a problem.
Cheers,
E

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...

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!!

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

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

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

What are best practice for packaging and deploying j2EE apps to iAS?

We've been running a set of J2EE applications on a pair of iAS SP1b for about a year and it has been quite stable.
Recently however we have had a number of LDAP issues, particularly when registering and unregistering applications (registering ear files sometimes fails 1st time but may work 2nd time). Also We've noticed very occasionally that old versions of classes sometimes find their way onto our machines.
What is considered to be best practice in terms of packaging and deployment, specifically:
1) Packaging - using the deployTool that comes with iAS6 SP1b to package is a big manual task, especially when you have 200+ jsp files. Are people out there using this or are they scripting it with a build tool such as Ant?
2) Deploying an existing application to multiple iAS's. Are you guys unregistering old application then reregistering new application? Are you shutting down iAS whilst doing the deployment?
3) Deploying ear files can take 5 to 10 mins, is this normal?
4) In a clustered scenario where HTTPSession is shared what are the consequences of doing deployments to data stored in session?
thanks in asvance for your replies
Owen

You may want to consider upgrading your application server environment to a newer service pack. There are numerous enhancements involving the deployment tool and run time layout of your application that make clear where you're application is loading its files from.
If you've at a long running application server environment, with lots of deployments under your belt, you might start to notice slow downs in deployment and kjs start time. Generally this is due to garbage collecting in your iAS registry.
You can do several things to resolve this. The most complete solution is to reinstall the application server. This will guarantee a clean ldap registry. Of course you've got to restablish your configurations and redeploy your applications. When done, backup your application server install space with the application server and directory server off. You can use this backup to return to a known configuation at some future time.
For the second method: <B>BE CAREFUL - BACKUP FIRST</B>
There is a more exhaustive solution that involves examining your deployed components to determine the active GUIDS. You then search the NameTrans section of the registry searching for Applogic Servlet *, and Bean * entries that represent your previously deployed components but are represented in the set of deployed GUIDs. Record these older GUIDs, remove them from ClassImp and ClassDef. Finally remove the older entries from NameTrans.
Best practices for deployment depend on your particular environmental needs. Many people utilize ANT as a build tool. In later versions of the application server, complete ANT scripts are included that address compiling, assembly and deployment. Ant 1.4 includes iAS specific targets and general J2EE targets. There are iAS specific targets that can be utilized with the 1.3 version. Specialized build targets are not required however to deploy to iAS.
Newer versions of the deployment tool allow you to specify that JSPs are not to be registered automatically. This can be significant if deployment times lag. Registered JSP's however benefit more fully from the services that iAS offers.
2) In general it is better to undeploy then redeploy. However, if you know that you're not changing GUIDs, recreating an existing application with new GUIDs, or removing registered components, you may avoid the undeploy phase.
If you shut down the KJS processes during deployment you can eliminate some addition workload on the LDAP server which really gets pounded during deployment. This is because the KJS processes detect changes and do registry loads to repopulate their caches. This can happen many times during a deployment and does not provide any benefit.
3) Deploying can be a lengthy process. There have been improvements in that performance from service pack to service pack but unfortunately you wont see dramatic drops in deployment times.
One thing you can do to reduce deployment times is to understand the type of deployment. If you have not manipulated your deployment descriptors in any way, then there is no need to deploy. Simply drop your newer bits in to the run time space of the application server. In later service packs this means exploding the package (ear,war, or jar) in to the appropriate subdirectory of the APPS directory.
4) If you've changed the classes of objects that have been placed in HTTPSession, you may find that you can no longer utilize those objects. For that reason, it is suggested that objects placed in session be kept as simple as possible in order to minimize this effect. In general however, is not a good idea to change a web application during the life span of a session.

Best Practice for disparately sized data

2 questions in about 20 minutes!
We have a cache, which holds approx 80K objects, which expired after 24 hours. It's a rolling population, so the number of objects is fairly static. We're over a 64 node cluster, high units set, giving ample space. But.....the data has a wide size range, from a few bytes, to 30Mb, and everywhere in between. This causes some very hot nodes.
Is there a best practice for handling a wide range of object size in a single cache, or can we do anything on input to spread the load more evenly?
Or does none of this make any sense at all?
Cheers
A

AHi A,
It depends... if there is a relationship between keys and sizes, e.g. if this or that part of the key means that the size of the value will be big, then you can implement a key partitioning strategy possibly together with keyassociation on the key in a way that it will evenly spread the large entries across the partitions (and have enough partitions).
Unfortunately you would likely not get a totally even distribution across nodes because of having fairly small amount of entries compared to the square of the number of nodes (btw, which version of Coherence are you using?)...
Best regards,
Robert

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

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.

Where to find best practices for tuning data warehouse ETL queries?

Hi Everybody,
Where can I find some good educational material on tuning ETL procedures for a data warehouse environment? Everything I've found on the web regarding query tuning seems to be geared only toward OLTP systems. (For example, most of our ETL
queries don't use a WHERE statement, so the vast majority of searches are table scans and index scans, whereas most index tuning sites are striving for index seeks.)
I have read Microsoft's "Best Practices for Data Warehousing with SQL Server 2008R2," but I was only able to glean a few helpful hints that don't also apply to OLTP systems:
often better to recompile stored procedure query plans in order to eliminate variances introduced by parameter sniffing (i.e., better to use the right plan than to save a few seconds and use a cached plan SOMETIMES);
partition tables that are larger than 50 GB;
use minimal logging to load data precisely where you want it as fast as possible;
often better to disable non-clustered indexes before inserting a large number of rows and then rebuild them immdiately afterward (sometimes even for clustered indexes, but test first);
rebuild statistics after every load of a table.
But I still feel like I'm missing some very crucial concepts for performant ETL development.
BTW, our office uses SSIS, but only as a glorified stored procedure execution manager, so I'm not looking for SSIS ETL best practices. Except for a few packages that pull from source systems, the majority of our SSIS packages consist of numerous "Execute
SQL" tasks.
Thanks, and any best practices you could include here would be greatly appreciated.

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.

Best practices for setting up users on a small office network?

Hello,
I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
Thank you,

Hi,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

Best-practice for Catalog Views ? :|

Hello community,
A best practice question:
The situtation: I have several product categories (110), several items in those categories (4000) and 300 end-users. I would like to know which is the best practice for segment the catalog. I mean, some users should only see categories 10,20 & 30. Other users only category 80, etc. The problem is how can I implement this ?
My first idea is:
1. Create 110 Procurement Catalogs (1 for every prod.category). Each catalog should contain only its product category.
2. Assign in my Org Model, in a user-level all the "catalogs" that the user should access.
Do you have any idea in order to improve this ?
Saludos desde Mexico,
Diego

Hi,
Your way of doing will work, but you'll get maintenance issues (to many catalogs, and catalog link to maintain for each user).
The other way is to built your views in CCM, and assign these views to the users, either on the roles (PFCG) or on the user (SU01). The problem is that with CCM 1.0 this is limitated, cause you'll have to assign one by one the items to each view (no dynamic or mass processes), it has been enhanced in CCM 2.0.
My advice:
-Challenge your customer about views, and try to limit the number of views, with for example strategic and non strategic
-With CCM 1.0 stick to the procurement catalogs, or implement BADIs to assign items to the views (I experienced it, it works, but is quite difficult), but with a limitated number of views
Good luck.

Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.
Thanks

Best practice for multi-language content in common areas

I've got a site with some text in header/footer/nav that needs to be translated between an English and Spanish site, which use the same design. My intention was to set up all the text as content to facilitate. However, if I use a standard dialog with the component's path set to a child of the current page node, I would need to re-enter the text on every page. If I use a design dialog, or a standard dialog with the component's path set absolutely, the Engilsh and Spanish sites will share the same text. If I use a standard dialog with the component's path set relatively (eg path="../../jcr:content/myPath"), the pages using the component would all need to be at the same level of the hierarchy.
It appears that the Geometrixx demo doesn't address this situation, and leaves copy in English. Is there a best practice for this scenario?

I'm finding that something to the effect of <cq:include path="<%= strCommonContentPath + "codeEntry" %>" resourceType ...
works fine for most components, but not for parsys, or a component containing a parsys. When I attempt that, I get a JS error that says "design.path is null or not an object". Is there a way around this?
