  • How to route between 2 networks with a server with 2 network cards?

    - by LumenAlbum
    This is the first time I am faced with routing and it seems I have hit a dead end. I have the following scenario: client1: 192.168.1.10 255.255.255.0 gateway: 192.168.1.100 DNS server: 192.168.1.100 client2: 192.168.1.20 255.255.255.0 gateway: 192.168.1.100 DNS server: 192.168.1.100 server (Windows Server 2008 R2 with enabled RAS & Routing Services) network card 1 (connected to a switch along with the clients) 192.168.1.100 255.255.255.0 DNS server: 127.0.0.1 network card 2 (connected to the router) 192.168.2.100 255.255.255.0 gateway: 192.168.2.1 DNS server: 127.0.0.1 (DNS forwarding to 192.168.2.1) ISP router (with connection to internet) 192.168.2.1 Now in this scenario I have tried to route traffic from the 192.168.1.0/24 network with the clients to the 192.168.2.0/24 network with the routers to connect them to the internet. However, no matter what I do I get no positive ping to the router 192.168.2.1. Ping from 192.168.168.1.10 to 192.168.1.20: Success to 192.168.1.100: Success to 192.168.2.100: Success to 192.168.2.1: not reachable The routing table contains the 2 routes 192.168.1.0 and 192.168.2.0 as directly connected. Does anyone know where the routing fails? I have searched different forums but mostly found nothing relevant. One post however pointed out that in a similar situation the problem was that the router doesn't know the way back and the internet router would need a static route back to the first router. If that really is the case, I take it there is no solution with my equipment, because the standart ISP router doesn't allow to set any static routes.

  • Cisco ASA: How to route PPPoE-assigned subnet?

    - by Martijn Heemels
    We've just received a fiber uplink, and I'm trying to configure our Cisco ASA 5505 to properly use it. The provider requires us to connect via PPPoE, and I managed to configure the ASA as a PPPoE client and establish a connection. The ASA is assigned an IP address by PPPoE, and I can ping out from the ASA to the internet, but I should have access to an entire /28 subnet. I can't figure out how to get that subnet configured on the ASA, so that I can route or NAT the available public addresses to various internal hosts. My assigned range is: 188.xx.xx.176/28 The address I get via PPPoE is 188.xx.xx.177/32, which according to our provider is our Default Gateway address. They claim the subnet is correctly routed to us on their side. How does the ASA know which range it is responsible for on the Fiber interface? How do I use the addresses from my range? To clarify my config; The ASA is currently configured to default-route to our ADSL uplink on port Ethernet0/0 (interface vlan2, nicknamed Outside). The fiber is connected to port Ethernet0/2 (interface vlan50, nicknamed Fiber) so I can configure and test it before making it the default route. Once I'm clear on how to set it all up, I'll fully replace the Outside interface with Fiber. My config (rather long): : Saved : ASA Version 8.3(2)4 ! hostname gw domain-name example.com enable password ****** encrypted passwd ****** encrypted names name 10.10.1.0 Inside-dhcp-network description Desktops and clients that receive their IP via DHCP name 10.10.0.208 svn.example.com description Subversion server name 10.10.0.205 marvin.example.com description LAMP development server name 10.10.0.206 dns.example.com description DNS, DHCP, NTP !

  • How can I embed a youtube video using variable widths/heights for a dynamic width web page?

    - by Dan Gayle
    I want to set a youtube video to 100% width so that it scales appropriately in a dynamic width column on a web page I am designing. The problem is that the height doesn't behave like the height of an image. Instead of scaling proportionately, it either collapses (if set to "auto" or left blank) or it scales seemingly random if set to a percentage. How can I get it to remain proportionate while still dynamic?

  • Is it possible to use ASP.NET Dynamic Data and SubSonic 3?

    - by James
    Is it possible to use ASP.NET Dynamic Data with SubSonic 3 in-place of Linq to SQL classes or the Entity Framework? MetaModel.RegisterContext() throws an exception if you use the context class that SubSonic generates. I thought I remembered coming across a SubSonic/Dynamic Data example back before SubSonic 3 was released but I can't find it now. Has anyone been able to get this to work?

  • Ubuntu Server Cannot Route to the Internet

    - by ejes
    I've been having this problem for weeks now, and I can't seem to figure out the problem. My server can route the local network and serves it well, however it cannot access the internet. It can't be the router because everything else on this lan can route through the router. I've even switched the ethernet port. Any help would be appreciated. I've tried all the usual places, anyway, here are the configs: root@uhs:~# uname -a Linux uhs 3.0.0-16-generic-pae #28-Ubuntu SMP Fri Jan 27 19:24:01 UTC 2012 i686 i686 i386 GNU/Linux root@uhs:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

  • Operation times out trying to SSH outside LAN i.e. from internet to LAN no connection is established

    - by Pelle L
    I run Ubuntu 12.04 and have no success connecting with SSH from "Internet". The router is a TL-MR3420 which is set up to forward requests to one of the NIC's on ubuntu machine (which has in total 3 NICs). I can SSH from a client on the "local" network/LAN. The forward mechanism in the router seems to work. If I stop SSH service on the Ubuntu machine and instead start one on the windows machine - it works like a charm. I do not use the Std port 22 but that shouldn't be an issue as far as I understand - sine it works on the same port on the win machine. Since my public IS isn't static I use a dynDNS service but as said earlier the same setup works from the win machine. The router is located on 192.168.0.1 The Ubuntu NICs has the following IP: eth2 192.168.0.100 , eth1 192.168.0.101 , eth0 192.168.0.102 and I have forwarded the "outside" request to 192.168.0.100 In regards for firewall settings on the Ubuntu machine I have disabled the ufw and the command ufw status give status: inactive. I don't now it this is relevant information but teh command iptables --list give: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I have tried to catch traffic with help of wireshark (a tool I'm not too used to use) and it seems as a few (3?) "requests" actually reaches the NIC but ... nothing happens. The syslog does not show any entries during these attempts. Perhaps it could be some routing issues but I have reached my level of competence and are stuck ... all help and support to get this sorted out is much appreciated. I'm new to Linux so please do not assume I have a configuration that is correct - but as I wrote earlier - if the client that initiate SSH is on the LAN it all works. PS:I have also tried to get VPN (PPP) working from Internet with no success - once again VPN works on the windows machine ... so my best guess is that this is related to how the ubuntu machine handles (IP) traffic and not the TL-MR3420 router or other network issues.

  • Posting data from multiple servers routing through one server to client server

    - by Swaroop Kundeti
    I have 5 webservers behind Load balancer and we have a client server at other end. Client has white listed my 5 webserver public ip so that my webservers will post a file to the client server. Here the problem is my webservers is going to increase and i cannot always ask client to make my new webserver ip's white list. So i would like to make my infra this way, my webservers will post data to the client server routing from a single server. Like assume that web-1 is main server and the remaining 4 web servers will post data to client server routing through main web-1. I was told that this can be achieved by doing IP Tunneling. But i have no idea how to do that. Would be great for any kind of help.

  • how're routing tables populated?

    - by Robbie Mckennie
    i've been reading "tcp/ip illustrated" and i started reading about ip forwarding. all about how you can receive a datagram and work out where to send it next based on the desination ip and your routing table. but what confused me is how (in a home network setting) the table itself is populated. is there a lower layer protocol at work here? does it come along with dhcp? or is it simply based on the ip address and netmask of each interface? i do know (from other books) that in the early days of ethernet one had to set up routing tables by hand, but i know i didn't do that.

  • Routing table with two NIC adapters in libvirt/KVM

    - by lzap
    I created a virtual NAT network (192.168.100.0/24 network) in my libvirt and new guest with two interfaces - one in this network, one as bridged (10.34.1.0/24 network) to the local LAN. The reason for that is I need to have my own virtual network for my DHCP/TFTP/DNS testing and still want to access my guest externally from my LAN. On both networks I have working DHCP, both giving them IP addresses. When I setup NAT port forwarding (e.g. for ssh), I can connect to the eth0 (virtual network), everything is fine. But when I try to access the eth1 via bridged interface, I have no response. I guess I have problem with my routing table - outgoing packets are routed to the virtual NAT network (which has access to the machine I am connecting from - I can ping it). But I am not sure if this setup is correct. I think I need to add something to my routing table. # ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:B4:A7:5F inet addr:192.168.100.14 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:feb4:a75f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16468 errors:0 dropped:27 overruns:0 frame:0 TX packets:6081 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22066140 (21.0 MiB) TX bytes:483249 (471.9 KiB) Interrupt:11 Base address:0x2000 eth1 Link encap:Ethernet HWaddr 52:54:00:DE:16:21 inet addr:10.34.1.111 Bcast:10.34.1.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fede:1621/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:34 errors:0 dropped:0 overruns:0 frame:0 TX packets:189 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4911 (4.7 KiB) TX bytes:9 # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.34.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth1 0.0.0.0 192.168.100.1 0.0.0.0 UG 0 0 0 eth0 Network I am trying to connect from is different than network the hypervisor is connected to: 10.36.0.0.

I thought setting correct interface would be sufficient. What is needed to get my packets coming through?

  • Routing / binding 128 to one server

    I have a Ubuntu server with 128 ip's (static external ips 86.xx.xx.16), and I want to crawl pages thru different ip's. The gateway is xx.xxx.xxx.1, the main ip is xx.xxx.xxx.16, and the other 128 ip's are xx.xxx.xxx.129/255. I tried this configuration in /etc/network/interfaces but I doesn't work. It work if I remove the gateway for the aliases eth0:0 and eth0:1. I think this is routing problem. auto lo iface lo inet loopback auto eth0 auto eth0:0 auto eth0:1 iface eth0 inet static address xx.xxx.xxx.16 netmask 255.255.255.128 gateway xx.xxx.xxx.1 iface eth0:0 inet static address xx.xxx.xxx.129 netmask 255.255.255.128 gateway xx.xxx.xxx.1 iface eth0:1 inet static address xx.xxx.xxx.130 netmask 255.255.255.128 gateway xx.xxx.xxx.1 Also, please tell me how to "reset" every changes that I made in networking and routing. Thank you

  • Routes for IIS Classic and Integrated Mode

    - by imran_ku07
         Introduction:             ASP.NET MVC Routing feature makes it very easy to provide clean URLs. You just need to configure routes in global.asax file to create an application with clean URLs. In most cases you define routes works in IIS 6, IIS 7 (or IIS 7.5) Classic and Integrated mode. But in some cases your routes may only works in IIS 7 Integrated mode, like in the case of using extension less URLs in IIS 6 without a wildcard extension map. So in this article I will show you how to create different routes which works in IIS 6 and IIS 7 Classic and Integrated mode.       Description:             Let's say that you need to create an application which must work both in Classic and Integrated mode. Also you have no control to setup a wildcard extension map in IIS. So you need to create two routes. One with extension less URL for Integrated mode and one with a URL with an extension for Classic Mode.   routes.MapRoute( "DefaultClassic", // Route name "{controller}.aspx/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); routes.MapRoute( "DefaultIntegrated", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults );               Now you have set up two routes, one for Integrated mode and one for Classic mode. Now you only need to ensure that Integrated mode route should only match if the application is running in Integrated mode and Classic mode route should only match if the application is running in Classic mode. For making this work you need to create two custom constraint for Integrated and Classic mode. So replace the above routes with these routes,     routes.MapRoute( "DefaultClassic", // Route name "{controller}.aspx/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { mode = new ClassicModeConstraint() }// Constraints ); routes.MapRoute( "DefaultIntegrated", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { mode = new IntegratedModeConstraint() }// Constraints );            The first route which is for Classic mode adds a ClassicModeConstraint and second route which is for Integrated mode adds a IntegratedModeConstraint. Next you need to add the implementation of these constraint classes.     public class ClassicModeConstraint : IRouteConstraint { public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { return !HttpRuntime.UsingIntegratedPipeline; } } public class IntegratedModeConstraint : IRouteConstraint { public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { return HttpRuntime.UsingIntegratedPipeline; } }             HttpRuntime.UsingIntegratedPipeline returns true if the application is running on Integrated mode; otherwise, it returns false. So routes for Integrated mode only matched when the application is running on Integrated mode and routes for Classic mode only matched when the application is not running on Integrated mode.       Summary:             During developing applications, sometimes developers are not sure that whether this application will be host on IIS 6 or IIS 7 (or IIS 7.5) Integrated mode or Classic mode. So it's a good idea to create separate routes for both Classic and Integrated mode so that your application will use extension less URLs where possible and use URLs with an extension where it is not possible to use extension less URLs. In this article I showed you how to create separate routes for IIS Integrated and Classic mode. Hope you will enjoy this article too.   SyntaxHighlighter.all()

  • How would you mask data returned in a Dynamic Data for Entities website?

    - by David Stratton
    I'm doing this in Visual Studio 2008, not 2010, in case there is a relevant difference between the two versions of the Dynamic Data websites. How would I mask data in the automatically generated tables in a Dynamic Data for Entities website? The scenario is we have one table where we want to allow users to ENTER sensitive data, but not VIEW sensitive data, so... (In the list below, I'm using "template" to mean "The web page generated automatically based on the schema and action. I'm sure that's the wrong terminology, but the meaning should be clear.) The "Insert" template should have the field's textbox available for the user to type a value in. The "Edit" template should have the field's textbox blanked out (empty string) regardless of what was in the field in the database in the first place, but the user should be able to type in new data and have it save The "View" template should either have the data for this field masked, or non-visible. The auto-generated table showing the list of records should also have this field masked or non-visible. I can do this easily with standard Web Forms, but I'm having a hard time figuring this out in the Dynamic Data site I'm working on. Masking data is such a common task, I have to believe Microsoft thought of this and provided a way to do it...

  • Flash CS 4 / AS 2 + Dynamic Text + Html + Embedded fonts...

    - by AndreMiranda
    I have this scenario: 1) I have a dynamic text that receives its data from a XML. 2) The texts showed get theirs style from a CSS file. 3) My dynamic text has a html 'span' tag and it's formatted according to the CSS class that it's passed via the XML file. Ok... so far so good. It's something like: _root.txt.txtDica = "<span class='"+ node.childNodes[_global.auxCont].attributes.myStyle +"'>" + node.childNodes[_global.auxCont].attributes.myText+ "</span>"; The problem is that the swf has a poor quality text. So, I've been looking around, found some things about embedded fonts, Flash TextField() and etc. But, nothing seems to work. Does anyone know how can I generate this html tag in a dynamic text with a good quality? It's worth to say that I'm using regular fonts, such as Verdana and Arial. Thanks a lot!

  • What are some ways to accomplish a dynamic array?

    - by Ted
    I'm going to start working on a new game and one of the things I'd like to accomplish is a dynamic array sort of system that would hold map data. The game will be top-down 2d and made with XNA 4.0 and C#. You will begin in a randomized area which will essentially be tile based. As such a 2 dimensional array would be one way to accomplish this by holding numerical values which would correspond to a list of textures and that would be how it would draw this randomly created map. The problem is I would kind of only like to create the area around where you start and they could venture in which ever direction they wanted to. This would mean I'd have to populate the map array with more randomized data in the direction they go. I could make a really large array and use the center of it and the rest would be in anticipation of new content to be made, but that just seems very inefficient. I suppose when they start a new game I could have a one time map creation process that would go through and create a large randomly generated map array, but holding all of in memory at all times seems also inefficient. Perhaps if there was a way that I'd only hold parts of that map data in memory at one time and somehow not hold the rest in memory. In the end I only need to have a chunk of the map somewhat close to them in memory so perhaps some of you might have suggestions on good ways to approach this kind of randomized map and dynamic array problem. It wouldn't need to be a dynamic array type of thing if I made it so that it pulled in map data nearby that is needed and then once off the screen and not needed it could somehow get rid of that memory that way I wouldn't have a huge array taking up a bunch of memory.

  • Building a project in VS that depends on a static and dynamic library

    - by fg nu
    Noob noobin'. I would appreciate some very careful handholding in setting up an example in Visual Studio 2010 Professional where I am trying to build a project which links: a previously built static library, for which the VS project folder is "C:\libjohnpaul\" a previously built dynamic library, for which the VS project folder is "C:\libgeorgeringo\" These are listed as Recipes 1.11, 1.12 and 1.13 in the C++ Cookbook. The project fails to compile for me with unresolved dependencies (see details below), and I can't figure out why. Project 1: Static Library The following are the header and source files that were compiled in this project. I was able to compile this project fine in VS2010, to the named standard library "libjohnpaul.lib" which lives in the folder ("C:/libjohnpaul/Release/"). // libjohnpaul/john.hpp #ifndef JOHN_HPP_INCLUDED #define JOHN_HPP_INCLUDED void john( ); // Prints "John, " #endif // JOHN_HPP_INCLUDED // libjohnpaul/john.cpp #include <iostream> #include "john.hpp" void john( ) { std::cout << "John, "; } // libjohnpaul/paul.hpp #ifndef PAUL_HPP_INCLUDED #define PAUL_HPP_INCLUDED void paul( ); // Prints " Paul, " #endif // PAUL_HPP_INCLUDED // libjohnpaul/paul.cpp #include <iostream> #include "paul.hpp" void paul( ) { std::cout << "Paul, "; } // libjohnpaul/johnpaul.hpp #ifndef JOHNPAUL_HPP_INCLUDED #define JOHNPAUL_HPP_INCLUDED void johnpaul( ); // Prints "John, Paul, " #endif // JOHNPAUL_HPP_INCLUDED // libjohnpaul/johnpaul.cpp #include "john.hpp" #include "paul.hpp" #include "johnpaul.hpp" void johnpaul( ) { john( ); paul( ); Project 2: Dynamic Library Here are the header and source files for the second project, which also compiled fine with VS2010, and the "libgeorgeringo.dll" file lives in the directory "C:\libgeorgeringo\Debug". // libgeorgeringo/george.hpp #ifndef GEORGE_HPP_INCLUDED #define GEORGE_HPP_INCLUDED void george( ); // Prints "George, " #endif // GEORGE_HPP_INCLUDED // libgeorgeringo/george.cpp #include <iostream> #include "george.hpp" void george( ) { std::cout << "George, "; } // libgeorgeringo/ringo.hpp #ifndef RINGO_HPP_INCLUDED #define RINGO_HPP_INCLUDED void ringo( ); // Prints "and Ringo\n" #endif // RINGO_HPP_INCLUDED // libgeorgeringo/ringo.cpp #include <iostream> #include "ringo.hpp" void ringo( ) { std::cout << "and Ringo\n"; } // libgeorgeringo/georgeringo.hpp #ifndef GEORGERINGO_HPP_INCLUDED #define GEORGERINGO_HPP_INCLUDED // define GEORGERINGO_DLL when building libgerogreringo.dll # if defined(_WIN32) && !defined(__GNUC__) # ifdef GEORGERINGO_DLL # define GEORGERINGO_DECL _ _declspec(dllexport) # else # define GEORGERINGO_DECL _ _declspec(dllimport) # endif # endif // WIN32 #ifndef GEORGERINGO_DECL # define GEORGERINGO_DECL #endif // Prints "George, and Ringo\n" #ifdef __MWERKS__ # pragma export on #endif GEORGERINGO_DECL void georgeringo( ); #ifdef __MWERKS__ # pragma export off #endif #endif // GEORGERINGO_HPP_INCLUDED // libgeorgeringo/ georgeringo.cpp #include "george.hpp" #include "ringo.hpp" #include "georgeringo.hpp" void georgeringo( ) { george( ); ringo( ); } Project 3: Executable that depends on the previous libraries Lastly, I try to link the aforecompiled static and dynamic libraries into one project called "helloBeatlesII" which has the project directory "C:\helloBeatlesII" (note that this directory does not nest the other project directories). The linking process that I did is described below: To the "helloBeatlesII" solution, I added the solutions "libjohnpaul" and "libgeorgeringo"; then I changed the properties of the "helloBeatlesII" project to additionally point to the include directories of the other two projects on which it depends ("C:\libgeorgeringo\libgeorgeringo" & "C:\libjohnpaul\libjohnpaul"); added "libgeorgeringo" and "libjohnpaul" to the project dependencies of the "helloBeatlesII" project and made sure that the "helloBeatlesII" project was built last. Trying to compile this project gives me the following unsuccessful build: 1------ Build started: Project: helloBeatlesII, Configuration: Debug Win32 ------ 1Build started 10/13/2012 5:48:32 PM. 1InitializeBuildStatus: 1 Touching "Debug\helloBeatlesII.unsuccessfulbuild". 1ClCompile: 1 helloBeatles.cpp 1ManifestResourceCompile: 1 All outputs are up-to-date. 1helloBeatles.obj : error LNK2019: unresolved external symbol "void __cdecl georgeringo(void)" (?georgeringo@@YAXXZ) referenced in function _main 1helloBeatles.obj : error LNK2019: unresolved external symbol "void __cdecl johnpaul(void)" (?johnpaul@@YAXXZ) referenced in function _main 1E:\programming\cpp\vs-projects\cpp-cookbook\helloBeatlesII\Debug\helloBeatlesII.exe : fatal error LNK1120: 2 unresolved externals 1 1Build FAILED. 1 1Time Elapsed 00:00:01.34 ========== Build: 0 succeeded, 1 failed, 2 up-to-date, 0 skipped ========== At this point I decided to call in the cavalry.

  • Coarse Collision Detection in highly dynamic environment

    - by Millianz
    I'm currently working a 3D space game with A LOT of dynamic objects that are all moving (there is pretty much no static environment). I have the collision detection and resolution working just fine, but I am now trying to optimize the collision detection (which is currently O(N^2) -- linear search). I thought about multiple options, a bounding volume hierarchy, a Binary Spatial Partitioning tree, an Octree or a Grid. I however need some help with deciding what's best for my situation. A grid seems unfeasible simply due to the space requirements and cache coherence problems. Since everything is so dynamic however, it seems to be that trees aren't ideal either, since they would have to be completely rebuilt every frame. I must admit I never implemented a physics engine that required spatial partitioning, do I indeed need to rebuild the tree every frame (assuming that everything is constantly moving) or can I update the trees after integrating? Advice is much appreciated - to give some more background: You're flying a space ship in an asteroid field, and there are lots and lots of asteroids and some enemy ships, all of which shoot bullets. EDIT: I came across the "Sweep an Prune" algorithm, which seems like the right thing for my purposes. It appears like the right mixture of fast building of the data structures involved and detailed enough partitioning. This is the best resource I can find: http://www.codercorner.com/SAP.pdf If anyone has any suggestions whether or not I'm going in the right direction, please let me know.

  • How-to get the binding for a tab in the Dynamic Tab Shell Template

    - by Frank Nimphius
    The Dynamic Tab Shell template does expose a method on the Tab.java class that allows you to get access to the ADF binding container for a tab. At least in theory this works, because in practice this call always returns a null value (a bug is filed for this). To work around the problem, you can use code similar to the following to get the ADF binding for a specific tab DCBindingContainer currentBinding = (DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry(); DCBindingContainer templateBinding = (DCBindingContainer)currentBinding.get("ptb1"); DCBindingContainer tabBinding= (DCBindingContainer)templateBinding.get("r"+0);  In the code line above, the tabBinding variable will hold the binding reference to the first tab in the dynamic tab shell template. Note that the tab doesn't need to be visible for this (which has to do with how the template works).  "ptb1" is the template reference name in the PageDef file (Executable section) of the template consumer view. Check this string in your page before using this code. If it differs, change it also in the code above. "r0" is the binding reference of the first tab in the template. Te last tab is referenced by "r14".

  • Dynamic Monitoring Service (DMS) Configuration Dumping and CPU Utilization

    - by ShawnBailey
    There was recently a report of CPU spikes on a system that were occuring at precise 3 hour intervals. Research revealed that the spikes were the result of the Dynamic Monitoring Service generating a metrics dump and writing it under the server 'logs' folder for every WLS server in the domain. This blog provides some information on what this is for and how to control it. The Dynamic Monitoring Service is a facility in FMw (JRF to be more precise) that collects runtime data on the components deployed to WebLogic. Each component is responsible for how much or how little they use the service and SOA collects a fair amount of information. To view what is collected on any running server you can use the following URL, http://host:port/dms/Spy and login with admin credentials. DMS is essentially always running and collecting this information in the runtime and to protect against loss of this data it also runs automatic backups, by default at the 3 hour interval mentioned above. Most of the management options for DMS are exposed through WLST but these settings are not so we must open the dms_config.xml file which can be found in DOMAIN_HOME/config/fmwconfig/servers/<server_name>/dms_config.xml. The contents are fairly short and at the bottom you will find the following entry: <dumpConfiguration>     <dump intervalSeconds="10800" maxSizeMBytes="75" enabled="true"/> </dumpConfiguration> The interval of 10800 seconds corresponds to the 3 hours and the maximum size is 75MB. The file is written as an archive to DOMAIN_HOME/servers/<server_name>/logs/metrics. This archive contains the dump in XML format. You can disable the dumps all together by simply setting the 'enabled' value to 'false' or of course you could modify the other parameters to suit your needs. Disabling the dumps will NOT impact DMS collections or display at runtime. It will only eliminate these periodic backups.
