TMS RFC using load balancing in HA system

Hello all,
I have configured the TMS in my system (report TMS_MGR_LOADBALANCING) to use load balancing while communicating with the QA and the PROD systems which are HA systems.
By default, the user group SPACE was used for the RFC. Is there a way to change the user group that the RFC uses?
Regards,
Oren

Hi Matt,
Thanks. I did read this note when looking for a way to change the logon group. Since I did not find there any hint how to change it, I thought maybe someone else already found a way without rewriting the report. Appearantly there isn't...

Oren

App.server load balancing for SAP System with 1 PS

Hi,
In SAP CPS 7.0 (Build M26.12) I have a SAP system with Central Instance + 10 App.servers, but all instances are managed by 1 ProcessServer.
After activating the "App.server load balancing" setting in SAP system definition the application servers are becoming visible in CPS with their load factors (number of BGD wp's on app.servers) and load numbers (number of active jobs on app.servers).
This is so far fine, but the additional functionality is not working as I would expect, I have issues with 2 functionalities:
1. Based on documentation after activating also the XAL connection the CPS should submit the job on app.server with best performance based on XAL monitoring data filling the TARGET_SERVER parameter.
This functionality is not working for me at all
2. A useful functionality after activating the "App.server load balancing" setting is that the ProcessServer is going to "Overloaded" status when all BGD wp's of SAP system are occupied, thus restricting submitting new jobs during overload situation. But I had an issue also with this functionality, after SAP system recovery from overload situation, the CPS still remained in Overload status (so no new jobs were submitted).
As a workaround I had increased the treshold values for loads on all app.servers for this SAP system, what was fine for several days, but after a while I believe this was a reason of unexpected performance issues in CPS, therefore I have deactivated the 'App.server load balancing" setting at all for this ProcessServer.
I would appreciate your feedbacks with this functionality.
Thanks and Regards,
Ernest Liczki

Hi Preetish,
This connect string option is to loadbalance RFC connections. These are balanced upon login, once you are connected to a particular application server (AS) you stay on that server until you reconnect.
Since CPS uses multiple RFC connections, this will result in the connections being distributed over the available AS resources which is fine as long as they are generally evenly loaded. If you have certain AS hosts that are continuosly more loaded than the rest, then you probably don't want the CPS RFC connections to end up on these servers.
The original question is about loadbalancing of batch jobs over the available AS resources, and this is done independent of the RFC connection load balancing. Even if all CPS RFC connections are pinned to the DB/CI host, you can still loadbalance jobs over the available SAP AS hosts, either by using SAPs builtin balancing, or the CPS algorithm by activating the checkbox as indicated in the first entry in this thread.
Finally, to reply to Ernest's question: I believe there are some fixes on the app load balancing in the latest release, M26.17 should be available on the SWDC now.
Regards,
Anton.

System Using Load Balancing

Hi gurus,
we have to do sso to ECC through portal
we have ECC system with three instance ,i am going for creating SAP System using Load Blancing,
what is the value of server port should i enter.
regards
K Naveen Kishore.

The server port is often maintained by system administrators on the local PC in the c:\windows\system32\drivers\etc\services file. The system server port is entered into the file as sapms<SID>.
Check the services file on your computer and see if there is any entry for sapms<SID>. If this entry is maintained, you can put sapms<SID> in your System properties.
You can also choose to enter the tcp port number of your application server or message server here.
The value is generally 3600 or 3601.
Check the following links also:

Windows 7: Service unknown when using load balancing group

I try to run SAP GUI 7.10 on Windows 7. I use a load balancing group to connect to the server. The direct access to one of our cluster nodes works ok, but when clicking the link to the load balancing group says "load balancing error on logon 88: connection to messaging server not possible (rc=9)" (translated from german).
What is happening here? It works good on Windows XP. Do I have to use another saplogon.ini or something?
Thanks for any help!

Is it ok to deactivate UAC in a company?
That's something your M$ group must decide.
It sounds like a good security feature but as we see here it´s a pain in the @$$ for administrators...
Well - the purpose of it is to disable the ability of malware and virusses spreading around. I consider it as a security breach if a local user is able to simply copy files to the operating systems main directory. A user working with a frontend PC should not have local administrator rights at all; all software requiring this badly designed.
If you use the SAPGUI installation server you can distribute services, saplogon.ini etc. using the installation server provided service without the need of users having to have local administration rights:
Note 512040 - Distributing "services", "saplogon.ini", and similar files.
I just think that "administrators" must learn to do work properly as designed with operating systems without just "copying files around" in system directories (and I don't exclude me in that context).

SmartView connections using load balancing

Is there a way to create a connection in SmartView to the Planning application that uses the load balancing functionality? When we log into the Planning web application we have a connection that provides load balancing between the 2 Planning servers. It appears that the only connection you can provide in SV for Planning is a direct connection to a web server like this: http(s)://<servername>:8300/HyperionPlanning/SmartView.

I did a second look at my configuration and it actually looks like Workspace is the only Smartview connection that I have load balanced. For Planning, once connected to the Hyperion Provider Service URL the Planning applications show under the Common Provider Connections. The Planning connections point to the URL of the APS.....which is just like what you use. http://servername:8300/HyperionPlanning/SmartView
Reading through the EPM High Availability Guide, it appears that it can be done for APS but it seems that might no longer support Planning:
The following list specifies supported clustering methodologies for EPM System product and components (with sublists for components) and options for removing single points of failure from the architecture and maintaining consistent performance through load balancing.
Oracle Essbase—Clustering with Oracle Hyperion Provider Services for high availability and load balancing
Note: High availability for Essbase with Provider Services does not support write-back.
See the Oracle Hyperion Enterprise Performance Management System Manual Deployment Guide.

Clustering with Provider Services
If Essbase is clustered with Provider Services and no third-party tool:
- Smart View must be used rather than an Excel add-in.
- Essbase has no write-back capability and should be used for reporting only; therefore, Oracle Hyperion Planning, Fusion Edition is not supported.
- Nodes must be loaded and calculated individually.

Error using load balancer in ebusiness suite R12

Hi
Has any one used Cisco 11503 load balancer in their ebusiness implementation
we have upgraded a customer instance from 11i10cu2 to 12.0.6. we have configured the R12 instance for load balancer as per metalink note 380489.1
when we access the ebusiness suite, we hit the issue as mentioned below:
You cannot complete this task because one of the following events caused a loss of page data. Possible Causes:
You have left your login session idle past the timeout period. A system failure has occurred. The application server is incorrectly configured and does not send a session cookie to the client browser. If you were testing in JDeveloper: JDeveloper OC4J process did not fully shut down before restarting the application. You closed one of the Internet Explorer browser windows while the request is being processed in another Internet Explorer window. Closing an Internet Explorer window causes OC4J to expire a user session. OC4J XML files in your JDeveloper user home system directory have been modified or corrupted.
as per many metalink notes, this may occur due to load balancer ..example note : 755825.1
we have then removed load balancer setting from the applications context file (xml file) and issue doesnt occur.
so issue seems to be with load balancer setting, however we couldnt find any doc which mentions setting for Cisco 11503 load balancer
we saw notes for Bigip and cisco ACE load balancer in metalink 601694.1
Customer is also unable to help here .. as to what setting needs to be changed
Can someone kindly advise

Have you opened a case with Cisco to see if they can help ? Has persistence been enabled on the load balancer ? Is there some kind of timeout enabled on the balancer ? I do not know much about load balancers, but the settings should be somewhat similar across all of them. See if these docs help

Load balancing across remote systems

Hi everyone,
When a request is routed to a remote machine (assuming that the service is not
available on the local machine) load balancing is based on the load factors (plus
NETLOAD, if set) of requests previously sent to the remote systems from the local
system. My question is: is the load accumulation ever reset? As I see it, a
reset could probably happen in one or more of the following ways:
1. A rolling time period that will cause earlier load values to be progressively
discareded.
2. The load accumulations are reset every time a system is booted.
3. The load accumulations are reset whenever the tuxconfig is modified.
4. The accumulations are reset when the tuxconfig file is removed and recreated
(I guess this is obvious, assuming this is where the accumulations would be stored
between boots).
The question is prompted by the following scenario. Machines A, B and C have
been configured to offer the same service, but the service has only been enabled
on A and B. Machine D does not offer this service, and therefore requests from
D will be balanced between A and B based on the accumulated load recorded on D.
This situation has been in operation for a couple of months without rebooting
(quite possible - after all, this is Tuxedo we are talking about!), and it has
now been decided to activate the service on machine C (without rebooting). The
big question is: Will all the requests be routed to C until such time as it catches
up to the load processed by A and B?
Thanks to anyone who can shed some light on this.
Regards,
Malcolm.

Where are you looking for the load accumulation?
"load done" with psr command?
In my case, with Tux 6.5, these stats are only reset with a reboot.

Relaying using Load Balancer

Hi
Two node Exchnage 2010 DAG. All server roles on the same boxes.
CAS high availability using Cisco load balancer.
We have some applications they are relaying using Exchange 2010 Hub. They are configured using the vip of the load balancer.
The problem is, that they are unable to relay to external recipients, internal is no problem. Using the Hub directly works fine.
What could be the problem?
Regards
Peter

For those who still monitor this thread,
The issue here is that the HLB is not configured to Use Source IP. In the Netscaler world, this is configured on a device or load balancer level and is referred to as USIP. (Use Source IP) If Source IP is not configured, the HLB will pass
the traffic to Exchange using the HLB's interface. You can configure this IP as an allowed IP address on your relay connector, but this is a big security risk as previously stated because all traffic that is routed through the HLB has rights to relay.
Concerning the network guy in PeterN22's post, open connections can be a problem and can cause port saturation if you are using an (*) as a wildcard on your RPC load balancing service. I have had much better luck, across all my load balanced deployments
(Citrix, Kemp, Cisco, etc.), when I use static port assignments on all load balanced services. For example:
SMTP - 25
RPC - 59532
OAB - 59533
HTTPS - 443
POP - 110
etc.
Exchange 2013 load balancing is now stateless and doesn't rely on Source IP, but this same issue with SMTP will occur if Source IP is not used. I know this is a recap of some of the other posts, but hopefully the additional information is helpful for
someone who may come across this post.

Errors when scheduling scenarios for agents using load balancing

Hi,
I have set up my ODI environment and have successfully manged to:
* run scenarios manually in development repository
* schedule scenarios and run on execution repository with one agent.
However when I try to set up a second agent to load balance the scenarios I get the following error below.
It seems to be a load balancing problem because I can run the scenario's successfully in every other case.
I am running an oracle RAC database. (2 servers, one oracle instance on each). I have set up one ODI agent on each server and I am trying to load balance between these 2 agents.
In topology I have set up 1 logical agent. Physical agent 1 is linked to itself and also to Physical Agent 2 under the load balancing tab.
For my scenario's I have 2 master scenarios (which are the ones scheduled) that call a number of other scenarios in the correct order.
Could anyone assist me please?
Thanks,
Matthew

Hi,
I'm wondering whether there may be a design flaw in the way our scenario's have been created / are executed.
Currently we have x number of scenarios executed by a x master scenario.
There are also y number of scenarios executed by a y master scenario.
These master scenarios are the ones scheduled against the agent and they call the "sub-scenarios".
We experience the above error when one of the "sub-scenarios" of a master scenario is executed on a different agent to where the master scenario is executed.
Any help greatly appreciated.

Even logon distribution using load balancing

We are trying to scale our system to distribute logons across multiple app servers. We have setup Logon groups and have set MSHOST in our connection configurations but since all logon's occur at roughly the same time, they all end up going to the same app server. We have 40 connections and ideally would want 20 to go to server A and 20 to go to server B, so that when each logon has work to do, the load gets evenly distributed.
We have tried modifying the threshold value for each app server in the logon group but that has had no impact.
Any suggestions?
Thanks
Tim

Tim
Logon group should work fine if there is difference in login time by at least 5 minutes.
SAP calculates the best server for dialog logon by determining the quality of a particular server. It gives weightage to number of users and response time of dialog in a ratio 5:1 and then calculates the quality of the server. This information gets updated in every 5 mins. User at a particular time are assigned to the best server ( according to quality).
When all the users are moving to the same server, you can check what is the quality of a particular server.
SMLG-->F5 ( Goto>Load Distribution) and SMLG--->F6(Message server status area). Check if the current logon instance is changing with time. If that is changing then your logon groups working...If not then then raise a OSS message to SAP.
Even if your logon grp working but you are unable to get the advantage,
you can set up multiple logon group with different app server. Like GRP1 will have App1, APP2 then GRP2 will have App3, App4 and so on and then ask your user to use different logon grp.
One more thing, what is the auto_logout setting is your system? if users frequently login and then after work log off they can get the best effor in terms of logon group.
Waiting for further details from you

How to configure TMS landscape using three clients of same system?

Hi All,
I have to design a prototype for linking satellite systems to Solution Manager. To work on the Change Request Management module of Solution Manager.
Here, I need a Development - Quality - Production landscape to be configured to link it to Solution Manager, but I have only one system available to do this.
I have the clients 410, 420 and 430 in the system XYZ. Now, how do I simulate the three system landscape in STMS for the three clients mentioned above.
I tried using many attempts, but it is not working out. I could figure it out that this is possible by activating "extended transport control" parameter for each system, in STMS.
Also, there are some specific needs to configure this landscape for linking to Solution Manager, the comments are shown below:
"Transports are supported in the standard transport layer of each client. When you configure transport routes, note that only consolidation routes that are assigned to the standard transport layer of the relevant exporting client are taken into consideration. For each exporting client, exactly one target client and one target group are permitted.
We recommend that you assign exactly one development system to a production system, and that these two systems are connected by exactly one unique transport track.
If a development system and a production system are connected by more than one transport track, this may lead to inconsistencies within the transport distribution.
This type of transport configuration cannot be supported by Change Request Management, and may cause inconsistencies within the tools involved."
Please suggest me, as how to proceed to configure STMS for the same.
Thanks in advance.

RFC Sender (XI 3.0, SP14) Load Balancing doesn't work

Hi all,
We're "desperately" trying to use the Load Balancing option of RFC Sender Adapter (XI 3.0, SP14). It doesn't work.
The Adapter can not register to the sender SAP server. But when we do not use the "Load Balancing" option, everything works well.
We did follow the XI guidelines step-by-step. All necessary configurations in XI and in SAP sender system (TA: SM59) are "properly" done and reviewed by different experts several times.
Do you have, by chance any running scenario using "Load Balancing" within a RFC Adapter? If yes, I would appreciate if you can share it with me.
Thanks a lot!
Regards,
Khaled

Hello Khaled,
the RFC sender adapter registers a program at the SAP Gateway. Load Balancing for the Sender Adapter means, that you have at least two J2EE server nodes within your XI installation. On all these server nodes the same RFC sender adapter is started and register the same program at the same gateway. The load balancing is then handled by the gateway. That means, that for the sender adapter the settings are the same, even if you use load balancing or not.
The settings are, e.g.
- SID=ABC
- hostname=abchost (central instance, message server)
- hostname=xyzhost (additional dialog instance of ABC)
- instance nr=00
application server (gateway): xi1host
application server service (gw-service): sapgw00
programm id: could be freely choosen
The Metadata Repository could be connected using load balancing. Here a user need to log on to the system.
The settings here must be:
Message-Server: abchost
Message-Server-Service: sapmsABC
System-ID: ABC
Logon-Group: e.g. PUBLIC; this logon group need to be created in system ABC using transaction SMLG
For the RFC-Receiver Adapter the same settings as for the Metadata could be used.
Keep in mind, that for the RFC Sender Adapter a RFC connection of type T must be created in transaction SM59 in system ABC.
Rgds.,
Andreas

Load balancing and rfc metadata repository in reciever rfc communication ch

hi.
i want to know the purpose of load balancing and rfc meta data repository in RFC communication channel.
and can u send me any examples on this load balancing.
waiting for your response.
bye.
regards.
seeta ram.

Hi Seeta Ram,
Load distribution is handled by the message server (there is one message server in an SAP System). When a user logs on, the message server assigns him or her to the application server that currently has the <b>smallest load</b>.
Well now you can understand that we use load balancing for better performance by distributing the work to different processes to balance or maintain the work load in SAP system.

Using the load balancing on SAP

Hello,
wa have different SAP job chains using ABAP scripts and we would like that this scripts use the SAP application server because they run under DBCI and this is not correct.
We found that the SAP script use a specific "execution target". This should not be so. The execution target should be blank for using load balancing.
In the init jcs file, the parametetr "sheduler_hostname" and "sheduler_fqdn" are positionned with the hostname of the Redwood SAP Agent. Should this be modified ?
thanks.

Hi,
It looks like you have Load balancing enabled from CPS (it is enabled by default). To switch of load balancing go in the Redwood registry in the Redwood Explorer (Configuration->Environment->Registry->PUBLIC->RSI-><SAP instance>) and look for the value at parameter LoadBalancing. You can switch this of (set to N) and restart the RFC agent for this instance. Now the execution target will be left empty.
