Troubleshooting “SQL Server Database Is In Recovery Pending State”


Overview

Users of SQL Server Database must be aware of Recovery states, that occurs when there is unintentional dropped SQL table or any other components that needs to be restored. The SQL Server Database is in recovery pending state at situations like restart of SQL Server, offline & online state of database or while restoring database from a backup. However, if there is any issue during this recovery process, error can be Continue reading “Troubleshooting “SQL Server Database Is In Recovery Pending State””

SQL Server Transaction Log Backup Failing (Error 22029)


A Transaction Log is a file that contains all the records of transactions and the database modifications made by each transaction in SQL Server database. The log file plays a very important part of SQL Server database when it comes to disaster recovery and it should not be in corrupted state. There are several types of errors we came across while using SQL Server and one of the most common error is Failure in SQL Server Transaction Log or Error 22029. This page will be discussing about the same error in details.

SQL Server Transaction Log Backup Failing

Why It Occurs?

SQL Server Error 22029

This error in associated with the maintenance plan of the transaction log back up or maintenance plan options for the database in SQL Server.

There are many reasons why the above error in SQL Server occurs-

  1. The SQL Server transaction log backup error 22029 may be seen if your database maintenance plan is trying to make a transaction log backup of a database that is offline.
  2. It may occur when you try to create transaction log backup and when the database is using the simple recovery model.
  3. It may occur if you select the master database and you choose backup the transaction log as part of the maintenance plan option.
  4. This error may also be seen if the string for the target folder (where the database backup will be stored or the one used for transaction log backup or one used for reports) in the maintenance plan contains “-S”
  5. It may happen if you have less disk space for the transaction log backup.
  6. If the multiple databases are backed up in a single maintenance plan, this error might show up.
  7. In addition, it may occur if you have no right access permissions or authority. Example- the SQL agent does not have write access to the file storing the database backups.

How It Can Be Resolved?

One thing that should be kept in mind while creating maintenance tasks is to check the “write report to a text file in directory” so that all the details of whatever happening during the maintenance task is seen, especially when there is any error.

Database Maintenance Plan

  1. The reason why the first error occurs can be solved by connecting the database to the server. So that, the log of that database can be backed up successfully with the maintenance plan as the database is online.
  2. While creating the maintenance plan for transaction log backup under simple recovery model, we may find error. Why is it so?
    The simple recovery gives the simplest form of backup and restore. It supports both database and file backups but does not support log backups. The absence of log backups simplifies managing backup and restore.

    Tips: The simple recovery model is not appropriate for systems where loss of recent changes is unacceptable. In such cases, full recovery model is preferred.

    We should never run a transaction log backup on a database in the Simple Recovery model. Even though there is option to select all databases, we can select either database that are not in Simple Recovery model or change the database to the Full or Bulk-logged Recovery models to avoid this error. This problem has been fixed in SQL Server 2005 as the databases in simple recovery are ignored automatically.

  3. The third error says we cannot select master database and choose backup of transaction log because only full database backups of master database are allowed. Hence, we can create a separate maintenance plan for master database and not backup the transaction log or set master database to Full recovery and do transaction log backup.
  4. To solve the fourth error, we will not use strings that contain “-S” for a directory path. It only occurs on named instances of SQL Server 2000.
  5. The problem with less storage can be solved by allocating more disk space.
  6. If the error occurred due to sixth reason, then we can select a single or some databases while back up and keep in mind the type of recovery models with respect to transaction log backup.
  7. To perform transaction log backup of the database, we need to configure MS SQL Server to run under a user account that has administrator privileges to the machine.

Transaction Log Corruption and Backup In SQL Server


Introduction

Corruption of SQL Server transaction log files is complicated because its consequences aren’t major except for the fact that they result in the failure of backups. However, that as well is a necessary task to be performed by every server admin for business continuity and thus, must not be ignored.

I/O subsystem is the culprit in most cases of Transaction Log file corruption just like a data file. Till the time this damage has been caused to the active portion of the file – required by SQL Server for some reason – it is possible that the cause remains unknown for a long duration. This may result in a major disturbance because corruption, which is undiscovered, will take equal amount of time in being rectified too, which may make the condition much worse too in the meantime. However, SQL Server has no way of detecting the corruption anyway before any kinds of consequences are surfaced. In order to detect the damage, the server will have to process the complete log file and that too particularly the active parts.

DBCC CHECKDB is a built in utility provided for examining database integrity in SQL Server. Continue reading “Transaction Log Corruption and Backup In SQL Server”

Get all Database Job History then Send Email


***************************************************Introduction********************************************************

Today i will Dessecus how to Get all Database job history then Send Email to The Technical Support “job History Report” then i will delete this log history

Get Daatabase job history

select * from msdb.dbo.sysjobs

Job history

Get database job Step history

select * from msdb.dbo.sysjobhistory

Hob Step History

Now i will make join between msdb.dbo.sysjobhistory and msdb.dbo.sysjobs by Job_ID  and i will  Convert the job tun Date time because if you select it without convert you will sedd the Data Formate “20121224” so i will convert it , also i have column name “Run_Status” this Column return 0 or 1 { 0 = the job is Failed , 1 = The job is Success } so i will make Case when on this Column this Script you can use it for to ways

1- job Failed history report

2- job Success history Report

but i will write now ho to get job all history Failed and Success

How to Check backup log /and How to Delete backup log


introduction

Today i will explain how to monitor your backup is Saved on or no also How to Delete the old backup history from the log

How to Check your Backup log or your backup history

we can Check the backup history by this way but before this step i need from you to Create Databae “backupTest” and take backup from it with 3 types Full,DIFF,LOG

select Database_name,backup_start_date,backup_finish_date,type from msdb.dbo.backupset

you can select all Column (*) to see all information

but i will customize it to help you how to check the FULL backup , DiFF backup , Log backup

********************************Check FULL abckup history************************************

SELECT database_name,backup_start_date,type,recovery_model,server_name,machine_name,is_password_protected

FROM msdb.dbo.backupset where Type=‘D’ ORDER BY backup_set_id DESC

GO

********************************Check DIFF abckup history************************************

SELECT database_name,backup_start_date,type,recovery_model,server_name,machine_name,is_password_protected

FROM msdb.dbo.backupset where Type=‘i’

ORDER BY backup_set_id DESC

********************************Check LOG abckup history************************************

SELECT

database_name,backup_start_date,type,recovery_model,server_name,machine_name,is_password_protected

FROM msdb.dbo.backupset where Type=‘L’

ORDER BY backup_set_id DESC

GO

How to Delete your backup history:-

we can make delete for all backup history for any database by this Code

exec MSDB.DBO.sp_delete_database_backuphistory ‘Database name’

So this Code Delete history to the backup but for one database one by one so i will make Cursore to loop on all Server to get all database name then Delete the backup history for all Database

set ANSI_NULLSON

set QUOTED_IDENTIFIERON

go

Create PROC[dbo].DeletebackupHistory

AS

BEGIN

DECLARE @DB Nvarchar(50)

DECLARE GetDB CURSOR FOR

Select Name from Sys.Databases Where database_id> 4 and state_desc=‘ONLINE’

OPEN GetDB

FETCH NEXT FROM GetDB INTO @DB

WHILE @@FETCH_STATUS= 0

BEGIN

—-Delete backup history

exec MSDB.DBO.sp_delete_database_backuphistory @db

——————————-

FETCH NEXT FROM GetDB

INTO @DB

END— FETCH WHILE

CLOSE GetDB

DEALLOCATE GetDB

END
