Troubleshooting Installation Issues

R

This page attempts to document common installation related issues encountered by Bahmni community users, and how to troubleshoot / debug issues.

OpenERP Sync Issue

If there is an issue with syncing data from OpenMRS to OpenERP. 

Step 1: Check service status

After installation, If you see openmrs to openerp sync not working. Firstly, you need to check if bahmni-erp-connect is running. 

sudo service bahmni-erp-connect status // Check the status
sudo service bahmni-erp-connect start // To start the service , if it is not running

Step 2: Check markers table

If you still see the sync issue, try to check the markers table in openerp if there is an entry for reading the corresponding feed from openmrs.

Example: This entry in openerp database is for reading patient feed from openmrs to openerp
 Entry in Markers table for patient feed from openmrs to openerp

Make sure the markers are in sync

Step 3: Check failed_events table

Check the failed_events table for any entries recorded. 

Please refer Atom Feed Based Synchronization in Bahmni for more details about atom feed sync.


Services stopped after system reboot

Make sure you have at least 8GB RAM to have all the services start automatically during system reboot


If you see that some services are always stopped after system reboot, then you can choose to automatically start the services at the time of system start. Please use the below command to enable the service start.

Command to start the service at system reboot
chkconfig {service_name} on

Example:

Using the above command, lets say you would like to start openerp service, use the following command.

Example command to start openerp service
chkconfig openerp on //openerp is the service name 

Services in Bahmni

Similarly, one can choose to start any service. Refer Install Bahmni on CentOS#BahmniServices to see the available services in Bahmni
