Sequoia provides high availability and performance scalability for databases. It is is the continuation of the C-JDBC project. It provides transparent database clustering (partitioning, replication, etc.). It works with any Java application without code modification and with any database engine. It has been successfully tested with Tomcat, JBoss, JOnAS, WebSphere, MySQL, PostgreSQL, Apache Derby, HSQLDB, SAP DB, Oracle, DB2, Sybase, MS SQL Server, Firebird, and more.
ldapsync.pl is a simple Perl script that uses Net::LDAP to copy new and updated records to a second LDAP server. Although most LDAP servers offer some sort of replication facility, this approach allows the frequency of updates to be controlled. It can be used to copy information between LDAP servers in different security layers without the individual servers having permission to contact each other. It was developed using the SunONE Directory Server on Solaris 9.
DB Copy Plugin is a database copying plugin for the SQuirreL SQL Client. It makes it possible to copy and paste tables from one session to another and between different databases and includes primary key and foreign key constraints for copied tables, and uses Hibernate 3.0 internally to perform database object type mappings. It supports Firebird, Oracle, Sybase, MS SQL Server, MySQL, HyperSonic, Pointbase, and PostgreSQL, and allows the user to select a Hibernate dialect for the destination database if one couldn't be determined automatically.
