How to Bring Database Online From in Recovery Mode SQL Server?

If you are looking for a solution to fix how to bring database Online from in recovery mode SQL Server then this post is right for you. In this post,?we are going to discuss the main reasons for this issue. Also, we tried to explain how to troubleshoot and fix the problem using manual and automated tools.?

Types of States in SQL Server Database?

In this section, we will discuss different types of states in SQL Server databases. In SQL Server database state represents the operational status, accessibility, and recovery status of the current database. It also checks whether it performs read-and-write operations, recovery and restoration processes, and the inconsistent state of the SQL database.?

If the user wants to check the current status of their SQL database by selecting the state_desc column available in the sys. databases cart.?

SELECT name, state_desc FROM sys.databases;        

Using this command users can easily check the current status of any particular database, and use the DATABASEPROPERTYEX function with the variable “status” property.?

SELECT DATABASEPROPERTYEX ('DBLogTest', 'status');        

Online State: In SQL Server Database if the user wants how to bring database online from restoring state then an Online state is a state where the SQL Server is completely available and fully accessed for all the SQL operations without any hindrance. In Online State, the Default filegroup is online for use, but the undo state of database recovery still needs to be completed.?

Offline State: In the SQL Server database an Offline state is a state where the SQL Server is inaccessible to the SQL users. This state is helpful when users try to move the database files to a new drive or current users from the availability of the database.?

Follow this command to set the database into Offline state.

ALTER Database DBLogTest SET OFFLINE;?

GO

Recovery State: ?In the SQL Server database, a recovery state exists when you try the? SQL database to execute?crash recovery, data corruption, and transaction recovery to ensure that the SQL Server database is consistent with the SQL data and acts in a normal usable state. The SQL database becomes online accessible after the successful completion of the recovery process.?

Restoring State: A SQL database gets into a restoring state when the SQL Server undergoes a recovery process from an SQL backup. This occurs when users restore a complete database backup. It is inaccessible to the users when it moves into the restoring state. If users follow the proper steps then they can easily know how to bring database online from restoring state.?

Recovery Pending: This state occurs when the SQL database moves into the recovery process but due to certain reasons?it is currently not available to the users.?

Suspect State: In the suspect state the database is inaccessible to the users due to database file corruption, and inadequate disk storage. It's preventing normal operations in the database from doing their regular work.?

Use this command to check the database's integrity.?

DBCC CHECKDB ('database_name', REPAIR_ALLOW_DATA_LOSS)        

Emergency State: In SQL Server the emergency state allows SQL users to access the database in suspect and recovery pending state. This state is generally set by the SQL admin when it wants to repair and restore the database. It allows only READ_ONLY mode to the other users and limits?the access to the non-admin users.?

Use this command to set the database in Emergency mode

ALTER Database DBLogTest SET EMERGENCY;        

In the coming section, we discuss the reasons behind how to bring the database online from in recovery mode SQL Server.

Potential Reasons for SQL Server Stuck in Recovery Mode.

SQL Servers stuck are in recovery mode due to the following reasons and if the user wants to how to bring database online from in recovery mode SQL Server.

Hardware Problems: Sometimes, hardware failures such as disk controller, hard disk, and other components can cause database corruption and loss of data due to which SQL Server stocks in recovery mode during initial steps.?

Corrupt SQL Database Files: Because of damage and corruption in SQL primary and secondary i.e. (MDF and NDF) or SQL transactional log files can hinder the recovery process which may lead to the SQL Server remaining in recovery mode.

Software Bugs: Bugs and faults in SQL Server database software can cause severe damage to database files that may stop the process and lead to SQL Server remaining in recovery mode.?

Large SQL Transactions Log Files: Sometimes, the extended size of the transactions log files or taking a lot of storage space to hold the files, can prolong the process and lead to the database remaining in recovery mode.?

Inadequate SQL Resources: In case of SQL Server instance is executing with a lack of resources such as storage, CPU processing, etc. Due to this process is slowed down or may lead to stuck in?

Human Errors: Because of the deletion or changes in the SQL database files, System settings or storage errors can cause the database to remain in recovery mode.?

2. Now, add and open the MDF file on the software.
3. Select the scan mode according to the requirement of the file.
4. Choose the export option such as SQL Server Compatible Script, CSV file format, and SQL Server Database.?
5. Now, hit the Export button and save the file on your computer.?

Top Checklist for How to Bring Database Online from in Recovery Mode SQL Server?

Identify All Error Logs in SQL Server: If there is any kind of error present in the SQL Server related to the state error, it must be checked first. We can do this with SSMS utility to identify the main cause of the error.

Check SQL Error Logs: To fix the recovery process, start by checking the SQL error logs for any message related to the recovery problem. This will help the user to identify the cause of the problem.?

Enable Adequate Time: SQL Server recovery procedure can take a lot of time, specifically for large database files and extensive data recovery. Patience is the key during the entire process, as allowing the SQL server to finish the recovery.?

Evaluate Progress: To check the progress of the recovery procedure by executing the following command in SQL Server Management Studio (SSMS) opposite master database;?

SELECT session_id, command, blocking_session_id, wait_type, wait_time, wait_resource FROM sys.dm_exec_requests WHERE command = 'DB STARTUP';        

This command shows the sessions that are presently running the database operations, including SQL recovery mode.?

Check SQL Database State: To validate the SQL database status, run the following command on the master database.?

SELECT name, state_desc FROM sys.databases WHERE name = 'YourDatabaseName'; Replace 'YourDatabaseName' with the name of your database. If the state_desc column shows 'RECOVERY_PENDING' or 'RECOVERY_IN_PROGRESS',        

Execute Repair: If the user's database recovers fails or becomes unavailable, the user can try to repair it using DBCC CHECKDB commands. However, the chance of data loss is there.?

Restore From Backup: In case, all the solutions fail to fix the issue then try to recover using the backup. It can easily know how to bring database online from in recovery mode SQL Server.?

Customer Care Support: In case, the user is still not able to solve the issue on your own, then try to contact Microsoft Support or the user database admin for further help and guidance.?
