Example 17 with BPSFault

use of org.wso2.carbon.bpmn.core.BPSFault in project carbon-business-process by wso2.

the class TenantRepository method fixDeployments.

/**
 * Information about BPMN deployments are recorded in 3 places:
 * Activiti database, Registry and the file system (deployment folder).
 * If information about a particular deployment is not recorded in all these 3 places, BPS may not work correctly.
 * Therefore, this method checks whether deployments are recorded in all these places and undeploys packages, if
 * they are missing in few places in an inconsistent way.
 * <p/>
 * As there are 3 places, there are 8 ways a package can be placed. These cases are handled as follows:
 * (1) Whenever a package is not in the deployment folder, it is undeploye (this covers 4 combinations).
 * (2) If a package is in all 3 places, it is a proper deployment and it is left untouched.
 * (3) If a package is only in the deployment folder, it is a new deployment. This will be handled by the deployer.
 * (4) If a package is in the deployment folder AND it is in either registry or Activiti DB (but not both), then it is an inconsistent deployment. This will be undeployed.
