• Semaphore - What is the use of initial count?

  - by Sandbox

  http://msdn.microsoft.com/en-us/library/system.threading.semaphoreslim.aspx To create a semaphore, I need to provide an initial count and maximum count. MSDN states that an initial count is - The initial number of requests for the semaphore that can be granted concurrently. While it states that maximum count is The maximum number of requests for the semaphore that can be granted concurrently. I can understand that the maximum count is the maximum number of threads that can access a resource concurrently. But, what is the use of initial count? If I create a semaphore with an initial count of 0 and a maximum count of 2, none of my threadpool threads are able to access the resource. If I set the initial count as 1 and maximum count as 2 then only thread pool thread can access the resource. It is only when I set both initial count and maximum count as 2, 2 threads are able to access the resource concurrently. So, I am really confused about the significance of initial count? SemaphoreSlim semaphoreSlim = new SemaphoreSlim(0, 2); //all threadpool threads wait SemaphoreSlim semaphoreSlim = new SemaphoreSlim(1, 2);//only one thread has access to the resource at a time SemaphoreSlim semaphoreSlim = new SemaphoreSlim(2, 2);//two threadpool threads can access the resource concurrently

• Limiting object allocation over multiple threads

  - by John

  I have an application which retrieves and caches the results of a clients query. The client then requests different chunks of data and the application sends the relevant results and removes them from the cache. A new requirement for this application is that there needs to be a run-time configurable maximum number of results which may be cached. I've taken the naive approach and implemented this by using a counter under a lock which is incremented every time a result is cached and decremented whenever a result is removed from the cache. Unfortunately, this has drastically reduced the applications performance when processing a large number of concurrent requests. I have tried both a critical section lock and spin-lock; the performance improves a bit with a spin-lock, but is still unacceptably slow. Is there a better way to solve this problem which may improve performance? Right now I have a thread pool that services requests and each request is tied to a Request object which stores that cached results for that particular request. Here is a simplified pseudo code version of my current implementation: void ResultCallback( Result result, Request *request ) { lock totalResultsCached lock cachedLimit if( totalResultsCached + 1 > cachedLimit ) { unlock cachedLimit unlock totalResultsCached //cancel the request return; } ++totalResultsCached; unlock cachedLimit unlock totalResultsCached request.add(result) } void SendResults( int resultsToSend, Request *request ) { while ( resultsToSend > 0 ) { send(request.remove()) lock totalResultsCached --totalResultsCached unlock totalResultsCached --resultsToSend; } }

• How to synchronize access to many objects

  - by vividos

  I have a thread pool with some threads (e.g. as many as number of cores) that work on many objects, say thousands of objects. Normally I would give each object a mutex to protect access to its internals, lock it when I'm doing work, then release it. When two threads would try to access the same object, one of the threads has to wait. Now I want to save some resources and be scalable, as there may be thousands of objects, and still only a hand full of threads. I'm thinking about a class design where the thread has some sort of mutex or lock object, and assigns the lock to the object when the object should be accessed. This would save resources, as I only have as much lock objects as I have threads. Now comes the programming part, where I want to transfer this design into code, but don't know quite where to start. I'm programming in C++ and want to use Boost classes where possible, but self written classes that handle these special requirements are ok. How would I implement this? My first idea was to have a boost::mutex object per thread, and each object has a boost::shared_ptr that initially is unset (or NULL). Now when I want to access the object, I lock it by creating a scoped_lock object and assign it to the shared_ptr. When the shared_ptr is already set, I wait on the present lock. This idea sounds like a heap full of race conditions, so I sort of abandoned it. Is there another way to accomplish this design? A completely different way?

• How can I [simply] consume JSON Data to display to the page

  - by Atomiton

  I usually use JSON with jQuery to just return a string with html. However, I want to start to use Javascript objects in my code. What's the simplest way to get started using json objects on my page? Here's a sample Ajax call ( after $(document).ready( { ... }) of course: $('#btn').click(function(event) { event.preventDefault(); var out = $('#result'); $.ajax({ url: "CustomerServices.asmx/GetCustomersByInvoiceCount", success: function(msg) { // // Iterate through the json results and spit them out to a page? // }, data: "{ 'invoiceCount' : 100 }" }); }); My WebMethod: [WebMethod(Description="Gets customers with more than n invoices")] public List<Customer> GetCustomersByInvoiceCount(int? invoiceCount) { using (dbDataContext db = new dbDataContext()) { return db.Customers.Where(c => c.InvoiceCount >= invoiceCount); } } What gets returned: {"d":[{"__type":"Customer","Account":"1116317","Name":"SOME COMPANY","Address":"UNit 1 , 392 JOHN ST. ","LastTransaction":"\/Date(1268294400000)\/","HighestBalance":13922.34},{"__type":"Customer","Account":"1116318","Name":"ANOTHER COMPANY","Address":"UNIT #345 , 392 JOHN ST. ","LastTransaction":"\/Date(1265097600000)\/","HighestBalance":549.42}]} What I'd LIKE to know, is what are people generally doing with this returned json? Do you iterate through the properties and create an html table on the fly? Is there way to "bind" JSON data using a javascript version of reflection ( something like the .Net GridView Control ) Do you throw this returned data into a Javascript Object and then do something with it? An example of what I want to achieve is to have an plain ol' html page ( on a mobile device )with a list of a Salesperson's Customers. When one of those customers are clicked, the customer id gets sent to a webservice which retrieves the customer details that are relevant to a sales person. I know the SO talent pool is quite deep so I figured you all here would be able to guide in the right direction and give me a few ideas on the best way to approach this.

• What is causing this template-related compile error? (c++)

  - by Setien

  When I try to compile this: #include <map> #include <string> template <class T> class ZUniquePool { typedef std::map< int, T* > ZObjectMap; ZObjectMap m_objects; public: T * Get( int id ) { ZObjectMap::const_iterator it = m_objects.find( id ); if( it == m_objects.end() ) { T * p = new T; m_objects[ id ] = p; return p; } return m_objects[ id ]; } }; int main( int argc, char * args ) { ZUniquePool< std::string > pool; return 0; } I get this: main.cpp: In member function ‘T* ZUniquePool<T>::Get(int)’: main.cpp:12: error: expected `;' before ‘it’ main.cpp:13: error: ‘it’ was not declared in this scope I'm using GCC 4.2.1 on Mac OS X. It works in VS2008. I'm wondering whether it might be a variation of this problem: http://stackoverflow.com/questions/1364837/why-doesnt-this-c-template-code-compile But as my error output is only partially similar, and my code works in VS2008, I am not sure. Can anyone shed some light on what I am doing wrong?

  - by jmfayard

  so I'm trying to run for the first time the nginx web server with php5-fpm on a debian wheezy server Hitting a php file display simply File not found I have done my research (waste a lot of hours actually ;), there are a lot of people that have similar problems, yet I didn't succeed to correct it with what worked for them. I still have the same error : $ tail /var/log/nginx/access.log /var/log/nginx/error.log /var/log/php5-fpm.log | less == /var/log/nginx/error.log <== 2013/10/26 21:36:00 [error] 6900#0: *1971 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, I have tried a lot of things, it's hard to remember what.

• PHP suddenly failed after IIS update

  - by James Hay

  All my application pools were stopped this morning after I got to work. I can restart them, but when I try to load the website the app pool crashes again. Update: I've looked in the GAC as the error below suggests and it seems that the file is not there. How do I get it back? Update 2: I found a further error in the event log saying The Module name FastCgiModule path C:\WINDOWS\System32\inetsrv\iisfcgi.dll returned an error from registration. The data is the error. So following the information from here http://forums.iis.net/t/1153937.aspx I removed CGI and my sites are working again. This has fixed the initial problem, but now I don't have FastCGI so I'm fairly sure that PHP will no longer be working (I don't have any PHP at the moment to test). Original Post I'm getting this error in the event viewer: IISMANAGER_ERROR_LOADING_PROVIDER_TYPE IIS Manager could not load type 'Web.Management.PHP.PHPProvider, Web.Management.PHP, Version=1.2.0.0, Culture=neutral, PublicKeyToken=8175de49a9aec91d' for module provider 'PHP' that is declared in %windir%\system32\inetsrv\config\administration.config.

• ASA hairpining: I basicaly want to allow 2 spokes to be able to communicate with each other.

  - by Thirst4Knowledge

  ASA Spoke to Spoke Communication I have been looking at spke to spoke comms or "hairpining" for months and have posted on numerouse forums but to no avail. I have a Hub and spoke network where the HUB is an ASA Firewall version 8.2 * I basicaly want to allow 2 spokes to be able to communicate with each other. I think that I have got the concept of the ASA Config for example: same-security-traffic permit intra-interface access-list HQ-LAN extended permit ip ASA-LAN 255.255.248.0 HQ-LAN 255.255.255.0 access-list HQ-LAN extended permit ip 192.168.99.0 255.255.255.0 HQ-LAN 255.255.255.0 access-list no-nat extended permit ip ASA_LAN 255.255.248.0 HQ-LAN 255.255.255.0 access-list no-nat extended permit ip HQ-LAN 255.255.255.0 192.168.99.0 255.255.255.0 access-list no-nat extended permit ip 192.168.99.0 255.255.255.0 HQ-LAN 255.255.255.0 I think my problem may be that the other spokes are not CIsco Firewalls and I need to work out how to do the alternative setups.

• LVM mirror attempt results in "Insufficient free space"

  - by MattK

  Attempting to add a disk to mirror an LVM volume on CentOS 7 always fails with "Insufficient free space: 1 extents needed, but only 0 available". Having searched for a solution, I have tried specifying disks, multiple logging options, adding 3rd log partition, but have not found a solution Not sure if I am making a rookie mistake, or there is something more subtle wrong (I am more familiar with ZFS, new to using LVM): # lvconvert -m1 centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --mirrorlog mirrored --alloc anywhere centos_bi/home /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home /dev/sdi2 /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available The two disks are of the same size, and have identical partition layouts via "sfdisk -d /dev/sdi part_table; sfdisk /dev/sda < part_table".

• Oracle Application Server Performance Monitoring and Tuning (CPU load high)

  - by Berkay

  Oracle Application Server Performance Monitoring and Tuning (CPU load high) i have just hired by a company and my boss give me a performance issue to solve as soon as possible. I don't have any experience with the Java EE before at the server side. Let me begin what i learned about the system and still couldn't find the solution: We have an Oracle Application Server (10.1.) and Oracle Database server (9.2.), the software guys wrote a kind of big J2EE project (X project) using specifically JSF 1.2 with Ajax which is only used in this project. They actively use PL/SQL in their code. So, we started the application server (Solaris machine), everything seems OK. users start using the app starting Monday from different locations (app 200 have user accounts,i just checked and see that the connection pool is set right, the session are active only 15 minutes). After sometime (2 days) CPU utilization gets high,%60, at night it is still same nothing changed (the online user amount is nearly 1 or 2 at this time), even it starts using the CPU allocated for other applications on the same server because they freed If we don't restart the server, the utilization becomes %90 following 2 days, application is so slow that end users starts calling. The main problem is software engineers say that code is clear, and the System and DBA managers say that we have the correct configuration,the other applications seems OK why this problem happens only for X application. I start copying the DB to a test platform and upgrade it to the latest version, also did in same with the application server (Weblogic) if there is a bug or not. i only tested by myself only one user and weblogic admin panel i can track the threads and dump them. i noticed that there are some threads showing as a hogging. when i checked the manuals and control the trace i see that it directs me the line number where PL/SQL code is called from a .java file. The software eng. says that yes we have really complex PL/SQL codes but what's the relation with Application server? this is the problem of DB server, i guess they're right... I know the question has many holes, i'd like to give more in detail but i appreciate the way you guide me. Thanks in advance ... Edit: The server both in CPU and Memory enough to run more complex applications

• How do I get a .Net 4.0 app to coexist as an application under a SharePoint 2007 website in IIS v7?

  - by Craig Nakamoto

  I have created a small .Net 4.0 website and installed it on my SharePoint server as a separate web site in IIS v7 (using port 8008 for now). I had to install the .Net 4 framework, set up the database, etc. and this all went smoothly and my app works as a standalone website. Now I am trying to get pages from my website to show up in SharePoint 2007. For various reasons (the SharePoint site is using SSL, security, etc.) I now need to move my .Net app to run under the SharePoint 2007 site in IIS. I have added it as an 'Application' and set it up with the same .Net v4 application pool and settings that were working when it was set up as a standalone site. Now when I try to access the application I get the error at the end of this description. Any help would be greatly appreciated. I already tried following the instructions on this post: http://blogs.msdn.com/sgoodyear/archive/2007/05/07/custom-web-applications-coexisting-with-sharepoint-2007.aspx but that did not help. Thanks!

• Install MegaCli to Monitor Perc 5/i in Nexentastor 3

  - by Peter Valadez

  I have a Dell 2950 with a Perc 5/i Raid controller that we've already installed Nexentastor 3 Community Edition on. We setup a raid-10 array that and put a ZFS pool on top of the hardware. As I understand, in this configuration ZFS/Nexentastor will not be able to tell when a disk fails in the array. Obviously, this is not optimal. Since the Dell Perc 5/i controller is a rebranded LSI controller, you should be able to use the MegaCli utility to manage the array and monitor its condition. I had seen in a separate forum that the Perc 5/i is very similar to the LSI MegaRAID 8480E, so I tried installing the MegaCli utility at the link below. However, I have not been able to successfully install the utility. http://www.lsi.com/support/products/Pages/MegaRAIDSAS8480E.aspx Here is what happened when I tried to install MegaCli: root@Nexenta2:/files# pkgadd -d MegaCli.pkg Warning: unable to relocate '$BASEDIR' mv: cannot move `solmegacli-8.02.16/' to a subdirectory of itself, `solmegacli-8.02.16//var/lib/dpkg/alien/solmegacli/reloc/solmegacli-8.02.16' mv: cannot move `solmegacli-8.02.16/' to a subdirectory of itself, `solmegacli-8.02.16//opt/solmegacli-8.02.16' 822-date: warning: This program is deprecated.

I've got three questions: Is it possible to install and use MegaCli in Nexentastor 3? If so, how can I install MegaCli on Nexentastor 3? Suggestions welcome!!! If not, is there a better way to monitor the condition of the Perc 5/i hardware raid? Our 2950 does have a DRAC card, so can I use that to monitor the raid condition?

• vSphere Client vCenter Template Customization Specification Using Windows Sysprep Unattended Answer XML File

  - by Brian

  I'm trying to setup a vSphere Client vCenter v5.0.0 Build 455964 Template Customization Specification using a Windows Sysprep unattended answer XML file for Win2008R2. However I didn't know how Sysprep worked before attempting this so it was a time-consuming nightmare (even after reviewing VMware vSphere ESXi 5's documentation)! I think I've figure out what I'm supposed to be doing, but it's still not working. The biggest problem at this point is that vSphere Client vCenter Customization Specification IP address information is not sticking when I load a Sysprep XML file with just 1 basic setting! This can only be a bug. Here is the process I'm using: PROCESS for Windows - vSphere Client Install Windows OS install VM Tools customize Windows (GPOs can be used to do this after deployment) install Applications (GPOs can be used to do this after deployment too) shutdown the VM convert the VM to a template create a custom Windows Sysprep XML answer file with desired customizations View Management Customization Specifications Manager create "New" Specification for "Target Virtual Machine OS" select Windows check "Use Custom Sysprep Answer File" (ADDS: Custom Sysprep File. KEEPS: Network (IP), Operating System Options (SID, Sysprep /generalize). REPLACES: Registration Information of Owner Name & Organization, Computer Name, Windows License (Key), Administrator Password, Time Zone, Run Once, Workgroup or Domain) name it as "VMwareCS-OS####R#x32/64w/Sysprep-TEST" (CS=Customization Specification) set Description as "Created YYYY/MM/DD by FLast" NEXT import a Sysprep answer file from secure location NEXT Custom settings NEXT click "..." box to right of "Use DHCP" set "Use the following IP settings:" for "IP Address" fill out the first 2 octets set appropriate values for other 2-3 fields set DNS server addresses OK NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish View Inventory VMs and Templates right-click previously completed template Deploy Virtual Machine from this Template provide the new OS name (max15char) select inventory location NEXT select Host/Cluster (wait for validation to succeed) NEXT select Resource Pool (wait for validation to succeed) NEXT select Storage location NEXT check "Power on this virtual machine after creation" select "Customize using an existing customization specification" select desired specification select "Use the Customization Wizard to temporarily adjust the specification before deployment" NEXT NEXT Custom settings? NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish Finish. I know a community member named "brian" (http://serverfault.com/users/25904/brian) has worked with this scenario before, but I couldn't figure out how to contact him directly, so Brian if you see this message could you provide some information to help? Thanks, Brian

• multiple webapps in tomcat -- what is the optimal architecture?

  - by rvdb

  I am maintaining a growing base of mainly Cocoon-2.1-based web applications [http://cocoon.apache.org/2.1/], deployed in a Tomcat servlet container [http://tomcat.apache.org/], and proxied with an Apache http server [http://httpd.apache.org/docs/2.2/]. I am conceptually struggling with the best way to deploy multiple web applications in Tomcat. Since I'm not a Java programmer and we don't have any sysadmin staff I have to figure out myself what is the most sensible way to do this. My setup has evolved through 2 scenarios and I'm considering a third for maximal separation of the distinct webapps. [1] 1 Tomcat instance, 1 Cocoon instance, multiple webapps -tomcat |_ webapps |_ webapp1 |_ webapp2 |_ webapp[n] |_ WEB-INF (with Cocoon libs) This was my first approach: just drop all web applications inside a single Cocoon webapps folder inside a single Tomcat container. This seemed to run fine, I did not encounter any memory issues. However, this poses a maintainability drawback, as some Cocoon components are subject to updates, which often affect the webapp coding. Hence, updating Cocoon becomes unwieldy: since all webapps share the same pool of Cocoon components, updating one of them would require the code in all web applications to be updated simultaneously. In order to isolate the web applications, I moved to the second scenario. [2] 1 Tomcat instance, each webapp in its dedicated Cocoon environment -tomcat |_ webapps |_ webapp1 | |_ WEB-INF (with Cocoon libs) |_ webapp1 | |_ WEB-INF (with Cocoon libs) |_ webapp[n] |_ WEB-INF (with Cocoon libs) This approach separates all webapps into their own Cocoon environment, run inside a single Tomcat container. In theory, this works fine: all webapps can be updated independently. However, this soon results in PermGenSpace errors. It seemed that I could manage the problem by increasing memory allocation for Tomcat, but I realise this isn't a structural solution, and that overloading a single Tomcat in this way is prone to future memory errors. This set me thinking about the third scenario. [3] multiple Tomcat instances, each with a single webapp in its dedicated Cocoon environment -tomcat |_ webapps |_ webapp1 |_ WEB-INF (with Cocoon libs) -tomcat |_ webapps |_ webapp2 |_ WEB-INF (with Cocoon libs) -tomcat |_ webapps |_ webapp[n] |_ WEB-INF (with Cocoon libs) I haven't tried this approach, but am thinking of the $CATALINA_BASE variable. A single Tomcat distribution can be multiply instanciated with different $CATALINA_BASE environments, each pointing to a Cocoon instance with its own webapp. I wonder whether such an approach could avoid the structural memory-related problems of approach [2], or will the same issues apply? On the other hand, this approach would complicate management of the Apache http frontend, as it will require the AJP connectors of the different Tomcat instances to be listening at different ports. Hence, Apache's worker configuration has to be updated and reloaded whenever a new webapp (in its own Tomcat instance) is added. And there seems no way to reload worker.properties without restarting the entire Apache http server. Is there perhaps another / more dynamic way of 'modularizing' multiple Tomcat-served webapps, or can one of these scenarios be refined? Any thoughts, suggestions, advice much appreciated. Ron

• IIS6 Virtual Directory 500 Error on Remote Share

  - by David

  We have our servers at the server farm in a domain. Let's call it LIVE. Our developer computers live in a completely separate corporate domain, miles and miles away. Let's call it CORP. We have a large central storage unit (unix) that houses images and other media needed by many webservers in the server farm. The IIS application pools run as (let's say) LIVE\MediaUser and use those credentials to connect to a central storage share as a virtual directory, retrieve the images, and serve them as if they were local on each server. The problem is in development. On my development machine. I log in as CORP\MyName. My IIS 6 application pool runs as Network Service. I can't run it as a user from the LIVE domain because my machine isn't (and can not be) joined to that domain. I try to create a virtual directory, point it to the same network directory, click Connect As, uncheck the "Always use the authenticated user's credentials when validating access to the network directory" checkbox so that I can enter the login info, enter the credentails for LIVE\MediaUser, click OK, verify the password, etc. This doesn't work. I get "HTTP Error 500 - Internal server error" from IIS. The IIS log file reports sc-status = 500, sc-substatus = 16, and sc-win32-status = 1326. The documentation says this means "UNC authorization credentials are incorrect" and the Win32 status means "Logon failure: unknown user name or bad password." This would be all and good if it were anywhere close to accurate. I double- and trouble-checked it. Tried multiple known good logins. The IIS manager allows me to view the file tree in its window, it's only the browser that kicks me out. I even tried going to the virtual directory's Directory Security tab, and under Authentication and Access Control, I tried using the same LIVE domain username for the anonymous access credential. No luck. I'm not trying to run any ASP, ASP.NET, or other dynamic anything out of the virtual directory. I just want IIS to be able to load static images, css, and js files. If anyone has some bright ideas I would be most appreciative!

• long access times and errors in iis application

  - by user55862

  I am having an issue with an IIS application (details of environment at the end of the message). The web site works great most of the time and I cannot reproduce any error in our test system. On the live system however with on averare of 5-15 requests per second I have a problem with that some requests (about 0.05%) will take over 300 seconds to complete. The other requests complete withing 5-10 seconds. It seem like if all the errornous requests end up with a Timer_EntityBody error in the error log. I have never seen this as an end user but I guess that they will receive some kind of error message. I am trying to find out what can be causing this errornous behaviour. Any ideas are welcome. I have read something about that there can be an MTU issue if ICMP and MTU protocols are blocked in the firewall. Does that sound reasonable? I have also read about updating to IIS 7 should do the trick. Does it sound reasonable? I think that the problem has another cause but I have no idea of what. I have tried running hte perormance monitor, monitoring for database locks and active transaction counts. I can see some of these in the perfmon log for the MSSQL server (another machine) for example: Active transactions is sometimes peaking and sometimes for long periods Lock waits per seconds is sometimes peaking Transactions per second is sometimes peaking Page IO Latch wait is sometimes peaking Lock wait time (ms) is sometimes peaking But I cannot see that any of these correlate to the errors in the IIS error log. On the IIS server machine I can also see with perfmon that some values peak a few times during a day: Request execution time Avg disk queue length I can neither see that any of these correlate to the errors in the IIS error log. In the below code I have anonymized by replacing some parts with HIDDEN The following can be seen in the access log 2010-10-01 08:35:05 W3SVC1301873091 **HIDDEN** POST /**HIDDEN**/Modules/BalanceModule.aspx - 80 - **HIDDEN** Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) ASP.NET_SessionId=**HIDDEN** 400 0 64 0 2241 127799 At the same time the following can be seen in the error log: 2010-10-01 08:35:05 **HIDDEN** 1999 **HIDDEN** 80 HTTP/1.0 POST /**HIDDEN**/Modules/BalanceModule.aspx - 1301873091 Timer_EntityBody Test+Pool I can tell the following about the environment: Server: Windows Server 2003 x64 SP2 running on VMWare HTTP Server: IIS v6.0 with ASP.NET 2.0.50727 Antivirus: Trend Micro OfficeScan (Is it a good idea to have this on a server?)

• Issues with Server 2012 using DFSR running on Hyper-V 2012

  - by Bryan

  We have a number of Server 2012 systems, all of which run virtualised on Hyper-V 2012 server. We are having problems with two such virtual instances, both of which are used as file servers, whereby they occasionally stop responding to requests to serve files to clients. After logging on to the server, attempts to shut it down gracefully fail (no error, it just fails to acknowledge a shutdown request). Recovery is a case of power cycling the server(s) from the Hyper-V console. These two servers don't server a large number of users (one serves no more than 6 users, and the other serves around 20 users), they are in the same domain, but on different physical hardware (and at different sites). They don't lock up at the same time. They both use DFSR to replicate a fairly large amount of data between themselves (200GB) over ADSL connections, this is working fine, and we have been using DFSR to do this on the previous two generations of server OS we have used (Server 2008 R2 and Server 2003 - both of which were physical installs however). Today, when one of the servers crashed, I noticed an entry in the event log, which looked similar to the following: Log Name: Application Source: ESENT Date: 27/11/2012 10:25:55 Event ID: 533 Task Category: General Level: Warning Keywords: Classic User: N/A Computer: HAL-FS-01.example.com Description: DFSRs (1500) \\.\E:\System Volume Information\DFSR\database_C8CC_101_CC00_EC0E\ dfsr.db: A request to write to the file "\\.\E:\System Volume Information\ DFSR\database_C8CC_101_CC00_EC0E\fsr.log" at offset 4423680 (0x0000000000438000) for 4096 (0x00001000) bytes has not completed for 36 second(s). This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. When the server started up again, I went to find the event log entry to investigate further and found that the event log entry was no longer there (I assume it was in memory but failed to write to disk before the server was powered off, for the reason mentioned in the message). I found the above message by searching back further in the event log. Both of these virtual servers have their E: volumes fully allocated as opposed to dynamically expanding, and there are no other issues on any of the other virtual servers (which include server 2012, server 2008 R2 and Ubuntu 12.04 x64). There are no signs of IO, memory or CPU starvation on the host systems. I've used performance counters on the affected virtual servers to monitor memory usage (including non paged pool usage), as well as CPU and network utilisation, and none of these show any signs of trouble when the issue arises. I would have thought our configuration isn't that uncommon, so I'm wondering if anyone else has seen this, and managed to resolve the problem?

• IIS can't load Oracle.Web assembly (for ASP.NET membership provider)

  - by Konamiman

  I am trying to configure an IIS web site to use an Oracle database for ASP.NET membership, but I can't get it to work. IIS doesn't seem to be able to load the assembly containing the Oracle membership provider. That's what I have so far: An Oracle 10g database online and with all the tables for ASP.NET membership created. Windows 2008 R2 Standard with the web server role installed, including support for ASP.NET. Oracle 11g Release 2 ODAC 11.2.0.1.2 installed. The installed components are: Oracle data provider for .NET, Oracle providers for ASP.NET, Oracle instant client. The default web site on IIS (I am using that for testing) has the following web.config file: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <membership defaultProvider="OracleMembershipProvider"> <providers> <remove name="SqlMembershipProvider" /> <add name="OracleMembershipProvider" type="Oracle.Web.Security.OracleMembershipProvider, Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342" connectionStringName="OracleServer" /> </providers> </membership> </system.web> </configuration> (Additional attributes on the "add" element omitted for brevity. Also, the connection string is defined for the whole server.) The Oracle.Web.dll file is on the GAC. That's the relevant part of the C:\Windows\Assembly folder: The web site application pool is configured for .NET 2.0, and has 32-bit applications enabled. I have allowed untrusted providers in the IIS' administration.config file (just for the sake of testing, I'll explicitly add the assembly to the trusted providers list later). With all of this setup in place, when I click on the ".NET Users" icon on the IIS manager, I get a warning about the provider having too much privileges, and when I accept I get the following message: There was an error while performing this operation. Details: Could not load file or assembly 'Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified. So, what am I missing? How can I get the Oracle membership provider to work? Thank you! UPDATE: It seems that the problem is not with IIS itself, but with the IIS administrator only. When using the web site configuration tool provided by Visual Studio, everything works fine.

• DPM 2010 "Disk failed or disk not found"

  - by SysAdmin

  I have an HP Proliant ML110 G5 server with Windows server 2008R2 only dedicated for DPM 2010. This server has a limit in HD of 8TB which has already been met. I'm now stuck in this situation where my disk keeps failing "Disk failed or Disk not found" in the disk management. Only after I reboot the system the disk comes back up. Today I was running my monthly tape backup on a certain protection group and the disk failed again while the tape job was running (so the job wasn't completed). This is the description of the error in the alerts: "The disk Disk 1 - Hitachi HDS722020ALA330 SCSI Disk Device cannot be detected or has stopped responding. All subsequent protection activities that use this disk will fail until the disk is brought back online. (ID 3120)". My backup system is becoming useless! I don't think that is a hardware issue (please correct me if I'm wrong) since the HD works fine for a certain period of time which is becoming shorter and shorter. I basically have no more option to fix this problem. I tried to fix any error that was coming up in the event viewer with no luck (included one regarding the SQL2008 compatibility issue). The disk keeps failing! Now I'm only trying to recover/migrate the data from the disk that is having problem but my issue now is that I cannot add any drives to my server since I already got installed the maximum storage capacity 8TB. I thought about 2 simple options. Please tell me what you guys think about it; Unplug one of the 2 storage pool disks (disk0, that one without problem) from the machine and install a new one in order to migrate the data with the Migration tool for DPM. Remove the defective disk (disk1), put back the disk0 and run the synchronization/consistency check on all the groups to recreate replicas and recovery points. Run diskpart.exe and clean up the disk (loosing all data) and hoping that he will work after I sync all the protection groups. Both solutions are not elegant but I have no better options at the moment. Please I need some help. Thanks for your time Angelo

• Issues getting a Cisco WLC 5508 to find AIR-LAP1142N

  - by user95917

  hoping someone can help me with a problem here. I'm attempting to setup a test (loan from Cisco) wireless network. Here's what i've got/done: 5508 Controller - Service Port IP set to 10.74.5.2 /24. Management IP set to 10.74.6.2 /24 with a default gateway of 10.74.6.1. Virtual IP set to 1.1.1.1. Copper SFP in slot 7, CAT5 (known good) going from there to port 1/0/47 on the switch. Green lights on both ends. 2960-S Switch - Vlan1 - 10.74.6.1 /24. dhcp pool 10.74.6.0 /24, default router 10.74.6.1. excluded-address 10.74.6.1, 10.74.6.2. 1/0/4 on the switch is set to switchport mode access and no shut. 1/0/47 on the switch is setup to switchport mode trunk and no shut. 1/0/4 has a CAT5 (known good) cable going from there to the AP. When I do a sh cdp nei from the switch, i can see the AP and Controller listed. When i configure my PC's nic to 10.74.5.5, and plug a cable from my nic to the SP port on the controller i can get on the device via the gui. In there, the only errors/info that show up in the trap are: Link Up: Slot: 0 Port: 7 Controller time base status - Controller is out of sync with the central timebase. I've manually set the time but apparently that's not quite the problem (or at least not the entire problem). When i plug the AP in, i see on the switch console that it grants it power, it sees it connect...but the controller won't see it for some reason. From what i've read you shouldn't have to do anything to the AP as it's managed by the controller...but i'm not sure what setting I'm missing for it to work. The AP light on top is continually cycling green, red, yellow. When I first start it up, it blinks green for 20 or so seconds, then goes to solid green for another 20 seconds or so, then flashes blue, green, red for awhile...but always ends up goinn back to the standard, green, red, yellow. Does anyone see any obvious issues with my setup or have any suggestions as to why i might be having a problem? Thanks for your help!

• Setting Timeouts: SQL Server 2008/IIS 7.5

  - by Julie

  We have recently migrated from a Win 2003/SQL Server 2000 system to Win 2008 64 bit R2, SQL Server 2008 R2. Our websites are in classic asp, and this can't be changed to another scripting language at this time. On the old server, if I got stuck in some kind of endless loop, the page would throw an error. On the new server, I have a page that has some sort of looping problem, that even though the SQL SP is called only once (and runs fine run as a query on the server) it pegs SQL server and therefore locks all of our websites. I'll get my code figured out, no biggie. But I need to make sure the server times out when this happens. (The page I'm working on runs fine with certain instances of the query, and locks with others using a different query variable. I can't have something like that sneak up on me on a page I haven't touched for three years.) I can't figure out how an SP that runs once on the server, from an ASP page, is tying up SQL server this way. It's obviously some sort of a timeout issue, but I can't figure out where/which timeout values to change. I actually have to remote desktop to the server and kill the process in SQL server. I'm afraid I'm a generalist, and server management is not my thing, even though it's my responsibility, so I am almost certain to have questions about any answer that I receive. How can I track this down? What settings do I need to change? More info: It's not SQL Server On our test site, I created an ASP file that just did an endless loop (do while 1=1) and had the same problem - the other websites wouldn't load - without SQL server being involved. So I think the reason the process was hanging is that the page wasn't timing out as it should, and so the connection to SQL was never closed. Killing the process in SQL server would reset the page somehow. For my intentional endless loop, I had to refresh the app pool to get rid of it. This points more to either IIS or the ASP settings. The ASP timeouts are set to whatever the default were when the server was first loaded. I still can't figure out why one file is locking up all websites, though. Again, that didn't happen on the old server.

• OpenVPN Clients using server's connection (with no default gateway)

  - by Branden Martin

  I wanted an OpenVPN server so that I could create a private VPN network for staff to connect to the server. However, not as planned, when clients connect to the VPN, it's using the VPN's internet connection (ex: when going to whatsmyip.com, it's that of the server and not the clients home connection). server.conf local <serverip> port 1194 proto udp dev tun ca ca.crt cert x.crt key x.key dh dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt client-to-client keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 9 client.conf client dev tun proto udp remote <srever> 1194 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert x.crt key x.key ns-cert-type server comp-lzo verb 3 Server's route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 69.64.48.0 * 255.255.252.0 U 0 0 0 eth0 default static-ip-69-64 0.0.0.0 UG 0 0 0 eth0 default static-ip-69-64 0.0.0.0 UG 0 0 0 eth0 default static-ip-69-64 0.0.0.0 UG 0 0 0 eth0 Server's IP Tables Chain INPUT (policy ACCEPT) target prot opt source destination fail2ban-proftpd tcp -- anywhere anywhere multiport dports ftp,ftp-data,ftps,ftps-data fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:20000 ACCEPT tcp -- anywhere anywhere tcp dpt:webmin ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:www ACCEPT tcp -- anywhere anywhere tcp dpt:imaps ACCEPT tcp -- anywhere anywhere tcp dpt:imap2 ACCEPT tcp -- anywhere anywhere tcp dpt:pop3s ACCEPT tcp -- anywhere anywhere tcp dpt:pop3 ACCEPT tcp -- anywhere anywhere tcp dpt:ftp-data ACCEPT tcp -- anywhere anywhere tcp dpt:ftp ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- 10.8.0.0/24 anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain fail2ban-proftpd (1 references) target prot opt source destination RETURN all -- anywhere anywhere Chain fail2ban-ssh (1 references) target prot opt source destination RETURN all -- anywhere anywhere My goal is that clients can only talk to the server and other clients that are connected.

• OpenVPN, Great on Windows, VERY slow on Mac...

  - by Phsion

  Hello, I'm not really an IT Pro, but this seemed like the best place to ask this question... I have setup VPN networks in the past, for fun, and everything was great, but now I've set one up for my boss, and while my computers all work great, his Mac machines are almost too slow to work with. Its pretty much vanilla configs all around, anyone have any ideas? Its a TUN routing setup over UDP. Back Story: My boss travels a lot, and wants to be able to access all his files from the road, and is also pretty paranoid about security (even though knows almost nothing about computers). SO i figured a VPN would be the answer. I went with OpenVPN, but there are some other issues. The only ISP we can get in our area besides Dial-UP is a crappy Satellite provider, that doesn't offer public IPs unless your willing to pay, so while the computers and VPN setup are pretty vanilla, the routing and structure is strange to get around this limitation. Specs: Its OpenVPN2, and there are six machines using it (only three actually use it, the rest are my test machines), one Windows 7 laptop, two XP Desktops, one OS X 10.5 Desktop, one 10.6 Desktop, and one 10.6 Laptop. One XP Desktop sits at my house and acts as the server (6Mbs/2Mbs FIOS connection). One XP desktop sits at the office and hosts a webpage that will wake up the Main Mac Desktop from sleep, and also ping all the machines on the VPN and show their status. The main office mac (10.6) stays in sleep mode until it gets the Wake-On-Lan packet from the Office XP, and then it auto connects to the VPN and opens itself up. The reason for all this is the Satellite private IP crap means i cant directly access the office machines outside of the LAN, so everyone connects to my house first, then they talk to each other from there. The Wake On Lan weirdness is because my boss doesn't want to leave the main Mac on all the time, and making a quick and dirty webpage was the easiest way to send a Magic Packet from inside the LAN without confusing my boss. The VPN uses Client Config files to make static IPs for the client. The only thing i found in google was some changes to the VPN MTU settings (down to 1400) but no real help. Oh, and i forgot...all the windows machines just have OpenVPN start as a service. The Mac laptop uses tunnelblick (an OpenVPN GUI) and the Mac Desktops use OpenVPN in normal command line mode.

• The server rejected the session-establishment request: WCF hosted on IIS

  - by Dave Hanna

  Background: I'm working on a project where we have about a dozen distinct WCF services implemented in an IIS application, communicating over net.tcp on the default port (808), using the Microsoft Net.Tcp Port Sharing Service. I recently added a self-test method to the base class of each of these services so that I could remotely hit the service and get back a status string verifying that it was in operation. We implement this app in a ladder of environments - Development, QA, UAT, and finally production. My problem: My test program, which instantiates a connection to each service in turn and invokes the self-test method, works fine on all the environments below production. We recently moved the app to production, and I'm getting a weird error that I can't explain: On the first of the services that I hit, I get back an exception: "The server at [URL] rejected the session-establishment request". All the other services respond fine. I initially thought there was something wrong with the particular service that was failing, but I tried rearranging the list of services into a different order, and it SEEMS to always be the first service that I hit that fails. (I say SEEMS because it think once in the early iterations of testing, I saw it happen on the second service that it hit. But I haven't been able to reproduce that.) I've looked at application startup delays, and that doesn't seem to be the problem, because I can come back and run the test again as soon as it finishes - a delay of only a minute or two - and get the same error. Also, in the lower level environments, there is a start up delay of probably 30 seconds to a minute, but the result still comes back as expected. I've tried accessing the services over http from INetManager, and I get intermittent failures on all the services - a particular service will return a yellow screen of death on on invocation, then come up with the expected link to the WSDL on the next one seconds later. I'm completely at a loss to explain this behavior, or how to resolve it. I've googled the error message, and not found anything helpful. It may be a configuration issue - the production servers are newly provisioned VM's, and we may not have the config exactly right (whereas all the lower level environments have been running this and other similar apps for some time), but I have not idea what to look for. I've looked at the properties of the app pool that the app is running on and compared it to the lower level environments without finding any differences. If somebody can point me in the right direction, you would have my undying gratitude.
