TCP SYNSEEN with load balancing Cisco ACE 4710

I have a Cisco ACE 4710 load balancing the traffic to two proxy servers, the configuration is the same since December 2012, but yesterday it stated to show SYNSEEN in the show conn command, and the hosts cannot browse. I think that means that the three-way-handshake is not complete.
If I bypass the ACE the hosts can browse without problems.
I have tested with another ACE appliance and the same configuration but the behaviour is the same.
I need help as soon as possible,
thanks,
I've attached the Show conn, show conn detail and show run.

Hi Cesar,
Thank you for your answer,
The issue was solved,
We were running an A3 software version, it seems to have a Bug so it doesn't show the NAT commands in the "show run", so when we made the configuration backup we didn't noticed it.
The ACE reloaded because an electrical failure so it losted the NAT config.
We just upgraded to an A4 version and also added a NAT/PAT to enable the communication between the Clients and the Proxy.
Regards,

Problem with load balancing on ACE 4710

Hello.
I'm setting ACE4710.
I'm using DSR (Direct server return).
The load balancing cannot be distributed now.
I append the network configuration.
Could someone please help out?
THANKS!

Hello.
My problem has not been to have load balancing to rserver.
Connection is http://192.168.11.100:9080/ → ＮＧ（Connection error)
Connection is http://192.168.11.101:9080/ → ＯＫ（rserver1)
Connection is http://192.168.11.102:9080/ → ＯＫ（rserver2)
Even if "predictor ROUNDROBIN" is changed, it is the same.
Why cannot load balancing be done?
It is displayed that State is OPERATIONAL as a result of doing 'show rserver'.
Is this a correct display?

FTP Load Balancing on ACE 4710

Hi,
I have two ACEs working in ROUTED-MODE. In the servers there are HTTP content and FTP content.
- The load balancing is working in correct form.
Now, I have a problem: The client wants to performs a FTP request to server in Internet from server belong to server farm configured in the ACE.
In simple words, now the server belonging to the farm will be the client for the FTP server in Internet. The client can connect to the Internet FTP, he enter his username and password, but when he want to transfer data (command as ls, get, put) the connection is closed.
- When the client makes the FTP comes with the VIP address 200.29.72.226 to the intenet FTP.
- I have a capture when is performing the command "ls" and the connection was closed: The ACE stated:

I atached a diagram of situation and actual configuration.
I appreciate your help
Thanks and regards,
Jaime.

Thanks Gilles!
I applied the commands you told me. I performed laboratory tests and it worked fine.
Then I apply in the ACE of client and the results were positive.
Thanks you very much again.

Send Email issue using "Mail Server Load balancer" (Cisco ACE 20)

I have asked this question in SAP MII forum too but it appears issue could be in NetWeaver Mail API. Please let me know if someone have experienced this kind of issue or any suggestions.
The send email action was working file in MII with smtp mail server on port 25. Recently basis did a change in mail server ip address and they installed a new Load Balancer . The Load balancer is between SMTP and MII. After this change MII does not send email (unknown source error). now MII send email action has ip address or qualified path of Load balancer in MII send email configuration instead of direct ip address of SMTP server. Below is the error message in Net Weaver logs.
MII still sends email if direct ip address of email server provided instead of Email Load balancer but not through Load balancer .
Any suggestions ?

Hi Ahmed,
I don't have experience with Blackberry, but, as the document mentions, the first thing to do would be making sure that the connection timeout is set to something high enough
You can find more details on how to modify this value at the link below:
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/vA2_3_0/configuration/security/guide/tcpipnrm.html#wp1074289
I hope this helps

Setting up additional load balancing on ACE 4710

I recently deployed ACE 4710 to load balance traffic to a group of web servers. I would like to add additional server farm(s) with different applications on them to ACE 4710 for load balancing the traffic. How can I best achieve this goal? I currently use 3 interfaces out of 4 interfaces (Server Side interface, Client side interface, and Failover interface). Do I need to use my last interface to set up for the new VIP address for a new server farm? Is virtualized service a possible solution? Thank you in advance.

You can configure trunking so that multiple vlans can exist.
Also note that the vip ip address does not have to belong to a subnet.
You could configure a static route on the upstream router pointing the traffic for the new vip to the interface ip address.
Gilles.

Need help to Configure Cisco ACE 4710 Cluster Deployment

Dear Experts,
I'm newbie for Cisco ACE 4710, and still I'm in learning stage. Meanwhile I got chance at my work place to deploy a Cisco ACE 4710 cluster which should load balance the traffic between two Application Servers based on HTTP and HTTPS traffic. So I was looking for good deployment guide in Cisco SBA knowledge base then finall found this guide.
http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_DC_AdvancedServer-LoadBalancingDeploymentGuide-Feb2013.pdf
This guide totally fine with my required deployment model. I have same deployment environment as this guide contains with ACE cluster that connects to two Cisco 3750X (Stack) switches. But I have some confusion places in this guide
This guide follow the "One-armed mode" as a deployment method. But when I go through it further I have noticed that they have configured server VLAN as a 10.4.49.0/24 (all servers reside in it) and Client side VIP also in same VLAN which is 10.4.49.100/24 (even NAT pool also).
My confusion is, as I have learned about Cisco ACE 4710 one-armed mode deployment method, it should has two VLAN segments, one for Client side which client request come and hit the VIP and then second one for Server side. which means besically two VLANs. So please be kind enough to go through above document then tell me where is wrong, what shoud I need to do for the best. Please this is an urgent, so need your help quickly.
Thanks....!

Dear Kanwal,
I need quick help for you. Following are the Application LB requirements which I received from my clinet side.
Following detail required for configuring Oracle EBS Apps tier on HA:
LBR IP and Name required to configure EBS APPS Tier (i.e, ap1ebs & ap2ebs nodes)
Suggested IP and Name for LBR:
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm detail for LBR Setup
Following detail will be use for configuring the LBR:
LBR IP and Name :
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm Detail for LBR setup:
Server 1 (EBS App1 Node, ap1ebs):
IP : 172.25.45.19
Server Name: ap1ebs.xxxx.lk [ap1ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Server 2 (EBS App2 Node, ap2ebs):
IP : 172.25.45.20
Server Name: ap2ebs.xxxx.lk [ap2ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Since my client needs to access URL ebiz.xxxx.lk which should be resolved by IP 172.25.45.21 (virtual IP) via http (80) before they deploy the app on the two servers I just ran web service on both servers (Linux) and was trying to access http://172.25.45.21 it was working fine and gave me index.html page. Now after my client has deployed the application then when he tries to access the page http://172.25.45.21 he cannot see his main login page. But still my testing web servers are there on both servers when I type http://172.25.45.21 it will get index.html page, but not my client web login page. What can I do for this ?
Following are my latest config :

Error in creation of JCO with Load balancing server

Hi,
We are using a ABAP user base for our WEBAS server 6.40 (with ABAP+JAVA). i have created a Public group in concerned ECC 5.0 system. I have already configured SLD, and then i maintain data supplier bridge in SLD and run RZ70 in ECC 5.0 system to load system information.. i can see details in SLD ..
now i am trying to create JCO connections .. here i am unable to create JCO with load balancing option.. i get
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=<servername> GROUP=PUBLIC R3NAME=SID MSSERV=sapms<SID> PCS=1 ERROR service 'sapms<SID>' unknown TIME Fri Jun 16 12:41:20 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 505 DETAIL NiPGetServByName2: service 'sapms<SID>' not found SYSTEM CALL getservbyname_r COUNTER 1
i am able to create single server JCO, but it fails in load balancing.. is there anything i have missed out in settings...
Thanks and regards,
Sudhir

Thanks, Bogdan Rokosa
I have the same problem,and solved it following the steps provided by Bogdan Rokosa :
you must insert an entry for your R3 system
(like: sapms<SID> 3600/tcp)
in services file
(C:\WINDOWS\system32\drivers\etc\services) on Java WAS.
I test the Jco successful without restart J2EE Engine.

Trouble in a SAP system with load balancing

Hello masters:
I had a trouble with workitems that came from a SAP system with load balancing. They doesn't receive the workitem ID in the UWL.
I created another system in the portal as a "dedicated application server", and made the necessary configuration in order to replace the first one, and then my workitems worked fine.
However, I would like to know what appened with the first system created as "system with load balancing". Why this system didn´t pass the workitem ID to the application (web dynpro abap) that execute the workitems?
Thank you.

I hope there was some missing configuration in the first case which was not replicating the workitem from SAP Inbox to UWL.
Thanks

System with load balancing server

Hi All,
We are having SAP NW 7.0 Portal and back end we have R3 implemented in a cluster environment. The system object in EP have used "System with Load balancing" template; using the LOGON group and the other related parameters.
But we have some problem with the ITS and WAS parameters; since we are using some Transaction iViews.
Let me explain.. for the R3 cluster we have 2 systems PROD1.domain.ext and PROD2.domain.ext. Now in the system object in portal, how to specify the parameters for ITS and WAS parameters? Since the host name in these we need to specify a single server which defeats the basic purpose of having clustered environment.
Can any one please help in resolving this issue.
Thanks,
Sravanthi

Hi Sravanthi,
Please check the below for finding ITS and WAS parameters from backend :
For ITS - Go to SE37 >> Utilities >> Setting >> Click on ICON Right Top Corner in popup window >> Select Internet Transaction Server >> you will find the Standard Path and HTTP URL.
For WAS - Go to SE37 >> Run FM - RSBB_URL_PREFIX_GET >> Execute it >> you will find PRefix and PAth paramter for WAS.
Please refer to this may help step-by-step : How-to create a portal system for using it in Visual Composer
Hope it helps

HTTPS with load balancing

Hi guys,
We have a portal system with instance 08, so we typically connect to the portal using port 50800 for HTTP, and 50801 for HTTPS.
We have just created a second server node for this portal (in the config tool).
When we connect to 50800, does this automatically load balance the user to the better server? From some reading on these forums, it seemed to indicate that load balancing will only occur if I connect using port 8109. (where 09 is the instance number for the SCS of our portal)
When connecting to port 8109, we are redirected to port 50800, as I'd expect.
Question 1 - do we need to use 8109 for load balancing, or can we still use 50800?
Question 2 - If we need to use 8109, which is a HTTP port, how can we achieve load balancing with HTTPS. Is there a different port we need to use to have HTTPS with load balancing?
Question 3 - Is the creation of a second server node the best way to accomodate additional users and load on the portal system, or is there a better way to do things?
Thanks,
Michael.

Better late than never.
The load balancing you describe through the message server has its limitation. It redirects you to one of the dialog server hosts which means that any bookmarks will always point directly to a dialog server which may be down at that moment.
Access directly to a dialog server on port 50800 will sort of load balanc on the java server instances that are on that server but not on other servers.
The general recommendation is to setup an external loadbalancer and SAP Web dispatcher is a good match if the load is not very high. SAP webdispatcher will then bind up the cluster address and act as a proxy towards the dialog servers of the portal. The user will therefore only see one address. This will also work for HTTPS.

Moving SMTP server to Azure with Load balancer

How to
move SMTP server to Azure with Load balancer???

Hi TechM,
Base on my experience, Windows Azure Platform does not provide out-of-the-box mail server (neither SMTP nor POP3). You could use SendGrid to sent mail. About this issue, I recommend you could refer to
http://stackoverflow.com/questions/10631585/email-sending-approaches and

How to configure R/3 System with Load Balancing?

Hello,
I've created a Web DynPro Application and I would like to case an iView on it. According to SAP tutorials I first need to configure an R/3 System with Load Balancing.
My problem is how to configure the "WAS Host Name".
According to the tutorial:
WAS Host Name = <host>.<domain>:port (this corresponds to the Web Dynpro server location and the port on which it is running eg. PXYZ.wdf.sap.corp:50000.)
I am using NW 04 and my portal is running on this address:
http://ep6sp9test:50000/irj/portal
When I set the WAS Host Name to ep6sp9test:50000 the Test connection fails (I have privildges and created an alias and User mapping). What should I put at this field then?

Hi
I think you have to specify the HTTP port og the WAS running the R/3 system. The 50000 port is the HTTP port of your portal - not the R/3 system. You can see the HTTP port of the R/3 system using transactioncode SMICM - services in the R/3 system.

Recommended configuration for load balanced Portal with load balancer, multiple gateways and multiple servers.

Does anyone have a recommended network, hardware and software configuration guide for a Portal installation running with multiple gateways load balanced (ie one URL) that talk to multiple servers?

David,
We've used Resonate (software) to load balance the gateways. It allows
you to group all the gateways under 1 virtual URL and load balance the
incoming connections over each gateway depending on the rules that you
define in Resonate. Look in the SUN portal whitepapers there is one that
talks about it specifically.
As far as load balancing the calls to the portals, the gateways will
automatically load balance across all the portals that they know about
using a simple round-robin rotation. You may be able to use Resonate in
front of the portals but you may need to activate persistance within
Resonate to ensure that the user always ends up on the portal that he
established his initial connection on (if you want that), check with Sun
on this one.
