Lync network RTT requirements?

We currently have Lync Enterprise set up in one data center that does not have direct Internet connectivity. We are planning on setting up an Edge and Director server, where the Edge server is in our DMZ in another data center. The RTT between
these two networks is about 80ms. Is there any documentation regarding RTT requirements (e.g. for SharePoint, RTT must be <1ms between each server in the farm)? Is there any documentation about the placement of the Director?
http://sharepoint.nauplius.net

The Lync server planning guide gives the following advice "Provision your network to ensure a maximum end-to-end delay (latency) of 150 milliseconds (ms) under peak load. Latency
is the one network impairment that Lync Server media components cannot reduce, and it is important to find and eliminate the weak points." The guide is available for download
here and the quote comes from Chapter 2, which deals with infrastructure requirements.
You should allow for the latency introduced by the firewall.
The Director should be on the internal network. Since the Director is used to authenticate user, it would be best to locate it wherever most of the users are located. The Director
drops out of the path once it forwards internal users to their home pool. For external users, the Director stays in the communications path, so keep this in mind when deciding on location.
Finally, you might not be aware that the Director is an optional role.
Hope that helps.

Network Security Requirement : Confidential - Not Enforced

I am having a perplexing problem with the network security requirement feature in SJSAS 8 Update 1.
In deploytool, under my WAR, in the security tab, for my only SecurityConstraint, I set the Network Security Requirement to CONFIDENTIAL. This should cause any access to thse objects over port 80 to be redirected to https via for 443.
The failure is that it does not redirect clients accessing over port 80 to a secure connection. The tricky part is that it fails in a completely random way. Sometimes for some WARs it will work as expected, then after X number of server restarts / redeployments, some of the same WARs will not do the redirect as expected. Through continuous redeploys and restarts during development, all WARs will or will not do the redirect in any given situation.
Has anyone else experienced this problem and worked around it? Any help is greatly appreciated! Thanks in advance!

The following is the deployment descriptor for one of the WARs (this problem affects them all, on multiple different machines with different setups).
The following is from the Security Contraint:

Problems joining Wi-Fi networks that require viewing a redirect page in iOS 8.1.1? Check your "Auto-Login" setting.

Are you having problems joining previously used Wi-Fi networks that require you to view a login or redirect page (say to accept Terms of Use) first? The problem could be your Auto-Login Wi-Fi network setting.
I found numerous cases where I could not access in-store Wi-Fi networks (Nordstrom was one), hotel networks or in fact networks where you had to first view a Terms and Conditions page or where you had to login via a web form.
These were all networks I had used before.
This appears to be due to the "Auto-Login" setting assuming that once you (re)join a previously known network you can just go ahead and use it without further action. When the iOS device receives an error trying to use the network, it silently drops the Wi-Fi association.
If this is happening to you, follow these steps:
1) Go to Settings -> Wi-Fi
2) Select the network you want to join
3) When a check-mark appears next to the SSID, press the "i" button on the right hand side
4) Set Auto-Join however you want, but shut off the Auto-Login switch
5) Now attempt to use the network and you should be presented with the usual redirect page with terms you must accept or where you must login to use the Wi-Fi network in question
This cleared up the issue for me everywhere I had previously been having issues.

Just let me get one thing straight...you don't change don't do this for the PC you have your router plugged in to?
"For Vista:
1. Open Control Panel, Network and Internet, Network and Sharing Center, Manage Network Connections
2. If Wireless, Right click on your Wireless Network Connection, otherwise, Right click on Local Area Connection and click Properties
3. Highlight Internet Protocol Version 4(TCP/IPv4)
4. Click Properties
5. Tick Use the Following IP Address and enter the IP you want to use for that PC. I would start at 192.168.0.100(D-Link) and work your way up on each additional device. The second device would be 192.168.0.101, the 3rd, 192.168.0.102 and so on. Like I said, different brands of routers use different IP's, so it could be 192.168.1.100 and so on, so you will need to know the IP address of your router first.
6. Subnet Mask is 255.255.255.0 on all pc's and devices
7. Default Gateway is 192.168.0.1(D-Link) or whatever your router's IP is on all pc's and devices
8. Tick Use the Following DNS Server Address and enter 192.168.0.1(D-Link) or whatever your router's IP is and click OK.
9. You will need to do this on all Vista Pc's"

Network config requirement fails when installing Oracle 11gR1 on Windows XP

Hi
I am trying to install 11g on Windows XP Professional, I am getting
checking Network Configuration requirements ...
Check complete. The overall result of this check is: Not executed <<<<
Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP.
========================================================
In the installation log I can see:
Checking DetectIfDHCPAssignedIP
INFO: Checking DetectIfDHCPAssignedIP
This is a prerequisite condition to test whether the primary IP address of the system is DHCP-assiged or static.

INFO: Checking the network reference name..... :lo
INFO: Checking the platform .......912
INFO: Check complete. The overall result of this check is: Not executed <<<<
====================================================================
I installed Loop back adaptor and gave IP: 10.10.10.10 and subnet mask as : 255.255.255.0 .I added the entry 10.10.10.10 locahost in host file as well.
Could anybody tell me what is the problem?
Thanks
Praveena

I am able to resolve this by all network connections except Loop Adaptor connection and changing my computer name from LOCALHOST to HOME.

Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP.

Are you installing Oracle 10G R2? If this is the case then for DHCP network environments, you need to create a Microsoft loop back adapter.
Microsoft Loopback Adapter creation:
===========================
Step 1: Programs -> control panel -> Add Hardware.
Step 2: In the Add Hardware wizard. Click 'Next' and select 'Yes, I have already connected the hardware'. option and click on 'Next'.
Step 3: Select the last option 'Add a new hardware device' from the 'Installed hardware' window and click on 'Next'.
Step 4: Select the last option 'Install hardware that I manually select from the list (Advanced) and click on 'Next'.
Step 5: Select 'Network adapters' in 'Common hardware types' list and click on 'Next'.
Step 6: Where you can see 'Microsoft loopback adapter' on the right hand side of the frame.
Step 7: proceed with all default installation and then try installing Oracle.
I hope this will suffice.
Thanks

At home I have two wifi networks , I try to use one of them depending on their strength of signal, can I not save both their passwords on Apple TV , so that I can switch to one of the two wifi networks as required

At home I have two wifi networks , I try to use one of them depending on their strength of signal, can I not save both their passwords on Apple TV , so that I can switch to one of the two wifi networks as required
Also the passwords are long and cumbersome to type every time on the apple TV remote, what is the alternative if I cannot store them on the memory of the Apple TV

Is it possible that you are using the same password for the old O2 Study and newer O2 Apple Base Station networks?
If so, Keychain Access is storing the old information about the old network and may be associating it with your AirPort Extreme settings based on the BSSID that William has mentioned.
If that's the case, open Macintosh HD > Applications > Utilities > KeyChain Access and look for a listing with the old network name. Delete this entry. You may need to power down both the computer and the AirPort Extreme and restart them.

Error during Checking Network Configurations Requirements in RHEL3 VM

Hi,
I have a Red Hat Enterprise Linux Image Virtual Machine on my desktop which uses Fedora Linux. I have set this up using VMplayer.
I need to install Oracle 10g on the RHEL VM.
As the RHEL VM does not have X Windows, I am connecting to it from the Fedora Linux to do the installation.
During the Product-specific Prerequisite checks:
Checking Network Configurations Requirements throws an error,
Please find it below:
Actual Result: Unknown Host Exception has Occured :rhel3vm:rhel3vm
Check complete: The overall result of this check is: Not executed <<<<
Recommendations: Oracle supports installations on systems with DHCP-assigned public IP addresses. However, the primary network interface on the system should be configured with a static IP address in order for the Oracle software to function properly.
The Fedora Linux gets the IP address from the DHCP and allocates an IP address to the VM.
However, when we set both of them as static and the problem still persists, and also when we set the fedora as dynamic and RHEL VM as static, the issue is not resolved.
Any help will be truely appreciated. Thank you.

We were running a non-DHCP (static IP) configuration and ran into this issue. We discovered that the hostname and FQDN were not correctly specified in the /etc/hosts file.
Fixing the hosts file to correctly reference the IP resolved the issue.
Hope this helps...

WAAS Inline Network Adapter Required for 674 Appliance Inline Mode?

Is an Inline Network Adpater required to setup a WAAS 674 Appliance in Inline Interception Mode or can the two inbuilt interfaces Gi1/0 anf Gi2/0 be used?

Hi,
You definitely need an Inline Adapter to setup WAAS 674 for inline interception mode. The built in Gig interfaces cannot be used for inline interception but can be used for WCCP or PBR. Inline adapter comes in a group LAN port and a WAN port.

Kiran.

During installation all checks are passed but this one, is there any particular reason for this check not to be executed? Should I worry over it not beein executed?

I'm trying to install Oracle 10g 2 on a Red Hat 4 server with a static IP.

Hi!
Either your machine is setup to use DHCP after all or the installer just has trouble to find the correct information.
Recheck the network settings of your machine (redhat-config-network).
Just ignore the warning and continue.

Network configuration requirements 10g

hi every body
i am trying to install oracle 10 g db using Vmware on Centos 5.
i have performed all the steps as described in installation guides but when OUI is checking pre reqs it is giving this error
"checking network configuration requirements" and then "not executed"
can somebody please specify these requirements ???
in case i want to move forward it says that you can expect some problems during installation ???
thnx in advance .
Regards

do you have a network setup ? Can you ping other servers from the VM ?
You can run a database without a network. The listener configuration may fail, but you can easily re-run it later. You could just do the install, and see if anything else fails. If it does, the error may give more information.
Or you can turn off the check using
runInstaller -ignoreSysPrereqs

CHECKING NETWORK CONFIGURATION REQUIREMENTS : WARNING

Hello........
when I want to install oracle 10.2.0.1 software, there is warning about CHECKING NETWORK CONFIGURATION REQUIREMENTS
it is :

what can I do
tank you very much to help

I suggest you to read this thread: Re: I can't access to my Enterprise Manager. Then you'll realize why it is important to define a fixed IP Address and not to entirely rely on a DHCP dynamically assigned IP Address. This thread shows you how to configure a Loopback adapter to solve this issue.

Fiori Wave 2 Launchpad HTTP 511 Network Authentication Required

Dear expert,
When I try to call the Fiori launchpad, it returns the code of HTTP 511 Network Authentication Required. BEFORE the login screen shows.
Also error: GET /sap/bc/ui5_ui5/ui2/ushell/shells/abap 401 Unthorized.
However if I maintain the ushell service in SICF on LOGON DATA tab with a specific user A103296.
The homepage(with error "unable to load groups") comes out directly without the login screen.
For "unable to load groups", it says 401 Unauthorized for PAGE_BUILDER_PERS.
However I have both the authorization SAP_UI2_ADMIN_700 and SAP_UI2_USER_700 for A103296.
I suppose there's no need to maintain the logon data for SICF service,right?
On the other hand, Launchpad Admin screen runs smoothly without any issue.
Could you please help on this? Masayuki Sekihara
Thank you very much indeed!
Thanks,
Chloe

Hi Masa,
The issue is solved.
Because the customer's /bc/ui5_ui5/ui2 service logon ABAP class was changed from /UI2/CL_SRA_LOGIN to /IWFND/CL_COC_SYSTEM_LOGIN.
Change the class back to /UI2/CL_SRA_LOGIN and is able to log on to the launchpad now.
But cannot figure why this error message shows about "authentication".
Thanks,
Chloe
