How to recover database corruption errors that you encounter in Oracle database

How to recover database corruption errors that you encounter in Oracle database

Oracle Database is one of the most reliable and secure RDBMS (Relational Database Management Systems) from Oracle Corporation. Also, this database is one of the first RDBMSs to allow the capability to read/write XML statements. The information of the Oracle database is stored in a proprietary file called the DBF (Database File) file, which sometimes get corrupt thereby disabling you from using it. But Oracle provides different methods to eradicate database corruption of varying levels. If you are unable to sort the error even after using these methods, then I would suggest you to use third-party Oracle database recovery software to recover Oracle database.


Let us have a look at few of the error messages that you may encounter either while working or while opening an Oracle database


ORA-01043: user side memory corruption
ORA-01073: fatal connection error: unrecognized call type
ORA-01053: user storage address cannot be read
ORA-01079: Oracle database was not properly created, operation aborted

Cause:


The most prominent cause of these error messages is that the Oracle database has damaged. The reasons for the database corruption could be either of the ones mentioned in the introductory paragraph.


Resolution:


As the error messages may have occurred at different phases or user actions, there are different type of resolving methods that are provided in Oracle. Some of the most used methods are:


DBVerify: You should use this external utility to validate the offline and backup data files.
ANALYZE .. VALIDATE STRUCTURE: This command is used to check each and every block of the scanned object. If any corruption is found in the object, then the detected rows are moved to the INVALID_ROWS table.
DB_BLOCK_CHECKING: Using this method, you can set its parameter to 'TRUE' to check each and every block of the database object to check if it is self-consistent. This method adds about 1% to 10% overhead to the server. So, you should use this method if this much overhead is acceptable to you.
DBMS_REPAIR: This tool is actually does two tasks in a go. Unlike the previously discussed methods, it detects and repairs database corruption on its own.

You would be able to address all the errors after performing these methods. However, if this is not so then you should use third-party Oracle database recovery software. These DBF recovery tools are very safe to use that do not modify the already damaged Oracle database.


The best Oracle database recovery software, which recovers Oracle database created for Oracle 9i, 10g, and 11g versions, is Stellar Phoenix Oracle Database Recovery. Compatible with Windows Server 2003 and XP, this DBF recovery utility recovers DBF file by restoring various objects including tables, roles, views, table spaces, cluster tables, schemas, synonyms, indexes, and sequences.

Embedded Control-Record Layouts Improve Database and RFID Sensor Testing

Embedded Control-Record Layouts Improve Database and RFID Sensor Testing

Software application designers and hardware application developers are working as teams to incorporate control-record layouts into end-to-end XML services for RFID networks.  Using these newly formed XML tag sets made up of customized control-records has improved the design and development scenarios across diverse hardware platforms, operating systems, applications, and databases.


As software application developers begin to build RFID-and-sensor networks within key growth areas, it has become common place to witness recent deployments of control-record structures embedded in sensors and their supporting software. These control records contribute immensely to the major functions of any RFID sensor application including inputs, data-lookup and storage, interface programming and outputs.  


These five major features are now incorporated into the application as a new and more efficient XML and database schema. This improved configuration has proven to meet growing demands to test multi-vendor RFID and sensor products for their ability to withstand extreme conditions.  These conditions include excessive heat and cold, shock, humidity, vibration, altitude, pressure and all are reliably monitored using the new control-record layout approach.


The key design feature in the programming arrangement described in this article is the idea that an intermediate control record receives and distributes signals to and from the software and hardware sides of the full application. This nicely integrates selected signals from both spheres of operation and allows an interface to adapt dynamically to different device types. As new devices are attached and configured with the application, no appreciable interference is noticed in the originally attached devices.


Because the embedded layout of many types of devices can be addressed through the use of control records, new applications are provided with better XML testing languages. Additionally, this feature provides designers with the opportunity to introduce database simulators for a more accurate and dynamic portrayal of RFID and Sensor operation.  This dynamic portrayal is added to the accumulated testing history and a better picture of performance emerges.


As RFID becomes more widely deployed, network reliability, security, and data integrity become increasingly critical. And for most companies, the task of ensuring those three things will be overwhelming and complex, especially across multiple hardware platforms and configurations and diverse supplier and partner networks and databases.


But because it is now feasible to virtually attach these control-record layouts to alleviate some of the major complexities associated with the required tests, any company can develop new products that may have been prohibitive in the past.

Business Database: The Key In B2b Leads

Business Database: The Key In B2b Leads
Why are B2B leads so hard to find? Well, there are a lot of things to consider. After all, telemarketing isnt exactly the goose that lays the golden egg these days. Lead generation can be a sluggish challenge, with the chances of success small. Still, the rewards can be great when it comes to success. Its how to manage the different factors of a telemarketing campaign can we be able to decide if the entire endeavor is a success or not. These factors, when left on their own, can easily wreck the whole operation.

The first factor to consider is the telemarketers doing the call. Not everyone can be a telemarketer. It takes a lot of guts and patience on the part of those making the calls in order to get those successes. And since this type of work is particularly stressful, telemarketers must have a very high tolerance for it. Conversely, only the best and the toughest agents would be able to last long and still be able to get the job done. But since theyre also human, they are bound to hit some problems. To reduce those problems, telemarketing services provide them with a comprehensive contact list that they can look up when they make the call, or when they need some fast information.

The target market is another factor to consider as well. B2B leads are best obtained from firms whose decision makers are very responsive to the telemarketers offers. Thats why it takes a lot of skill from telemarketers just to get the right prospects to do business with. Of all the things that can make a campaign difficult, its the reluctance of the prospect to accept just what exactly the business had to offer. Oftentimes, the end result is an outright rejection. Even so, its still good for you to keep on doing it. There is still the chance that a call can be a success, so just continue calling up those prospects.

Next in the list is the sales pitch. Everyone knows that it takes a lot of research and careful planning to execute a successful telemarketing campaign. Making a sales script is no exception to the rule. Often, the main reason why a call fails is because the telemarketers use a script that does not reflect the way a prospect wants to hear about an offer. Frankly, there is a need to put things in a perspective. People like to listen to a conversation that flows smoothly. A canned speech patter merely irritates them and turns them off. A skilled telemarketer would be able to handle that, and succeed in making a successful attempt to make a sale or generate B2B leads.

Lastly, its the products and services themselves that need to be examined. As a telemarketer, you should take a good look at what youre offering to prospective customers. Poor products make for poor performance, with the accompanying complaints from customers who buy them. This is what you should avoid, since bad publicity can destroy not just what youre selling, but your reputation as well.

Now, to get things going in the least possible time and effort, there are many business database providers who give round-the-clock information to interested parties. These firms are at the forefront of information gathering and analysis and they are the best source of contact list for their campaign. Telemarketers around the world swear to the dependability of these businesses. Not only did they make their lives easier, they also made the job much more profitable. Truly, a wise investment anyone can ever make. Its high time for you to try it out now.
