Re: SAP sybase replication materialize phase error

Hi Mohammed,

 

Thank you for providing the details.  I think the issue is a timing related issue.

 

When a 'dump' is executed in ASE, a 'marker' is recorded in the transaction loog indicating the point where the dump is complete.  Replication Server is sent this 'marker' and will use the marker to determine when to apply data.  Activity prior to the marker is assumed to be in the dump, and is not applied by Replication Server.  Everything after the 'marker' is assumed to NOT exist in the dump and will be applied.

 

The timing challenge - the marker is created for both dump 'database' and 'transaction'.  And Replication Server will process the 'first' marker is sees.  So I think the issue is Replication is starting after the  'database' dump, and not waiting for the 'transaction' dump.

 

To change the timing, you need to perform you database dump 'before' you request manual materialization.

 

1) Dump database

2) Wait to ensure this dump's marker has been skipped by Replication Server - a few minutes should be OK.

3) Select manual dump/load database (will process 'next' dump marker seen).

4) Dump tran

5) Load both database and tran

6) OK to proceed.

 

Regards,
Stephen
