MySQL Cluster + replication
Lokacija: Zanimljivi linkovi :: MySQL   |   Autor: cacan @ 3:00   |  

You may know about the MySQL Cluster, which is a complex architecture to achieve high availability and performance. One of the advantages of MySQL Cluster is that each node is a peer to the others, whereas in a normal replicating system you have a master and many slaves, and applications must be careful to write only to the master.

The main disadvantages of MySQL Cluster are (as of MySQL 5.0):

* The database is in memory only, thus requiring more resources than a normal MySQL database. (MySQL 5.1 introduces table spaces, with the capability of storing nonindexed data on disk.)
* Some normal features are not available, such as full-text searches, referential integrity, and transaction isolation levels higher than READ COMMITTED.

There are some cases where the MySQL Cluster is the perfect solution, but for the vast majority, replication is still the best choice.

Replication, too, has its problems, though:

* There is a fastidious distinction between master and slaves. Your applications must be replication-aware, so that they will write on the master and read from the slaves. It would be so nice to have a replication array where you could use all the nodes in the same way, and every node could be at the same time master and slave.
* There is the fail-over problem. When the master fails, it’s true that you have the slaves ready to replace it, but the process of detecting the failure and acting upon it requires the administrator’s intervention.

Fixing these two misfeatures is exactly the purpose of this article. Using features introduced in MySQL 5.0 and 5.1, it is possible to build a replication system where all nodes act as master and slave at the same time, with a built-in fail-over mechanism.

    MySync - MySQL - Synchronisation without ODBC-Connection
    Lokacija: WebDev :: MySQL   |   Autor: cacan @ 14:51   |  

    MySync - MySQL - Synchronisation without ODBC-Connection

  • MySync
    Do they know the problem? You have a MySQL data base with your Web account and need the data also at home on your client PC to work on there. For safety reasons it is mostly not possible to access the Web MySQL data base with a ODBC connection.
    MMySync is the solution
    MySync needs no ODBC connection, because it synchronizes the MySQL data base by ftp and PHP access. They can define as many as desired jobs, which synchronize the data automatically between the client and the Web data base. In addition the possibility exists to call also other php documents time-steered, in order to thus update server data. itig Daten zu aktualisieren.
