Easy Methods to solve recovery pending state in SQL Server Database

Users who are working with the SQL server database might have to face the problems with recovery pending state once because of the repetitive occurrence. 

So, to solve this kind of error this article will help to get rid off this state this article will help you to explains how to fix Database.

The database is a collection of data in a systematic way. Databases support manipulation and storage of data. Databases make easier management of data. 

Structured Query language (SQL) pronounced as “S-Q-L” or sometimes as “See-Quel” is basically the standard language for dealing with Relational Databases.

First, we have to understand all about the SQL Database states.

 

  • SQL Database States

 

If one or more of its key files are in the inconsistent state, an SQL database is considered to be damaged. The database is marked with different states depending on how severe the damage is. Check the following few states:

  • Online – The database will stay online and available if one of the data files has been damaged during a query or some other operation.
  • The suspect – If the transaction log is damaged and the recovery or rollback of a transaction is prevented from being completed, which could cause it to fail.
  • Recovery Pending – If the SQL Server understands that it is necessary to operate the recovery of the database, but something prevents it from starting. This is different from the state of SUSPECT because it can not be said that recovery will fail –it hasn’t just begun yet.

After understanding the SQL Database States then move towards the reason behind the Recovery Pending States:

Decoding where and what causes an error as important as finding a sure-shot alternative to it. A SQL database is marked in the state of Recovery Pending when recovery is required but can not be launched. This type of scenario mainly occurs when:

  1. The database is not shut down smoothly, i.e. at least one uncommitted transaction is active when the database is shut down and the log file is deleted.
  2. A user attempted to transfer the log files to a fresh drive to solve server performance problems, but in the process, the log files were corrupted.
  3. Database recovery can not be started due to a lack of memory or disk storage.

Causes of SQL Server Recovery Pending Error?

  • When Memory space is either full or more limited in Database partition.
  • Because of Hardware failure.
  • Corrupt log files.
  • While shutting down, Unfinished tasks or some actions were pending.
  • When you start the server without any time gap then there is a probability of occurrence of this error.

There are two types of solution for this error :

  1. Manual Methods
  2. Alternate Method

Manual Methods

Method 1. You have to perform a  repair by running the following SQL queries:

ALTER DATABASE [D-BName] SET EMERGENCY;

GO

ALTER DATABASE [D-BName] set single_user

GO

DBCC CHECKDB ([D-BName], REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS;

GO 

ALTER DATABASE [DB-Name] set multi_user

GO

  1. Emergency mode marks the database as READ ONLY and disables logging and system administrators are granted access.
  2. These steps will solve the corruption of the file and create the online database systematically.

Method 2. Mark the emergency database, detach and re-attach the primary database

  1. Execute the queries given below:

ALTER DATABASE [DB-Name] SET EMERGENCY;

ALTER DATABASE [DB-Name] set multi_user

EXEC sp_detach_db ‘[DB-Name]’

EXEC sp_attach_single_file_db @DBName = ‘[DB-Name]’, @physname = N'[mdf path]’

2. These commands will result in the server getting rid of the corrupt log and automatically building a fresh one.

Notice: You should guarantee that you have adequate backups of the database in question before starting any of these repair processes. If anything goes wrong, this is to have a failed-safe copy. Also, remember that these are extremely technical processes and if you are uncertain or do not have the adequate technical knowledge, you should not be performing them.

After discussing all the manual methods hope you will find the solution to the problem related to SQL Database.

Conclusion

We addressed the manual techniques of the “SQL server recovery pending” request that was most anticipated and there may be several factors that may cause an offline SQL database to go. Any DBA SQL user’s priority is to solve frequent SQL mistakes and get the database back on track as quickly as possible.
