Load balancing between application server and database

Hi,
is there any load balancing between the application server and the database? Consider we have a single instance of an application server that sends database queries from different clients to the database. Are the requests queued in some way at the application server, allowing to control the flow of the queries (e.g. queries from "more important" clients might be sent with a higher priority)?
Thanks for your help!

Hi Victor/Jim/Volker,
Thanks a lot for all the responses..
Just wanted to let you guys know that my installation finished successfully.
The thing which confused me was that my Qtime, Qdate and everything else was showing correct values..
Well, my problem I set the environmental variable PASE_TZ to the EST time zone on a SYS level using WRKENVVAR>F4>SYS and added the variable. I logged off and the sidofr logged off, but one user which should have logged off and didn't was the "SAPINST"(my installation user) which was logged in the subsystem TMKSVR00.
Even when I had closed the SAPINST installlation program, the user doesn't log off...it just sits there until and unless u shut him out of the system using the option 4 on wrkactjob for ending the JOB(SAPINST logged in the system below the TMKSVR00 subsystem)
So since the SAPISNT user never logged of, his environmental variables were not initilized properly, even after the changes...
This thought came to me almost after a 6 hours of wasting my time searching for notes here and there...
I think when u end/stop the install in SAPINST, the SAPINST user should log off the AS400 system, but I have noticed, it never does...although when u restart the installation, if u have noticed it shows you the log on for the SAPINST user in the TMKSVR screen...
Its kind of buggy, I would say...
I have noticed, that even when I log on to AS400 from home or from a remote PC using Emulator, it shows me logged in the subsystem and even after i have logged of, it still shows me there...
Anyway, thanks a lot guys...for all your responses..
Just wanted to let you know all.
Thanks
Abhi

ARCHITECTURE OF SAP R/3 AND APPLICATION SERVER AND DATABASE SERVER IN ABAP

ARCHITECTURE OF SAP R/3 AND APPLICATION SERVER AND DATABASE SERVER IN ABAP?
PLEASE EXPLAIN

hi
Presentation Server
It is actually a program named sapgui.exe.
It usually installed in users workstation.
The interface accepts the input from the user in the form of keystrokes, mouse-clicks, and function keys, and sends these requests to the application server.
It receives and displays the result from the application server.
Application Server
An application server is a set of executables that collectively interpret the the ABAP/4 programs.
Each application server has a profile called application server profile, that specifies its characteristics when it starts up and while it is running. It specifies:
1. Number of processes and its types.
2.Amount of memory each process may use.
3. Length of time a user is inactive before being automatically logged off.
If your ABAP/4 program requests information from the database, the application server will format the request and send it to the database server
Database Server
The database server is a set of executables that accepts database requests from the application server.
These requests are passed on to the RDBMS (Relation Database Management System).
The RDBMS sends the data back to the application server.
The RDBMS may run on database servers computer or may be installed on its own computer.
The components of application server are dispatcher, dispatcher queue, work process.
All requests that come in from presentation servers are directed first to the dispatcher.
The dispatcher writes them to the dispatcher queue.
The dispatcher pulls the requests from the queue on a first-in, first-out basis.
Each request is then allocated to the first available work process.
A work process handles one request at a time.
The work process needs two memory areas, the user context and the roll area.
The user context is a memory area that contains the information about the user.
The roll area is a memory area that contains about the program execution.
User Context
User context is a memory area that contains the characteristics of a user that is logged on the R/3 system.
1)It holds, users current settings.
2. The users authorizations.
3. The names of the programs the user is currently running.
When a user logs on, the user context is allocated for that logon. When logs off, it is freed.
Roll Area 
A roll area is a memory that is allocated by a work process for an instance of a program.
It holds the information needed by R/3 about the program execution, such as: 1. The values of the variables
2. The dynamic memory allocations
3. The current program pointer.
Each time a user starts a program, a roll area is created for that instance of the program.
If two users are using the same program at the same time, two roll areas will exist-one for each user.
The roll area is freed when the program ends.
Both roll area and the user context play an important roll in dialog processing
pls reward points dor useful ans

Difference between application server and central instance

Hi everyone,
whats the difference between application server and central instance and message server. where it will be installed. and how?
Regards
Basis Fresher

Hi,
just want to clarify that is is not correct that only one enqueue process can be configured on the CI.
Please see the documentation within transaction RZ11 for the parameter Parameter : rdisp/wp_no_enq
Short description : number of enqueue work processes
Parameter description :
You can use this parameter to define the number of enqueue work processes for the instance.
Ensure that a value >0 is only set on the central instance that provides the enqueue server (instance rdisp/enqname ). One enqueue work process on the central instance is normally sufficient (rdisp/wp_no_enq = 1); only in very large systems can a higher value be useful.
Kind Regards

RE:difference between application server and web application server

hi,
i am a fresher to SAP.please tell me the difference between application server and web application server so that my doubt will be clarified.

Hi,
the SAP Web Application Server is the reliable, open standard-based application server from SAP. It supports both J2EE and ABAP, and serves as the underlying infrastructure for all new and upcoming SAP solutions, like SAP R/3 Enterprise, SAP Portal, SAP Exchange Infrastructure, and all other SAP components.
The SAP Web Application Server is not a new product, it is the natural evolution of proven SAP application server technology formerly known as SAP Basis. It provides the platform to develop, execute, and operate Web applications and Web services as well as traditional SAP GUI based applications
if it helpful rewards points are appreciated

Interface: it is a program that performs communication with External system from SAP.
There are two types of interfaces:
1. Inbound Interface: External system sends the data to SAP
2. Outbound Interface: SAP sends the data to External system.
Let's take a scenario:
There are two Systems SAP ERP and Seibel CRM
Scenario1: Whenever an Order is created in Seibel CRM system it has to be transferred to SAP where the Order confirmation, Delivery and Billing will be performed. This can be enabled by using IDOC as inbound interface.
Scenario2: Whenever a New customer is Created in SAP ERP this customer data has to be transferred to Seibel CRM using Outbound IDOC / RFC.
Basically interfaces are implemented using RFC, BAPI, ALE/IDOC.

How to properly load balance between diffrent server farms.

Hi experts,
We are using an ACE 4710. We chose for our server farms to load balance using the least_connections predictor. it seems to work fine inside the same server farm but is it working properly between server farms? It doesn't seem because some of my real servers seems to be more loaded than others. Each server farm are using the same real servers.
Any idea about what is the problem or any suggestion regarding the best load balancing predictor we should use using this kind of configuration?
Thank's to all.

The ACE uses load-balancing algorithms or predictors to determine how to balance the traffic among the devices configured in the server farms, independent of the device type. For FWLB, we recommend that you use only the hash address source and the hash address destination predictors. Using any other predictor with FWLB may fail and block traffic, especially for applications that have separate control and data channels.
Here is the configuration guide for the Cisco ACE 4700 Series Appliance Server Load-Balancing.

Communication between Appliation Server and Database Server

If a web app is deployed to an Oracle Application Server, this AS machine is physically connected to an Oracle Database (server) machine in the same location:
For the purpose of sending and retrieving data from AS server to/from DB server, do I need to install any communication/network software on the both (AS and DB) machines? If so, what kind is needed?
Otherwise, I would assume two network cards plus a cable/wire will do (but not sure).
Thanks
Scott

If you are using the Oracle Type 4 (thin) JDBC driver, you shouldn't need to configure the tnsnames.ora or sqlnet.ora files.
Neither the OCI nor the thin driver will use ODBC, which is generally only available on Windows. Sun puts out a JDBC-ODBC bridge driver, but I don't know of anyone that has intentionally used that particular driver in production code in years. Whether the thin driver is faster than the OCI driver depends heavily on the driver version and the particulars of your application's workload. It's generally best to benchmark both with your code if you are concerned with driver performance.

Load-Balancing between Foreign and two Anchors

Hi, we have two foreign controllers (one active, one standby) and two anchor controllers. All APs are connected to the active foreign controller. The layer 3 networks for the wlan clients on both anchors are different for the same SSID. SSID: Internet, anchor 1: Subnet A, anchor 2: Subnet B. So when a client is getting anchored to Anchor 1, the clients will get an ip from subnet A and when the client is getting anchored to anchor 2, the client will get an ip from subnet B.
This is so far not a big problem because we only have a few accesspoints in some rooms. But what will happen, when we have a full covered wlan and the client roams from one AP to the other AP? Is there a possibility, that the client will anchored to a different anchor while roaming? I think this will result in a lack of connectivity because without a real disconnect the client will not ask for a new IP address.
Other question: Is it possible to disable this load-balancing between anchor controllers? Or can i make a client sticky to only one anchor as long as an access-session is established?
All controllers are 5760 with 3.3.3 software.

Hi acontes,
It's an interesting question.
In this case, if all AP's are on WLC-A and there is no possibility that an L3 inter-subnet roam will occur between WLC-A and WLC-B, I would just forward WLC-A to Anchor A and WLC-B (in the event of fail over) to Anchor B (if Anchors reside on different subnets). If you must specify Anchor A and Anchor B on each WLC for redundancy purposes, it's important to understand the guidelines and limitations with regard to Foreign / Anchor Design.
As Scott mentioned, the limitation with Anchoring design is that there is no primary / secondary configuration for an Anchor on the Foreign WLC.
If WLC-A has two entries (1) for Anchor-A and (2) for Anchor-B, the EoIP tunnels are establish and load-balancing occurs in a round robin fashion.
Keep in mind the following with regard to guest N+1 redundancy:
•A given foreign controller load balances wireless client connections across the list of anchor controllers configured for the guest WLAN. There is currently no method to designate one anchor as primary with one or more secondary anchors.
•Wireless clients that are associated with an anchor WLC that becomes unreachable are re-associated with another anchor defined for the WLAN. When this happens, assuming web authentication is being used, the client is redirected to the web portal authentication page and required to re-submit their credentials.
Since traffic is transported at Layer 2 via EoIP, the first point at which DHCP services can be implemented is either locally on the anchor controller or the controller can relay client DHCP requests to an external server. Since the IP address directly correlates to the DMZ subnet or the interface where the traffic egresses, it is possible for some clients to get IP's from both Subnet A or Subnet B in the event that WLC-A is building EoIP to both anchors.
1) What happens if my clients roam?
Nothing... since all AP's are on WLC-A, it's Intra-Controller Roaming
Each controller supports same-controller client roaming across access points managed by the same controller. This roaming is transparent to the client as the session is sustained, and the client continues using the same DHCP-assigned or client-assigned IP address. The controller provides DHCP functionality with a relay function. Same-controller roaming is supported in single-controller deployments and in multiple-controller deployments.
Would it be better to choose the same DHCP Pool on both anchors?
It's probably better to have redundant anchors on the same subnet, but it's not required.
3) How would you design this :-)
WLC-A <--EoIP--> Anchor A (DHCP Pool A)
WLC-A <--EoIP--> Anchor B (DHCP Pool A)
It's important to remeber what Scott mentioned about the lack of a primary / secondary relationship. If multiple controllers are added as mobility anchors for a particular WLAN on a foreign controller, the foreign controller internally sorts the controller by their IP address. The controller with the lowest IP address is the first anchor. For example, a typical ordered list would be 172.16.7.25, and 172.16.7.28. If the first client associates to the foreign controller's anchored WLAN, the client database entry is sent to the first anchor controller in the list, the second client is sent to the second controller in the list, and so on, until the end of the anchor list is reached. The process is repeated starting with the first anchor controller.
If any of the anchor controller is detected to be down, all the clients anchored to the controller are deauthenticated, and the clients then go through the authentication/anchoring process again in a round-robin manner with the remaining controller in the anchor list. This functionality is also extended to regular mobility clients through mobility failover. This feature enables mobility group members to detect failed members and reroute clients.

Load balancing on RMI Server Application

Hi there, I'd like to know more detail about load balancing on RMI server application, been digging the web for some time, but couldn't find much information, does anyone know any website or has the knowledge of load balancing on RMI to share? Sort like its design and implementation.
Thanks,
Jax

I want performance and fault-tolerance,
In that case, is it necessary to have a main
rmi server to allow client to access and pick one of
the rmi servers for the client?Well, if you have one main RMI server, you have a single point of failure again.. Why can't your application know about all rmi servers, and randomly choose one? If it's down, pick a different one.. If your applicatoin is an applet, you'll have to sign it.. Do that and put it on 2 redundant web servers. You have performance by splitting the load and you have your fault tolerance by having x identical rmi servers.
If you're saying what I think, why would you have one main rmi server that picks a different rmi server? That's more work AND your redundancy goes byebye, ie if your main rmi server dies..

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.
