SUPPORT / SAMPLES & SAS NOTES
Problem Note 69896: The SAS® Intelligent Decisioning 5.6 sas-viya-decisiondefinitions-default service does not start
 |  |  |  |  |
When you restart all viya services, the sas-decisiondefinitions-default service is the only service that is not ready. The rest of the viya service show a status of up. Also, when you restart sas-decisiondefinitions-defautl service using the following code, it shows an up status:
sudo systemctl restart sas-viya-decisiondefinitions-default
When the sas-viya-decisiondefinitions-default service does not show a status of up, the decisions and treatments are not available in the SAS® Model manager GUI.
In this scenario, the /opt/sas/viya/config/var/log/decisiondefinitions/default/sas-decisiondefinitions_<date timestamp>.log file shows messages similar to the following:
