1130 Radio Mounting Best practice

Hi Everyone.
In discussions with cisco and other users, we are confused on mounting and radio coverage practices.
should we be mounting the radio vertically with the ethernet to the side or Horizontal to the floor (drop ceiling).
According to others, if the AP is mounted vertically (wall mount) and the ethernet entering from the bottom, the radio plane is north and south (coverage would be up and down).
Anyone have more clear info on this?
Does anyone have

Hi Brad,
Thanks for your reply. I do agree with you.
I have a Cisco certified company who designs and installs wireless who are telling some of our Customers otherwise. They are stating the AP's should be hung vertically (wall mount) with the ethernet entering to the left side due to the internal OmniDirectional Radio.
I have read nothing in Cisco Doc's to make this statement true.
I have been told by Cisco that due to Location tracking algorithms on LWAPP configured 1130's that the Horizontal mount is official. Notice the "LWAPP" !!!! and does this still hold true for Autonomous 1130AP's?

Physical mounting; best practice ?

Is there a whitepaper as to the best practice for orientation, location and height of the Time Capsule?
Maybe what I am after is a 3D transmission envelope diagram to determine the perfect mounting orientation and location in our unique situation.

http://h-sq.com/products/airmount/index.html
This is a way to mount the Time Capsule. As for a radio map, I have not seen one. But it would help to raise it up so that there might be less line of sight blocks.

Best Practice for validating radio buttons

Hi,
I'm building a form which has quite a lot of questions that a
user answers my selecting a radio button. All the questions are
required. Could someone please advise me what the best practice is
for validating a radio button in a radio button group is checked?
There doesn't seem to be much information out there on this
one???
Thanks...

Have you found a solution? If yes can you please give me a

Best practiceS for setting up Macs on Network

Greetings.
We have six Macs on our Windows Server network; three iMacs and three laptops. We have set up all the machines and they are joined to the Active Directory. In the past, we have always created local users on the machines and then "browsed" to the server shares and mounted the them. We've learned things have improved/changed over the years and we're just now realizing we can probably have the machines set up to work better. So, I have a couple of questions for "best practices" when setting up each of the machines.
1. Since we’re in a network environment, should we not set up “local logins/users” and instead have users login using their AD login? It seems having a local account creates some conflicts with the server since upgrading to lion.
2. Should we set the computer to not ask for a “list of users” and instead ask for a username and password for logins?
3. For the user that uses the machine most often, they can still customize their desktop when they use an AD login, correct?
4. Should we set up Mobile User Accounts? What exactly does this do?
Any other advice on how we should best be setting up the clients for our environment to make sure we are following best practices would be great!
Thanks for any help!

Best practice architecture Wireless security

What is the best practice architecture for wireless to the wire network?
Use AP to Firewall and it to a router using RADIUS?
It apply to Control is a safety?
What models Cisco recomend (Hard and Soft?)
Is any place in Cisco that I can use to see Architecture recomendations that integrete Wireless, Radio (Microwave) and Voice over IP com-plete system?

using one of the 802.1x types (i.e. LEAP, EAP-FAST, PEAP) with WPAv2 (AES encryption). Too bad that there are not many wireless adapters support AES.
All Cisco wireless product support AES in 12.3(2)JA recently.
Also, you may want to configure WDS for radio management.

Best Practice for Distributed TREX NFS vs cluster file systems

Hi,
We are planning to implement a distributed TREX, using RedHat on X64, but we are wondering which could be the best practice or approach to configure the "file server" used on the TREX distributed environment. The guides mention file server, that seems to be another server connected to a SAN exporting or sharing the file systems required to be mounted in all the TREX systems (Master, Backup and Slaves), but we know that the BI accelerator uses OCFS2 (cluster file systems) to access the storage, in the case of RedHat we have GFS or even OCFS.
Basically we would like to know which is the best practice and how other companies are doing it, for a TREX distributed environment using either network file systems or cluster file systems.
Thanks in advance,
Zareh

I would like to add one more thing, in my previous comment I assumed that it is possible to use cluster file system on TREX because BI accelerator, but maybe that is not supported, it does not seem to be clear on the TREX guides.
That should be the initial question:
Aare cluster file system solutions supported on plain TREX implementation?
Thanks again,
Zareh

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.

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).

Best Practice: Deploying Group Policy to Users on different OUs

Greetings, everyone! I am needing some advice on how to deploy some group policy objects to specific users stored on different OUs.
Let me set the stage: I work for a large school district, and have recently taken over the district's career center. The idea behind the career center is that students from different high schools around the city come in to take classes based on their choice
of career, such as radio broadcasting or auto mechanic and such. The AD structure is set up so that each school has their own OU. When a user (staff, student, etc.) is assigned to a school OU, they automatically are added to
their school's security group (i.e. EASTHIGH-STUDENT), and that when any user moves from one school to another, we have to move their AD account to that school's OU, which will remove the security group from the old school and apply the new school
security group.
For the career center, since we have students coming from different buildings every day, rather than trying to find a way to move their AD account from their high school OU to the career center OU, the previous techs created generic accounts (such as tv001,
tv002, etc.) in AD and stored them in the career center OU. This way, teachers can assign students that particular generic account so that they can access the drives and printers from the career center, as well as access the career center network
drives while they are at their home high school.
Since I have moved to the career center, and apparently I have more knowledge about group policy than most of the techs in the district, the district system engineers want me to remove all of the generic accounts from the career center OU, and have students
use their own AD accounts. Obviously I also want to do this since the generic accounts are very confusing to me, but I'm trying to figure out the best way to do this.
For simplicity sake, I'm just going to start off by figuring out how to set up a group policy for mapping the career center drives. Now, I obviously know that the best way would be to create security groups for each career area, and that we would need
to add students to those groups so that only those particular students would get the GPO for the career center, but my question is where would I like the group policies to? Do I need to link it at the root of the domain so that every OU is hit?
Just curious about this.
Thanks!

Don't link it to the root.... apply the drive mapping as a policy at the OU or you could apply the drive mapping using Group Policy Preferences using security group targeting... .I would also strongly recommend you check out my articles

– Part 1

Hope it helps...

OVM Repository and VM Guest Backups - Best Practice?

Hey all,
Does anybody out there have any tips/best practices on backing up the OVM Repository as well ( of course ) the VM's? We are using NFS exclusively and have the ability to take snapshots at the storage level.
Some of the main points we'd like to do ( without using a backup agent within each VM ):
backup/recovery of the entire VM Guest
single file restore of a file within a VM Guest
backup/recovery of the entire repository.
The single file restore is probably the most difficult/manual. The rest can be done manually from the .snapshot directories, but when we're talking about having hundreds and hundreds of guests within OVM...this isn't overly appealing to me.
OVM has this lovely manner of naming it's underlying VM directories off of some abiguous number which has nothing to do with the name of the VM ( I've been told this is changing in an upcoming release ).
Brent

Please find below the response from the Oracle support on that.
In short :
- First, "manual" copies of files into the repository is not recommend nor supported.
- Second we have to go back and forth through templates and http (or ftp) server.
Note that when creating a template or creating a new VM from a template, we're tlaking about full copies. No "fast-clone" (snapshots) are involved.
This is ridiculous.
How to Back up a VM:1) Create a template from the OVM Manager console
Note: Creating a template requires the VM to be stopped (this is required because the if the copy of the virtual disk is done with the running will corrupt data) and the process to create the template make changes to the vm.cfg
2) Enable Storage Repository Back Ups using the step above:
http://docs.oracle.com/cd/E27300_01/E27309/html/vmusg-storage-repo-config.html#vmusg-repo-backup
2) Mount the NFS export created above on another server
3) Them create a compress file (tgz) using the the relevant files (cfg + img) from the Repository NFS mount:
Here is an example of the template:
$ tar tf OVM_EL5U2_X86_64_PVHVM_4GB.tgz
OVM_EL5U2_X86_64_PVHVM_4GB/
OVM_EL5U2_X86_64_PVHVM_4GB/vm.cfg
OVM_EL5U2_X86_64_PVHVM_4GB/System.img
OVM_EL5U2_X86_64_PVHVM_4GB/README
How to restore up a VM:1) Then upload the compress file (tgz) to an HTTP, HTTPS or FTP. server
2) Import to the OVM manager using the following instructions:
http://docs.oracle.com/cd/E27300_01/E27309/html/vmusg-repo.html#vmusg-repo-template-import
3) Clone the Virtual machine from the template imported above using the following instructions:
http://docs.oracle.com/cd/E27300_01/E27309/html/vmusg-vm-clone.html#vmusg-vm-clone-image

Best practice for CM log and Out

Hi,
I've following architecture:
DB SERVER = DBSERVER1
APPS SERVER =APP1 AND APP2
LB= Netscaler
PCP configured.
What is the best practice to have CM log and out? Do I need to keep these files on DB server and mount to APP1 and APP2?
Please advice.
Thanks

Hi,
see if you want to save the logfiles of other cm node when crash happens then why u want to share APPLCSF?if the node which is hosting shared APPLCSF gets crashed then ALL the logfiles(of both nodes) are gone, keep same directories and path of APPLCSF on both the nodes,so the CMNODE(A) have logfiles local in its directories and CMNODE(B) have logfile local in its directories....
In the last what ever i said above was my thinking so follow it or not its u r wish,But always follow what oracle says...the poster should also check with oracle.

Best practice for partitioning 300 GB disk

Hi,
I would like to seek for advise on how I should partition a 300 GB disk on Solaris 8.x, what would be the optimal size for each of the partition.
The system will be used internally for running web/application servers and database servers.
Thanks in advance for your help.

There is no "best practice" regardles of what others might say. I depends entirely on how you plan on using and maintaining the system. I have run into too many situations where fine-grained file system sizing bit the admins in the backside. For example, I've run into some that assumed that /var is only going to be for logging and printing, so they made it nice and small. What they didn't realize is that patch and package information is also stored in /var. So, when they attempted to install the R&S cluster, they couldn't because they couldn't put the patch info into /var.
I've also run into other problems where a temp/export system that was mounted on a root-level directory. They made the assumption that "Oh, well, it's root. It can be tiny since /usr and /opt have their own partitions." The file system didn't mount properly, so any scratch files in that directory that were created went to the root file system and filled it up.
You can never have a file system that's too big, but you can always have a file system that's too small.
I will recommend the following, however:
* /var is the most volatile directory and should be on its own several GB partition to account for patches, packages, and logs.
* You should have another partition as big as your system RAM and assign that parition as a system/core dump for system crashes.
* /usr or whatever file system it's on must be big enough to assume that it will be loaded with FOSS/Sunfreeware tools, even if at this point you have no plans on installing them. I try to make mine 5-6 GB or more.
* If this is a single-disk system, do not use any kind of parallel access structure, like what Oracle prefers, as it will most likely degrade system performance. Single disks can only make single I/O calls, obviously.
Again, there is no "best practice" for this. It's all based on what you plan on doing with it, what applications you plan on using, and how you plan on using it. There is nothing that anyone here can tell you that will be 100% applicable to your situation.

Best practice DISK Layout for E-business suite 11i or R12 in SAN enviornmen

Hi,
Does any one have any document on best practices on DISK Layout for E-business suite 11i or R12 in SAN enviornment?
My thoughts are :
Mount point 1 =Oracle Binary
Mount point 2 =Data files
Mount point 2 =Index files
Mount point 2 =Archived logs
Please suggest

On our HPUX node, we have each environment (PROD, TEST, DEV) on it's own separate mountpoint. Each mountpoint is a separate LUN (Vdisk) on our SAN (an HP EVA4400). No performance issues at all. Our Windows nodes runs Apache and forms, and that is on the internal disks on the windows machine itself. Hope this helps.

WLC 5508 - config best practices - large deposit

Hello everyone, I recently added a Cisco 5508 to control many LAPs on a very large deposit.
We have indoor and outdoor LAPs on the environment. Many Hand Helds using 802.11b.
I was wondering if anyone can tell me if there is a best practice for environments with:
- 802.11b client devices.
- 802.11g client devices.
- indoor/outdoor LAP.
- high-density mineral water/soda on the deposit.
- LAPs are 1240 (indoor) and 1310 (outdoor).
- Antennas are 1728 and 2506 respectively.
Among that, on the log I see continous entries of reassociate and reauthentication for the same devices, but not equal logs of deauthentication.
Thanks in advance.
Regards

for instance, I have this recent log:

Could be this because of excessive roaming?. If yes, how can I prevent it?.
Two of the 3 LAPs reported are very close one of each other, but the 3° LAP is over 60 meters or more from the other two.
The 3 LAPs are using 5,2 dBi antennas.

What is the best practice to roll out ApEx to production?

Hi,
My first ApEx application :) What is the best practice to deploy an ApEx application to production?
Also, I created end users account and use the end user's accountsto log in to ApEx via URL (http://xxx.xxx.xxx:8080/apex/f?p=111:1). However, how come sometimes it's still in development mode (ie: with the Home|Application#|Edit Page#|Create|Session|... ) tool bar showing up at the bottom, but sometimes not?
Thanks much :)
Helen

When you setup your users, make sure the radio button for both workspace admin and developer are set to No. This should make them an "end user" and they should not see the links. Only developers and workspace admins can see it.

Use Best Practice to Import Master Data

Hi,
I am SAP beginner, i glad someone can guide me on my issue. How can I using best practice to import 1000++ material master data into SAP system ??? I already prepared the data in Excel spreadsheet. Can any one guide me on step?
Thanks.

Hi,
LSMW is a very good tool for master data upload. The tool is very rich in features is also complex. Being a beginner you should check with a consultant to know how you can use LSMW to upload your 1000 + records. The tool too is quite intuitive. After entering the LSMW transaction you create the project, subproject and the object you are going to work on uploading. When u enter the next screen you see several radio buttons. Typically every upload required all the features behind those radio buttons and in the same sequence. It is not possible to give the details to be performed in each of these radio buttons in this forum. Please take a consultant's help in your vicinity.
thanx
