Ontem, 19 de setembro de 2010, no evento inaugural do MySQL sunday no Oracle OpenWorld, anunciou o MySQL 5,5 Release Candidate. O candidato MySQL 5,5 ajuda a melhorar o desempenho e a escalabilidade de aplicações em diversos ambientes operacionais, incluindo Windows, Linux e Mac.
As melhorias incluem:
Improved performance and scalability:
MySQL Server and InnoDB have been enhanced to provide optimum performance and scalability when running on the latest multi-CPU and multi-core hardware and operating systems.
InnoDB is now the default storage engine for MySQL Server, delivering ACID transactions, referential integrity, and crash recovery.
Higher availability:
New semi-synchronous replication improves failover reliability by allowing the master to proceed without waiting for all the slaves to acknowledge. Once one slave acknowledges, the transaction can be committed. This also helps improve data integrity.
Replication Heart Beat enables faster detection, diagnosis and correction of master/slave synchronization issues, helping improve the reliability and availability of data by reducing the risk and impact of master/slave synchronization issues.
Improved usability:
Improved index and table partitioning enables RANGE and LIST partitions to be defined on date, datetime, varchar, and char columns, simplifying and extending MySQL and adding flexibility to indexing and query tuning.
DBAs and developers can save time using the ANSI/ISO standard SIGNAL/RESIGNAL syntax inside stored routines, including triggers, to raise an error condition invoking specific error handling within their applications.
Enhanced diagnostics, including a new ERFORMANCE_SCHEMA, provide low-level diagnostics on MySQL server performance statistics, allowing DBAs to pinpoint resource-intensive processes and events, streamlining efforts and helping to enhance their productivity.

Ao instalar um client do oracle em um Windows 2003 Server 64-bits com a opção de ter o drive ODBC instalado, me deparei com algo meio que óbvio, porem para achar o bendito aplicativo ou como registrar o drive 32bit num OS 64bit não foi simples.
"A versão de 32 bits da ferramenta Administrador de ODBC e a versão de 64 bits da ferramenta administrador ODBC exibem os DSNs de usuário de 32 bits e os DSNs de usuário de 64 bits em uma versão de 64-bit do sistema operacional Windows"
