If you have your transaction logs, you will be able to recover to the transaction log prior to the problem, which might mean a small amount of data loss. If all your transaction logs are available, you might be able to recover to the exact point of the data change, but this requires a third-party tool to allow you to read the current transaction log (as well as possibly your transaction log backups) and step through each individual transaction. SQL Server does not provide any native tools for reading the transaction log. If you decide to employ such a method, only experienced DBAs who know what they are doing should use the tool; otherwise, you might incur even more damage to your data. This example illustrates how important it is to make frequent transaction log backups. Unless you do not care about your business s data, transaction logs could mean the difference between surviving human errors or losing crucial data you might never see again.

The command needs to be initialized with the context connection and the SQL statement you want to execute. Once this is done, you can call one of the Execute methods to execute the command. For example, to execute a simple SELECT statement, getting the data into a SqlDataReader, you d use code like this: using (SqlConnection cn = new SqlConnection("context connection = true")) { cn.Open(); SqlCommand cmd = new SqlCommand("SELECT * FROM Person.Address", cn); SqlDataReader reader = cmd.ExecuteReader(); Once you have the reader, you can use it to iterate one row at a time through a resultset of data returned by a query. SqlDataReaders are always forward-only and read-only, so you can t go back to a row that you ve already read, and you can t modify any of the data (we ll look at a way to get around these problems shortly). When the reader is first opened, it points to the beginning of the data (BOF), so you need to move to the first row before any data can be accessed. You do this by calling the Read method, which moves the reader to the next row and returns false if there are no more rows or true if there is still more data to be read. To iterate through the whole of the data, you therefore need to call Read until it returns false: while (rdr.Read()) { // Access current row here

This is the part of the chapter where I think I m legally obligated to give you a quick review of TCP/IP network addressing, and how that s used to define a subnet If you know this stuff like the back of your hand already, go ahead and skip past this (I won t be offended, honest) Each TCP/IP address is made up of four sections or octets, so called because IP addresses are actually 32-bit binary numbers that get converted to four decimal numbers to make it easier for humans to read This is called dotted decimal notation, and creates the familiar 1921681101 IP addresses that you re probably quite familiar with Every IP address is broken up into two parts: the network address and the host address.

If there is any one statement I hear more than any other when it comes to availability from customers, it is, I cannot tolerate any data loss. Not only in 9.9 times out of 10 is this not true, but in any kind of availability technology, you should count on some data loss. Although this is a topic that should arguably be introduced after discussing each technology individually, your data loss is directly related to your last backup. Look at the examples shown earlier: For the full backup, could you tolerate losing that 14 hours of data Is that within your tolerance allowed in your SLAs Do you have a method of reconstructing the 14 hours of data from another system even if it will take time These are the types of questions you need to be asking yourself as you are devising your backup and restore plans as they relate to your SLAs. A more robust and frequent backup strategy leads to less data loss in a recovery. The rate of your data change will dictate this to some degree as well. If your data is barely changing on an hourly or daily basis, less frequent backups can be absolutely appropriate. To say you need to do transaction log backups every five minutes when you have only ten records inserted an hour might be overkill . . . or it might not be. However, if you are updating, inserting, or changing thousands of records per minute, your exposure with less frequent backups is glaring: a minute s worth of data could mean thousands of dollars to the business.
