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 ?
