What are best practices for rolling out cluster upgrade?

Hello,
I am looking for your input on the approaches to implement Production RAC upgrade without having a spare instance of RAC servers. We have a 2-node database RAC 11.1 on Production. We are planning to upgrade to 11.2 but only have a single database that the pre-Production integration can be verified on. Our concern is that the integration may behave differently on RAC vs. the signle database instance. How everybody else approaches this problem?

you want to test RAC upgrade on NON RAC database. If you ask me that is a risk but it depends on may things
Application configuration - If your application is configured for RAC, FAN etc. you cannot test it on non RAC systems
Cluster upgrade - If your standalone database is RAC one node you can probably test your cluster upgrade there. If you have non RAC database then you will not be able to test cluster upgrade or CRS
Database upgrade - There are differences when you upgrade RAC vs non RAC database which you will not be able to test
I think the best way for you is to convert your standalone database to RAC one node database and test it. that will take you close to multi node RAC

What are best practices for managing my iphone from both work and home computers?

What are best practices for managing my iphone from both work and home computers?

Sync iPod/iPad/iPhone with two computers
Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans withiTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entires and import the local content you have on that box.

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

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.

What are best practices for connecting asa to nexus 5000

just trying to get a feel for the best way to connect redundant asa to redundant nexus 5000
using a vpc vlan is fine, but then running a routing protocol isn't supported, so putting static routes on 5000 works, but it doesn't support ip sla yet so you cant really stop distributing the default if your internet goes down. just looking for what was recommended.

What are best practices for back up drives when they become full?

I've got an external hard drive that is now full. What do I do? Delete the oldest files on it, right? If so, do I delete the full backup and ALL the incremental backups since then? Do I have to do this manually now; isn't there a way to automate this?

The "usual" procedure is to move the oldest incremental backups from the hard drive to permanent storage media such as DVD.
However, if your backup drive is the same size as your main drive, then you could do incremental backups that delete files on the backup druve that have been deleted from the source drive. This prevents the drive from filling up with old and out of date files. However, if you need to maintain archives of even the incremental backups, then move the oldest to permanent storage media and delete them from the backup drive to free space.
Visit The XLab FAQs and read the FAQ on backup and restore for more information.

Microsoft best practices for patching a Cluster server

Good morning! I was wondering if you had any web resources (Webcasts) or whitepapers on Microsoft best practices for patching a Cluster server? I will list what I seen online; the third one was very good:
Failover Cluster Step-by-Step Guide: Configuring a Two-Node File Server Failover Cluster

Patching Windows Server Failover Clusters
http://support.microsoft.com/kb/174799/i

Hi Vincent!
I assume this step-by-step guide can also be used if you have more then 2 nodes, as long as you make sure majority of nodes are up (and quorum disk is available).
I just had a strange experience during maintenance of 2 nodes (node nr 7 and nr 8) in a 8 node hyper-v cluster R2 SP1 with CSV. I used SCVMM2012 to put the nodes in maintenance mode. (live migrating all resources to other nodes.) I then look in "Failover cluster
manager" to check that the nodes had been "Paused". And yes everything was just fine. I then did windows update and restartet, no problem. But after restart I wanted to run PSP (HP's update utility) to update some more drivers,software etc. During this PSP
update, node nr 02 suddenly failed. This node is not even a HP Blade, so I'm not sure how, but I know network NIC drivers and software where updated from PSP. So my question is:
Does changes in "Network Connections" on nodes in "Pause" mode affect other nodes in the cluster?
The network are listed as "Up" during Pause mode, so the only thing I could think of is that during PSPs driver/software update, NICs on node 07 and 08 were going down and up differently somehow making Node 02 fail.
So now during maintenance (Vendor driver/software/firmware updates, not MS Patches) I first put the node in "Pause" mode then I stop cluster service, (and change it to disabled) making sure nothing can affect the cluster.

What is best practice for installing Yosemite

I am currently on OS X Mavericks version 10.9.5 Macbook pro 13. 2.6 ghz intel for i5, 8gb 1600 mhz ddr3.
I am now downloading yosemite 10.10.1 but since i've been reading all these negative feedback so far, i am having second thoughts if i should continue to install the upgrade or not.
Any suggestion What is best practice for installing Yosemite? Or is it not yet time to upgrade since the platform is premature yet?
Thanks in advance.

Check your apps are compatible with 10.10 - roaringapps.com
http://www.etresoft.com/etrecheck can show what is running & installed - look for updates on the developer own sites.
If you have many kernel extensions or startup items look for updates to them too
Take a full bootable backup to another disk via Carbon Copy Cloner, Super Duper! or Disk Utility
Disconnect the backup before you begin any install (ideally set it aside & leave it untouched incase you need to go back to 10.9)
Personally I prefer a clean install when there are signs of multiple migrations (if you have upgraded several OS for a period of years). Setup Assistant/ Migration Assistant can import user data from a backup, but consider that Apps & 'other data' should be manually reinstalled from the latest versions.
If you clean install (erase the HD before installation) then make sure you deauthorise iTunes & any other apps that are associated online (like find my Mac).

What's best practice for logging messages in pageflow?

What's best practice for logging messages in pageflow?
Workshop complains when I try to use a Log4J logger by saying it's not serializable. Is there a context similar to JWSContext that you can get a logger from?
There seems to be a big hole in the documentation on debug logging in workflows and JSP pages.
thanks,
Rodger...

Make the configuration change in setDomainEnv.cmd. Find where the following variable is set:
LOG4J_CONFIG_FILE
and change it to your desired path.
In your Global.app class, instantiate a static Logger like this:
transient static Logger logger = Logger.getLogger(Global.class);
You should be logging now as long as you have the categories and appenders configured properly in your log4j.xml file.

Best practices for an oracle application upgrade

Hello,
We have an enterprise application deployed on Oracle Weblogic and connecting to an Oracle database (11g).
The archive is versioned and we are using Weblogic's feature to upgrade to new versions and retire old versions.
In a case of emergency when we need to rollback an upgrade, the job is really easy on Weblogic but not the same on Oracle DB.
For most of our releases, the release package is an ear plus some database scripts.
Releases are deployed with minimum downtime, so while we are releasing our clients are still writing to the DB.
In case of a rollback is needed, we need to make sure the changes we made to the DB structure (Views, SP, Tables...) are reverted but data inserted by clients stayed intact.
Correct me if I am wrong, but Flashback and RMAN TSPITR are not the good options here.
What other people usually do in similar cases? What are best practices and deployment plans for our case?
Guides and direction are welcomed.
Thanks!

Hi Magnus
I guess you have to install again to ensure no problems. BP installation also involves ensuring correct SP levels (cannot be higher) for all software components.

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.

               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).

What is best practice for dealing with Engineering Spare Parts?

Hello All,
I am after some advice regarding the process for handling engineering spare parts in PM. (We run ECC 5)
Our current process is as follows:
All materials are set up as HIBE's
Each material is batch managed
The Batch field is used for the Bin location
We are now looking to role out PM to a site that has in excess of 50,000 spare parts and want to make sure we use best practice for handling the spare parts. We are now considering using a basic WM setup to handle the movement of parts.
Please can you provide me with some feedback on what you feel the best practice is for dealing with these parts?
We are looking to set up a solution that will us to generate pick lists etc and implment a scanning solution to move parts in and out of stores.
Regards
Chris

Hi,
I hope all the 50000 spare parts are maintained as stock items.
1. Based on the usage of those spare parts, try to define safety stock & define MRP as "Reorder Point Planning". By this, you can avoid petty cash purchase.
2. By keeping the spare parts (atleast critical components) in stock, Planned Maintenance as well as unplanned maintenance will not get delayed.
3. By doing GI based on reservation, qty can be tracked against the order & equipment.
As this question is MM & WM related, they can give better clarity on this.
Regards,
Maheswaran.

Best practice for checking out a file

Hello,
What is the SAP best practice to check out a file? (DTR -> EDit or DTR -> Edit Exclusive?)
What are pros and cons of checking out a file exclusively?
Thanks

Thanks Pascal.
Also, I think if a developer checks out exclusively, makes changes and leaves the company without checking in, the only way is to revert those files in which case all his changes will be gone.

New mac - what is best practice for accounts?

I am about to get a new mac (imac g5), and would like it to work well (ie file transfer and backup to from) my existing powerbook.
Is there a best practice for account set up? should I use the same accounts between the two or can I set up a new account on the new mac?
Related to this: what will key change sync give me? does that only work with the same accounts on two macs?
thanks
John

With Tiger there is a migration assistant that will move everything over from your Powerbook to your new iMac G5. All you need is a firewire cable and when prompted in your first start-up select migration assistant and connect the two computers. You will need to boot up your Powerbook holding down the 't' key before you connect the two together. Good luck, Jack.
