Dynamic EndPoint allocation in OpenESB?
I have created an EJB Service Unit and added it as a JBI module in my Service Assembly. My Ejb SU will call external webservice as a part of its functionality.
My Questions is , Is there any way in OpenESB where you can read the URL for the External WebService dynamically ?? I know this question has been posted earlier. and a wiki page is referenced in solution.
I didnt understand it properly.
Can someone Help me in this ??
Thank you
Rajesh
openESB doesn't (as of date) provide a repository to query for the URLs that applications want to use. Dynamic service feature enables the applications to call services dynamically, given that the applications have enough information during runtime as to which service they want to call. In static service composition, all the things are known at design time. Dynamic service feature could be used for use cases where the service addresses are not known during the design time. This doesn't include provisioning some sort of repository for the URLs that the applications want use.
Hope that helps,

Dynamic endpoint resolution in OpenESB
Hi,
I was wondering whether OpenESB also supports dynamic resolution of target endpoints. My impression so far is that I need to explicitly specify all connections from service consumers to service providers in a service assembly's jbi.xml deployment descriptor using the CASA editor in NetBeans. However, one of the strengths of the NMR in my opinion is that it can dynamically resolve endpoints to send message exchanges to. However, this would mean that the SA's jbi.xml must not contain any <connection>s, doesn't it? Does OpenESB's NMR support this at all? I would really like to be able to deploy a service consumer to a service engine without needing to explicitly specify the name of the endpoint providing the consumed service but instead specify the service interface name only letting the NMR resolve this to a matching endpoint at runtime.
Regards,
KaiHi Kai,
The BPEL SE supports dynamic endpoints allowing you to programatically (in the flow) change the port name, service name and address info. I've modified my flows to call an internal AddressResolution flow that calls a EJB in the Java EE SE that looks up address info from a DB. It works great but took a while to get rights as the Namespaces have to be perfect when assigning the XML to the Partner Link.
See: http://wiki.open-esb.java.net/Wiki.jsp?page=DynamicPartnerLinks

Dynamic endpoints - NullPointerException
Hi,
I'm trying to work with dynamic endpoints. I'm doing it the same way as in the DynamicPartnerLink sample. First copy literal XML-skeleton of EndpointReference in a variable, copy address and name into that variable, then copy the variable to the partner link.
When I run it, the variable is setup correctly, but the copy to the partner link causes a NullPointerException:

Anyone have an idea?

KoenHello,
When I replace the .NET 2.0 Web service dynamically called from my BPEL flow with a BEA WebLogic 8.1.5 Web service, and try to change the endpoint dynamically, I get a similar but different exception:
(note: WSDL, partnerlink, variables all replaced for calling WebLogic Web service, only endpoint is dynamic)

Queue of arrays without dynamic memory allocation
Hey folks,
I'm working on optimizing a timing critical VI. This VI is the
producer in a producer consumer architecture. I'm trying to populate
a queue from file in a manner that is as efficient as possible. My
current plan of attack is:
- read block of data from file and populate array (pre-allocated).
- add array (always of the same size) to Queue with a max size defined
(e.g. 50 elements)
- This is in a while loop as is the standard producer consumer model.
To improve the performance I would like to ensure that there is no
dynamic memory allocation on the Queue's behalf. This is easily done,
from what I understand, if the data type in the queue is of the same
type (e.g. double, int). However, since the size of an array can vary
does this mean that any queue of arrays will always dynamically
allocate memory? Is there a way to ensure that the queue will always
use the same memory as in a circular queue?
Thanks,
SteveDuplicate.

Templates and Dynamic Memory Allocation Templates
Hi , I was reading a detailed article about templates and I came across the following paragraph
template<class T, size_t N>
class Stack
T data[N]; // Fixed capacity is N
size_t count;
public:
void push(const T& t);
};"You must provide a compile-time constant value for the parameter N when you request an instance of this template, such as *Stack<int, 100> myFixedStack;*
Because the value of N is known at compile time, the underlying array (data) can be placed on the run time stack instead of on the free store.
This can improve runtime performance by avoiding the overhead associated with dynamic memory allocation.
Now in the above paragraph what does
"This can improve runtime performance by avoiding the overhead associated with dynamic memory allocation." mean ?? What does template over head mean ??
I am a bit puzzled and i would really appreciate it if some one could explain to me what this sentence means thanks...The run-time memory model of a C or C++ program consists of statically allocated data, automatically allocated data, and dynamically allocated data.
Data objects (e.g. variables) declared at namespace scope (which includes global scope) are statically allocated. Data objects local to a function that are declared static are also statically allocated. Static allocation means the storage for the data is available when the program is loaded, even before it begins to run. The data remains allocated until after the program exits.
Data objects local to a function that are not declared static are automatically allocated when the function starts to run. Example:
int foo() { int i; ... } Variable i does not exist until function foo begins to run, at which time space for it appears automatically. Each new invocation of foo gets its own location for i independent of other invocations of foo. Automatic allocation is usually referred to as stack allocation, since that is the usual implementation method: an area of storage that works like a stack, referenced by a dedicated machine register. Allocating the automatic data consists of adding (or subtracting) a value to the stack register. Popping the stack involves only subtracting (or adding) a value to the stack register. When the function exits, the stack is popped, releasing storage for all its automatic data.
Dynamically allocated storage is acquired by an explicit use of a new-expression, or a call to an allocation function like malloc(). Example:
int* ip = new int[100]; // allocate space for 100 integers
double* id = (double*)malloc(100*sizeof(double)); // allocate space for 100 doublesDynamic storage is not released until you release it explicitly via a delete-expression or a call to free(). Managing the "heap", the area from where dynamic storage is acquired, and to which it is released, can be quite time-consuming.
Your example of a Stack class (not to be confused with the program stack that is part of the C or C++ implementation) uses a fixed-size (that is, fixed at the point of template instance creation) automatically-allocated array to act as a stack data type. It has the advantage of taking zero time to allocate and release the space for the array. It has the disadvantages of any fixed-size array: it can waste space, or result in a program failure when you try to put N+1 objects into it, and it cannot be re-sized once created. -
Degree in Dynamic memory allocation need help!

Dynamic IP allocation by Radius server
Hi community,
Can Cisco Radius server allocation different IP pools for requests from difference source IP addresses but having the same username/ password information? We have multiple GGSNs using dynamic IP allocation by Radius server. In Radius server, we configure username is subscriber's MSISDN. So we face a situation that a subscriber can go through any GGSN but for different GGSN, Radius server return different IP pools, even for the same subscriber. Is it possible?
Thanks and regards,
HieuI'm not sure if the Autonomous APs have the option for AAA Override. On the WLC, I can go into the BSSID, Security, Advanced, and there's a checkbox that I would check to allow a Radius server to send back the VLAN.
I did a little research and it looks like the 1300 may give this option but instead is defined as "VLAN Override". I've found the release notes for 12.3(7)JA5 (not sure what version you're running) that give mention and a link to configuring EAP on page 4: http://www.ciscosystems.ch/en/US/docs/wireless/access_point/1300/release/notes/o37ja5rn.pdf

Dynamic Endpoint Error on asynchronous callback - Error ORABPEL-08022

Setting dynamic endpoints in ESB
Hi
I have a async BPEL process(P1). It is invoking a sync ESB services(say E1). Then the BPEL process waits in a 'Receive' activity.
The E1 ESB service contains a DB adapter tht calls a stored procedure, which performs some complex logic. After the time consuming processing is done, it writes data to a Queue. Now there is another ESB service(E2) tht reads from this queue.
After reading from the queue, the ESB service transforms the data and uses a SOAP external service to call the BPEL prcs(P1) tht is waiting in a receive activity ( as described above) .. ...
And then the BPEL replies to client..
The above process can be summarised as :
BPEL_______________________________________________ESB
P1
(Invoke) -----------------------------------request-------------------------> E1 (sync) ----->Uses DB adapter to call stored proc
| <----------------------------------response----------------------
|
(Receive)<---------------------Invokes BPEL prcs----------------------- E2 <---------------- Queue
|
In E2 service , the BPEL WSDL location is mentioned(hard coded) in the SOAP service and the E2 services always invokes the process P1
I was wondering if the following is possible :
The queue data contains the WSDL URL(end-point dtls) along with other process related details. Is it possible tht the ESB service reads this endpoint info and then the endpoint in the SOAP external service is assigned so that the E2 service is able to dynamically invoke the BPEL process....
In the design described above, the E2 service is always invoking the same BPEL service..... Please suggest if it is possible to dynamically set endpoints in ESB based on the data in the queue....or any other way ESB can invoke a prcs based on the queue data....
Thanks

all,
i was required to manually edit a service's wsdl in order to declare faulting.
by manually editing the wsdl it is no longer directly related to the service,
requiring me to use the @jws:wsdl annotation. the problem that i'm having is
that the endpoint location is now static in the wsdl. does anyone know of a means
by which i can make the <service> section dynamic in the wsdl? i need a way to
make the location of the service transparent to consumers who are internal to
our enterprise, ie as we move applications through various envs dev, test, acpt,
prod, etc.. any pointers/recommendations would be greatly appreciated.

Dynamic memory allocation failure
Dear reader,
We sometimes have a problem where our windows 2012 r2 RDS virtual servers, that reside on windows 2012r2 hyper-v hosts, loose their dynamic memory and only have their startup memory left to work with. Users start complaining that things are very slow etc.
If I check several screens (RDS Broker load balancing, hyper-v manager, cluster manager and the vm's task manager) it's clear that the vm only has its startup memory allocated. I'm not sure if this happens instantly or immidiatly after the nightly reboot.
To resolve the problem we have to call all users on the vm where it happens and ask them to logoff (if they are even able to), and then we reboot the machine.
I have checked the logs from the machine where the VM resides on and the logs from the vm itself. But I cannot find anything. We also have alot of windows 2008r2 vm's with dynamivc memory, but none of those have ever had this problem.
Searched the internet, but so far it seems we are only.
Can anyone give me a lead to troubleshoot this?
Best regards,
Ruud Boersma
MCITP Enterprise administratorHi all,
I'm going to be "one of those people" who revives dead posts for something that is relevant but obviously not fixed... sorry in advance!
We have the exact same situation, a bunch of RDSH guests with Dynamic memory turned on (60+ of them). every day between 1-8 of them will fail to allocate Dynamic memory and will be stuck on their startup RAM amount. This really hurts our users at peak
times.
I have engaged our TAM and have raised a case with PSS, Usual story "your the only one with this problem". Which obviously isn't true.
So, we have tons of free RAM on the hosts, 600GB+ on most of them, the issue affects RDSH hosts at random, across multiple hosts and clusters.
The screen shots attached are of one of our hosts from this morning. it has 8GB startup, 8GB minimum, 32GB Maximum RAM configured, with a 23% buffer. the host has 752GB RAM FREE. Notice how the perf counter "Hyper-V Dynamic Memory Integration Service"
is reporting "0", it should be reporting "32768". also under task manager on the VM we are missing "Maximum memory" which should be just below "Hardware reserved" in the bottom right hand corner.
Looks like the balloon driver is being delayed at boot time, we are going to XPerf all the servers in the hope that we can catch the critter. It's an unusual problem.
We only have Acrobat PDF viewer, word viewer, excel viewer and two custom dot.NET applications installed on the guests. Some of the servers are also just dumb RDSH hosts, with not connection broker configured, using an F5 loadbalancer for load distribution
and session management. All guests are 2012R2 patched up to March 2015, integration Services are installed and up to date (its an enlightened OS remember). -

Dynamic memory allocation on HP-UX for multiple instances on one host
Hi everyone,
I was wondering what the current possibilities are nowadays on running multiple SAP instances on one very large host with regard to resource sharing. Normally, for each instance, using PHYS_MEMSIZE etc you have to set the memory to a fixed size and then optimize it.
Preferrably we would like the memory to be allocated based upon actual usage. Is that possible at all? on HP-UX? Using third party techniques?
Thank you
Marcel RabeHello Marcel,
As Juan said you may not be able to change the parameters at runtime.
The only parameters that can be dynamically switched are :
ztta/roll_first
ztta/roll_extension
ztta/roll_area
abap/heap_area_dia
abap/heap_area_nondia
abap/heap_area_total
em/stat_log_size_MB
em/stat_log_timeout
These parameters would put a cap on memory allocations, however they wouldn't help increase the total addressable memory area.
I would suggest that you consider Adaptive Computing for dynamic use of resources.

Hi,
Anyone know of any way to dynamically set the endpoint URI property of an ALSB business service from the payload ?
Hanx!Hi Paul,
Well that looks like the explanation of the context variables of ALSB. Now I tried to override the transport/uri element of the $outbound variable in the process of dynamic routing. Unfortunately it doesn't seem to work. I want to know (first of all), is it possible to make the endpoint URI(http://mydevenv/service for example) completely dynamic, so that I wouldn't be needing any business services? Or I'd only provide the names of the business services like "BusinessService1" dynamically picked up at runtime? Well the second approach still demands that I'd have to create many number of business services or will have to change the URI each and everytime in the ALSB artifact. Kindly advice! I've been trying a way around to do this for a while and running out of help!!! Many thanks!
