The database storage is managed by two major storage engines- MyISAM and InnoDB. Both these engines offer advanced features to manage the database. MySQL database management commands include ‘Delete’ operation. This statement enables you to delete selected or all rows from a table. It also provides the total number of rows that are deleted. Howerver, under some circumstances, the MySQL database may get corrupted after this operation and put you in need of <a href="http://www.rsdatabaserecovery.com/mysql-recovery-software.html">MySQL recovery</a> solutions. <br /><br />The first and foremost thing for the edit operations on your MySQL database is that you must have sufficient privileges to do it. Delete operation on the database is pretty safe if you are doing it properly. But there are some situations where your MySQL database may give you strange errors when you attempt to access the database after running Delete statement. This behavior makes your significant data inaccessible and lead to critical data loss. <br /><br />For a real life example of this problem with your MySQL database, you may encounter the below error message when you run the Delete query on your database:<br /><br />“InnoDB: Failing assertion: fil_page_get_type(page) == FIL_PAGE_TYPE_BLOB...”<br /><br />The delete statment fails to work after this error message. Along with that, all the records of MySQL table become unusable. In such situations, you have to find out the reason of this issue and fix it using <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">MySQL repair</a> solutions. <br /><br />Root of the problem:<br /><br />You may encounter this behavior of MySQL database management system due to any of the following reasons:<br /><br />• The MySQL server installation is faulty. <br />• There is a buggy BLOB handling in MySQL database. <br /><br />Solution:<br /><br />In order to sort out this problem with MySQL database, you can try the following MySQL recovery solutions:<br /><br />• Run CHECK TABLE and REPAIR TABLE commands on affected table. <br />• Restore database from valid backup. <br />• Use third party MySQL database repair applications. <br /><br />The commercial software are very useful in all corruption scenarios. They help you repair and restore corrupted database extremely effectively. Such applications restore all database objects, including tables, reports, forms, stored procedures, and triggers. They works well with databases created using both InnoDB and MyISAM storage engines. <br /><br /><br />1. Run check table on corrupt table<br />2. Then run repair table command on that table<br />3. Try and re-run the Delete command. <br /><br />There is still a slight possibility that your table still remains corrupted after following the above steps. For successful and complete repairing of table, you will need to use an advanced MySQL Database Repair software. Such tools use powerful repairing methods to provide absolute MySQL Repair in all situations. With interactive user-interface, these tools are easy-to-understand without any prior technical knowledge.

MySQL tables are very easy to manage and access. Tables enable you to store your significant data in orderly fashion (in form of rows and columns). However, under some situations, you may run across performance issues with the MySQL tables. In such situations, you need to go for <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">MySQL Repair</a> solutions. <br /><br />You have to always specify the type of table before you enter actual records in the table. But there are some situations where you may find the decreased performance of queries and errors when you try to access the tables. This behavior most probably occurs due to corruption to the table. Table corruption may be the outcome of unexpected system shutdown, application malfunction, virus infection, hard drive errors, and unexpected locking of the tables. <br /><br />For a real life example of this problem with MySQL database table, you may encounter the following error message while accessing a MySQL table:<br /><br />“Record was already deleted (or record file crashed)”<br /><br />This error occurs even if the record is there, but MySQL application is unable to recognize it. At this point, you have to find out the main cause of the problem and then repair MySQL database by fixing it. <br /><br />Root of the problem:<br /><br />The major reason of this problem is corruption of the MySQL table. Corruption occurs due to virus infection, application malfunction, improper system shutdown, and other similar reasons. <br /><br />Resolution:<br /><br />Try any of the below MySQL repair solutions to fix this problem:<br /><br />• Log into the MySQL as an administrator. <br />• Use the CHECK TABLE command to make sure the problem is caused by table corruption. <br />• If corruption is reported, then use REPAIR TABLE command, which is an inbuilt solution to <a href="http://www.rsdatabaserecovery.com/">repair MySQL database</a>. <br />• If you fail to recover MySQL database using any of the above methods, then you have to restore data from an updated backup. <br />• In case, backup is not available, MySQL recovery software come for your help. <br /><br />These are effective third-party applications that help you repair and restore a damaged database in all cases of corruption. They offer absolute recovery using advanced scanning and recovery algorithms. Such applications are useful with MySQL 6.x, 5.x, 4.x, and 3.x versions.

There are two major Storage Engines used by MySQL- MyISAM and InnoDB. In most of the MySQL versions, MyISAM is the standard storage engine that uses older ISAM code as a base. Sometimes, MySQL can not open the files of the MyISAM storage engine and you run across data loss. The problem can be due to corruption to the database and put you in need of <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">MySQL Repair</a> solutions. <br /><br />The MyISAM tables are made up of several files, such as .MYI (MyIndex), .MYD, and .frm files. The MYI is the index file of MyISAM that is used to store the table indexes. However, there are some situations where MySQL can not open the Index file. The most probable reason of this behavior can be corruption to this file. It leads to severe data loss problems and thus you have to repair MySQL database using -advanced MySQL recovery techniques. <br /><br />As an example of this problem with your MySQL database, you may encounter the below error message while accessing data from the database:<br /><br />“can't find file: <tablename>.MYI”<br /><br />At this point of time, it becomes essential to find out the actual cause of the problem and sort it out using MySQL repair tools. <br /><br />Root of the problem:<br /><br />As sated in the above error message, the problem occurs due to corruption to the MYI file. MySQL Index file corruption may be the outcome of unexpected system shutdown, application malfunction, virus infection, improper editing of the database, and more. <br /><br />Resolution:<br /><br />You can <a href="http://www.rsdatabaserecovery.com/">Repair MySQL Database</a> in such situations using any of the following methods:<br /><br />• Check database corruption using inbuilt MySQL commands, like CHECK TABLE, myisamchk, and mysqlcheck. <br />• If corruption is detected, using REPAIR TABLE command to fix it. <br />• In case problem persists, restore MySQL database from recent backup. <br />• When all else fail, use third-party MySQL recovery software to repair and restore the database. <br /><br />Such applications are very handle to effectively fix database corruption in all scenarios. They have pretty simple graphical user interface to offer easy recovery. One of the most popular MySQL recovery software is Stellar Phoenix Database Recovery for MySQL. It works well with both MyISAM and InnoDB storage engines.Saksham

Along with internal system information, these files might also contain user indexes and data. If any of these file(s) get corrupt, the entire database can go inaccessible. The article mentions one of such possible scenarios and then solutions that can help you to Repair MySQL Database.<br /><br />For more clarification, consider a case when a server running MySQL on InnoDB engine undergoes unexpected power outage. After this, when you attempt to start the MySQL database, it might not run and behave abruptly. On viewing the log report for the behavior, you observe the following entries along with the related time stamps and server name:<br /><br />“InnoDB:The log sequence number in ibdata files does not match<br />InnoDB:The log sequence number in the ib_logfiles!<br />InnoDB: Database was not shut down normally<br />InnoDB:Starting crash recovery.<br />InnoDB:Reading tablespace information from the .ibd files...<br />InnoDB:Restoring possible half-written data pages from the doublewrite<br />InnoDB: buffer...<br />InnoDB: Page directory corruption: supremum not pointed to..”<br /><br />The above symptoms indicate table corruption in MySQL database, which might have occurred due to last unexpected power failure. More specifically, the ibdata file(s) have gone damaged.<br /><br />Solution<br /><br />If you encounter above stated or similar problems, try one of the suitable methods to solve it:<br /><ul><li>Check for the last available backup and restore your database.</li><li>In case backup is incomplete, try to repair the database using 'innodb_force_recovery = 4' repair command. However, the command may fail if extent of corruption is high.</li><li>If Innodb repair command has failed, you can delete the ibdata tablespace and recreate it after shutting down the server, if possible. Alternatively, you can rename the ibdata and the ib_log files. But doing so causes data loss. If this is not a suitable method, try the next solution.</li><li>To repair the corrupt MySQL database, use a third-party <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">MySQL Repair</a> utility. These are special tools that can Repair MySQL Database by running the most effective and safe scanning algorithms.

The utility available for upgradation of MySQL tables is known as mysql_upgrade. While upgradation has various advantages, it can also result in complete or partial loss of data from the tables. In such situations, backup enables you to restore the lost data. But, if there is no backup available or it fails to restore the required data, then you need to repair the corrupted table(s). To do so, you need to use advanced MySQL Database Repair applications.<br /><br />Consider a practical scenario, where you upgraded your MySQL database from rev 4.0.13 to rev 4.0.14. After the upgradation is complete, you discover that some of your important tables are corrupted. In addition, when you attempt to open those tables, you encounter the below error message:<br /><br />“e-systemusr/local/mysql/bin# ./myisamchk -a<br />/usr/local/mysql/var/centralf/postscobe1.MYI<br /><br />myisamchk: error: 138 when opening MyISAM-table<br />'/usr/local/mysql/var/centralf/postscobe1.MYI'<br /><br />e-systemusr/local/mysql/bin#.......”<br /><br />The data saved in the MySQL tables becomes inaccessible after the occurrence of the above error message.<br /><br />Cause:<br /><br />The main cause behind corruption of MySQL tables is improper or interrupted upgradation of MySQL database.<br /><br />Resolution:<br /><br />To repair the corrupted MySQL tables and access their data, you will need to follow these steps:<br /><br />· Use the below command to check and analyze the corruption in MySQL table:<br /><br />Check Table tablename<br /><br />· Next, run the below command to repair MySQL table:<br /><br />Repair Table tablename<br /><br />· You can also run the following command:<br /><br /> REPAIR TABLE TABLENAME USE_FRM<br /><br /> Though, it won’t be useful here, as it will show the tables as empty.<br /><br />However, if all the above measures fall short of repairing the corrupted tables, then you will need to use advanced MySQL Repair tools. Such MySQL Database Repair utilities incorporate high end scanning methods to completely repair and restore the data stored in MySQL tables. With self-descriptive and largely graphical user interface, such repair utilities serve as user-friendly solutions that do not require any sound technical skills.<br /></div>Unknownnoreply@blogger.com2tag:blogger.com,1999:blog-1360710309356870369.post-21162847538399184612010-05-19T04:51:00.000-07:002010-12-29T03:40:32.563-08:00External Program Corrupts MyISAM Table<div style="text-align: justify;">There can be numerous factors responsible for the corruption of MyISAM table. Few of the most common are simultaneous modification of table by two different applications (like an external program and by the server), killing of MySQLD process in the middle of a write operation, improper system shutdown, MySQL bugs, and virus attacks. A common symptom of a MyISAM table corruption is the occurrence of the error message when the user attempts to access the records saved in the table. In such cases, the records saved in the MyISAM table become inaccessible. For easy accessibility of table records in such cases, the database user needs to restore the table from an updated backup. But, if the backup is created on a storage media that is not accessible, then the user is not left with any option, but to repair the corrupted table. To effectively do so, the user needs to use an advanced MySQL Database Repair application.<br /></div><br /><div style="text-align: justify;">As a practical case, you use myisamchk (external program) to change the records saved in the Employee (MyISAM) table. However, that same table was also being modified by the server, at the same time. However, when the myisamchk completes its task, and you attempt to view the records saved in the Employee table, you encounter the below error message:<br /></div><br />“Incorrect key file for table: '...'. Try to repair it”<br /><br /><div style="text-align: justify;">After the above error message appears, all the records of Employee table become inaccessible. Moreover, no rows are displayed in the Employee table when you run a query.<br /></div><br />Cause:<br /><br />The main cause for the corruption of the Employee table is simultaneous modification of table by both myisamchk and server.<br /><br />Resolution:<br /><br />To resolve MyISAM table corruption and to access the table data, you need to follow the below steps:<br /><ul><li>Use 'CHECK TABLE' command to check the health of the Employee table.</li><li>Use 'REPAIR TABLE' command to repair the Employee table.<br /></li></ul>While the above steps can repair Employee table in most cases, the possibility of these measures failing to repair the database table still persists. In such situations, you need to search for an effective MySQL Repair application.

The server is also responsible for managing and accessing records that are saved in MySQL data directory. This directory contains all the necessary information, such as, databases, tables, log files, and status files that are required by the user. Interruption in MySQLD process while it is performing some read or write operation on any MyISAM table results into corruption of that table. In such cases, the user encounters an error message while accessing the corrupted table, further resulting in inaccessibility of data saved in that table. To surmount such table corruption error messages, you need to restore data from an updated backup. However, if no backup of the table is available, then the user needs to repair the table using advanced MySQL Repair utility.<br /><br />Consider a practical scenario, where you run an update command on a MyISAM table.

InnoDB is included as a standard storage engine in all modern binaries, which are distributed by MySQL AB. It has ACID (Atomicity, Consistency, Isolation, Durability) compliant-transaction support, along with the foreign key support. However in some situations, you may encounter errors while starting the InnoDB database that indicate database corruption. Corruption renders your database tables inaccessible and cause serious data loss situations. In order to retrieve the damaged database tables you need to restore them from an updated backup. But, if the backup is unavailable, go for <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">MySQL Repair</a> solutions.<br /><br />In a practical scenario, you may encounter startup failure of the InnoDB storage engine with “Signal 11”, prefaced by an unexpected shutdown of the InnoDB. At the same time, you may also come across the below error message:<br /><br />“Page directory corruption: supremum not pointed to.”<br /><br />The server startup variants can not complete successfully. After startup failure, you see the log entries in .err file of MySQL application, similar to the following one:<br /><br />“InnoDB: Error: all log files must be created at the same time.<br />InnoDB: All log files must be created also in database creation.<br />InnoDB: If you want bigger or smaller log files, shut down the<br />InnoDB: database and make sure there were no errors in shutdown.<br />InnoDB: Then delete the existing log files. Edit the .cnf file<br />InnoDB: and start the database again.<br />060218 16:45:01 [ERROR] Default storage engine (InnoDB) is not available<br />060218 16:45:01 [ERROR] Aborting”<br /><br />Cause<br /><br />This issue is caused by the corruption of page directory of InnoDB storage engine. The same problem may also occur if the storage engine or database are corrupted.<br /><br />This overall behavior of MySQL application indicates database corruption and needs MySQL Repair.<br /><br />Resolution<br /><br />You can sort out this problem by replacing the MySQL Server dir with the most recent backup. In case the backup is not updated or is not available in place, situations can be quite difficult to handle manually.<br /><br />In such circumstances, one has to <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">Repair MySQL Database</a> using third party applications. They are particularly designed to methodically scan the database tables and repair, and restore them. You can Recover MySQL database on your own using these self-descriptive applications having interactive user interface.<br /><br />MySQL is an advanced software that successfully restores damaged database in all corruption scenarios. It works well with MySQL 5.x and 4.x. The software supports both InnoDB and MyISAM storage engines and restores all database objects.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1360710309356870369.post-11818750499088585822010-04-30T03:16:00.000-07:002011-01-17T22:10:33.226-08:00Missing or Deleted .frm File May Cause Table Corruption in MySQLMySQL Server database stores data dictionary information in the .frm files that it stores in database directories. On the other hand, InnoDB storage engine keeps information in individual data dictionary in tablespace files. When you move the .frm file or the server gets crashed in halfway of any data dictionary procedure, locations of .frm files might end up out of the synchrony with locations recorded in InnoDB inner data dictionary. In such circumstances, the database may become inconsistent and inaccessible. At this point, you need to opt for <a href="http://filerepairtools.weebly.com/mysql-recovery-software.html">MySQL Recovery</a> to gain access of your valuable data in MySQL database.<br /><br />The out-of-sync data dictionary situation can be indicated by various symptoms. One symptom of this problem is that the “Create Table” statement does not work. When this situation occurs, you should check the error log of server. If the error log indicates that table already exists in InnoDB internal data dictionary, there is an orphaned table in InnoDB tablespace files, which does not have corresponding .frm file.<br /><br />You are allowed to drop orphaned table, using the steps given in error message. If you are unable to run “Drop Table” command successfully, the issue may be caused by name completion in MySQL client. To sort out this issue, start MySQL client with -skip-auto-rehash option and try using Drop Table command.<br /><br />Another symptom of the out-of-sync issue with data dictionary is the error message that MySQL gives when you try to open a database table:<br /><br />“ERROR 1016: Can't open file: 'child2.InnoDB'.
