Tips to resolve “IAM page P_ID1 is pointed...” Error message

IAM (Index Allocation Map) pages in SQL Server are primarily used to map the Extents in the database file. Every IAM page contains a header that signifies the beginning extent of the range of Extents mapped by a particular IAM. Corruption or damage in IAM header primarily results in an error message making all the data stored in the database inaccessible. One of the major causes for the IAM header corruption is damage of SQL Server database due to logical or physical scenarios. For comprehensive access of all the records stored in your database in header corruption situations, the best way is to restore the data from an updated database backup. However, if you have not maintained any database backup or backup itself is corrupt, then you will need to use advanced SQL Repair software.

Consider a practical scenario, where you manually updated the sysindex table in your SQL Server 2000 database. However, after the table is updated and you attempt to mount your database, you receive the below error message:

“IAM page P_ID1 is pointed to by the next pointer of IAM page P_ID2 object ID O_ID index ID I_ID but was not detected in the scan.”

Records stored in your database become inaccessible after the above error message appears. Additionally, the above error message pops up every time you attempt to mount your database.

Cause:

The root cause for occurrence of the above error message is IAM page (metadata entry) is unseen or is pointing to the next page in an IAM chain.

Resolution:

To resolve the above error message and access the database, you will need to use take below actions:

For corruption in IAM page due to hardware failure, run the hardware diagnostics and change the hardware components, if required. For logical corruption, run DBCC CHECKDB command (without repair clause). This will help you to identify the extent database corruption. Once the extent of corruption is identified, run DBCC CHECKDB command with appropriate repair clause.

But if in case, the DBCC CHECKDB with repair clause falls short to repair your database, then you will need to use third party SQL Recovery applications. These Repair SQL Database tools perform quick and risk free recovery of almost all SQL Server database components.

Tips to resolve “Unable to process index...” Error message

Filegroups in Microsoft SQL Server are primarily used to group database files to use them in an easy and simple way. A system administrator can create particular filegroups for each hard drive attached in the system and assign tables, indexes, text from a particular table to them. While these filegroups can be easily accessed, the possibilities of their corruption always remains. In such situations, the best way to access the data is by restoring it from an updated and valid backup. However, in case of no backup availability or backup failing short of restoring the desired information, then you will need to use advanced SQL Repair software that can completely repair your corrupted database and recover its components.

Consider a practical instance, where you receive the below error message when you attempt to open your SQL Server database:

“Unable to process index I_NAME of table O_NAME because filegroup F_NAME is invalid.”


Cause:

The root cause for the occurrence of the above error message is that filegroup Ids stored in the metadata for an index do not exist, so that index can not be checked.

Resolution:

Below are certain resolutions that enable you to resolve the above error message:

Error 2522 could be a result of hardware malfunction. In this case, you will need to check your computer system, Windows error logs, and SQL server. To resolve the hardware problem, you will need to swap the old hardware components with new hardware components.

Applying CHECKDB On Tempdb Cause Data Loss

The tempdb database is a global resource of MS SQL Server, which is available for all users that are connected to instance of Microsoft SQL Server. This database stores temporary user objects, internal objects that are designed by SQL Server Database Engine, row versions that are resulted by data alteration transactions and row version that are resulted by data alteration transactions for features. In some cases, when you try to repair a damaged tempdb database using CHECKDB command, SQL Server database corruption may occur. This behavior renders all of your mission-critical data inaccessible and thus you need to opt for SQL Recovery solutions to retrieve data.

In a practical scenario, when any of the database user raise attentions during process of SQL Server, you might come across any of the below error message:

Server: Msg 8946, Level 16, State 1, Line 1
Table Corrupt: Allocation page (1:253) has invalid IAM_PAGE page header values. Type is 1. Check type, object ID and page ID on the page.

Or

Server: Msg 8906, Level 16, State 1, Line 1
Page (1:253) in database ID 2 is allocated in the SGAM (1:3) and PFS (1:1), but was not allocated in any IAM. PFS flags 'IAM_PG MIXED_EXT ALLOCATED 0_PCT_FULL'.

Attains are raised by SQL Server clients while server is executing or performing commands, necessitating non-logged allocations in tempdb file like worktables for the cursors.

Cause

As stated in above error, this issue is caused by corruption to the SQL Server database table. When the database table gets damaged, an invalid value is written in header of IAM_PAGE page of table and the operating system could not identify table and gives you error messages.

Corruption to the SQL Server database table might occur due a number of reasons ranging from improper system shutdown to virus infection. When database corruption occurs, it neither accessed nor repaired through CHECKDB utility.

In such situations, you need to repair and restore the database using third-party SQL Repair applications to retrieve inaccessible or damaged data. The SQL Recovery tool perform systematic scan of affected database to ensure absolute recovery.

The software are quite easy to use as they have self-descriptive and interactive graphical user interface. SQL Repair is completely safe with these programs as they have read-only and non-destructive conduct.

Stellar Phoenix SQL Recovery is the most effective and advanced software that can handle most of the SQL Server database corruption scenarios. It supports Microsoft SQL Server 2008, 2005 and 2000. The software is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.

SQL Server Metadata Corruption After Importing Data From Excel File

In Microsoft SQL Server, you can import or export data through Import/Export Wizard. This wizard offers simplest way to create an Integration Services package, which copies data from a source to destination. The MS SQL Server Import/Export Wizard could copy data from and to a data source for which a native OLE DB provider or a managed .NET Framework data provider is available. Microsoft Excel is one such application. But sometimes, after importing data from Excel spreadsheet, the database may not be accessed. This behavior can occur due to corruption and lead to critical data loss situations. At this point, you need to opt for SQL Recovery solutions to retrieve business-critical data from damaged database.

In a practical scenario, when you try to open a SQL Server database after importing data from an Excel spreadsheet that was originally created using data from SQL resultset, following errors may occur and prevent you to access the database:

“The component has detected potential metadata corruption during validation.
Error at Update Counterparty Table with new counterparties [DTS.Pipeline]:
The package contains two objects with the duplicate name of 'output column'”

And

“It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?”

When this issue occurs, MS SQL Server database become inaccessible. In order to sort out this problem, you need to find out the cause of this issue and go for SQL Repair by resolving it.

Root of the issue

As stated in above error message, this problem occurs due to metadata corruption in SQL Server database. SQL Server use a number of metadata for effective management of database. The metadata are used for easily accessing data from database. When they gets damaged, SQL Server can not find the required data and thus you come across data loss situations.

To retrieve data in such scenario, repair and restore damaged database through third party SQL Recovery applications. These software are particularly designed to thoroughly scan the affected database and retrieve all of its damaged and inaccessible objects such as stored procedures, triggers, tables, reports and forms. These tools are completely safe and easy to perform SQL Repair in all database corruption circumstances.

SQL Recovery is the best ever made and the most advanced application that repairs and restores all of the SQL Server database objects. It supports recovery from Microsoft SQL Server 2008, 2005 and 2000. This software is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.
