In addition to page 9th for the boot page of the database, pages 8th through 173th are related to the SQLSERVER2008 internal system tables, and then from 174th page to No. 279 page are unassigned pages. Because the first page starts at 0, it's just 280 pages, which is exactly the same size as the database data files we see.See the previous
"suspect" because of an error encountered while accessing the page. Suspicious pages are identified in the suspect_pages table in the msdb database. You can restore multiple database pages immediately. The process is the same as the file restore process above. After the page is restored, all log file backups are also resumed. Each time you pass the log redo, the roll forward sets go one step further.Of course there is still a limit, page restore can only restore the data page. Page cannot be re
organized in extents.extents: Extents is logical units in the database. They is a combination of 8 data pages i.e. (KB) forms an extent. Extents can be of types, Mixed and Uniform. Mixed extents hold different types of pages like index, system, data etc (multiple objects). On the other hand, Uniform extents is dedicated to only one type (object).Pages: As we should know what type of data Pages can is stored in SQL Server, below mentioned is some of them:

extension. The space page is dedicated to the allocation and management of data spaces, including: PFS pages (page free space): Record whether a page is assigned, in a mixed or consistent extension, and how much space is available on the page; Gam page (Global allocation MAP) and Sgam page (secodary Global allocation map): Used to record the location of an idle extension or a mixed extension containing free pages.

rows inserted to perform the insert operation;3. Innodb_rows_updated: The number of rows updated to perform update operations;4. Innodb_rows_deleted: The number of rows deleted by performing the delete operation;by using the show status command to view the parameter values, it is easy to see whether the current database application is primarily an insert update or a query operation, and for the count of update operations, count the number of executions, whether a successful commit or a rollback
Original: SQL Server: Understanding IAM pagesIn previous articles, we discussed data pages, GAM and Sgam, and PFS pages. Today we will discuss the Index allocation Mapping (index Allocation Map:iam) page.In SQL Server 2005 and later versions, the allocation unit (allocation units) has the following three types:
IN_ROW_DATANBSP; for storage heap partitions or index partitions, heap and b-tree.

short period of time. In this case, to restore the service to normal as soon as possible, you usually need to perform the failover operation, force open the Standby database. Failover usually means a certain amount of data is lost, and the data loss problem is particularly prominent when Primary Database is RAC. Failover steps are as follows: 1. Stop the Application Log: SQL> recover managed standby database cancel; Media recovery complete.2 force stop the log application and execute the follow
Discovering the New World: The simplest way to crack SSL encrypted network data packets1. Introduction
I believe that the peers who can access this article will basically use WireShark, a popular network packet capture tool, to capture corresponding network packets for problem analysis or other things you know.
Generally, WireShark can be used to capture packets for analysis. However, there is a problem here: if you encounter network data encrypted by using SSL/TLS or other encryption means, we
