Hello,
DBStore will save some properties to database when it "doDeactivate()". But
when CDO Server is shut down abnormally, the last commit time will not be
saved. This will cause OfflineClone can not sync properly after CDO Server
restart. How to solve this problem?

I thought this problem has been solved right before Helios GA:

316867: Raw replication fails after recovering from non-graceful shutdown
https://bugs.eclipse.org/bugs/show_bug.cgi?id=316867

What version of CDO are you using?

Cheers

Can you try to set a breakpoint here: org.eclipse.emf.cdo.server.internal.db.DBStore.reStart()
And find out if the last lines are executed and what they're doing:

long lastCommitTime = DBUtil.selectMaximumLong(connection, CDODBSchema.COMMIT_INFOS_TIMESTAMP);
setLastCommitTime(lastCommitTime);

long lastNonLocalCommitTime = DBUtil.selectMaximumLong(connection, CDODBSchema.COMMIT_INFOS_TIMESTAMP,
CDOBranch.MAIN_BRANCH_ID + "<=" + CDODBSchema.COMMIT_INFOS_BRANCH);
setLastNonLocalCommitTime(lastNonLocalCommitTime);

Cheers
/Eike

Apologies, there was a wrong auto-comment on the bugzilla (as Pascal pointed out)!

Although 3.0 GA was on June 29, the final GA build was already on June 14, one
day before this fix was committed.

Hence this fix was first released with SR1.

Cheers
