• SPARC T4-2 Produces World Record Oracle Essbase Aggregate Storage Benchmark Result

  - by Brian

  Significance of Results Oracle's SPARC T4-2 server configured with a Sun Storage F5100 Flash Array and running Oracle Solaris 10 with Oracle Database 11g has achieved exceptional performance for the Oracle Essbase Aggregate Storage Option benchmark. The benchmark has upwards of 1 billion records, 15 dimensions and millions of members. Oracle Essbase is a multi-dimensional online analytical processing (OLAP) server and is well-suited to work well with SPARC T4 servers. The SPARC T4-2 server (2 cpus) running Oracle Essbase 11.1.2.2.100 outperformed the previous published results on Oracle's SPARC Enterprise M5000 server (4 cpus) with Oracle Essbase 11.1.1.3 on Oracle Solaris 10 by 80%, 32% and 2x performance improvement on Data Loading, Default Aggregation and Usage Based Aggregation, respectively. The SPARC T4-2 server with Sun Storage F5100 Flash Array and Oracle Essbase running on Oracle Solaris 10 achieves sub-second query response times for 20,000 users in a 15 dimension database. The SPARC T4-2 server configured with Oracle Essbase was able to aggregate and store values in the database for a 15 dimension cube in 398 minutes with 16 threads and in 484 minutes with 8 threads. The Sun Storage F5100 Flash Array provides more than a 20% improvement out-of-the-box compared to a mid-size fiber channel disk array for default aggregation and user-based aggregation. The Sun Storage F5100 Flash Array with Oracle Essbase provides the best combination for large Oracle Essbase databases leveraging Oracle Solaris ZFS and taking advantage of high bandwidth for faster load and aggregation. Oracle Fusion Middleware provides a family of complete, integrated, hot pluggable and best-of-breed products known for enabling enterprise customers to create and run agile and intelligent business applications. Oracle Essbase's performance demonstrates why so many customers rely on Oracle Fusion Middleware as their foundation for innovation.

Typical administrative and end-user operations for OLAP applications were simulated to produce benchmark results. The benchmark test results include: Database Load: Time elapsed to build a database including outline and data load. Default Aggregation: Time elapsed to build aggregation. User Based Aggregation: Time elapsed of the aggregate views proposed as a result of tracked retrieval queries. Summary of the data used for this benchmark: 40 flat files, each of size 1.2 GB, 49.4 GB in total 10 million rows per file, 1 billion rows total 28 columns of data per row Database outline has 15 dimensions (five of them are attribute dimensions) Customer dimension has 13.3 million members 3 rule files Key Points and Best Practices The Sun Storage F5100 Flash Array has been used to accelerate the application performance. Setting data load threads (DLTHREADSPREPARE) to 64 and Load Buffer to 6 improved dataloading by about 9%. Factors influencing aggregation materialization performance are "Aggregate Storage Cache" and "Number of Threads" (CALCPARALLEL) for parallel view materialization. The optimal values for this workload on the SPARC T4-2 server were: Aggregate Storage Cache: 32 GB CALCPARALLEL: 16   See Also Oracle Essbase Aggregate Storage Option Benchmark on Oracle's SPARC T4-2 Server oracle.com Oracle Essbase oracle.com OTN SPARC T4-2 Server oracle.com OTN Oracle Solaris oracle.com OTN Oracle Database 11g Release 2 Enterprise Edition oracle.com OTN Disclosure Statement Copyright 2012, Oracle and/or its affiliates.

• Uninstall, Disable, or Remove Windows 7 Media Center

  - by Mysticgeek

  Although Windows 7 Media Center has improved a lot over previous versions of Windows, but you might want to disable it for different reasons. Here we take a look at a couple of methods to get rid of it. There are a variety of reasons you might want to disable Windows 7 Media Center. Maybe you own a business and don’t want it to run on the machines. Or perhaps you don’t use it at all and just don’t want it around. Turn Off WMC Using Programs and Features Probably the easiest way to get rid of it on all versions of Windows 7 is to open Control Panel and select Programs and Features. This method is similar to disabling Internet Explorer 8 in Windows 7. On the left hand panel click on Turn Windows Features on or off. Scroll down to Media Features and expand the folder. Then Uncheck Windows Media Center… You’ll get a verification message making sure you want to disable it, click Yes. Then the box next to Windows Media Center will be empty…click OK. Wait while WMC is disabled… To complete the process a reboot is required. After getting back from the restart, the WMC icon will be gone and there won’t be any way to launch it. Re-enable WMC If you want to re-enable it, just go back in and recheck it. Again you’ll need to wait while it’s configured, but when it’s done, a restart is not required.   Disable Media Center Using Group Policy Note: This process uses Group Policy Editor which is not available in Home versions of Windows 7. Click on the Start menu and type gpedit.msc into the Search box and hit Enter. Now navigate to User Configuration \ Administrative Templates \ Windows Components \ Windows Media Center. Double-click on Do not allow Windows Media Center to run. Then select the radio button next to Enabled, click OK and close out of Group Policy Editor. Now if a user tries to launch WMC they will get the following message. Conclusion If you’re not a fan of Windows Media Center or want to disable it for whatever reason, the process is simple and there are a couple of ways you can do it. WMC is not included in Starter or Home Basic versions of Windows 7. If you’re new to Windows 7 Media Center, you might want to check out our guide on getting started and setting up live TV.

• SSIS - Connect to Oracle on a 64-bit machine (Updated for SSIS 2008 R2)

  - by jorg

  We recently had a few customers where a connection to Oracle on a 64 bit machine was necessary. A quick search on the internet showed that this could be a big problem. I found all kind of blog and forum posts of developers complaining about this. A lot of developers will recognize the following error message: Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. After a lot of searching, trying and debugging I think I found the right way to do it! Problems Because BIDS is a 32 bit application, as well on 32 as on 64 bit machines, it cannot see the 64 bit driver for Oracle. Because of this, connecting to Oracle from BIDS on a 64 bit machine will never work when you install the 64 bit Oracle client. Another problem is the "Microsoft Provider for Oracle", this driver only exists in a 32 bit version and Microsoft has no plans to create a 64 bit one in the near future. The last problem I know of is in the Oracle client itself, it seems that a connection will never work with the instant client, so always use the full client. There are also a lot of problems with the 10G client, one of it is the fact that this driver can't handle the "(x86)" in the path of SQL Server. So using the 10G client is no option! Solution Download the Oracle 11G full client. Install the 32 AND the 64 bit version of the 11G full client (Installation Type: Administrator) and reboot the server afterwards. The 32 bit version is needed for development from BIDS with is 32 bit, the 64 bit version is needed for production with the SQLAgent, which is 64 bit. Configure the Oracle clients (both 32 and 64 bits) by editing  the files tnsnames.ora and sqlnet.ora. Try to do this with an Oracle DBA or, even better, let him/her do this. Use the "Oracle provider for OLE DB" from SSIS, don't use the "Microsoft Provider for Oracle" because a 64 bit version of it does not exist. Schedule your packages with the SQLAgent. Background information Visual Studio (BI Dev Studio)is a 32bit application. SQL Server Management Studio is a 32bit application. dtexecui.exe is a 32bit application. dtexec.exe has both 32bit and 64bit versions. There are x64 and x86 versions of the Oracle provider available. SQLAgent is a 64bit process. My advice to BI consultants is to get an Oracle DBA or professional for the installation and configuration of the 2 full clients (32 and 64 bit). Tell the DBA to download the biggest client available, this way you are sure that they pick the right one ;-) Testing if the clients have been installed and configured in the right way can be done with Windows ODBC Data Source Administrator: Start... Programs... Administrative tools... Data Sources (ODBC) ADITIONAL STEPS FOR SSIS 2008 R2 It seems that, unfortunately, some additional steps are necessary for SQL Server 2008 R2 installations: 1. Open REGEDIT (Start… Run… REGEDIT) on the server and search for the following entry (for the 32 bits driver): HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI Make sure the following values are entered: 2. Next, search for (for the 64 bits driver): HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI Make sure the same values as above are entered. 3. Reboot your server.

• My Tech Ed North America Preview - Certification Edition

  - by Chris Gardner

  In my previous TechEd North America Preview, I addressed all the content I wanted to see at the show. This time, we shall turn our attention to the certifications I might try to pick up. If you have never been to TechEd North America before, one of the greatest things about the event is an on-site certification center. If you have a couple hours to spare, you can walk up to a test. The first test on my agenda is 70-5231. I took this update test once, but did not do well on the MVC portion2. A few practice tests later, and I think I'm ready to fake that section. After that, I need to complete my road to being a master. The good folks here at work have been having a real love / hate relationship with the idea of me become an MCM in SQL Server3. Of course, before I do that, I need to finally take the SQL Administration tests. Thus, we shall add 70-4324 and 70-4505 to the list. Speaking of MCM, TechEd North America will have a special on test 88-9706. This test is normally $500, and you have to find a place to take it7. However, there is a special 50% off rate for people who take it on location. With those kind of prices, I may just take it as a form of study guide. As a final push, I may take some Windows Phone exams. I mentioned in my previous post that I may attend the 70-5998 Exam Cram session. Unfortunately, I will be staffing the Hands-On-Lab at that time. As we know, this has never stopped me from taking a test. This may lead to fits of 70-5069, but after we've come this far... That should complete my list. Do I really think I'll find time to take 6 tests at TechEd North America? Probably not. I have done it at TechEd North America before, but that was before I was TechEd North America staff. I also had a co-worker pass 9 in one year, but he basically did nothing but travel to Orlando in 2007 to take tests. And what's the point of attending a HUGE conference if you don't network? Of course, networking will have to wait for Friday's post... 1 Upgrade: Transition Your MCPD .NET Framework 3.5 Web Developer Skills to MCPD .NET Framework 4 Web Developer 2Because I never have used, nor do I really think I ever will use, MVC... 3By that, I mean they love the idea, and they hate the price 4Microsoft SQL Server 2008, Implementation and Maintenance 5PRO: Designing, Optimizing and Maintaining a Database Administrative Solution Using Microsoft SQL Server 2008 6SQL Server 2008 Microsoft Certified Master: Knowledge Exam 7Which isn't nearly as expensive as the Lab Exam, nor as difficult to find a location.

• Some OBI EE Tricks and Tips in the Admin Tool By Gerry Langton

  - by hamsun

  How to set the log level from a Session variable Initialization block As we know it is normal to set the log level non-zero for a particular user when we wish to debug problems. However sometimes it is inconvenient to go into each user’s properties in the Admin tool and update the log level. So I am showing a method which allows the log level to be set for all users via a session initialization block. This is particularly useful for anyone wanting an alternative way to set the log level. The screen shots shown are using the OBIEE 11g SampleApp demo but are applicable to any environment. Open the appropriate rpd in on-line mode and navigate to Manage Variables. Select Session Initialization Blocks, right click in the white space and create a New Initialization Block. I called the Initialization block Set_Loglevel . Now click on ‘Edit Data Source’ to enter the SQL. Chose the ‘Use OBI EE Server’ option for the SQL. This means that the SQL provided must use tables which have been defined in the Physical layer of the RPD, and whilst there is no need to provide a connection pool you must work in On-Line mode. The SQL can access any of the RPD tables and is purely used to return a value of 2. The ‘Test’ button confirms that the SQL is valid. Next, click on the ‘Edit Data Target’ button to add the LOGLEVEL variable to the initialization block. Check the ‘Enable any user to set the value’ option so that this will work for any user. Click OK and the following message will display as LOGLEVEL is a system session variable: Click ‘Yes’. Click ‘OK’ to save the Initialization block. Then check in the On-LIne changes. To test that LOGLEVEL has been set, log in to OBIEE using an administrative login (e.g. weblogic) and reload server metadata, either from the Analysis editor or from Administration > Reload Files and Metadata link. Run a query then navigate to Administration > Manage Sessions and click ‘View Log’ for the query just issued (which should be approximately the last in the list). A log file should exist and with LOGLEVEL set to 2 should include both logical and physical sql. If more diagnostic information is required then set LOGLEVEL to a higher value. If logging is required only for a particular analysis then an alternative method can be used directly from the Analysis editor. Edit the analysis for which debugging is required and click on the Advanced tab. Scroll down to the Advanced SQL clauses section and enter the following in the Prefix box: SET VARIABLE LOGLEVEL = 2; Click the ‘Apply SQL’ button. The SET VARIABLE statement will now prefix the Analysis’s logical SQL. So that any time this analysis is run it will produce a log.

• Tuning Default WorkManager - Advantages and Disadvantages

  - by Murali Veligeti

  Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

• Create a Remote Git Repository from an Existing XCode Repository

  - by codeWithoutFear

  Introduction Distributed version control systems (VCS’s), like Git, provide a rich set of features for managing source code.  Many development tools, including XCode, provide built-in support for various VCS’s.  These tools provide simple configuration with limited customization to get you up and running quickly while still providing the safety net of basic version control. I hate losing (and re-doing) work.  I have OCD when it comes to saving and versioning source code.  Save early, save often, and commit to the VCS often.  I also hate merging code.  Smaller and more frequent commits enable me to minimize merge time and effort as well. The work flow I prefer even for personal exploratory projects is: Make small local changes to the codebase to create an incrementally improved (and working) system. Commit these changes to the local repository.  Local repositories are quick to access, function even while offline, and provides the confidence to continue making bold changes to the system.  After all, I can easily recover to a recent working state. Repeat 1 & 2 until the codebase contains “significant” functionality and I have connectivity to the remote repository. Push the accumulated changes to the remote repository.  The smaller the change set, the less likely extensive merging will be required.  Smaller is better, IMHO. The remote repository typically has a greater degree of fault tolerance and active management dedicated to it.  This can be as simple as a network share that is backed up nightly or as complex as dedicated hardware with specialized server-side processing and significant administrative monitoring. XCode’s out-of-the-box Git integration enables steps 1 and 2 above.  Time Machine backups of the local repository add an additional degree of fault tolerance, but do not support collaboration or take advantage of managed infrastructure such as on-premises or cloud-based storage. Creating a Remote Repository These are the steps I use to enable the full workflow identified above.  For simplicity the “remote” repository is created on the local file system.  This location could easily be on a mounted network volume. Create a Test Project My project is called HelloGit and is located at /Users/Don/Dev/HelloGit.  Be sure to commit all outstanding changes.  XCode always leaves a single changed file for me after the project is created and the initial commit is submitted. Clone the Local Repository We want to clone the XCode-created Git repository to the location where the remote repository will reside.  In this case it will be /Users/Don/Dev/RemoteHelloGit. Open the Terminal application. Clone the local repository to the remote repository location: git clone /Users/Don/Dev/HelloGit /Users/Don/Dev/RemoteHelloGit Convert the Remote Repository to a Bare Repository The remote repository only needs to contain the Git database.  It does not need a checked out branch or local files. Go to the remote repository folder: cd /Users/Don/Dev/RemoteHelloGit Indicate the repository is “bare”: git config --bool core.bare true Remove files, leaving the .git folder: rm -R * Remove the “origin” remote: git remote rm origin Configure the Local Repository The local repository should reference the remote repository.  The remote name “origin” is used by convention to indicate the originating repository.  This is set automatically when a repository is cloned.  We will use the “origin” name here to reflect that relationship. Go to the local repository folder: cd /Users/Don/Dev/HelloGit Add the remote: git remote add origin /Users/Don/Dev/RemoteHelloGit Test Connectivity Any changes made to the local Git repository can be pushed to the remote repository subject to the merging rules Git enforces. Create a new local file: date > date.txt /li> Add the new file to the local index: git add date.txt Commit the change to the local repository: git commit -m "New file: date.txt" Push the change to the remote repository: git push origin master Now you can save, commit, and push/pull to your OCD hearts’ content! Code without fear! --Don

• Protecting Consolidated Data on Engineered Systems

  - by Steve Enevold

  In this time of reduced budgets and cost cutting measures in Federal, State and Local governments, the requirement to provide services continues to grow. Many agencies are looking at consolidating their infrastructure to reduce cost and meet budget goals. Oracle's engineered systems are ideal platforms for accomplishing these goals. These systems provide unparalleled performance that is ideal for running applications and databases that traditionally run on separate dedicated environments. However, putting multiple critical applications and databases in a single architecture makes security more critical. You are putting a concentrated set of sensitive data on a single system, making it a more tempting target.  The environments were previously separated by iron so now you need to provide assurance that one group, department, or application's information is not visible to other personnel or applications resident in the Exadata system. Administration of the environments requires formal separation of duties so an administrator of one application environment cannot view or negatively impact others. Also, these systems need to be in protected environments just like other critical production servers. They should be in a data center protected by physical controls, network firewalls, intrusion detection and prevention, etc Exadata also provides unique security benefits, including a reducing attack surface by minimizing packages and services to only those required. In addition to reducing the possible system areas someone may attempt to infiltrate, Exadata has the following features: 1.    Infiniband, which functions as a secure private backplane 2.    IPTables  to perform stateful packet inspection for all nodes               Cellwall implements firewall services on each cell using IPTables 3.    Hardware accelerated encryption for data at rest on storage cells Oracle is uniquely positioned to provide the security necessary for implementing Exadata because security has been a core focus since the company's beginning. In addition to the security capabilities inherent in Exadata, Oracle security products are all certified to run in an Exadata environment. Database Vault Oracle Database Vault helps organizations increase the security of existing applications and address regulatory mandates that call for separation-of-duties, least privilege and other preventive controls to ensure data integrity and data privacy. Oracle Database Vault proactively protects application data stored in the Oracle database from being accessed by privileged database users. A unique feature of Database Vault is the ability to segregate administrative tasks including when a command can be executed, or that the DBA can manage the health of the database and objects, but may not see the data Advanced Security  helps organizations comply with privacy and regulatory mandates by transparently encrypting all application data or specific sensitive columns, such as credit cards, social security numbers, or personally identifiable information (PII). By encrypting data at rest and whenever it leaves the database over the network or via backups, Oracle Advanced Security provides the most cost-effective solution for comprehensive data protection. Label Security  is a powerful and easy-to-use tool for classifying data and mediating access to data based on its classification. Designed to meet public-sector requirements for multi-level security and mandatory access control, Oracle Label Security provides a flexible framework that both government and commercial entities worldwide can use to manage access to data on a "need to know" basis in order to protect data privacy and achieve regulatory compliance  Data Masking reduces the threat of someone in the development org taking data that has been copied from production to the development environment for testing, upgrades, etc by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with IT developers or offshore business partners  Audit Vault and Database Firewall Oracle Audit Vault and Database Firewall serves as a critical detective and preventive control across multiple operating systems and database platforms to protect against the abuse of legitimate access to databases responsible for almost all data breaches and cyber attacks.  Consolidation, cost-savings, and performance can now be achieved without sacrificing security. The combination of built in protection and Oracle’s industry-leading data protection solutions make Exadata an ideal platform for Federal, State, and local governments and agencies.

• Best Practices - Core allocation

  - by jsavit

  This post is one of a series of "best practices" notes for Oracle VM Server for SPARC (also called Logical Domains) Introduction SPARC T-series servers currently have up to 4 CPU sockets, each of which has up to 8 or (on SPARC T3) 16 CPU cores, while each CPU core has 8 threads, for a maximum of 512 dispatchable CPUs. The defining feature of Oracle VM Server for SPARC is that each domain is assigned CPU threads or cores for its exclusive use. This avoids the overhead of software-based time-slicing and emulation (or binary rewriting) of system state-changing privileged instructions used in traditional hypervisors. To create a domain, administrators specify either the number of CPU threads or cores that the domain will own, as well as its memory and I/O resources. When CPU resources are assigned at the individual thread level, the logical domains constraint manager attempts to assign threads from the same cores to a domain, and avoid "split core" situations where the same CPU core is used by multiple domains. Sometimes this is unavoidable, especially when domains are allocated and deallocated CPUs in small increments. Why split cores can matter Split core allocations can silenty reduce performance because multiple domains with different address spaces and memory contents are sharing the core's Level 1 cache (L1$). This is called false cache sharing since even identical memory addresses from different domains must point to different locations in RAM. The effect of this is increased contention for the cache, and higher memory latency for each domain using that core. The degree of performance impact can be widely variable. For applications with very small memory working sets, and with I/O bound or low-CPU utilization workloads, it may not matter at all: all machines wait for work at the same speed. If the domains have substantial workloads, or are critical to performance then this can have an important impact: This blog entry was inspired by a customer issue in which one CPU core was split among 3 domains, one of which was the control and service domain. The reported problem was increased I/O latency in guest domains, but the root cause might be higher latency servicing the I/O requests due to the control domain being slowed down. What to do about it Split core situations are easily avoided. In most cases the logical domain constraint manager will avoid it without any administrative action, but it can be entirely prevented by doing one of the several actions: Assign virtual CPUs in multiples of 8 - the number of threads per core. For example: ldm set-vcpu 8 mydomain or ldm add-vcpu 24 mydomain. Each domain will then be allocated on a core boundary. Use the whole core constraint when assigning CPU resources. This allocates CPUs in increments of entire cores instead of virtual CPU threads. The equivalent of the above commands would be ldm set-core 1 mydomain or ldm add-core 3 mydomain. Older syntax does the same thing by adding the -c flag to the add-vcpu, rm-vcpu and set-vcpu commands, but the new syntax is recommended. When whole core allocation is used an attempt to add cores to a domain fails if there aren't enough completely empty cores to satisfy the request. See https://blogs.oracle.com/sharakan/entry/oracle_vm_server_for_sparc4 for an excellent article on this topic by Eric Sharakan. Don't obsess: - if the workloads have minimal CPU requirements and don't need anywhere near a full CPU core, then don't worry about it. If you have low utilization workloads being consolidated from older machines onto a current T-series, then there's no need to worry about this or to assign an entire core to domains that will never use that much capacity. In any case, make sure the most important domains have their own CPU cores, in particular the control domain and any I/O or service domain, and of course any important guests. Summary Split core CPU allocation to domains can potentially have an impact on performance, but the logical domains manager tends to prevent this situation, and it can be completely and simply avoided by allocating virtual CPUs on core boundaries.

• Friday Tips #3

  - by Chris Kawalek

  Even though yesterday was Thanksgiving here in the US, we still have a Friday tip for those of you around your computers today. In fact, we have two! The first one came in last week via our #AskOracleVirtualization Twitter hashtag. The tweet has disappeared into the ether now, but we remember the gist, so here it is: Question: Will there be an Oracle Virtual Desktop Client for Android? Answer by our desktop virtualization product development team: We are looking at Android as a supported platform for future releases. Question: How can I make a Sun Ray Client automatically connect to a virtual machine? Answer by Rick Butland, Principal Sales Consultant, Oracle Desktop Virtualization: Someone recently asked how they can assign VM’s to specific Sun Ray Desktop Units (“DTU’s”) without any user interfaction being required, without the “Desktop Selector” being displayed, or any User Directory.  That is, they wanted each Sun Ray to power on and immediately connect to a pre-assigned Solaris VM.   This can be achieved by using “tokens” for user assignment – that is, the tokens found on Smart Cards, DTU’s, or OVDC clients can be used in place of user credentials.  Note, however, that mixing “token-only” assignments and “User Directories” in the same VDI Center won’t work.   Much of this procedure is covered in the documentation, particularly here. But it can useful to have everything in one place, “cookbook-style”:  1. Create the “token-only” directory type: From the VDI administration interface, select:  “Settings”, “Company”, “New”, select the “None” radio button, and click “Next.” Enter a name for the new “Company”, and click “Next”, then “Finish.” 2. Create Desktop Providers, Pools, and VM’s as appropriate. 3. Access the Sun Ray administration interface at http://servername:1660 and login using “root” credentials, and access the token-id’s you wish to use for assignment.  If you’re using DTU tokens rather than Smart Card tokens, these can be found under the “Tokens” tab, and “Search-ing” using the “Currently Used Tokens” tab.  DTU’s can be identified by the prefix “psuedo.”   For example: 4. Copy/paste this token into the VDI administrative interface, by selecting “Users”, “New”, and pasting in the token ID, and click “OK” - for example: 5. Assign the token (DTU) to a desktop, that is, in the VDI Admin Gui, select “Pool”, “Desktop”, select the VM, and click "Assign" and select the token you want, for example: In addition to assigning tokens to desktops, you'll need to bypass the login screen.  To do this, you need to do two things:  1.  Disable VDI client authentication with:  /opt/SUNWvda/sbin/vda settings-setprops -p clientauthentication=Disabled 2. Disable the VDI login screen – to do this,  add a kiosk argument of "-n" to the Sun Ray kiosk arguments screen.   You set this on the Sun Ray administration page - "Advanced", "Kiosk Mode", "Edit", and add the “-n” option to the arguments screen, for example: 3.  Restart both the Sun Ray and VDI services: # /opt/SUNWut/sbin/utstart –c # /opt/SUNWvda/sbin/vda-service restart Remember, if you have a question for us, please post on Twitter with our hashtag (again, it's #AskOracleVirtualization), and we'll try to answer it if we can. See you next time!

• Taking HRMS to the Cloud to Simplify Human Resources Management

  - by HCM-Oracle

  By Anke Mogannam With human capital management (HCM) a top-of-mind issue for executives in every industry, human resources (HR) organizations are poised to have their day in the sun—proving not just their administrative worth but their strategic value as well.  To make good on that promise, however, HR must modernize. Indeed, if HR is to act as an agent of change—providing the swift reallocation of employees  and the rapid absorption of employee data required for enterprises to shift course on a dime—it must first deal with the disruptive change at its own front door. And increasingly, that means choosing the right technology and human resources management system (HRMS) for managing the entire employee lifecycle. Unfortunately, for most organizations, this task has proved easier said than done. This is because while much has been written about advances in HRMS technology, until recently, most of those advances took the form of disparate on-premises solutions designed to serve very specific purposes. Although this may have resulted in key competencies in certain areas, it also meant that processes for core HR functions like payroll and benefits were being carried out in separate systems from those used for talent management, workforce optimization, training, and so on. With no integration—and no single system of record—processes were disconnected, ease of use was impeded, user experience was diminished, and vital data was left untapped.  Today, however, that scenario has begun to change, and end-to-end cloud-based HCM solutions have moved from wished-for innovations to real-life solutions. Why, then, have HR organizations been so slow in adopting them? The answer—it would seem—is, “It’s complicated.” So complicated, in fact, that 45 percent of the respondents to PwC’s “Annual HR Technology Survey” (for 2013) reported having no formal HR software roadmap, and 40 percent stated that they “did not know” whether their organizations would be increasing their use of cloud or software as a service (SaaS) for HR.  Clearly, HR organizations need help sorting through the morass of HR software options confronting them. But just as clearly, there’s an enormous opportunity awaiting those that do. The trick will come in charting a course that allows HR to leverage existing technology while investing in the cloud-based solutions that will deliver the end-to-end processes, easy-to-understand analytics, and superior adaptability required to simplify—and add value to—every aspect of employee management. The Opportunity therefore is to cut costs, drive Innovation, and increase engagement by moving to cloud-based HCM.  Then you will benefit from one Interface, leverage many access points, and  gain at-a-glance insight across your entire workforce. With many legacy on-premises HR systems not being efficient anymore and cloud-based, integrated systems that span the range of HR functions finally reaching maturity, the time is ripe for moving core HR to the cloud. Indeed, for the first time ever there are more HRMS replacement initiatives than HRMS upgrade initiatives under way, and the majority of them involve moving to the cloud per Cedar Crestone’s 2013-2014 HRMS survey. To learn how you can launch your own cloud HCM initiative and begin using HR to power the enterprise, visit Oracle HRMS in the Cloud and Oracle’s new customer 2 cloud program.

• Four Easy Ways to Save a Rocky CRM Relationship

  - by Divya Malik

   Today, I am pleased to introduce our guest blogger Luke Christianson. Luke is  an Application Sales rep based out of Minneapolis, MN.  You can find him on LinkedIn and follow him on Twitter. In any relationship, sooner or later, the excitement fades away.  The honeymoon period gives way to the old routines you had, before you committed to each other and you eventually begin doing things apart from one another.  I’m not talking about a marriage…  Well, I guess I am.Commitment to a CRM tool and building a deep and lasting relationship is not much different than the basics of a traditional love story.  After your controlled CRM pilot program, and maybe the National Sales Meeting where you couldn’t escape those three wonderful letters, CRM, you will soon find that if you haven’t designed an environment where it’s going to enable your reps to make more money, the relationship is doomed.   . If you’re currently in a dysfunctional CRM relationship, here are 4 simple tips to re-engaging users and getting that spark back. Shadow a Sales Rep:   Chances are you can find out exactly what is preventing your sales reps from using the application by simply watching how they go about their day.  Sales reps are driven by money, not by additional administrative duties.  Your system needs to be setup so that they can get the information they need quickly, facilitate making key updates and run their business out of one easy-to-use application.  Increase your sales team’s productivity by 5% automatically:    Cancel the weekly forecast calls with your reps and require them update their opportunities in CRM.  Something else that I’ve seen work extremely well, is when you do Monthly or Quarterly reviews, do not let your sales reps bring anything into the room with them; no spreadsheets, notebooks, or computers.  Everything they need to tell you should be able to be put into CRM and fully accessible by the Sales Manager at any time.  Tool time:      Make sure the tools that you have selected meet both your short-term goals and your long term goals.   You need tools that can adapt like your business does.  You probably can’t wait two months for an update to a picklist value or for the addition of a simple workflow rule.  Do you feel the tools that are in place can create the experience you want for your users? and finally, if all else fails... Keep It Simple, Stupid:     Do you really need to require 15 fields to create an Opportunity?  Do you need to clutter the interface with different reports that don’t add daily value?  Most CRM systems on the market today are flexible enough today that your admin could clean up most of the unnecessary interface ‘noise’ in a few hours.  If they're not, see #3. Every strong relationship can be tedious at times, you’ll fight and eventually make amends, you may even threaten to upgrade to a newer model…  But be patient and think about what you want to achieve and you’ll find a partner for life.

• CI tests to enforce specific development rules - good practice?

  - by KeithS

  The following is all purely hypothetical and any particular portion of it may or may not accurately describe real persons or situations, whether living, dead or just pretending. Let's say I'm a senior dev or architect in charge of a dev team working on a project. This project includes a security library for user authentication/authorization of the application under development. The library must be available for developers to edit; however, I wish to "trust but verify" that coders are not doing things that could compromise the security of the finished system, and because this isn't my only responsibility I want it to be done in an automated way. As one example, let's say I have an interface that represents a user which has been authenticated by the system's security library. The interface exposes basic user info and a list of things the user is authorized to do (so that the client app doesn't have to keep asking the server "can I do this?"), all in an immutable fashion of course. There is only one implementation of this interface in production code, and for the purposes of this post we can say that all appropriate measures have been taken to ensure that this implementation can only be used by the one part of our code that needs to be able to create concretions of the interface. The coders have been instructed that this interface and its implementation are sacrosanct and any changes must go through me. However, those are just words; the security library's source is open for editing by necessity. Any of my devs could decide that this secured, private, hash-checked implementation needs to be public so that they could do X, or alternately they could create their own implementation of this public interface in a different library, exposing the hashing algorithm that provides the secure checksum, in order to do Y. I may not be made aware of these changes so that I can beat the developer over the head for it. An attacker could then find these little nuggets in an unobfuscated library of the compiled product, and exploit it to provide fake users and/or falsely-elevated administrative permissions, bypassing the entire security system. This possibility keeps me awake for a couple of nights, and then I create an automated test that reflectively checks the codebase for types deriving from the interface, and fails if it finds any that are not exactly what and where I expect them to be. I compile this test into a project under a separate folder of the VCS that only I have rights to commit to, have CI compile it as an external library of the main project, and set it up to run as part of the CI test suite for user commits. Now, I have an automated test under my complete control that will tell me (and everyone else) if the number of implementations increases without my involvement, or an implementation that I did know about has anything new added or has its modifiers or those of its members changed. I can then investigate further, and regain the opportunity to beat developers over the head as necessary. Is this considered "reasonable" to want to do in situations like this? Am I going to be seen in a negative light for going behind my devs' backs to ensure they aren't doing something they shouldn't?

• Application Logging needs work

  Application Logging Application logging is the act of logging events that occur within an application much like how a court report documents what happens in court case. Application logs can be useful for several reasons, but the most common use for logs is to recreate steps to find the root cause of applications errors. Other uses can include the detection of Fraud, verification of user activity, or provide audits on user/data interactions. “Logs can contain different kinds of data. The selection of the data used is normally affected by the motivation leading to the logging. “ (OWASP, 2009) OWASP also stats that logging include applicable debugging information like the event date time, responsible process, and a description of the event. “There are many reasons why a logging system is a necessary part of delivering a distributed application. One of the most important is the ability to track exactly how many users are using the application during different time periods.” (Hatton, 2000) Hatton also states that application logging helps system designers determine whether parts of an application aren't being used as designed. He implies that low usage can be used to identify if users like or do not like aspects of a system based on user usage of the application. This enables application designers to extract why users don't like aspects of an application so that changes can be made to increase its usefulness and effectiveness. “Logging memory usage can also assist you in tuning up the internals of your application. If you're experiencing a randomly occurring problem, being able to match activities performed with the memory status at the time may enable you to discover the cause of the problem. It also gives you a good indication of the health of the distributed server machine at the time any activity is performed. “ (Hatton, 2000) Commonly Logged Application Events (Defined by OWASP) Access of Data Creation of Data Modification of Data in any form Administrative Functions  Configuration Changes Debugging Information(Application Events)  Authorization Attempts  Data Deletion Network Communication  Authentication Events  Errors/Exceptions Application Error Logging The functionality associated with application error logging is actually the combination of proper error handling and applications logging.  If we look back at Figure 4 and Figure 5, these code examples allow developers to handle various types of errors that occur within the life cycle of an application’s execution. Application logging can be applied within the Catch section of the TryCatch statement allowing for the errors to be logged when they occur. By placing the logging within the Catch section specific error details can be accessed that help identify the source of the error, the path to the error, what caused the error and definition of the error that occurred. This can then be logged and reviewed at a later date in order recreate the error that was received based data found in the application log. By allowing applications to log errors developers IT staff can use them to recreate errors that are encountered by end-users or other dependent systems.

• Is this over-abstraction? (And is there a name for it?)

  - by mwhite

  I work on a large Django application that uses CouchDB as a database and couchdbkit for mapping CouchDB documents to objects in Python, similar to Django's default ORM. It has dozens of model classes and a hundred or two CouchDB views. The application allows users to register a "domain", which gives them a unique URL containing the domain name that gives them access to a project whose data has no overlap with the data of other domains. Each document that is part of a domain has its domain property set to that domain's name. As far as relationships between the documents go, all domains are effectively mutually exclusive subsets of the data, except for a few edge cases (some users can be members of more than one domain, and there are some administrative reports that include all domains, etc.). The code is full of explicit references to the domain name, and I'm wondering if it would be worth the added complexity to abstract this out. I'd also like to know if there's a name for the sort of bound property approach I'm taking here. Basically, I have something like this in mind: Before in models.py class User(Document): domain = StringProperty() class Group(Document): domain = StringProperty() name = StringProperty() user_ids = StringListProperty() # method that returns related document set def users(self): return [User.get(id) for id in self.user_ids] # method that queries a couch view optimized for a specific lookup @classmethod def by_name(cls, domain, name): # the view method is provided by couchdbkit and handles # wrapping json CouchDB results as Python objects, and # can take various parameters modifying behavior return cls.view('groups/by_name', key=[domain, name]) # method that creates a related document def get_new_user(self): user = User(domain=self.domain) user.save() self.user_ids.append(user._id) return user in views.py: from models import User, Group # there are tons of views like this, (request, domain, ...) def create_new_user_in_group(request, domain, group_name): group = Group.by_name(domain, group_name)[0] user = User(domain=domain) user.save() group.user_ids.append(user._id) group.save() in group/by_name/map.js: function (doc) { if (doc.doc_type == "Group") { emit([doc.domain, doc.name], null); } } After models.py class DomainDocument(Document): domain = StringProperty() @classmethod def domain_view(cls, *args, **kwargs): kwargs['key'] = [cls.domain.default] + kwargs['key'] return super(DomainDocument, cls).view(*args, **kwargs) @classmethod def get(cls, *args, **kwargs, validate_domain=True): ret = super(DomainDocument, cls).get(*args, **kwargs) if validate_domain and ret.domain != cls.domain.default: raise Exception() return ret def models(self): # a mapping of all models in the application. accessing one returns the equivalent of class BoundUser(User): domain = StringProperty(default=self.domain) class User(DomainDocument): pass class Group(DomainDocument): name = StringProperty() user_ids = StringListProperty() def users(self): return [self.models.User.get(id) for id in self.user_ids] @classmethod def by_name(cls, name): return cls.domain_view('groups/by_name', key=[name]) def get_new_user(self): user = self.models.User() user.save() views.py @domain_view # decorator that sets request.models to the same sort of object that is returned by DomainDocument.models and removes the domain argument from the URL router def create_new_user_in_group(request, group_name): group = request.models.Group.by_name(group_name) user = request.models.User() user.save() group.user_ids.append(user._id) group.save() (Might be better to leave the abstraction leaky here in order to avoid having to deal with a couchapp-style //! include of a wrapper for emit that prepends doc.domain to the key or some other similar solution.) function (doc) { if (doc.doc_type == "Group") { emit([doc.name], null); } } Pros and Cons So what are the pros and cons of this? Pros: DRYer prevents you from creating related documents but forgetting to set the domain. prevents you from accidentally writing a django view - couch view execution path that leads to a security breach doesn't prevent you from accessing underlying self.domain and normal Document.view() method potentially gets rid of the need for a lot of sanity checks verifying whether two documents whose domains we expect to be equal are. Cons: adds some complexity hides what's really happening requires no model modules to have classes with the same name, or you would need to add sub-attributes to self.models for modules. However, requiring project-wide unique class names for models should actually be fine because they correspond to the doc_type property couchdbkit uses to decide which class to instantiate them as, which should be unique. removes explicit dependency documentation (from group.models import Group)

• SBS 2008 Backup Drive Full - Error Code '2147942512'

  - by HK1

  We are using Windows Backup on SBS 2008 SP2 and backing up to 1TB external hard drives. Recently after switching drives our backup started failing because the backup drive is full and auto-delete isn't automatically deleting older backups/show copies. I'm trying to get more information to help me effectively prevent this problem from reoccurring in the future. How I can tell that the drive is getting full: In the event viewer under Windows Logs Application, I'm seeing Event ID 517 but it fails to show an intelligible description. However, under Applications and Services Logs Microsoft Windows Backup Operational, I'm seeing an event with the ID of 5 and a description like this: Backup started at '10/4/2011 12:30:12 PM' failed with following error code '2147942512'. One of the most informative posts I've found on this error is located on Microsoft's Technet Forums here. In that post, a Microsoft representative gives this hazy explanation: auto-delete feature to ensure that at least some old backup copies are maintained on the disk -- does not automatically delete backups if space utilization by older copies is less than 1/8 of the disk size or in other words, 13% of the disk size. that means if the one full backup copy does not fit in the 7/8 of the disk size, backup may fail with disk full error. auto-delete will not automatically delete older versions to reclaim more older versions of backup. In the above explanation, I do not understand what is meant by "older copies" except that it appears that anything older than the very last shadow copy would be considered "older copies". I'm going to make the assumption that this problem where auto-delete will not work will affect any hard drive that is large enough to make an effective backup drive, or in other words, any hard drive that is large enough to hold more than one backup/shadow copy at once. The same MS representative proposes the solution of using a larger backup drive. I can't understand how this will help. It appears to me it will simply delay the problem until a later date. In order to resolve this problem for now, I did the following: Assign the backup drive a disk letter under disk management. Run the command line with Administrative rights. diskshadow.exe [enter] delete shadows oldest x: [enter] (where X: is the letter you assigned your backup drive) I manually ran the above command some 60 or 80 times to free up about 200 GB of space on my 1 Terrabyte External Hard drive. However, I do not feel this is a satisfactory solution to prevent the problem from happening again in the future. Does anyone have a solution to prevent your Windows Server backup drive from getting full?

• How can I centralise MySQL data between 3 or more geographically separate servers?

  - by Andy Castles

  To explain the background to the question: We have a home-grown PHP application (for running online language-learning courses) running on a Linux server and using MySQL on localhost for saving user data (e.g. results of tests taken, marks of submitted work, time spent on different pages in the courses, etc). As we have students from different geographic locations we currently have 3 virtual servers hosted close to those locations (Spain, UK and Hong Kong) and users are added to the server closest to them (they access via different URLs, e.g. europe.domain.com, uk.domain.com and asia.domain.com). This works but is an administrative nightmare as we have to remember which server a particular user is on, and users can only connect to one server. We would like to somehow centralise the information so that all users are visible on any of the servers and users could connect to any of the 3 servers. The question is, what method should we use to implement this. It must be an issue that that lots of people have encountered but I haven't found anything conclusive after a fair bit of Googling around. The closest I have seen to solutions are: something like master-master replication, but I have read so many posts suggesting that this is not a good idea as things like auto_increment fields can break. circular replication, this sounded perfect but to quote from O'Reilly's High Performance MySQL, "In general, rings are brittle and best avoided" We're not against rewriting code in the application to make it work with whatever solution is required but I am not sure if replication is the correct thing to use. Thanks, Andy P.S. I should add that we experimented with writes to a central database and then using reads from a local database but the response time between the different servers for writing was pretty bad and it's also important that written data is available immediately for reading so if replication is too slow this could cause out-of-date data to be returned. Edit: I have been thinking about writing my own rudimentary replication script which would involve something like having each user given a server ID to say which is his "home server", e.g. users in asia would be marked as having the Hong Kong server as their own server. Then the replication scripts (which would be a PHP script set to run as a cron job reasonably frequently, e.g. every 15 minutes or so) would run independently on each of the servers in the system. They would go through the database and distribute any information about users with the "home server" set to the server that the script is running on to all of the other databases in the system. They would also need to suck new information which has been added to any of the other databases on the system where the "home server" flag is the server where the script is running. I would need to work out the details and build in the logic to deal with conflicts but I think it would be possible, however I wanted to make sure that there is not a correct solution for this already out there as it seems like it must be a problem that many people have already come across.

• WSS and CAG , _layout pages break

  - by Mike

  Alright, I've searched everywhere and I cannot find the answer, due to the rarity of our setup. WSS 3.0/IIS 6.0/WinServer 2003 We have a sharepoint site that is in good shape, almost. Its TCP and SSL port are uncommon and need to be rerouted to work properly. This is where the Citrix Access Gateway (CAG) comes in play. It will redirect any request from URL (something.something.com) to the correct SSL port on the correct server. My AAM is configured to Default something.something.com and nothing else, since the CAG will provide the port. We use FBA, and require SSL. This works perfectly for everything that is safe or that is anything that an end user can see, but if I try to add a webpart, it errors out. Whereas if I add it internally, or bypass the CAG the webpart adds fine. The same goes for most of the _layouts pages, like _layouts/new.aspx. If I add a Link List/Doc library on the something.something.com, it errors out (Page cannot be displayed) and the page won't display, but if I try it with an internal address it will work fine. I found that if I am trying to add something or doing anything administrative, the site will navigate to the pages that I need to go to fine, but when i actually ADD something the URL will change from something.something.com to something.something.com:SSLport, thus erroring out the site. The URL with the SSL port shows on the Site URL when navigating to Site Settings. However, if I bypass the CAG, using the internal address the _layouts page works like a charm and i can add anything. All the CAG does is reroute a DNS request to the provided server and port. I've tried reextending the application, no luck same thing. I've tried changing the AAM to hide the port and the CAG rejects it. I've tried to recreate a new webapp/site collection with the same rules on the CAG, same thing occurs. Correct me if I'm wrong, and please provide me with some feedback and answers. Any suggestions would be very appreciated. Is it the CAG or the Alternate Access Mappings (AAM)?

• Moving from single-site to multi-site Active Directory has broken OWA proxying

  - by messick

  Originally we had the following setup: OfficeExch01 has Mailbox Role and CAS Role OfficeExch01 is in the office. CoLoExch01 had just CAS Role. CoLoExch01 is internet facing and in a CoLo. Three AD domain controllers in the default site. Users could go to https://webmail.whatever.com/owa, get proxyed to OfficeExch01 and everything was great. Well, we recently setup a separate AD site and put a domain controller and the ColoExch01 server in the new site. I also made that remote DC be a Global Catalog. Now, users get the following error: Outlook Web Access is not available. If the problem continues, contact technical support for your organization and tell them the following: There is no Microsoft Exchange Client Access server that has the necessary configuration in the Active Directory site where the mailbox is stored. I also see event 41 errors in the logs: The Client Access server "https://webmail.xxxxxxx.com/owa" attempted to proxy Outlook Web Access traffic for mailbox "/o=XXXXX/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=xxxxxxk". This failed because no Client Access server with an Outlook Web Access virtual directory configured for Kerberos authentication could be found in the Active Directory site of the mailbox. The simplest way to configure an Outlook Web Access virtual directory for Kerberos authentication is to set it to use Integrated Windows authentication by using the Set-OwaVirtualDirectory cmdlet in the Exchange Management Shell, or by using the Exchange Management Console. If you already have a Client Access server deployed in the target Active Directory site with an Outlook Web Access virtual directory configured for Kerberos authentication, the proxying Client Access server may not be finding that target Client Access server because it does not have an internalUrl parameter configured. You can configure the internalUrl parameter for the Outlook Web Access virtual directory on the Client Access server in the target Active Directory site by using the Set-OwaVirtualDirectory cmdlet. Looking this up I see a lot talk about ExternalURL and InternalURL settings. However, everything worked great until we made the new AD site. I also made sure the internal CAS server's /owa virtual directory is set to use Integrated Authentication. Is there something I need to do to allow Exchange to see that I've made these AD changes?

• Strange permission errors with Windows Server 2008

  - by Spirit

  I just don't know a better way to describe my issue that is driving me nuts. I am trying to establish a test domain with virtual machines on a box that has Win7 with VMwware workstation installed. The purpouse with this domain will be so that we can try and test different situations before they go into the production network. I build a VM with WinSrv2008R2 and I am using that VM as a template to make other servers for the domain by making clones of it. Now I raise a DC with one clone and a member server with another clone - I add the server to the domain. I am following a standard procedure as always (it is not my first domain). Then I make an admin account and I am adding the admin to be a member of the Domain and Enterprise Admins group. That admin is admin with full priviledges on the DC.. no problem there. But on the other server has ... somewhat half the privileges and I cant log in via RDP. I tryed with another account. Same issues. For example (with half the privileges): I can't open the Even Viewer if I go via Start - Administrative Tools - Event Viewer. But I can open the Even Viewer via the server manager. You can notice this on the image below. I mean WTF??? I am going crazy, I haven't experienced anything similar in my three years of expertise. I already lost 3 days troubleshooting this. Could this be related with the cloning? Perhaps if I make fresh installs of WinSrv2008 there won't be any problems? I've had raised test domains as VMs on other occasions before, and there weren't any problems then. This is VMware Workstation 8. I've made clones before, on Workstation 7 it didn't had any problems. Anyone has any ideas? UPDATE: This is the info from the event log when I try to access via RDP: An account failed to log on. Subject: Security ID: NULL SID Account Name: - Account Domain: - Logon ID: 0x0 Logon Type: 3 Account For Which Logon Failed: Security ID: NULL SID Account Name: pat.coleman Account Domain: lab Failure Information: Failure Reason: Domain sid inconsistent. Status: 0xc000006d Sub Status: 0xc000019b

• 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.

• Gartner PCC Follow-up: Interview with Chaeny Emanavin, Usability Lead - Office of Information Develo

  - by [email protected]

  Last week at the Gartner Portals, Content and Collaboration conference in Baltimore, Chaeny and I co-presented on Oracle Enterprise 2.0 and BIA's Citizen Portal. Chaeny's presentation about the BIA solution was very well received and I wanted to do a follow-up interview with Chaeny to discuss more details about their solution and its Enterprise 2.0 features. Ajay: What were the main objectives for the BIA Citizen Portal? Chaeny: The BIA Citizen Portal is designed to provide all the services of the Bureau of Indian Affairs to the community of 564 federally recognized tribes that include over 1.9 million American Indians and Alaska Natives. The BIA provides the same breadth of services that the entire U.S. Federal Government provides in one small Bureau. So, we needed a solution that was flexible enough to handle content ranging from law enforcement to housing to education. Key objectives for external users was to use the Web as a communications channel and keep them informed on what services are available. We also wanted to build an internal web presence and community for BIA's 5000 employees to ensure that they update their content, leverage internal experts and create single sources of truth for key policy documents. Ajay: How is the project being implemented? Chaeny: We are using a phased approach. In phases 1 & 2, interim internal and external sites were built to ensure usability and functional requirements are being met. In Phases 3 & 4, we built out a modern internal and external presence using Oracle WebCenter Suite and Oracle Universal Content Management (UCM), including enabling delegated content management for our internal business units. Phase 4 was completed in January 2010. Phase 5 will add deeper Enterprise 2.0 collaboration capabilities to the solution. Ajay: Are you integrating any existing sites into the new solution? Chaeny: Yes, we have a SharePoint implementation that we are using for document management. We needed more precise functionality however. We found that SharePoint would let individual administrators of a SharePoint site actually create new sites. In a 3 months span, we had over 200 new sites created and most were not being used. So, we had an enormous sprawl problem. Our requirements mandated increased governance and more granular control over the creation of sites and flexible user access to content. In SharePoint this required custom code and was very time-intensive which was unfeasible given our tight deadlines. We are piloting Oracle WebCenter Spaces as our collaboration solution to mitigate these issues. However, we must integrate our existing SharePoint investment which we can do easily by using the SharePoint connectors available in Oracle WebCenter and UCM. Ajay: What were the key design parameters for your solution? Chaeny: We wanted everything driven by standards and policies. We created a cross-functional steering group called the Indian Affairs Web Council to codify policies that were baked into the system. Other key design areas were focused on security/governance, self-service content management, ease of use, integration with legacy applications and seamless single sign-on. We are using Dublin Core as our metadata standard. We also are using Java, APEX, and ADF as our development standards. Ajay: Why was it important to standardize on a platform? Chaeny: We initially looked at best-of-breed solutions, but we faced a lot of issues getting the different solutions to work together. Going with an integrated solution was more economical, easier to learn and faster to deliver the solution. Ajay: What type of legacy applications are you integrating into the portal? Chaeny: Initially we are starting with administrative apps such as people directory and user admin and then we will integrate HR and Financial applications among others. Ajay: Can you describe some of the E20 collaboration features you are putting into the solution? Chaeny: We are adding Enterprise 2.0 using Oracle WebCenter Spaces to deliver different collaboration tools such as wikis, blogs and discussion forums. Wikis to create rapid, ad hoc monthly roll-up reports; discussion forums to provide context-specific help; blogs to capture tacit organization knowledge from experts, identify gurus and turn tacit knowledge into explicit knowledge. Ajay: Are you doing anything specifically to spur adoption and usage? Chaeny: Yes, we did several things that I think helped us ramp quickly. First, we met our commitments for the new system launch date and also provided extra resources for a customer support "hotline" during the launch period. Prior to launch, we did exhaustive usability studies to capture user requirements around functionality, navigation and other key interaction areas. We also created extensive training programs so that the content managers in each business unit were comfortable using the content management tools and knew the best practices for usage. Finally, to launch the Enterprise 2.0 collaboration capabilities, we are working with a pilot group from the Division of Forestry and Wildland Fire Management of BIA. This group of people in the past have been willing early adopters and they have a strong business need to collaborate with many agencies both internal and external across State, County and other Federal jurisdictions. Their feedback is key to helping us launch Enterprise 2.0 successfully in our broader organization. Ajay: What were the biggest benefits to internal BIA employees and to the external community of users? Chaeny: For our employees, the new Enterprise 2.0-based solution will make it easier to find information; enhance employee productivity by embedding standard business processes into the system and create more of a community by creating connections with experts via social collaboration to ultimately provide better services more quickly. For the external American Indian and Alaska Native communities, we have a better relationship with the users and the new site has improved BIA's perception as a more responsive and customer-centric organization.

• Leaks on Wikis: "Corporations...You're Next!" Oracle Desktop Virtualization Can Help.

  - by adam.hawley

  Between all the press coverage on the unauthorized release of 251,287 diplomatic documents and on previous extensive releases of classified documents on the events in Iraq and Afghanistan, one could be forgiven for thinking massive leaks are really an issue for governments, but it is not: It is an issue for corporations as well. In fact, corporations are apparently set to be the next big target for things like Wikileaks. Just the threat of such a release against one corporation recently caused the price of their stock to drop 3% after the leak organization claimed to have 5GB of information from inside the company, with the implication that it might be damaging or embarrassing information. At the moment of this blog anyway, we don't know yet if that is true or how they got the information but how did the diplomatic cable leak happen? For the diplomatic cables, according to press reports, a private in the military, with some appropriate level of security clearance (that is, he apparently had the correct level of security clearance to be accessing the information...he reportedly didn't "hack" his way through anything to get to the documents which might have raised some red flags...), is accused of accessing the material and copying it onto a writeable CD labeled "Lady Gaga" and walking out the door with it. Upload and... Done. In the same article, the accused is quoted as saying "Information should be free. It belongs in the public domain." Now think about all the confidential information in your company or non-profit... from credit card information, to phone records, to customer or donor lists, to corporate strategy documents, product cost information, etc, etc.... And then think about that last quote above from what was a very junior level person in the organization...still feeling comfortable with your ability to control all your information? So what can you do to guard against these types of breaches where there is no outsider (or even insider) intrusion to detect per se, but rather someone with malicious intent is physically walking out the door with data that they are otherwise allowed to access in their daily work? A major first step it to make it physically, logistically much harder to walk away with the information. If the user with malicious intent has no way to copy to removable or moble media (USB sticks, thumb drives, CDs, DVDs, memory cards, or even laptop disk drives) then, as a practical matter it is much more difficult to physically move the information outside the firewall. But how can you control access tightly and reliably and still keep your hundreds or even thousands of users productive in their daily job? Oracle Desktop Virtualization products can help.Oracle's comprehensive suite of desktop virtualization and access products allow your applications and, most importantly, the related data, to stay in the (highly secured) data center while still allowing secure access from just about anywhere your users need to be to be productive.  Users can securely access all the data they need to do their job, whether from work, from home, or on the road and in the field, but fully configurable policies set up centrally by privileged administrators allow you to control whether, for instance, they are allowed to print documents or use USB devices or other removable media.  Centrally set policies can also control not only whether they can download to removable devices, but also whether they can upload information (see StuxNet for why that is important...)In fact, by using Sun Ray Client desktop hardware, which does not contain any disk drives, or removable media drives, even theft of the desktop device itself would not make you vulnerable to data loss, unlike a laptop that can be stolen with hundreds of gigabytes of information on its disk drive.  And for extreme security situations, Sun Ray Clients even come standard with the ability to use fibre optic ethernet networking to each client to prevent the possibility of unauthorized monitoring of network traffic.But even without Sun Ray Client hardware, users can leverage Oracle's Secure Global Desktop software or the Oracle Virtual Desktop Client to securely access server-resident applications, desktop sessions, or full desktop virtual machines without persisting any application data on the desktop or laptop being used to access the information.  And, again, even in this context, the Oracle products allow you to control what gets uploaded, downloaded, or printed for example.Another benefit of Oracle's Desktop Virtualization and access products is the ability to rapidly and easily shut off user access centrally through administrative polices if, for example, an employee changes roles or leaves the company and should no longer have access to the information.Oracle's Desktop Virtualization suite of products can help reduce operating expense and increase user productivity, and those are good reasons alone to consider their use.  But the dynamics of today's world dictate that security is one of the top reasons for implementing a virtual desktop architecture in enterprises.For more information on these products, view the webpages on www.oracle.com and the Oracle Technology Network website.
