Functionality
The functionality provided by this messages is determined by the required interactions specified in the Topology Service resources page
Installation
The Topology Service is a Java Web Service that requires the following components:
- JAVA 1.5 (runtime and development environment)
- PostgreSQL 8
- Apache Tomcat & Axis
Some of this components must be installed in advance, others can be automatically installed with ToS installation process. Please follow the installation instructions for more details.
The service has not been verified yet to allow it run along with other perfSonar services concurrently. There should not be a problem to install them in the same machine though.
Client/Server interactions (Message exchange)
A perfsonar message exchange can include several requests. There are two types of message exchanges in the Tops:
- Database downloads requests triggered by client. The client requests full or partial database download but currently partial download is supported.
- Database downloads triggered by server. This happens when when a modification is done and the client previously wanted to be notified to download the information if the selection of the database is done.
