  • Generating the SQL query plan takes 5 minutes, the query itself runs in milliseconds. What's up?

    - by TheImirOfGroofunkistan
    I have a fairly complex (or ugly depending on how you look at it) stored procedure running on SQL Server 2008. It bases a lot of the logic on a view that has a pk table and a fk table. The fk table is left joined to the pk table slightly more than 30 times (the fk table has a poor design - it uses name value pairs that I need to flatten out. Unfortunately, it's 3rd party and I cannot change it). Anyway, it had been running fine for weeks until I periodically noticed a run that would take 3-5 minutes. It turns out that this is the time it takes to generate the query plan. Once the query plan exists and is cached, the stored procedure itself runs very efficiently. Things run smoothly until there is a reason to regenerate and cache the query plan again. Has anyone seen this? Why does it take so long to generate the plan? Are there ways to make it come up with a plan faster?

  • Building "isolated" and "automatically updated" caches (java.util.List) in Java.

    - by Aidos
    Hi Guys, I am trying to write a framework which contains a lot of short-lived caches created from a long-living cache. These short-lived caches need to be able to return their entier contents, which is a clone from the original long-living cache. Effectively what I am trying to build is a level of transaction isolation for the short-lived caches. The user should be able to modify the contents of the short-lived cache, but changes to the long-living cache should not be propogated through (there is also a case where the changes should be pushed through, depending on the Cache type). I will do my best to try and explain: master-cache contains: [A,B,C,D,E,F] temporary-cache created with state [A,B,C,D,E,F] 1) temporary-cache adds item G: [A,B,C,D,E,F] 2) temporary-cache removes item B: [A,C,D,E,F] master-cache contains: [A,B,C,D,E,F] 3) master-cache adds items [X,Y,Z]: [A,B,C,D,E,F,X,Y,Z] temporary-cache contains: [A,C,D,E,F] Things get even harder when the values in the items can change and shouldn't always be updated (so I can't even share the underlying object instances, I need to use clones). I have implemented the simple approach of just creating a new instance of the List using the standard Collection constructor on ArrayList, however when you get out to about 200,000 items the system just runs out of memory. I know the value of 200,000 is excessive to iterate, but I am trying to stress my code a bit. I had thought that it might be able to somehow "proxy" the list, so the temporary-cache uses the master-cache, and stores all of it's changes (effectively a Memento for the change), however that quickly becomes a nightmare when you want to iterate the temporary-cache, or retrieve an item at a specific index. Also given that I want some modifications to the contents of the list to come through (depending on the type of the temporary-cache, whether it is "auto-update" or not) and I get completly out of my depth. Any pointers to techniques or data-structures or just general concepts to try and research will be greatly appreciated. Cheers, Aidos

  • Need help profiling .NET caching extension method.

    - by rockinthesixstring
    I've got the following extension Public Module CacheExtensions Sub New() End Sub Private sync As New Object() Public Const DefaultCacheExpiration As Integer = 1200 ''# 20 minutes <Extension()> Public Function GetOrStore(Of T)(ByVal cache As Cache, ByVal key As String, ByVal generator As Func(Of T)) As T Return cache.GetOrStore(key, If(generator IsNot Nothing, generator(), Nothing), DefaultCacheExpiration) End Function <Extension()> Public Function GetOrStore(Of T)(ByVal cache As Cache, ByVal key As String, ByVal generator As Func(Of T), ByVal expireInSeconds As Double) As T Return cache.GetOrStore(key, If(generator IsNot Nothing, generator(), Nothing), expireInSeconds) End Function <Extension()> Public Function GetOrStore(Of T)(ByVal cache As Cache, ByVal key As String, ByVal obj As T) As T Return cache.GetOrStore(key, obj, DefaultCacheExpiration) End Function <Extension()> Public Function GetOrStore(Of T)(ByVal cache As Cache, ByVal key As String, ByVal obj As T, ByVal expireInSeconds As Double) As T Dim result = cache(key) If result Is Nothing Then SyncLock sync If result Is Nothing Then result = If(obj IsNot Nothing, obj, Nothing) cache.Insert(key, result, Nothing, DateTime.Now.AddSeconds(expireInSeconds), cache.NoSlidingExpiration) End If End SyncLock End If Return DirectCast(result, T) End Function End Module From here, I'm using the extension is a TagService to get a list of tags Public Function GetTagNames() As List(Of String) Implements Domain.ITagService.GetTags ''# We're not using a dynamic Cache key because the list of TagNames ''# will persist across all users in all regions. Return HttpRuntime.Cache.GetOrStore(Of List(Of String))("TagNamesOnly", Function() _TagRepository.Read().Select(Function(t) t.Name).OrderBy(Function(t) t).ToList()) End Function All of this is pretty much straight forward except when I put a breakpoint on _TagRepository.Read(). The problem is that it is getting called on every request, when I thought that it is only to be called when Result Is Nothing Am I missing something here?

  • Could not continue scan with NOLOCK due to data movement during installation

    - by dbdev1
    I am running Windows Server 2008 Standard Edition R2 x64 and I installed SQL Server 2008 Developer Edition. All of the preliminary checks run fine (Apart from a warning about Windows Firewall and opening ports which is unrelated to this and shouldn't be an issue - I can open those ports). Half way through the actual installation, I get a popup with this error: Could not continue scan with NOLOCK due to data movement. The installation still runs to completion when I press ok. However, at the end, it states that the following services "failed": database engine services sql server replication full-text search reporting services How do I know if this actually means that anything from my installation (which is on a clean Windows Server setup - nothing else on there, no previous SQL Servers, no upgrades, etc) is missing? I know from my programming experience that locks are for concurrency control and the Microsoft help on this issue points to changing my query's lock/transactions in a certain way to fix the issue. But I am not touching any queries? Also, now that I have installed the app, when I login, I keep getting this message: TITLE: Connect to Server ------------------------------ Cannot connect to MSSQLSERVER. ------------------------------ ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

I have disabled Windows Firewall temporarily. I have checked the instance name against the error logs. Please advise on both of these errors. I think these two errors are related. Thanks

  • Dynamic ARP Entries turning into Static ARP entries

    - by Zach
    I recently acquired a client that has a strange ARP caching issue on one of thier servers. I have a server that will eventually start turning it's dynamic ARP entries into static ARP entries. This causes problems because when the machine that has a static ARP entries on this server receives a new IP via DHCP, then the server is not able to communicate with the clients. Clearing the ARP cache resolves the issue and the server is fine for about a week and then it starts slowly turning ARP entries into static ARP entries. I haven't narrowed it down to when or how many it starts to do, but slowly you start seeing 1 static ARP and then 5 and then 10. The server in question is a Windows Server 2003 SP2. It is a DC, DHCP, and DNS server. I've checked the DHCP scope options and there's nothing in there that would indicate anything to do with static ARP entries. The only thing different between this DNS server and our other DNS server is that the 'Dynamically Update DNA A and PTR records for DHCP clients that do not request updates' is checked on the problematic server. I've done a bit of research about this and it seems that this may happen if any PXE type services are running, from what I can tell, there is nothing running a PXE server. I'm a bit lost as I have never seen dynamic ARP entries start to turn into static ARP entries. Right now my solution is a schedule task that runs every 24 hours to clear the ARP cache (arp -d *). I would like to not rely on this schedule task. Has anybody seen this before or have any suggestions on how to troubleshoot this?

  • IIS7 binding to subdomain causing authentication errors (TFS 2010)

    - by Tommy Jakobsen
    I'm trying to bind a IIS web site (Team Foundation Services 2010) to a subdomain, which is causing authentication errors. First I'll explain what I've done to set it up. This is the fist time I do this, so please correct me if I'm wrong. The web server is a stand-alone Windows Server 2008 R2 x64, running IIS7 with .NET Framework 4. I have the following A-records, pointing to my server: server.mydomain.com *.server.mydomain.com So all subdomains of server.mydomain.com points to the server. In IIS7 I have a web site (TFS 2010) on port 8080, with a virtual directory (named tfs) that is using Windows Authentication. I have one binding on the web site pointing to all unassigned IP addresses, port 8080 and having a host name of tfs.server.mydomain.com. Now, shouldn't I be able to access the virtual directory through: http://tfs.server.mydomain.com/tfs That is not working. However, I can access it through: http://tfs.server.mydomain.com:8080/tfs But, it won't let me authenticate using a Windows account (Server\Username). A windows account that I can authenticate with, when accessing the site through http://localhost:8080/tfs. What am I missing here?

  • Create account for service

    - by Andy
    I am configuring a new server. The server is running Hudson that is going to copy some files from this server to another. The other server is a virtual machine. Both running Windows Server 2012. Hudson is started on server A with log on as "Local System". When I come to the copy phase it says "Access denied". Changing the log on to "Administrator" works. However, I guess this is bad. I do not have much experience with user management. I tried to create a own hudson account on both servers A and B. I tried to log on as hudson account in the service-management but it doesn't start. How would you create an account for this particular service that has access to the shared folder on server B and can be used to start the service on server A? I guess I need two accounts with same username and password on server A and server B? The folder on Server B is shared with everyone and the guest account is enabled.

  • Are there any other causes of this error that are NOT related to initial setup?

    - by LordScree
    I'm trying to diagnose an issue at a customer site. They are receiving the following error: A network-related or instance-specific error occurred while establishing a connection to SQL Server I've seen this a few times, but only during the initial setup - it's often caused by one of the following: The database server is turned off The network connection between the database server and the application is closed or somehow blocked (e.g. a firewall) The SQL Server instance is not set up to receive remote connections from the application server (e.g. TCP is turned off, remote connections are disabled, or the "SQL Server Browser" service is stopped/disabled) However, if I assume that no configuration changes have been made, I'm trying to postulate on what the reason might be for getting this error at a random point after the initial setup. My initial thought is: SQL Server machine has run out of resources (e.g. RAM) and is unable to accept new requests from the application server Is this a valid theory? What other possible causes are there of this error that are not related to the initial setup of the server / application connection? Or is it simply impossible that this error could occur without a configuration change having been made (either on the SQL Server side, application side, or somewhere in-between (network))? NOTE: I believe this question differs from the plethora of questions related to this error message because the application and server have been talking to each other quite happily until now (most, if not all, other questions seem to relate to initial setup).

  • MSSQL 2008 login failed for windows authentication

    - by Force Flow
    I'm running Microsoft SQL 2008 on a Windows 2008 Server. The MSSQL server server authentication is set to SQL Server and Windows Authentication mode. I have created an active directory security group "xyz app users". I have added a normal user (without any active directory admin privledges) and a user with domain admin privledges to the "xyz app users" group. I have added the group to the MSSQL management console as a login user. This group is a member of the public server role and is mapped to two databases. On a workstation, when the normal user is logged in, I configure a DSN ODBC connection, and I'm able to successfully create the DSN and test the SQL connection. However, when I'm logged in as the user with domain admin privledges, when I attempt to configure the DSN ODBC connection, I can't get past the login ID configuration screen. If I select "windows authentication" and click "next", I get an error: Connection failed: SQLState: '28000' SQL Server Error: 18456 [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'mydomain\myuser' On the server's application event logs, this error appears: Login failed for user 'mydomain\myuser'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: 172.x.x.x] And in MSSQL's event logs: Error: 18456, Severity: 14, State: 11 Solutions that I've seen so far do not seem to fit this situation (some solutions I've seen are only applicable when the BUILDIN\Administrator is being used locally on the server, which is not the case here).

    - by GrZeCh
    Hello, I'm having problems with my SQL Server 2008 installation (10.0.2531.0 - SP1 installed). It works as a database server for small hosting environment (about 500 sites). I'm getting errors like this: The client was unable to reuse a session with SPID 62, which had been reset for connection pooling. The failure ID is 29. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message. in Windows event log and when I run this: SELECT * FROM sys.dm_os_performance_counters WHERE object_name = 'SQLServer:General Statistics' I see that one of counters looks a little odd: Logins/sec 429 Connection Reset/sec 163459 Logouts/sec 399 User Connections 30 Logical Connections 33 any ideas how to check what is causing this problem?

  • Server.CreateObject Fails when calling .Net object from ASP on 64-bit windows in IIS 32-bit mode

    I have a server running Windows 2003 64-bit, that runs IIS in 32-bit mode. I have a COM object that was registered using the following command: C:\WINDOWS\microsoft.net\Framework\v2.0.50727>regasm D:\Path\To\MyDll.dll /tlb:MyTLB.tlb /codebase When I create the object via ASP I get: Server object error 'ASP 0177 : 8000ffff' Server.CreateObject Failed /includes/a_URLFilter.asp, line 19 8000ffff When I create the object in a vbs script and use the 32-bit version of cscript (in \Windows\syswow64) it works fine.

  • I need advices: small memory footprint linux mail server with spam filtering

    - by petermolnar
    I have a VPS which is originally destined to be a webserver but some minimal mail capabilities are needed to be deployed as well, including sending and receiving as standalone server. The current setup is the following: Postfix reveices the mail, the users are in virtual tables, stored in MySQL on connection all servers are tested with policyd-weight service against some DNSBLs all mail is runs through SpamAssassin spamd with the help of spamc client the mail is then delivered with Dovecot 2' LDA (local delivery agent), virtual users as well As you saw... there's no virus scanner running, and that's for a reason: clamav eats all the memory possible and also, virus mails are all filtered out with this setup (I've tested the same with ClamAV enabled for 1,5 years, no virus mail ever got even to ClamAV) I don't use amavisd and I really don't want to. You only need that monster if you have plenty of memory and lots of simultaneous scanners. It's also a nightmare to fine tune by hand. I run policyd-weight instead of policyd and native DNSBLs in postfix. I don't like to send someone away because a single service listed them. Important statement: everything works fine. I receive very small amount of spam, nearly never get a false positive and most of the bad mail is stopped by policyd-weight. The only "problem" that I feel the services at total uses a bit much memory alltogether. I've already cut the modules of spamassassin (see below), but I'd really like to hear some advices how to cut the memory footprint as low as possible, mostly: what plugins SpamAssassin really needs and what are more or less useless, regarding to my current postfix & policyd-weight setup? SpamAssassin rules are also compiled with sa-compile (sa-update runs once a week from cron, compile runs right after that) These are some of the current configurations that may matter, please tell me if you need anything more. postfix/master.cf (parts only) dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/bin/spamc -e /usr/lib/dovecot/deliver -d ${recipient} -f {sender} postfix/main.cf (parts only) smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname, permit smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_invalid_hostname, reject_non_fqdn_hostname, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_pipelining, reject_unauth_destination, check_policy_service inet:127.0.0.1:12525, permit policyd-weight.conf (parts only) $REJECTMSG = "550 Mail appeared to be SPAM or forged.

  • How to backup/restore excluding filestream varbinary in SQL Server 2008?

    - by fdierre
    There is an application used in a production site that uses SQL Server 2008 as its DBMS. The database schema uses Filestream Varbinary to save binary data on the filesystem instead of directly into the DB tables. The point is that now and then it would be useful to copy the production database on development machines, mostly for doing troubleshooting. The database is too big for comfortably moving it around, but it would be ok if it could be moved leaving out the filestream varbinary fields. In other words, I am trying to make an "imperfect" copy of a database: i.e., on the destination database, it is ok to have NULL values instead of the varbinary. Is this possible? I tried looking for the feature on the SQL Server Management studio and did a backup that excludes the filegroup containing the filestream varbinary, but I cannot restore: MSSMS complains that the restore cannot be done because the backup is incomplete (of course). Is it possible to achieve what I am trying to do in some way?

  • How can I tell what user account is being used by a service to access a network share on a Windows 2008 server?

    - by Mike B
    I've got a third-party app/service running on a Windows 2003 SP2 server that is trying to fetch something from a network share on Windows 2008 box. Both boxes are members of an AD domain. For some reason, the app is complaining about having insufficient permissions to read/write to the store. The app itself doesn't have any special options for acting on the authority of another user account. It just asks for a UNC path. The service is running with a "log on as" setting of Local System account. I'd like to confirm what account it's using when trying to communicate with the network share. Conversely, I'd also like more details on if/why it's being rejected by the Windows 2008 network share. Are there server-side logs on 2008 that could tell me exactly why a connection attempt to a share was rejected?

    We're using Newrelic to measure our Python/Django application performance. Newrelic is reporting that across our system "Memcached" is taking an average of 12ms to respond to commands. Drilling down into the top dozen or so web views (by # of requests) I can see that some Memcache get take up to 30ms; I can't find a single use of Memcache get that returns in less than 10ms. More details on the system architecture: Currently we have four application servers each of which has a memcached member. All four memcached members participate in a memcache cluster. We're running on a cloud hosting provider and all traffic is running across the "internal" network (via "internal" IPs) When I ping from one application server to another the responses are in ~0.5ms Isn't 10ms a slow response time for Memcached? As far as I understand if you think "Memcache is too slow" then "you're doing it wrong". So am I doing it wrong? Here's the output of the memcache-top command: memcache-top v0.7 (default port: 11211, color: on, refresh: 3 seconds) INSTANCE USAGE HIT % CONN TIME EVICT/s GETS/s SETS/s READ/s WRITE/s cache1:11211 37.1% 62.7% 10 5.3ms 0.0 73 9 3958 84.6K cache2:11211 42.4% 60.8% 11 4.4ms 0.0 46 12 3848 62.2K cache3:11211 37.5% 66.5% 12 4.2ms 0.0 75 17 6056 170.4K AVERAGE: 39.0% 63.3% 11 4.6ms 0.0 64 13 4620 105.7K TOTAL: 0.1GB/ 0.4GB 33 13.9ms 0.0 193 38 13.5K 317.2K (ctrl-c to quit.) ** Here is the output of the top command on one machine: ** (Roughly the same on all cluster machines.

  • Unable to start rabbitmq-server on Ubuntu 12.04

    - by lxyu
    I try to install rabbitmq-server on ubuntu-server 12.04 but failed. Then I add the apt source list following the guide in http://www.rabbitmq.com/install-debian.html But reinstall still have the same error as following: $ sudo aptitude install rabbitmq-server ...

One solution on the internet is to make sure hostname pingable, but my /etc/hosts already have this line on top: 127.0.0.1 localhost myserver Any suggestion on how to get up rabbitmq-server?

  • How should I remotely manage Dell Poweredge 2850 running Ubuntu server?

    - by Saul
    First I've got to say I'm a Linux / Ubuntu novice, so go gentle on me as I'm on day 3. I've managed to get Ubuntu server Ubuntu 8.04 LTS installed and running on the Poweredge 1850 I bought off ebay. The box will go in a rack at my office but I want to be able to work on it and power on and off from home and I gather that (maybe) IPMI over LAN might be the way to do this, or maybe its something to do with BMC or something? I want to be able to administer/manage from a client PC at home running XP. I will be configuring the office router to port forward port 80 and 443 to the Ubuntu server running Apache2, and I'm puzzled about how the remote management works (unless it comes on a different port forwarded to a different internal IP) Thanks for any help

  • How can I get rid of / hide :2eDS_Store files on my linux netatalk server?

    - by Douglas Mayle
    I'm running a netatalk server process on my linux server that serves files up to Mac client machines. Whenever you use Mac's Finder to access foreign filesystems over netatalk, it creates '.DS_Store' files to store information about the folder. Normally, these files would be hidden by default, and I wouldn't care. Unfortunately, netatalk doesn't allow access to local hidden files, so when the Mac writes and reads these, it renames them :2eDS_Store on the local filesystem. When you have a deep tree, you end up with these littered all over the place, and other Windows and Linux clients have to deal with them. How do I make these available to Mac clients and hidden from everyone else?

  • Windows: Running an AutoIt script to launch a GUI app - on a server, when no one is logged in

    - by mrled
    I want to run an AutoIt script every day at 1:00 AM on a Windows 2003 Server Standard Edition. Since this is a server, obviously there is rarely someone sitting there logged in at the console, so the procedure needs to account for this. The AutoIt script in question launches and sends keypresses to a GUI app, so the process needs to include creating some sort of session for the user running the schedule task. Is there a way to do this? I can't just use scheduled tasks run the AutoIt script when no one is logged in - if I do, it fails to launch at all. I thought that I might be able to create an RDP session and run the scheduled task as that user, inside that session, but I haven't found a way to create an RDP session without launching mstsc.exe -- which is itself a GUI app, and I have the same problem again.
