Oracle 11g And How it Can Help Your Business


By 
SQL 2012 and Oracle are relational database management systems (RDBMS) designed to store, organize, and present large amounts of data in tables. Users should consider their organization's needs, existing software infrastructure, and technical knowledge when weighing the two platforms. Except for their handling of "Big Data," SQL 2012 and Oracle offer comparable features, though the preponderance of Microsoft's Business Intelligence software may make it a more attractive choice for many users.
Oracle's trump over past SQL incarnations was usually rooted in the former's ability to analyze and store Big Data. Microsoft's response was to integrate Hadoop into SQL 2012, thus giving SQL the ability to examine and coherently present overwhelming amounts of unrelated datasets. It should be noted, however, that Hadoop will not be available for SQL 2012 until mid-2012. It remains to be seen whether this integration will meet user expectations for Big Data analysis. Until such time, Oracle has already released their Big Data Appliance featuring Hadoop and Cloudera; users with the immediate need to analyze unstructured massive datasets throughout thousands of networked computers might not want to wait for Hadoop's integration into SQL 2012.
One simple point to consider is the question of the user's operating system. SQL 2012 runs only on PCs running Server 2008, Windows 7, or Vista. Oracle's supported systems are more versatile; these include Linux, Windows, Unix, OS/390, Mac OSX, and OpenVMS. This broad approach, while flexible, also potentially presents a more convoluted installation process than the narrowly-focused SQL 2012.
Microsoft's hegemony gives SQL 2012 users their entire Business Intelligence (BI) suite. SQL integrates with SharePoint, PowerPivot, Excel, Analysis Services, Integration Services, Master Data Services, and others. The widespread use of these tools makes finding online support relatively simple, as does the singularity of their operating system. Oracle Enterprise Edition (Oracle XE) offers comparable functionality, though if a company or user has already licensed much of Microsoft's BI software, they may balk at the cost of acquiring another license.
Along with cost, users must consider the type and scope of probable use when choosing between the two platforms. SQL 2012 requires licensing fees on a "per-core" basis. Oracle offers a free version of Oracle XE with some caveats. These limitations include a 4 GB limitation on stored data, a 1 GB cap on Random Access Memory usage, and the free edition will not use more than on Central Processing Unit, even if the host machine contains more. The licensed version of Oracle XE also bases its cost on the "per-core" structure.
Users should consider their operating system, budget, existing BI infrastructure, and Big Data needs before committing to either SQL 2012 or Oracle. From a functionality standpoint, most users will find either to be adequate for their Business Intelligence needs if Microsoft successfully integrates Hadoop into SQL 2012.

Microsoft SQL Server 2012 Vs Oracle



By 

I recently upgraded my Linux installation to the latest OpenSuSe 11.2 release and then decided to install also the free version of the Oracle database (Oracle-XE or Oracle Express)..
The installation of Oracle consists of the following main steps:
a) Download Oracle from the Oracle site
The site contains different download files for Windows and some versions of Linux. Since the package management in OpenSuSe Linux is based on rpm, I downloaded an rpm file.
b) Log in on your system as a root user
c) install the rpm file with the command
rpm -ivh oracle-xe-univ-10.2.0.1-1.0.i386.rpm
d) execute the initial configuration of the database by running the command:
/etc/init.d/oracle-xe configure
The command will ask you to choose the HTTP port, the listener port, the Sys and System password and I suggest to keep the suggested default values (i.e HTTP port=8080 and listener port= 1521), The system will also ask if you want to start the database automatically at boot time (I choose the yes answer).
e) After the configuration the system automatically starts the Net Listener and the Oracle database 10G Express. It prints a completion message that the Installation completed successfully and then suggests to access the database Home page by entering on your browser the command
127.0.0.1:8080/apex
f) I did as instructed, but the command was refused because it could not be executed on the server. At the point I started panicking and I thought that I must have made some errors. I decided to uninstall Oracle by running the command
rpm -e oracle-xe-univ
Then I re-installed from scratch. Unfortunately the results were exactly the same.
g) Finally I wondered if the problem might be connected to the Web server. I decided to install Apache (not installed by default) and to to re-install Oracle again. This time everything worked perfectly.
I found on various Linux Forums that many people seem to have this problem and I suggest them to try an installation of Apache before installing Oracle.

How to Install Oracle on OpenSuSe Linux

I have worked with Oracle Express Edition for 32-bit environments long as it is easy to have the characteristics of a dataset Oracle Enterprise without the need to install it. However installation Oracle Express Edition (XE) by 64 bits is not always successful. You can find XE working on your first installation itself, if you know the trick. Oracle does not provide a separate Oracle 11g XE for 64-bit installation, but you can download the 32-bit version and install the 64-bit operating system. Follow these tips for a successful installation of Oracle XE.

1. Disable Windows Firewall / any other firewall in your system.
2. Unplug the network cable.
3. Run the installer and complete the setup.
4. Open command prompt, and execute hostname command to get the name of the system where you are installing. Assume the command produces “MySystem” as output.
5. Navigate to <drive>:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN folder. Makesure that the host name from Step 4 matches the entry in the tnsnames.ora file found under the folder. The tns entry should like the following:
XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MySystem)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )
Thats is it. WOLA !!! You have made it. Your installation of Oracle XE is successful. You can plug your network cable back on, and enable the firewall.
