Configuring RFC connections for load balancing.

Hi ,
We have the following landscape for our systems.
The database is installed on z/os , db2 (mainframe). The central services( SCS and ASCS) are also on the mainframe. So the message server is on mainframe.
The CI is on AIX and The DI is on AIX.
We have Logon groups configured and load balancing Configured and is RFC enabled.
1) When we connect to SAP using the SAPGUI and the portal connection is made to either CI or DI depending upon the best response times. Now recently we are running the mercury load testing, all the users are connecting to DI. Why are the users connecting to DI even though we have load balancing?
2) I have a system with SID BP0, with one CI and one DI. The logon group is BP0 and the message server name is cyrix. Now I have other another system EP0. I have created a RFC connection from EP0 to BP0. In SM59 I have selected the load balancing option, and provide the message server name, SID and logon group name. The connection does not work. If I connect directly to the CI or DI the connection works. Please tell me how can I configure load balancing for RFC connections.
Thanks
Manmath.

Dear 917996,
There are two types of load balancing:
- Client-side load balancing (setting up the tnsnames.ora on client side). More information here (http://ggsig.blogspot.co.uk/2012/04/client-side-
load-balancing-in-oracle.html). Very good video produced my friend Igor Melnikov is here (http://www.dsvolk.ru/oracle/racdd4d/demos/video/loadbalance/client/clientloadbalance_viewlet_swf.html)
-Server-side load balancing (remote_listener and setting service parameter clb_goal). Very good Igor Melnikov's video is here (http://www.dsvolk.ru/oracle/racdd4d/demos/video/loadbalance/server/serverloadbalance_viewlet_swf.html).
I have read about client side and server side load balancing. By editing tnsnames.ora I have enabled client side load balancing which is suppose to select listeners at random. then why does it only go to second node?Could you please show your tnsnames.ora on client?
Please can anyone help me to configure server side load balancing with SCAN. I have read many many post but couldn't find a clear answer.Based on your output (remote_listener string cmbtrnrac-scan:1521) you have already configured the server side load balancing.
SQL> show parameter listener

Hello Reginald
Currently you have only basic network configuration, there is no loadbalancing config
I'm not sure what exactly you're asking about , but basically you need to have
- real servers configured on ACE (
http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA3_1_0/configuration/slb/guide/rsfarms.html#wp999495)
- serverfarm configured on ACE (

- L7 policy map (

And then apply it on necessary interface.
This is a general configuration, in your specific case you may need to configure some additinal features (e.g. I think you will need to have stickiness enabled
http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA3_1_0/configuration/slb/guide/sticky.html but it depends on your application)
links are for old config guids , but basic is pretty much the same for all versions.
Please check them and try to narrow down your question a bit.

Best practice for load balancing on SA540

Are there some 'best practice' guide to configure out load balancing on SA540 .?
I've got 2 ADSL lines and would like device to auto manage outgoing traffic .. Any idea ?
Regards

Hi,
SA500 today implements flow based round robin load balancing scheme.
In the case of two WAN link (over ADSL), by default, the traffic should be "roughly" equally distributed.
So in general, users should have no need to configure anything further for load balancing.
The SA500 also supports protocol binding (~PBR) over WAN links. This mechanism offers more control on how traffic can flow.
For example, if you have 1 ADSL with higher throughput than the other ADSL link offers, you can consider to bind bandwidth-hungry app on the WAN link connecting to the higher ADSL link and the less bandwidth-hungary app on the other one. The other traffic can continue to do round robin. This way you won't saturate the low bandwidth link and give users better application experiences.
Regards,
Richard

Need to configure output type for adobe form

Hello All,
I need to configure output type for Adobe Form thru NACE. What would be print program and how do I call my form from that program? and, what would be the FORM routine for that form in NACE?
I'm little confused, Pls I need your help.
Thanks in advance,
Chandra

Hi,
Just before few weeks we did this task.
Say for example if you want to print PO details through ADOBE form instead of normal sapscript layout or standard MEDRUCK, you can follow the following steps.
1. Design the form in SFP tcode, by passing the necessary inputs through form interface.
2. Then use tcode tcode NACE and select EF as application and click output types button on the application tool bar. Select NEU output type and double click processing routines on left side.
3. Then, in the right side of the screen we can see the calling program and the form (may be sapscript or smartform) whatever used.
4. For form names we have two options in NACE tcode.
One is Form and the otherone is PDF/Smartform Form. If you are using adobe form give your form name under PDF/Smartform and also select PDF under the type option in the same screen.
This worked perfectly for us. But pass the required parameters to the form from the routine used in standard program.
If any queries please post it.

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.

Configuring 2 NICs for Load sharing

I have 2 NICs installed in my desktop system. I need to establish a TCP/IP connection through one NIC With a server. At the same time I need to load balance the packets through both the NICs.
The above setup incolves coding in Windows. Also the implementation involves programming the dynamic routing table for packets to be distributed(for Load Balancing).
Also Wont there be any packet loss instances while drivin the packets through the NICs.
Any ideas and Suggestions on the above query is very much welcome.
Please elaborate the processes if possible.
Thank you.

Hi,
I'm guessing that your network cards will use some kind of channelling to load balance at layer2 and both cards will be treated as one logical link to the network. In Cisco speak this is called Etherchannelling however in other vendors speak it can be called trunking.
You will have to find out if this is true and then set up channelling using the correct method between your PC and switch. Unless you are using 3750 switches in a stack, i think both NICs will have to be connected to the same switch, both these ports will have to be put into the same etherchannel.
Cisco switches support the dynamic creation of channels using PAgp or LACP, my guess is that your NICs will either support LACP as PAgp is Cisco proprietary or it won't support the dynamic creation of a channel at all.
Have a look through the documentation and see if i'm on the right track, if so report back and if you need further help i can show you how to configure this on the Cisco switch.

CF8/JRun4 Cluster for Load Balancing

Does anyone have an example of how to set up a CF8/JRun4
cluster for load balancing?
I have three servers:
x004 - Linux - Apache2 (10.0.0.54,10.1.0.54)
x020 - Linux - JRun4/CF8 (10.0.0.70,10.1.0.70)
x021 - Linux - JRun4/CF8 (10.0.0.71,10.1.0.71)
Every server in our network has two network cards. One
network card is attached to 10.0.x.x which has a gateway to the
internet and runs at 100Mbps and is firewalled, and the other is
attached to 10.1.x.x which runs at 1Gbps and is internal with no
gateway. I'm trying to set it up so web traffic arrives on
10.0.0.54 into Apache and mod_jrun20 bootstraps a cluster named
STST using 10.1.0.54 which consists of STST_x020 coldfusion server
running on x020 and STST_x021 running on x021. I want the
communications between JRun4 on x020 and x021 to occur on the
10.1.x.x network and eventhough JRun and ColdFusion will only use
the 10.1.x.x network I still need the 10.0.x.x network card
attached for other purposes which require a gateway. I have
installed JRun4/CF8 about 10 times already and it seems I have no
control over what network JRun4 clusters on... sometimes it will
communicate on one, sometimes the other and without being able to
set which network is being used there always seems to be "network
error" on at least one of the two CF8 servers. I was able to get
everything working fine by disabling the network cards on the
10.0.x.x network and re-installing everything... but as soon as I
added the network cards back the whole thing was broken again.
How is this supposed to work? Most of the examples are either
no clustering or clustering on the same machine with Apache running
on the same box... I don't see any clustering across machines
examples.
How do I install a connector on a web server which doesn't
have JRun on it and get wsconfig to connect to a multi-machine
cluster when wsconfig only accepts a single IP address as a host
and the cluster is not listed?
How do I get JRun to bind to a specific network card?
Does this work if I choose a J2EE server other than JRun?
Any help anyone can provide is greatly appreciated. I'm
getting close to giving up which means staying on the non-clustered
environment and figuring out how we can deal with scalability by
switching to something else.

The article at
http://www.adobe.com/go/1e8e9170
is specific to configuring two or more cluster nodes that reside on
separate networks, e.g. 10.0.1.0/24 and 10.0.2.0/24. (The article
doesn't state it, but you can only use unicast peers if your
cluster nodes host a single instance of JRun or multiple instances
of JRun in the same cluster domain. When performing unicast
discovery, JRun looks for all Jini groups and not just the cluster
group.)
Anyhow, that's not your problem. The simplest solution is you
haven't enabled the jrun.servlet.jrpp.JRunProxyService service. I'm
most familiar with the Windows version of JRun, but I'm assuming
the directory structure is similar across platforms. In
<jrun_root>/servers/<name>/SERVER-INF/jrun.xml, set the
deactivated attribute of the jrun.servlet.jrpp.JRunProxyService
service to false and restart JRun. You should now see JRun
listening on the appropriate port. (The default for the first
manually created instance is 51000.) You can limit the proxy
service to a single interface using the interface attribute.
If you have enabled the proxy service, verify your security
settings in <jrun_root>/lib/security.properties. It's usually
best to limit access to specific hosts. Comment out the
jrun.subnet.restriction parameter and set the jrun.trusted.hosts to
the IP address of your web server, e.g. 10.1.0.54.
Forcing all JRun processes/services to listen on a single
interface isn't difficult, but it does require modifying quite a
few configuration files by hand. If you need assistance with that,
I can elaborate.
Configuring the JRun module under Apache is pretty
straightforward. If you're not using virtual hosts, it's very
simple. If you are using virtual hosts, it's still simple, but your
JRun configuration can be virtual host-specific.
On your Apache server, you'll want to create a directory
structure for the JRun module. I'll assume
/opt/jrun/lib/wsconfig/1, but you can use anything you want. Once
the directory structure is created, extract the appropriate JRun
module from wsconfig.jar to the new directory. You're most likely
interested in the Apache 2.0 module,
wsconfig.jar/connectors/apache/intel-linux/prebuilt/mod_jrun20.so.
Let's assume you've extracted the module to
/opt/jrun/lib/wsconfig/1/mod_jrun20.so. Your Apache service account
should have read, write, and execute permissions on the
/opt/jrun/lib/wsconfig/1 directory.
The JRun module configuration is normally appended to your
current httpd.conf file by wsconfig. Here's a sample configuration:
LoadModule jrun_module
"/opt/jrun/lib/wsconfig/1/mod_jrun20.so"
<IfModule mod_jrun20.c>
JRunConfig Verbose false
JRunConfig Apialloc false
JRunConfig Ssl false
JRunConfig Ignoresuffixmap false
JRunConfig Serverstore
"/opt/jrun/lib/wsconfig/1/jrunserver.store"
JRunConfig Bootstrap 10.1.0.70:51000
#JRunConfig Errorurl <optionally redirect to this URL on
errors>
#JRunConfig ProxyRetryInterval 600
#JRunConfig ConnectTimeout 30
#JRunConfig RecvTimeout 30
#JRunConfig SendTimeout 30
AddHandler jrun-handler .jsp .jws .cfm .cfml .cfc .cfr
.cfswf
</IfModule>
You may also want to update your DirectoryIndex directive
with an appropriate index page, e.g. index.cfm.
After the first request to a page handled by the JRun module
is received, the module will query the boostrap server,
10.1.0.70:51000, for a list of cluster peers. If you've configured
your cluster correctly, a line similar to following will be written
to /opt/jrun/lib/wsconfig/1/jrunserver.store:
proxyservers=10.1.0.70:51000;10.1.0.71:51000
You can create/edit this file manually as well.
Unfortunately, the bootstrap option only accepts one server. If
your bootstrap server is down, the JRun module will use the values
in jrunserver.store directly, if the file exists.
Here's a complete list of JRun module options:
metrics *
debugger *
ssl *
verbose
traceflags
serverstore
bootstrap
errorurl
apialloc
ignoresuffixmap
proxyretryinterval
connecttimeout
recvtimeout
sendtimeout
sslcalist
Options flagged with an asterisk can only be configured at
the Apache server level. All other options can be configured at the
server level and/or the virtual host level. The usage of these
options is in the JRun documentation, and the JRun module source
code is included in wsconfig.jar. Keep in mind that versions of the
JRun module shipped prior to ColdFusion 8 were coded to assign the
connecttimeout and sendtimeout options to the socket connection
timeout. Whichever option appeared last in your configuration ended
up as the final value. This has been fixed in ColdFusion 8 and
presumably the next release of the JRun updater.
I think that's a good start. If you need more information or
can't find what you need in the JRun or ColdFusion documentation,
let me know.
If you're looking for resiliency, I highly recommend
expanding your configuration to include a second web server and a
hardware load-balancer (preferably one that supports redudancy via
multiple paths and devices, e.g. devices from Cisco, F5, or Foundry
Networks). Often, however, running Apache on the ColdFusion
server(s) provides adequate performance, and round-robin DNS
records coupled with the ability to update DNS quickly in the event
of a failure may be all you need for load-balancing and
failover.

Round robin DNS for load balancing between multiple network adapters (Xserve)

I'm attempting to use 'round robin' DNS to load balance between the two ethernet adapters of an Xserve.
Both ethernet adapters are connected to the same LAN and have static IP addresses of 192.168.2.250 and 192.168.2.251.
The DNS zone for the server's local domain/host (macserver.private) has a machine record with both IP addresses (set up in the Lion Server UI).
Having read up on round robin DNS, I would have expected DNS requests for 'macserver.private' to be answered with the two IP addresses ordered at random, achiving my aim of requests being served at random via each ethernet adapter.
However this doesn't seem to be the case. Doing a 'nslookup' from any of the network clients results in the two IP addresses being listed in the same order everytime. And pinging 'macserver.private' only ever results in a response from the same address.
Does anyone know why this is the case? Does Lion Server use a non-standard DNS configuration? Are there any additional settings I need to configure in Lion's DNS server to make adopt a round robin approach to responding to requests?
Thanks in advance for any help!

Be careful what you wish for
Round Robin DNS is rarely the best option for 'load balancing'. At the very least it's subject to caching at various point on the network - even at the client side, once the client looks up the address it will cache that response - this means that subsequent lookups may be served from the client's cache and not refer back to the server. Therfore any given client will always see the same address until the cache expires.
I suspect this is what you're seeing.
You can minimize this by setting a lower TTL on the records. This should result in the response being cached for a shorter period, meaning the client will make more requests to the server, with a higher change of using the 'other' address.
However, you're also going to run into issues with the server having two interfaces/addresses in the same LAN. This isn't recommended.
As Jonathon mentioned, you may be better off just bonding the two interfaces. This will provide an automatic level of dynamic load balancing without the latency of DNS caches, as well as automatic failover should one link fail (as opposed to round robin DNS which will cause 50% of requests to fail until the client cache expires and a new lookup is performed (and, even then, there's still a chance the client will try to use the failed link).

WebAS access via Portal: Web Dispatcher required for load balancing ABAP

Hi Folks -
We have EP 6.0 SP18 (Java only, WebAS 6.40, Unix/Solaris). The portal has a CI/SCS and one DI so we have a Web Dispatcher to load balance the portal servers. This works fine (and provides port 80 access).
This portal will provide access to HTTP services from an ABAP WebAS (6.20 with 6.40 kernel, Unix/Solaris). A landscape configuration entry has been added to the portal for this ABAP system. The ABAP system has a CI and multiple app servers, all capable of handling HTTP requests. This will also require port 80 access.
1. Will we need an additional Web Dispatcher to load balance HTTP requests to the 'backend' ABAP WebAS system, or will the portal be smart enough to handle the load balancing itself (perhaps based on the information in the landscape configuration)?
2. If the portal itself handles the HTTP load balancing can you point me to documentation (so I can make sure I have proper configuration)?
3. Are there any changes to this with NW2004s Portal (we plan to upgrade soon)?
Thanks in advance! Jeff

Jeff,
Regarding:
Q1. If you create a system object from the "SAP system with load balancing" template in portal and configure the object to point to your CI (msg server), the LB should be handled.
Q2. Portal load balancing is handled by the message server. If you point a test URL to the port of your message server, you will notice that you are issued a redirect the URL of your dialog instance. The web dispatcher is just a proxy (with some intelligence). When a request is made to the WD, it makes a connection to the MSG server, the list of active instances is queried, a redirect is made to that instanct. If you use WD, that connection can be proxied behind a standard URL. If you connect directly to the MSG Server instead, you will notice your URL change, just as it does on the service marketplace.
WDs are good for providing services, masked (proxied) behind virtual names. If you do not want the customer to see a physical URL of the server, use the WD. There are lots of other solutions that can do this too though such as Apache, ISA, Juniper devices, Cisco LDs. WDs have a very low performance threshold though, especially if you use SSL. WD is a performance bottleneck and should be benchmarked to see if it is right for your application.
Q3. No changes this architecture in 04s.

Are you running Apache/Jserv on a server with any other applications, or is Apache by itself?
If you are not using JVM, how many httpd processes do you get before Apache implodes? We stopped in the water at 90 httpd processes, but performance degraded starting at 70 sessions.

Using Web Cache to load balance servlet-based Forms (6i and 9i) is unofficially supported. I say "unofficially" because we have actual customers doing it and getting support, but the 2 development teams (Forms and Web Cache) haven't actually done any integration testing of this sort of configuration yet. For your case, please contact your Support rep and ask what was done to use Web Cache as a load balancer for Forms6i at METRO in Germany. The Forms product managemment team is writing up a white paper to describe how to do it, but until then, you'll need to go through Support. Please contact me if you want more information.

Mod_oc4j for load-balancing

Guys,
Looking for some feedback on DMSMetricCollector when using "metric" as the selectmethod for load-balancing. What i want to know is that whether the DMSMetricCollector can be configured to use multiple metrics such jvm-heapsiize, servlet-processRequestTime etc, Connection-pools FreePoolSize.value etc ? the documentation doesn't explicitly mention that if its possible, apparently it doesn't but want to check from the experts here, Steve you might have something on this...
Or if there is any other implementation available which supports load-balancing based on multiple performance metrics
Thanks and Regards

can i use this loadbalancer.jar or not?

New CAS for Load Balancing Exchange 2007

I want to add a new CAS to an existing Exchange 2007 environment (there is already one CAS and it functions properly) to allow for load balancing. After adding the new server I wanted to do some testing (before I actually set it up for load balancing).
If I try to log in to a mailbox using OWA I get an error stating that "Exception type: Microsoft.Exchange.Data.Storage.ConnectionFailedTransient ExceptionException message: Cannot open mailbox". I am sure I am missing something simple, but cannot
figure it out. Could someone point me in the right direction?

Is your new CAS in the same Windows site as the rest of your Exchange servers? In Exchange 2007 and 2010, the CAS needs to be in the same Windows site as the mailbox it is servicing (unless you are accessing from the Internet and the other site has
no externally accessible CAS).
