Scientific workflows: vine:toolkit module as a part of the Serpens suite for Kepler

Serpens project: Serpens suite for Kepler is a set of actors, composites and workflows that provide support for different grid middleware stacks - (e.g. gLite and UNICORE). The extension covers the standard activities related to remote job management: job submission, monitoring, data handling, and so on.

Certificate Manager updated

Certificate Manager project has been updated. New features has been added: certificate configuration from p12 and jks keystore files or from web browser keystores (Internet Explorer, Firefox), minor fixes to the look and feel. Documenatation is also updated - read the article here.

Tomcat 6 support

Vine Toolkit is prepared now to work with Tomcat 6 servlet container. To use the feature it is enough to set container type in the currently used installer to 'tomcat_6_x' value and have Tomcat 6 installed in the target path. The changes involved different components so it is required to update your Vine sources against the svn repository. Different installation types were checked and validated with success after changes:

- Liferay 5.2.3 + Tomcat 5
- Liferay 5.2.3 + Tomcat 6
- GridSphere 3.1 + Tomcat 5
- GridSphere 3.2 + Tomcat 5
- GridSphere 3.2 + Tomcat 6

Vine configuration - HSQL DB tuning

By default Vine uses HSQL database. In general the default settings are used, but if required it is possible to change them after Vine installation.

The HSQL Vine DB configuration file is located here:

$PORTAL_HOME\webapps\vine\WEB-INF\vine\persistence\database\vine.properties

Inside there are numerous HSQL DB settings.

One of it is particularly interesting:

hsqldb.default_table_type=memory
