The following documentation is available on-line. A best effort is made to keep the versions available here synchronized with the most recent release, but that sychronization should not be relied upon.
- admin-guide.pdf describes the downloading, building, and installation of the Onasys software package.
- user-guide.pdf describes the use of the onasysd daemon and associated tools. It is far from complete, but is hopefully enough to help you tune the daemon to your pipeline's needs.
- OnasysWeb installation guide.
- onasys library reference is a browsable description of the code in the onasys Python library.
- dagdbUpdator library reference is a browsable description of the code in the dagdbUpdator Python library.
