fkchk is a MySQL InnoDB/XtraDB foreign key checker and repairer. It is useful if you suspect that your database's foreign keys may be broken, or if you disable foreign key checks and now want to be sure that the data is consistent. It is also useful if you have suffered a performance hit and want to check the consistency of foreign keys to verify that they're not the reason. It can attempt to repair any issues it finds, but this option should not be used and is only implemented for testing purposes.
Valentina Studio is a GUI manager for local files of Valentina DB, SQLite, MySQL, PostgreSQL, and Valentina DB Server.

Bear is a lightweight remote automation tool for Groovy/Java/JVM. It allows you to deploy projects, setup your cluster, and install software to your remote machines. It differs from other existing tools in that it uses a programmatic approach - your deployment is a regular Java class. It also uses static types, chained method calls, FP, and fluent programming techniques.
Zorka is a sophisticated programmable profiling/monitoring agent for Java suitable for running with production applications. The agent integrates seamlessly with popular monitoring systems and protocols (Zabbix, Nagios, syslog, SNMP) and offers additional tracing/profiling capabilities that - along with the accompanying data collector - help with spotting performance issues and general problems. The agent also exposes JMX data to conventional monitoring systems. Platforms (more or less) supported out of the box include: JBoss 4/5/6/7, Wildfly 8, Tomcat 6/7/8, Jetty 6/7/8/9, Websphere, Weblogic, GlassFish 4.0, WSO2 ESB, Mule ESB, and Jasig CAS. There is also dedicated support for the popular Java libraries Spring, Quartz, CXF, and Axis 1.x. The agent should run on most other platforms with limited functionalities (that is, lack of support for platform-specific features). It works with JDK6, JDK7, and JDK8. JDK5 support is also possible after preprocessing the agent binary with retrotranslator. Functionality can be easily added by implementing simple BSH scripts.
