Hi Guys, We have the following deployment for Syncope:
Tomcat1 – Syncope1 – SinglePostgresDB tomcat2 – Syncope2 - SinglePostgresDB Both these tomcats are not in cluster. Syncope1 and Syncope1 are independent instances and not in cluster as well. Both these Syncope instances use a common single PostgresDB. Both the tomcats are behind a LoadBalancer and the application requests ELB for accessing Syncope so that load is randomly distributed. With this deployment sometimes our application works!! But sometimes when the application tries to delete a user or change password, one of the Syncope throws an error: 09:58:21.999 DEBUG org.apache.syncope.core.rest.controller.ControllerHandler - Unresolved bean reference ... 09:58:22.156 DEBUG org.apache.syncope.core.rest.controller.ControllerHandler - After throwing UserController.search 09:58:22.158 ERROR org.apache.syncope.core.rest.utils.RestServiceExceptionMapper - Exception thrown by REST method: null java.lang.NullPointerException 09:59:21.564 DEBUG org.apache.syncope.core.rest.controller.ControllerHandler - Before UserController.search([org.apache.syncope.core.persistence.dao.search.SearchCond@35f75285[ type=LEAF subjectCond=<null> attributeCond=org.apache.syncope.core.persistence.dao.search.AttributeCond@4ab571[ type=EQ schema=accountName expression=testAccount ] And additionally we have warnings in the logs: "message": "410373728 syncopePersistenceUnit WARN [http-bio-8080-exec-2529] openjpa.Runtime - Detected possible orphaned reference to deleted object \"[9899]\" in \"org.apache.syncope.core.persistence.beans.user.UAttr.values<element:class org.apache.syncope.core.persistence.beans.user.UAttrValue>\" of instance \"10764\".”, After these errors, this Syncope instance always results error and if I try to login to Syncope-Console UI, I cannot connect to the Users tab….it results into error “Error in core” Question is, is it a valid deployment scenario?? Is Syncope expected to work in such a deployment? Or we need to setup tomcat/Syncope in cluster and only then it is expected to work?? Can someone please provide hints!!! Thanks, Anubhav
