Subject [jira] [Created] (DIRSERVER-1704) Inconistency in Master-Slave Replication
Date Mon, 09 Apr 2012 08:47:23 GMT
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


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 ?
