How to Troubleshoot Mac USB IssuesIn Feburary 2016 04,

In Feburary 2016 04,
Check that the USB device is connected to the appropriate jack. There is a USB jack in the back of most keyboards, but it often only works with a mouse.
Unplug any USB devices and wait a few moments before reconnecting them. You can often fix problems with your USB keyboard and mouse by using this method. Try restarting your computer if the malfunction persists after you reconnect the USB device.
Test your USB peripherals in another computer. If the problem exists in the second computer, you may need to have the device serviced or look for an updated version of the firmware that supports your USB item. Check the manufacturer's website for these updates.
Try different devices in the same USB port. For example, if your mouse if behaving strangely, see whether an external drive or an iPod is able to connect to the computer via that USB port.
Disconnect any USB hubs that you're using and connect each device one at a time to your computer. You need to troubleshoot the devices individually to find out whether the USB hub or the one of the devices is causing the problem. Be sure to test each peripheral with a working USB cable.
Reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) on your computer. Turn off your computer, then restart it and immediately press and hold the 'Command,' 'Option,' 'P' and 'R' keys on the keyboard. Release the keys after you hear the startup chime for the third time and your computer should boot normally.
Consider reinstalling the operating system after clearing your computer's hard drive. Be sure to back up all of your data before you erase the disc. You may also want to bring the computer to a Mac service center and have the logic board examined.

Advantages of SQL Server Over OracleIn Feburary 2016 04,

In Feburary 2016 04,
According to customer case studies, a database administrator can manage over 65 critical SQL server databases, while Oracle requires one administrator per 15 critical databases. Critical databases can be defined as systems vital to the operation of a company. With all databases and sub-databases included in the study, one Microsoft SQL database administrator can manage 214 databases, while Oracle handles only 31 databases per administrator.
Problem Resolution and Tuning
Alinean claims that Microsoft SQL Server administrators spend less time problem solving and tuning than Oracle database administrators. On average, Oracle administrators spend 33 percent of their time on these tasks, while SQL server administrators only spend 18 percent.
Installation and Configuration
SQL Server is said to be more user friendly and less time-consuming to install than Oracle. SQL Server database administrators spend 1.5 hours on average setting up a new database server, while the same task takes Oracle administrators approximately six hours.
Lower Administration Costs
Companies utilizing SQL Server spend less money on administration per database than those who run on Oracle, according to Alinean's study.
Better Security
Microsoft claims that SQL Server comes with better security options than Oracle. Oracle is said to only provide basic security in standard and enterprise editions, and offers expensive add-on security only with its enterprise edition. On the other hand, SQL Server includes extra security features in its work group, standard and enterprise editions.
More Features
SQL Server has advanced and integrated enterprise features such as advanced compression, data mining, partitioning, OLAP, enterprise reporting and spatial included in the package, while Oracle users have to purchase these as add-ons.
