Advantages Of Ku Band Satellite Systems And Isp Technology

  • Posted on November 6, 2017 at 9:46 pm

There are many renowned satellite service providers who offer, earth station leasing and transponder leasing services to meet the short-term broadcasting and transmission requirements of the global clientele. With these services, one can easily increase the coverage areas and subscribers through Multipoint solutions, Point-to-Point solutions, and Broadcast and Multicast applications, to link remote provinces to the main switching network. You can select the desired bandwidth for the transponder leasing services. You can opt for C band, eKU band, DBS band, Ku Band, extended C band and Ku band satellite system for various transponder capacities. The best part is that transponder leasing facilities can also be availed for occasional short term audio or video transmission applications like live TV broadcasting of special events, program transmission or backhaul services etc.

The most popular band is satellite communication is Ku band. Unlike C band, Ku band satellite system is not restricted in power so as to prevent interference with terrestrial microwave systems. Thus, the power of its uplinks and downlinks can be easily increased as per the requirements. Higher power also means that one can use smaller receiving dishes. This is because the function of the dish antenna is to collect the incident waves over an area and focus them all onto the antenna’s actual receiving element, thus, if the waves are high in intensity, then less dish antenna will be sufficient to collect and achieve the same intensity at the receiving element.

With the revolutionizing changes occurring in the satellite technology, more and more people are turning to global internet service providers. Most reliable internet service providers offer high-end Internet Protocol Paradigm like dial-up, DSL, cable modem, wireless or committed high-speed connection, with the help of data transmission technology. Through the internet e-mail accounts provided by the internet service providers, one can easily transmit and receive electronic messages through their servers.
Wireless service is the most innovative and ground-breaking technology for the entrepreneurs and corporate all over the world who are looking forward to expand the scope of their local area networks. ISP backbone via satellite service is done by joining Wi-Fi or WIMAX technology with satellite backbone connectivity. With this, the clients have faster access to video streaming, IPTV, internet access and video conferencing over a wireless network. The wireless services through ISP backbone via satellite is widely used by internet cafes, businesses, or individual users, because it offers high-speed communication services even to the remote areas without installing cables or telephone lines.

Sql Server Database Corruption If You Run A Query With Parallel Execution Plan

  • Posted on November 6, 2017 at 2:02 am

You may come across Access Violation if you run an SQL query, which uses parallel execution plan in Microsoft SQL Server 2008. Access violation is an error condition, which may occur while performing general operations on the SQL database. It may occur due to application malfunction, software bug, or database corruption. It renders your database inaccessible and may cause data loss, if you don’t have a complete backup to restore data from. To overcome such issues, is required.

As an example of Access Violation in Microsoft SQL Server 2008, consider the below scenario:

In MS SQL Server 2008, you’re running a query that includes all the below mentioned clauses:
Inner join
Union all
Group by
The database query is using parallel execution plan.
You execute the query.

In the above scenario, you may face access violation. And, you receive the following error message:

Location: xbmp.cpp:2038
Expression: 0 != pxteBitmap
Msg 3624, Level 20, State 1, Line 2
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.

Furthermore, the mini-dump file is returned under the log folder of MS SQL Server 2008.


As sated in the above error message, this problem may have occurred due to either database corruption or a software bug. After corruption, SQL Server can not read the database and this behavior occurs.


Run DBCC CHECKDB utility to try fixing database corruption. If the database is severely corrupted, it may not work. In such cases, third-party applications are worth using.

The MS SQL Recovery applications are particularly designed to thoroughly scan whole SQL Server database and extract all damaged and inaccessible objects from it. They allow you to perform SQL Recovery on your own as they have simple and rich graphical user interface.

SQL Recovery software safely and successfully repairs damaged SQL Server database in all cases of corruption. It works well with Microsoft SQL Server 2008, 2005, and 2000. The software restores all database objects such as tables, reports, forms, macros, and more.

Choose Ruby On Rails For Simplicity In Programming
