Case Study

Tools

You can download the tools which we used in our case study.

For each tool, do the following

  1. Unpack them by executing
    tar xfz lola-x.tar.gz
  2. Configure them by executing
    cd lola-x
    ./configure

where lola may be replaced by the respective tool

Process Models

Experiments were performed on both services and their partners obtained from decomposing process models from 4 libraries (A, B1, B2, B3).

* For fingerprint/fingerprint compatibility check download the services and their partners in OWFN file format: A,B1,B2,B3

* For state space analysis, download the compositions in LoLA file format and the task files, A lola files, B1 lola files, B2 lola files, B3 lola files

Obtain Fingerprints with Linda

To compute octagon (using terms of type x-y, x+y, x) fingerprints for open nets, execute

linda net.owfn -2 -o net.output

Check Compatibility with Yasmina

To execute compatibility check using ILP using the fingerprint/fingerprint check

  • yasmina -m net.output -m netpartner.output

Check Compatibility with LoLA

To use LoLA to check for weak termination of composed processes, proceed as follows:

  1. Compile another version of LoLA to check for liveness of state predicate by executing
    make lola-liveprop1
  2. Execute
    lola-liveprop1 net.lola -a netpartner.task

Results

The experimental results comparing the state-based approach vs. the fingerprint approach are depicted in the following table. Experimental Results
