  • directive is not allowed here Nginx Passenger

    - by ThinkBohemian
    I'm trying to enable Global Queuing in passenger and i'm using Nginx. When i set the flag passenger_use_global_queue I get an error [emerg]: "passenger_use_global_queue" directive is not allowed here in nginx.conf:22". Does anyone know the propper place to put passenger_use_global_queue, or to get rid of the error message? Below is a snippit of my nginx.conf with the offending line: #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { passenger_root /opt/ruby-enterprise-1.8.7-20090928/lib/ruby/gems/1.8/gems/passenger-2.2.5; passenger_ruby /opt/ruby-enterprise-1.8.7-20090928/bin/ruby; passenger_use_global_queue on

  • Hyper-V Deployment Options Best Practices

    - by Erv Walter
    In what circumstances would you choose each of the following deployment options: Hyper-V installed as the bare bones Windows Hyper-V Server 2008 R2 Hyper-V role installed on a Windows Server 2008 R2 Server Core installation Hyper-V role installed on a Windows Server 2008 R2 Full Installation For example, I know there are licensing considerations for each option: With Hyper-V on top of a full installation of Enterprise or Data Center edition, you can use Windows Server as a guest OS without needing additional licenses (4 for Enterprise, unlimited for Data Center) With "Windows Hyper-V Server" you have to obtain licenses for each guest OS. But my real question is, are there technical considerations as well? I understand that the Full Installation doesn't perform as well as the other two options, but is there a significant difference between Server Core and "Windows Hyper-V Server"? What are the pros and cons of Hyper-V on Server Core vs "Windows Hyper-V Server" and when would you choose each?

  • EJB3 - using 2 persistence units within a transaction (Exception: Local transaction already has 1 no

    - by Sorcha
    I am trying to use 2 persistence units within the same transaction in a JEE application deployed on Glassfish. The 2 persistence units are defined in persistence.xml, as follows: <persistence-unit name="BeachWater"> <jta-data-source>jdbc/BeachWater</jta-data-source> ... <persistence-unit name="LIMS"> <jta-data-source>jdbc/BeachWaterLIMS</jta-data-source> ... These persistence units correspond to JDBC resources and connection pools which I had defined in Glassfish as follows (include one here as both are identical apart from names & database connection info): JDBC Resource: JNDI Name: jdbc/BeachWaterLIMS Pool Name: BEACHWATER_LIMS Connection Pool: Name: BEACHWATER_LIMS Datasource Classname: com.microsoft.sqlserver.jdbc.SQLServerConnectionPoolDataSource Resource Type: javax.sql.ConnectionPoolDataSource There are 3 stateless session beans, LimsServiceBean, AnalysisServiceBean and AnalysisDataTransformationServiceBean. Here are the relevant snippets from LimsServiceBean: @PersistenceContext(unitName = "LIMS") EntityManager em; ... public ArrayList<Sample> getLatestLIMSData() { Query q = em.createNamedQuery("Sample.findBySubTypeStatus"); return new ArrayList<Sample>(q.getResultList()); } From AnalysisServiceBean: @PersistenceContext(unitName = "BeachWater") EntityManager em; ... public ArrayList<AnalysisType> getAllAnalysisTypes() { Query q = em.createNamedQuery("AnalysisType.findAll"); return new ArrayList<AnalysisType>(q.getResultList()); } And from AnalysisDataTransformationServiceBean: @EJB private AnalysisService analysisService; @EJB private LimsService limsService; public void transformData() { List<AnalysisType> analysisTypes = analysisService.getAllAnalysisTypes(); ArrayList<Sample> samples = limsService.getLatestLIMSData(); This call to limsService.getLatestLIMSData() caused the following exception: [exec] Caused by: javax.ejb.TransactionRolledbackLocalException: Exception thrown from bean; nested exception is: Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.1 (Build b60e-fcs (12/23/2008))): oracle.toplink.essentials.exceptions.DatabaseException [exec] Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: java.lang.IllegalStateException: Local transaction already has 1 non-XA Resource: cannot add more resources. Having consulted this page, http://msdn.microsoft.com/en-us/library/ms378484.aspx (among many others), I tried changing the definition of the connection pools to: Connection Pool: Name: BEACHWATER_LIMS Datasource Classname: com.microsoft.sqlserver.jdbc.SQLServerXADataSource Resource Type: javax.sql.XADataSource Ping via the Glassfish admin console succeeds, but call to analysisService.getAllAnalysisTypes() now throws an exception: Caused by: javax.ejb.TransactionRolledbackLocalException: Exception thrown from bean; nested exception is: Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.1 (Build b60e-fcs (12/23/2008))): oracle.toplink.essentials.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Error in allocating a connection.

  • How to sysprep SQL Server Express?

    - by Jim
    We plan to deploy Hyper-V VHD with Windows Server 2008 R2 and SQL Server 2012 Express installed to multiple hosts. From my understanding, the correct way to do this is to install SQL Server in prepartion mode, sysprep Windows, then complete SQL Server installation when the VHD is deployed. I mostly followed the process in this blog post: http://sethusrinivasan.com/category/sysprep/ However, after the VHD is deployed, I'm unable to complete the SQL Server installation. It keeps saying "Upgrade matrix is incorrect". It seems that it's trying to upgrade itself to Enterprise edition (I was asked for product key during install, but I skipped it). Could anyone share their experience in deploying VHDs with SQL Server (we're fine with either SQL Server 2008 R2 or 2012)? I think the source of my issue is because I can't select "Express Edition" when entering the product key at the completion stage, so the installation is trying to do an upgrade to Enterprise Edition. I have no idea why the drop down list is empty.

  • API Management Solutions

    - by Mike
    I'm currently building an API and am looking for a tool to allow me to monitor (in a GUI) and rate limit usage. I've come across a few enterprise solutions including: http://apigee.com/ http://mashery.com/ http://www.layer7tech.com/ http://www.3scale.net/ The Apigee enterprise plan is exactly what I'm looking for but plans start at $3000 / month which is out of my price range. The other solutions are all either to expense or do not provide the solution I'm looking for. This led me to look at some open source options including: http://apiaxle.com/ https://code.google.com/p/varnish-apikey/wiki/UsageManual Varnish seems like a fairly complete solution, however I would need to build a GUI to visualise the data. My final option would to build a solution from scratch using EventMachine and ruby. Any advice?

  • Mono Project: How to install Mono framework on Red Hat Linux which is compiled on centOS ?

    - by funwithcoding
    We have Red Hat Enterprise Linux servers at work place. However we dont have Red Hat Linux desktops. So I used CentOS 5.4 to compile the Mono sources and generated the Mono framework for CentOS and tested with some sample codes and I am satisfied. I want to transfer this compiled framework to Red Hat Enterprise Linux 5. How Can I do that? Do I have to compile the Mono framework statically or do I have to copy the linked libraries as well? I am not familiar with linux much. Any help is highly appreciated.

  • Old operational master still thinks it is the "one"

    - by Doug
    Hi there, I have a domain with 3 AD servers for now i'll just call them: AD01 (Win 2008 GC, Operations master) AD02 (Win 2008 GC) AD03 (Win 2003 GC) A couple of months there was some hardware issues with AD01 so the operations master, PDC and Infrastructure Master was moved to AD02. All machines where on while this was happening. AD01 (Win 2008 GC) AD02 (Win 2008 GC, Operations master) AD03 (Win 2003 GC) AD01 was then shutdown for a month. Upon starting this machine up with replaced hardware (NIC and RAID card) i now have a weird problem. AD01 Thinks it is operations master still in AD on the local box AD02 & AD03 Thinks AD02 is operations master in AD on both boxes When running DCDIAG on AD01 i get a number of issues (listed below) When running "dcdiag /test:advertising" on AD01: Doing primary tests Testing server: Default-First-Site-Name\AD01 Starting test: Advertising Warning: DsGetDcName returned information for \\ad02.domain.local, when we were trying to reach AD01. SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE. ......................... AD01 failed test Advertising Running partition tests on : ForestDnsZones Running partition tests on : DomainDnsZones Running partition tests on : Schema Running partition tests on : Configuration Running partition tests on : domain Running enterprise tests on : domain.local When running "dcdiag" on AD01 i get the following errors (excerpt of the Final output): Testing server: Default-First-Site-Name\AD01 Starting test: Advertising Warning: DsGetDcName returned information for \\ad02.domain.local, when we were trying to reach AD01. SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE. ......................... AD01 failed test Advertising Starting test: FrsEvent There are warning or error events within the last 24 hours after the SYSVOL has been shared. Failing SYSVOL replication problems may cause Group Policy problems. Starting test: NCSecDesc Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have Replicating Directory Changes In Filtered Set access rights for the naming context: DC=ForestDnsZones,DC=domain,DC=local Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have Replicating Directory Changes In Filtered Set access rights for the naming context: DC=DomainDnsZones,DC=domain,DC=local Starting test: Replications [Replications Check,Replications Check] Inbound replication is disabled. To correct, run "repadmin /options AD01 -DISABLE_INBOUND_REPL" [Replications Check,AD01] Outbound replication is disabled. To correct, run "repadmin /options AD01 -DISABLE_OUTBOUND_REPL" So the problem appeasr to be that when i moved the operations master, AD01 never got the memo, and now that it's started up, all the other AD servers don't think its the boss anymore when it trys to replicate etc. So i really need to manually update AD01 so that it knows who the operations master, instrastructure and PDC is - but i'm not having any luck I've been googling for nearly a day and all solutions lead to "the cake is a lie" Your ninja skills will be greatly appreciated

  • Windows Home Server style redundancy/multi-disk-support on Windows Server 2008 R2?

    - by user19597
    I'm setting up a fileserver for our department. It'll be connected to the domain. I want it to have a very large amount of storage (several TB). Ideally, it should also preserve disk space by identifying identical files and only storing them once. It should be fault tollerant so that if one of the drives fails, that drive can be replaced without losing any data. All of these features are available in Microsoft's consumer offering - Windows Home Server. However, I can't find these kind of features within the enterprise Windows Server 2008 R2. Am I missing something? I know that I could buy a Drobo, or similar, and use this instead. However, I would prefer to use a built-in feature of Windows Server should it exist. It seems surprising to me that these features should be available in Home Server but not in an enterprise fileserver.

  • ant compile problem

    - by senzacionale
    If I start ant compile in JDeveloper all classes are compiled successfully and copied to the classes folder. But if I run ant compile from console then no classes are copied to the classes folder. Does anyone know why? Maybe the problem is with: build.compiler=oracle.ojc.ant.taskdefs.OjcAdapter? build.properties: javac.debug=on oracle.home=C:/Oracle/jdevstudio10133 build.compiler=oracle.ojc.ant.taskdefs.OjcAdapter output.dir=classes javac.deprecation=on javac.nowarn=off package.name=KIS dest.dir=C:/Projekti/Projekt ANT/CVS src.dir=src view.dir=View model.dir=Model modelirc2000.dir=ModelIRC2000 build.xml for compile <target name="compile" description="Compile Java source files" depends="init"> <javac destdir="${dest.dir}/${package.name}/${model.dir}/${output.dir}" classpathref="classpath" debug="${javac.debug}" nowarn="${javac.nowarn}" deprecation="${javac.deprecation}" encoding="Cp1250" source="1.5" target="1.5"> <src path="${dest.dir}/${package.name}/${model.dir}/${src.dir}"/> <exclude name="irc/kis/model/dm/entity/common/ZnanjeImplMsgBundle.java/"/> <exclude name="META-INF/"/> <exclude name="irc/kis/view/"/> <exclude name="irc/kis/model/zap/view/vp/"/> </javac> </target> <target name="copy" description="Copy files to output directory" depends="init"> <patternset id="copy.patterns"> <include name="**/*.gif"/> <include name="**/*.jpg"/> <include name="**/*.jpeg"/> <include name="**/*.png"/> <include name="**/*.properties"/> <include name="**/*.xml"/> <include name="**/*-apf.xml"/> <include name="**/*.ejx"/> <include name="**/*.xcfg"/> <include name="**/*.cpx"/> <include name="**/*.dcx"/> <include name="**/*.wsdl"/> <include name="**/*.ini"/> <include name="**/*.tld"/> <include name="**/*.tag"/> <include name="**/*.jpx"/> </patternset> <copy todir="${dest.dir}/${package.name}/${model.dir}/${output.dir}"> <fileset dir="${dest.dir}/${package.name}/${model.dir}/${src.dir}"> <patternset refid="copy.patterns"/> </fileset> </copy> </target>

  • Why is business-class storage so expensive?

    - by Mark Henderson
    This is a Canonical Question about the Cost of Enterprise Storage. See also the following question: What's the best way to explain storage issues to developers and other users Regarding general questions like: Why do I have to pay 50 bucks a month per extra gigabyte of storage? Our file server is always running out of space, why doesn't our sysadmin just throw an extra 1TB drive in there? Why is SAN equipment so expensive? The Answers here will attempt to provide a better understanding of how enterprise-level storage works and what influences the price. If you can expand on the Question or provide insight as to the Answer, please post.

  • Sql 2008 r2 DEV install failed

    - by obulay
    I am trying to install Sql 2008 r2 DEVeloper on Windows 2008 STD. It previously had Sql 2008 Enterprise installed. I first uninstalled SQL 2008. I think uninstall still leaves some crap in registery, and in Program files. Installation fails in the last step of the process - installation, about couple of minutes into it. Can't insert picture for you because serverfault does not allow me to do so. But it basically it: Error message: "Installation failed" I re-installed SQL 2008 Enterprise on this box and we are not going to go to R2 on older servers that previously had SQL 2005 or SQL 2008 on it. Looking at Windows log: Activation context generation failed for "C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\x64\Microsoft.SqlServer.Configuration.SqlServer_ConfigExtension.dll".

  • Cancel table design change in SQL Server 2000

    - by Bryce Wagner
    In SQL Server Enterprise Manager and change one of the columns and save it, it will create a table with the new definition, and copy all the data to that new table, and then delete the old table when it's done. But if your table is large (let's say on the order of 100GB), it can take a long time to do this. Even worse, if you don't have sufficient disk space, it doesn't notice ahead of time, and it will spend a long time trying to copy the table, run out of space, and then decide to abort the process. We have other ways to copy the data in smaller chunks, but those require significantly more manual intervention, so it's usually easier to just let Enterprise Manager figure it out, as long as there's enough disk space. So for a long running "Design Table" save like this, is there any way to cancel once it's started? Or do you just have to wait for it to fail?

  • How fast is Berkeley DB SQL compared to SQLite?

    - by dan04
    Oracle recently released a Berkeley DB back-end to SQLite. I happen to have a hundreds-of-megabytes SQLite database that could very well benefit from "improved performance, concurrency, scalability, and reliability", but Oracle's site appears to lack any measurements of the improvements. Has anyone here done some benchmarking?

    Hi, I have successfully configured Windows Server 2008 Enterprise SP2 with SQL Server 2008 Enterprise SP2 all 64 bit, however when I tried to access this particular SQL Server 2008 DB instance from another SQL Server 2008 SSMS in another Windows Server 2008 it failed ? what I did is to disabled the IPv6 IP address using the regedit but still the problem hasn't been fixed even after restart ? I have enabled the named piped as well but still no luck ? any help please ? Here's the error message: " A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

  • Installing Java on a Virtual Private Server

    - by Martin Rowe
    I have recently managed to get my employer to pay for a vps. I teach and asked the vps provider to enable Perl, Python, Ruby, Tomcat and Java. They've done the first four (really quickly) but have got back to me asking which parts of Java I need. I think the Java Virtual Machine is a given but what other S/W do I need to get installed? I think by getting the vps I now have the chance to teach Enterprise Java and want to get into Java Message Server and Enterprise patterns. Can I get Glassfish installed or is that a silly question? What about servlets and beans? Thanks in anticipation Martin Rowe

  • Are there any statistics on the number of networks using Ethernet Jumbo frames?

    - by Russell Heilling
    I am often told by Sales Engineers and Product managers that a Layer 2 Ethernet service is not fit for purpose if the maximum supported frame size is in the 1518-1522 range (enough to support standard Ethernet frames or VLAN tagged frames). Or in other words: an MTU of 1500 is not enough (see this blog post for my definition of MTU and a short rant on how the term is often misused) I am never able to get any details from them on: a) What proportion of customers (Enterprise / SMB) require Jumbo frames b) What are typical expectations on frame size for Jumbos on WAN links? 1600, 2000, 9k, etc... I know that in Telco and Data Centre environments Jumbos are pretty common, but I am after some insight as to how common this is within Enterprise and SMB networks.

  • How do you find the disk size of a Postgres table and its indexes

    - by mmrobins
    I'm coming to Postgres from Oracle and looking for a way to find the table and index size in terms of bytes/MB/GB/etc, or even better the size for all tables. In Oracle I had a nasty long query that looked at user_lobs and user_segments to give back an answer. I assume in Postgres there's something I can use in the information_schema tables, but I'm not seeing where. Thanks in advance.

  • Is Sql Server 2008 R2 unsupported by Operations Manager (SCOM) 2007 R2?

    - by bwerks
    Hey all, I'm performing a test configuration of System Center Operations Manager 2007 R2, on a system prepared with Sql Server 2008 R2. Unfortunately, the Scom 2007 R2 prerequisites verification program seems to be detecting exact versions of Sql Server, and not simply a minimum version, like it claims: "System Center Operations Manager 2007 R2 requires SQL Server 2005 Standard or Enterprise Edition with SP1 and above or SQL Server 2008 Standard or Enterprise edition with SP1 and above. Note: Operations Manager 2007 R2 does not support a 32-bit Operations Manager Operations database, Reporting Server data warehouse or Audit Collection database on a 64-bit operating system." I had hoped that this was just a helper tool that was assisting in getting me off the ground, but unfortunately it seems as if it's actually used as a gate for the installation to proceed. Has anyone encountered this? If so, is there a way to fool the installer into thinking that it has a proper version, or otherwise alert it to my valid configuration?
