> Inconistency in Master-Slave Replication
> ----------------------------------------
>
> Key: DIRSERVER-1704
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1704
> Project: Directory ApacheDS
> Issue Type: Bug
> Affects Versions: 2.0.0-M6
> Environment: OS : Windows XP Professional Version 2002, Service Pack 3
> Hardware : Intel 1.73 Ghz, 2 GB RAM
> Reporter: Amod Kadam
> Priority: Critical
> Labels: replication
>
> We are testing master-slave configuration for ApacheDS and observed
> inconsistency when data from MASTER gets
> deleted. The record gets deleted from MASTER but does not get deleted from
> SLAVE. However this does not happen
> always. Secondly we are unable to find out the pattern for the same.
> We have seen this issue after executing the Test Cases in sequence.
> Scenario - Master changes state from RUNNING to STOP and then RUNNING again
> while Slave is in 'RUNNING' state
> Ensure that MASTER and SLAVE are running before executing each test case.
> ========================================================
> Test Case No: 1
> 1) Stop Master
> 2) Restart MASTER
> 3) Add an entry to the MASTER
> dn: cn=amodkadam,ou=users,ou=system
> objectClass: person
> objectClass: top
> sn: kadam
> cn: amodkadam
> Expected Result :
> SLAVE should get corresponding entry for
> dn: cn=amodkadam,ou=users,ou=system
> Actual Test Result:
> Same as expected result.
> ===========================================
> Test Case No:2
> 1) Stop Master
> 2) Restart MASTER
> 3) UPDATE an entry in the MASTER
> dn: cn=amodkadam,ou=users,ou=system
> objectClass: person
> objectClass: top
> sn: kadam_update
> cn: amodkadam
> Expected Result :
> SLAVE should have UPDATED entry for
> dn: cn=amodkadam,ou=users,ou=system
> Actual Test Result:
> Same as expected
> ================================================
> 1) Stop Master
> 2) Restart MASTER
> 3) DELETE an entry from the MASTER
> dn: cn=amodkadam,ou=users,ou=system
> objectClass: person
> objectClass: top
> sn: KADAM
> cn: amodkadam
> Expected Result :
> Corresponding entry should be deleted from SLAVE but does not get DELETED
> Actual Result
> Fails and the record in the SLAVE does not get deleted.
> However this does not happen alwyas.
> =========================================================================
> Could you let us know what could be issue and how to fix it ?
