Resolving Error 8909 in SQL Database

SQL Paging Technique – Formation of Pages: Being a relational database management system (RDBMS), Microsoft SQL Server works on large data amounts at every moment. For managing this vast amount of data, SQL makes use of paging technique. In this paging technique, data is split into logical & manageable pages that are sequentially related to each other. It is possible for you to traverse backward and forward on these pages.

SQL Database Corruption – Improper Functioning of Pages: Corruption is still an evident occurrence even with the best configured systems. SQL database are also not free from corruption or damage. They are also prone to corruption. Various uninvited and hard to evade reasons like abrupt system shutdown while SQL database is open, human errors, virus/Trojan infections etc can cause the damage. Due to the corruption issue in the database tables of MS SQL, the pages, created using the paging technique as talked above, might not function properly.

How to Fix Corrupt SQL Database? (Multiple IAM Pages Error 8947)

Global Allocation Page (GAM) of SQL Server File: An MS SQL Server file consists of various pages, which stores its allocation structures. One such page is the Global Allocation Page (GAM). It contains the information that is related to the allocated extents in that SQL Server file.

Index Allocation Map (IAM) Pages: Index Allocation Map (IAM) pages are the allocation pages that contain information of the extents that an index/table uses.

SQL Table Corruption Due to Multiple IAM Pages Error: Sometimes, you many encounter errors due to multiple IAM pages for a single object. Such types of errors indicate table corruption. The error you might encounter after such corruption in your SQL Server database table states:
Server: Msg 8947, Level 16, State 1
Table error: Multiple IAM pages for object ID O_ID, index ID I_ID contain allocations for the same interval. IAM pages P_ID1 and P_ID2.

Why Such Error Might Occur? If you are encountering the aforementioned error, then it implies that the IAM chain for the specified index has at least 2 IAM pages (P_ID1 & P_ID) covering the same GAM interval (interval is the file space used by the GAM page to map. It is approximately 4 GB). Every index, which is allocated from a GAM interval that has more than one extent, requires an IAM page for that specific GAM interval. For all GAM interval extents, an IAM page contains one bit for each extent. A set bit shows that the particular index is given to that index. A common reason for such multiple IAM pages error that you might be encountering can be hardware failure. SQL database recovery becomes necessary for you in this case.

How to Fix Damaged MDF File? You can perform the following methods for SQL database recovery:

• Replace Damaged Hardware: First of all, you must check if there is any issue related to hardware failure. For this, you can run hardware diagnostics and check your application, Windows & SQL Server error log. If such issue exists, replace the damaged hardware (if required).
• SQL Database Recovery from Backup: If you have a clean backup for your SQL database, then you can easily restore from it. But, if no such valid backup is there, then you can use a third-party tool.
• SQL Database Recovery using Third-party Tool: You can invest in an SQL MDF repair tool, which is an easy, efficient, safe and time-saving way to deal with the problem. One such powerful SQL database recovery tool is SysTools SQL Recovery software. It is a superior tool with a user-friendly interface and it employs advanced technology for efficient recovery and fast algorithms for quick MDF repair.

Fix Error 8936 in SQL Server

SQL Table Indexes (B-tree): Microsoft SQL Database Server supports B-tree indexes (table indexes) to provide quick query results. The pages of these B-tree indexes are called index nodes. The top node is termed as the root node, the middle nodes are called branch nodes and the bottom level nodes are denoted as the leaf nodes.

Corruption Issue in the Table Indexes: If these table indexes of your MS SQL Database Server get corrupted, then SQL Server might show error messages on your screen and you can even fail to access your database contents completely, which can cause severe harm to your work.

Use Backup to Restore Database Contents: In the aforementioned SQL corruption situation, a solution that you can easily try is to use your latest SQL database backup and restore the entire information that has been lost. To get back the lost information using the most recent backup that you had created for your SQL database, try the following methods:
• Run hardware diagnostics (this is because the problem could have occurred because of some hardware issues. Rectify the issues, if any).
• If your problem still persists, then try to restore your SQL Server database from a clean backup.
• If no clean backup is available, then run DBCC CHECKDB command to perceive the amount of corruption and examine the suggested repair clause. After that, you can run DBCC CHECKDB command with that suggested repair clause.
• If your SQL Server database is still in the corrupted state and no above methods work, then get a third-party SQL recovery tool.

Error 8936: Now, at times, this backup fails to restore the database contents. You can also come across the following error message (error 8936):
Server: Msg 8936, Level 16, State 1, Line 1
Table error: Object ID O_ID, index ID I_ID. B-tree chain linkage mismatch. P_ID1->next = P_ID2, but P_ID2->Prev = P_ID3.

Cause of Error 8936: This error 8936 can occur when your SQL Server finds a break in the logical page chain at any level of the B-tree. This can happen at any level of the B-tree including the root level and leaf level also.

8936 Error Fix Tool: In such a situation where you fail to restore the contents using the most recent backup and you are also encountering the above-mentioned error 8936, then it becomes essential for you to invest in a third-party recovery tool to fix error 8936. Using an outside software tool is in fact a smart, easy, quick, hassle-free and safe way to fix error 8936 in SQL Server and recover lost database contents. One such SQL Server repair tool is SysTools SQL Recovery software which you can easily use to solve error 8936.

How to Recover SQL Data from Suspect Mode?

SQL Server Management Studio (SSMS): At the time of SQL Server installation, the database users are given an integrated environment called SQL Server Management Studio (SSMS). The function of SSMS is to successfully configure, manage, develop and access all SQL server elements in a collaborative way. The importance of SSMS is thus obvious and therefore, any type of corruption in SSMS can result in inaccessibility of your SQL database contents like tables, queries, triggers, stored procedures, rules, user functions, etc. You might as well confront some error messages.

Suspect Error Showing in SQL Server Database: Now, in such aforementioned situation, it can happen that when you try to connect to your SQL Server database and try to open SSMS, then you might encounter an error message saying: “Database ‘msdb’ cannot be opened. It has been marked suspect.”

Why SQL Database Goes in Suspect Mode? One of the most plausible reasons behind the above mentioned error message is that your SQL Server database must have been suspected. This suspected mode of SQL database can occurs when one or both of the following conditions happen:
1. The error log file not matches with the database file
2. SQL database MDF file corrupts

SQL Server Database Inaccessibility: After such incidence, when you try to view the SQL Server application event log, you can find this entry: “The log scan number (152:284:1) passed to log scan in database ‘msdb’ is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during start up.” When you get such an error message, then your SQL Server database becomes totally inaccessible to you.

A Resolution: For solving this problem, you can try to use the inbuilt utility of SQL Server i.e. sp_resetstatus. Using this tool, you can change the status of SQL database and can get access to the database again. Here is a process that you can try yourself by just performing the following steps:
1) First, make sure that the device file is available.
2) Use sp_resetstatus (supplemental stored procedure) to reset the status of the suspected database.
• For SQL Server 6.0/6.5: If this is not done already then create procedure by executing the Instsupl.sql script (found in the Mssql\Install directory).
• For SQL Server 7.0 and later versions: Create it at installation by the inscat.sql script (found in Mssql\Install directory).
3) Run sp_resetstatus in master database for the suspect SQL database:
use master
go
exec sp_resetstatus your_database_name
4) Stop and start the SQL database Server again.
5) Confirm that the database is recovered and is available.
6) Run DBCC NEWALLOC, DBCC TEXTALL and DBCC CHECKDB.

Another Way to Solve the Trouble: In case you fail to recover SQL database from suspect mode using this inbuilt tool even after performing all the above steps, then there is another way to repair SQL database showing suspect error and that is by using third-party software tool to restore SQL Server. This is an easy, safe, effortless, efficient and time saving way for SQL Server recover suspect database. You just have to invest a small amount of money for an outside tool to easily recover SQL database from suspect mode. This will save your time, energy and effort greatly. If you get a low-priced tool that it would be an icing on the cake for you. One such easy-to-use, quick performing and efficient recovery solution is SysTools SQL Recovery software, which you can use to repair SQL database showing suspect error and to recover SQL database from suspect mode. Additional benefit to all these useful advantages is that SQL Recovery software is a cost-effective solution to restore SQL Server. The price of the Full Licensed Versions starts at ONLY $99 (for the Personal License).

How Can You Recover SQL User Database Contents from a “Suspect” Status? Here Is An Answer!

A possible scenario with SQL Database is - At startup, SQL Server tries to get a lock on the device file. If the device is used by some other process (say for example – the backup software) or if the file is missing, you might encounter this problem that your SQL database is in “Suspect Mode.” This can be a grave problem putting your crucial data at stake. To prevent such severe SQL data loss, there is a process that you can try yourself. Just follow the following steps:
1) Firstly, ensure that the device file is available.
2) Use supplemental stored procedure sp_resetstatus to reset the status of a suspect database.
For SQL Server versions 6.0 and 6.5 – if this is not done already, then create procedure by executing the Instsupl.sql script (found in the Mssql\Install directory).
For SQL 7.0 and later versions – Create it at installation by the inscat.sql script (found in Mssql\Install directory).
3) Run sp_resetstatus in the master database for the suspect SQL database:
use master
go
exec sp_resetstatus your_database_name
4) Stop and start SQL Server again.
5) Confirm that the database was recovered and is available.
6) Run DBCC NEWALLOC, DBCC TEXTALL and DBCC CHECKDB.
