What SSL accelerator and load-balancer does anyone recommend?

Hi:
I wanted to find out:
Does anyone recommend SSL accelerator cards/boards or SSL accelerator appliances?
What SSL accelerator and load balancer does aynone recommend to help 9iAS?

Hi there!
I just downloaded and installed OS X Lion, and I'm loving it so far.
However, I've seen that Mountain Lion will have some new features when it comes to social apps (what I call the ones that combine twitter, facebook, rss readers and so on).
So, does anyone knows any cools apps for that? I'm currently using Socialite, that combines all those three, but it has a few issues I don't particularly like. Plus, I'm using Adium for a msn client. I'm also thinking about downloading that beta version of "Messages" that will be realeased on Mountain Lion.
So, what do you think? Give me your ideas
Thanks a lot in advance!
As Mountain Lion has not been released to the public yet, then most of us have no idea which companies have updated the development of their Apps for ML. It is in Development phase so any App you try is at your own risk.
Good Luck

What does per Wlan Band select and load balancing do ?

Good morning.....We recently upgraded our controllers from 4.2.185 to 6.0.188 and have noticed many clients having connectivity issues. We have Aggressive load balancing turned off globally but have noticed that band select and load balancing are enabled on the
Wlan. Are these settings mutually exclusive or do they do the same thing ? Does the Wlan setting override the default ? We have noticed that there is
output doing "debug dot11 load-balancing"
Thanx.....Dave

I believe we never had load balancing turned on when running 5.2 code. We jumped from 5.2 to 6.x temporarily and then to 7.0 within a 30 day time frame this summer. We're a large university and we had very few users on WiFi during that time.
The Macintosh laptops are having nothing but trouble since school began, and I have gone over everything and found that band select is turned on as well as load balancing. Since band select didn't exist in 5.2 (I believe) I know it wasn't on. As for load balancing, I don't believe it was on, and I discovered it was turned on when recently reviewing our configs.
The Macintosh laptops have been debugged and our Mac gurus tell us they're getting a message that equates to "the AP is busy, or the AP is full". This leads me to believe that load balancing got turned on during the upgrade and we didn't notice, which caused the Macintoshes to have issues.
We don't have any VoWiFi clients so we don't have to support them, and we don't officially support smartphones, either.
I turned off load balancing and will see how it goes....
Thanks!

I've been working on our church website and suddenly, my computer will not connect to the site. I keep getting a message saying that the the connection to the server was reset while the page was loading. Does anyone have any ideas of how I can fix this?

I've been working on our church website and all of a sudden this week, my computer will not connect to the site. I keep getting a message saying that the the connection to the server was reset while the page was loading. Does anyone have any ideas of how I can fix this?

The "The connection was reset" error message can be caused by a bug fix for the BEAST (Browser Exploit Against SSL/TLS) attack that the server doesn't handle.

Oracle Applications 11i Load Balancing does not work with RAC one Node

Hi all,
Could you help me to resolve this issue.
Architecture environment is :
- One APPS tier node
- Two nodes Oracle Database Appliance (Primary node 1 holds INSTANCE_1 et Secondary node is configurured to holds INSTANCE_2), i.e RAC one Node.
- The primary node have instance_name SIGM_1 and the secondary node have instance_name SIGM_2, but in RAC one node, the secondary instance is not alive.
We convert our EBS 11i environment to RAC following note ID Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 11i [ID 823586.1].
When testing Database failover, Oracle Applications 11i load balancing does not work anymore.
The root cause is that, when the primary node of the Rac one node is down, the INSTANCE_NAME_1 is automaically relocating to the surviving node,.
During test failover, we imagine that when the primary node goes down, the secondary node start or relocate database with instance_name SIGM_2, and in that case the Oracle Applications load balancing works.
Currently, when the primary node goes down, the instance_name SIGM_1 is relocated on the secondary node, which cause failure of Oracle Applications Load Balancing.
Thank you for your advice.

This is something I observed a long time ago for Safari (ie: around version 1). I'm not sure this is Safari, per se, but OpenSSL that is responsible for the behavior. I'm pretty sure Chrome does this and I've seen some Linux browsers do it.
What I have done at the last two companies I've worked for is recommend that our clients do not use SSL SessionID as the way of tracking sticky sessions on web servers, but instead using IP address. This works in nearly all cases and has few downsides. The other solution is to use some sort of session sharing on your web servers to mitigate the issue (which also means that your web servers aren't a point of failure for your users' sessions). (One of the products I supported had no session information stored on the web servers, so we could safely round-robin requests, the other product could be implemented with a Session State Server... but in most cases we just used IP address to load balance with). The other solution is to configure your load balancer to terminate the SSL tunnel. You get some other benefits from this, such as allowing your load balancer to reduce the number of actual connections to the web servers. I've seen many devices setup this way.
One thing to consider through this is that - due to the way internet standards work - this really can't be termed a bug on anyone's part. There is no guarantee in the SSL/TLS standards that a client will return the same SSL Session ID for each request and there is not requirement that subsequent requests will even use the same tunnel. Remember, HTTP is a stateless protocol. Each request is considered a new request by the web server and everything else is just trickery to try and get it to work the way you want. You can be annoyed at Safari's behavior, but it's been this way for over 5 years by my count, so I don't expect it to change.

Data Centre Interconnection - firewall and load balancer deployment

Hi all,
I've read lots of Cisco docs/white papers on DCI - Layer 2 extension between DCs, but as yet I cannot find any decent information on how best to deploy firewalls and load balancers in such a design. I've seen refs to FHRP isolation on Nexus 7k (and possible 6k if you use DCI block) but nothing on the services elements.
The services element seems to be a complete minefield here:
- active/standby across sites, or deploy resilient pairs in each site?
- how to align optimal traffic flows inbound and ooutbound (RHI, SNAT, etc.)
- best practice suggestions ideally.
Cisco DCI docs seem to always gloss over the fact that most customers would have to deal with firewalls and load balancers here, and simply refer to 'coming soon' for that info.
If anyone has any good suggestions/links to docs explaining detailed implementation info would be much appreciate
Thanks
Phil

Reverse Proxy plug in and Load Balancer Plug in

Hi,
Can anyone please provide me with an example obj.conf file showing how to combine the reverse proxy plug-in and Load Balancer plug-in.
I would like to use the reverse proxy plug in to detect when static content is requested and provide this from the web server. Requests for dynamic content would then be forwarded to an Application server via the Load balancer plug-in. I have found plenty of documentation on how to configure these plug-in separately but nothing on how to combine the two.

smiking
reverse proxy plugin - its job is to forward the requests to another server for a specific task. you can use the webserver 7 . it does forward and limited load balancing (using round robin ) based on the number of servers you provide in the configuration. i would say this is a poor man's setup.
load balancer plugin - some app servers like sun java system app server or web logic provide this plugin so that you can effectively use the back end app server
with both these setup, you can <if> constructs to determine which requests need to be forwarded to the back end server.
I wonder, why do you need both - if both of them is designed to do the same thing.

Web Dispatcher - Reverse Proxy and Load Balancing

I'm finding limited docs on Web Dispatcher with regard to reverse proxy and load balancing. Are you aware of some recent presentations or docs in this area? The info on help.sap.com is not what I'm looking for.
Thanks.

Hi,
best thing is that you look at your scenarios and test the web dispatcher against each of it, like:
- SSL
- Portal only
- Web Dynpro ABAP / Java
- BSP
- Different backend systems like SRM, MDM
- Several backends with 1 Web Dispatcher
After getting a list of use cases that you can test quite easily (installation of Web Dispatcher is done fast and can be done on a local PC), you can contact SAP Support and ask them about the specific problems and questions you encountered. This way, you'll get the official answer, sometimes they will even inform you about "secret" parameters and options.
As of the reverse proxy functionality: there are several version of Web Dispatcher available that differ from the functionality offered. The latest version - 7.2 - is the one that offers the most, i.e. allows you to create rewrite rules like Apache.

How to remove farm account from Application Discovery and Load Balancer Service Application

Hello Community
    Using Sharpoint 2010 Server I think the reason
the User Profile Synchronization would stop is because somehow the farm
account was registered as a managed account. So I removed the farm
account from all services that ran under the farm account so that I could
run Remove-SPManagedAccount or click the Remove icon in manage service accounts
and then unregisted farm account as a managed account.
   But before I can run Remove-SPManagedAccount I need to remove it from one more
service account that uses the farm account which is:
    "Application Discovery and Load Balanceer Service Account".
    However, nothing seems to remove it from there.
    I tried :
"get-spserviceapplication | where {$_.TypeName -match "Application Discovery and Load Balancer Service Application"}
    and then
"stop-spserviceinstance "dde7fbef-b068-4687-bedb-f67230efab5a"
    amongst a host of other methods so that I could ultimately
unregister farm account as a managed account.
    But no matter what I do when I try to remove the farm account from Application Discovery
and Load Balancer Service Application
and then unregister the farm account as a managed account a message always says
"Application Discovery and Load Balancer Service Application" is using the farm account
as its service account.
    What can I do to free the farm account from Application Discovery and Load Balancer Service Application?
    Thank you
    Shabeaut

The Farm Account is always a Managed Account and can never be "unmanaged". You don't have to set the automatic password roll.

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application

Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance
g.

PIX Redundant Internet Line and Load balancing

I would like to find out if it's possible to configure my Cisco PIX 525 to use a secondary internet line from a different provider and perform load balancing. I'm using PIX Version 6.3(1)

PIX version 6.3 does not support Redundancy and load balancing. but PIX/ ASA with version 7.0 supports Redundancy.

VPN device with dual ISP, fail-over, and load balancing

We currently service a client that has a PIX firewall that connects to multiple, separate outside vendors via IPSEC VPN. The VPN connections are mission critical and if for any reason the VPN device or the internet connection (currently only a T1) goes down, the business goes down too. We're looking for a solution that allows dual-ISP, failover, and load balancing. I see that there are several ASA models as well as the IOS that support this but what I'm confused about is what are the requirements for the other end of the VPN, keeping in mind that the other end will always be an outside vendor and out of our control. Current VPN endpoints for outside vendors are to devices like VPN 3000 Concentrator, Sonicwall, etc. that likely do not support any type of fail-over, trunking, load-balancing. Is this just not possible?

Unless I am mistaken the ASA doesn't do VPN Load Balancing for point-to-point IPSec connections either. What you're really after is opportunistic connection failover, and/or something like DMVPN. Coordinating opportunistic failover shouldn't be too much of an issue with the partners, but be prepared for lot of questions.

I was using photoshop CC as normal, when suddenly it started going haywire. It has corrupted all the one PSD files by distorting the images and colour. Does anyone know how to recover the original images?

I was using photoshop CC as normal, when suddenly it started going haywire. It has corrupted all the open PSD files by distorting the images and colour. They are now completely unrecognisable and unusable. Does anyone know how to recover the original images as I was saving them as I went along but the files are now corrupt?

What version of Photoshop are you running?
I've seen a couple of instances over the last week or two where Photoshop has added masks, strange colours and also merged content from two separate PSD files that were open at the same time.
This has occurred on two different iMacs, (both 10.10.x) running Photoshop CC 2014.2.2 (20141204.r.310 x64).

Difference between Clustering and Load balancing

          What is the difference between Clustering and Load balancing?
          For example, We use Cisco Arrowpoint to do load balancing and it works fine for 3
          Sun solaris boxes/WebLogic 6.1 SP1.
          So what is the value addition to buy clustering license?
          Thanks
          Selvaraj


Hi.
          Among other things, clustering allows you to share app data (such as http session
          data) across cluster members, allowing you to failover should one cluster member
          crash.
          If your app is stateless then this doesn't mean much - load balancing alone would
          probably be ok for you.
          Regards,
          Michael

Resources for designing redundancy and load balancing among data centers

Hello all,
I'm looking for resources for designing redundancy and load balancing between two physically separate data centers. I'm looking for some "best practice" links, tips, or recommendations. Any suggestions are appreciated!
Thanks.

I think that we can do per packet load balancing by using CEF.
Please go to the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fswtch_c/swprt1/xcfcefc.htm#xtocid5
Also, you may need local director or distributed director. What resource/application is availalbe in the data centre? (e.g. http server, ftp server, TN3270 server, and so on)

What SSL accelerator and load-balancer does anyone recommend?
