Adapter Framework Load Balancing

Hi guys,
I lately read in SAP Doc "Performance Tuning In XI", there it is said that
Adapter Framework uses HTTP Load Balancer for Load balancing (Adapter Framework inbound processing using HTTP load balancing.)..
Can u put some light on the above statement?
Does it mean that the messages going out of Adapter Framework will use Load Balancer or messages coming inside Adapter Framework?
Thanks,
Ashish

Adapter Engine Load balancing for Messages HTTP SOA/SOE

Greetings all,
We are currently implementing our SOE/SOA solution utilizing SAP services between a .Net Application. Basically .Net -> PI -> ECC and back.
We are load testing the system and are now experiencing the CI getting overloaded.
We have upped the Thread Count (Thread Manager 350 and System Threads 120) and the Queue thread from 5 to 20.
We are using SOAP with Principal Propagation.
There is a hardware load balancer we are using which can spread the load between multiple application servers. We modified the SLDRegistration host and ports (http/https) in Visual Administrator (SAP XI AF CPA Cache) in the global server node.
In SXI_CACHE Got -> Adapter Engine Cache, it displays http://<sidms>:<port>/MessagingSystem/receive/AFW/XI
Is this where the load balancer should be placed with the port name?
Any help would be appreciated.
Thanks

Adapter configuration & load balancing

Hi,
I posted questions for my requirements on Adapter forum but did not get any answer.
Hope this forum can help.
We started a POc with Oracle As adapters for EBS. As part of that we are trying following taks,
1) Connect to multiple EBS instances & deploy individual adapter for same on AS
2) Use these two instances for loadbalancing & scalaing
I am not bale to find information about above two in Oracle Adapter documentation.
I could build sample EBs adpater scenario with concurrent programs and use a default APPS adapter deployed on AS server by modifying oc4j-ra.xml. But failed to delpoy multiple instances that can be viwed from Enterprise Manager.
Also how to configure my adapters for better load balancing and sclaling. Is there any doc link that i can read?
Thanks in advance.

Hi,
check out these:
1) SM59 - test connection
2) look all the parameters of Receiver RFC adapter configuration
Proper authentication details etc
3) Save the RFC adapter channel and activate the same
4) Refresh the cache for the Adapter metadata. Go to Integration BuilderAdmin>Cache Overview-->Directory -->Adapter Metadata
5) Probably the problem may be becuase of RFC Adapter is not active. Restarting the RFC adapter at J2EE admin level may solve your problem
Hope this helps,

Load balancing Central Advance Adapter Engine

Hello All,
I am trying to get more information on load balancing Central Advance Adapter Engine for SAP PI 7.1. How do I configure and load balance Advance Central Adapter Engine to handle more volume? Should I added extra non-central adapter engines to achieve this? If yes, How do I do this i.e. configuration etc? If not, then what is the best practice on load balancing the Central Advance Adapter Engine?
Thank you for replying,
Mayur

Hi,
I just post your Q&A here.
Cheers,
Aaron
I have few follow up questions regarding your answers.
1. For options 1 and 2, could you elaborate or point me some documentation on sap.help or somewhere else which talks more about these options?
   =========================================
   Basically you have more power with more processes (Instances or Server node) to process your messages in the Adapter Engine. That's the way to improve the system throughput.
   For more information, please refer to SAP PI tuning guide (I could not find the guide for 7.1, but the principle is still the same)
   https://websmp102.sap-ag.de/~sapidb/011000358700000592892005E.PDF
=========================================
2. For option 3, add non central adapter engine and configure scenarios.
    1. So, do I have to run non-central adapters on separate servers?
   ====================
    Yes. It is recommended to run non-central adapter enging on separate server to minimize the reciprocal impact in terms of resource contention.
   ==============
    2. Do I need web dispatcher to do the load balancing between central and non-central adapter engine?
    ========
    No. this is also not possible since the below is true.
    =========
I somehow think that if I am selecting the non-central adapter engine when creating the communication channel then it won't be "load balancing" because I will be sending a particular interface to the non-central engine at design time instead of runtime.
Thank you for taking time and replying to my questions.

IDOC Adapter error while load balancing

Folks,
I am facing an issue when I am switching on Load balancing button in RFC destination while sending IDOC in sender system . The sender system shows this error in SM58
IDoc adapter inbound channel: Error Error when rea
Thanks,
Manish

Hi Manish...
This is from F1 on Traget host field in SM59..Check part in bold..
Name of target host
 Name of the target host as displayed by the UNIX command 'hostname'.
 If you are using load balancing, the target host must be the host name
 of the message server of the SAP System. This is defined in the profile
 parameter 'rdisp/mshost' of the target system. If you have any further
 questions, consult your system administrator. 
 You can specify host names as
 - Normal host names
 - Host names in DNS format (if DNS available)
 - IP addresses
 - SAProuter names (in the form /H/.../S/.../H/.../S/... )
Notes
 If you enter the host name (for example, hs0311) as the target host in
 an RFC destination, its IP address is stored internally in the database
 table RFCDES (destination administration). This speeds up the RFC
 connection initiation, since the host name does not need to be converted
 into its IP address.
 However, problems occur if the IP address of the target host changes.
 For this reason, you must adjust the RFC destinations if the IP address
 of the target host changes.
 If you specify the host name as a SAProuter name (/H/hs0311 instead of
 hs0311), it is not converted into its correspondidng IP address.
 Instead, it is stored in its SAProuter form in table RFCDES.

Load Balancing on File Adapter..

Hi Experts!!
We have run into an issue with load balancing on the sender side which can potentially cause one node to go down. We have 3 java server nodes on a single XI instance (ABAP & Java), when we pass about 30 to 50 messages of 10 MB size in a file-2-file scenario where each message is sent to eight different receivers, we have observed that the messages are picked up by only one server node on the sender side. The messages do get load balanced on the receiver side but I am not certain what controls this as we also observed that only one server node is active at a time on receiver side (round-robin). We use ABAP XSLT mapping programs with File content conversion on the receiver side.
We did find that by controlling the rfcengine threads you can load balance the distribution on the mapping service.
Can you please share your experience on how to control/configure load balancing of server nodes on both sender and receiver side in a single XI instance as well as in a cluster with 2 dialog processes.
Thanks in advance

Load Balancing in PI

Hi Experts,
Can any body explain how to do load balancing in PI7.0
What are the parameters needs to change related to Runtime WorkBench when doing load balancing.
Please provide if any one having material related to this.
Adavance Thanks
Rohit

Hi Rohit
The JAVA part of the XI has two main tasks at runtime: Carrying out the mapping and sending/receiving messages via the adapter framework (AFW). The first task (mapping) can be distributed over several J2EE server nodes, whereas the second (AFW) task can be distributed over several server nodes as well as with the help of a non-central adapter engine.Refer the installation guide for load balancing of PI 7,0

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

Hi MS DEF,
A second network adapter is required to provide peer-to-peer communication between cluster hosts. Please isolate your heartbeat network. With unicast when cluster is connected
to a switch, incoming packets are sent to all the ports on the switch, which can cause switch flooding, please confirm you have setup your switch correct, you can refer the following Cisco Switch related unicast configuration.

Load Balancing on XI

We need ideas to do load balancing for the IS by using external de-central adapter engine or use j2se adapter.
We are contemplating using a standalone Java instance and connect with the central adapter engine or use a J2se adapter to connect to central adapter engine. if we use a J2SE adapter we will not need a Java instance and therefore less resources on the box.
We primary aim is to use these adapters for load balacing purposes. We primarily use JMS adapters.
has anyone used de-central adapter engine and considered pros and cons vs J2SE adapter.
any comments are appreciated?
thanks

Hi,
Go to the runtime workbench --> Message Monitoring --> Click on the 'Configure Table Columns' > Check Sequence ID, Serialization Context & Sequential Number options.> and then click 'Apply'.
Then in the 'Serialization Context' column you will get the queue ID for the stcuk message.
Take that value and click on the 'Show additional Criteria' option on the top and put this value in the 'Serialization context' parameter. Also,select the start/end date as 'This year' --> start.
You will get all the messages stuck in that particular queue for this yoear, try to rectify them, so that your message will be processed.

Set up for TP Link Load Balancer model TL-R470T+

How to configure TL-R470T+ load balancer?
This topic first appeared in the Spiceworks Community

The default ip address for managment of this router is 192.168.1.253
HOWEVER this access point does not have DHCP turned on by default so you cant just connect (wired or wireless) and browse to that address!!!!
To get in intially you must assign yourself and address like 192.168.1.5, with a subnet mask of 255.255.255.0.
You dont have to put in the gateway but this will be 192.168.1.253.
So once you have done this you will be able to browse to 192.168.1.253 to setup the device.
unfortunatley these are usualy in chinese, which i dont speak so i cant help you there.
The default user and password is admin all lower case.
Once you into the device and have learnt chinese, you can then turn on dhcp and you will be assigned ip addresses automagically and can turn your adapter back to dhcp.
Good luck
