Srv2008 r2, Load balancing causing sessions to Stack and halt logon

Hello all,
We have currently using Appv 4.6 sp3, across 14 terminal servers. These then have access to 2 app servers and also 2 bkr servers.
We are running a srv2008 r2 environment, and running a windows 7 user experience on the terminal servers.
We are running microsoft load balancing via a farm setup. The member of staff that set they system up has recently left and with limited documentation I am struggling a bit to get my head around why the stacking occurs
The problem we have come across is that the system work ok load balancing works a treat, then all of a sudden a user will come along try log on and will take longer than usual to connect there session. This is causing all users that try connecting
to be stacked behind this slower user logging on and so to a point where there could be 20 + people waiting to log on.
This causes us a huge problem as we can have almost 700+ use at a time on the thin client environment.
Is there a setting that can be set to stop this situation happening, ??
Thanks in advance
Lee

Hi Lee,
Does this issue occurs with all users at a time?
Do you have printer redirection enabled?
If yes, then please try below Hotfix and check the result.
Long logon time when you establish an RD session to a Windows Server 2008 R2-based RD Session Host server if Printer Redirection is enabled

Hardware load balancing with session stickiness

Hello,
          We are looking for a hardware based solution to load balance 4
          unclustered weblogic servers. These servers are software replicas of
          each other and share a common database. We need a solution that
          provides session level server stickiness based on jsessionid as both a
          cookie and url rewrite. Currently we have Cisco load balancers which
          do not handle the url rewrite due to the fact the the load balancer
          only "sees" what is after the question mark in the url and the
          jsessionid is before the question mark. Example:
          http://somehost.com/some/url.jsp;jsessionid=26D5C566075663ABD8E17AD255974323?parm=value
          I'm sure we are not the only ones trying to do this. Any suggestions
          would be greatly appreciated.
          Thanks,
          Alan George


          Having worked on Cisco load balancer and WLS clustered, you would loose sessions
          when the requests are failed over.

CISCO Load Balancer with SAP on Unix and Oracle

Hello Experts,
Explain me the steps How CISCO Load balancing Mechanism works with SAP Enterprise Portal?
If anyone implemented and achieved the same,please explain me the steps to follow from Initial Stage to end of implementation.
Or If you have any documentation on this just share with me or point me to the particular link.
I have seen the below SAP help which is somewhat helpful.
http://help.sap.com/saphelp_nw04s/helpdata/en/d3/e12840d89d185de10000000a1550b0/frameset.htm
I would like to know how CISCO will connect to M/essage Server /Java Dispatcher.
And explain me the steps to follow to implement External Facing Portal using Cisco Loadbalancer.
This should be achieved in Unix environment.
Any help would be greatly appreciated.
Regards,
Karthick Eswaran
*Points will be rewarded for helpful suggestions

We use F5 for loadbalancing, but all hardware loadbalancing solutions should similar. They offer multiple algorithms, we use simple round robin (SAP's webdispatcher has better options for load balancing). You create virtual IP to your CISCO loadbalancer. You then configure Cisco to route traffic to each portal application server. If you have CI + 2 appservers, you configure the loadbalancer to send traffic to cihost:port, appserver1:port, appserver2:port. You also create a DNS alias to the virtual IP of the loadbalancer. End users will use the DNS alias to connect your portal. Typically you use standard ports (80 & 443) on Cisco, so that end user URL does not contain any ports (so http traffic goes to port 80, https goes to port 443). You also need to enable cookie persistence on the load balancer for session persistence.
For external facing portal, you need to have your loadbalancer in DMZ and you want to use SSL. You also need to setup firewall rules for your portal and backend servers.

Lync 2013 Enterprise load balancing on the front end and edge pool

Hi,
I am setting up a Lync 2013 Enterprise deployment consisting of a Front End pool (x2 FE servers) and an Edge pool (x2 Edge servers). I'm seeing some conflicting advice regarding load balancing using hardware or DNS for the front end and the edge.
On the front end I have 2 internal DNS records 'lyncfepool1.contoso.local' each of which map to one of the IPs of the FE servers. I've used my details to populate the Detailed Design Planner excel spreadsheet and am told that I require a HLB to load
balance my front end pool. I'm aware of the need to load balance HTTPS traffic internally (which will be done by TMG) however other traffic to the front end (SIP, etc) can be balanced by DNS only, and not require a HLB?
Can someone clarify the front end requirement?
Also - looking now at the edge pool - this site again have two edge servers in a pool. We are using a total of six private IP addresses, two per edge service (2 x av.contoso.com, 2 x sip.contoso.com and 2 x webcon.contoso.com). These will be
NAT'ed by the external firewall and directed to the respective external (DMZ) IP addresses on the Edge servers on port 443. I know this isn't true roundrobin due to the intelligence of the Lync client when connecting (in that the Lync client will connect
to one of the public IPs and if it can't connect, it will know to connect to the other service IP), however I want to clarify this set up, particularly the need to direct the external public IP traffic at the DMZ Edge IP specified in the topology builder.
I've attached a basic diagram of the external/DMZ/Edge side which hopefully helps with this question
Persevere, Persevere, Per..

That is because you will always need HLB for a front-end server since it hosts the Lync webservices which use HTTP/HTTPS traffic.
The description on the calculation tool also describes this correctly:
Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing or a combination of DNS load balancing and device-based load balancing (for
Lync web services)
You can use either Hardware or DNS loadbalancing for SIP traffic only, but you will always need a HLB for the webservices. Both are applicable for the Front-End so you have either
full HLB for both SIP and HTTP(S) traffic
DNS LB for SIP traffic and HLB for HTTP(S) traffic
Hope this is more clear :-)

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application

Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance

I have read the doco by Ivan Kovacevic amongst many others but as my clients and servers are on the same subnet, the config doesnt work.
Can anybody point me in the right direction please. The devices are ACE 4710 running A3(2.3).
Thanks

Try using the following configuration:
Note: Please make sure to configure also a udp probe to probe udp port 69, in case the application is down.
You need to configure a management policy on the interface when using a UDP probe.
That is because, when port 69 on the server will be unreachable, the server will send an ICMP unreachable.
ACE will consider a udp probe as "failed" only when it sees ICMP unreachable.
Without a management policy-map, the ICMP unreachable message will be dropped.
Also, add an ICMP probe to the rserver because udp probe will not be enough when the physical interface will be down.
That is because UDP is a connection-less protocol. To consider a UDP probe successfull, ACE need to see NO answer from the server in respose to the probe.
The ACE will not see any answer from the server when the interface is down and thus, will consider the probe as "sucessful".
With ICMP probe attached to the rserver, you also test the reachability of the server and not only the UDP port.
Here is the configuration (of course, you can chage the names of the of the objects to the name you are using if you want) :
access-list ALL line 10 extended permit ip any any

Monitoring Load balancing in Tuxedo 9.1 and RAC ?

Hi all,
I wrote this question in the old forum bea [http://forums.bea.com/thread.jspa?threadID=300006084], and now I have more question about monitoring of load balancing in tuxedo with RAC:
How can I monitor the load balancing in Tuxedo with RAC?
How can I check that the load balancing of tuxedo is running correctly?
How can I know that group are using my requests?
We need know if the request use the instance ORARAC1 (groups GRP_A1 and GRP_A2) or
use the instace ORARAC2 (groups GRP_B1 and GRP_B2).
There is some tool (similar txrpt) that displays this information in tuxedo 9.1?
Thanks in advance
P.D.: Excuse my english

Logistics Management vs Supply Chain Management
Chapter 1 Logistics
1.1 Logistics Management vs Supply Chain Management
First of all, we must clarify this big semantic matter: what is logistics? what is Supply Chain ? are these two names equivalent?
We can represent this question by this figure
Is SC part of the logistics? or is it the reverse? or is logistics replaced by SC? or are both the same? or are logistics and SC covering partly the same matter but both continue to exist ?
To answer to that question, we have to consider the definition of each concept. We use the definitions commonly accepted by the CSCMP (Council of Supply Chain Management Professionals). These definitions also are used by the APICS (The Association for Operations Management: the global leader and premier source of the body of knowledge in operations management, including production, inventory, supply chain, materials management, purchasing, and logistics.)
The logistics management is that part of the Supply Chain process, which plans, implements and controls the efficient, effective flow and storage of goods, services and related information from the point of origin to the point of consumption in order to meet customers’ requirements.
The supply chain management is the integration of key business processes, from the end user through original suppliers that provides products, services and information that add value for customers and other stakeholders.
Thus the answer to our first question is clearly
In a Supply Chain, each enterprise is a partner; each partner is fully responsible for a process that transforms inputs into outputs using some resources and following the rules or norms.
The concept of supply chain suggests a series of processes linked together (they form a chain !).
Figure 3
Somebody is the producer of the raw material, somebody transforms it into a product, somebody incorporates the product into an assembly, somebody stores the finish good, somebody sells it, somebody transports it and finally a retailer sells it to a final customer who is the consumer.
Some of these processes are sourcing, others are manufacturing and others are distribution.
If we illustrate the system for a more complex product, we obtain the hereunder schematic.
The pilot of the Supply Chain must instruct each supplier about when and to whom they have to deliver their products. He must instruct supplier "A" to first supply "B" and later the main manufacturer; for another part, he must instruct "B" to first supply the main manufacturer and later the supplier "C", if it is the right way to get the product on time as promised to the customer.
Figure 4
1.2 Flows
As indicated here above, all the partners are linked (they form a chain). These links cover 3 flows:
1. physical product flow (material flow)
The materials flow from suppliers to customers and from customers to suppliers (reverse flow).
The products are packaged (primary package, secondary package, warehousing package, transport package). Each package fills a specific function. (to see chapter 6). Containers, pallets and some packaging are circulating round trip.
The management of the materials flow must deliver products on time, in the proper sequence, exactly where they are needed.
2. information flow
Information is flowing in both directions, is passing each other, is colliding with others …
The information include order, delivery, inventory level, production status, forecasts, quotation …
The information could be considered as the piloting system of the other flows.
The information is flowing between multiple organizations and enterprises, each one having its own managing system, its own value system ….
3. financial flow
They include credit terms, payment schedules, title ownership arrangements …
A major problem concerns the coordination, the synchronization between all these flows. The final objective of the logistics / supply chain is to reduce costs and to improve service levels at the profit of all the partners of the chain, suppliers, manufacturer and customer. Each activity playing a role in making the product and the services conform to customer requirements (cost, delivery terms, quality …) is concerned.
In the past, each enterprise was trying to strangle other enterprises to obtain the major advantage (and to avoid realizing some effort). The bigger was crashing the smaller.
Today, no single enterprise is solely responsible for the competitiveness of its products and services. The benefit obtained by working in network must be shared between all the members of the chain. The sole strategy that performs is the win-win strategy.
The competitiveness suppose to give a better service, a superior service to the final user of the product / service (decreased delivery times, repairing/exchanging defective parts, maintenance, warranties, price, reliability, performance).
Today, we have to consider the total system wide cost; it includes manufacturing, transportation, packaging, warehousing, distribution, rework, repair, administrative costs. Managing the supply chain is not minimizing a single cost between two entities but, rather, on taking a global system approach to get, at the end, the better result that profits to every chain partner.
If one looks at actions in isolation, it is not possible to have a global view and to identify how an isolated action could have a reverse effect. Each decision taken by a partner of the chain has an effect on the upstream and downstream partners. And this effect could be positive or negative. For example, a supplier will reduce its inventory that leads to increase the delivery terms of the downstream partners; for example, a transportation manager will delay a delivery to increase the volume to transport and to reduce the transportation cost.
1.3 Management
It is obvious that designing and operating a supply chain so that total system wide costs are minimized and system wide service levels are improved is very challenging. It is not easy to do that inside a single enterprise, how more if one must consider several enterprises. We could write that the complexity increase exponentially with the number of partners.
with C = complexity of management, k a function depending of the product and n = number of partners.
The criteria to be considered are:
q the complexity of the network mainly if the partners are located over a large geographical area
q the cultural clash between partners
q the difference of capacities of partners: some are SME, others large enterprises, some are assembler, others are machining and some are giving service … Each partner has its own limits, its own capacities and its own resources. It is not thinkable to build a supply chain only with partners having the same constraints.
q the planning process could be different depending of many factors external to the supply chain. It is normal that an enterprise could be partner of several supply chains (example: the ball bearings supplier belongs to several automotive manufacturers supply chains).
q the supply chain is a dynamic system that evolves over time. Everything can change quickly or frequently either on the customers’ side, either on the suppliers’ side, either the market conditions, either the environmental conditions.
1.4 Three levels of management
As every activity, we have to consider the three levels: strategic, tactical and operational.
a) Strategic level.
The strategic level deals with decisions that have a long-lasting effect on the enterprise.
Every department or service has to fit with the strategy of the enterprise.
q The Supply Chain strategy must deal with the procurement of raw materials and all the components used by the enterprise.
Procurement includes packaging, transportation, documentation, warehousing.
q The Supply Chain strategy must deal with the logistics operations inside the manufacturing plant
This includes the flows through the plant, the interoperations packaging, the information, the traceability …
q The Supply Chain strategy must deal with the distribution and usage of the product by the customer.
This includes the selection of the distribution channels and the operations to supply the retailers, the instructions of use and all the operations covered by the warranty and the after sales service.
The long-lasting effect must be considered by product. If the life cycle of the product lasts several years, the strategic level covers more than 2 years; if the life cycle of the product lasts less than one year (i.e. tamagushi ….), the strategic level is not a fundamental step. But reasonably, the strategic level for the majority of the products covers 2 or 3 years.
Some of the basic questions are: 1) make or buy question;
2) location and capacities of production facilities, warehousing, transportation;
3) technologies to be mastered;
4) machines and equipments to be used, rented or …;
5) layout of the production facilities and warehouses;
6) quantities of products to be purchased, launched in production, stored, packed together, transported;
7) the relevant information for the manufacturing;
8) the training of the operators;
It is obvious that all this has a cost and therefore has to be amortized on several years.
b) Tactical level.
The tactical level concerns generally a period of time of one year. It is prepared during the last quarter of the previous year.
The tactical level has to focus on the expected situation at the end of the previous year to establish a series of significant data as 1) quantities to be distributed on each market;
2) exact quantities of raw materials and components to be purchased and when to place orders 3) the planning of manufacturing by quantities, by specifications, …
4) the distribution activities by month, mainly if the products demand is seasonal;
5) to prepare the impact of the promotions on the distribution;
6) to optimize all the logistics functions;
7) to fix the key indicators to allow a performing management;
8) to establish the calendar of each specific step to reach the annual objective;
9) to match demand and supply
The tactical level is the annual budget.
c) Operational level.
The operational level is the real time management. Some activities are planed on one week, others on a day and the updates are permanent. The operational level has to face the failure of a truck, the illness of a warehouseman or a driver, a urgent non planed order, and so on.
The quality of an organization can be measured by the respect of a well constructed plan and by the reactivity face at unforeseen situations. No waste of time, no waste of resource must be the rule for the operational manager.
He must be able: 1) to meet the better lead-times,
2) to respond to any fluctuation of the demand,
3) to deal with all the products (from fast moving goods to industrial component),
4) to face any unexpected situation.
To do that, he must pilot several logistical drivers as forecasting, transportation means, warehousing facilities, inventory, orders management, sourcing possibilities … and these drivers are fed by information. All these drivers can add value or cost at the customer’s eyes.
q Forecasting allows to feed all the other drivers
q Adapted transportation means allow fast loading and unloading and reduced operational costs by comparison with the value of the transported goods
q Warehousing facilities are located at the best operational place to supply their customers (outbound) and to receive goods from suppliers (inbound); they have well adapted infrastructures to store goods. The objective is to get the better responsiveness, to get the better control on each local market, to get the cheapest cost.
q Inventory must be adapted to the demand: enough to face unexpected demand and not too many what carries overstock and therefore additional costs and ageing products.
q Orders management reduces lead time and allows a full control on all the documents issued from these orders as picking ticket, packing list, invoice, …
q Sourcing possibilities allows a better control on the products arrival, access to the docks without waiting times, better management of the purchase orders …
We can summarize all these concepts by 3 curves as follow and the total logistics cost is the sum of these three costs:
Figure 5
We can represent these situations by the following outline representing three concrete situations:
Figure 6 a Figure 6b Figure 6c
Figure 6a represents 4 suppliers delivering to 1 central warehouse and from this warehouse to the customers;
Figure 6b represents 4 suppliers delivering to 2 central warehouses and each warehouse delivers to its customers;
Figure 6c represents 4 suppliers delivering to several warehouses and each one delivers to its own customers.
It is necessary to determine the number of warehouses, their locations, their sizes, the quantity of products to be stored and the location and number of customers to be supplied to get the best service at the lowest cost. The enterprise must compare the costs of opening more warehouses and the benefits to be closer to the customers.
For another part, it is important to take into account the specificity of the warehouses: only to supply a manufacturing facility, only to supply end customers or supplying both manufacturing facility and end customers. The basic functions are the same but they are several important differences:
q to supply a manufacturing facility means many suppliers (for raw materials and purchased components) and a few customers (manufacturing sections).
q to supply end customers means very few suppliers ( final assembly line) and a large number of customers (all the customers for finished products and spare parts)
q other differences concern the quantities, the size, the physical configurations, the variability and predictability of the demand, the unforeseen breakdowns (machines, trucks and trailers …), the capacity of each buffer between each manufacturing or supply process, lead-times acceptable by each downstream customer, size of batches, safety inventory size, risk parameters …
1.5 Supply Chain Information
As here above mentioned, information feeds all the logistics drivers. Therefore, it is important to detail the content of these information. The supply Chain Management manipulates a lot of information that each one affects strongly or weakly the results. Firstly, we have to consider the information that affect directly all the logistics drivers.
Forecast is affected by the economic situation of the market, by the financial situation, by the wealth of the population, by the obstacles to the trade, by the adequacy between the specifications of the product and the needs of the customers … All the data concerning these parameters must be considered as useful information.
Inventory is needed to face the responsiveness to the demand of the market. The Supply Chain Manager must know this requirement to establish correctly the level of inventory for each item as well as the inventory cost.
Transportation information include frequency of each transport vector, capacity of each one, availability, possibility to circulate, cost, particular requirements as national flag or piracy risk ….
Warehousing size and location have important consequences on several managerial decisions
Computerized treatment of all these data allows to simulate the actions and their result, allows a fast and very reactive circulation of the information between all the members of the network, reduces the redundancy of some encoding operations just as the error risk, allows a good traceability of all the decisions and operations, authorizes a real time follow-up, improves the visibility on the various sequences … Information and Communication technologies play a critical role concerning the exchange of information between suppliers, manufacturer, customers, carriers and other services providers. To be performing, every enterprise must master an information system adapted to his needs but also allowing to be networked with all the other members of the Supply chain: it is a very critical competitive advantage to be better than the competition on that aspect. But, everybody understands the major difficulty to interconnect different systems. Information must be cheap, available as soon as needed, without time lag,
1.6 Main actors
As illustrated on the figure 3, each process is requiring resources.
1.6.1 Human resources
The human resources who have an impact on the supply chain are:
q The buyers: they have to reference the suppliers who can work inside a supply chain. They must accept to work as the pilot of the supply chain decides it for the best of all the actors. The buyers must place the purchase orders when it is fixed by the Supply chain organization.
q The designers: they have to design products that it is possible to pack and transport on the best economical way. But they also must design products with the specifications that the suppliers can realize and all the actors of the supply chain can store and transport. Finally, the products must be designed with the objective to be customized at the latest stages of manufacturing.
q The packaging designers: they have to design packaging that can be economically manipulated by each member of the supply chain (size of the racks, trucks…), that correspond to the various quantities (to see §2.2) needed by the actors. It is also important that each packaging can be easily open and closed as frequently as required.
q The manufacturers: they must be flexible to accept small or large batches and evidently the must produce quality on time.
q The sellers: they must work with the precise specifications allowed by the design and with the quantities allowed by the agreement between all the parties.
q The transporters: they must deliver on time and in perfect condition.
q The warehousemen: they must act with the right diligence
q The computer operators: they must deliver the right information at the right time to the right people. Each supply chain member can recuperate the data without risk of mistake or confusion to build the appropriated management system.
1.6.2 Material resources
The material resources must be sufficient, in good conditions, available when needed and well adapted to the products and operations. These conditions are required to be able to link together many process operators. Indeed, if an operator doesn’t master well his process, it is thinkable that he will not be able to respect quality, quantity or delivery date.
This also supposes that the maintenance of all the equipments is well executed.

Load balancing RD Session host servers & Certificate error

I have three RD Session host servers Named RDSH1, RDSH2 and RDSH3.
Two servers RDSH1 and RDSH2, are user in addition to RD SH as RD CB and RD WA. I have deploy both in HE deployment with Windows NLB. RD CB and RD WA use the same url CBPub.domain.com.
I have created collection and add all three servers to that collection. I have published application, and it works. Users connect without warning to all three servers, when using RD WEB. But when user try to connect to terminal
server using mstsc and url of RCCB CBPub.domain.com, I get certificate warning only when connecting to RDSH3 server where warring is for RDSH3.domain.com. I’m probably missing something basic.
RDSH3 has in private computer store same certificate, that is deployed on all three servers. It was deploy manual prior RS SH deployment. It is the same certificate as it is installed on RDSH1 & RDSH2 server.

Hi,
Thank you for posting in Windows Server Forum.
What’s the certificate error which you are facing?
The certificate which used for RDS server must be signed by trusted authority and placed under “local computer\personal store”.
If you are just connecting internally from clients in the same domain, you should be able to use an internal Enterprise CA to create a SAN or wildcard certificate which you can use on your servers.
We need to install the certificates on all RDSH server manually.
• Open the MMC and open the Certificates snapin
• Add the Local Computer
• Import the certificate into Computer\Personal
• Open the certificate and find the thumbprint on the details tab. Copy the thumbprint to notepad and delete all the spaces.
• Open up an elevated PowerShell prompt and write:
• wmic /namespace:\\root\cimv2\TerminalServices PATH Win32_TSGeneralSetting Set SSLCertificateSHA1Hash=”‎PASTE_THUMBPRINT_STRING”
• You can check the certificate by running:
• Get-WmiObject -class “Win32_TSGeneralSetting” -Namespace root\cimv2\terminalservices -Filter “TerminalName=’RDP-tcp'”

Load balancing in Tuxedo 9.1 and RAC

Hello to all,
I have some doubts on the way of balancing load in tuxedo 9.1 and RAC (Oracle 10gR2).
Before, without RAC our configuration was the following one:
GRP_A: service A001, service A002
GRP_B: service B001, service B002
Both groups were attacking the same BBDD, Now with the configuration in RAC we have the following thing:
We have two intances RAC: ORARAC1 and ORARAC2
TUXRACGROUPS=GRP_A1, GRP_B1; GRP_A2, GRP_B2
The groups GRP_A1 = GRP_A2 and GRP_B1 = GRP_B2, but the groups GRP_A1 and GRP_B1 use the instance ORARAC1 and GRP_A2 and GRP_B2 use the instance ORARAC. Summarizing:
GRP_A1: service A001, service A002 (ORARAC1)
GRP_B1: service B001, service B002 (ORARAC1)
GRP_A2: service A001, service A002 (ORARAC2)
GRP_B2: service B001, service B002 (ORARAC2)
Have formed the variable TUXRACGROUPS=GRP_A1, GRP_B1; GRP_A2, GRP_B2
How is Tuxedo balancing the traffic?
1) Does not balance load between RACGROUPS?
2) Does it use RAC.. as favourite?
3) Does the RACGROUPS balance when it's overlaeded or always?
3) Does the same algorithm uses that LDBAL?, if this is affirmative, is it necessary to have formed in the ubb LDABL=Y?
4) Tuxedo uses an algorithm of round-robin?
5) others
I have looked for information but I have not found any information that could help to understanding it.
Thanks in advance
P.D.: Excuse my english :(

There is Oracle RAC routing information available at
http://e-docs.bea.com/tuxedo/tux91/ads/adorac.htm#248431
If you are not running in a transaction, then the TUXRACGROUPS environment
variable will not be relevant and routing will be handled as it would be if
this environment variable were not set.
Assuming that GRP_A1 and GRP_A2 are the only groups that offer services A001
and A002 and GRP_B1 and GRP_B2 are the only groups that offer services B001
and B002, routing of service requests made within a transaction will be
handled as follows:
- Any call to A001 or A002 made within a transaction with an even GTRID
counter value will be handled by GRP_A1. (The GTRID counter value is the
last of the 3 hexadecimal numbers printed in the ULOG for messages printed
within that transaction.)
- Any call to A001 or A002 made within a transaction with an odd GTRID
counter value will be handled by GRP_A2.
- Any call to B001 or B002 made within a transaction with an even GTRID
counter value will be handled by GRP_B1.
-Any call to B001 or B002 made within a transaction with an odd GTRID
counter value will be handled by GRP_B2.

Load Balance Reverse Poxy using ACE and HTTP Header Sticky

Dear all,
I have a reverse proxy that makes HTTP and HTTPS requests to an ACE.
For implement persistence I want to configure HTTP HEADER Stickyness using the X-Forwarder-For information but I don't know:
How to implement it ( I'l apreciate a little example about it).
Which values I need for OFFSET and LENGHT fields.
Can you help me please?
Thanks a lot!!

Hi Cesar.
Thanks a lot for your answer but I think you misunderstand the question or I'm not explaninig very well
I don't need to insert anything.
The serverfarm X will be accesed by a reverse proxy. This reverse proxy already inserts the X-Forearder-From header, so the request from the reverse proxy comes with this header to the serverfarm X.
The problem is that now, the serverfarm X sticky the client based on source IP. This is a wrong behavior becasue all the request comes form the same source (Reverse proxy) and all the load forwards to the same real IP address.
This is because I want to change the sticky from source IP to HTTP header and looks for the X-Forwarder-For filed.
Hop it will clarify the question!

XI Load Balance

Hi all.
My customers want to implement XI load balance using multiple WAS instances (installed on differet machine) and web dispatcher. I can't find the related installation documents in SDN.
Anyone can help me?
Thanks in advance.

Hi YiNing,
the architecture of an XI installation in load balancing depends from the flow that XI have to manage in load balancing, because the JAVA stack and the ABAP stack have different way to implement load balancing and also some adapter differs from other.
I sugget you to study all the components included in the flow you want to load banace (like "flat files-> file adapter->adapter engine->Integration engine->BPM->IDoc adapter")
Then you have to study all the components and the methods they have for load balancing. At the end you will have a clear picture and you will know better where to look and how to procced.
Your starting point is

Load Balancing 2012 R2 Session Host Collection with External Network Load Balancer

Hi,
We are moving from a 2008 R2 Remote Desktop session host deployment to 2012 R2. Previously, we used our Kemp hardware load balancer to distribute load between RDSH servers. We had a connection broker deployed so that if an existing disconnected session was
detected during the initial connection, the user was directed back to that session.
In 2012 R2, we planned to again used the Kemp load balancer to main high availability for our RDSH collection, but are experiencing strange issues. It seems that the RD Connection Broker is also performing load balancing--the result being that initial connections
to the RDSH collection may go to one RDSH server with the least connections through the Kemp, but then be redirected to a different RDSH server by the broker, even when there is no existing session for the user on that second server.
Our question is: Should we not be using the Kemp balancer at all (how would this work)? Or should we disable load balancing by the connection broker (if so...how)?
Further complicating our redirection issue with that the RDSH servers have multiple interfaces--one with public addresses and others with private. The connection broker seems to abritrarily pick among the destination RDSH server's available IP addresses
for the redirection and trying to redirect to a private address will fail. We think we have worked around this by connecting to each RDSH server from a 2008 R2 server's RDSH Configuration console and choosing just the public adapter under the Network Adapters
tab--is there no way to access this setting in 2012 R2?
Thanks in advance!
Matthew

Hi Matthew,
As you are most likely already aware, inn Remote Desktop Services 2012 / R2 the Connection broker uses round robin DNS to load balance.
To simplify things I would recommend that you let the connection broker load balance the sessions and use the KEMP to Load balance the RDweb and Gateway servers.
Have a look at the following articles:

ISE 1.3 Load Balancing

Hello,
I've got 4x ISE appliance, 2x Administration and 2x PSN
1 Administration primary / Monitoring secondary
2 Policy Service Node
3 Administration secondary / Monitoring Primary
4 Policy Service Node
Both PSN's are in the same Node Group... ISE is working fine, but it's not load balancing profiling, Corp WLAN is getting profiled by PSN 2 and guest WLAN is getting profiled by PSN 4... Is there a way to make both WLAN's to get profiled by random PSN? Like a load Balancer?
BR,
Emerson

Hi Emerson-
Do you have a load balancer? If you do you can load balance the sessions between the ISE nodes located in the node group. If not you could do Anycast based profiling. Check this link out that goes over all of the different options that you have:

I hope this helps!

Cisco 886VA - Multiple PPPoE Line Load Balancing

Dear Cisco Community,
due to the need of increased bandwidth a customer ordered three ADSL6000/576Kbit lines from the same ISP. Dial-in is done with PPPoE and the IP is not static.
- Is it possible to load balance between the three ISP lines with this router as the Cisco 886VA-K9 (Advanced IP Services) doesnt support PFR/OER I want to load balance per session, meaning each TCP session takes the same path, the next TCP session takes second path, next TCP session takes third path, then first path again and so on.
- I did read the tutorials avaiable, but they don't discuss how the lines are used in round-robin fashion, just how to distribute different traffic on different lines. (https://supportforums.cisco.com/document/32186/dual-internet-links-nating-pbr-and-ip-sla?page=1) or (http://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/100658-ios-nat-load-balancing-2isp.html)

Hey there,
I managed to fulfill my requirement..
If its a cluster on same machine or across machines, this should work
1. Login to machine, cd $DOMAIN_HOME
2. mkdir -p Apex_lsn_config/AdminServer Apex_lsn_config/<MS1> Apex_lsn_config/<MS2> # MS1 and MS2 are the Managed Server names as appropriate
#If you are planning for cluster spawning MS's across machines, make sure you create the dir's on step 2 for each machine respectively. (in my case $DOMAIN_HOME is not shared)
3. Copy apex-config.xml from the /tmp/apex or whatever location you have it currently to Apex_lsn_config/<MS1> Apex_lsn_config/<MS2>
4. cd $DOMAIN_HOME/bin; cp -p SetDomainEnv.sh SetDomainEnv.sh.orig #Backup the file
5. Append -Djava.io.tmpdir in SetDomainEnv.sh as below for JAVA_OPTIONS # Do it on both machine if you are not sharing DOMAIN_HOME and planning cluster across machines
-Djava.io.tmpdir=$DOMAIN_HOME/APEX_CONFIG/${SERVER_NAME}
Hint: Search for "iterativeDev" and append the same line with -Djava.jo.tmpdir
6. Modify "java.io.tmpdir" from the web.xml file of apex.war as below and re-deploy the war
<context-param>
<param-name>config.dir</param-name>
<param-value>${java.io.tmpdir}</param-value>
</context-param>
7. Bounce Weblogic Admin and Manged Servers. Make sure to tail the Managed Server log to see apex-config.xml is picked from the new location.
8. Brew a Coffee for yourself :)
- You find the instructions on creating a cluster from weblogic documentation, the steps mentioned above are only to overcome the bdb locking issue whilst creating a cluster.
Did it help?

CSS Load balancing for Exchange Server

Hi,
I have CSS configured in single arm and I have multiple servers configured for load balancing and it is working fine but when I am configuring Exchange server for load balancing I am facing problem and applications and printer/scanners are not able to send the email through the Virtual IP address configured for exchaneg server.
But if we configured the real server IP in the printer/scanners they are able to send the email. While checking the logs on the exchange server, it is showing that request for the email so coming from the Exchange VIP configured in the CSS.
I can telnet on port 25 on the VIP address (192.168.200.237). But unable to send the email through this VIP.
Below is the configuration
service ENOC_EXCHANGE-1

=============================================================================
Please let me know how to solve this problem. System team is saying with the physical IP address it is working fine problem with Load balancing. I have even tried with the
Add service command in the group but didnt work for me. If i will remove the group command then I cant telnet on port 25.
I think this is related to single arm modle or some wrong configuration for the NAT.
Kindly assist me

Hi
Printers are on Vlan 80 ( gw is 192.168.80.1) and exange server is on vlan 200 (gw is 192.168.200.1) i have multiple vlan which will communcate with exchange.
I hv other servers on 200 subnet which are working fine in load balancing.
My CSS is single arm setup.
Please assist
