Hi, One of our client is having problem with VSS and SQL Anywhere (16.0.0.1948). When performing a backup, VmWare snapshot, this error occurs: IVssWriterCallback. hr = 0x80040154. In the Windows event log we have: Opération : Données du rédacteur en cours de collecte Contexte : ID de classe du rédacteur: {6bded7ca-b593-455b-9b58-c40aa408d5ba} Nom du rédacteur: SQLAnywhere VSS Writer ID d’instance du rédacteur: {a8919400-fd5d-4942-a877-93a572cb6d10} The "vssadmin list writers" command does not list any problem, but the SQL Anywhere VSS writer is not listed. The SA VSS service was re-installed, is running and I see in the DB server console that the server is successfully registered with the VSS service. Any suggestion on what could be the cause of the problem or additional diagnostic ? |
I have no suggestion but wanted to note that in our setups with MS Hyper-V, the console log not only shows that the SA VSS service is registered but has regular appearing entries that the service is "identified" (each 2 hours, apparently):
and shows a group of statements once a copy is made (triggering a checkpoint), in our case once a day:
Sorry for the German locale but I guess you'll get the impression.
Nothing to suggest either but note that the error code is: REGDB_E_CLASSNOTREG 0x80040154 Class not registered
