  • Installing Oracle Event Processing 11g by Antoney Reynolds

    - by JuergenKress
    Earlier this month I was involved in organizing the Monument Family History Day. It was certainly a complex event, with dozens of presenters, guides and 100s of visitors. So with that experience of a complex event under my belt I decided to refresh my acquaintance with Oracle Event Processing (CEP). CEP has a developer side based on Eclipse and a runtime environment. Server install The server install is very straightforward (documentation). It is recommended to use the JRockit JDK with CEP so the steps to set up a working CEP server environment are: Download required software JRockit - I used Oracle “JRockit 6 - R28.2.5” which includes “JRockit Mission Control 4.1” and “JRockit Real Time 4.1”. Oracle Event Processor - I used “Complex Event Processing Release 11gR1 (11.1.1.6.0)” Install JRockit Run the JRockit installer, the download is an executable binary that just needs to be marked as executable. Install CEP Unzip the downloaded file Run the CEP installer, the unzipped file is an executable binary that may need to be marked as executable. Choose a custom install and add the examples if needed. It is not recommended to add the examples to a production environment but they can be helpful in development. Developer Install The developer install requires several steps (documentation). A developer install needs access to the software for the server install, although JRockit isn’t necessary for development use. Read the full article by Antony Reynolds.

  • Deploying Fusion Order Demo on 11.1.1.6 by Antony Reynolds

    - by JuergenKress
    Do you need to build a demo for a customer? Why not to use Fusion Order Demo (FOD) and modify it to do some extra things. Great idea, let me install it on one of my Linux servers I said "Turns out there are a few gotchas, so here is how I installed it on a Linux server with JDeveloper on my Windows desktop." Task 1: Install Oracle JDeveloper Studio I already had JDeveloper 11.1.1.6 with SOA extensions installed so this was easy. Task 2: Install the Fusion Order Demo Application First thing to do is to obtain the latest version of the demo from OTN, I obtained the R1 PS5 release. Gotcha #1 – my winzip wouldn’t unzip the file, I had to use 7-Zip. Task 3: Install Oracle SOA Suite On the domain modify the setDomainEnv script by adding “-Djps.app.credential.overwrite.allowed=true” to JAVA_PROPERTIES and restarting the Admin Server. Also set the JAVA_HOME variable and add Ant to the path. I created a domain with separate SOA and BAM servers and also set up the Node Manager to make it easier to stop and start components.

  • IASA South East Florida Chapter Meeting Recap - June 2011

    - by Sam Abraham
    Erik Russell and Giles Marino were our speakers for the June 2011 IASA South East Florida Chapter meeting.    Attendees filled all available seats at the Microsoft office conference room where the event was held. This highlights the high interest in Enterprise Architecture as a career track and chartered project role. Also in attendance were our Board of Directors and Alex Funkhouser, President, Sherlock Technology.   Rainer Habermann, Chapter President, kicked off the meeting by introducing our speakers and Board of Directors.   Alex Funkhouser, President of South Florida’s staffing firm Sherlock Technology spoke briefly about available Software Architect positions in the area. Alex also congratulated and presented this week’s Sherlock Raffle winner with $500 in cash.   Our speakers Giles and Erik then proceeded with their talk. Erik presented a business case in the government sector where Enterprise Architecture helped a government entity cut costs and streamline its various business operations. Technologies leveraged in Erik’s demonstrated project were Java-based.   Giles then followed with a thorough demonstration of the Architecture patterns he used to migrate a complete backend system for an insurance company to the .Net Platform.   Audience was very engaged with our speakers as evidenced by the large number of follow-up questions asked at the end of the talk.   We greatly enjoyed Giles and Erik’s talk and look forward to having them share with us more of their adventures as Enterprise Architects in the near future.   Below are some photos of the event.   Sam Abraham Secretary- IASA South East Florida Chapter. http://www.iasaglobal.org/iasa/South_East_Florida.asp Chapter President - Rainer Habermann kicks off our meeting.   Sherlock Technology President Alex Funkhouser holding Sherlock's weekly cash prize.

  • Visual Studio Talk Show #118 is now online - Command-Query Responsibility Separation (French)

    - by guybarrette
    http://www.visualstudiotalkshow.com Erik Renaud: La séparation des responsabilités entre les commandes et les requêtes Nous discutons avec Erik Renaud de la séparation des responsabilités entre les commandes et les requêtes (Command-Query Responsibility Separation - CQRS). La plupart des applications lisent les données beaucoup plus fréquemment qu'ils font des écritures. Sur la base de cette déclaration, une bonne idée consiste à séparer le code qui est responsable de l’écriture des données du code qui est responsable des requêtes (lecture). Erik Renaud est un coach .NET et co-fondateur de nVentive, une société conseil qui aide les équipes de développement logiciel au moyen de « coaching » et de « guidance ». Ses mandats courants se concentrent dans les grandes institutions financières en créant de nouvelles équipes qui supportent directement leurs activités primaires. Erik cumule plus de 10 ans d’expérience en développement logiciel, en faisant du coaching pour des équipes pour des besoins en architecture, modélisation et analyse. Pour la seconde année, il a reçu de Microsoft la reconnaissance MVP. Il est un ScrumMaster certifié, ce qui l’aide à guider les équipes vers le succès, et offre souvent des formations pour les technologies orientées objet.

  • Changed Password Won't seem to work for account

    - by erik
    Bit of an odd problem. I've got a server I can SSH into as one of two logins: root or erik. Once I've logged in as erik I've tried to switch to the root user: # sudo su - root Password: And entered the password. After several failures I thought I might have forgotten. So I SSH'd in as root, and changed the root password: # passwd Now back to the other shell (erik) and attempt to run sudo su - root and again, it won't accept the just changed password. Any ideas?

    Complete noob here. I am trying to install Ubuntu 12.04 from a Live CD. I told the computer to boot from the CD (it does) & it reads the CD & then quits with the Ubuntu dots just freezing. I checked the disk & did the memory test, both OK. I also did the nomodeset in the start-up line. Hit escape when it froze but there were no msgs. Have also tried Ubuntu 12.10 & Dream Studio, same thing. Anyone have any ideas? Thanks! Erik The Pope

  • How to penetrate the QA industry after layoffs, next steps...

    - by Erik
    Briefly, my background is in manual black box testing of websites and applications within the Agile/waterfall context. Over the past four years I was a member of two web development firms' small QA teams dedicated to testing the deployment of websites for national/international non profits, governmental organizations, and for profit business, to name a few: -Brookings Institution -Senate -Tyco Electronics -Blue Cross/Blue Shield -National Geographic -Discover Channel I have a very strong understanding of the: -SDLC -STLC of bugs and website deployment/development -Use Case & Test Case development In March of this year, my last firm downsized and lost my job as a QA tester. I have been networking and doing a very detailed job search, but have had a very difficult time getting my next job within the QA industry, even with my background as a manual black box QA tester in the website development context. My direct question to all of you: What are some ways I can be more competitive and get hired? Options that could get me competitive: Should I go back to school and learn some more 'hard' skills in website development and client side technologies, e.g.: -HTML -CSS -JavaScript Learn programming: -PHP -C# -Ruby -SQL -Python -Perl -?? Get Certified as a QA Tester, there are a countless numbers of programs to become a Certified Tester. Most, if not all jobs, being advertised now require Automated Testing experience, in: -QTP -Loadrunner -Selenium -ETC. Should I learn, Automated testing skills, via a paid course, or teach myself? --Learn scripting languages to understand the automated testing process better? Become a Certified "Project Management Professional" (PMP) to prove to hiring managers that I 'get' the project development life cycle? At the end of the day I need to be competitive and get hired as a QA tester and want to build upon my skills within the QA web development field. How should I do this, without reinventing the wheel? Any help in this regard would be fabulous. Thanks! .erik

  • crash when using wireless network

    - by Erik
    ubuntu 12.04 32 bit When I start up my system almost instantly freezes, I found that the problem lays with my wireless network, because the crash is always t the same time as the message that tells me I am connected to a network when I start up connected to a cable everything works fine, I can even see that I am connected to our wireless network, until I unplug the ethernet cable, then it all freezes again the same happened when I boot from a live cd (from usb) The problem only occurs on my netbook, my laptop doesn't give any problems. I don't know if anyone else has had similar problems, or if anyone knows a solution... Thanks in advance! greetings Erik EDIT (21/3/2012): it seems there is some external factor involved, I'm using my netbook for about 50 minutes now while connected to the wireless network, and still it didn't crash strange enough, before these 50 minutes I had to put it down by holding the power button, because I decided to try it again, that time it did crash... before (while connected with an ethernet cable) I've been trying to get my Bluetooth working, that didn't succeed entirely, but I guess that might be a factor in the question why it doesn't crash at the moment now I rebooted, connected, and no crash... if it crashes again, I'll update this post again. in the meantime, if anyone has an idea on what could be a factor, and on how to create a crash using that factor, feel free to ask!

I'd wake up cheerful and then before I go to bed I already feel depressed.  I have no idea what triggers it.  On the bed, I'd turn my back to my wife, curl up into a fetal position and start sobbing silently. Awful.  Maybe you're wondering now what's the cause of all this.My grandma passed away and I haven't completely  come to terms with that fact.  I long to see her, talk to her and hold her... but I can't do that anymore because she's gone.  I will never be able to hear her voice and feel her touch again.  To make matters worse, the only person whom I wish would stay beside me whenever I'm feeling miserable and dejected is never around.  She's either working late or out with her friends.  Such is my life at the moment.  I doubt it will improve anytime soon.

    Hi, A time ago I had a script who got the flv-file from a specified youtube-video, which now is broken due to changes at their website. I am wondering if Youtube may have an API to download the flv-file, where can I find it in that case? Have anyone build an own script, may someone wanna help be building it? Is there any scripts in any other languages such as shell/bash that works? :) Best regards, Erik Persson

  • DDD Modeling questions : student, classroom, seats and a favorite seat for a student.

    - by Erik Ashepa
    Hi, i'm not sure how to model this relationship... A classroom contains many seats, every student studies in a classroom and have a favorite seat within it. The way i see it, i have two aggregate roots: classroom and student, seats a are entities aggregatged by classroom... And for a student to have a fovorite seat, it must hold a reference to it (seat isn't an aggregate root). Any suggestions? Thanks in advance, Erik.

  • How to use Python list comprehension (or such) for retrieving rows when using MySQLdb?

    - by Erik Nygren
    Hey all, I use MySQLdb a lot when dealing with my webserver. I often find myself repeating the lines: row = cursor.fetchone() while row: do_processing(row) row = cursor.fetchone() Somehow this strikes me as somewhat un-pythonic. Is there a better, one-line way to accomplish the same thing, along the lines of inline assignment in C: while (row = do_fetch()) { do_processing(row); } I've tried figuring out the syntax using list comprehensions, but I can't seem to figure it out. Any recommendations? Thanks, Erik

  • Security in OBIEE 11g, Part 2

    - by Rob Reynolds
    Continuing the series on OBIEE 11g, our guest blogger this week is Pravin Janardanam. Here is Part 2 of his overview of Security in OBIEE 11g. OBIEE 11g Security Overview, Part 2 by Pravin Janardanam In my previous blog on Security, I discussed the OBIEE 11g changes regarding Authentication mechanism, RPD protection and encryption. This blog will include a discussion about OBIEE 11g Authorization and other Security aspects. Authorization: Authorization in 10g was achieved using a combination of Users, Groups and association of privileges and object permissions to users and Groups. Two keys changes to Authorization in OBIEE 11g are: Application Roles Policies / Permission Groups Application Roles are introduced in OBIEE 11g. An application role is specific to the application. They can be mapped to other application roles defined in the same application scope and also to enterprise users or groups, and they are used in authorization decisions. Application roles in 11g take the place of Groups in 10g within OBIEE application. In OBIEE 10g, any changes to corporate LDAP groups require a corresponding change to Groups and their permission assignment. In OBIEE 11g, Application roles provide insulation between permission definitions and corporate LDAP Groups. Permissions are defined at Application Role level and changes to LDAP groups just require a reassignment of the Group to the Application Roles. Permissions and privileges are assigned to Application Roles and users in OBIEE 11g compared to Groups and Users in 10g. The diagram below shows the relationship between users, groups and application roles. Note that the Groups shown in the diagram refer to LDAP Groups (WebLogic Groups by default) and not OBIEE application Groups. The following screenshot compares the permission windows from Admin tool in 10g vs 11g. Note that the Groups in the OBIEE 10g are replaced with Application Roles in OBIEE 11g. The same is applicable to OBIEE web catalog objects.    The default Application Roles available after OBIEE 11g installation are BIAdministrator, BISystem, BIConsumer and BIAuthor. Application policies are the authorization policies that an application relies upon for controlling access to its resources. An Application Role is defined by the Application Policy. The following screenshot shows the policies defined for BIAdministrator and BISystem Roles. Note that the permission for impersonation is granted to BISystem Role. In OBIEE 10g, the permission to manage repositories and Impersonation were assigned to “Administrators” group with no control to separate these permissions in the Administrators group. Hence user “Administrator” also had the permission to impersonate. In OBI11g, BIAdministrator does not have the permission to impersonate. This gives more flexibility to have multiple users perform different administrative functions. Application Roles, Policies, association of Policies to application roles and association of users and groups to application roles are managed using Fusion Middleware Enterprise Manager (FMW EM). They reside in the policy store, identified by the system-jazn-data.xml file. The screenshots below show where they are created and managed in FMW EM. The following screenshot shows the assignment of WebLogic Groups to Application Roles. The following screenshot shows the assignment of Permissions to Application Roles (Application Policies). Note: Object level permission association to Applications Roles resides in the RPD for repository objects. Permissions and Privilege for web catalog objects resides in the OBIEE Web Catalog. Wherever Groups were used in the web catalog and RPD has been replaced with Application roles in OBIEE 11g. Following are the tools used in OBIEE 11g Security Administration: ·       Users and Groups are managed in Oracle WebLogic Administration console (by default). If WebLogic is integrated with other LDAP products, then Users and Groups needs to managed using the interface provide by the respective LDAP vendor – New in OBIEE 11g ·       Application Roles and Application Policies are managed in Oracle Enterprise Manager - Fusion Middleware Control – New in OBIEE 11g ·       Repository object permissions are managed in OBIEE Administration tool – Same as 10g but the assignment is to Application Roles instead of Groups ·       Presentation Services Catalog Permissions and Privileges are managed in OBI Application administration page - Same as 10g but the assignment is to Application Roles instead of Groups Credential Store: Credential Store is a single consolidated service provider to store and manage the application credentials securely. The credential store contains credentials that either user supplied or system generated. Credential store in OBIEE 10g is file based and is managed using cryptotools utility. In 11g, Credential store can be managed directly from the FMW Enterprise Manager and is stored in cwallet.sso file. By default, the Credential Store stores password for deployed RPDs, BI Publisher data sources and BISystem user. In addition, Credential store can be LDAP based but only Oracle Internet Directory is supported right now. As you can see OBIEE security is integrated with Oracle Fusion Middleware security architecture. This provides a common security framework for all components of Business Intelligence and Fusion Middleware applications.

  • Gone With the Wind?

    - by antony.reynolds
    Where Have All the Composites Gone? I was just asked to help out with an interesting problem at a customer.  All their composites had disappeared from the EM console, none of them showed as loading in the log files and there was an ominous error message in the logs. Symptoms After a server restart the customer noticed that none of his composites were available, they didn’t show in the EM console and in the log files they saw this error message: SEVERE: WLSFabricKernelInitializer.getCompositeList Error during parsing and processing of deployed-composites.xml file This indicates some sort of problem when parsing the deployed-composites.xml file.  This is very bad because the deployed-composites.xml file is basically the table of contents that tells SOA Infrastructure what composites to load and where to find them in MDS.  If you can’t read this file you can’t load any composites and your SOA Server now has all the utility of a chocolate teapot. Verification We can look at the deployed-composites.xml file from MDS either by connecting JDeveloper to MDS, exporting the file using WLST or exporting the whole soa-infra MDS partition by using EM->SOA->soa-infra->Administration->MDS Configuration.  Exporting via EM is probably the easiest because it then prepares you to fix the problem later.  After exporting the partition to local storage on the SOA Server I then ran an XSLT transform across the file deployed-composites/deployed-composites.xml. <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/1999/xhtml">     <xsl:output indent="yes"/>     <xsl:template match="/">         <testResult>             <composite-series>                 <xsl:attribute name="elementCount"><xsl:value-of select="count(deployed-composites/composite-series)"/></xsl:attribute>                 <xsl:attribute name="nameAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series[@name])"/></xsl:attribute>                 <xsl:attribute name="defaultAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series[@default])"/></xsl:attribute>                 <composite-revision>                     <xsl:attribute name="elementCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision)"/></xsl:attribute>                     <xsl:attribute name="dnAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision[@dn])"/></xsl:attribute>                     <xsl:attribute name="stateAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision[@state])"/></xsl:attribute>                     <xsl:attribute name="modeAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision[@mode])"/></xsl:attribute>                     <xsl:attribute name="locationAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision[@location])"/></xsl:attribute>                     <composite>                         <xsl:attribute name="elementCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision/composite)"/></xsl:attribute>                         <xsl:attribute name="dnAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision/composite[@dn])"/></xsl:attribute>                         <xsl:attribute name="deployedTimeAttributeCount"><xsl:value-of select="count(deployed-composites/composite-series/composite-revision/composite[@deployedTime])"/></xsl:attribute>                     </composite>                 </composite-revision>                 <xsl:apply-templates select="deployed-composites/composite-series"/>             </composite-series>         </testResult>     </xsl:template>     <xsl:template match="composite-series">             <xsl:if test="not(@name) or not(@default) or composite-revision[not(@dn) or not(@state) or not(@mode) or not(@location)]">                 <ErrorNode>                     <xsl:attribute name="elementPos"><xsl:value-of select="position()"/></xsl:attribute>                     <xsl:copy-of select="."/>                 </ErrorNode>             </xsl:if>     </xsl:template> </xsl:stylesheet> The output from this is not pretty but it shows any <composite-series> tags that are missing expected attributes (name and default).  It also shows how many composites are in the file (111) and how many revisions of those composites (115). <?xml version="1.0" encoding="UTF-8"?> <testResult xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/1999/xhtml">    <composite-series elementCount="111" nameAttributeCount="110" defaultAttributeCount="110">       <composite-revision elementCount="115" dnAttributeCount="114" stateAttributeCount="115"                           modeAttributeCount="115"                           locationAttributeCount="114">          <composite elementCount="115" dnAttributeCount="114" deployedTimeAttributeCount="115"/>       </composite-revision>       <ErrorNode elementPos="82">          <composite-series xmlns="">             <composite-revision state="on" mode="active">                <composite deployedTime="2010-12-15T11:50:16.067+01:00"/>             </composite-revision>          </composite-series>       </ErrorNode>    </composite-series> </testResult> From this I could see that one of the <composite-series> elements (number 82 of 111) seemed to be corrupt. Having found the problem I now needed to fix it. Fixing the Problem The solution was really quite easy.  First for safeties sake I took a backup of the exported MDS partition.  I then edited the deployed-composites/deployed-composites.xml file to remove the offending <composite-series> tag. Finally I restarted the SOA domain and was rewarded by seeing that the deployed composites were now visible. Summary One possible cause of not being able to see deployed composites after a SOA 11g system restart is a corrupt deployed-composites.xml file.  Retrieving this file from MDS, repairing it, and replacing it back into MDS can solve the problem.  This still leaves the problem of how did this file become corrupt!

  • Cold Start

    - by antony.reynolds
    Well we had snow drifts 3ft deep on Saturday so it must be spring time.  In preparation for Spring we decided to move the lawn tractor.  Of course after sitting in the garage all winter it refused to start.  I then come into the office and need to start my 11g SOA Suite installation.  I thought about this and decided my tractor might be cranky but at least I can script the startup of my SOA Suite 11g installation. So with this in mind I created 6 scripts.  I created them for Linux but they should translate to Windows without too many problems.  This is left as an exercise to the reader, note you will have to hardcode more than I did in the Linux scripts and create separate script files for the sqlplus and WLST sections. Order to start things I believe there should be order in all things, especially starting the SOA Suite.  So here is my preferred order. Start Database This is need by EM and the rest of SOA Suite so best to start it before the Admin Server and managed servers. Start Node Manager on all machines This is needed if you want the scripts to work across machines. Start Admin Server Once this is done in theory you can manually stat the managed servers using WebLogic console.  But then you have to wait for console to be available.  Scripting it all is quicker and easier way of starting. Start Managed Servers & Clusters Best to start them one per physical machine at a time to avoid undue load on the machines.  Non-clustered install will have just soa_server1 and bam_serv1 by default.  Clusters will have at least SOA and BAM clusters that can be started as a group or individually.  I have provided scripts for standalone servers, but easy to change them to work with clusters. Starting Database I have provided a very primitive script (available here) to start the database, the listener and the DB console.  The section highlighted in red needs to match your database name. #!/bin/sh echo "##############################" echo "# Setting Oracle Environment #" echo "##############################" . oraenv <<-EOF orcl EOF echo "#####################" echo "# Starting Database #" echo "#####################" sqlplus / as sysdba <<-EOF startup exit EOF echo "#####################" echo "# Starting Listener #" echo "#####################" lsnrctl start echo "######################" echo "# Starting dbConsole #" echo "######################" emctl start dbconsole read -p "Hit <enter> to continue" Starting SOA Suite My script for starting the SOA Suite (available here) breaks the task down into five sections. Setting the Environment First set up the environment variables.  The variables highlighted in red probably need changing for your environment. #!/bin/sh echo "###########################" echo "# Setting SOA Environment #" echo "###########################" export MW_HOME=~oracle/Middleware11gPS1 export WL_HOME=$MW_HOME/wlserver_10.3 export ORACLE_HOME=$MW_HOME/Oracle_SOA export DOMAIN_NAME=soa_std_domain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME Starting the Node Manager I start node manager with a nohup to stop it exiting when the script terminates and I redirect the standard output and standard error to a file in a logs directory. cd $DOMAIN_HOME echo "#########################" echo "# Starting Node Manager #" echo "#########################" nohup $WL_HOME/server/bin/startNodeManager.sh >logs/NodeManager.out 2>&1 & Starting the Admin Server I had problems starting the Admin Server from Node Manager so I decided to start it using the command line script.  I again use nohup and redirect output. echo "#########################" echo "# Starting Admin Server #" echo "#########################" nohup ./startWebLogic.sh >logs/AdminServer.out 2>&1 & Starting the Managed Servers I then used WLST (WebLogic Scripting Tool) to start the managed servers.  First I waited for the Admin Server to come up by putting a connect command in a loop.  I could have put the WLST commands into a separate script file but I wanted to reduce the number of files I was using and so used redirected input (here syntax). $ORACLE_HOME/common/bin/wlst.sh <<-EOF import time sleep=time.sleep print "#####################################" print "# Waiting for Admin Server to Start #" print "#####################################" while True:   try:     connect(adminServerName="AdminServer")     break   except:     sleep(10) I then start the SOA server and tell WLST to wait until it is started before returning.  If starting a cluster then the start command would be modified accordingly to start the SOA cluster. print "#######################" print "# Starting SOA Server #" print "#######################" start(name="soa_server1", block="true") I then start the BAM server in the same way as the SOA server. print "#######################" print "# Starting BAM Server #" print "#######################" start(name="bam_server1", block="true") EOF Finally I let people know the servers are up and wait for input in case I am running in a separate window, in which case the result would be lost without the read command. echo "#####################" echo "# SOA Suite Started #" echo "#####################" read -p "Hit <enter> to continue" Stopping the SOA Suite My script for shutting down the SOA Suite (available here)  is basically the reverse of my startup script.  After setting the environment I connect to the Admin Server using WLST and shut down the managed servers and the admin server.  Again the script would need modifying for a cluster. Stopping the Servers If I cannot connect to the Admin Server I try to connect to the node manager, in case the Admin Server is down but the managed servers are up. #!/bin/sh echo "###########################" echo "# Setting SOA Environment #" echo "###########################" export MW_HOME=~oracle/Middleware11gPS1 export WL_HOME=$MW_HOME/wlserver_10.3 export ORACLE_HOME=$MW_HOME/Oracle_SOA export DOMAIN_NAME=soa_std_domain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME cd $DOMAIN_HOME $MW_HOME/Oracle_SOA/common/bin/wlst.sh <<-EOF try:   print("#############################")   print("# Connecting to AdminServer #")   print("#############################")   connect(username='weblogic',password='welcome1',url='t3://localhost:7001') except:   print "#########################################"   print "#   Unable to connect to Admin Server   #"   print "# Attempting to connect to Node Manager #"   print "#########################################"   nmConnect(domainName=os.getenv("DOMAIN_NAME")) print "#######################" print "# Stopping BAM Server #" print "#######################" shutdown('bam_server1') print "#######################" print "# Stopping SOA Server #" print "#######################" shutdown('soa_server1') print "#########################" print "# Stopping Admin Server #" print "#########################" shutdown('AdminServer') disconnect() nmDisconnect() EOF Stopping the Node Manager I stopped the node manager by searching for the java node manager process using the ps command and then killing that process. echo "#########################" echo "# Stopping Node Manager #" echo "#########################" kill -9 `ps -ef | grep java | grep NodeManager |  awk '{print $2;}'` echo "#####################" echo "# SOA Suite Stopped #" echo "#####################" read -p "Hit <enter> to continue" Stopping the Database Again my script for shutting down the database is the reverse of my start script.  It is available here.  The only change needed might be to the database name. #!/bin/sh echo "##############################" echo "# Setting Oracle Environment #" echo "##############################" . oraenv <<-EOF orcl EOF echo "######################" echo "# Stopping dbConsole #" echo "######################" emctl stop dbconsole echo "#####################" echo "# Stopping Listener #" echo "#####################" lsnrctl stop echo "#####################" echo "# Stopping Database #" echo "#####################" sqlplus / as sysdba <<-EOF shutdown immediate exit EOF read -p "Hit <enter> to continue" Cleaning Up Cleaning SOA Suite I often run tests and want to clean up all the log files.  The following script (available here) does this for the WebLogic servers in a given domain on a machine.  After setting the domain I just remove all files under the servers logs directories.  It also cleans up the log files I created with my startup scripts.  These scripts could be enhanced to copy off the log files if you needed them but in my test environments I don’t need them and would prefer to reclaim the disk space. #!/bin/sh echo "###########################" echo "# Setting SOA Environment #" echo "###########################" export MW_HOME=~oracle/Middleware11gPS1 export WL_HOME=$MW_HOME/wlserver_10.3 export ORACLE_HOME=$MW_HOME/Oracle_SOA export DOMAIN_NAME=soa_std_domain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME echo "##########################" echo "# Cleaning SOA Log Files #" echo "##########################" cd $DOMAIN_HOME rm -Rf logs/* servers/*/logs/* read -p "Hit <enter> to continue" Cleaning Database I also created a script to clean up the dump files of an Oracle database instance and also the EM log files (available here).  This relies on the machine name being correct as the EM log files are stored in a directory that is based on the hostname and the Oracle SID. #!/bin/sh echo "##############################" echo "# Setting Oracle Environment #" echo "##############################" . oraenv <<-EOF orcl EOF echo "#############################" echo "# Cleaning Oracle Log Files #" echo "#############################" rm -Rf $ORACLE_BASE/admin/$ORACLE_SID/*dump/* rm -Rf $ORACLE_HOME/`hostname`_$ORACLE_SID/sysman/log/* read -p "Hit <enter> to continue" Summary Hope you find the above scripts useful.  They certainly stop me hanging around waiting for things to happen on my test machine and make it easy to run a test, change parameters, bounce the SOA Suite and clean the logs between runs so I can see exactly what is happening. Now I need to get that mower started…

  • Begin the Clone Wars Have!

    - by Antony Reynolds
    Creating a New Virtual Machine from an Existing Virtual Disk In previous posts I described how I set up an OEL6 machine under VirtualBox that can run an 11gR2 database and FMW 11.1.1.5.  That is great if you want the DB and FMW running in the same virtual image and it has served me well for some proof of concepts and also for some testing of different JVMs.  However I also wanted to run some testing of FMW with the database running on a separate physical machine.  So in this post I will show how to take a VirtualBox image and create a new image based on the disks from that original image. What are my Options? There is more than one way to skin a cat, or in this case to create two separate VMs that can run on different hardware.  Some of the options include: Create new virtual disk images for each new VM. Clone the existing disk images and point the new VM at the cloned images. Point the new VM at the existing snapshots. #1 is too much like hard work, install OEL twice, install a database again, install FMW again, run RCU again!  Life is too short! #2 is probably the safest way of doing things.  VirtualBox allows you to clone a disk image for use in a separate machine.  However this of course duplicates the disk and means that it is now occupying 3 times the space, once for the original disk and twice more for the two clones I would need. #3 is the most space efficient way of doing things.  It does mean however that I can only run the new “cloned” images if I have access to the original image because that is where the base snapshots reside.  However this is not a problem for me as long as I remember to keep all threee images together.  So this is the approach we will follow. Snapshot, What Snapshot? As we are going to create new virtual machines based on existing snapshots we need to figure out which snapshot to use.  We do this by opening the “Media Manager” from within VirtualBox and moving the mouse over the snapshot images until we find the snapshots we want – the snapshot name is identified in the “Attached to:” comment.  In my case I wanted the FMW installed snapshot because that had a database configured for FMW alongside the FMW software.  I made a note of the filename of that snapshot (actually I just noted the first 5 characters as that was all that was needed to uniquely identify the snapshot file). When we create the new machines we will point them at the snapshot filename we have just checked. Network or NotWork? Because we want the two new machines to communicate with each other when hosted in different physical machines we can’t use the default NAT networking mode without a lot of hassle.  But at the same time we need them to have fixed IP addresses relative to each other so that they can see each other whilst also being able to see the outside world. To achieve all these requirements I created two network adapters for each machine.  Adapter 1 was a standard NAT mapping.  This will allow each machine to get a dynamic IP address (10.0.2.15 by default) that can be used to access the external world through the VBox provided NAT gateway.  This is the same as the existing configuration. The second adapter I created as a bridged adapter.  This gives the virtual machine direct access to the host network card and by using fixed IP addresses each machine can see the other.  It is important to choose fixed IP addresses that are not routable across your internal network so you don’t get any clashes with other machines on your network.  Of course you could always get proper fixed IP addresses from your network people, but I have serveral people using my images and as long as I don’t have two instances of the same VM on the same network segment this is easier and avoids reconfiguring the network every time someone wants a copy of my VM.  If it is available I would suggest using the 10.0.3.* network as 10.0.2.* is the default NAT network.  You can check availability by pinging 10.0.3.1 and 10.0.3.2 from your host machine.  If it times out then you are probably safe to use that. Creating the New VMs Now that I had collected the data that I needed I went ahead and created the new VMs. When asked for a “Boot Hard Disk” I used the “Choose a virtual hard disk file…” link to find the snapshot I had previously selected and set that to be the existing hard disk.  I chose the previously existing SOA 11.1.1.5 install for both the new DB and FMW machines because that snapshot had the database with the RCU completed that I wanted for my DB machine and it had the SOA software installed which I wanted for my FMW machine. After the initial creation of the virtual machine go into the network setting section and enable a second adapter which will be bridged.  Make a note of the MAC addresses (the last four digits should be sufficient) of the two adapters so that you can later set the bridged adapter to use fixed IP and the NAT adapter to use DHCP. We are now ready to start the VMs and reconfigure Linux. Reconfiguring Linux Because I now have two new machines I need to change their network configuration.  In particular I need to change the hostname, update the hosts file and change the network settings. Changing the Hostname I renamed both hosts by running the hostname command as root: hostname vboxfmw.oracle.com I also edited the /etc/sysconfig file and set the correct hostname in there. HOSTNAME=vboxfmw.oracle.com Changing the Network Settings I needed to change the network configuration to give the bridged network a fixed IP address.  I first explicitly set the MAC addresses of the two adapters, because the order of the virtual adapters in the VirtualBox Manager is not necessarily the same as the order of the adapters in the guest OS.  So I went in to the System->Preferences->Network Connections screen and explicitly set the “Device MAC address” for the two adapters. Having correctly mapped the Linux adapters to the VirtualBox adapters I then set the Bridged adapter to use fixed IP addressing rather than DHCP.  There is no need for additional routing or default gateways because we expect the two machine to be on the same LAN segment. Updating the Hosts File Having renamed the machines and reconfigured the network I then updated the /etc/hosts file to refer to the new machine name add a new line to the hosts file to provide an additional IP address for my server (the new fixed IP address) add a new line for the fixed IP address of the other virtual machine 10.0.3.101      vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.2.15       vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.3.102      vboxfmw.oracle.com      vboxfmw # Added by NetworkManager 127.0.0.1       localhost.localdomain   localhost ::1     vboxdb.oracle.com       vboxdb  localhost6.localdomain6 localhost6 To make sure everything takes effect I restarted the server. Reconfiguring the Database on the DB Machine Because we changed the hostname the listener and the EM console no longer start so I need to modify the listener.ora to use the new hostname and I also need to rebuild the EM configuration because it also relies on the hostname. I edited the $ORACLE_HOME/network/admin/listener.ora and changed the listening address to the new hostname:       (ADDRESS = (PROTOCOL = TCP)(HOST = vboxdb.oracle.com)(PORT = 1521)) After changing the listener.ora I was able to start the listener using: lsnrctl start I also had to reconfigure the EM database control.  I first deconfigured it using the command: emca -deconfig dbcontrol db -repos drop This drops the repository and removes any existing registered dbcontrols. I then re-configured it using the following command: emca -config dbcontrol db -repos create This creates the EM repository and then configures and starts dbcontrol. Now my database machine is ready so I can close it down and take a snapshot. Disabling the Database on the FMW Machine I set up the database to start automatically by creating a service called “dbora”.  On the FMW machine I do not need the database running so I can prevent it auto-starting by running the following command: chkconfig –del dbora Note that because I am using a snapshot it is not a waste of disk space to have the DB installed but not used.  As long as I don’t run it, it won’t cost me anything. I can now close the FMW machine down and take a snapshot. Creating a New Domain The FMW machine is now ready to create a new domain.  When creating the domain I can point it at the second machine which is running the database.  I can potentially run these machines on two separate physical machines as long as I have the original virtual machine available to both of the physical machines. Gotchas in Snapshotting VirtualBox does not support the concept of linked machines in a network like some virtualization technologies so when creating a snapshot it is a good idea to shut both VMs down and then take a snapshot on both of them.  This is because we want to keep the database in sync with the middleware.  One way to make sure that this happens would be to place all the domain configuration files on the database server via an NFS share, this would mean that all we would need to snapshot would be the database machine because that would hold all the state and configuration. The Sky’s the Limit We have covered a simple case of having just two machines.  I have a more complicated configuration in which two machine run a RAC database off the same base OS image, and two more machines run a SOA cluster based on the same OS image.  Just remember what machine holds state and what are the consequences of taking a snapshot.
