• basic questions about the Bigdata, NOSQL, and Hadoop

  
  Hello

  I have fundamental questions related to Bigdata. (I have Googled it but still want to confirm with experts)

  Please correct me if I'm wrong on below.

  (1) as far as I know data large are the collection of unstructured data. We can even store relational data as well.

  (2) NOSQL is a product of Oracle to manage bigdata (UN structured data and relational data as well)

  (3) Hadoop is the only framework that is available on the market to manage the bigdata.

  What are the other systems of database that we have in the market to manage the bigdata.

  See you soon,.

  Suri,

  NoSQL is a distributed (with indexing and schematics) database. From a database point of view, NoSQL is a good place to start you off. Hadoop is a framework for distributed processing, rather than a database. If you are looking to take advantage of your database skills, then I suggest starting with NoSQL.

  Oracle Press has recently published "Oracle Big Data Handbook," which is an overview of the suite of large data Oracle technology products. I would start there. You can find the book on Oracle Press or Amazon , Barnes & Noble.

  I hope this helps.

  Kind regards

• Create the data source NoSQL Oracle using Oracle Weblogic 11 g

  Hello

  I'm working on a VINE by which I want to connect NoSQL Oracle database with Oracle Weblogic11g as a new source of data in Oracle Database 11 g of accompaniment.

  So my question is that Oracle Weblogic 11 g support NoSQL Oracle database as a data source OR can I plug NoSQL Oracle database as the source of data with Oracle Weblogic11g?

  Thank you...

  Hello

  By 'data source' I assume you mean a JDBC data source. Is this fair?

  If so, please be aware that NoSQL DB does not support SQL or JDBC, although these features can be added in the future. Currently, to access data in the NoSQL database from your application, you must use the Java APIs in the pilot of the client which is included in the package. Please see the Starter Guide for more information.

  That answer your question?

• The problem of the distribution of the data in the cluster of NoSQL Oracle databases

  Hello

  I write (about 10 G) data in an Oracle Databae NoSQL cluster (which consists of three nodes: ud1, Node2, node3). It has only one table in the DB and I create an index on a field.

  The amount of data in each node is about 16G.

  Then I write the same data (about 10G) in an Oracle NoSQL Database (Only one node) and I create an index on the same lot.

  But the amount of data is about 46G.

  So I assumed that each node holds no data complete. Then if the failure of a node, the cluster can still work but some data cannot be queried. Am I wrong?

  There is an intersection in the form of database on each node?

  You should take a look at the documentation. For example:

  http://docs.Oracle.com/CD/NoSQL/HTML/AdminGuide/introduction.html

  Hi Joguerra,

  Currently, the semantic graph RDF for Oracle NoSQL Database can't vocabulary GeoSPARQL. You can, however, use semantic graph RDF for Oracle Database (12 c) and it comes with a GeoSPARQL support.

  There is a strong requirement to have some features Geo space with RDF for Oracle NoSQL Database, please file a feature request.

  I created an ontology on 4.3 protected it seems good. I added the plugin NoSQL protégé and I saved the model and inference in the database.

  Hi MEMU,.

  I have it. And he has deployed in the built-in container. It works very well. Note that I did the following.

  (1) change the project properties,

  In the libraries and Classpath, I need to add in Classpath entries associated Jena libraries, slf4j, sdordfnosqlclient.jar, kvclient.jar etc.

  (2) use the xercesImpl - 2.9.1.jar instead of xercesImpl - 2.10.0.  Jdev 12 c appears to use an older version of xerces as bundles of Jena.

  Once done the configurations above, I can execute your project without changing Java code.

  Any ideas?

  Thank you

  Jason

  OK, I was able to solve my problem by uninstalling yum cmake and manually build the latest version of CMake - Cross platform make. (to date, the current stable version is 2.8.12.2).

  Very simple installation

  wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz

  tar - xvvf cmake - 2.8.12.2.tar.gz

  CD cmake - 2.8.12.2

  . / bootstrap

  do

  make install

  update your PATH

  After that, I was able to run cmake again for c - kv - 2.1.57 successfully.

  But then I met another problem over do it with the following error message:

  LD WARNING not found libmawt.so (not exact error, do not remember)

  /usr/lib/JVM/JRE/lib/AMD64/libjawt.so: refers to 'awt_FreeDrawingSurface@SUNWprivate_1.1' the undefined

  ...

  To resolve this problem, I ran:

  Locate libmawt.so

  Choose the one with jre/lib/amd64/xawt and set that RPATH path in my environment.

  Export RPATH = / your/path/may/change/jre/lib/amd64/xawt

  Then ran once again. Then make install. Success!

  Hope this helps someone else.

  Thank you

• How to change hadoop-model?

  Hello

  Because my DNS does not record IP dynamicaly, I need to get hadoop-model VM and edit/etc/hosts to add some records...

  But I do not understand how to connect to this virtual computer? I don't know IP or credentials...

  Configuration:

  BDE 2.1.0

  vCenter 5.5u2

  Procedure:

  1 turn on the virtual machine of Hadoop model and apply updates or changes.

  2 remove the /etc/udev/rules.d/70-persistent-net.rules file in order to avoid the multiplication of EPF in the clone operation.

  You must remove this file, otherwise, the virtual machine cannot obtain its IP address.

  If you do not remove the /etc/udev/rules.d/70-persistent-net.rules file, virtual machine cloned from the model is unable to obtain an IP address. If you turn on this virtual machine to make changes, you must remove this file before you shut down the virtual machine.

  3 close the virtual machine of Hadoop model.

  4 remove the labeled serengeti-instant snapshot in VM of Hadoop model custom.

  one

  In the vSphere Web Client, right-click the virtual machine of Hadoop model and select snapshot > Snapshot Manager

  b

  Select the serengeti-snapshot, and then click on remove.

  The generated snapshot is automatically deleted.

  Thanks in advance

  You can connect vSphere Client or vSphere Web Client to connect the vCenter Server, search for the hadoop under BDE VAPP, hadoop-model model right click and select "Open Console", then you can connect it with password root.

• Get details of username and group of companies of Workflows Hadoop

  Hi people,

  We are able to deploy Hadoop Clusters successfully using vCAC - vCO integration. We strive to update the database with information such as the user name (who asked the Hadoop Cluster), company of the etc group, the problem is, we are not able to make the username and group business Details of the vCAC through the Hadoop Workflows in vCO. These details are the entries, attributes, nor outputs... However, the details are displayed. But, when the workflow starts we get details such as ID username and group of companies in vCO on the 'Variables' tab (shown in the image below).  Is there a way we can save this information?

  System.log (__asd_tenantref); -does not work.

  I think that these values are updated automatically through vCAC when the deployment of the cluster is started. Is there a way we can track this information?

  Thank you

I know it sounds like a silly question but I'm wanting to know if I can use of the Serengeti and basically create a set of virtual machines and IPs with defined storage and RAM. Then, I want to install my own packages, not Hadoop but Serengeti can create the initial virtual machines is so good.

  Thanks in advance,

  Carl.

  It worked, thanks. So I guess it was sudo sed-i "/ 'hadoop_namenode' / a 'basic', '/ opt/serengeti/www/distros/manifest"

  So thank you. He placed two VMS in pools of different resources. What config file defines what I do not see that it referenced in .json models in/opt/serengeti/conf.

• NoSQL Oracle under Windows.

  Hi all

  I am new to Oracle NoSQL, and I'm trying to develop the same application. so I do it on windows 7 OS. But cannot run kvclient on windows.

  So, how can I do?

  Please suggest me.

  Thanks in advance!

  Just to let you know, Windows is not an officially support platform for Oracle NoSQL Database.  You can use kvlite to get an idea of the NoSQL APIs and to test a simulated application, but we don't certify Windows as a product platform.  Are you referring to the kvlient.jat file when you say that you are unable to run kvlient on Windows?
