Disk Or Network Error Message In MS Access

Randomly opening and closing the Access database in multi user environment can result as database corruption. Once the data is corrupted, it becomes inaccessible to every user connected on the network. In such situations, if the user has not maintained a complete backup of the lost data, then he needs to use effective Access Repair application to repair and restore the Access database.

As an instance of the above issue, when a user connected to a local area network (LAN) attempts to view a data file that is located on a network drive, he encounters the below error message: “Disk or Network Error”

This error message occurs every time user attempts to open the data file. The main cause of the above error message is that the name of the Access file in the file path consists of Double-Byte Character Set (DBCS) characters. Another major reason for the above error message can be faulty hardware component such as hard drive, network cable etc. The above error message appears again and again each time the user wants to access that file. Multiple occurrence of this error message results in Access database corruption.

To resolve the error message and to access the data file, the user needs to follow these steps:

• He needs to remove the double-byte characters from the file name. To do so, the user either should rename the relevant file name or move the file to a folder that consists of only single byte characters.

• In case of faulty hardware, the user should replace the hardware component with a new one.

If the above error persists even after following the above measures, it results in Access database corruption. In such scenarios, the user needs to repair the Access database by using an inbuilt tool known as Compact and Repair utility. But if this inbuilt utility fails to repair and restore the Access database, then the user needs to use third party Access Repair applications. Such Access Database Repair applications repair and restore the affected Access database by incorporating influential and powerful scanning algorithms.

Stellar Phoenix access recovery Software ensures complete and orderly Access Database Repair. It can restore and Repair Access objects like tables, queries, macro, module, forms and report. It also recovers fields like Hyperlink, AutoNumber, OLE object and Yes/No. It supports Access 2007, 2003, 2002(XP) and 2000. It is compatible with Windows Vista, XP, 2000 and NT.

Database Archiving As A Vital Factor Of Information Lifecycle Management (ilm)

Information lifecycle management (ILM) has evolved to define an approach for data management and cost-effective storage medium over time, based on its value for business. Database archiving is also pivotal for ILM as it helps eliminate redundant data stored in the production server. Data kept in storage networks have a defined lifecycle which is associated with the way information travels through an organization from its beginning till its removal. Data is usually stored in structured relational databases, semi-structured databases (emails), and unstructured databases (documents and graphics). Huge databases pose some very definite problems for information lifecycle management.

Large enterprises today are neck-deep with information flooded from all directions in their respective storage mediums. Unused data is continually eating up resources, and gobbling up the organization’s profits. Megabytes gave way to gigabytes, gigabytes have acceded to terabytes, and in the near future, terabytes is sure to escalate to petabytes. The data is growing relentlessly with organizations waking up to the reality of data explosion. The latest data retention clauses for pharmaceutical companies are at least 20 years while nuclear facilities will have to hoard data for 50 years. Database archiving helps in reducing costs, retaining data, and also aids in complying with regulation procedures.

Database archiving plays an important role in implementing ILM in a complex relational database. Removal of rarely accessed data releases the processing power and improves application performance and efficiency. Purging of irrelevant data also helps in implementation of new applications in the present hardware itself, without adding to any or little overheads. Additionally scheduled archiving releases a huge amount of disk space which is then utilized for other uses saving millions in software or hardware upgrades. Archiving provides a worthwhile solution to the data explosion problem, while cutting on the Total Cost of Ownership (TCO).

A comprehensive archiving solution archives data from a plethora of platforms. It is also expected to ensure referential integrity and help in restoring information when needed especially for business and compliance requirements. Additionally, the archiving solution should enable data retention in cost-effective mediums like a near-line on a file server, or disk-based WORM (Write-once-read-many type devices).

Implementing archiving strategies for databases is crucial for the efficiency of information lifecycle management.

Resolving 8905 Error Message In SQL

DBCC (Database Console Commands) commands are vital for T-SQL (Transact-SQL) as they check logical and physical integrity of all objects under a selected database. The DBCC CHECKDB statement enables the user to catch and repair all the possible errors that can occur while accessing a SQL database. A DBCC CHECKDB command uses three parameters (repair_allow_data_loss, repair fast and repair rebuild) to perform absolute repair of the SQL database. However, there are certain issues that the DBCC CHECKDB command can not resolve. These issues make the data saved in the SQL database inaccessible. To access the SQL database and perform complete repair and restoration, if the database user has not created any back up, an efficient SQL Repair tool is required.

While shrinking the SQL database using DBCC SHRINKDATABASE command, the database user may encounter the following error message:
“Server: Msg 8905, Level 16, State 1, Line 1
Extent (1:192) in database ID 10 is marked allocated in the GAM, but no SGAM or IAM has allocated it.”

After the above error message appears, the extent in the SQL database becomes inaccessible. An extent in SQL database is the basic unit in which space is allocated to tables and indexes. These types of error messages are normally accompanied with one or more occurrences of error 8909. Furthermore, these errors are mainly caused in multi processor environments. The main cause of the above error message is that database user is using the shrink database and reindexing operation simultaneously. To prevent the SQL database from the above issue, the database user needs to reschedule the operations to execute at different times and turn off the Auto shrink option for that particular database.

To resolve the above issue and access the SQL database, the user needs to execute DBCC CHECKDB command with repair_allow_data_loss option. This command performs complete repair and also includes allocation and de-allocation of pages for rectifying allocation errors and deletion of corrupted text. However, this repair utility can also result in loss of data. In such scenarios, the user needs to recover the lost data by using effective SQL database recovery application. Such SQL Recovery software ensure complete repair and recovery of lost SQL database components by employing advanced and powerful scanning algorithms.

Stellar Phoenix SQL recovery is an excellent SQL Recovery application that performs complete and orderly recovery of SQL objects. It provides interactive and intuitive graphical user interface. It is compatible with MS SQL Server 2005 and MS SQL Server 2000. It also recovers and restores the back up files of MS SQL Server.

“broken Reference To The File…” Error In MS Access

An error message in MS Access database can be caused due to importing an incompatible or invalid database component, operating system corruption, virus infection etc. This error message does not allow the user to further access the database. In such situations, the user needs to recover the Access database from the latest backup. However, if the user has not created any backup of the inaccessible Access database, the user can repair and restore the Access database by using advanced Access Repair utilities.

As a practical scenario, when the user attempts to import a database component like form from Access 2003 to Access 2007, he encounters the below error message:
“Your Microsoft Access database or project contains a missing or broken reference to the file version ”
here signifies the name of the .dll or .tib file
here signifies the version number of the .dll or .tib file

After the above error message appears, the Access database closes unexpectedly. When the user attempts to remount the Access database, he is unable to do so. Furthermore, the Access database becomes inaccessible and unmountable. Two main reasons for the occurrence of the above error message are:

• The form in the source Access database contains a reference to a DLL (.dll- Dynamic Link Library) or to a type library (.tlb).
• The DLL (.dll) or the type library (.tlb) does not exist in the same location on the source computer.

To resolve the above issue and access the database, the user needs to repair or recreate the corrupted database relationships. Repairing a database relationship creates a reference of the file name to a library or an updated version of that library. In small Access database, the user can easily and quickly recreate all the relationships. But in case of large Access database, the user can not recreate all the database relationships again. In such scenarios, the user needs to perform repair by using powerful access repair application. The repair software performs MDB repair without modifying the original contents of the Access database. Such repair applications use influential scanning methods to repair the corrupted Access database.

Stellar Phoenix access recovery is the most powerful Access Repair application. It can easily recover Access database relationships. It can restore and Repair Access components like tables, queries, macros, modules, forms and reports. It supports Access 2007, 2003, 2002(XP) and 2000. It is compatible with Windows Vista, XP, 2003, 2000 and NT.

Exporting Data From Databases Into Simpler Formats

Data stored in modern databases in the form of records, tables, views and queries is saved in binary formats that are hard to print, view or show on a presentation without a conversion. Databases are optimized for sheer speed, and are difficult to review, print or publish underlying data structures and queries. But what if you have a database that you want to show to someone without knowledge of database formats, and even without having the database itself installed? Exporting data from a database into a simpler format such as plain text, XML or HTML is usually required. And if your database has structures more complex than linear data records, you’ll have a really hard time. Unless you employ a proper data conversion tool, that is!

Extract and export data from databases in a number of formats automatically. FlySpeed Data Export exports data directly from numerous databases such as Oracle, MySQL, MS SQL Server, and supports PostgreSQL, Firebird, DB2, Sybase, Informix, dBASE and numerous other databases via ODBC or OLE DB.
