• How Service Component Architecture (SCA) Can Be Incorporated Into Existing Enterprise Systems

  After viewing Rob High’s presentation “The SOA Component Model” hosted on InfoQ.com, I can foresee how Service Component Architecture (SCA) can be incorporated in to an existing enterprise. According to IBM’s DeveloperWorks website, SCA is a set of conditions which outline a model for constructing applications/systems using a Service-Oriented Architecture (SOA). In addition, SCA builds on open standards such as Web services. In the future, I can easily see how some large IT shops could potently divide development teams or work groups up into Component/Data Object Groups, and Standard Development Groups. The Component/Data Object Group would only work on creating and maintaining components that are reused throughout the entire enterprise. The Standard Development Group would work on new and existing projects that incorporate the use of various components to accomplish various business tasks. In my opinion the incorporation of SCA in to any IT department will initially slow down the number of new features developed due to the time needed to create the new and loosely-coupled components. However once a company becomes more mature in its SCA process then the number of program features developed will greatly increase. I feel this is due to the fact that the loosely-coupled components needed in order to add the new features will already be built and ready to incorporate into any new development feature request. References: BEA Systems, Cape Clear Software, IBM, Interface21, IONA Technologies PLC, Oracle, Primeton Technologies Ltd, Progress Software, Red Hat Inc., Rogue Wave Software, SAP AG, Siebel Systems, Software AG, Sun Microsystems, Sybase, TIBCO Software Inc.

• The Fantastic New WebLogic on Oracle Database Appliance 2.9 Release is Here!

  - by JuergenKress

  Last week was a big day in virtualised ODA-land as it saw the launch of WebLogic on ODA 2.9. Admittedly it doesn't sound like a very exciting release but it is one that we at O-box have been looking forward to for quite some time. Let me explain why, then we'll look into the details... The ODA X4-2 has 48 Intel Xeon cores. That is a lot of compute power. Whilst the largest O-box SOA Appliance single environment configuration can in theory use all those cores (currently with 40 vCPU of SOA!) the vast majority of O-box users will want smaller configurations. Prior to 2.9 the Oracle WebLogic implementation only supported one domain per ODA, so the conundrum O-box development faced last year was either: offer customers only one SOA environment on their O-box for now (but have the benefit of a standard, easily supportable WebLogic installation), or build our own WebLogic/OTD OVM templates from scratch. One of our driving goals with O-box is to give the best possible experience and make the appliance as supportable as possible. Therefore we took the gamble that we would stick with the Oracle's one-domain WebLogic configuration initially, and just hope that it would deliver multi-domain support for us in a timely manner (note: this is probably not a strategy that business textbooks would recommend!). Anyway, we've been working closely with Oracle Product Management for a few months now and I'm delighted to see 2.9 as the fruits of their labour. This also neatly ties in with several recent requests for O-box to include OSB as well as SOA/BPEL (which we have always wanted to have in separate domains). The diagram below is the neatest way to summarise what the new 2.9 release will allow us to deliver, i.e. previously only one 3D box was possible: Read the complete article here.

• Oracle B2B - Synchronous Request Reply

  - by cdwright

  Introduction So first off, let me say I didn't create this demo (although I did modify it some). I got it from a member of the B2B development technical staff. Since it came with only a simple readme file, I thought I would take some time and write a more detailed explanation about how it works. Beginning with Oracle SOA Suite PS5 (11.1.1.6), B2B supports synchronous request reply over http using the b2b/syncreceiver servlet. I’m attaching the demo to this blog which includes a SOA composite archive that needs to be deployed using JDeveloper, a B2B repository with two agreements that need to be deployed using the B2B console, and a test xml file that gets sent to the b2b/syncreceiver servlet using your favorite SOAP test tool (I'm using Firefox Poster here). You can download the zip file containing the demo here. The demo works by sending the sample xml request file (req.xml) to http://<b2bhost>:8001/b2b/syncreceiver using the SOAP test tool.  The syncreceiver servlet keeps the socket connection open between itself and the test tool so that it can synchronously send the reply message back. When B2B receives the inbound request message, it is passed to the SOA composite through the default B2B Fabric binding. A simple reply is created in BPEL and returned to B2B which then sends the message back to the test tool using that same socket connection. I’ll show you the B2B configuration first, then we’ll look at the soa composite. Configuring B2B No additional configuration necessary in order to use the syncreceiver servlet. It is already running when you start SOA. After importing the GC_SyncReqRep.zip repository file into B2B, you’ll have the typical GlobalChips host trading partner and the Acme remote trading partner. Document Management The repository contains two very simple custom XML document definitions called Orders and OrdersResponse. In order to determine the trading partner agreement needed to process the inbound Orders document, you need to know two things about it; what is it and where it came from. So let’s look at how B2B identifies the appropriate document definition for the message. The XSD’s for these two document definitions themselves are not particularly interesting. Whenever you're dealing with custom XML documents, B2B identifies the appropriate document definition for each XML message using an XPath Identification Expression. The expression is entered for each of these document definitions under the document administration tab in the B2B console. The full XPATH expression for the Orders document is  //*[local-name()='shiporder']/*[local-name()='shipto']/*[local-name()='name']/text(). You can see this path in the XSD diagram below and how it uniquely identifies this message. The OrdersReponse document is identified in the same way. The XPath expression for it is //*[local-name()='Response']/*[local-name()='Status']/text(). You can see how it’s path differs uniquely identifying the reply from the request. Trading Partner Profile The trading partner profiles are very simple too. For GlobalChips, a generic identifier is being used to identify the sender of the response document using the host trading partner name. For Acme, a generic identifier is also being used to identify the sender of the inbound request using the remote trading partner name. The document types are added for the remote trading partner as usual. So the remote trading partner Acme is the sender of the Orders document, and it is the receiver of the OrdersResponse document. For the remote trading partner only, there needs to be a dummy channel which gets used in the outbound response agreement. The channel is not actually used. It is just a necessary place holder that needs to be there when creating the agreement. Trading Partner Agreement The agreements are equally simple. There is no validation and translation is not an option for a custom XML document type. For the InboundAgreement (request) the document definition is set to OrdersDef. In the Agreement Parameters section the generic identifiers have been added for the host and remote trading partners. That’s all that is needed for the inbound transaction. For the OutboundAgreement (response), the document definition is set to OrdersResponseDef and the generic identifiers for the two trading partners are added. The remote trading partner dummy delivery channel is also added to the agreement. SOA Composite Import the SOA composite archive into JDeveloper as an EJB JAR file. Open the composite and you should have a project that looks like this. In the composite, open the b2bInboundSyncSvc exposed service and advance through the setup wizard. Select your Application Server Connection and advance to the Operations window. Notice here that the B2B binding is set to Receive. It is not set for Synchronous Request Reply. Continue advancing through the wizard as you normally would and select finish at the end. Now open BPELProcess1 in the composite. The BPEL process is set as a Synchronous Request Reply as you can see below. The while loop is there just to give the process something to do. The actual reply message is prepared in the assignResponseValues assignment followed by an Invoke of the B2B binding. Open the replyResponse Invoke and go to the properties tab. You’ll see that the fromTradingPartnerId, toTradingPartner, documentTypeName, and documentProtocolRevision properties have been set. Testing the Configuration To test the configuration, I used Firefox Poster. Enter the URL for the b2b/syncreceiver servlet and browse for the req.xml file that contains the test request message. In the Headers tab, add the property ‘from’ and give it the value ‘Acme’. This is how B2B will know where the message is coming from and it will use that information along with the document type name to find the right trading partner agreement. Now post the message. You should get back a response with a status of ‘200 OK’. That’s all there is to it.

• What's safe to assume about the NSMutableArray / NSArray class cluster?

  - by andyvn22

  I know you shouldn't use this to decide whether or not to change an array: if ([possiblyMutable isKindOfClass:[NSMutableArray class]]) But say I'm writing a method and need to return either an NSMutableArray or an NSArray, depending on the mutability of possiblyMutable. The class using my method already knows whether or not it's acceptable to change the returned array. Whether or not it's acceptable to change the returned array directly correlates with whether or not it's acceptable to change possiblyMutable. In that specific case, is this code safe? It seems to me that if it's not acceptable to change the array, but we accidentally get a mutable array, it's ok, because the class using my method won't try to change it. And if it is acceptable to change the array, then we will always get possiblyMutable as an NSMutableArray (though this is the part I'm not entirely clear on). So... safe or not? Alternatives?

• Force memcached to write to all servers in pool

  - by Industrial

  Hi everyone, I have thought a bit on how to make sure that a particular key is distributed to ALL memcached servers in a pool. My current, untested solution is to make another instance of memcached, something like this: $cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50); foreach ($this->cluster() as $cluster) { @$this->tempMemcache = new Memcache; @$this->tempMemcache->connect($cluster['host'], $cluster['port']); @$this->tempMemcache->set($key, $value, $this->compress, $expireTime); @$this->tempMemcache->close(); } What is common sense to do in this case, when certain keys need to be stored on ALL servers for reliability?

• Big Data – Interacting with Hadoop – What is Sqoop? – What is Zookeeper? – Day 17 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned the importance of the Pig and Pig Latin in Big Data Story. In this article we will understand what is Sqoop and Zookeeper in Big Data Story. There are two most important components one should learn when learning about interacting with Hadoop – Sqoop and Zookper. What is Sqoop? Most of the business stores their data in RDBMS as well as other data warehouse solutions. They need a way to move data to the Hadoop system to do various processing and return it back to RDBMS from Hadoop system. The data movement can happen in real time or at various intervals in bulk. We need a tool which can help us move this data from SQL to Hadoop and from Hadoop to SQL. Sqoop (SQL to Hadoop) is such a tool which extract data from non-Hadoop data sources and transform them into the format which Hadoop can use it and later it loads them into HDFS. Essentially it is ETL tool where it Extracts, Transform and Load from SQL to Hadoop. The best part is that it also does extract data from Hadoop and loads them to Non-SQL (or RDBMS) data stores. Essentially, Sqoop is a command line tool which does SQL to Hadoop and Hadoop to SQL. It is a command line interpreter. It creates MapReduce job behinds the scene to import data from an external database to HDFS. It is very effective and easy to learn tool for nonprogrammers. What is Zookeeper? ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. In other words Zookeeper is a replicated synchronization service with eventual consistency. In simpler words – in Hadoop cluster there are many different nodes and one node is master. Let us assume that master node fails due to any reason. In this case, the role of the master node has to be transferred to a different node. The main role of the master node is managing the writers as that task requires persistence in order of writing. In this kind of scenario Zookeeper will assign new master node and make sure that Hadoop cluster performs without any glitch. Zookeeper is the Hadoop’s method of coordinating all the elements of these distributed systems. Here are few of the tasks which Zookeepr is responsible for. Zookeeper manages the entire workflow of starting and stopping various nodes in the Hadoop’s cluster. In Hadoop cluster when any processes need certain configuration to complete the task. Zookeeper makes sure that certain node gets necessary configuration consistently. In case of the master node fails, Zookeepr can assign new master node and make sure cluster works as expected. There many other tasks Zookeeper performance when it is about Hadoop cluster and communication. Basically without the help of Zookeeper it is not possible to design any new fault tolerant distributed application. Tomorrow In tomorrow’s blog post we will discuss about very important components of the Big Data Ecosystem – Big Data Analytics.

• Consolidation in a Database Cloud

  - by B R Clouse

  Consolidation of multiple databases onto a shared infrastructure is the next step after Standardization.  The potential consolidation density is a function of the extent to which the infrastructure is shared.  The three models provide increasing degrees of sharing: Server: each database is deployed in a dedicated VM. Hardware is shared, but most of the software infrastructure is not. Standardization is often applied incompletely since operating environments can be moved as-is onto the shared platform. The potential for VM sprawl is an additional downside. Database: multiple database instances are deployed on a shared software / hardware infrastructure. This model is very efficient and easily implemented with the features in the Oracle Database and supporting products. Many customers have moved to this model and achieved significant, measurable benefits. Schema: multiple schemas are deployed within a single database instance. The most efficient model, it places constraints on the environment. Usually this model will be implemented only by customers deploying their own applications.  (Note that a single deployment can combine Database and Schema consolidations.) Customer value: lower costs, better system utilization In this phase of the maturity model, under-utilized hardware can be used to host more workloads, or retired and those workloads migrated to consolidation platforms. Customers benefit from higher utilization of the hardware resources, resulting in reduced data center floor space, and lower power and cooling costs. And, the OpEx savings from Standardization are multiplied, since there are fewer physical components (both hardware and software) to manage. Customer value: higher productivity The OpEx benefits from Standardization are compounded since not only are there fewer types of things to manage, now there are fewer entities to manage. In this phase, customers discover that their IT staff has time to move away from "day-to-day" tasks and start investing in higher value activities. Database users benefit from consolidating onto shared infrastructures by relieving themselves of the requirement to maintain their own dedicated servers. Also, if the shared infrastructure offers capabilities such as High Availability / Disaster Recovery, which are often beyond the budget and skillset of a standalone database environment, then moving to the consolidation platform can provide access to those capabilities, resulting in less downtime. Capabilities / Characteristics In this phase, customers will typically deploy fixed-size clusters and consolidate on a cluster until that cluster is deemed "full," at which point a new cluster is built. Customers will define one or a few cluster architectures that are used wherever possible; occasionally there may be deployments which must be handled as exceptions. The "full" policy may be based on number of databases deployed on the cluster, or observed peak workload, etc. IT will own the provisioning of new databases on a cluster, making the decision of when and where to place new workloads. Resources may be managed dynamically, e.g., as a priority workload increases, it may be given more CPU and memory to handle the spike. Users will be charged at a fixed, relatively coarse level; or in some cases, no charging will be applied. Activities / Tasks Oracle offers several tools to plan a successful consolidation. Real Application Testing (RAT) has a feature to help plan and validate database consolidations. Enterprise Manager 12c's Cloud Management Pack for Database includes a planning module. Looking ahead, customers should start planning for the Services phase by defining the Service Catalog that will be made available for database services.

• Hello With Oracle Identity Manager Architecture

  - by mustafakaya

  Hi, my name is Mustafa! I'm a Senior Consultant in Fusion Middleware Team and living in Istanbul,Turkey. I worked many various Java based software development projects such as end-to-end web applications, CRM , Telco VAS and integration projects.I want to share my experiences and research about Fusion Middleware Products in this column. Customer always wants best solution from software consultants or developers. Solution will be a code snippet or change complete architecture. We faced different requests according to the case of customer. In my posts i want to discuss Fusion Middleware Products Architecture or how can extend usability with apis or UI customization and more and I look forward to engaging with you on your experiences and thoughts on this.  In my first post, i will be discussing Oracle Identity Manager architecture  and i plan to discuss Oracle Identity Manager 11g features in next posts. Oracle Identity Manager System Architecture Oracle Identity Governance includes Oracle Identity Manager,Oracle Identity Analytics and Oracle Privileged Account Manager. I will discuss Oracle Identity Manager architecture in this post.  In basically, Oracle Identity Manager is a n-tier standard  Java EE application that is deployed on Oracle WebLogic Server and uses  a database .  Oracle Identity Manager presentation tier has three different screen and two different client. Identity Self Service and Identity System Administration are web-based thin client. Design Console is a Java Swing Client that communicates directly with the Business Service Tier.  Identity Self Service provides end-user operations and delegated administration features. System Administration provides system administration functions. And Design Console mostly use for development management operations such as  create and manage adapter and process form,notification , workflow desing, reconciliation rules etc. Business service tier is implemented as an Enterprise JavaBeans(EJB) application. So you can extense Oracle Identity Manager capabilities.  -The SMPL and EJB APIs allow develop custom plug-ins such as management roles or identities.  -Identity Services allow use core business capabilites of Oracle Identity Manager such as The User provisioning or reconciliation service. -Integration Services allow develop custom connectors or adapters for various deployment needs. -Platform Services allow use Entitlement Servers, Scheduler or SOA composites. The Middleware tier allows you using capabilites ADF Faces,SOA Suites, Scheduler, Entitlement Server and BI Publisher Reports. So OIM allows you to configure workflows uses Oracle SOA Suite or define authorization policies use with Oracle Entitlement Server. Also you can customization of OIM UI without need to write code and using ADF Business Editor  you can extend custom attributes to user,role,catalog and other objects. Data tiers; Oracle Identity Manager is driven by data and metadata which provides flexibility and adaptability to Oracle Identity Manager functionlities.  -Database has five schemas these are OIM,SOA,MDS,OPSS and OES. Oracle Identity Manager uses database to store runtime and configuration data. And all of entity, transactional and audit datas are stored in database. -Metadata Store; customizations and personalizations are stored in file-based repository or database-based repository.And Oracle Identity Manager architecture,the metadata is in Oracle Identity Manager database to take advantage of some of the advanced performance and availability features that this mode provides. -Identity Store; Oracle Identity Manager provides the ability to integrate an LDAP-based identity store into Oracle Identity Manager architecture.  Oracle Identity Manager uses the human workflow module of Oracle Service Oriented Architecture Suite. OIM connects to SOA using the T3 URL which is front-end URL for the SOA server.Oracle Identity Manager uses embedded Oracle Entitlement Server for authorization checks in OIM engine.  Several Oracle Identity Manager modules use JMS queues. Each queue is processed by a separate Message Driven Bean (MDB), which is also part of the Oracle Identity Manager application. Message producers are also part of the Oracle Identity Manager application. Oracle Identity Manager uses a scheduled jobs for some activities in the background.Some of scheduled jobs come with Out-Of-Box such as the disable users after the end date of the users or you can define your custom schedule jobs with Oracle Identity Manager APIs. You can use Oracle BI Publisher for reporting Oracle Identity Manager transactions or audit data which are in database. About me: Mustafa Kaya is a Senior Consultant in Oracle Fusion Middleware Team, living in Istanbul. Before coming to Oracle, he worked in teams developing web applications and backend services at a telco company. He is a Java technology enthusiast, software engineer and addicted to learn new technologies,develop new ideas.

• OSB/OSR/OER in One Domain - QName violates loader constraints

  - by John Graves

  For demos, testing and prototyping, I wanted a single domain which contained three servers:OSB - Oracle Service BusOSR - Oracle Service RegistryOER - Oracle Enterprise Repository These three can work together to help with service governance in an enterprise.  When building out the domain, I found errors in the OSR server due to some conflicting classes from the OSB.  This wouldn't be an issue if each server was given a unique classpath setting with the node manager, but I was having the node manager use the standard startup scripts. The domain's bin/setDomainEnv.sh script has a large set of extra libraries added for OSB which look like this: if [ "${POST_CLASSPATH}" != "" ] ; then POST_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jrf_11.1.1/jrf.jar${CLASSPATHSEP}${POST_CLASSPATH}" export POST_CLASSPATH else POST_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jrf_11.1.1/jrf.jar" export POST_CLASSPATH fi if [ "${PRE_CLASSPATH}" != "" ] ; then PRE_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jdbc_11.1.1/ojdbc6dms.jar${CLASSPATHSEP}${PRE_CLASSPATH}" export PRE_CLASSPATH else PRE_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jdbc_11.1.1/ojdbc6dms.jar" export PRE_CLASSPATH fi POST_CLASSPATH="${POST_CLASSPATH}${CLASSPATHSEP}/oracle/fmwhome/Oracle_OSB1/soa/modules/oracle.soa.common.adapters_11.1.1/oracle.soa.common.adapters.jar\ ${CLASSPATHSEP}${ALSB_HOME}/lib/version.jar\ ${CLASSPATHSEP}${ALSB_HOME}/lib/alsb.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-ant.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-common.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-core.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-dameon.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/classes${CLASSPATHSEP}\ ${ALSB_HOME}/lib/external/log4j_1.2.8.jar${CLASSPATHSEP}\ ${DOMAIN_HOME}/config/osb" I didn't take the time to sort out exactly which jar was causing the problem, but I simply surrounded this block with a conditional statement: if [ "${SERVER_NAME}" == "osr_server1" ] ; then POST_CLASSPATH=""else if [ "${POST_CLASSPATH}" != "" ] ; then POST_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jrf_11.1.1/jrf.jar${CLASSPATHSEP}${POST_CLASSPATH}" export POST_CLASSPATH else POST_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jrf_11.1.1/jrf.jar" export POST_CLASSPATH fi if [ "${PRE_CLASSPATH}" != "" ] ; then PRE_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jdbc_11.1.1/ojdbc6dms.jar${CLASSPATHSEP}${PRE_CLASSPATH}" export PRE_CLASSPATH else PRE_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/oracle.jdbc_11.1.1/ojdbc6dms.jar" export PRE_CLASSPATH fi POST_CLASSPATH="${POST_CLASSPATH}${CLASSPATHSEP}/oracle/fmwhome/Oracle_OSB1/soa/modules/oracle.soa.common.adapters_11.1.1/oracle.soa.common.adapters.jar\ ${CLASSPATHSEP}${ALSB_HOME}/lib/version.jar\ ${CLASSPATHSEP}${ALSB_HOME}/lib/alsb.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-ant.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-common.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-core.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/lib/j2ssh-dameon.jar\ ${CLASSPATHSEP}${ALSB_HOME}/3rdparty/classes${CLASSPATHSEP}\ ${ALSB_HOME}/lib/external/log4j_1.2.8.jar${CLASSPATHSEP}\ ${DOMAIN_HOME}/config/osb" fi I could have also just done an if [ ${SERVER_NAME} = "osb_server1" ], but I would have also had to include the AdminServer because they are needed there too.  Since the oer_server1 didn't mind, I did the negative case as shown above.

• Help me classify this type of software architecture

  - by Alex Burtsev

  I read some books about software architecture as we are using it in our project but I can't classify the architecture properly. It's some kind of Enterprise Architecture, but what exactly... SOA, ESB (Enterprise Service Bus), Message Bus, Event Driven SOA, there are so many terms in Enterprise software.... The system is based on custom XML messages exchanges between services. (it's not SOAP, nor any other XML based standard, just plain XML). These messages represent notifications (state changes) that are applied to the Domain model, (it's not like CRUD when you serialize the whole domain object, and pass it to service for persistence). The system is centralized, and system participants use different programming languages and frameworks (c++, c#, java). Also, messages are not processed at the moment they are received as they are stored first and the treatment begins on demand. It's called SOA+EDA -:)

• Use of Hibernate 3.0 with EJB 3.0 & JPA

  - by SOA Nerd

  Where I'm working the guys that are sitting across from me are working on a project. This is a JavaEE app which uses Struts, Spring, EJB 3.0, JPA, and Hibernate 3.0. They are using EJB 3.0 entity beans with annotations. I've been asking them why Hibernate 3.0 is in this mix and noone can seem to tell me. It feels like they've included Hibernate 3.0 because they were told to but are not using it for anything that they can't get from EJB 3.0 entity beans/JPA. They're using CMP and accessing all of the database functions via EJBs. Can Hibernate give you anything in this setup that can't be provided by EJB 3.0/JPA?

• Understanding the SQL Server 2008 R2 Installation Center

  - by Enrique Lima

  What is available to us through those links?  Have you taken the time to explore and identify what could be useful to you? One of many gems that has come to my attention is the possibility of provisioning SQL Server to work in an image based environment (hint: Virtualization Template perhaps?!?).   Planning: Includes requirements information, documentation, how to guides, online documentation installation and other tools. Among the other tools you will find the System Configuration checker and The Upgrade Advisor. Both tools very important to ensure your deployment and installation would be successful.     Installation:  This sections focuses on getting installations going, from standalone to cluster when it comes to new instances.  Add new nodes to an existing cluster, and also perform upgrades (in this case to SQL Server 2008 R2).  Also part of this is the option to find updates available.   Maintenance: We find in this section, options that will assist us in tasks like repairing corrupt installations to removing nodes from a cluster. An option that is interesting (and we should discuss benefits later in another post) is to be able to do an Edition Upgrade, this is a feature expansion and addition based on your product installation (Developer to Enterprise, for example)   Tools:  From the System Configuration Checker to identify readiness for deployment in a successful manner, to being able to report on features installed.  And being able to run upgrades of existing packages developed in the 2005 offering to the 2008 R2 release for SSIS.   Resources: Useful and essential links to gather information and guidance.   Advanced: Here is where it gets interesting.  I break this down into 3 main groups: Installation Automation: When you install SQL Server there is a configuration file that gets dropped (ConfigurationFile.ini) that would allow for you to perform automated installations.  There are switches and options that go with this to have that process working. Cluster configuration for Sysprep: Create images that are cluster ready, 2 options, start the prep work, and then the complete once at the final destination. Stand-alone configuration for Sysprep:  Like the clustering counterpart, 2 options, prep and complete.  Giving you the option to create standard templates for your SQL Server deployments. I find it fitting that the 3 topics listed here should (and will) be additional topics I will discuss.   Options: Very clear and specific about what this means. Select the Processor Type or the Installation Media Root Path.

• Migration of VM from Hyper-V to Hyper-V R2 - Pass through disks

  - by Andrew Gillen

  I am trying to migrate a VM which is using two pass through disks from a legacy Hyper-V Cluster to a new R2 cluster. The migrated VM cannot use the pass through disks though. The guest OS (2008 R2) doesn't seem to like the disk and eventually tries to format the disk instead of mounting it. The migration process I have been using for all my VMs is to export the VM to a new lun, then add that new lun to the new cluster, importing the vm off it in the hyper-v console, then making it highly available. I assumed I could do the same thing and just add the two pass through disks to the new cluster and then attach them inside Hyper-V. Is there a process I need to follow to migrate pass through disks that does not involve setting up new Luns and robocopying the data over?

• Amazon AWS EC2 + Puppet, get Puppet to know AWS instance tags

  - by Piotr Jasiulewicz

  I am having a problem with my AWS deployment, fairly new to AWS and Puppet. So coming to my question - can you distinguish puppet nodes with AWS machine tags or CNAME domains? A little background about the plan: have multiple clusters of machines, one php cluster, one legacy php cluster, one java cluster, one perl cluster control configuration with puppet - still pretty new to puppet but as a developer I like the idea of being able to version control configuration of servers have autoscaling enabled on those clusters - obviously the main benefit of the cloud that makes the much hight cost when it comes to any reasonable performance worth it (those amazon machines are slower than my phone...) deployment controlled by Capistrano, this makes things a lot easier So in AWS you get those super nasty public/private machine dns's... no way you can identify machines on those. In order to easer the problem, seams like AWS want's you to tag everything - so I did. Found a script that makes a CNAME record for each machine with the tag "ShortName" thanks to the Route53 API. Every machine has a ShortName tag that becomes its CNAME, unfortunately puppet still resolves the private dns name. I'd like to have node 'perl-cluster'{} in puppet, anyone any clue ho to achieve this? Thanks

• Reset Network Load Balancer Connection Pool

  - by bill_the_loser

  I am currently working on load testing a web application on a virtual machine cluster. I am looking for a way to flush the connection pool / NLB cache so that it is like each machine connecting to the NLB is connecting for the first time and doesn't get directed back to the node that it was on last time. This a Windows 2003 Server cluster, behind a Microsoft software based Network Load Balancer. Additional Information: To do the load testing I'm using virtual machines, one for each node on the cluster. Somehow I got two virtual machines connecting to the same node and I'm looking for an easier way to reset those connections without going in to the NLB Manager and stopping and starting each node on the NLB. Update: We went ahead and changed the affinity on all of the nodes of the cluster to none. Now it's a non-issue.

• OpenLDAP replication fails, "syncrepl_entry: rid=666 be_modify failed (20)"

  I've configured a second host to replicate the main LDAP server via syncrepl in the slapd.conf: syncrepl rid=666 provider=ldaps://my-main-server.com type=refreshAndPersist searchBase="dc=Staff,dc=my-main-server,dc=com" filter="(objectClass=*)" scope=sub schemachecking=off bindmethod=simple binddn="cn=repadmin,dc=my-main-server,dc=com" credentials=mypassword When I restart slapd, it writes to /var/log/debug Jun 11 15:48:33 cluster-mn-04 slapd[29441]: @(#) $OpenLDAP: slapd 2.4.9 (Mar 31 2009 07:18:37) $ ^Ibuildd@yellow:/build/buildd/openldap2.3-2.4.9/debian/build/servers/slapd Jun 11 15:48:34 cluster-mn-04 slapd[29442]: slapd starting Jun 11 15:48:34 cluster-mn-04 slapd[29442]: null_callback : error code 0x14 Jun 11 15:48:34 cluster-mn-04 slapd[29442]: syncrepl_entry: rid=666 be_modify failed (20) Jun 11 15:48:34 cluster-mn-04 slapd[29442]: do_syncrepl: rid=666 quitting I've looked into the sources for the return code and found only #define LDAP_TYPE_OR_VALUE_EXISTS 0x14 in include/ldap.h. Anyway, I don't quite get what the error message means. Can you help me debugging this problem and figure out why the LDAP replication doesn't work? I've managed to put a "manual" copy via slapcat and slapadd into the database, but I'd like to sync automatically. UPDATE: "Solved" by removing /var/lib/ldap/* and re-importing the database with slapadd.
