Need data on disk drive management by OS: getting base I/O unit size, “sync” option, Direct Memory A

- by Richard T

Hello All, I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: the database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it. When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it. I have been looking for information on how to ensure these are so for CENTOS and Ubuntu, but can't seem to find anything at all! I want to be able to check these things and change them if needed. Any and all input appreciated.

C# Proposal: Compile Time Static Checking Of Dynamic Objects

- by Paulo Morgado

C# 4.0 introduces a new type: dynamic. dynamic is a static type that bypasses static type checking. This new type comes in very handy to work with: The new languages from the dynamic language runtime. HTML Document Object Model (DOM). COM objects. Duck typing … Because static type checking is bypassed, this: dynamic dynamicValue = GetValue(); dynamicValue.Method(); is equivalent to this: object objectValue = GetValue(); objectValue .GetType() .InvokeMember( "Method", BindingFlags.InvokeMethod, null, objectValue, null); Apart from caching the call site behind the scenes and some dynamic resolution, dynamic only looks better. Any typing error will only be caught at run time. In fact, if I’m writing the code, I know the contract of what I’m calling. Wouldn’t it be nice to have the compiler do some static type checking on the interactions with these dynamic objects? Imagine that the dynamic object that I’m retrieving from the GetValue method, besides the parameterless method Method also has a string read-only Property property. This means that, from the point of view of the code I’m writing, the contract that the dynamic object returned by GetValue implements is: string Property { get; } void Method(); Since it’s a well defined contract, I could write an interface to represent it: interface IValue { string Property { get; } void Method(); } If dynamic allowed to specify the contract in the form of dynamic(contract), I could write this: dynamic(IValue) dynamicValue = GetValue(); dynamicValue.Method(); This doesn’t mean that the value returned by GetValue has to implement the IValue interface. It just enables the compiler to verify that dynamicValue.Method() is a valid use of dynamicValue and dynamicValue.OtherMethod() isn’t. If the IValue interface already existed for any other reason, this would be fine. But having a type added to an assembly just for compile time usage doesn’t seem right. So, dynamic could be another type construct. Something like this: dynamic DValue { string Property { get; } void Method(); } The code could now be written like this; DValue dynamicValue = GetValue(); dynamicValue.Method(); The compiler would never generate any IL or metadata for this new type construct. It would only thee used for compile type static checking of dynamic objects. As a consequence, it makes no sense to have public accessibility, so it would not be allowed. Once again, if the IValue interface (or any other type definition) already exists, it can be used in the dynamic type definition: dynamic DValue : IValue, IEnumerable, SomeClass { string Property { get; } void Method(); } Another added benefit would be IntelliSense. I’ve been getting mixed reactions to this proposal. What do you think? Would this be useful?

Though I restart the jboss server again, it does not invoke. I need to restart the server machine itself. Can anyone please let me know what could be the cause of these problems and the workable resolutions or any suggestion ? Kindly dont degrade the question as I am facing a lot problems due to this hanging issue. Also for the information, the application is based on Java, GWT, Hibernate 3.

C# .NET MVC Call an action from another controller

- by Brian

I have two different objects: contracts, and task orders. My requirements specify that in order to view the Details for either object, the Url should be "http://.../Contract/Details" or "http://.../TaskOrder/Details" depending on which type. They are both very similar and the details pages are almost identical, so I made a class that can either be a contract or a task order, and has a variable "objectTypeID" that says which type it is. I wrote the action "Details" in the task order controller, but now I want to call that from the contract controller instead of recopying the code. So is there any way to have the url still say ".../Contract/Details" but call the action in the TaskOrder controller instead? I tried using TaskOrderController TOController = new TaskOrderController(); TOController.Details(id); This would have worked except that I can't use the HttpContext.Session anymore, which I used several times in the action.

Why won't jqGrid won't populate initially in Chrome

Hi, I've got a web page with a jqGrid that uses am xmlreader to populate itself with data that is spat out by a RoR service. The page loads fine in firefox and safari.

Except netNamedPipeBinding, we can have multiple endpoints of same transport.Is it correct? example <service name = "TestService"> <endpoint address = "http://localhost:8000/TestService/" binding = "wsHttpBinding" contract = "ITestContract" /> <endpoint address = "net.tcp://localhost:8001/TestService/" binding = "netTcpBinding" contract = "ITestContract" /> <endpoint address = "net.tcp://localhost:8002/TestService/" binding = "netTcpBinding" contract = "IMyOtherTestContract"/> </service>

nhibernate/fluenthibernate throws StackOverflowException

- by Gianluca Colucci

Hi there! In my project I am using NHibernate/FluentNHibernate, and I am working with two entities, contracts and services. This is my contract type: [Serializable] public partial class TTLCContract { public virtual long? Id { get; set; } // other properties here public virtual Iesi.Collections.Generic.ISet<TTLCService> Services { get; set; } // implementation of Equals // and GetHashCode here } and this is my service type: [Serializable] public partial class TTLCService { public virtual long? Id { get; set; } // other properties here public virtual Activity.Models.TTLCContract Contract { get; set; } // implementation of Equals // and GetHashCode here } Ok, so as you can see, I want my contract object to have many services, and each Service needs to have a reference to the parent Contract. I am using FluentNhibernate. So my mappings file are the following: public TTLCContractMapping() { Table("tab_tlc_contracts"); Id(x => x.Id, "tlc_contract_id"); HasMany(x => x.Services) .Inverse() .Cascade.All() .KeyColumn("tlc_contract_id") .AsSet(); } and public TTLCServiceMapping() { Table("tab_tlc_services"); Id(x => x.Id, "tlc_service_id"); References(x => x.Contract) .Not.Nullable() .Column("tlc_contract_id"); } and here comes my problem: if I retrieve the list of all contracts in the db, it works. if I retrieve the list of all services in a given contract, I get a StackOverflowException.... Do you see anything wrong with what I wrote? Have I made any mistake? Please let me know if you need any additional information. Oh yes, I missed to say... looking at the stacktrace I see the system is loading all the services and then it is loading again the contracts related to those services. I don't really have the necessary experience nor ideas anymore to understand what's going on.. so any help would be really really great! Thanks in advance, Cheers, Gianluca.

database schema eligible for delta synchronization

- by WilliamLou

it's a question for discussion only. Right now, I need to re-design a mysql database table. Basically, this table contains all the contract records I synchronized from another database. The contract record can be modified, deleted or users can add new contract records via GUI interface. At this stage, the table structure is exactly the same as the Contract info (column: serial number, expiry date etc.). In that case, I can only synchronize the whole table (delete all old records, replace with new ones). If I want to delta(only synchronize with modified, new, deleted records) synchronize the table, how should I change the database schema? here is the method I come up with, but I need your suggestions because I think it's a common scenario in database applications. 1)introduce a sequence number concept/column: for each sequence, mark the new added records, modified records, deleted records with this sequence number. By recording the last synchronized sequence number, only pass those records with higher sequence number; 2) because deleted contracts can be added back, and the original table has primary key constraints, should I create another table for those deleted records? or add a flag column to indicate if this contract has been deleted? I hope I explain my question clearly. Anyway, if you know any articles or your own suggestions about this, please let me know. Thanks!

Could not find default endpoint element

- by edosoft

I've added a proxy to a webservice to a VS2008/.NET 3.5 solution. When constructing the client .NET throws this error: Could not find default endpoint element that references contract 'IMySOAPWebService' in the service model client configuaration section. This might be because no configuaration file was found for your application or because no end point element matching this contract could be found in the client element Searching for this error tells me to use the full namespace in the contract. Here's my app.config with full namespace: <client> <endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService" binding="basicHttpBinding" bindingConfiguration="IMySOAPWebServicebinding" contract="Fusion.DataExchange.Workflows.IMySOAPWebService" name="IMySOAPWebServicePort" /> </client> I'm running XP local (I mention this because a number of Google hits mention win2k3) The app.config is copied to app.exe.config, so that is also not the problem. Any clues?

How to get unique values when using a UNION mysql query

- by Roland

I have 2 sql queries that return results, both contain a contract number, now I want to get the unique values of contract numbers HEre's the query (SELECT contractno, dsignoff FROM campaigns WHERE clientid = 20010490 AND contractno != '' GROUP BY contractno,dsignoff) UNION (SELECT id AS contractno,signoffdate AS dsignoff FROM contract_details WHERE clientid = 20010490) So for example, if the first query before the union returns two results with contract no 10, and the sql query after the union also returns 10, then we have 3 rows in total, however because contractno of all three rows is 10, I need to have only one row returned, Is this possible?

How to join table to itself and select max values in SQL

- by Jakub Konop

I have a contracts table: contractId date price partId 1 20120121 10 1 2 20110130 9 1 3 20130101 15 2 4 20110101 20 2 The contract with greatest date being the active contract (don't blame me, I blame infor for creating xpps) I need to create query to see only active contracts (one contract per part, the contract with highest date). So the result of the query should be like this: contractId date price partId 1 20120121 10 1 3 20130101 15 2 I am out of ideas here, I tried self joining the table, I tried aggregation functions, but I can't figure it out. If anyone would have any idea, please share them with me..

Call an action from another controller

- by Brian

I have two different objects: contracts, and task orders. My requirements specify that in order to view the Details for either object, the Url should be "http://.../Contract/Details" or "http://.../TaskOrder/Details" depending on which type. They are both very similar and the details pages are almost identical, so I made a class that can either be a contract or a task order, and has a variable "objectTypeID" that says which type it is. I wrote the action "Details" in the task order controller, but now I want to call that from the contract controller instead of recopying the code. So is there any way to have the url still say ".../Contract/Details" but call the action in the TaskOrder controller instead? I tried using TaskOrderController TOController = new TaskOrderController(); TOController.Details(id); This would have worked except that I can't use the HttpContext.Session anymore, which I used several times in the action.

How to configure a specific service operation to be accessible through a different End Point

- by pradeeptp

I have single service contract that has 2 service operations. Let me call these operations as X1 and X2. How do I configure X1 to be accessible through HTTP and X2 to be accessible through TCP/IP. If I configure the service contract to be accessibel to TCP/IP end point then both X1 and X2 will be accessible through TCP/IP. Same is the case if I configure the same service contract with HTTP protocol. I could have two different service contracts for achieving what I want, but I want to know if I could achieve the same through a single service contract.

setting default values for empty nodes

- by azathoth

Hello all I need to transform a piece of XML, so that the value of every node in a list I specify is set to "0" for example: <contract> <customerName>foo</customerName> <contractID /> <customerID>912</customerID> <countryCode/> <cityCode>7823</cityCode> </contract> would be transformed into <contract> <customerName>foo</customerName> <contractID>0</contractID> <customerID>912</customerID> <countryCode>0</contractID> <cityCode>7823</cityCode> </contract> How can this be accomplished using XSLT? I have tried some examples I found but none works as expected Thank you

Can I find out what WCF methods are supported on the endpoint before calling it?

- by alord1689

I have a versioning issue with a WCF service contract in which one of the many endpoints which are called for the operation is missing one method from the contract. My question is, how can I make sure the command is available on the client before attempting to call it? I tried: foreach (var od in proxy.Endpoint.Contract.Operations) { if (od.Name == "MyMethodName") { hasMethod = true; break; } } Unfortunately, this is using the contract from the calling app and does not actually describe the implementations on the endpoint itself. As a result, it returns true even though the endpoint has failed to implement the command.

Enabling XML-documentation for code contracts

- by DigiMortal

One nice feature that code contracts offer is updating of code documentation. If you are using source code documenting features of Visual Studio then code contracts may automate some tasks you otherwise have to implement manually. In this posting I will show you some XML documentation files with documented contracts. I will also explain how this feature works. Enabling XML-documentation in project settings As a first thing let’s enable generating of code documentation under project settings. Open project properties, move to Build page and make check to checkbox called “XML documentation file”. Save project settings and rebuild project. When project is built go to bin/Debug folder and open the XML-file. Here is my XML. <?xml version="1.0"?> <doc> <assembly> <name>Eneta.Examples.CodeContracts.Testable</name> </assembly> <members> <member name="T:Eneta.Examples.CodeContracts.Testable.Randomizer"> <summary> Class for generating random integers in user specified range. </summary> </member> <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.#ctor(Eneta.Examples.CodeContracts.Testable.IRandomGenerator)"> <summary> Constructor of Randomizer. Initializes Randomizer class. </summary> <param name="generator">Instance of random number generator.</param> </member> <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.GetRandomFromRangeContracted(System.Int32,System.Int32)"> <summary> Returns random integer in given range. </summary> <param name="min">Minimum value of random integer.</param> <param name="max">Maximum value of random integer.</param> </member> </members> </doc> You can see nothing about code contracts here. Enabling code contracts documentation Code contracts have their own settings and conditions for documentation. Open project properties and move to Code Contracts tab. From “Contract Reference Assembly” dropdown check Build and make check to checkbox “Emit contracts into XML doc file”. And again – save project setting, build the project and move to bin/Debug folder. Now you can see that there are two files for XML-documentation: <assembly name>.XML <assembly name>.old.XML First files is documentation with contracts, second file is original documentation without contracts. Let’s see now what is inside our new XML-documentation file. <?xml version="1.0"?> <doc> <assembly> <name>Eneta.Examples.CodeContracts.Testable</name> </assembly> <members> <member name="T:Eneta.Examples.CodeContracts.Testable.Randomizer"> <summary> Class for generating random integers in user specified range. </summary> </member> <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.#ctor(Eneta.Examples.CodeContracts.Testable.IRandomGenerator)"> <summary> Constructor of Randomizer. Initializes Randomizer class. </summary> <param name="generator">Instance of random number generator.</param> </member> <member name="M:Eneta.Examples.CodeContracts.Testable.Randomizer.GetRandomFromRangeContracted(System.Int32,System.Int32)"> <summary> Returns random integer in given range. </summary> <param name="min">Minimum value of random integer.</param> <param name="max">Maximum value of random integer.</param> <requires description="Min must be less than max" exception="T:System.ArgumentOutOfRangeException"> min < max</requires> <exception cref="T:System.ArgumentOutOfRangeException"> min >= max</exception> <ensures description="Return value is out of range"> Contract.Result<int>() >= min && Contract.Result<int>() <= max</ensures> </member> </members> </doc> As you can see then code contracts are pretty well documented. Messages that I provided with code contracts are also available in documentation. If I wrote very good and informative messages then these messages are very useful also in contracts documentation. Code contracts and Sandcastle Sandcastle knows nothing about code contracts by default. There is separate package of file for Sandcastle that is provided you by code contracts installation. You can read from code contracts manual: “Sandcastle (http://www.codeplex.com/Sandcastle) is a freely available tool that generates help les and web sites describing your APIs, based on the XML doc comments in your source code. The CodeContracts install contains a set of les that can be copied over a Sandcastle installation to take advantage of the additional contract information. The produced documentation adds a contract section to methods with declared requires and/or ensures. In order for Sandcastle to produce Contract sections, you need to patch a number of files in its installation. Please refer to the Sandcastle Readme.txt found under Start Menu/CodeContracts/Sandcastle for instructions. A future release of Sandcastle will hopefully support contract sections without the need for this patching step.” Integrating code contracts documentation to Sandcastle will be one of my next postings about code contracts. Conclusion if you are using code documentation then documentation about code contracts can be added to documentation very easily. All you have to do is to enable XML-documentation for contracts and build your project. Later you can use Sandcastle files provided by code contracts installer to integrate contracts documentation to your output documentation package.

The Oracle Enterprise Linux Software and Hardware Ecosystem

- by sergio.leunissen

It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN). At the same time, Oracle's Linux kernel team is shaping the future of enterprise Linux distributions by developing technologies and features that matter to customers who deploy Linux in the data center, including file systems, memory management, high performance computing, data integrity and virtualization. All this work is contributed to the Linux and Xen communities. The list below is a sample of the partners who have certified their products with Oracle Enterprise Linux. If you're interested in certifying your software or hardware with Oracle Enterprise Linux, please contact us via [email protected] Chip Manufacturers Intel, Intel Enabled Server Acceleration Alliance AMD Server vendors Cisco Unified Computing System Dawning Dell Egenera Fujitsu HP Huawei IBM NEC Sun/Oracle Storage Systems, Volume Management and File Systems 3Par Compellent EMC VPLEX FalconStor Fusion-io Hitachi Data Systems HP Storage Array Systems Lustre Network Appliance OCFS2 PillarData Symantec Veritas Storage Foundation Networking: Switches, Host Bus Adapters (HBAs), Converged Network Adapters (CNAs), InfiniBand Brocade Emulex Mellanox QLogic Voltaire SOA and Middleware ActiveState ActivePerl, ActivePython Tibco Zend Backup, Recovery & Replication Arkeia Network Backup Suite BakBone NetVault CommVault Simpana 8 EMC Networker, Replication Manager FalconStor Continuous Data Protector HP Data Protector NetApp Snapmanager Quest LiteSpeed Engine Steeleye Data Replication, Disaster Recovery Symantec NetBackup, Veritas Volume Replicator, Symantec Backup Exec Zmanda Amanda Enterprise Data Center Automation BMC CA Unicenter HP Server Automation (formerly Opsware), System Management Homepage Oracle Enterprise Manager Ops Center Quest Vizioncore vFoglight Pro TeamQuest Manager Clustering & High Availability FUJITSU x10sure NEC Express Cluster X Steeleye Lifekeeper Symantec Cluster Server Univa UniCluster Virtualization Platforms and Cloud Providers Amazon EC2 Citrix XenServer Rackspace Cloud VirtualBox VMWare ESX Security Management ArcSight: Enterprise Security Manager, Logger CA Access Control Centrify Suite Ecora Auditor FoxT Manager Likewise: Unix Account Management Lumension Endpoint Management and Security Suite QualysGuard Suite Quest Privilege Manager McAfee Application Control, Change ControlIntegrity Monitor, Integrity Control, PCI Pro Solidcore S3 Symantec Enterprise Security Manager (ESM) Tripwire Trusted Computer Solutions

JMX Based Monitoring - Part Three - Web App Server Monitoring

- by Anthony Shorten

In the last blog entry I showed a technique for integrating a JMX console with Oracle WebLogic which is a standard feature of Oracle WebLogic 11g. Customers on other Web Application servers and other versions of Oracle WebLogic can refer to the documentation provided with the server to do a similar thing. In this blog entry I am going to discuss a new feature that is only present in Oracle Utilities Application Framework 4 and above that allows JMX to be used for management and monitoring the Oracle Utilities Web Applications. In this case JMX can be used to perform monitoring as well as provide the management of the cache. In Oracle Utilities Application Framework you can enable Web Application Server JMX monitoring that is unique to the framework by specifying a JMX port number in RMI Port number for JMX Web setting and initial credentials in the JMX Enablement System User ID and JMX Enablement System Password configuration options. These options are available using the configureEnv[.sh] -a utility. Once this is information is supplied a number of configuration files are built (by the initialSetup[.sh] utility) to configure the facility: spl.properties - contains the JMX URL, the security configuration and the mbeans that are enabled. For example, on my demonstration machine: spl.runtime.management.rmi.port=6740 spl.runtime.management.connector.url.default=service:jmx:rmi:///jndi/rmi://localhost:6740/oracle/ouaf/webAppConnector jmx.remote.x.password.file=scripts/ouaf.jmx.password.file jmx.remote.x.access.file=scripts/ouaf.jmx.access.file ouaf.jmx.com.splwg.base.support.management.mbean.JVMInfo=enabled ouaf.jmx.com.splwg.base.web.mbeans.FlushBean=enabled ouaf.jmx.* files - contain the userid and password. The default setup uses the JMX default security configuration. You can use additional security features by altering the spl.properties file manually or using a custom template. For more security options see the JMX Site. Once it has been configured and the changes reflected in the product using the initialSetup[.sh] utility the JMX facility can be used. For illustrative purposes, I will use jconsole but any JSR160 complaint browser or client can be used (with the appropriate configuration). Once you start jconsole (ensure that splenviron[.sh] is executed prior to execution to set the environment variables or for remote connection, ensure java is in your path and jconsole.jar in your classpath) you specify the URL in the spl.management.connnector.url.default entry and the credentials you specified in the jmx.remote.x.* files. Remember these are encrypted by default so if you try and view the file you may be able to decipher it visually. For example: There are three Mbeans available to you: flushBean - This is a JMX replacement for the jsp versions of the flush utilities provided in previous releases of the Oracle Utilities Application Framework. You can manage the cache using the provided operations from JMX. The jsp versions of the flush utilities are still provided, for backward compatibility, but now are authorization controlled. JVMInfo - This is a JMX replacement for the jsp version of the JVMInfo screen used by support to get a handle on JVM information. This information is environmental not operational and is used for support purposes. The jsp versions of the JVMInfo utilities are still provided, for backward compatibility, but now is also authorization controlled. JVMSystem - This is an implementation of the Java system MXBeans for use in monitoring. We provide our own implementation of the base Mbeans to save on creating another JMX configuration for internal monitoring and to provide a consistent interface across platforms for the MXBeans. This Mbean is disabled by default and can be enabled using the enableJVMSystemBeans operation. This Mbean allows for the monitoring of the ClassLoading, Memory, OperatingSystem, Runtime and the Thread MX beans. Refer to the Server Administration Guides provided with your product and the Technical Best Practices Whitepaper for information about individual statistics. The Web Application Server JMX monitoring allows greater visibility for monitoring and management of the Oracle Utilities Application Framework application from jconsole or any JSR160 compliant JMX browser or JMX console.
