Each SQL Server transaction log file is divided into several smaller segments, known as virtual log files. These files are the units of truncation for transaction log. When the virtual log file no longer holds log records for active database transactions, it could be truncated and the space becomes available to log novel transactions.
The minimum size of a virtual file is 256 KB and for transaction log file, it is 512 KB, which gives two 256 KB virtual log files. The size and number of virtual log files in the transaction log increase as the size of log file raises. A small log file could have a number of small virtual files.
MS SQL Server tries to evade having several small virtual log files. The number of these files grows much more gradually than the size and it is not good for the SQL Server. A large number of virtual files could make the database recovery very time consuming and complicated.
If the number of transaction log files increase, then during rollback or recovery, a KILL PSID gets issued automatically and the rollback process gets terminated. The KILL halts the user process based upon the system process ID (SPID).
In such circumstances, the recovery or rollback fails to complete and the database remains in corrupted state. The data stored on the MDF file can not be accessed and you may face the catastrophic nightmare of data loss.
But there is an other way that can save your data and it is the SQL recovery. The SQL recovery is the process of repairing damaged MDF file using some third party tools. These tools are known as MDF recovery software.
MDF recovery software are the easiest and quickest solution to carry out absolute SQL repair in all cases of MDF corruption. These software performs MDF repair by thoroughly scanning the damaged file and then extracting all of the data from it.
To do SQL recovery using these software does not demand any sound technical skills as the software are very easy to use and come equipped with interactive user interface.
Though, SQL repair software are very helpful in carrying out MDF repair but you should always bear in mind that use of wrong application could ruin the situation. Thus, it is really important to use a powerful and trusted MDF recovery software to ensure complete extraction of your data.
Stellar Phoenix SQL Database Recovery software is the best ever made and the most advanced MDF recovery software which allows you to have SQL repair in all cases of corruption. With the interactive and cool looking user interface, this software won’t let you feel the lack of technical knowledge.
